Abstract

Beef cattle farmers were interviewed about what “sustainability” means to them with regard to their daily practices, both in their daily working life and after being confronted with the results of an assessment conducted on their farms prior to a focus group discussion (FGD) utilizing the Sustainability Assessment of Food and Agriculture (SAFA) system developed by the Food and Agriculture Organization (FAO) of the United Nations. The study presented in this article was based on two FGDs, using the results of the SAFA online assessment as a tool to initiate and facilitate the discussions. The two group discussions were recorded using a digital voice recorder, transcribed in full and then coded using the software program Transana. The discussions were organized into themes, which allowed a basis for the further analysis. The themes allowed us to build a picture of the participants’ views and thoughts on sustainability with regard to their farming management practices in the light of the SAFA framework, and their own thoughts and perception of the government’s action to promote sustainability, as well as to consider its implications for the futures of their own farms. The interviewed beef cattle farmers thought of sustainability on a day-to-day context rather than as a multi-dimensional concept. In their views, sustainability was very much about being able to continue farming, for the farm to survive and about being able to hand it over to the next generation. However, when presented with the four dimensions of the SAFA framework, they acknowledged the wider perspectives and different aspects of sustainability and reflected about how their own agricultural practices related to these wider aspects too.

Abstract

The F94L mutation of the MSTN gene (MSTN-F94L) is considered not to cause disrupted the function of the myostatin gene drastically. Interestingly, this mutation has a very significant effect on muscle mass, carcass, or meat yield and meat quality without any associated severe negative problems. This study aimed to confirm the MSTN-F94L mutation in four local cattle breeds in Indonesia. A total of 518 individuals (140 of Bali, 107 of Sumbawa, 168 of Pasundan, and 103 of Holstein-Friesian (H-F) cattle) were used in this study. Genotype identification was performed by PCR-RFLP method. In the present study showed that the wild-type C allele was fixed (1.000) in Bali, Sumbawa, and HF cattle. However, the wild-type C allele and the mutant A allele were found in Pasundan cattle, even though the frequency of the mutant A allele was very low (0.012). Therefore, in conclusion, the mutation of the MSTN-F94L was detected in Pasundan cattle but no in all three cattle breeds. However, the presence of the mutant A allele in Pasundan cattle allegedly derived from Limousin bulls. The further investigation in other local and exotic breeds and its crossing will answer the status of the MSTN-F94L mutation in local cattle breeds in Indonesia.

Abstract

Birth weight and calving interval are included of productivity traits that can be increased by selection program. However, the standard of desirable birth weight in cattle during the selection program is important to prevent dystocia incident risk. This study was aimed to select Bali cattle (Bos javanicus) based on Estimated Breeding Value of birth weight (EBVBW) and Most Probable Producing Ability of birth weight (MPPABW) and calving interval (MPPACI). Total of 758 records data of BW were collected from Lombok and Sumbawa islands, West Nusa Tenggara Province. Research showed the average of BW in Bali calves were 15.69±1.70 kg (Lombok) and 13.49±1.89 (Sumbawa). The average of CI in Bali cows at both islands were about 385 days. In addition, the heritability (h2) values of BW in both islands was about 0.90. The repeatability (r) values of BW in both islands were about 0.30. Meanwhile, the r value of CI in Sumbawa island was 0.39. The highest of EBVBW for sire was +4.25 kg by bull’s ID: 0838 (Sumbawa). Meanwhile, the highest of EBVBW for calves was +6.07 kg by calf’s ID: 0917 (Sumbawa). The highest of MPPABW was +2.67 kg by cow’s ID: 0872 (Sumbawa). The lowest of MPPACI was -25.70 days by cow’s ID: 02076 (Lombok).

Abstract

The objective of this study was to evaluate the level of organic minerals and total mixed fiber ammoniation (TMFA) as basal feed on the performance of beef cattle. This study used the In Vivo technique and the experimental method using t-test. The t-test compares the best supplementation result on in vitro research and control treatment, each treatment got6 replications. The treatments tested were P1: 60% TMF ammoniation + 15% swamp legume without supplementation of organic minerals P2: 60% TMF ammoniation + 1.5 x Organic macrominerals (Ca, P, and S) NRC (2000) + 15% Swamp Legumes. The parameters measured in the in-vivo technique were nutrient digestibility consisting of dry and organic matters, crude protein, crude fiber, NDF, and ADF. The animal performance: ration and dry matter consumption, body weight gain and ration efficiency. The results showed that supplementation of minerals in rations with TMFA as basal feed had a significant effect (P<0.05) on nutrient digestibility (dry matter, organic matter, crude fiber, NDF, and ADF) and animal performance. The conclusion of this study was supplementation of organic macrominerals 1.5 x (Ca, P, and S) NRC (2000) in a ration with TMF ammoniation as basal feed can improve the beef cattle performance.

Abstract

The study investigated the influence of dietary incorporation of formic acid, butyric acid or their blends on growth rate, haematological indices and intestinal morphometric of broilers. A number of 240 Lohmann MB-202 chicks were pass rounded to four dietary groups, including CONT (chicks taking in basal feed with no additive), BTRT (chicks receiving basal feed with 0.03% butyric acid), FRMT (chicks receiving basal feed with 0.1% formic acid) and BTRT+FRMT (chicks receiving basal feed containing 0.03% butyric acid and 0.1% formic acid). Weight of chicks and intake were measured every week, while blood sample was collected at day 21 and 35. At day 35, birds were slaughtered and small intestinal segments and digesta were collected. At day 21, body weight was bigger (P<0.05) in BTRT+FRMT than in other birds. Feeding the blends of formic and butyric acids resulted in higher (P<0.05) value of mean corpuscular haemoglobin concentration (MCHC) at day 21. Feeding organic acids was associated with the lower (P<0.05) proportion of thrombocytes in broilers at day 35. Supplementation of butyric acid resulted in higher (P<0.05) serum albumin concentration at day 35. Butyric acid produced higher (P<0.05) levels of triglyceride as well as low-density lipoprotein (LDL) in the serum. The mixture of formic and butyric acids resulted in higher (P<0.05) titer of antibody against Newcastle disease vaccine (NDV) at day 21. Feeding formic acid decreased (P<0.05) ileal population of lactose negative enterobacteria at day 35. Overall, dietary supplementation of the blends of formic and butyric acids resulted in improved growth and immune defence of broiler chicks.

Abstract

The study was aimed to evaluate the effect of bio-activator and different fermentation time in the process of producing bio-urine liquid fertilizer (BLF) from Balinese cattle. Two types of bio-activators are used, namely (1) animal bio-activator (ABA) and (2) plant bio-activator (PBA). The time of fermentation process applied is (1) 7, (2) 14 and (3) 21 days. The research was prepared based on a Completely Randomized Design (CRD) of the factorial pattern. The data of the research were analyzed using ANOVA. The result showed that the difference of bio-activator and time of fermentation process had significant effect (P<0.05) on C-organic, N-organic and C/N ratio of BLF, but no significant on pH. The C-organic content of 9.59-12.02%. N-organic of 1.03-1.35% and C/N ratio of 8.33 to 11.03. The pH values are 8.76-8.95. The final results showed that the use of bio-activator using a 14-days fermentation time showed the best characteristics compared to other. The production cost of BLF using PBA is lower IDR.8,179.22 than ABA IDR.8.312,28. The application of PBA IDR.11,820.78, was more advantageous than ABA IDR.11,687.72.

Abstract

This study aimedto identify the SNP g.643G>Aof MYF5 genethen associate it with body weight and body size measurements in Bali cattle. Blood samples were collectedfrom 80 bali cattle at BPTU-HPT Denpasar Bali. Data on phenotypic properties observed included; birth weight, live weight, average daily gain, body length, chest depth, withers height, hip height, and heart girth. Polymorphismof the MYF5 gene was identifiedusing the PCR-RFLP method. Association of MYF5 genotypes with body weight and body size measurementswas performed using General Linear Model by SAS 9.4 program. MYF5│MspI gene was polymorphic with three genotypes: AA, AG, and GG. Genotype frequency of AA, AG and GG were 0.04 (3), 0.30 (24), and 0.65 (53), respectively. Allele frequencies were 0.19 and 0.81 for A and G alleles, respectively. Gene frequency analysis showed that Bali cattle at BPTU-HPT Denpasar was in Hardy-Weinberg Equilibrium. Association of MYF5│MspI gene with body weight and body measurement were not significantly different. SNP g.643G>A could not be used as a genetic marker for the body weight and body size measurements in Bali cattle.
