Myostatin (MSTN), a member of the transforming growth factor β (TGF-β) superfamily, is a negative regulator of skeletal muscle growth. Improving muscle growth is very important to increase the economic value of Indonesian indigenous chicken especially in sentul chicken. This study was aimed to identify the polymorphism of the Myostatin gene in sentul indonesian indigenous chicken with maternal immunization against Myostatin on post hatch and to evaluate its effect on carcass traits. In this study, 48 Sentul hens for up to 6 months have been divided into three groups with 16 birds in each group: CON, KLH, and KLH-MSTN. The CON group has not received immunization, the KLH group has been immunized with 1 mg of KLH, and KLH-MSTN has been immunized with 1 mg of KLH-MSTN conjugate intramuscularly. The effects of each group have been observed on F1 carcass production.The gene polymorphism was identified using PCR-RFLP and the effect of genotype on carcass chacteristics were analyzed using SAS General Linear Model Procedure. The product of amplification was 247 bp. This locus was polymorphic in sentul chicken with two alleles (G and T) and three genotypes (GG, GT, TT). Association analysis were not significant in carcass characteristics. The result of this study showed that interaction of each group with genotype not significant on carcass weight of F1 chicken sentul each age group. F1 sentul chicken 12 week-old significant association of genotype was observed only in thighs weight while 20 week-old was significant in live weight, carcass weight, breast weight, wings weight, thighs weight, drum sticks weight, breast muscle weight, thighs muscle weight and drum sticks muscle weight. These results suggest that no effect genotype on maternal immunization against myostatin to stimulate carcass characteristic in sentul chickens.

The objective of the study was to determine the effect of Moringa oleifera supplementation via Urea Molasses Multi-nutrient moringa Block (UM3B) on consumption and digestibility of dry matter and organic matter in the Bali cattle. A total of 16 Bali cattle aged 2-4 years, of same sex ratio, body weight around 200-250kg was used in this study. The cows were allotted to four equal groups that were placed in individual cages rendered to the distribution of treatment groups. The feed was given in the form of field grass and concentrate. The treatment in the first group (P0) was given UMMB (Urea Molasses Multi-nutrient Block) without moringa, while the second (P1), third (P2) and fourth (P3) groups were given UM3B with 5, 10 and 15% of moringa respectively. The consumption of dry matter and organic matter in the Bali cattle was not significantly different (P>0.05) between control (P0) and all treatment groups. Whereas, the percentage of digestibility of organic matter, as well as, percentage of digestibility of dry matter were significantly different (P<0.05) between control (P0) and treatments of P2 or P3.It is concluded that the consumption, as well as the digestibility of dry matter and organic matter were improved by supplementation of moringa and the best results were obtained at 15% inclusion of moringa in UM3B.

DOI: 10.9775/kvfd.2017 AbstractThis study was conducted to investigate the effect of fish oil addition to the semen extender on post-thaw quality of Bali bull spermatozoa. Fish oil was added at the doses of 0 (control), 50, 100, 150 and 200 mg/100 mL to the skim milk-egg yolk extender. Supplementation of fish oil at the dose of 100 mg/mL significantly (P<0.05) increased both live sperm rate and motility, but its dose of 200 mg/mL caused a significant (P<0.05) decrease in the live sperm rate when compared with the control group. A significant (P<0.05) increment was observed in abnormality rate of frozen-thawed spermatozoa in comparison with the control group when all doses of fish oil except 50 mg/100 mL were added. In conclusion, addition of 100 mg fish oil to 100 mL of skim milk-egg yolk extender could be beneficial for the improvement of the quality of Bali bull spermatozoa after freeze-thawing.

Süt tozu-yumurta sarısı sulandırıcısına 0 (kontrol), 50, 100, 150 ve 200 mg/100 mL dozunda balık yağı ilave edildi. 100 mg/100 mL balık yağı ilavesi kontrol grubu ile karşılaştırıldığında hem canlı sperm oranını hem de motiliteyi önemli derecede (P<0.05) artırdı, ancak 200 mg/100 mL'lik doz canlı sperm oranında önemli (P<0.05) bir azalmaya neden oldu. 50 mg/100 mL'lik doz hariç balık yağının tüm dozları ilave edildiğinde kontrol grubuna kıyasla dondurulmuş-çözdürülmüş spermatozoonların anormallik oranında önemli (P<0.05) bir artış gözlendi. Sonuç olarak, süt tozu-yumurta sarısı sulandırıcısının 100 mL'sine 100 mg balık yağı ilavesi Bali boğa spermatozoonlarının dondurma-çözdürme sonrası kalitesinin artırılması için faydalı olabilir.

Duck eggs  that are often processed into salted eggs. But now it is necessary to look for other alternatives from processing these duck eggs with different tastes, besides taste salty there is also a sense of smoked.This study aims to analyze the effect of fumigation media on the exterior quality and organoleptic of salted smoked eggs. The method was used an experimental method. Fumigation was carried out 48 hours for each fumigation media. The research method used a Completely Randomized Design (CRD) with five treatments and four replications (5x4) in a total of 20 research units consist of m0 = no fumigation (control), m1 = fumigation media using coconut fiber, m2 = fumigation media using sawdust, m3 = fumigation media using rice husk, and m4 = fumigation media using galam bark. Exterior quality data obtained were carried out by homogeneity test data and ANOVA. If the analysis of variance is significantly different or very real it's done by means of the middle value test using the Duncan Multiple Range Test (DMRT). While the analysis of the organoleptic test results obtained was performed using the Kruskal Wallis test then Duncan Multiple Range Test (DMRT). The results showed that the fumigation media effected to the sand and the typical aroma of salted smoked eggs. The fuming media acts on the weight reduction of salted smoked eggs. Galam bark fuming media and coconut fiber has the highest sandiness among other media. However, the smoked media from galam bark had the biggest egg weight shrinkage.
