Problems solved by technology

After slaughter, the unsaturated fatty acids in pork are prone to oxidative rancidity, which affects the sensory and hygienic indicators of meat and shortens the shelf life of pork, which brings difficulties to pork sellers and meat product processors

Embodiment Construction

[0017] 1.1 Test diet

[0018] The basal diet for the test was formulated with reference to the nutritional requirements of finishing pigs in the US NRC (1998), the pig feeding standards promulgated by the Ministry of Agriculture of China in 2004, and the "Chinese Feed Composition and Nutritional Value Table (20th Edition, 2009)". And the main nutritional levels are shown in Table 1.

Abstract

The invention discloses a fattening pig feed without bean pulp and calcium hydrophosphate, which is prepared through the following components in percentage by weight: 67.4% of corn, 30.00% of corn DDDGS, 1.22% of mountain flour, 0.30% of salt, 0.33% of lysine with effective content of more than 98%, 0.02% of tryptophan with effective content of more than 98%, 0.07% of threonine with effective content of more than 98%, 0.1% of choline chloride with effective content of more than 50%, 0.2% of trace element premix, 0.02% of vitamin premix, 0.04% of vitamin E and 0.3% of sodium selenite. Side effects of low growing speed of pigs, quality reduction of pork and short storage period caused by highly-added corn DDDGS are eliminated and the content of unsaturated fatty acid in intramuscular fat, back fat, abdominal fat and liver fat can be increased, the oxidation resistance of muscular tissues can be improved and the storage time of pork can be prolonged to 3-5 days.

Description

technical field [0001] The invention belongs to the application field of agriculture and animal husbandry, and in particular relates to a feed for fattening pigs that does not contain soybean meal and calcium hydrogen phosphate. Background technique [0002] In recent years, my country's animal husbandry and feed industry have developed very rapidly, and the contradiction of shortage of feed resources has become increasingly prominent. According to expert forecasts, from 2010 to 2020, the balance of protein feed in my country will be 24-48 million tons, and the balance of cakes will be 25.6 million tons. For a long time, soybean meal has been mainly used as protein feed raw material in my country, which has caused the supply of soybean meal to become increasingly tight and the price to rise and fluctuate irregularly. With the acceleration of domestic pig breeding scale and the widespread promotion of corn-soybean meal formula, the proportion of soybean meal in feed cost is ...
