subsequent productive performance and breast muscle development in fasted neonatal broiler chicks injected with calcium gluconate
نویسندگان
چکیده
this study was carried out to examine the effect of post hatch fasting (phf) period with and without subcutaneous injection of 0.6 ml ca-gluconate (ca-g) on productive performance and breast muscle development in broiler chicks up to day 28 of age. weight gain (wg) and feed intake (fi) were significantly reduced and fcr was increased as phf lasted for 36 h. injection of ca-g did not improve wg and fi of the chicks compared to the control group (without injection). post hath fasting through 36 h of age suppressed wg, fi and fcr and increased mortality rate up to day 28 of age (p>0.05). economic efficiency factor was decreased in coordinate with increase in phf periods and it was lower in ca-g injected birds compared to the control birds. breast weight, breast muscles weight, breast external dimensions and breast muscle histology was not affected by extended phf up to 48 h and ca-g injection. breast bone weight was decreased in the chicks experienced phf for 48 h. it was concluded that phf greater than 24 h has negative impact on productive performance in broiler chicks at 28 d of age. administration of ca-g to the neonate broiler chicks did not improve performance and showed an adverse effect on viability of the birds.
