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.

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.

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).

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

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

The aim of this research was to evaluate the effect of feed restriction on growth hormone profiles and ovarian morphology during the growth period. Three hundred 14-day-old quails were used. The quails were maintained on two feeding restriction programs: two dietary regimes based on metabolizable energy (ME), R1 = 2900 kcal/kg and R2 = 2800 kcal/kg, and 3 quantitative feed restriction diets, P0 = 100% ad libitum; P1= 90% ad libitum and P2 = 80%ad libitum (n=300). Each group (n=50) was processed with five replications, 10 birds in each replicate. The change in growth hormone was determined at 28, 35, 42, and 49 days of age, while ovarian morphology was determined at sexual maturity. The results indicated that feed restriction induced a significant increase in growth hormone and insulin-like growth factor-1 after re-feeding. There was no significant effect caused by the rationing of metabolizable energy. The number of large yellow follicles was not different between quails fed with 100% ad libitum and 90% ad libitum. However, feed restriction significantly increased the number of small yellow follicles. In conclusion, the feed could be restricted to 90% ad libitum with a 2900 kcal/kg ration of ME and fed during the starter period (14 to 42 days of age) without influencing ovarian morphology in quails.
