Embodiment 1

[0014] In a large pig farm in Hebei Province. From the 90th day of gestation of sows to the end of weaning of piglets (28 days), a total of 52 days.

[0015] A total of 24 healthy sows of the same breed and with similar litter performance were selected and randomly divided into 2 treatment groups, with 12 replicates in each treatment group and 1 sow in each replicate. The control group is the diet of a certain company, and the test group is the formula diet of the invention. See Table 1 for formula and nutritional level of lactating pig feed of the present invention.

Abstract

The invention discloses a lactating sow feed, comprising the following components in parts by weight: 50-70 parts of corns, 5-15 parts of wheat bran, 10-27 parts of bean pulp, 0.3-1.8 parts of calcium hydrogen phosphate, 1.0-1.5 parts of limestone powder, 0.2-0.5 part of salt and 1-2 parts of premix. 1kg of premix contains 23g of ferrous sulfate monohydrate, 1.8g of copper sulfate pentahydrate, 12g of zinc sulfate monohydrate, 2.5g of manganese sulfate monohydrate, 1.2g of calcium iodate, 0.9g of sodium selenite, 300g of sodium butyrate, 900mg of nicotinic acid, 400mg of VA, 40mg of VD, 1100mg of VE, 180mg of VK, 90mg of B1, 320mg of riboflavin, 130mg of VB12, 1300mg of pantothenic acid, 50mg of folic acid, 450mg of biotin and 653.64g of zeolite powder. By reasonably matching nutrients, the feed used for feeding normal healthy lactating sows in pig farms can realize nutrient balance, the weights of 28-day-old individual weaned pigs reach 9.6kg or more and are improved by about 1kg compared with the weights of the existing 28-day-old weaned pigs, and the marketing time of fat pigs is shortened.

Description

technical field [0001] The invention relates to a feed for livestock, in particular to a feed for lactating sows, and belongs to the technical field of feed processing. Background technique [0002] In the breeding technology of pigs, the weaning weight of piglets is an important factor in determining the age at which fattening pigs reach 100 kg. For every 1 kg increase in weaning weight at 28 days, the age at 100 kg at slaughter is shortened by about 10 days, and the weaning weight is the main factor. It determines the lactating power of lactating sows, and feed is a key factor in determining the lactating power. At present, due to the technical level of feed nutrition, the weaning weight is far below the weight that pigs can achieve. Most 28-day-old weaning individuals weigh less than 8.5kg, which prolongs the age of fattening pigs and affects the economic benefits of pig breeding. In the prior art, many measures are taken at the stage of fattening pigs, such as nutrition...
