Abstract

Pasak Bumi (Eurycoma longifolia Jack/ELJ) is frequently claimmed to increase expression of masculinity, including inducing the lean growth. This study was aimed to determine the effect of ELJ peptide supplementation on yield and physical composition of lamb carcasses. Sixteen Priangan rams about 1 year old with average weight of 30.43±1.41 kg were maintained in individual cages. The experimental rams were divided into 4 treatments i.e. T0, T1, T2, and T3. In T0, T1 and T2 treatments, the experimental rams were administered: 0, 1.5, and 3 mg ELJ peptide/kg BW, respectively. In the T3 treatment, the experimental ram were administered 1 mg/kg commercial product eurypeptide®. The ELJ peptide and commercial product were administered first in the morning prior to feeding. The experiment was conducted in a completely randomized design of four treatments and four replications. Data were covariance analyzed with an empty body weight as covariate for carcass weight and the right carcass weight as covariate for carcasses physical composition. The results showed that the weights of dissection body fat of T2 and T3 were lower than T0 (P < 0.05) and T1 (P < 0.01). Fat weight reduction was found in all parts of the carcass and more apparent in the fore saddle. Lean weights were higher ( P < 0.05) in T3 and T2 as compared to T1 and T0. The pattern of lean weight differed among treatments in the wholesale cuts that follow the total lean weight eventhough it was not significant. ELJ peptide treatment did not significantly affect either bone weight or wholesale cuts weight. In conclusion, T2 and T3 can improve carcass composition with equal ability.

Abstract

Productivity data from 560 head of PO cattle have been collected for 9 years from 2004 until 2013 for evaluating heritability estimation and environmental factors affecting production traits of Indonesian Ongole cross from birth to yearling old. Heritability estimation were analyzed using varians analysis with data of paternal halfsib correlation. Varians component for to estimate of heritability value were analyzed using completely randomized design one - way classification. While a general linear model was used to analyze the environmental factors (sex, year, parity, season and type of births). The results showed that sex of calves and year of births had significant differences (P<0.05) for all production traits such as weight at birth, weaning and yearling, while the type of birth only presented a significant difference on birth weight. Parity, season and generation exhibited nonsignificantly effect on those production traits. Estimation of heritability on birth weight, weaning weight and yearling weight were 0.28+0.12; 0.47+0.15 and 0.63+0.17 respectively. The highest heritability values obtained in yearling weight, this means that yearling weight will be effective as selection criteria to improve the genetic of PO cattle.
