Abstract

The use of corn waste and coffee pod as basal diet needs energy and protein supplementation in order to optimize rumen microbial growth. A research was done to study the appropriate supplement which is suitable based on the result of rumen fermentation kinetics. Four ruminally canulated cows, (205-224 kg of live weight) were placed in individual cages. The basal diet (BD) offered were corn waste and coffee pod mixture (80:20). Source of high degradable energy (HDE) was cassava pomace; while the low degradable energy (LDE) was arenga piñata waste. The high degradable protein (HDP) was mixed-concentrate while the low degradable protein (LDP) was leucaena leave meal. The supplementation of energy and protein to basal diet was in ratio of 50:50 based on dry matter. Feed offered were basal diet and the supplement at ratio of 60: 40 (3 % of LW). Observation was carried out for 4 periods (10 days/period). In each period, animal was fed one of the following diets:  A = BD, B = BD+ HDE+LDP, C = BD+LDE+LDP, and D = BD+HDE+HDP. Rumen kinetics observed were: pH, and VFA, NH3 and rumen microbial protein concentrations. Rumen fluid was taken at the end of each period gradually along the course of 24 hours fermentation. The results showed that the diets gave significant effect (P < 0.05) on rumen pH. The lowest rumen pH (5.76) was observed on diet D  at 2:00, 12 hours after feeding. Meanwhile, the highest pH (7.22) was found in animal fed diet A at 16:00. The total VFA on diet D of periode:1, 3 and 4 showed the highest level: 68.1 mmol/l; 75.37 mmol/l and 85.14 mmol/l respectively. The highest NH3 concentration was found in diet D followed  by diet C, B and A. At 12:00 observation or at 4 h after morning feeding the highest NH3 was observed from diet D (41.94 mg/100 ml). It is concluded that diet D resulted in the best rumen fermentation kinetic, therefore it could be used in feed formulation in cattle diets.

Abstract

The objective of study was to estimate breeding value of sires of Kebumen Ongole grade cattle based on offsprings weaning weight. This research was carried out from August to December 2015 in Urut Sewu area, Kebumen. The calculation of genetic parameter estimation was heritability of weaning weight. The value of heritability was used to calculate the breeding value of sires based on offsprings weaning weight. Heritability was calculated using paternal half-sib correlation with the direct pattern variance analysis. Breeding Value (BV) of sire was calculated by absolute estimated breeding value. The materials used in this study included were data record during the last three years (2013-2015) consisted of 41 sires, 51 dams and 244 calves. Weaning weight data had been corrected based on age of dams, sex and weaning age of 120 days. The results showed that the heritability value of weaning weight was included in high category (0.36 ± 0.21). The highest BV was KJ.J608 (49.76) with a ratio of 231.45%. The results of this study were expected to be the basis recommendation for selecting sires in Kebumen.

Abstract

The study was conducted to evaluate forage productivity of arbila (Phaseolus lunatus) as theruminant feed at various levels of rhizobium inoculants and harvesting times, was designed followingcompletely randomized design of factorial pattern with two factors. The first factor was the level ofinoculums (I) i.e. I1 (without inoculum), I2 (5 g/kg seed), I3 (10 g/kg seed), and I4 (15 g/kg seed). Thesecond factor was harvesting time (U) i.e. U1 (60 days), U2 (80 days), U3 (100 days) with 4replications. The variables were N uptake, production of dry matter (DM) and organic matter (OM), andpercentage of OM, crude protein (CP), crude fiber (CF), nitrogen free extract (NFE), extract ether (EE)and ash of arbila forage (based on DM). The results showed that inoculant treatment at the rate of 15g/kg seed produced the highest percentage of effective nodules (98.72%), and in combination withharvesting age at 100 days each polybag of plant was able to absorb the higest amount of N (688. 10 g)with production of DM 273.81 g, OM production 263.96 g and nutrients content based on DM of about91.14% OM, 33.52% CF, 34.76%, 5.75% EE, 09.37% ash, and 16.16% CP. From the study, it can beconcluded that arbila plants inoculated specific rhizobium Phaseolus vulgaris at the rate of 15 g/kg seedand harvested at 100 days yielded the best forage as feed.
