Description

A kind of milking sow mixed feed

Technical field

The invention belongs to the fodder compound field, relate to a kind of composition that is used to promote the sow lactation particularly.

Background technology

How to let the healthy healthy and strong growth of a brood of piglet about 10; Obtain best health status and maximum weanling weight; Be the key that milking sow is raised, what we must take into account simultaneously certainly is body storage loss and the health status of milking sow self, and the interval of how to shorten ensuing wean-oestrus; After breeding cycle show continuable good reproductive performance, and prolong the reproductive life.The key that addresses the above problem is to improve the feed intake of milking sow, and this equally also is to raise the maximum bottleneck of milking sow.Modern genotypic sow has better reproductive performance, but appetite is but very low.Therefore the key technology of the raising of milking sow is exactly how to maximize its feed intake, and the daily ration of formulation science nutrition is have additional nutrients material particularly effective energy and amino acid whose absorption after all.

Number born of sow has had tangible increase in the past few years, almost is the twice in past 30 years.The sow output of milk is relevant with the suckling pig number, and in addition, average every piglet output of milk also increases when litter size increases, and both combinations have improved nutritional requirement.The nest weightening finish has also influenced the output of milk, can be very accurately through estimating the sow output of milk from birth to the piglet growth speed of wean.The output of milk makes sow increase energy and amino acid whose demand, if do not provide in the daily ration, sow will provide by consumer fat; 60% of body weight loss is an adipose tissue, and 40% is musculature, and the energy and the amino acid that so just need to take in high-load are used for the loss of the high output of milk to prevent that body fat from stocking.But the gene of high lean meat percentage pig cause sow pig to stock reduction in order to the body fat of keeping these additional demands; Brought new pressure simultaneously in order to improve food conversion ratio, nutrient is taken in not proportional with the increase of nutritional need, and actual conditions are that sow appetite reduces, and the feed intake descends.These factors are prepared economic high yield daily ration, are kept the high feed intake of sow and brought very big pressure to the nutritionist, and the problem that the latter faces is especially serious.

Summary of the invention

In order to solve problems such as milking sow lactation deficiency, postweaning estrus delay, the present invention seeks to let the wean sow through feeding N-carbamylglutamic acid and valine, promote the sow milking capacity, make it obtain bigger wean nest weightening finish.
