Premix compound containing trace elements

Abstract

The invention provides a premix compound containing trace elements. The premix compound is formed by selecting the trace elements such as Cu, Fe, Zn and Mg and mixing the trace elements according to a required amount, and is mainly used as a pig feed additive. The premix compound not only can play a role in biochemical balance, but also has a specific effect of stimulating growth. When feeding condition and technology are ensured, for raising a pig, 20 percent of feed can be saved, the weight increment can be increased by 25 percent, the lean meat rate can be increased by 10 percent, and the profit of about 40 yuan can be increased.

Description

technical field [0001] The invention provides a premix composed of trace elements. Select trace elements Cu, Fe, Zn, Mg, mix according to the required amount, mainly as feed premix for pigs. technical background [0002] According to the 78th annual meeting of the American Society of Animal Husbandry, the research results of Bauman Boyed and others were introduced. The data obtained show that the growth hormone PGH secreted by the pituitary gland can improve the growth performance and carcass composition of pigs. Dr. T. D. Etherton of Pennsylvania State University has conducted research on PGH for four years. The research has proved that when pigs are raised to 260 pounds, the feed conversion ratio of pigs using PGH is 2.3 compared with conventional pigs. ~2.4, the weight gain rate increased by 17-18%, and the muscle weight increased by 13-16%. Facts have proved that PGH has greatly improved the three factors of great economic significance for pigs: weight gain, feed conv...

Problems solved by technology

However, most of the research done on PGH so far is to use the method of injecting the hormone every day. Many people think that this is obviously not practical. What is needed is to invent a practical feeding method.

[0003] The application and production of additive premixes in my country are relatively backward, such as lysine and methionine, which lack large-scale production capacity; vitamins are also in short supply and expensive; trace elements (including mineral elements) only play a role in biochemical balance and have The content of harmful metals is relatively high, and some quality standards have not yet been determined; the varieties of antibiotic growth promoters are restricted and restricted
