Problems solved by technology

[0005] The present invention aims to deal with the problems of high shortage of soybean meal and high price of protein feed, and the application of dephenolized cottonseed protein in dietary formula based on total amino acids cannot accurately meet the needs of animals for protein and amino acids. Soybean meal is used in the diet of medium and large pigs, adding appropriate synthetic amino acids to meet the nutritional needs of pigs for digestible amino acids, providing a corn-dephenolized cottonseed protein diet

Embodiment 1-3

[0020] Example 1-3 Effect of corn dephenolic cottonseed protein diet on the growth performance of 35kg-60kg growing pigs

[0021] Test material: Dephenolic cottonseed protein was provided by Hunan Fengkang Biotechnology Co., Ltd., and it met the national industry standard GH / T 1042-2007.

[0022] Test site: Experimental Base of Animal Nutrition Research Institute of Hunan Agricultural University

[0023] Experimental design: 72 Du-Growth pigs with similar body weights were randomly divided into 4 treatments with 6 replicates for each treatment. Examples 1, 2, and 3 replaced 50%, 75%, and 100% of the amount of protein such as soybean meal in the control group 1, respectively. Maintain consistent levels of crude protein, digestible energy and true digestible lysine. True digestible methionine, sulfur-containing amino acids, threonine and tryptophan meet the Chinese Pig Feeding Standard (2004) NY / T 65-2004. The test formula and nutritional level are shown in Table -1.

Abstract

The invention discloses corn-dephenolized cottonseed protein type feeds for medium pigs (each pig is 35-60kg)and large pigs (each pig is 60-100kg), which use corns as main energy raw materials, use dephenolized cottonseed protein as main protein raw materials and comprise corns, soybean meal, the dephenolized cottonseed protein, defatted rice bran, salt, mountain flour, calcium hydrophosphate, lysine hydrochloride and premix. A novel protein resource for feeds is developed, the feeds containing the dephenolized cottonseed protein for medium and large pigs can accurately meet the requirements of the pigs to the protein and amino acid and are equivalent to conventional corn-soybean meal type feeds in growth performance, slaughter performance, blood biochemical indexes and meat quality performance.

Description

Technical field [0001] The invention relates to a diet for animal feeding, in particular to a pig diet. Background technique [0002] Soybean meal is a high-quality protein feed resource with good protein quality and balanced amino acid. It is the main protein raw material for livestock and poultry feed. For a long time, the type of pig feed in my country is mainly corn-soybean meal, and there are few other types of feed. However, soybeans, the raw material for producing soybean meal, are over-reliant on imports, and prices vary greatly. Foreign capital controls more than 80% of soybean crushing capacity. According to the statistics of China National Grain and Oil Information Center, domestic soybean demand has been dependent on foreign countries as high as 78% in 2010. This situation is seriously dangerous to the safety of my country's edible oil and feed industries. How to choose alternative raw materials and save soybean meal consumption has always been a research hotspot in...
