Problems solved by technology

[0002] At present, the main way of producing cashmere goats is house feeding. Compared with grazing or semi house feeding, the cashmere goats raised in house feeding have fewer types of feed and less exercise. They are generally raised in separate pens with rams during production. The stimulating effect of rams on ewes is reduced, resulting in insignificant estrus and ovulation effects of house-feeding ewes, low pregnancy rate in one mating, and low overall reproductive survival rate, etc.

Embodiment 1

[0018] In the present embodiment, Astragalus accounts for 13.33% of the total weight, Eucommia accounts for 13.33% of the total weight, Epimedium accounts for 11.12% of the total weight, Cuscuta accounts for 8.89% of the total weight, Scutellaria baicalensis accounts for 11.11% of the total weight, and Fructus Lycium barbarum accounts for 11.11% of the total weight. 8.89% by weight, methionine chelated manganese accounts for 0.67% of the total weight, rumen-passed glucose accounts for 22.22% of the total weight, rumen-passed vitamin E accounts for 0.23% of the total weight, and auxiliary materials (cornmeal) account for 10.21% of the total weight.

[0019] The preparation method comprises the following steps: selecting high-quality Chinese medicine decoction pieces astragalus, angelica, epimedium, dodder, scutellaria baicalensis and medlar, respectively drying in an oven until the water content is less than 0.5 percent, then crushing them with a pulverizer and passing through a ...

Embodiment 2

[0021] Weigh 11.7% of astragalus, 11% of Eucommia, 9% of epimedium, 7% of dodder, 14% of scutellaria, and 11% of wolfberry in an oven at 60°C until the water content is less than 0.5% %, and then crushed to 40 mesh sieves with a pulverizer and mixed to form premix A; Weighed 1% methionine chelated manganese, 20% rumen-passed glucose, 0.3% rumen-passed vitamin E and 15% rumen-passed vitamin E % cornmeal is mixed uniformly to form premix B; premix A is mixed with premix B evenly. Use aluminized matt aluminum foil bags inside, seal and store in a cool place at 4°C.

Embodiment 3

[0023] Weigh 15% astragalus, 16% Eucommia, 10.5% epimedium, 10% dodder, 11% scutellaria, and 6% medlar in an oven at 80°C until the water content is less than 0.5% %, and then pulverized into a 40 mesh sieve with a pulverizer and mixed to form premix A; Weighed 0.4% methionine chelated manganese, 22% rumen-passed glucose, 0.1% rumen-passed vitamin E and 9 % cornmeal is mixed uniformly to form premix B; premix A is mixed with premix B evenly. Use aluminized and matte aluminum foil bags inside, seal and store in a cool place at 15°C.

Abstract

The invention discloses a compound feed additive for improving the reproductive performance of a cashmere she-goat and a preparation method, and belongs to the field of feed. The compound feed additive comprises the following raw materials in percentage by mass of 10%-15% of radix astragali, 11%-16% of cortex eucommiae, 9%-12% of herba epimedii, 7%-10% of semen cuscutae, 11%-14% of radix scutellariae, 6%-11% of fructus lycii, 0.4%-1.2% of manganese methionine chelate, 20%-26% of rumen bypass glucose, 0.1%-0.3% of rumen bypass vitamin E and 9%-15% of corn flour. The additive can regulate the hormone secretion level of the barn-fed cashmere she-goat, promote estrus and ovulation of the she-goat, improve the breeding pregnancy rate and the lambing rate of the she-goat and reduce the nonpregnant rate of the barn-fed she-goat, so that the reproductive performance of the she-goat is improved.

technical field [0001] The invention belongs to the field of feed, and in particular relates to a compound feed additive for improving the reproductive performance of cashmere goat ewes and a preparation method thereof. Background technique [0002] At present, the main way of producing cashmere goats is house feeding. Compared with grazing or semi house feeding, the cashmere goats raised in house feeding have fewer types of feed and less exercise. They are generally raised in separate pens with rams during production. The stimulating effect of the rams on the ewes is reduced, resulting in insignificant estrus and ovulation effects of the house-feeding ewes, a low pregnancy rate in one mating, and a low overall reproductive survival rate. Contents of the invention [0003] In view of the above deficiencies, the present invention provides a compound feed additive for improving the reproductive performance of cashmere goat ewes. The additive can regulate the hormone secretio...
