Composite premixed fodder for replacement gilts and feeding method of fodder

Abstract

The invention discloses a composite premixed fodder for replacement gilts and a feeding method of the fodder. The composite premixed fodder comprises the following components in percentage by weight: 2-3.7 percent of a trace element premixed fodder, 7.5-12.5 percent of edible salt, 20-35 percent of calcium hydrophosphate, 20-35 percent of mountain flour, 5-12.5 percent of lysine, 1-3 percent of methionine, 2.5-5 percent of threonine and 20-50 percent of a carrier, wherein the trace element premixed fodder contains the copper element, the iron element, the zinc element, the manganese element, the selenium element and the iodine element. The composite premixed fodder for the replacement gilts contains various trace elements and mineral substances, and the composite premixed fodder is mixed with corn, wheat brans and soya bean meal in a certain proportion to form a complete feed for the replacement gilts; according to the feeding method of the fodder, healthy growth of reproductive organs of the gilts can be promoted, coordinative growth of bones and muscles can be promoted, and the reproduction parity of the gilts can be increased.

Description

technical field [0001] The invention belongs to the technical field of feeding feed specially suitable for animals, and in particular relates to a compound premixed feed for gilts and a feeding method thereof. Background technique [0002] Due to the humid air, abundant precipitation, weak solar radiation, short sunshine time, and cloudy fog in the southwestern region, problems such as slow start of estrus in gilts, low breeding rate, and the occurrence of second-born sow syndrome in pig farms are serious. The interests of pig farmers are restricted. In addition, many feeds that appear on the existing market only focus on energy and protein for gilts. The purpose is to rapidly increase the growth of gilts, resulting in low lean meat percentage of pork and poor muscle quality. The shortcomings of low fat, low litter, poor taste and low nutritional value of pork have seriously affected the reproductive value of gilts. The main reason is that gilts lack a variety of trace eleme...

Problems solved by technology

[0002] Due to the humid air, abundant precipitation, weak solar radiation, short sunshine time, and cloudy fog in the southwestern region, problems such as slow start of estrus in gilts, low breeding rate, and the occurrence of second-born sow syndrome in pig farms are serious. The interests of pig farmers are restricted. In addition, many feeds that appear on the existing market only focus on energy and protein for gilts. The purpose is to rapidly increase the growth of gilts, resulting in low lean meat percentage of pork and poor muscle quality. The shortcomings of low fat, low litter, poor pork taste and low nutritional value have seriously affected the reproductive value of gilts. The main reason is that gilts lack a variety of trace elements or trace elements are seriously exceeded
