Corn-free pig feed

Abstract

The invention discloses a corn-free pig feed which is prepared from the following raw materials in percentage by weight: 68-64% of wheat middling, 2-3% of pichia pastoris, 3-2% of animal hide glue, 2.9-3.8% of cottonseed meal, 5-6% of corn germ meal, 14-16% of bran, 4% of premix, 0.1-0.2% of choline chloride and 1% of a microorganism additive. Water is added into the raw materials, and the raw materials are stacked and fermented for 5-7 days and are fed to pigs directly. According to the corn-free pig feed, wheat middling takes the place of corn completely, the use amount of bean pulp is reduced, the wheat middling is increased, and cheap raw materials of pichia pastoris and animal hide glue with low values are abandoned, so that the resource is saved, the feed cost is lowered, the mycotoxin is reduced, and the productivity of pigs is increased.

Description

technical field

[0001] The invention belongs to the technical field of feed, in particular to a corn-free pig feed. Background technique

[0002] The development of the breeding industry has intensified the "competition between humans and animals for food". Corn and soybean meal are commonly used feed ingredients in the breeding industry, and are the main ingredients in pig and poultry feed formulas. The proportion of corn in pig feed formula generally exceeds 60%, and the sum of corn and soybean meal generally exceeds 80%. Corn-soybean meal-based rations are currently the main typical pig rations in my country. In recent years, the price of corn has risen by more than 20%, resulting in an increase in feed costs and restricting the development of the aquaculture industry. At the same time, corn is prone to mildew, and mycotoxin poisoning incidents occur from time to time. my country's soybean meal relies heavily on foreign markets. In order to meet the demand for cotton m...

example 1

[0020] A total of 64 Dudachang three-way hybrid pigs with a body weight of 60.0±0.5kg were selected in Pingyin pig farm, and were randomly divided into control group and test group, with 4 replicates in each group and 8 pigs in each replicate. The control group was fed corn diet, and the test group was fed corn diet. The diet formula and raw material prices are shown in Table 1. The corn diet of the control group was the basic diet prepared according to the national pig nutrition standard in 2004, and its specific indicators were: digestible energy 13.4MJ / kg, crude protein 14.8%, and lysine 0.72%. The pre-feeding period is 7 days and the official period is 42 days. During the whole experiment, the pigs were raised on the cement floor, and the manure was dried and cleaned manually. Feed intake, daily gain, and feed-to-meat ratio were counted during the experiment. The test data were analyzed by T test using SAS software (version 8.1). The test results are shown in Table 2. ...

[0025] In the Liaocheng pig farm, 80 Du long-term three-way hybrid pigs with a weight of 55.5±0.5kg were selected and randomly divided into a control group and an experimental group, with 5 replicates in each group and 8 pigs in each replicate. The control group was fed corn diet, and the test group was fed corn diet. Table 3 shows the diet formula and raw material prices. The corn diet of the control group was the basic diet prepared according to the national pig nutrition standard in 2004, and its specific indicators were: digestible energy 13.4MJ / kg, crude protein 15.5%, and lysine 0.81%. The pre-feeding period is 7 days and the official period is 50 days. During the whole experiment, the pigs were raised on the cement floor, and the manure was dried and cleaned manually. Feed intake, daily gain, and feed-to-meat ratio were counted during the experiment. The test data were analyzed by T-test using SAS software. The test results are shown in Table 4.

[0030] Forty pigs with a body weight of 63.0±0.5kg were selected from Yanggu county pig farm and randomly divided into control group and test group, with 4 replicates in each group and 5 pigs in each replicate. The control group was fed corn ration, and the test group was fed corn ration. See Table 5 for the ration formula and raw material prices. The corn diet of the control group was the basic diet prepared according to the national pig nutrition standard in 2004, and its specific indicators were: digestible energy 13.4MJ / kg, crude protein 14.5%, and lysine 0.70%.
