Nutritious forage for big pigs at latter fattening period

Abstract

The invention relates to nutritious forage for big pigs at latter fattening period. The nutritious forage comprises main materials and auxiliary materials, and the auxiliary materials comprise the following components: 1300 to 1600U of phytase, 1200 to 1300U of xylanase, 0.6 to 1.2% of cellulase and 25 to 34g of amylase to each kilogram of the main materials. The various enzymes are added into the main materials comprising corn flour, composite concentrated feed and wheat bran. The phytase mayhelp to improve digestion and absorption to nutrient substances of proteins, amino acids and trace elements etc; the xylanase may help to decrease the content of non-starch polysaccharides in the forage, and promote absorption and utilization of nutrient substances; the cellulase may be used for complete hydrolyzation of cellulose in the forage into glucose, so that helps to increase utilization rate of the forage; and the amylase may help to decompose macromolecule starch which is difficult to absorb into middle and low molecular substances which are easy to absorb, so that helps to increase utilization rate of the forage. According to the complementation of the components to each other, feeding time is decreased, utilization rate of the forage is increased, meat / feed ratio is increase and feeding cost is decreased.

Description

technical field [0001] The invention belongs to the technical field of fattening pig breeding, in particular to a nutritional feed for large pigs in the late fattening period. Background technique [0002] Pork tastes sweet and salty, and has the characteristics of thin bones, less tendons, and more meat. It is rich in protein, fat, carbohydrates, calcium, phosphorus, iron and other ingredients. It is the main non-staple food in daily life. It can strengthen the body and nourish yin. Dry, plump and moisturized skin. [0003] The breeding of pigs is divided into three stages: young pigs, medium pigs and large pigs. In each stage, different feed formulas are required to meet the physiological needs of pigs at this stage. The feed has strong digestion and absorption ability, and should be supplemented with balanced nutrition. The feed used is mainly corn flour, soybean meal, and wheat bran, and some auxiliary ingredients are added. With the development of technology, people ha...

Problems solved by technology

[0004] At present, the feed formula used by many farmers unilaterally increases the protein content, thinking that the feed quality with high protein is better, and the growth rate of pigs is faster, but after inspection, the protein content in pig feces is relatively high, and the smell of ammonia is strong. All indicate that the pigs did not fully absorb the protein, resulting in waste of feed

There are also some farmers who use lower-cost feed formulas, thinking that they can save farming costs, which is also unscientific. The utilization rate of feed is low, the time to slaughter is slow, and the disease resistance of pigs is significantly reduced.
