Embodiment 1

[0026] The weight ratio of the compound feed for improving the estrus rate of three-element gilts is: 55-65 parts of corn, 7-10 parts of soybean meal, 10-15 parts of fiber compound, 1-2 parts of soybean oil, 1-2 parts of corn starch 0.5-1 part of table salt, 1-2 parts of stone powder, 1-2 parts of calcium hydrogen phosphate, 0.3-0.5 part of lysine, 0.4-0.8 part of threonine, 1-2 parts of fermented Chinese herbal medicine, choline chloride 0.1 part, 0.02 part of antioxidant, 0.05 part of antifungal agent, 3 to 4 parts of compound premix for sows. In the process of compound feed preparation, the Chinese herbal medicine mixture is crushed and added to brown sugar water, mixed and stirred to form a uniform thick slurry; then the thick slurry is put into the mixed probiotic bacteria liquid composed of Saccharomyces cerevisiae, Bacillus subtilis and Lactobacillus coagulans. Primary fermentation; the weight ratio of the brown sugar water to the Chinese herbal medicine mixture is 100:...

Embodiment 2

[0035] The composition ratio and preparation of the compound feed are the same as in Example 1.

[0036] 1. Product feeding test: 120 sows with similar body weight, good health (no disease, similar fat condition), age of about 150±2.4 days, body weight of 85±3.5kg were selected for the test, grouped according to completely randomized areas, and divided into groups. There are 4 treatment groups, 6 repetitions in each group (one circle for each repetition), 5 pigs in each repetition, to ensure that the average parity of each treatment group is similar, the control group is pig farm feed, and the test group 1 is added with fermented Chinese herbal medicine , test group 2 added fiber compound, test group 3 added fiber compound+Chinese herbal medicine fermented product, the nutritional level of each group was basically the same (see Table 3), and the test ended when the sow puberty started (the first estrus);

[0037] 2. Feeding management: Feeding twice a day at 8:00 and 14:00, an...

Abstract

The invention discloses compound feed for improving the estrus rate of s Sanyuan replacement gilt. The compound feed comprises the following ingredients in parts by weight: 55-65 parts of corns, 7-10parts of soybean meal, 10-15 parts of fiber compounds, 1-2 parts of soybean oils, 1-2 parts of corn starches, 0.5-1 part of table salt, 1-2 parts of mountain flour, 1-2 parts of c calcium hydrogen phosphate, 0.3-0.5 part of lysine, 0.4-0.8 part of threonine, 1-2 parts of Chinese herbal medicine fermentation products, 0.1 part of choline chloride, 0.02 part of antioxidant, 0.05 part of mildew-proofagent and 3-4 parts of gilt compound premix materials. In the compound feed disclosed by the invention, key raw materials are subjected to fermentation and enzymolysis, nutrition is comprehensive, and the normal growth of the reproductive system of the Sanyuan replacement gilt can be guaranteed. Since the corn flour and the soybean oils are added, a ratio of energy from the starch and fat in feedenergy can be guaranteed, and triglyceride and total cholesterol concentrations in gilt blood can be improved so as to be favorable for puberty startup. Since a fiber compound is used for replacing bran, the secretion of insulin is accelerated so as to be favorable for the sex hormone secretion of the replacement gilt, the replacement gilt is accelerated to enter the estrus, the intestinal floraof the replacement gilt can be regulated, and the intestinal health of the replacement gilt can be maintained.

Description

technical field [0001] The invention relates to a compound feed for improving the estrus rate of three-element gilts. Background technique [0002] Due to the continuous occurrence and spread of African swine fever, my country's pig industry has suffered a heavy blow. Both the stock of live pigs and reproductive sows have dropped sharply, which has seriously affected the recovery of market pork supply and production capacity. In principle, ternary commercial sows are not suitable for breeding, but due to the impact of African swine fever, the stock of breeding pigs has dropped sharply, and because of safety concerns, many pig farms are afraid to introduce gilts from outside. Faced with the dilemma of having no breeds to introduce and no pigs to raise, many pig farms have to consider using ternary mixed sows (mostly "Du Dachang" ternary commercial sows) as breeding pigs to try to Restore the production capacity of hogs, which may become a normal situation in the next 2-3 yea...
