Abstract

An experiment was carried out to study the effect of early chick nutritional supplements (ECNS) with 600-day old straight run broiler chicks from a single hatch. The chicks were allocated to five treatments randomly each with four replicates of 30 chicks. The chicks were wing banded, individually weighed. Group 1 formed the control group (T1- without ECNS) and the chicks in the group 2 to 5 were fed with one of the following ECNS viz., Egg white protein-glucose based ECNS (T2), Corn-soybean and fish meal based ECNS without steaming (T3), Steamed corn-soyabean and fish meal based ECNS (T4), Commercial broiler pre-starter diet as ECNS (T5) immediately after hatch in the hatcher tray and continued till placing the chicks in the chick transport box. Chicks in the control group were subjected to fasting for 24 hours to simulate field conditions. The data on liver and pectoral muscle glycogen, jejunal and ileal histomorphometry of birds and the economics of feeding different ECNS were analyzed. The results of the study revealed that the ECNS feeding significantly (P<0.01) improved liver and muscle glycogen in day old chicks than those of fasted control. The gut morphology viz. villi height, width, crypt depth and villi surface area were significantly (P<0.01) improved in jejunum and ileum of early fed broiler chicks compared to fasted chicks. The net profit was increased in early post-hatch ECNS feeding groups. It could be concluded that ECNS feeding significantly improved the liver and muscle glycogen reserves and jejunal and ileal histo-morphometry which assures gut development in broilers.
