Low-protein daily ration for lactating sows

Abstract

The invention relates to a low-protein daily ration for lactating sows. The feed is prepared from the following components in parts by weight: 29-34 parts of corn, 7-8.5 parts of broken rice, 20-25 parts of wheat, 2-5 parts of alfalfa, 5-8 parts of rice bran, 10-14 parts of soybean meal, 3-4 parts of broad beans, 1-3 parts of silkworm chrysalis, 5-8 parts of earthworm powder, 0.3-0.7 part of sesame oil, 0.2-0.5 part of soybean lecithin, 0.1-0.3 part of calcium hydrophosphate, 1.1-1.8 parts of mountain flour, 2 parts of a premix, 0.01-0.04 part of a compound enzyme preparation and 0.04-0.08 part of a microecological preparation. The daily ration formula can reduce the production cost, and when the daily ration is used for feeding lactating sows, on one hand, the feed intake of the sows can be promoted, the utilization rate of nutrient substances by the sows is increased, the intestinal function is improved, constipation is reduced, and postpartum recovery of the sows is accelerated; on the other hand, the utilization rate of nutrient substances in daily ration can be increased, so that emission of nitrogen and phosphorus in sow excrement is reduced, and green breeding is achieved.

Description

technical field

[0001] The invention belongs to the field of feed, in particular to a diet for low-protein lactating sows. Background technique

[0002] At present, pork consumption of Chinese residents accounts for 62% of meat consumption. Pig feed accounts for 43% of my country's compound feed, and is an important factor in feed grain and food security. However, the precise formulation of pig feed in my country is faced with many types of feed raw materials, and the nutritional value of the same feed raw material varies greatly due to the variation of species, origin, processing technology and other factors. In terms of pigs, there are a variety of pig breeds in my country, and the breeding level, environmental facilities and nutritional requirements of pigs are also different.

[0003] The so-called low-protein diet refers to a diet with a lower protein level than a high-protein diet. The high-protein diet here is usually a typical diet or a diet formulated according to...
