Granulated feed for gestation period of Xindan-series sows and preparation method of granulated feed

Abstract

The invention relates to a granulated feed for a gestation period of Xindan-series sows. The granulated feed contains the following components in parts by weight: 35-45 parts of cereals, 4-10 parts of bean pulp, 5-10 parts of rice bran, 5-10 parts of corn DDGS, 2-5 parts of puffed flaxseeds, 10-15 parts of wheat bran, 2-5 parts of soybean hulls, 1-3 parts of a peptide source, 1-3 parts of beet particles, 1-4 parts of oat bran, 0.5-3 parts of grease, 1-2 parts of mountain flour, 0.01-0.03 part of organic calcium HyD, 0.7-1.5 parts of calcium hydrogen phosphate, 0.1-0.3 part of table salt, 0.1-0.3 part of sodium bicarbonate, 0.1-0.3 part of choline chloride, 0.1-1 part of amino acid, 0.1-0.2 part of vitamin C, 0.5-1 part of a compound microecological preparation and 1 part of a compoumd premix. The granulated feed further contains at least two following components: 1-2 parts of potato residues, 1-2 parts of tomato pomace, 2-5 parts of rice bran meal and 1-3 parts of palm meal. The granulated feed is applied to the Xindan-series sows which farrow for three times or more, and the problems of constipation, dystocia, long parturient period and postpartum weakness of the Xindan-series sows in the gestation period as well as low birth weight and uniformity and the like of piglets are effectively relieved or solved.

Description

technical field [0001] The invention relates to the field of animal nutrition and feed processing, in particular to a broken feed for Xindan sows during pregnancy and a preparation method thereof. Background technique [0002] Breeding pigs bred in Denmark are famous for their high reproductive performance, high growth rate, high carcass quality, good meat quality, and high feed conversion rate. Compared with the Laodan breeding pigs, Xindan Landrace pigs have shorter ears, longer bodies, and stronger limbs and hooves than Laodan Landrace pigs; Xindan Large White pigs are larger than Laodan pigs The firmness of limbs and hooves and body length of white pigs have been greatly improved; the biggest change of Xindan Duroc lies in the further enhancement of firmness of limbs and hooves, scapula and hindquarters fullness. [0003] For the reproductive performance of Xindan primiparous sows, the total litter size of Large White pigs is 14.2 heads / litter, and the effective number ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a method containing live bacteria to solve many nutritional problems of multiparous sows during pregnancy, such as constipation, dystocia, long labor process, postpartum weakness, slow postpartum recovery, poor postpartum colostrum quality, low birth weight, and emaciation of newborn piglets. Preparation, vitamin C, active VD and dietary fiber feed for multiparous sows during pregnancy can regulate the balance of intestinal flora in sows, expand gastrointestinal volume, relieve constipation, relieve labor stress, improve postpartum appetite, and quickly regulate calcium in the body Phosphorus metabolism, preventing postpartum hypocalcemia, promoting the strength of limbs and hooves, improving the health level of sows, increasing the subsequent litter size and service life, and reducing the labor intensity of staff for nursing sows during pregnancy
