During the two subsequent experiments involving isa vedette broiler chicks the effect of delay of first feeding and watering (0, 24, 48 and 72 hours) upon body weight and yolk sacc absorption as well as on glucose, protein, triglicerides and cholesterol levels in blood plasma were investigated. It was stated that chicks body weight during the first few days of life depended on the length of starvation period. With a starvation lasting over 24 hours the body weight was decreased (even below the initial body weight). Starved chicks used more residual yolk nutrients than those obtaining compound feed stuffs, especially if they were watered. With the chicks given feed 24-72 hours later than the controls the quotient: yolk sacc absorption/body weight was higher. The delay of the first feeding also resulted in lowered levels of plasma glucose and increased levels of protein, triglicerides and cholesterol. The impact depended on both the length of starvation and on the watering of chicks.
