[0013] (4) granulating the mixture to obtain granules.

[0014] According to the method for preparing a concentrate supplement for Inner Mongolia cashmere goats in some embodiments of the present application, the mesh sizes of the upper and lower sieves of the double-layer primary cleaning sieve are 8 mm and 3 mm, respectively.

[0015] According to the method for preparing a concentrate supplement for Inner Mongolia cashmere goats in some embodiments of the present application, the granulation ring die compression ratio of the granules is 1:8, the particle size is 4.5 mm, and the particle length is 12 mm.

[0016] On the fourth aspect, according to the feeding method of concentrate supplement for improving the lambing rate of Inner Mongolia cashmere goats in some embodiments of the present application, the grazing Inner Mongolia cashmere goats are fed concentrate supplement every day starting from about one month before breeding, and the ewes are fed the concentrate supplement for about one month after breeding, and the supplementary feeding time is about two months, and the ewes are fed about 0.4 kg of concentrate supplement every day, wherein the concentrate supplement is the Inner Mongolia cashmere goat concentrate supplement described in the right.

[0017] According to the feeding method of concentrate supplement for improving lambing rate of Inner Mongolia cashmere goats in some embodiments of the present application, the Inner Mongolia cashmere goats are Albas type white cashmere goats.

[0018] In the fifth aspect, according to some embodiments of the present application, the concentrate supplement for Inner Mongolia cashmere goats is used in supplementary feeding of Albas white cashmere goats.

[0019] Beneficial effects: The present invention can supplement the nutrition of the breeding ewes of the Albas type Inner Mongolian white cashmere goats in Ordos before and after mating, which can increase the weight of the breeding ewes, increase the ovulation rate and the implantation rate of the fertilized eggs, and thus increase their lambing rate. At the same time, it can increase the birth weight of the lambs, the wool production of the ewes, and is conducive to increasing the weight of the ewes in the next year, wherein:

[0020] In the first aspect, the present invention supplements nutrition to the breeding ewes of the Ordos Albas type Inner Mongolian white cashmere goats before and after mating, which can increase the weight of the breeding ewes, increase the ovulation rate and the implantation rate of the fertilized eggs, and thus increase the lambing rate:

[0021] Multiple births are the basis for high productivity and high yield in sheep farming. With the improvement of breeding level, the number of twin lambs of single-birth Ordos Albas white cashmere goats has gradually increased, but it is still in a low reproductive rate status and cannot meet the market demand for white cashmere goat wool and high-quality mutton. The present invention is used for white cashmere goats in grazing period. Before the white cashmere goats are mated, the nutritional status of grazing sheep is improved before and after mating, and the ovulation rate of Albas white cashmere goats is improved.

[0022] After the female ewe is born, a follicle bank consisting of a large number of primordial follicles and growing follicles is formed on the ovary. In the subsequent reproductive process, the development of follicles is a completely dynamic process. In each estrus cycle, there is a group of follicles growing and developing at the same time, with a number of 500 to 1000, but the vast majority (99.9%) of them are closed and degenerated during the development process, and only a very small number of dominant follicles mature to ovulation. The reason why the development of follicles presents a special physiological phenomenon is generally believed to be related to the follicle development characteristics and reproductive endocrine regulation in the estrus cycle, and reproductive endocrine is closely related to nutritional status. The present invention improves the nutrition of ewes before and after mating, improves the formation rate of dominant follicles, and promotes the formation of corpus luteum, thereby ensuring the implantation rate of fertilized eggs.

[0023] The present invention combines the fatness of the basic ewes and selects the Inner Mongolia cashmere goat concentrate supplement of the present invention for supplementary feeding for 60 days, which can effectively increase the weight of the ewes, improve their nutritional status, increase the ovulation rate, and increase the formation rate of the dominant follicles. Experiments show that the average daily weight gain of the ewes is increased by 20.3g / day and 33.4g / day respectively compared with the control group. The Inner Mongolia cashmere goat concentrate supplement of the present invention can increase the lambing rate of the ewes. By supplementing for 60 days before and after mating, the lambing rates of the two experimental groups reached 154.1% and 163.3% respectively, which were increased by 20.8% and 30% respectively compared with the control group, and had a significant effect.

[0024] In the second aspect, the present invention supplements nutrition to the breeding ewes of the Albas type Inner Mongolian white cashmere goats in Ordos before and after mating, which can increase the birth weight of the lambs: birth weight is an indicator that affects the survival rate of lambs. The weight of the breeding ewes before and after mating not only affects the lambing rate, but also has an important impact on the birth weight of the fetus and the weight of the ewes in the following year. The present invention supplements the Inner Mongolian cashmere goats with the concentrate supplement of the present invention for 60 days before and after mating, and the other times are the same as the feeding and management of the control group. After supplementary feeding, the birth weight of single lambs after lambing is increased by about 0.24kg and 0.33kg, and there is no obvious change in twin lambs.

[0025] On the third aspect, the present invention supplements nutrition to the breeding ewes of the Albas-type Inner Mongolian white cashmere goats in Ordos before and after mating, which can increase the wool production and the weight of the ewes in the next year: in the textile industry, the wool production reflects the importance of wool quality, and the higher the wool production, the better the product quality. Wool production is related to the nutritional level, and nutritional imbalance or deficiency can reduce wool production. The wool production of the ewes in the experimental group of the present invention has increased, and the experimental group 2 has increased by about 0.15kg compared with the control group, and the weight after fleecing has also increased.

[0026] In the fourth aspect, the protein content of Artemisia sphaerocephala meal is 52.19%, and it contains 4.47% crude fat and polyphenols. Its protein quality is higher than that of soybean meal protein. Artemisia sphaerocephala oil is rich in unsaturated fatty acids, VE and polyphenols, of which unsaturated fatty acids are as high as 91%, vitamin content is 1.5%-2%, (VE content is 1.12%), polyphenols are 3-5%, and it also contains compounds of mineral elements such as phosphorus, calcium, and iron. Because the fat content of this formula feed is relatively high, and the VE and polyphenols in Artemisia sphaerocephala oil and polyphenols in Artemisia sphaerocephala meal have the function of scavenging free radicals and inhibiting lipid peroxidation, which can effectively prevent the oxidation of vegetable oil and be fully absorbed and utilized by the body, solving the negative energy balance while reducing follicular atresia and increasing the number of mature follicles discharged. At the same time, the polyphenols contained in Artemisia sphaerocephala oil have antibacterial and anti-inflammatory effects, which can effectively reduce gastroenteritis in maternal animals, adjust gastrointestinal function, thereby increasing feed intake, improving the overall body condition of cashmere goats, ensuring conception rate, lamb birth weight and survival rate, and ultimately improving the lambing rate and survival rate of cashmere goats. DETAILED DESCRIPTION

[0027] The disclosed embodiments are described to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.

[0028] In some embodiments of the first aspect, the present invention proposes a concentrate supplement for Inner Mongolia cashmere goats, including 30-40 parts of corn, 15-25 parts of puffed corn husks, 8-15 parts of soybean meal, 4-8 parts of cottonseed meal, 8-15 parts of DDGS (distillers grains protein feed), 2.5-6.5 parts of protein powder, 2-4 parts of palmitic acid fatty acid calcium, 0.7-1.2 parts of corn oil, 0.01-0.05 parts of complex enzyme preparation, 0.8-1.2 parts of calcium hydrogen phosphate, 1.5-2.5 parts of stone powder, 0.7-1.1 parts of sodium chloride, 0.8-1.1 parts of sodium bicarbonate, and 1.0-2.0 parts of premix.

[0029] According to some embodiments of the first aspect, the present invention adds corn oil, palmitic acid fatty acid calcium, protein powder and compound enzyme preparation in appropriate amounts to the Inner Mongolia cashmere goat concentrate supplement. Among them, corn oil and palmitic acid fatty acid calcium can increase energy, and protein powder can increase protein content. Based on this, corn oil, palmitic acid fatty acid calcium and protein powder synergistically inhibit oocyte atresia, increase the discharge of mature follicles, and have the effect of promoting estrus of ewes, thereby being able to improve the conception rate and lambing rate of ewes.

[0030] Preferably, the composite enzyme preparation of the present invention mainly includes cellulase, α-amylase, and β-glucanase, that is, the composite enzyme preparation of the present invention is a composite enzyme preparation based on cellulase, α-amylase, and β-glucanase. In a more preferred embodiment, the cellulase, α-amylase, and β-glucanase in the composite enzyme preparation are measured by mass, and the ratio of cellulase: α-amylase: β-glucanase = 10:1:5. The composite enzyme preparation may also include other types of enzymes, such as xylanase, acid protease, neutral protease, etc. The composite enzyme preparation has the function of improving immunity, can improve the appetite of sheep, increase the digestibility and utilization rate of forage, and thus can improve the absorption rate of forage, so that the body condition of sheep is improved. In a more preferred embodiment, the composite enzyme preparation uses the composite enzyme preparation of the product name Yidu Enzyme A-F821 produced by Guangdong Yiduli Biotechnology Co., Ltd.

[0031] Based on the above, the present invention improves the nutritional level and body condition of sheep as a whole, has a strong stimulating effect on estrus of sheep, and synergistically improves the nutritional level and body condition, improves the formation of dominant follicles, and promotes the formation of corpus luteum to ensure the implantation rate of fertilized eggs. It can be seen that the concentrate supplement of the present invention can enhance the reproductive willingness of ewes, further improve the implantation possibility of fertilized eggs of ewes, and can enhance the physique of ewes, and comprehensively improve the conception rate and lambing rate of ewes.

[0032] In some embodiments of the second aspect, the present invention proposes a concentrate supplement for Inner Mongolia cashmere goats, including 30-40 parts of corn, 15-25 parts of puffed corn husks, 3-8 parts of soybean meal, 4-8 parts of cottonseed meal, 3-8 parts of wormwood meal, 8-15 parts of DDGS, 2-6 parts of protein powder, 2-4 parts of palmitic acid fatty acid calcium, 0.3-0.7 parts of corn oil, 3-5 parts of wormwood seed oil, 0.01-0.05 parts of complex enzyme preparation, 0.8-1.2 parts of calcium hydrogen phosphate, 1.5-2.5 parts of stone powder, 0.7-1.1 parts of sodium chloride, 0.8-1.1 parts of sodium bicarbonate, and 1.0-2.0 parts of premix.

[0033] In these embodiments of the second aspect, the present invention further adds an appropriate amount of Artemisia ordosica meal and Artemisia ordosica seed oil to the supplementary feed of Inner Mongolia cashmere goats. Energy is the heat basis of life activities. If the energy supply is insufficient, it will affect the growth and development of the ewe's follicles and the maturation and ovulation of the oocytes, and affect the normal growth and development of the embryo and the fetus. Energy regulates hormone metabolism in the body, thereby affecting the secretion of pituitary gonadotropin, affecting the growth and development of follicles and the maturation and ovulation of oocytes, and affecting the normal growth and development of the embryo and the fetus. The inventor found that VE is closely related to reproductive function. It secretes gonadotropin through the anterior pituitary to regulate sexual function. VE can enhance ovarian function and increase luteal cells in follicles. Supplementing VE in the diet can not only improve the conception rate of ewes, reduce fetal death, increase the number of litters, but also enhance the immunity and anti-stress ability of young animals, reduce the death of young animals before weaning, shorten the interval from weaning to estrus in ewes, and improve the quality of ram semen. The protein content of Artemisia sphaerocephala meal is 52.19%, and it contains 4.47% crude fat and polyphenols. Its protein quality is higher than that of soybean meal protein. Artemisia sphaerocephala oil is rich in unsaturated fatty acids, VE and polyphenols, of which unsaturated fatty acids are as high as 91%, vitamin content is 1.5%-2%, (VE content is 1.12%), polyphenols are 3-5%, and it also contains compounds of mineral elements such as phosphorus, calcium, and iron. Because the fat content of this formula feed is relatively high, the VE, polyphenols in Artemisia sphaerocephala oil and polyphenols in Artemisia sphaerocephala meal have the function of scavenging free radicals and inhibiting lipid peroxidation, which can effectively prevent the oxidation of vegetable oil, be fully absorbed and utilized by the body, solve the negative energy balance, reduce follicular atresia, and increase the number of mature follicles discharged. At the same time, the polyphenols contained in Artemisia sphaerocephala oil have antibacterial and anti-inflammatory effects, which can effectively reduce gastroenteritis in female animals, adjust gastrointestinal function, thereby increasing feed intake, improving the overall body condition of cashmere goats, and ensuring conception rate, lamb birth weight and survival rate. Ultimately, the lambing rate and survival rate of cashmere goats will be improved.

[0057] Experimental Example 1: In the experiment, 270 healthy adult multiparous Albas-type Inner Mongolian white cashmere goat ewes (hereinafter referred to as experimental ewes) of similar breeding age and weight raised in Ordos area were divided into three treatment groups, each treatment group included 3 replicate groups, and each replicate group had 30 ewes.

[0058] Treatment group 1 is the control group, the control group is fed with the white cashmere goat concentrate supplement (commercially available) described in comparative example 1, treatment group 2 is experimental group 1, experimental group 1 is fed with the Inner Mongolia cashmere goat concentrate supplement described in example 1, and treatment group 3 is experimental group 2, experimental group 2 is fed with the Inner Mongolia cashmere goat concentrate supplement described in example 2. Among them, all experimental ewes were raised under grazing conditions and supplemented with 0.4 kg / head of concentrate supplement per day.

[0059] The experiment includes a pre-experimental period and a formal experimental period. The pre-experimental period is 10 days before the formal experiment. During the pre-experimental period, the sheep flocks are grouped according to the above grouping method, and feed transition is carried out after grouping.

[0060] The formal experiment requires that the experimental ewes be fed with concentrate supplements from one month before breeding, and the feeding period is two months. The breeding of white cashmere goats in the Ordos region mainly starts in October. In the experimental case, the formal experiment started in September, and breeding began after feeding concentrate supplements for 30 days, for a total of 60 days.

[0061] The experimental ewes were weighed for the first time before the formal experiment began, the second time after 30 days of formal feeding, and the third time after 60 days of formal feeding. The number of lambs born by the experimental ewes, the lamb birth weight, the wool production of the experimental ewes, and the weight after wool collection were tracked and recorded in the following year.

After feeding the feed of the present invention, the nutritional needs of the Inner Mongolia cashmere goats before and after breeding can be met under grazing conditions. The birth weight of the lambs, the wool production of the ewes and the weight after wool collection in the experimental group are all higher than those in the control group. Example 2 further adds Artemisia sphaerocephala meal and Artemisia sphaerocephala seed oil, which can further improve the lambing rate of the breeding ewes of the white cashmere goats, further meet the nutritional needs of the Inner Mongolia cashmere goats before and after breeding, and increase the birth weight of the lambs, the wool production of the ewes and the weight after wool collection.

At the same time, it can increase the birth weight of the lambs and the wool production of the ewes, and is conducive to increasing the weight of the ewes in the next year, wherein:

[0074] Multiple births are the basis for high productivity and high yield in sheep farming. With the improvement of breeding level, the number of twin lambs of single-birth Ordos Albas white cashmere goats has gradually increased, but it is still in a low reproductive rate status and cannot meet the market demand for white cashmere goat wool and high-quality mutton. The present invention is used for white cashmere goats in grazing period. Before the white cashmere goats are mated, the nutritional status of grazing sheep is improved before and after mating, and the ovulation rate of Albas white cashmere goats is improved.

[0077] In the second aspect, the present invention supplements nutrition to the breeding ewes of the Albas type Inner Mongolian white cashmere goats in Ordos before and after mating, which can increase the birth weight of the lambs: birth weight is an indicator that affects the survival rate of lambs. The weight of the breeding ewes before and after mating not only affects the lambing rate, but also has an important impact on the birth weight of the fetus and the weight of the ewes in the following year. The present invention supplements the Inner Mongolian cashmere goats with the concentrate supplement of the present invention for 60 days before and after mating, and the other times are the same as the feeding and management of the control group. After supplementary feeding, the birth weight of single lambs after lambing is increased by about 0.24kg and 0.33kg, and there is no obvious change in twin lambs.

[0078] On the third aspect, the present invention supplements nutrition to the breeding ewes of the Albas-type Inner Mongolian white cashmere goats in Ordos before and after mating, which can increase the wool production and the weight of the ewes in the next year: in the textile industry, the wool production reflects the importance of wool quality, and the higher the wool production, the better the product quality. Wool production is related to the nutritional level, and nutritional imbalance or deficiency can reduce wool production. The wool production of the ewes in the experimental group of the present invention has increased, and the experimental group 2 has increased by about 0.15kg compared with the control group, and the weight after fleecing has also increased.

[0079] In the fourth aspect, the protein content of Artemisia sphaerocephala meal is 52.19%, and it contains 4.47% crude fat and polyphenols. Its protein quality is higher than that of soybean meal protein. Artemisia sphaerocephala oil is rich in unsaturated fatty acids, VE and polyphenols, of which unsaturated fatty acids are as high as 91%, vitamin content is 1.5%-2%, (VE content is 1.12%), polyphenols are 3-5%, and it also contains compounds of mineral elements such as phosphorus, calcium, and iron. Because the fat content of this formula feed is relatively high, and the VE and polyphenols in Artemisia sphaerocephala oil and polyphenols in Artemisia sphaerocephala meal have the function of scavenging free radicals and inhibiting lipid peroxidation, which can effectively prevent the oxidation of vegetable oil and be fully absorbed and utilized by the body, solving the negative energy balance while reducing follicular atresia and increasing the number of mature follicles discharged. At the same time, the polyphenols contained in Artemisia oil have antibacterial and anti-inflammatory effects, which can effectively reduce gastroenteritis in maternal animals and adjust gastrointestinal function, thereby increasing feed intake, improving the overall body condition of cashmere goats, ensuring conception rate, lamb birth weight and survival rate, and ultimately increasing the lamb birth rate and survival rate of cashmere goats.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
