Embodiment Construction

[0013] In this experiment, a single factor design was adopted, and 100 LY sows of parity (3-4 parity) and similar body weight were selected and randomly divided into 5 treatments, each treatment had 20 replicates, and each replicate had one pig. The sows were fed the experimental diets of each treatment from the day of farrowing until the piglets were weaned on day 21.

[0014] No feed on the day of delivery, 1 kg of lactation feed on the first day after delivery, and then increase by 0.5-1.0 kg per day, so that the sows can reach the maximum feed intake of 5-6 kg after 7 days, after which the sows can eat and drink freely. Clean and disinfect the pigsty regularly according to the routine cleaning and disinfection system of the pig farm, and ensure that the house is clean and dry, well ventilated, and at a suitable temperature.

[0015] The ration was formulated with reference to the nutritional requirements recommended by NRC (2012), and with reference to the national feeding...

Abstract

The invention discloses a feed additive for improving the production performance of lactating sows, and a feed. The additive is prepared from the following raw materials in parts by weight: 2-5 parts of cholecystokinin (CCK) antibody containing eggyolk powder, 1-3 parts of soy isoflavone and 15-40 parts of valine. The feed is prepared from the following components in percentage by weight: 0.02-0.05 percent of CCK antibody containing eggyolk powder, 0.01-0.03 percent of soy isoflavone and 0.15-0.4 percent of valine. The feed for lactating sows can be used for remarkably improving the production performance of lactating sows, improving milk composition and improving milk quality by jointly adding the CCK antibody containing eggyolk powder, the soy isoflavone and the valine.

Description

technical field [0001] The invention belongs to the field of animal feed, and relates to a feed additive and feed for improving the production performance of lactating sows. Background technique [0002] PSY is the number of weaned piglets provided by each sow per year. It is the most important indicator to measure the production performance of sows and directly affects the economic benefits of large-scale pig farms. The survival rate of lactating piglets is one of the most important factors affecting PSY. In countries with developed pig farming such as Denmark, the survival rate of lactating piglets is as high as 95%. According to the statistics of a large number of pig farms in my country in 2014, this The data is around 75%, about 20% lower than the foreign advanced level. The survival rate of piglets during lactation is directly related to the milk quantity and quality of sows. At the same time, the better the milk quality, the greater the weaning weight of piglets, and ...
