Embodiment 1
[0025] The functional feed additive and functional complete feed that can be used to produce β-carotene enriched eggs are prepared by the following preferred method:
[0026] (1) Red pepper and Dunaliella salina dried to a water content of 4% are processed with a small-scale high-speed pulverizer, so that the particle size of the two plants reaches 60 mesh, and red pepper meal and Dunaliella salina meal are obtained.
[0027] (2) Mix 1kg of red pepper meal with 4kg of Dunaliella salina meal, and then add additive—0.6kg of feed grade Na 2 CO 3 Solid, mix well.
[0028] (3) Add the mixed red pepper / Dunaliella salina / auxiliary mixture into a vibrating grinder, grind for about 30 minutes, and finally make the particle size of the red pepper / Dunaliella salina micro-cut auxiliary powder reach about 400 mesh, and obtain Feed additive for the production of beta-carotene enriched eggs.
[0029] (4) Add the prepared feed additive to the poultry basal diet at a ratio of 0.5 to 3.5%, t...
Embodiment 2
[0031] Add 3.5% of the feed additive provided by the invention into the basal ration, mix well and evenly, and obtain the powder feed for laying hens rich in beta-carotene and various nutritional components in capsicum and dunali algae.
[0032] The test results showed that: compared with the control group, the average egg weight of the test group increased by 7.38%, the egg production rate increased by 8.79%, and the feed-to-egg ratio decreased by 6.53%. β-carotene in eggs increased by 209.03% on the 7th day of feeding, 524.6% on the 14th day of feeding, and was still 19.12% higher than that of the control group after 8 days of stopping feeding, with an average increase of 236.23%.
Embodiment 3
[0034] Add 1.0% of the feed additive provided by the invention into the basic ration, mix well and evenly, and obtain the powdery feed for laying hens rich in beta-carotene and various nutritional components in capsicum and dunali algae.
[0035] The test results showed that: compared with the control group, the average egg weight of the test group increased by 7.71%, the egg production rate increased by 4.81%, and the feed-to-egg ratio decreased by 7.87%. β-carotene in eggs increased by 159.35% after 7 days of feeding, 237.86% after 14 days of feeding, and 53.62% after 8 days of non-feeding, with an average increase of 159.72%.
