Herbivorous pig feed

Abstract

The invention provides herbivorous pig feed, and relates to livestock feed. The feed comprises the following components in percentage by mass: 50% of maize straw, 20% of oil bran and 30% of soybean straw, and comprises the following nutritive components in percentage by mass: 8.40% of crude protein, 6.28% of crude fat, 9.66% of crude fibers, 0.311% of calcium and 0.24% of phosphor. The growing period technical process and the harvesting elaborate processing are implemented for the maize straw and the soybean straw to prepare the high-nutrition livestock feed which can be absorbed by the livestock, so that the feed cost is largely reduced, and the development of animal husbandry is advanced; the feed has excellent ecological and economical benefits through the straw returning to the fields. As the maize straw is used as the main feed, the nutrition needs of the pig growth can be satisfied, the meat factor is increased, the pig intestinal digestion is modified so as to digest and absorb the nutritive substances, the feces odor is relieved to a certain degree, the immunocompetence can be improved, the meat quality is comprehensively improved, and the fresh and tender pure-natural green foods are produced.

Description

technical field [0001] The invention relates to a feed for domestic animals, in particular to a feed for Bama pigs and black pigs containing wild boar gene. Background technique [0002] As an inevitable product of agricultural production, crop straw is a very precious resource. According to statistics, the annual output of crop straw in my country is about 600 million tons. At present, about 30% of the country's straw is directly used as fuel for rural life; 10% is used for livestock feed; 23% is used for sideline production; and 6% is returned directly to the field. However, a large amount of straw was burned on the spot, which not only led to a rapid increase in the content of PM10, PM2.5 elemental carbon, organic carbon, and total carbon in the air, but also promoted the formation of haze weather, seriously polluted the environment, and led to an increase in inhalable particulate matter , endangering human health. Simultaneously, the burning of straw can easily ignite...

Problems solved by technology

However, a large amount of straw was burned on the spot, which not only led to a rapid increase in the content of PM10, PM2.5 elemental carbon, organic carbon, and total carbon in the air, but also promoted the formation of haze weather, seriously polluted the environment, and led to an increase in inhalable particulate matter , endanger human health

At the same time, the burning of straw can easily ignite the surrounding combustibles and cause a fire.

A large amount of smog formed by straw burning greatly reduces visibility and affects road traffic and aviation safety

Straw burning reduces the return of straw to the field, and also destroys the soil structure, resulting in a decline in the quality of cultivated land
