Growth and Carcass Physical Components of Thin Tail Rams Fed on Different Levels of Rice Bran

This experiment was aimed to investigate the effect of rice bran supplementation on live weight gain (LWG), the proportion of carcass meat, bone and fat of Thin Tail Rams. Twelve thin tail rams, aged about 12 months, weighed 20.95 ± 1.52 kg (CV = 7.26%) were allocated into a Randomized Block Design with 2 blocks and 3 treatments. The treatments applied were levels of rice bran supplementation, i.e. Napier grass ad libitum without rice bran (T1), Napier grass ad libitum and 200 g rice bran (T2) and Napier grass ad libitum and 400 g rice bran (T3). The results showed that rice bran supplementation highly significantly (P0.05) influence the percentage of carcass meat and bone percentage. It was concluded that rice bran supplementation increased slaughter weight, carcass weight and carcass percentage, carcass meat and bone weight, and carcass fat percentage, but did not influence the percentage of carcass meat and carcass bone.

Excretions of Urinary Creatinine on Young and Mature Kacang Goat Under Different Feeding Levels

. This study was aimed to examine the excretion of urinary creatinine in young and mature Kacang goat bucks under different feeding levels. This study used 16 Kacang goat bucks consisting of 2 groups of age, i.e. eight young bucks (aged 6-7 months, weighed 12.75±2.68 kg) and 8 mature bucks (age 9-12 months, weighed 17.34±3.32 kg). The bucks were fed pelleted complete feed containing 78.82% dry matter (DM), 18.80% crude protein (CP), and 76.29% total digestible nutrients (TDN). The bucks were allocated into a 2x2 nested design with four replications. The treatment was the amount of 2.24% dry matter intake (T1) and 4.48% of body weight (BW) (T2) for the young goat, while the mature buck was 1.87% and 3.74%, respectively. The results showed that DM, CP and TDN intake were significant different across ages and highly significantly different between feeding levels. Changes of urinary creatinine from week 0–12 showed no differences in the age group (142 mg/dl) and feeding level (143 mg/dl). Conclusively, age and feed level affected body weight, feed intake and creatinine excretion of Kacang Goat. The more body weight gain (age) and feed level, the more urinal creatinine excretion in male Kacang goat

Karakteristik Karkas Kambing Kacang, Kambing Peranakan Ettawa, dan Kambing Kejobong Jantan pada Umur Satu Tahun

Breed livestock was one of the factors that affected carcass characteristics before slaughter. The purpose of this study was to determine carcass characteristics includes the slaughter weight, , weight and percentage of carcass, carcass components (meat, bone, and fat) and meat bone ratio of three different breeds of goats in Central Java. The material used in this study were 11 male goats by age 1 year which consists of the Kacang goat (four heads), Ettawa Crossbred goat (four heads), and Kejobong goat (three heads). The research method used the Independent Sample Comparison. The data obtained were analyzed by analysis of variance, and if there was any significant difference it was followed by Duncan Multiple Range test. The results showed that the slaughter and carcass weight of Kacang goat (15 and 5.63 kg) was significantly (P <0.01) lower than Ettawa Crossbred goat (24.49 and 9.89 kg) and Kejobong goat (23.45 and 10.35 kg), but the carcass percentage were not significantly different (P> 0.05). Weight of meat, fat, bone, and connective tissue in Kacang goat (3.34 kg, 546.22 g, 1.56 kg and 146.98 g) was lower (P <0.01) than Ettawa Crossbred goat (6 .09 kg, 837.10 g, 2.65 kg and 301.30 g) and Kejobong goat (6.40 kg, 977.45 g, 2.67 kg and 293.64 g), but the percentage of carcass components were not significantly different. Meat bone ratio was not significantly different among the three breeds of goats, with an average of 2.61. It was concluded that the slaughter weight, carcass weight, and the weight of carcass components of male Kacang goat were lower than male Ettawa Crossbred goats, and male Kejobong at one year old, but the percentage of carcasses and carcass components relatively similar
