Description

Technical Field

[0001] This invention belongs to the field of feed, and specifically relates to a traditional Chinese medicine feed additive suitable for sows. Background Technology

[0002] Postpartum sows are prone to mastitis during lactation, often experiencing loss of appetite and insufficient milk production, which hinders postpartum recovery and negatively impacts piglet growth. The quality of sow milk is a crucial factor directly related to piglet health. Insufficient milk production and mastitis leading to poor milk quality increase piglet morbidity, resulting in weaker piglets that struggle to reach their expected weight within the predetermined timeframe. Furthermore, a weak and sickly sow hinders postpartum recovery. To promote timely recovery, shorten the estrus cycle, and improve economic efficiency, additives are needed in sow feed to increase appetite, accelerate postpartum recovery, increase milk production, and enhance piglet immunity, thereby improving survival rates and promoting growth and development. Summary of the Invention

[0003] To address the above technical problems, this invention discloses a traditional Chinese medicine feed additive suitable for sows.

[0004] A herbal feed additive suitable for sows includes Formula 1 and Formula 2. Formula 1 includes Fructus Aurantii Immaturus, Roasted Atractylodes macrocephala, Salvia miltiorrhiza, Astragalus membranaceus, Roasted Shenqu (medicated leaven), Glycyrrhiza uralensis, Vaccaria segetalis, and Akebia trifoliata. Formula 2 includes Astragalus membranaceus, Cistanche deserticola, Epimedium brevicornu, Ligustrum lucidum, Angelica sinensis, Codonopsis pilosula, Roasted Atractylodes macrocephala, Poria cocos, and Roasted Shenqu (medicated leaven).

[0005] In a further improvement, the mass ratio of Fructus Aurantii Immaturus, Rhizoma Atractylodis Macrocephalae, Radix Salviae Miltiorrhizae, Radix Astragali, Rhizoma Massa Fermentatae, Radix Glycyrrhizae, Semen Vaccariae, and Radix Akebiae Mukorossi in Formula 1 is 6:12:15:15:15:6:20:15.

[0006] In a further improvement, the mass ratio of Astragalus membranaceus, Cistanche deserticola, Epimedium brevicornu, Ligustrum lucidum, Angelica sinensis, Codonopsis pilosula, stir-fried Atractylodes macrocephala, Poria cocos, and charred Shenqu in Formula 2 is 15:15:15:12:12:15:15:12:15.

[0007] As a further improvement, the addition amount of both Formula 1 and Formula 2 is 2% of the total weight of the basal diet.

[0008] Further improvements include Formula 1, which is used as feed for sows on days 1-10 after piglets are born, and Formula 2, which is used as feed for sows on days 11-20 after piglets are born.

[0009] The beneficial effects of this invention are as follows: 1. Formula 1 of this invention can promote digestion in sows and facilitate menstruation and lactation. 2. Formula 2 of this invention can promote postpartum recovery in sows, shorten the estrous cycle, enhance immunity, and reduce the incidence of mastitis. 3. When Formula 1 and Formula 2 are used together, they have a better synergistic effect. Detailed Implementation

[0010] The embodiments of the present invention will be further described below with reference to examples. It should be noted that the examples do not constitute a limitation on the scope of protection of the present invention.

[0011] 1. Medicinal materials and their processing in the experiment The Chinese herbal medicine pieces used in the experiment were dried to a moisture content of less than 7%, and then pulverized to a particle size of 120 mesh for later use.

[0012] 2. Experimental basal diet and its nutrient levels The basal diet and its nutritional level for the sows used in the experiment were formulated with corn-soybean meal as the basis for the nutritional requirements of pigs according to the US NRC (2012) standards, and were produced by Hunan Baodong Agricultural and Animal Husbandry Co., Ltd.

[0013] 3. Selection of Traditional Chinese Medicine Feed Additive Formulation Based on the functions of commonly used Chinese medicines, the basic principles of Chinese medicine compatibility, the composition of Chinese veterinary prescriptions, and referring to previous research results and the market prices of Chinese medicinal materials, two formulas for sow feed additives were developed. The proportion of Chinese medicinal materials in the formulas was determined with reference to human medication dosages, and the mixed powder of the formulas accounted for 2% of the total weight of the basic daily ration.

[0014] (1) Formula 1: Promotes digestion in sows and promotes menstruation and lactation.

[0015] 6 kg of immature bitter orange, 12 kg of stir-fried atractylodes macrocephala, 15 kg of salvia miltiorrhiza, 15 kg of astragalus membranaceus, 15 kg of charred medicated leaven, 6 kg of licorice, 20 kg of vaccaria segetalis and 15 kg of akebia quinata are dried to a moisture content of less than 7%, pulverized into 120-mesh powder and mixed together. This mixture is used to promote digestion, menstruation and lactation in sows.

[0016] (2) Formula 2: Promotes postpartum recovery in sows, shortens the estrus cycle; enhances immunity and reduces the incidence of mastitis. 15 kg of Astragalus membranaceus, 15 kg of Cistanche deserticola, 15 kg of Epimedium brevicornu, 12 kg of Ligustrum lucidum, 12 kg of Angelica sinensis, 15 kg of Codonopsis pilosula, 15 kg of stir-fried Atractylodes macrocephala, 12 kg of Poria cocos, and 15 kg of charred Shenqu were dried to a moisture content of less than 7%, pulverized into 120-mesh powder, and mixed together. This mixture is used to promote postpartum recovery in sows, shorten the estrus cycle, enhance immunity, and reduce the incidence of mastitis.

[0017] 4. Experimental Design and Grouping The experiment selected 120 farrowing sows, with 12 sows in each group. They were divided into 5 groups according to similar weight and parity, with 2 replicates in each group and each replicate in a separate column. The entire experiment lasted for 20 days.

[0018] A. Blank control group (basal diet); B. Experimental group 1 (basal diet + formula 1); C. Experimental group 2 (basal diet + formula 2); D. Experimental group 3 (basal diet + formula 1 (first 10 days) + formula 3 (11-20 days)).

[0019] 5. Feeding and Management The feeding trial was conducted in a fully enclosed pigsty with free access to water and feed. The pigsty had good ventilation, and the indoor humidity was controlled at around 78%; the room temperature was kept stable at 25℃.

[0020] 6. Detection Indicators The following indicators were tested in sows: Table 1. Average daily milk production, average estrus rate, and incidence of mastitis in sows. project Group A Group B Group C Group D Average daily milk production (kg) 5.62 9.17 6.17 11.26 Average estrus rate 40% 45% 70% 85% Incidence of mastitis 6.99% 2.81% 1.61% 0.34% Mastitis incidence rate = (Number of sows with mastitis * Number of days with mastitis) / (Total number of sows * Number of days of feeding)

[0021] It is evident that both formulations of this invention can increase milk production, but formulation one is more effective, while formulation two can significantly increase the estrus rate of sows and reduce the incidence of mastitis. However, the combined use of formulations one and two yields the best results.

[0022] The following are the indicators for piglets raised by sows: Table 2. Weight, feed consumption, daily weight gain, daily feed intake, and feed conversion ratio of piglets. project Group A Group B Group C Group D Initial weight (kg) 6.12±1.13 6.13±1.05 6.11±1.26 6.12±1.15 Final weight (kg) 9.43±2.15 9.70±2.26 9.85±2.18 10.01±2.19 1-10 days Average daily weight gain (g) 331±14.27 357±8.75 374±12.16 389±10.63 Average daily feed intake (g) 547±14.05 582±9.26 574±12.37 585±11.45 Weight gain ratio 0.62±0.02 0.62±0.02 0.63±0.02 0.62±0.02 Diarrhea rate (%) 6.56±1.24 3.45±1.57 1.97±1.47 1.09±0.43 10-20 days Average daily weight gain (g) 427±3.73 454±6.25 443±12.27 458±6.03 Average daily feed intake (g) 847±16.54 901±10.76 893±11.18 900±9.27 Weight gain ratio 0.51±0.01 0.50±0.01 0.50±0.01 0.50±0.01 Diarrhea rate (%) 1.87±1.13 0.95±0.86 0.47±0.15 0.15±0.23

[0023] The above demonstrates that the formulation of this invention can improve the daily weight gain of piglets and reduce their diarrhea rate by increasing the quality of sow's milk, and the effect is significantly better when the two formulations are used simultaneously.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
