Effects of sex and age upon utilization of zinc in chickens

Popis výsledku v původním jazyce

Effects of sex and age of chickens upon zinc utilization was investigated in an experiment with 128 chickens divided into 16 groups. 8 groups of chickens received in a practical type of feed mixture and drinking water 96 mg of Zn per 1 kg of consumed drymatter and 8 groups received only 83 mg of Zn. During the growing period from Day 12 to Day 56, the experiment was divided into 15 balance periods. Utilization of zinc from both diets decreased highly significantly (P<0.01) with the increasing age. In chickens fed on a diet higher in Zn, the content of this element per 1 g of live body gain decreased with age and was in average 38.6 2.59 ug. In case of a lower Zn diet, its content per unit of body gain increased up to Day 36 and, thereafter, a gradualdecrease could be observed; the average content was 32.2 1.38 ug. The growth rate of the total amount of Zn in the organism was slightly lower than that of body weight. The effect of sex on values under study was not significant.
