The invention discloses a natural
astaxanthin-containing premix compound which comprises the following components according to weight ratio: 30-80g / kg of broken wall
haematococcus pluvialis
powder, 150-300g / kg of bean pulp, 150-200g / kg of
calcium hydrophosphate, 150-250g / kg of mountain flour, 50-70g / kg of table salt, 0.6-0.9g / kg of nicotinic acid, 0.1-0.2g / kg of D-
calcium pantothenate, 0.0016-0.0024g / kg of
biotin, 7.5-12.5g / kg of
choline chloride, 0.256-0.512g / kg of
copper salt based on the content of
copper, 1-2g / kg of
ferric salt based on the content of ferrum, 1.2-2.4g / kg of
zinc salt based on the content of
zinc, 1.3-2.6g / kg of
manganese salt based on the content of
manganese, 0.02-0.04g / kg of
iodate salt based on the content of
iodate, 0.003-0.007g / kg of
selenium salt based on the content of
selenium, 20-35g / kg of
methionine, 0.33-1.0g / kg of ethoxy
quinoline, 1-3g / kg of
phytase, 5-15g / kg of composite microecologics, 1-3g / kg of xylo-
oligosaccharide and 80-120g / kg of
bentonite. The natural
astaxanthin-containing premix compound can remarkably improve the laying rate, reduce mortality and
elimination rate, ensure proper colors of red-
yolk eggs, promote the feed conversion rate, improve the production performance of laying hens and the
eggshell quality, reduce the occurrence of diseases, and improve the economic efficiency.
