Pig feed

Abstract

The invention relates to the field of feeds, and concretely relates to a pig feed. The pig feed is prepared from the following raw materials in parts by weight: 20 to 40 parts of corn flour, 15 to 25 parts of peanut meal, 20 to 30 parts of radix puerariae meal, 5 to15 parts of wheat bran, 10 to 18 parts of sweet potato residues, 5 to 15 parts of sesame powder, 4 to 10 parts of rock flour, 0.1 to 4.7 parts of diaminocaproic acid, 1 to 6 parts of table salt, 0.1 to 1.6 parts of decavitamin, 3 to 14 parts of pericarpium citri reticulatae, 0.001 to 0.016 part of probiotics, 0.6 to 4.7 parts of grease, and 0.7 to 2.5 parts of digestive enzyme. According to the pig feed provided by the invention, the probiotics, the grease and the digestive enzyme are added in a feed formula according to the growth characteristics of a pig, so that nutrient substances required for pig growth are comprehensively and balancedly provided, the intestine ecological balance in a pig body can be maintained, the absorption of trace elements is improved, the immunity is improved, and the morbidity and mortality rates are reduced.

Description

technical field [0001] The invention relates to the field of feed, in particular to a pig feed. Background technique [0002] Because pigs are easy to raise and have the characteristics of thin bones, less tendons and more meat, they have become the most common type of meat eaten by people. According to the statistics of the United States Department of Agriculture, in 2001 the total consumption of pork was the largest in China. In addition, China is also the place that produces the most pork, accounting for more than 46% of the world's pork meat. Pigs are raised with the existing feed. When the pig exceeds 90 kg, the daily weight gain slows down significantly, and the fat is mainly deposited, and the fat increases, which is not easy to sell. If it is less than 90 kg, it is slaughtered, although the feed utilization rate is high However, due to the small body weight and low meat yield, it is not economically cost-effective. Therefore, it is necessary to provide a feed for p...
