Description

Technical Field

[0001] The present invention relates to the technical field of animal breeding feeds, and specifically relates to a nutritional feed for Albas white cashmere goats and a preparation method thereof. Background Art

[0002] Mutton is one of the three major meat foods. Mutton has a high protein content and a low fat content, so it tastes delicious and is loved by people. In particular, Albas white cashmere goats enjoy the reputation of "ginseng in meat". Mutton is rich in protein, trace elements, and its amino acid composition is closer to the human body's needs than that of pork and beef, and can improve the body's disease resistance.

[0003] With the continuous improvement of people's living standards, the demand for mutton is increasing, which has also driven the development of the sheep breeding industry. However, during the process of raising sheep, it is found that their weight gain is relatively slow. Especially for the sheep in the fattening period, their weight gain is slow and the meat yield is poor, resulting in a long feeding time and high cost. Summary of the Invention

[0051] The preparation method of the present invention includes pressing pellets, which is more convenient for storage, easier for sheep to eat and absorb than traditional forage, mixed forage and other raw feeds.

[0052] Among the raw materials of the present invention, corn, corn grass, alfalfa, caragana, salix psammophila, natural wildrye grass, etc. are common or artificially cultivated woody plants and herbaceous plants.

[0053] Among the raw materials of the present invention, celery, salix psammophila, pumpkin, white radish, etc. are high-quality vegetables.

[0054] In the method of the present invention, corn, corn grass, alfalfa, caragana, salix psammophila, and natural Chinese wildrye (when included) are crushed into powder.

[0055] In the method of the present invention, celery, allium mongolicum, pumpkin, and white radish are cut into segments.

[0056] In the method of the present invention, after all raw materials are crushed or cut into segments, they are fully mixed and then pressed. There is no addition of chemical substances. This feed is nutritionally comprehensive and is especially suitable for fattening sheep. It can increase the daily weight gain and meat yield of sheep, and is beneficial to reducing the breeding time and economic cost of sheep.

[0057] The vegetables provided by the present invention can improve the appetite of sheep, strengthen the physique of sheep, and greatly reduce the morbidity and mortality.

[0058] In various embodiments of the present invention, the sheep nutritional feed of the present invention has obvious improvements in the growth of sheep, and the weight gain and meat quality are obvious. When one or two components are lacking, the weight gain effect of the feed becomes worse.

[0059] In various embodiments of the present invention, the sheep nutritional feed of the present invention significantly improves the cashmere quality. After feeding with the sheep nutritional feed of the present invention, the cashmere yield increases, the color of the sheep's wool is snow-white, the gloss is good, it is soft and delicate, and the hand feeling is comfortable.

[0061] Compared with 14.5 μm, if the diameter is too thick, it will become hard and the comfort level will decrease.

[0062] Compared with 38 mm, if the length is too short, it is not conducive to spinning.

[0063] In various embodiments of the present invention, after feeding with the sheep nutritional feed of the present invention, various trace elements beneficial to the human body such as protein, amino acids, and iron in the mutton increase significantly, the meat quality is more tender, there is an obvious grassy fragrance when eaten, there is no mutton smell of general breed goats, and the taste is mellow and delicious, with a unique flavor.

[0064] In particular, an embodiment containing 10 - 18 parts by weight of corn grass, 10 - 18 parts by weight of corn, 10 - 18 parts by weight of Caragana korshinskii, 10 - 18 parts by weight of Salix psammophila, 2 - 6 parts by weight of Allium mongolicum, 10 - 15 parts by weight of pumpkin, 10 - 15 parts by weight of white radish, 2 - 6 parts by weight of sodium bicarbonate, 1 - 3 parts by weight of sodium chloride, and 2 - 6 parts by weight of Zizania caduciflora, and more particularly an embodiment containing 15 parts by weight of corn grass, 15 parts by weight of corn, 15 parts by weight of Caragana korshinskii, 15 parts by weight of Salix psammophila, 4 parts by weight of Allium mongolicum, 13 parts by weight of pumpkin, 13 parts by weight of white radish, 5 parts by weight of sodium bicarbonate, 2 parts by weight of sodium chloride, and 3 parts by weight of Zizania caduciflora, achieves the optimal meat quality of Albas Cashmere Goats, with the protein, amino acid, and iron contents all reaching the best levels.

[0080] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1.

[0081] Comparative Example 1

[0082] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1, except that Sagittaria pygmaea is not included.

[0083] Comparative Example 2

[0084] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1, except that Salix psammophila is not included.

[0085] Comparative Example 3

[0086] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1, except that Allium mongolicum is not included.

[0087] Comparative Example 4

[0088] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1, except that Sagittaria pygmaea and Salix psammophila are not included.

[0089] Comparative Example 5

[0090] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1, except that white radish is not included.

[0091] Comparative Example 6

[0092] Prepare cylindrical pellet feeds about 3 cm in length and 1 cm in diameter in a manner similar to that of Example 1, except that Caragana korshinskii is not included.

[0093] After the above Examples 1 - 4 and Comparative Examples 1 - 6 are prepared, experiments are conducted through comparative feeding.

[0094] 70 Albas white cashmere goats, all 1 year old, were divided into 10 groups, with 7 goats in each group. The 10 groups were fed with the feeds of Examples 1 - 4 and Comparative Examples 1 - 6 respectively, and the average results of the 7 goats in each group were recorded. The results are shown in Table 1.

[0095] The goats in the fattening period were given feed. The fattening period was 90 days. The growth performance of the goats before and after the fattening period was tested. The main growth performances tested were the initial weight, the weight at the end of the test, and the average daily gain.

[0096] Table 1 Experimental results of weight gain and cashmere quality of each example and comparative example

[0097]

[0098] As can be seen from the above experimental examples shown in Table 1, the feed prepared by the present invention has obvious improvements in the growth of goats. The most obvious improvement in weight gain and meat quality is in Example 4. In addition, from Comparative Examples 1 - 6, it can be seen that the feed without one or two components of the present invention results in poor weight gain.

[0099] As shown in Table 1, the cashmere quality of Examples 1 - 4 is significantly improved. Among them, the A - grade cashmere quality evaluation is: the cashmere yield increases, the cashmere color of the goats is snow - white, with good gloss, soft and delicate, and comfortable to the touch. The B - grade is that there are 1 - 2 items among the cashmere yield, cashmere color, gloss, softness, and touch that are poor. The C - grade is that there are 3 - 4 items among the cashmere yield, cashmere color, gloss, softness, and touch that are poor.

[0100] In addition, from Comparative Examples 1 - 6, it can be seen that the feed without one or two components of the present invention results in poor improvement in cashmere quality.

[0101] The indicators reflecting the cashmere quality are diameter and length. According to its special hair structure, for Albas white cashmere goats, the best performance is achieved when the wool diameter is ≤14.5μm and the length is ≥38mm (GB 18267 - 2013).

[0102] For each of the 7 animals in each example, 10 hairs were taken respectively. That is, a total of 70 hairs were taken for each example. After measuring the diameter and length and taking the average value, the results are shown in Table 2. It can be seen that the wool diameter of Examples 1 - 4 is close to 14.5μm, while the wool diameter of Comparative Examples 1 - 6 becomes larger and deviates far from the maximum wool diameter of 14.5μm specified in GB 18267 - 2013 compared with the examples. It can be seen that the wool length of Examples 1 - 4 is 66.8 - 71.2mm, while the wool length of Comparative Examples 1 - 6 is 43.3 - 53.5mm. The wool length of Examples 1 - 4 is longer than that of Comparative Examples 1 - 6. Therefore, the wool performance of Examples 1 - 4 is better than that of Comparative Examples 1 - 6.

[0103] Table 2 Wool diameter and length of each example and comparative example

[0104]

[0105]

[0106] In addition, through the slaughter of Experimental Examples 1-4 (average results of 7 animals in each example), it was found after testing that the content of various components beneficial to the human body, such as protein, amino acids, fatty acids, and iron content, which are rich in the mutton of the examples, increased significantly (the results are shown in Table 3 below). The meat quality is more tender, with an obvious grassy aroma when eaten, without the muttony smell of ordinary breeds of mountain goats, and the taste is mellow and delicious, with a unique flavor. The drip loss of the mutton in Experimental Examples 1-4 is small, and the chewiness is significantly better than that of Comparative Examples 1-6.

[0107] The muttony smell of the mountain goats in Comparative Examples 1-6 fed with feeds that do not have one or two components of the present invention is obvious.

[0108] Especially in Example 3, the optimal meat quality of Albas white cashmere goats was achieved, and its protein, amino acids, fatty acids, iron content, drip loss, and chewiness all reached the best level.

[0109] Table 3 Evaluation results of mutton in each example and comparative example

[0110]

[0111]

[0112] In summary, when the feed of the present invention is used for feeding, it has a better weight gain effect on sheep, better cashmere quality, the cashmere diameter and length meet the national standard (GB 18267-2013) for superfine type, the protein, amino acids, fatty acids, and iron content in the meat are high, and the drip loss and chewiness are excellent.

[0113] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
