The aim of this study was to identify the variation of 5’UTR CAPN1 gene and its association to growth traits in Bali cattle. DNA samples were obtained from 80 heads of Bali cattle originated from BPTU-HPT Denpasar. The average of Bali cattle age was 784 days (631 days-1098 days). Bali cattle were divided into 3 age groups namely, the first group (1.5 years to 2 years), the second group (2 years to 2.5 years), and the third group (2.5 years to 3 years). The observed growth traits were birth weight (kg), live weights (kg), average daily gain (kg), body length (cm), chest depth (cm), withers height (cm), hip height (cm), and heart girth (cm). Polymorphism identification of 5’UTR CAPN1 gene was conducted by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) with BglII as the restriction enzyme. Growth traits data association were analyzed using the General Linear Model (GLM) analysis. The 5’UTR CAPN1 gene|BglII was polymorphic in Bali cattle (GG, GT, and TT). Genotype frequencies for Bali cattle were 0.30 (GG), 0.66 (GT), and 0.04 (TT). The allele frequencies of G and T allele were 0.63 and 0.37, respectively. The G allele was the most frequent allele and GT genotype was the most frequent genotype among the cattle. The CAPN1|BglII had a significant effect (p<0.05) on growth traits in Bali cattle. Animal carrier of GG genotype had higher live weight and average daily gain than those with GT genotype, while the lowest values were associated with TT genotype.

Our research was designed to identify the sequence variations of heat shock protein 70 (HSP70) gene in three breeds of native Indonesian chickens, Kampung Unggul Balitbangtan (KUB) chicken, Walik chicken, and Kate Walik chicken. Total DNA was isolated from the whole blood using a DNeasy blood and tissue kit. The HSP70 gene was amplified and sequenced from 94 chickens using PCR. The amplification product was 787 bp long, consisting of a 210 bp promoter region, a 112 bp long 5′untranslated region (UTR), and a 465 bp protein coding region. Our KUB, Walik, and Kate Walik chicken HSP70 gene sequence alignments express genetic diversity in the promoter region (insertions and deletions), 5′UTR (deletions and nucleotide substitutions), and at the beginning of the coding region (nucleotide substitutions). Four haplotypes, H1, H2, H3, and H4, were identified in the HSP70 gene protein coding region. The haplotype H2 was found in all three chickens, while H4 was only found in Walik chicken. The H4 is a novel haplotype which never reported before. Based on a median-joining network analysis, H4 is a haplotype produced by mutations at two specific sites (g.370A>G and g.388C>G) in the protein coding region of the HSP70 gene of the chicken. It could be concluded that Walik chicken can be used as a standard for heat stress genotyping in Indonesian local chickens, because it has complete HSP70 gene haplotypes.

This study aimed to assay L. plantarum (P1), S. cerevisiae (P2), and its combination (P3) as probiotics candidates and their effects on nutrient digestibility in Japanese quails (Cortunix cortunix japonica) diets. In vitro assays were employed to evaluate the antibacterial activities against pathogenic bacteria (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella pullorum), sensitivity to antibiotics (i.e., streptomycin, penicillin, and erythromycin), stress on bile salt and acidity condition. Evaluation of probiotics on in vivo nutrient utilization was carried out by administration of probiotics to laying quails in drinking water with various treatments (R0, control; R1, L. plantarum; R2, S. cerevisiae; R3, combination of R1+R2; R4, commercial feed additive). Results showed that the highest inhibitory activity was performed by P2 on S. aureus (17.28 mm). Treatments P2 and P3 were resistant to all the tested antibiotics, while P1 was resistant to streptomycin and penicillin. P1 was tolerant to bile salts whereas P2 was tolerant to gastric acidity conditions. For the in vivo experiment, quails fed R1, R2, and R4 had higher nitrogen retention as compared to R0 (p<0.05). However, all treatments revealed similar metabolizable energy values. The cluster analysis showed that quails consuming the combination of L. plantarum and S. cerevisiae were within the same cluster with the control but different clusters from the individual probiotics across all parameters, indicating a possible antagonistic effect between the two species. In conclusion, the inclusion of L. plantarum or S. cerevisiae inhibits pathogenic bacteria without influencing nutrient utilization of quail diet.

One-hundred male broiler chickens (Cobb500) were assigned randomly in a completely randomized design (CRD) into four dietary treatment groups to determine the effects of various components (whole kernel, kernel oil, kernel defatted) of candlenut (Aleurites moluccana) kernel on growth performance, carcass yield, and proximate and fatty acid composition in meat during the grower-finisher stage. Each treatment consisted of 5 replicates with 5 birds for each replications. From 21 to 42 days of age, the birds were offered either one of the following dietary treatments namely; Basal diet containing no candlenut kernel (T1), Basal diet containing 2.5% whole candlenut kernel (T2), Basal diet containing 2.5% candlenut kernel oil (T3), and Basal diet containing 2.5% candlenut kernel defatted (T4). The significant difference was determined when the probability level was p<0.05. Birds fed the experimental diets showed no significant difference on growth performance, carcass yield, and proximate and fatty acid compositions in meat. However, birds fed diets containing various components of candlenut had small effect on reducing feed intake, decreasing crude protein and crude fat contents in meat, and increasing total C18:2n-6 and n-6 PUFA. In conclusion, supplementation of various components of candlenut kernel in broiler diet did not improve growth performance, carcass yield, and proximate and fatty acid compositions in meat.

The study aimed to determine the best of nitrogen fertilizer level based on growth and biomass production of brown midrib sorghum mutant line Patir 3.7. This research was conducted at the Field Laboratory in the Faculty of Animal Science, Andalas University, Padang. The experiment was assigned in a completely randomized block design with 4 levels of nitrogen fertilizer application and 3 replications. The treatments consisted of N0= 0 kg N ha-1 as a control; N1= 50 kg N ha-1; N2= 100 kg N ha-1; and N3= 150 kg N ha-1. Agronomic and production variables measured were plant height, stem diameter, leaf width length, leaf stem panicle ratio, stem Brix sugar content, as well as fresh biomass and nutrient production. Analysis of variance followed by Duncan Multiple Range Test (DMRT) was conducted. The results showed that the addition of nitrogen fertilizer produced the highest stem diameter, leaf length, leaf width, leaf ratio, and stem ratio (p<0.05). However, the panicle ratio and stem Brix sugar contents were not significantly affected (p>0.05) by the level of nitrogen fertilizer. The fresh biomass, dry matter, crude protein, ash, NFE, and TDN production increased significantly (p<0.05) with the increased level of nitrogen fertilizer. Based on those findings, it can be concluded that nitrogen fertilizer application at the level of 50 kg N ha-1 produces better growth, fresh biomass, dry matter, and nutrients production.

The objective of this study is to evaluate the characteristics of smallholder beef cattle production in Central Vietnam. A total of 360 households were interviewed by using semi-structured questionnaire; a total of 606 beef cows were investigated for evaluating calving interval (CI). Thirty-two fattening cattle were monitored for the estimation of diet structure. Results showed that the cattle herd size was 4.32-4.45 cattle/household. In North Central (NC), 55% of surveyed farmers kept local cattle, 45% kept crossbreeds, and none of surveyed farmers keeping exotic breeds. In South Central (SC), 63% of surveyed farmers kept cross cattle, 32% kept local cattle, and 5% kept exotic breeds. In the breeding method, 70% of surveyed farmers used artificial insemination (AI), 20% used natural mating (NM), and only 10% used both AI and NM in SC, whereas in NC 40% of farmers used AI, 40% used NM, and 20% used both AI and NM. The variety of feedstuffs fed to cattle including roughages and concentrate. The concentrate in the diet for fattening cattle was 25%-35% and protein level was 11%-13%, and the average daily gain of cattle was 0.51-0.63 kg/day. The CI of cows was 12-13 months in SC, whereas in NC it was 13-14 months. There were numerous constraints to cattle production in surveyed households including diseases, lack of good quality feed sources, breeds, knowledge, and lack of capital. In conclusion, cattle production in Central Vietnam is small scale and still largely extensive. There are constraints that must be solved to improve livestock systems in the near future, especially when shifting towards semi-intensive and/or intensive cattle production systems.

The larvae of black soldier fly/BSF (Hermetia illucens) seems to be a considerable material as an alternative to antibiotic growth promoters (AGPs) since they are rich in antimicrobial peptides (AMPs) and lauric acid that can improve the health and immune response. This study aimed to evaluate the effect of BSF larvae meal as a replacement of fish meal on production performances, health status, and immune response of quails. The experimental design using completely randomized design consisted of 3 treatments of dose of BSF larvae meal i.e., R0: ration without supplementation of BSF larvae meal; R1: ration supplemented with 6.57% BSF larvae meal to substitute 50% fish meal, and R2: ration supplemented with 13.15% BSF larvae meal to substitute 100% fish meal. The parameters observed were production performances, hematological profile, macrophage phagocytic activity and capacity, and antibody titer against the avian influenza virus. A completely randomized design was arranged with 3 treatments and 5 replications and data collected were analyzed by using one-way analysis of variance (ANOVA). The results showed that ration supplemented with 13.15% BSF larvae meal demonstrated significant effects on the enhancement of egg production and egg mass (p<0.05). Based on hematological profile, the health status of experimental quails was unaltered by the treatments, but immune response of quails fed ration supplemented with 13.15% BSF larvae meal was found to be significantly increased as revealed by the increased average macrophage phagocytic activity and capacity, as well as a higher antibody titer against avian influenza virus (p<0.05). It is concluded that black soldier fly (BSF) larvae meal can be used as an alternative substitution to fish meal up to 13.15%, based on the improvement of immune response and the increase in egg production of quails.

Feed plays an important role in determining the success of livestock businesses and also as a significant cost factor. Feed contributes 60%-80% of the total production costs. The types of feed could have different effects on the cost, efficiency, and productivity of livestock business. Some laying-hen farmers in Blitar District use two kinds of feed, semi self-mixed feed, and total self-mixed feed. This study was conducted to compare the use of two types of feed on the net revenue of laying hen farmers in Blitar Regency. The research used the survey method. The sample in this research consisted of 100 laying-hen farmers in Blitar Regency, 50 of them used semi self-mixing feed and the rest used total self-mixing feed. Data were collected from several laying hen farms in Blitar Regency with a survey method. All data were then analyzed both qualitatively and quantitatively. The average feed price of semi self-mixed feed and total self-mixed feeds were IDR 5,143.38 and IDR 4,854.91 per kg, respectively. The results showed that the feed price, cost of medication/vaccine, the amount of feed, and egg production for semi self-mixed feed farmers had significant effects on the net revenue of the farmer (p<0.05), with the average net revenue being IDR 12,785,471.68 per 1,000 birds/period. Whereas for total self-mixed feed, the medication/vaccine cost and feed amount had significant effects on the net revenue of the farmer (p<0.05), with the average net revenue being IDR 18,467,373.76 per 1,000 birds/period. As a conclusion, the total self-mixed feed showed more optimal net revenue of laying hen than semi self-mixed feed.

The objective of this study was to evaluate the effect of noni (Morinda citrifolia) leaf shoot meal (NLSM) supplementation in the ration on the performances of kampong chickens as well as lipid, malondialdehyde (MDA), and fatty acid contents of meats. Two hundred and forty kampong chickens of 4 weeks old were reared until 12 weeks old. The diet treatments were R0: 0% NLSM (control), R1: 0.5% NLSM, R2: 1% NLSM, R3: 1.5% NLSM, R4: 2% NLSM, and R5: 2.5% NLSM. A completely randomized design (CRD) was used with six treatments and four replications with ten kampong chickens per replicate. The data were analyzed using ANOVA and if there were significant different, the data were further analyzed using Duncan’s Multiple Range Test. The variables measured were performances of kampong chickens as well as lipid, MDA, and fatty acid contents of meat. The result showed that cholesterol and LDL contents of meat were significantly reduced by feeding NLSM. Performance and HDL contents of meat were not significantly different for all diet treatments. In addition, feeding kampong chickens with ration supplemented with NLSM could reduce MDA, saturated fatty acids and increase unsaturated fatty acids contents of meat. It is concluded that 2.5% NLSM can be used to improve meat quality of kampong chicken as functional meat.
