The aimed of this experiment to study the supplementation of urea molasses block for performance increased of ettawah crossbred goats fed diet containing Gliricidia spium green forage has been conducted at Tabanan regency and Animal Nutrition Laboratory. The Latin Square Design which four treatments and four replicates was used in this experiment. The four treatments were the levels of urea molasses block : 0, 50, 100 and 150g respectively. The animal access to ad libitum Gliricidia spium green forage and drink water. The animal fed twice a day urea molasses block at the morning and at the afternoon. The variables which were observed including feed consumption, nutrient digestibility, body weight gain and feed conversion ratio. The result of this experiment showed dry matter feed consumption, drink water, nutrient digestibility of the four treatments is not significantly different (P >0.05). The body weight gain at treatment C was significantly higher (P <0.05), but feed conversion ratio (FCR) was significantly lower (P <0.05) than treatments A, B and D. From the results in this experiment it can be concluded that the used of urea molasses block 100g on the effect to increased the performance of ettawah crossbred goats with basal diet Gliricidia spium green forage.
ABSTRAKPenelitian ini bertujuan untuk mengetahui keseimbangan energi dan protein sapi Bali jantan yang diberi ransum dengan level protein dan energi. Rancangan yang digunakan : rancangan acak kelompok (RAK) dengan lima perlakuan dan tiga kelompok bobot badan. Bobot sapi berkisar 198,00 kg. Kelima perlakuan ransum yaitu: (A) 15,42% protein dan GE 4,02 Mkal/kg DM; (B) 14,74% protein dan GE 3,75 Mkal/kg DM; (C) 13,11% protein dan GE 3,79 Mkal/kg DM; (D) 10,33% protein dan GE 3,92 Mkal/kg DM dan (E) 10,58% protein dan GE 3,53 Mkal/kg DM. Peubah yang diukur : konsumsi energi, konsumsi protein, energi tercerna, protein tercerna, energi termetabolis, retensi energi dan retensi protein. Hasil penelitian menunjukkan konsumsi energi, energi tercerna dan energi termetabolis tidak menunjukkan perbedaan yang nyata (P>0,05), sedangkan konsumsi protein, protein tercerna, retensi energi dan retensi protein pada perlakuan A nyata lebih tinggi (P<0,05) dibandingkan dengan perlakuan E. Hasil penelitian ini dapat disimpulkan konsumsi energi, konsumsi protein, energi tercerna, protein tercerna, retensi energi dan retensi protein tertinggi pada imbangan 15,42% protein dan GE 4,02 Mkal/kg DM.Kata kunci: keseimbangan protein dan energi, sapi bali jantan ABSTRACTThe research was conducted to determine protein to energy ratio of Bali bull rations (body weight ranged from 198.67 to 207.00 kg) fed at certain levels. The experiment used a randomized block design (RCBD) with five treatments and three weight group replications. The treatments consisted of various P-E ratios, namely; (A) protein 15. 42% and GE 4.02 Mcal / kg DM; (B) protein 14.74% and GE 3.75 Mcal / kg DM; (C) protein 13.11% and GE 3.79 Mcal / kg DM; (D) protein 10.33% and GE 3.92 Mcal / kg DM and (E) 10.58% and GE 3.53 Mcal / kg DM. The variables measured were the consumption of energy and protein, digestible energy, digestible protein, metabolizable energy, energy and protein retention. The results showed that the energy consumption, digestible energy and metabolizable energy did not show significant differences (P> 0.05), whereas protein consumption, digestible protein, energy and protein retention for treatment A was significantly higher (P<0,05) than treatment E. In conclusion, treatment A (15,42% protein and GE 4,02 Mcal/kg DM )resulted in the highest level of the energy and protein consumption, digestible energy, digestible protein, and retention of energy and protein.Keywords: protein to energy ratio, bali cattle.

The aim of this study was to find out the influence of vitamin-mineral supplementation on digestibility and rumen fermentation in Bali cattle. The randomized block design with 4 treatments and 4 replications were used in the research. In this study was used 16 Bali cattle with body weight around 295.31+23.07 kg. Rations used in the treatments were Treatment A (control): rice straw ad libitum plus commercial feed; Treatment B: Treatment A ration plus 0.2% vitamin-mineral in commercial feed; Treatment C: Treatment A ration plus 0.3% vitamin-mineral in commercial feed, and Treatment D: Treatment A ration plus 0.4% vitamin-mineral in commercial feed. Parameters measured were nutrient digestibility, rumen metabolites and urinary allantoin. The results showed that supplementation of vitamin-mineral at 0.2 -0.4% in commercial feed did not increase the digestibility of dry matter, organic matter, crude protein and crude fiber, except for dry matter and organic matter digestibilities at 0.2% supplementation (p<0.05). However, the vitamin-mineral supplementation increased concentrations of partial VFA and ammonia as well as for methane gas production, except for VFA and ammonia at 0.4% level. Vitamin-mineral supplementation at 0.2-0.4% level did not affected pH value of rumen fluid and urinary allantoin.
