Abstract

The present invention relates to the field of animal nutrition, and particularly relates to a trace element premix feed and weaned piglet compound feed. The trace element premix feed does not contain copper sulfate, but contains copper citrate. The compound feed can decrease the amount of copper used in the feed by more than 88%, improve average daily gain (ADG), average daily feed intake (ADFI) and feed to gain ratio (F / G) of piglets compared with high dose copper sulfate, increase lysozyme concentration of serum by more than 50.62%, reduce diarrhea rate of piglets by more than 66.67%, and decrease fecal copper content by more than 88.76%; the above data has highly significant differences (P<0.01) compared with the control group.

Description

technical field [0001] The invention relates to the field of animal nutrition, in particular to a microelement premix feed and compound feed for weaned piglets. Background technique [0002] Copper is an essential trace element for animals and plays an important role in promoting animal growth and improving body immunity. In 1945, Brude found for the first time that adding high doses of copper sulfate could significantly improve pig performance. Since then, high copper has been widely used in animal feed. At present, the amount of copper added in the compound feed for weaned piglets has reached as high as 150-200 mg / kg, which is more than 10 times the normal requirement. [0003] The use of copper sulfate in high doses has great potential safety hazards to the animals themselves, the ecological environment and livestock and poultry products. If high copper is used in the feed, it is necessary to add high iron and high zinc to match it, which will easily lead to excessive ...
