Embodiment example 1

[0021] The preparation ratio according to the components is (content per liter of solution): 40g of lysine, 15g of methionine, 8g of tryptophan, 20g of threonine, 20g of valine, 15g of histidine, 20g of arginine, 40g of glycine, Histidine 10g, glutamic acid 40g, vitamin B 1 15g, vitamin B 2 15g, vitamin B 12 10g.

[0022] The above components were dissolved in 1000ML distilled water, and a feeding test was carried out in a large-scale breeding enterprise in Sichuan. In the experiment, 200 LY weaned sows with parity 3-5 were selected, and they were equally divided into two treatment groups according to body weight, with 100 sows in each treatment group. The weaned sows in the control group ingested 30ML of blank distilled water every day, and the weaned sows in the treatment group ingested 30ML of the drinking water of the present invention every day. The test began immediately after weaning, and the sows were identified for estrus, so that the vulva was red and swollen and ...

[0024] The preparation ratio according to the components is (content per liter of solution): 40g of lysine, 15g of methionine, 8g of tryptophan, 20g of threonine, 20g of valine, 15g of histidine, 20g of arginine, 40g of glycine, Histidine 10g, glutamic acid 40g, vitamin B 1 15g, vitamin B 2 15g, vitamin B 12 10g.

[0025] The above components were dissolved in 1000ML distilled water, and a feeding test was carried out in a large-scale breeding enterprise in Guangxi. In the experiment, 200 LY weaned sows with parity 1-2 were selected, and were equally distributed to two treatment groups according to body weight, with 100 sows in each treatment group. The weaned sows in the control group ingested 25ML blank distilled water every day, and the weaned sows in the treatment group ingested 25ML of the drinking water solution of the present invention every day. The test began immediately after weaning, and the sows were identified for estrus, so that the vulva was red and swollen a...

Abstract

The invention discloses drinking liquid for increasing estrus rate of weaning sows and application thereof. Each L of the drinking liquid contains 20-40 g of lysine, 10-20 g of methionine, 4-10 g of tryptophan, 10-20 g of threonine, 10-20 g of valine, 10-15 g of histidine, 10-20 g of arginine, 20-40 g of glycine, 5-10 g of histidine, 20-40 g of glutamic acid, 5-15 g of vitamin B1, 5-15 g of vitamin B2, and 5-10 g of vitamin B12. All the amino acids and vitamins are of food grade, and solution is obtained by preparing in a scientific way. The drinking liquid is high in safety; post-weaning estrus rate of the weaning sows feeding on 30-50 ML of the liquid each day can be increased significantly, false pregnancy period of the sows is decreased, and conception rate is increased.

Description

technical field [0001] The invention relates to the technical field of animal health products, in particular to a drinking liquid for improving the estrus rate of weaned sows and an application thereof. Background technique [0002] Actual production of weaned sows has a delayed or failed estrus ratio of up to 30%, which not only increases the culling rate of sows, but also directly affects the lifelong reproductive performance of sows. Poor management of large-scale pig farms, disease pressure, and nutritional imbalance are the key factors that lead to insufficient secretion of insulin-like growth factor 1 in blood of weaned sows, which leads to delayed estrus or failure of estrus. [0003] Patent 201110039174.5 discloses a post-weaning aphrodisiac supplementary feed for sows, mainly composed of 20-40% wheat bran, 25-35% corn, 5-15% corn bran, 5-5% corn DDGS, and 0-15% glucose , soybean meal 3-9%, stone powder 1-2%, calcium hydrogen phosphate 1-2%, corn oil 0-0.5%, salt 0....
