Environmentally-friendly feed capable of improving yolk color of layer

Abstract

The invention discloses an environmentally-friendly feed capable of improving yolk color of a layer. The feed comprises the following components in parts by weight: 130 to 180 parts of calcium hydrogen phosphate from bones, 250 to 300 parts of stone powder, 50 to 70 parts of table salt, 12 to 20 parts of choline, 30 to 40 parts of composite trace elements, 10 to 15 parts of decavitamin, 20 to 30 parts of methionine, 350 to 500 parts of chrysanthemum meal, 2 parts of red chilli powder, 2 parts of leonurus, 2 parts of artemisia apiacea, 2 parts of phytase, and 2 parts of bacillus subtilis. The environmentally-friendly feed capable of improving yolk color of the layer is reasonable in collocation of nutrition; leonurus, artemisia apiacea and other Chinese herbal medicines enable deep yolk color, obvious raise of egg yield and improvement of disease resistance of the layer; calcium hydrogen phosphate from bones, serving as a phosphorus source, can reduce the utilization of non-renewable phosphate rock resources in the nature; and therefore, the feed is environmentally friendly and shows obvious economic benefit.

Description

technical field [0001] The invention relates to a feed, in particular to an environment-friendly feed for laying hens with improved egg yolk color. Background technique [0002] At present, laying hen feeds on the market mostly contain additives such as antibiotics, chemical synthetic drugs, and hormones. The chickens raised by these feeds generally have residues of toxic and harmful substances, and calcium hydrogen phosphate is usually used as a source of phosphorus for feed raw materials, but phosphate rock Belonging to non-renewable resources, to achieve sustainable development, it is urgent to find alternative raw materials. At the same time, the yolk color of eggs is a matter of concern to consumers. Pigments such as "jialisu yellow" are generally added to the feed of existing laying hens to achieve the purpose of improving the chroma. However, this pigment is an industrial product, whether it can be used safely There is currently no proof. Therefore, it is necessary ...
