Lactobacillus fermentum strains were successfully isolated from dangke which was a fresh cheese-like product originating from Enrekang, South Sulawesi Province, Indonesia. In addition, Lactobacillus plantarum and Lactobacillus acidophillus were isolated from beef. This study aimed to investigate the ability of those 8 LAB strains from dangke and beef in lowering cholesterol level by using in vitro study. Strain of Lactic acid bacteria used were L. fermentum strains (A323L, B111K, B323K, C113L, C212L), L. plantarum strains (IIA-1A5 and IIA-2C12), and L. acidophillus IIA-2B4. Variables observed were identification of Bile Salt Hydrolase (BSH) gene by Polymerase Chain Reaction (PCR), BSH activity and cholesterol assimilation. Phylogenetic tree indicated homology of L. plantarum IIA-IA5 was 98% to BSH gene of L. plantarum Lp529 with access code of FJ439771 and FJ439775 obtained from GenBank. The results demonstrated that eight strains of LAB isolated from dangke and beef that potentially showed cholesterol-lowering effects were L. fermentum B111K and L. plantarum IIA-1A5. L. fermentum B111K was able to assimilate cholesterol by 4.10% with assimilated cholesterol of 0.13 mg in 1010 cells. In addition, L. plantarum IIA-1A5 had BSH gene and BSH activity, as well as the ability to assimilate cholesterol by 8.10% with assimilated cholesterol of 0.06 mg in 1010 cells. It is concluded that L. fermentum B111K and L. plantarum IIA-1A5 were strains that showed cholesterol-lowering effects.

The main objective of Milk Producers Cooperative (MPC) is to provide services to the members and improve the performance of dairy farm of MPC members. The purposes of this study were: (1) to analyze dairy farm performance of MPC members, (2) to analyze performance of MPC services, and (3) to analyze the relationship between service performance of MPC with dairy farm performance of MPC members. The main data used were primary data. The analytical methods used included: descriptive analysis, profit analysis and R/C Ratio, and Chi-Square. The study showed that productivity and profitability of large-scale dairy farm was higher than small-scale. The performance of small-scale dairy farm of MPC members was relatively low both in terms of productivity and profitability. Most members judged that the performance of MPC services was good. There was a positive relationship between the MPC service performance (milk marketing, finance, technical assistance, and education/training) with the performance of dairy farm of MPC members. Coaching and more intensive services should continue to be given by the MPC to the members, especially the members with the small-scale dairy farms.

Biofat is a hexane extract containing several bioactive compounds with anacardic acid as the major compound. This study aimed to examine the effect of anacardic acid on rumen fermentation, especially methane and its degradation in the in vitro rumen fermentation. The study was arranged in a completely randomized block design. The treatments were control (substrate or complete feed), biofat (substrate + 0.75 uL/mL biofat), and anacardic acid (substrate + 0.75 uL/mL anacardic acid). Measured variables were total gas production, methane, pH, concentration of ammonia (NH3), dry matter degrability (DMD), organic matter degrability (OMD), and neutral detergent fiber degrability (NDFD) in the rumen. The chromatogram GC-MS analysis results indicated that the anacardic acid isolation process of the biofat produced nearly pure isolate (99.44%), and significantly decreased the production of methane by 51.21% and 39.62%, respectively. Anacardic acid degradation pattern in the in vitro rumen test showed a shifting of retention factor (Rf) value after anacardic acid being incubated with the degradation of anacardic acid occurred after 24 h of fermentation. In conclusion, anacardic acid isolated from biofat has a dominant role to reduce the in vitro methane production. Anacardic acid is very potential to be used as a methane reducing agent.

The aims of this research were to study the nutrient and secondary metabolite contents of solid herbal wastes (SHW) that were preserved by freeze drying, sun drying and silage, as well as to analyze their effects on in vitro fermentation indicators i.e., gas production kinetics and degradability of solid herbal waste. Physical and chemical properties on three forms of SHW (sun dry, freeze dry, and silage) were characterized and then an in vitro gas production experiment was performed to determine the kinetics of gas production, methane production, NH3, microbial protein, and SHW degradability. Polyethylene glycol (PEG) was added to the three treatments to determine the biological activity of tannins. Results showed that all three preparations of SHW still contained high nutrient and plant secondary metabolite contents. Gas production, methane, NH3, microbial protein, in vitro degradability of dry matter (IVDMD) and organic matter (IVDOM) of SHW silage were lower (P<0.05) compared to sun dry and freeze dry. These results were apparently due to the high content of secondary metabolites especially tannin. It can be concluded that solid herbal wastes (SHW) can be used as an alternative feed ingredients for ruminants with attention to the content of secondary metabolites that can affect the process of fermentation and digestibility in the rumen.

Potency of culled Saanen crossbred goat meat to replace the supply of yearling Boer crossbred goat meat was evaluated. Selected muscles from leg and shoulder cuts were analysed for their nutritional (proximate composition, collagen, amino acids, fatty acids), physicochemical (pH, myoglobin, drip loss, cook loss, shear force, lightness (L*) redness (a*) yellowness (b*), microstructure), and sensory (triangle test, hedonic test) evaluations. Meat samples from culled Saanen crossbred goat exhibited higher values in protein, collagen, and MUFA (P<0.05) than those from Boer crossbred goat, while lower values in ash, soluble collagen, and SFA were obtained (P<0.05). Meat from culled Saanen crossbred goat revealed higher cook loss, shear force, and redness compared to those from a yearling Boer crossbred goat (P<0.05). In addition, thicker perimysium in meat of Saanen crossbred goat was obtained particularly that could be seen on leg part. In sensory evaluation result, the panels could detect the differences between raw meat characteristics of these goat breeds (P<0.05) within the same muscle. However, the panels could not distinguish the difference between breeds in leg meat after being cooked. Shoulder meat of Saanen crossbred goat had less acceptance level compared to the other samples (P<0.05) particularly on its texture and taste quality. In summary, shoulder cut of culled Saanen crossbred goat exhibited a well-intentioned potency to substitute the supply of meat from yearling Boer crossbred goat. Nevertheless, pre-treatment might be applied to leg cut of Saanen crossbred goat to solve the less acceptance level of its textural and taste characteristics.

The objective of this research was to investigate the influences of generative stage on crude protein, crude fiber, ash, and crude fat contents as well as in-vitro dry matter and organic matter digestibilities of M-10 BMR sorghum mutant lines. This research was arranged into a randomized block design with 2 factors. The first factor was M-10 BMR sorghum mutant lines (Patir 3.1, Patir 3.2 and Patir 3.7) and the second factor was generative stages (flowering, soft dough and hard dough phase). The observed variables were proximate contents of stem, leaves and panicle of sorghum plant and in-vitro digestibility of whole plant. The results showed that leaves crude protein (CP) was more influenced by M-10 BMR sorghum mutant lines. Stems and panicles CP were influenced by the interaction between M-10 BMR sorghum mutant lines and generative stages. Further generative stage reduced stems CP but increased panicles CP. Crude fiber (CF), ash, and ether extract (EE) in leaves were not influenced by generative stages. Stems CF was influenced by M-10 BMR sorghum mutant lines and generative stages, while stems EE was more influenced by generative stages. Stems ash content was influenced by the interaction between M-10 BMR sorghum mutant lines and generative stages while panicles ash content was more influenced by generative stages. M-10 BMR sorghum mutant lines and hard dough phase increased in-vitro dry matter and organic matter digestibilities. Based on those findings, it can be concluded that the increased maturity reduces CP and CF contents so it increases in-vitro digestibilities.

Moringa oleifera (Moringa) leaves contain high levels of nutrition that can be utilized as a feed supplement to increase libido and semen quality. This study was aimed to evaluate the effect of Moringa leaves supplementation on libido and sperm quality of Bali bulls. This study used two-sample t-test on four Bali bulls were kept under individual pens for two periods of eight weeks. During the first period (control), the experimental Bali bulls were fed concentrates (1% of body weight) and rice straw ad libitum. During the second period, the experimental Bali bulls were fed similar to the first period with an additional of Moringa leaves 15% of the weight of the concentrate (treatments). Libido and sperm quality were measured twice a week. Plasma samples were taken three times a day (06:00, 14:00, and 22:00h) on the last day of each period. Plasma testosterone concentrations were analyzed by using ELISA techniques. Variables measured were compared using paired student's t-test. Supplementation of Moringa leaves increased testosterone levels (P<0.05) (4.57 vs 4.79, 0.45 vs 4.78, and 2.35 vs 5.63 ng/mL, respectively during 06.00; 14.00; and 22.00h), increased libido (P<0.05) (7.20±1.49 vs 3.49±0.40 min), and increased both the total motility (P<0.05) (63.99±3.37% vs 84.96±3.09%) and the progressive motility (P<0.05) (52.77±1.76% vs 67.03±3.74%) of sperm. Supplementation of Moringa leaves also increased (P<0.05) the velocity and the amplitude and decreased (P<0.05) the linearity of sperm. It can be concluded that the supplementation of Moringa leaves could increase plasma testosterone concentrations, libido, and sperm motility of Bali bulls.

Melanocortin 4 Receptor gene is involved in sympathetic nerve activity, adrenal and thyroid functions, and media for leptin in regulating energy balance and homeostasis. The aim of this research was to perform genetic analysis of MC4R gene sequences from Bligon goats. Fourty blood samples of Bligon does were used for DNA extraction. The primers were designed after alignment of 12 DNA sequences of MC4R gene from goat, sheep, and cattle. The primers were constructed on the Capra hircus MC4R gene sequence from GenBank (accession No. NM_001285591). Two DNA polymorphisms of MC4R were revealed in exon region (g.998 A/G and g.1079 C/T). The SNP g.998 A/G was a non-synonymous polymorphism i.e., changing of amino acid from methionine (Met) to isoleucine (Ile). The SNP g.1079 C/T was a synonymous polymorphism. Restriction enzyme mapping on Bligon goat MC4R gene revealed three restriction enzymes (RsaI (GT’AC), Acc651 (G’GTAC_C), and KpnI (G_GTAC’C), which can recognize the SNP at g.1079 C/T. The restriction enzymes may be used for genotyping of the gene target using PCR-RFLP method in the future research.

The objective of this study was to determine energy and protein requirements, for both maintenance and gain, of sheep in Indonesia by using a meta-analysis method. A database was developed from various in vivo experiments involving sheep as the experimental animals in which energy intake, protein intake and average daily weight gain (ADG) were reported. A total of 38 articles consisting of 137 data points were integrated into the database. Different breeds (Priangan, fat-tailed and local) and sexes (male and female) were specified in the database. Maintenance and gain requirements of dry matter, energy and protein were determined by regressing ADG with dry matter intake (DMI), total digestible nutrient intake (TDNI) and crude protein intake (CPI), respectively. An intercept (where ADG= 0 g/kg MBW/d) and a slope (required nutrient intake per unit ADG) were taken as maintenance and gain requirements, respectively. Results revealed that all sheep breeds had similar energy requirement for maintenance (TDNm). Energy requirement for gain (TDNg) of Priangan breed was lower than other breeds; the breed required 0.860 g TDN for 1 g ADG. Fat-tailed and local breeds required 1.22 and 2.75 g TDN for 1 g ADG, respectively. All breeds also revealed relatively similar protein requirement for maintenance (CPm), i.e. 6.27-6.47 g/kg MBW/d. Priangan breed required less CP for 1 g ADG (CPg), i.e. 0.295 g. Requirements of CPg for fat-tailed and local breeds were 0.336 and 0.497 g/g ADG, respectively. It was concluded that each sheep breed in Indonesia had specific TDN and CP requirements for gain, but similar requirements for maintenance.

The chicken growth hormone (GH) and its receptor (growth hormone receptor, GHR) play important roles in chicken performances due to their crucial functions in growth. The variations of GH and GHR genes were then thought to be associated with the variations of the performances. This experiment was designed to identify the g.2248G>A GH and the g.565G>A GHR loci polymorphisms and to evaluate their associations with carcass components in Kampung and broiler chicken cross. A total of 215 chickens including 4 chicken populations (Kampung, Cobb broiler, F1, and F2 Kampung x broiler chicken cross) were screened to identify polymorphism using PCR-RFLP technique with EcoRV and Eco72I restriction enzyme for GH and GHR loci, respectively. The carcass components were recorded at 26 weeks of age on F2 Kampung and broiler chicken cross (42 chickens) for association study. Both the g.2248G>A GH and the g.565G>A GHR loci were polymorphic with two alleles (G and A) and three genotypes (GG, AG, and AA). The GG genotype and the G allele of GH locus were predominant in all chicken populations. While in GHR locus, the AA genotype and the A allele were found to be higher in all chicken populations. The association study showed that the g.565G>A GHR locus polymorphism had significant effect on carcass components, including live weight, carcass weight, breast weight, thighs weight, breast muscle weight, and thighs muscle weight. There was no significant association was found between the g.2248G>A GH genotype and carcass components. It could be concluded that the g.2248G>A GH and the g.565G>A GHR loci were polymorphic in Kampung and broiler chicken cross and the g.565G>A GHR locus was accosiated with carcass components. This g.565G>A GHR SNP might be an important candidate marker for chicken growth and muscle mass improvement.
