Problems solved by technology

[0002] After sows are mated and pregnant, mammary gland tissue begins to develop, and mammary gland tissue begins to replace fat tissue, especially after 70 days of gestation, it develops rapidly until the sow is weaned. However, in recent years, with the excessive selection of lean meat breeds, The estrogen in the sow is suppressed, and the mammary gland development is seriously affected. Some sows have flat mammary glands in the late pregnancy, and the milk supply is seriously insufficient after delivery, resulting in diarrhea and low weaning weight in piglets. Some piglets even have no milk to eat, and the mortality rate remains high. Serious Affect the production performance and breeding benefits of the farm
Therefore, in order to achieve high-efficiency production results, how to promote the normal metabolism of estrogen in sows by means of nutritional technology, how to promote the good development of sow mammary gland tissue and the normal start of lactation function are of vital significance. There is also a lack of targeted nutritional technical measures

Embodiment 1

[0014] A nutritional feed additive for promoting mammary gland development in sows, consisting of the following components in parts by weight

[0015] Papaya powder: 15kg, expanded soybean powder: 75kg, organic selenium: 5kg, vitamin E: 5kg

[0016] In order to verify the promotion effect of the present invention on the mammary gland development of sows in late pregnancy, the present invention has carried out multiple repeated feeding experiments in 6 pig farms including Guangxi, Guangdong, Sichuan, and Hunan, and the test time is from 70 days of pregnancy to delivery of sows. Using a single-factor comparative test design, 100 healthy pregnant sows with the same parity, similar body weight, and similar gestation period (about 70 days of gestation) were randomly divided into a test group and a control group, with 50 pigs in each group. The diet of the control group is high-grade feed for pregnant sows in the market, and the diet of the test group is added with 0.3% of the produ...

Embodiment 2

[0021] A nutritional feed additive for promoting mammary gland development in sows, consisting of the following components in parts by weight

[0022] Papaya powder: 10kg, expanded soybean powder: 50kg, organic selenium: 4kg, vitamin E: 4kg

[0023] In order to verify the promotion effect of the present invention on mammary gland development of lactating sows, the present invention has carried out multiple repeated feeding experiments in 8 pig farms including Guangliang, Guangdong, Sichuan, and Hunan. Using a single-factor comparative test design, healthy farrowing sows are randomly divided into a test group and a control group. The diet of the control group is high-grade lactating sow feed in the market, and 0.3% of the product of the present invention is added to the diet of the control group. .

[0024] The pros and cons of mammary gland development of lactating sows are defined as normal if the sow’s breasts are contoured, and abnormal as flat.

Abstract

The invention discloses a nutritive feed additive capable of promoting the development of mammary gland of sows. The nutritive feed additive comprises the following components in parts by weight: 10-25 parts of papaya powder, 20-100 parts of expanded soybean meal, 1-5 parts of organic selenium and 3-10 parts of vitamin E. The nutritive feed additive disclosed by the invention is capable of promoting the normal metabolism of female hormones of the sows, further promoting the good development of mammary gland tissues of the sows and the normal start of a lactation function and increasing the productivity effect of livestock farms.
