Apparent digestibility of fat and nitrogen retention in young chicks

Popis výsledku v původním jazyce

Apparent fat digestibility and nitrogen retention were examined in broilers and laying type cockerels within the first 15 days of life. Differences between birds with and without deutectomy were studied as well. In chicks without deutectomy, there was arapid decrease in fat digestibility from Day 2 to Day 6 and from Day 3 to Day 7 in broiler and egg type hybrids, respectively. This drop was followed by an increase till Day 14. Observed changes may be connected with excretion of endogenous nutrients originating primarily from the yolk sac. In deutectomized chicks, fat digestibility increased within the period of Days 2 to 14. The utilisation of nitrogen in broilers was highly significantly (P<0.001) higher than in egg type chicks. The dependence of coefficients of apparent nitrogen retention on age of chicks could be expressed by means of parabola equations with the maximum values on Days 12 - 13. The amount of N retained in the organism per unit of weight gain increased with the incre
