Concentrated feed for over-sized fattening pigs and preparation method thereof

Abstract

The invention relates to concentrated feed for over-sized fattening pigs and a preparation method thereof, belonging to the technical field of pig feed. The feed is prepared from the following raw materials in parts by weight: bean pulp, corn DDGS (distillers dried grains with soluble), soybean oil, mountain flour, calcium hydrogen phosphate, salt, organic selenium, 50% vitamin E, choline, 35% vitamin C, 75% glycine betaine, 98.5% lysine, threonine, an antioxidant, a mildew preventive, a composite enzyme preparation, a feed microecological preparation, phytase, a sweetening agent, a vitamin premix, a trace element premix and middlings bran. The later-stage physiological development characteristics of the over-sized fattening pigs are combined, the composite enzyme preparation and the microecological preparation are used for regulating the intestinal health of the pigs, no antibiotics are utilized, the normal feeding mode is changed, and after the concentrated feed is used for feeding the over-sized fattening pigs with weight of 125kg for 90-100 days before marketing, drug residues in meat are remarkably reduced, and the meat is relatively safe and excellent.

Description

technical field [0001] The invention relates to a pig feed and a preparation method thereof. More specifically, the invention relates to a super-large fattening pig concentrated feed and a preparation method thereof, belonging to the technical field of pig feed. Background technique [0002] In some areas in northern my country, such as Inner Mongolia, Changchun, Harbin, etc., because the local people like to eat fat pork, they are used to raising fat pigs to a weight of about 200 kg for slaughter. (100-120 kg body weight) is 0.8-2 yuan / kg higher, and the economic benefits of breeding are relatively stable. In these areas, the breeding mode of raising extra-large fat pigs has gradually formed. However, my country's national pig nutrition standards and the US NRC2012 have not formulated corresponding nutritional requirements for the extra-large fattening stage (125 to 200 kg body weight stage). [0003] Since the northern region is rich in grain crops such as corn and wh...

Problems solved by technology

[0006] The concentrated pig feed mentioned in the first article is mainly for feeding piglets, and contains a large amount of expanded soybeans, whey powder and fish meal. Feeding this kind of diet to extra-large fattening pigs will reduce the carcass lean meat percentage on the one hand, and lead to Feeding costs are too high

[0007] The second item above is a miscellaneous meal-type fermented concentrate made of puffed sweet potato dry powder, peeled puffed full-fat soybean, puffed peanut meal, broad bean flour protein, puffed cottonseed meal, puffed blood powder, etc. Feed raw materials are not easy to obtain, which is not conducive to large-scale promotion and use
