Kappa casein (ĸ-cn) gene as one of the four casein genes commonly has two variant alleles. B allele is positively correlated with milk proteins, so potentially be used as MAS to improve milk protein content. This study aimed to identify genetic variation of the ĸ-casein gene in Holstein-Friesian (HF) from several dairy regions in West Java. Blood samples were taken through jugular vein of lactating heifers and cows, from intensive managements under the Local Government Dairy Breeding Station - Cikole (BBPT Cikole-SP) (82 hds), Embryo Transfer Station (BET) (50 hds), and Eco Farm of Animal Science Faculty of Bogor Agricultural University (EcoFarm) (20 hds); as well as from semi-intensive managements of small dairy farmers under the supervision of the North Lembang Cooperative Unit (KPSBU Lembang) in two villages of Cilumber (98 hds) and Pasar Kemis (92 hds). Blood samples were also taken via cocsigalis vein of AI (active and non active) HF bulls at the two National AI Stations in Lembang (25 hds) and Singosari (32 hds). Identification of genetic variation was by applying PCR-RFLP method. Three genotypes were identified, namely AA, AB, and BB, resulting two alleles of A and B. Results entirely showed that the frequencies of the BB HF female were very low, with the range of 0%-6% (vs AA genotype= 10%-54% and AB genotype= 46%-85%), despite of the relatively high frequency of the B allele over the A allele (23%-48% vs. 52%-77%). The low frequency of the observed BB females might be due to the limited AI active BB bulls used for services by the two national AI stations (0%-4%).

Duck meat is not preferred because its off-odor. Its off-odor is caused by lipid oxidation which preventable by antioxidant. Beluntas has antioxidant and anti nutrition. This research was designed to know the level of beluntas and feeding duration on performance, chemical, and duck's meat off-odor. Beluntas was given to 108 culling ducks, about 12 months old. The research used a completely randomized design with 3 x 3 factorial models, with 3 replicates. The factors were different levels of beluntas (0%, 1%, and 2%) in the ration, and feeding duration of each ration (3, 5, and 7 weeks). The data collected were analyzed using analysis of variance and Tukey's test. The results showed that no interaction was found between the two factors. Beluntas did not affect duck's performance. Feeding duration of each ration affected the fat and fatty acid content (P < 0.01) and TBARS (thiobarbituric reactive subtances) value of the meat with skin (P < 0.05). Beluntas level at 1% increased C18:0 (P < 0.05) and total (C18:2 and C18:3) (P < 0.052). Beluntas levels at 1% and 2% reduced (P < 0.01) duck's meat off-odor and increased (P < 0.05) consumers preference. This research concluded that the inclusion of 1% beluntas for 3 weeks was effective to reduce duck's meat off-odor without negative impact on performance.

A field trial was conducted to study the effect of dietary inclusion of palm oil solid waste on milk production of murrah buffalo raised under palm oil plantation. Two farms from different districts were involved in this study. Forty cows with 7-9 month pregnancy were selected from each farm and they were divided into control and treatment groups. Cows in control group were offered a mixed supplement of 1 kg copra meal + 2 kg fresh grated cassava root + mineral mix and treatments group were offered the control diet + 1 kg palm oil solid waste. The dietary supplement was offered to the cows for 2 months before and 2 months period after calving. The cows were grazed under palm oil plantation. The addition of palm oil solid waste in the diet improved (P < 0.05) milk yield (8.5 l/d vs 10.5 l /d), calves weight at birth (19.6 kg vs 22.1 kg) and live weight gain of the calves (0.66 kg/d vs 0.99 kg/d). Additional dietary inclusion of palm oil solid waste improved milk yield of murrah buffalo, and further improvement of milk yield was expected to achieve by higher inclusion of palm oil solid waste in the diet.

Growth hormone receptor (GHR) is one factor affecting animal growth. GHR is required by growth hormone (GH) to carry out its effects on target tissues. The objective of the study was to estimate genetic diversity of the GHR|AluI gene in bali, limousin, simmental and pesisir cattle. Genotyping was performed on 248 animals, including 162 bali, 21 limousin, 17 simmental and 48 pesisir. Single nucleotide polymorphisms (SNP) had been found in exon 10, coding for the cytoplasmic domain of GHR, which was located at position 81 bp (A/G) induced amino acid substitutions Ser/Gly. Genotype frequencies of bali cattle AA (0.988), GG (0.006) and AG (0.006) were evidenced for the GHR AluI monomorphism, but mostly different from limousin GG (0.667), AA (0.238) and AG (0.095), simmental AG (0.529), GG (0.471) and AA (0.000), pesisir AA (0.604), GG (0.375) and AG (0.021) were the evidence of polymorphism. Homozigosity (monomorphism) in bali cattle might be affected by adaptability in extreme environmental conditions such as poor nutrition and improper management practices. It also could be affected by natural selection and phenotype plasticity phenomena.

Anoa is Indonesia endemic fauna that included into Appendix I by CITES. Anoa breeding efforts have not succeed, due to their agressivity, soliter, wildness and monogamous. The aim of this experiment was to observe morphology and biometry of anoa's sperm stained using William's (W) and eosin-nigrosin (EN). Semen was collected from two male anoas by electroejaculator. Slides was made for morphology and biometry observation of ejaculate. The results showed that abnormal sperm morphology of the mature anoa (10 years) was 32.27%-35.00%, meanwhile the young one (3 years) was 24.03%-31.89%. In mature anoa, measurement for head width, and midpiece and tail length of sperm were not signficantly different between W and EN staining, but significantly different (P < 0.05) for head and total length. In the young anoa, sperm biometry for head width was not significanly different between W and EN staining. In both W and EN staining, biometry for head width and total length were not significantly different between mature and young anoas, but significantly different for head, midpiece and tail length. According to sperm morphology, semen from the young anoa was slightly better than those of the mature anoa. Staining method and age could affect to biometry of the anoa's sperm.

Lesser mouse deer is a native animal, which is commonly found in the forest of Java and information concerning this animal is still limited. This research explored the quality of lesser mouse deer meat (Tragulus javanicus). Eight lesser mouse deer (four females and four males) were used in quality aspects of lesser mouse deer meat. The physical properties observed were pH, water holding capacity, tenderness, and cooking loss. While the chemical properties observed were proximate analysis, amino acids, fatty acids, cholesterol, and EPA-DHA of the meat. The results showed that meat samples had average of ultimate pH (6.32), water holding capacity (32.82%), tenderness (1.80 kg f/m2), and cooking loss (45.15%). The average meat chemical compositions namely content of water, protein, fat, ash and cholesterol were 76.33%, 21.42%, 0.51%, 1.20%, and 50.00 mg/100 g, respectively. Fatty acids consisted of lauric, miristic, palmitic, stearic, oleic, linoleic, and linolenic acid were in the amount of 1.04% 3.09%, 30.97%, 0.77%, 59.41%, 3.22%, and 1.12%, respectively. The total EPA and DHA was 0.13% and 0.05%. Respectively, the results showed that quality aspects of lesser mouse deer meat had a high ultimate pH, low water holding capacity, tenderness, high cooking loss, and high water content, high protein, low fat and high cholesterol.

Acacia mangium bark is abundant byproduct of wood industry in Indonesia. It is underutilized and mainly used as fire wood for the wood industry. The bark contains high level of tannin but the tannin has not been extracted or produced commercially. Tannin isolate can be used for several purposes such as tanning agent for leather, adhesive for plywood or particle board, etc. In ruminant, tannin can be detrimental but can also be beneficial. This experiment was aimed of getting the highest yield of tannin extract with the highest biological activity in rumen fermentation. Nine different solvents at different temperatures were used to extract tannin from A. mangium bark. The extracts were analyzed for their tannin contents and biological activities. Tannin content was analyzed using folin ciocalteau and butanol-HCl methods. Biological activity was described as a percentage of an increase in gas production in the in vitro rumen-buffer fermentation, with and without addition of PEG. The results show that Na2SO3 solution extracted more tannin than other solutions and the higher the concentration of Na2SO3 solution, the higher the yield of tannin extract. The solution of 6% sodium sulphite gave the highest yield of tannin extract (31.2% of original bark sample) and the highest concentration of tannin (18.26%) but produced a negative effect on in vitro fermentation (% increase of gas production = 2.70%). Extraction with 50% acetone gave a high yield of extract (22.28% of original bark) which contained 12.98% of tannin and showed the highest biological response (% increase of gas production = 216%). In conclusion, sodium sulphite solution is not recommended for tannin extraction if the tannin will be used as feed additive in ruminant feed; on the other hand, the aqueous acetone (50% acetone) solution is a better choice to be used.

The present experiment was aimed to identify the phytochemical of Jatropha curcas leave extracted with water and methanol as an anthelmintic agent for Ascaridia galli, and its effect on native chicken performance. In vitro study of anthelmintic activity was conducted by counting the number of paralyzed worm dead-body of A. galli during 18 hours in petri dish containing different levels of extract, namely 0%, 1%, 2%, 3%, and 4% (w/v) and compared to the piperazine 0.5% (w/v). Eightteen birds of naturally A. galli-infected native chicken were used for the in vivo study. The treatments were 0%, 2%, 4%, 8%, and 16% of J. curcass leave extract, and 10% of piperazine using a completely randomized block design with 6 treatments and 3 replications. Parameters observed were fecal worm egg count, feed consumption, body weight gain, feed conversion ratio, and mortality. The results showed that water- and methanol-extracted J. curcas leave had similar composition of secondary metabolite compounds which is high in triterpenoid and steroid contents, respectively. Percentage of paralyzed A. galli was higher (P < 0.01) in water-extracted jatropha leaves. On the contrary, the dead-body percentage was higher (P < 0.05) in the methanol-extracted than that in the control group. In vivo study showed that leave meal significantly decreased (P < 0.05) fecal worm egg count. The leaf meal at the level 16% tended to increase feed consumption, body weight gain, and significantly decreased feed conversion ratio. In conclusion, J. curcas leave meal have anthelmintic activity to A. galli and could improve nutrient utilization of naturally A. galli-infected native chicken by decreasing feed conversion ratio.

A mineral formula composed of three locally available materials: limestone originated from Bukit Kamang of West Sumatra, freshwater oyster shell and bone meal and fortified with micro minerals of Cu, Zn and I was investigated as mineral supplement for diet of laying hens. The experimental diets were: P0 (diet contained of 6% commercial mineral), P1 (diet contained of 6% local mineral), P2 (diet contained of 6% Bukit Kamangs' limestone) and P3 (diet contained of 6% fresh water oyster shell meal). The total of four experimental diets was then fed to 120 laying hens. The hens were divided into 3 groups based on body weight: heavy, medium and light. Each group was subdivided into 4 subgroups in accordance with number of treatments, so that each treatment consisted of 3 replicates containing of 10 hens. Parameters measured included: feed intake, hen-day egg production, feed conversion ratio (FCR), eggshell quality, mineral retention and mineral composition of tibia bone. Data were subjected to statistical analysis using variance analysis in a completely block design with 4 treatments and 3 blocks as replicates The results showed that the egg weight and eggshell qualities were found not significantly difference, but different mineral sources gave significant effect on egg production and bone mineralization. The laying performances and tibia bone weight of chickens fed diet mixed with the local mineral formula were found not significantly different with those fed diet mixed with commercial formula, but significantly better (P < 0.05) than those of fed diet mixed with only limestone or oyster shell. Hens fed with diet mixed with Bukit Kamangs' limestone showed better performances and heavier tibia bone than those fed with diet mixed with oyster shell. It was concluded that the local mineral formula could be used as sole mineral source for laying hens. The nutritive value of Bukit Kamangs' limestone was better than that of fresh water oyster shell.

A study to evaluate the implementation of integrated poultry production through contract farming system in Lombok, NTB was carried out from June to November 2009. The descriptive methods were used whilst the data was collected using survey methods. Fifty contract farmers were selected to measure the business performance with references on management, performance production index, FCR, and percentage of mortality. The results of this study indicated that the contract broiler production was chosen due to: (1) risk sharing (27.6%), financial credits (25.8%), and the guarantee of marketing (23.3 %). Dissatisfaction particularly in aspects of incentive determination, the quota, and margins. The margin ratios between farmers and integrators, 30%: 70%; 40%: 60% or 50%: 50% with no clear reasons. Performance parameter was as an expectation, suggesting feed quality and management aspects were well implemented. In respect to Syariah bank, its outstanding was well understood but it have not been attractive to the contract farmers. The capital is not the main reason to work with the integrators. The government involvement was needed to encourage poultry industry growth and looking for the new potential region and legislation on maintaining environment. New investors should be encouraged to overcome instability price.
