چکیده
effects of post-hatch fasting (phf) and subcutaneous injection of ca-gluconate (ca-g) on productive performance, immune response and mortality of broiler chicks were investigated using 640 one-day-old ross 308 chicks in a 5×2 factorial experiment with five phf levels (zero, 12, 24, 36 and 48 h) and two ca-g injection levels (zero and 0.7 ml) in a completely randomized block design in four replicate pens of 16 birds each up to day 28 of age. the extended pfd up to 36 h significantly decreased body weight and percentage of monocytes and increased mortality of the chicks. injection of ca-g increased mortality of the birds by six-fold compared with the control birds (p

Four hundred and eighty mixed-sex broiler chicks aged 3 hrs after hatching were allotted according to a completely random design in a 6 × 2 × 2 factorial schedule into 2 groups of 12 replications of 20 chicks each. The main experimental factors were fasting for 0, 6, 12, 24, 36, and 48 hrs after chick placement, calcium gluconate (Ca-glu) injection (0 and 0.6 mL) and sex (male and female). Inde...
متن کاملSpread of hatch and delayed feed access affect post hatch performance of female broiler chicks up to day 5.
It is not rare that newly hatched chicks remain without feed for about 24 to 48 h before they are placed on farms due to a series of logistic operations. Furthermore, the spread in hatching time can also mount up to 30 to 48 h for late v. early hatchers. In other words, the practice is a complex combination of spread of hatch and delayed feed access. The present study was aimed to investigate t...
