The Effect of Early Posthatch Local Feed in Pectoralis Muscle of Jawa Super Chicks (Gallus Gallus Domesticus)

摘要

This study was performed to study pectoralis muscle development in Jawa Super chicks in conjunction with local starter feed effect during the early post hatch period. Twenty Jawa Super day old chicks (DOC) were fed standard starter diet containing 20-21% crude protein during the experimental period. The chicks were divided into four groups consisted of five DOCs. The first group was starved for the first 3 days before continued with commercial diet until seventh days old. The second group was fed with standard chick starter commercial diet from post hatch until seventh days old, third group was fed with Formula 3 (F3) from posthatch until seventh days old and the forth group was fed with Formula 4 (F4) from posthatch until seventh days old. The parameters measured were body weight, pectoralis thoracicus weight, pectoralis thoracicus area, and cross-sectional area of the myofibers. Data gathered were statistically analyzed using one-way ANOVA, followed by Tukey Tests. The results showed that groups 1 and 4 had lower body weight, pectoralis thoracicus weight, pectoralis thoracicus area and cross-sectional myofiber area compared to group 2 and 3 (P≤0.05). The results of the current study suggested that early posthatch local feed F3 in Jawa Super chicks was important to body weight and pectoralis muscle development. The substitution of local feed F4 in early posthatch was not significant for pectoralis muscle development compared to standard chick starter commercial and F3 diet.
