将菹草颗粒添加在蛋鸭饲料中喂养,以考察它对红心蛋生产性能的影响.试验设置4个组,试验15 d(含适应期1 d),菹草颗粒添加量为0(对照组)、15%、20%和25%,并将其分别与100%、85%、80%和75%的普通蛋鸭配合饲料混合组成试验饲料.试验结果表明,在一定范围内,菹草颗粒的添加量与红心蛋的平均色度(指罗氏色度)及15度以上红心蛋所占的比例呈现一定的量效关系;其中将20%的菹草颗粒与80%的普通蛋鸭配合饲料混合组成的试验饲料综合效果最好.如正式喂养第4 d,蛋黄平均色度就由对照组的7度上升到15度,其差异达到极显著水平(P

Feeding trials were conducted to investigate the effects of supplementing pelleted potamogeton crispus L.feed (PPC) on the production properties of red-yolk duck eggs (yolk pigmentation, laying rate and mean egg weight). Four experiment groups were designed for a 15-days feeding trial of the laying ducks, of which the diet was supplemented with PPC at the levels of 0, 15%, 20% and 25% to be mixed with 100%, 85%, 80% and 75% common compound feed respectively. The results showed that there was a certain relationship between the PPC supplementation levels and the Roche color fan (RCF) score as we...
