Abstract

Poultry production performance is reflected by body weight gain, ration conversion and carcass percentage. This study was conducted with the aim of knowing the optimum level of use of fermented pineapple peel in the ration on production performance and carcass percentage of male Peking ducks. The research material was male Peking duck aged 3 weeks with initial body weight of 343.90 ± 0.90 g. 240 male Peking ducks were placed randomly in battery cages based on a Completely Randomized Design with 6 treatments and 5 replications, namely P0=ration without fermented pineapple peel (FPP); P1=the ration contains 5% FPP; P2=ration contains 10% FPP; P3=the ration contains 15% FPP; P4= ration contains 20% FPP and P5=the ration contains 25% FPP.  Based on One way ANOVA analysis and Duncan's test, it was found that the use of fermented pineapple peel 10% significantly (P<0.05) increased the final body weight (1.693g/head), body weight gain (1.350 g/head), and carcass percentage (55.25%). From the results of the study, it can be concluded that the optimum level of use of fermented pineapple peel with yeast culture on body weight gain, slaughter weight, carcass weight and carcass percentage, respectively: 8.80%; 8.40%; 7.25% and 9.50%.

Abstract

The objective of this research was to investigate the body measurements of female Arabian chickens during the laying phase. The study utilized a sample of 95 female Arabian chickens, aged 94 weeks, which were housed in battery cages and utilized for egg production. Direct measurements were taken on each chicken, with variables including body weight, head circumference, beak length, comb height, neck length, back length, wing length, chest width, chest depth, upper thigh length, lower thigh length, shank length, shank circumference, the distance between the pubis bones, the distance between the pubic bone and sternum, and the length of the phalanges. The results of the study indicated that the body weight and morphometric measurements of the Arabian chickens were consistent with prior research. Furthermore, the size of the chest, back, neck, and wings displayed a significant correlation with body weight. Therefore, these measurements can be used as indicative markers for predicting the body weight of Arabian chickens.
