Abstract

The aim of this study was to evaluate the nutritive value and fermentation characteristic of king grass silage treated with addition of liquid or dried lactic acid bacteria (LAB) inoculant. Experiment was arranged to a completely randomized design with four treatments and three replications. Four treatments as follows (A) king grass without LAB inoculant as the control; (B) king grass + 30 ml of liquid of epiphytic LAB inoculant/kg of fresh forage; (C) king grass + 30 g of freeze-dried powder of LAB inoculant/kg of fresh forage; (D) king grass + 30 g of centrifuged powder of LAB inoculant/kg of fresh forage. The liquid LAB inoculant was sprayed on the top of grass and then mannualy mixed by hand. The intial LAB concentration in all inoculants were 1.0 × 106 cfu/g. About 500 g of silage materials were ensiled into plastic silos and stored at room temperatures (approximately 28oC) for 30 days. Results showed that pH value, concentrations of lactic acid, N-amonia (NH3-N), butyric acid and total volatile fatty acids (VFA) as well as Fleigh Point were affected by treatment of LAB inoculant. Silage treated with liquid or dried of LAB inoculant had lower (P

Abstract

This study was conducted in order to investigate the effects of a multivitamin complex and probiotic blend in drinking water before and after vaccination on growth performance, carcass traits, blood biochemical parameters and humoral immune response of broiler chickens. A total of 150 one day-old male broiler chicks (Ross 308) were randomly allocated to five treatment groups, with three replicates (10 birds per replicate) in a completely randomized design. Experimental treatments consisted of: 1) a basal diet and drinking water without any additives as control (C); 2) C + drinking water + multivitamin complex from 2 days before vaccination until 3 days after vaccination; 3) C + drinking water + multivitamin complex for 3 days after vaccination; 4) C + drinking water + probiotic blend from 2 days before vaccination until 3 days after vaccination; and 5) C + drinking water + probiotic blend for 3 days after vaccination. In the whole experimental period, feed intake, body and thigh weight and abdominal fat were significantly affected (P<0.05) by dietary treatments. On the contrary, no significant effect was observed on carcass characteristics, feed conversion ratio, blood parameters, antibody production against SRBC and IgG. The titer of IgM was higher in treatment (2) than other treatments at 28 d of age (P<0.05). In conclusion, a multivitamin complex supplied in drinking water for 2 days before vaccination till 3 days after vaccination is enable to improve broiler performance and immunity.

Abstract

The aim of this research was to determine the profit obtained from breeding of Timor deercommercially. This research was done in East Java. Survey method was used to answer the objective.The study location were selected by purposive sampling. Usually deer was develop in conservation area,but because the area was decrease so the number of deer also decrease. Model of deer raisingdevelopment should be improved not only for conservation but also for commercial purpose. Theoptimum deer raising were considered and monitored with a purpose to maximize commercial Timordeer by using Multiple Objective Goal Programming (MOGP) to find the Optimistic Rate Estimation.The result of this study showed to get the optimum benefit, it had to be applied together withconservation and commercial effort at the same time. Results of study showed that profit was taken fromselling velvet was 164.46%. Profits taken from selling antler was 350.56%, from selling alive deer was394.28%, from selling recreation tickets was 259.08%, from selling venison1 was 135.98%, and fromselling deer leather was 141.24%. Operational cost spent were 168.46% for feeding cost, 213.23% formaintenance cost, and 232.04% for labors’ salaries. The amount of operational cost required in MOGPmodel, with lower expenses and commercial priority were 185.54% for feeding cost, 253.13% formaintenance cost, and 246.95% for paying labors’ salaries. The MOGP model result with commercialpriority reached 335.21%, while in MOGP model with lower costs and commercial priority gave profitfor breeders up to 381.26%.

Abstract

Stearoyl-Coa desaturase (SCD1) gene is one of genes that involves in converting saturated fatty acids to unsaturated fatty acids. SNP at exon 5 in SCD1 gene that changes amino acid valine to alanine (V293A) has an influence to meat fatty acid composition. The aim of this research was to analyze SCD1 gene polymorphisms based on SNP V293A at exon 5 of three Indonesian local cattle. The identification of SCD1 gene polymorphisms was done by using 98, 20 and 7 DNA sample from Ciamis, Bali/Banteng, and Ongole Grade (PO) cattle, respectively. PCR_RFLP method with AciI enzim was carried out to identify SNP Val293Ala. Allelic frequencies and heterozygosity value were analyzed by using POPGENE32. The result showed that SCD1 gene at Ciamis local cattle and PO cattle were polymorphic. Their frequencies were 74.5% and 71.4% for T and 25.5% and 28.6% for C, respectively. There were three genotypes on Ciamis local cattle i.e TT, CT and CC with their frequencies were 52%, 44.9% and 3.10%, respectively. There were two genotypes on PO cattle i.e TT and CT with their frequencies were 42.9% and 57.1%, respectively. Meanwhile, SCD1 gene in Bali cattle was monomorphic. Heterozygosity value of SCD1 gene in Ciamis and PO cattle were 0.38 and 0.44, respectively. Their heterozigosities were categorized as medium.

Abstract

This experiment was conducted to estimate the actual milk yield and to compare the estimation accuracyof cumulative monthly record to actual milk yield by regression method. Materials used in this experimentwere records relating to milk yield and pedigree. The obtained data were categorized into 2 groups i.e. AgeGroup I (AG I) that was cow calving at < 36 months old as many as 33 cows with 33 lactation records andAG II that cows calving e” 36 months old as many as 44 cows with 105 lactation records. The first three toseven months data were used to estimate actual milk yield. Results showed that mean of milk yield/ head/lactation at AG I (2479.5 ± 461.5 kg) was lower than that of AG II (2989,7 ± 526,8 kg). Estimated milk yieldsfor three to seven months at AG I were 2455.6±419.7; 2455.7±432.9; 2455.5±446.4; 2455.6±450.8; 2455,64± 450,8; 2455,5 ± 459,3 kg respectively, meanwhile at AG II was 2972.3±479.8; 2972.0±497.2; 2972.4±509.6;2972.5±523.6 and 2972.5±535.1 respectively. Correlation coefficients between estimated and actual milkyield at AG I were 0.79; 0.82; 0.86; 0.86 and 0.88, respectively, meanwhile at AG II were 0.65; 0.66; 0.67;0.69 and 0.72 respectively. In conclusion, the mean of estimated milk yield at AG I was lower than AG II.The best record to estimate actual milk yield both at AG I and AG II were the seven cumulative months.
