This study aimed to evaluate the effect of sorghum-Indigofera forage-based feed on the pre-mating performance of Garut ewes. A total of 28 Garut ewes was divided into two groups of treatment so that each treatment consisted of 14 heads. The treatment of field grass (FG) as a control and the feed composition in the formula of 50% sorghum forage silage + 40% Indigofera hay + 10% rice bran (SI). The animals were distributed under a completely randomized design, and the data were analyzed using a t-test. The results showed that the dry matter intake (DMI) and nutrient digestibility values of FG were higher (p<0.05) than SI. However, the impact on body weight gain, blood urea nitrogen (BUN) and blood cholesterol level did not differ (p>0.05). The average pre-mating bodyweight of Garut ewes for all treatments was the same number relatively, were 35 kg/head. BUN and blood cholesterol levels in the FG and SI treatments were 36.18±3.47 vs 35.27±4.23, and 66.13±5.56 vs 69.25±3.95 mg/dl, respectively. It can be concluded that SI feed had higher efficiency values and better readiness for the reproductive phase. Therefore, SI feed can be used as a substitute for field grass for the reproductive stage of Garut ewes.

The length of sexing duration may affect the quality of Bali cattle spermatozoa. This study aims to examine the effect of sexing duration on viability, motility and abnormalities of Bali cattle spermatozoa. This research has been carried out at Regional Technical Implementation Unit (RTIU) Center for Breeding and Animal Feed, Department of Food Crops and Livestock, Southeast Sulawesi Province. The material used was a bull of Bali cattle as a source of semen and spermatozoa to be evaluated. In this study, a completely randomized design (CRD) was used with 3 treatments and 6 replications. The treatments consisted of three different length of sexing duration namely 40 min. (P1), 50 min. (P2), and 60 min. (P3). The variables evaluated in this study included semen quality (volume, color, odor, consistency and pH) and spermatozoa (mass movement, concentration, percentage of motility, viability and abnormalities). The data obtained were analyzed using analysis of variance (ANOVA) and continued with the Least Significant Difference test (LSD test). The results showed that the average volume of Bali cattle semen obtained was 5,38 ml/ejaculate, semen color was milky white, odor was specific, consistency was viscous, pH was 6,3, spermatozoa concentration was 1,445 million/ml and mass movement was +++. Whereas the motility of spermatozoa in each treatment following sexing were 76,67% (P1), 68,23% (P2), and 60,00% (P3). The viability of spermatozoa after sexing were 93,42% (P1), 84,42% (P2), and 79,83% (P3). The abnormality of spermatozoa after sexing were 2,58% (P1), 2,67% (P2), and 2,67% (P3). Furthermore, the results of variance analysis showed that the length of sexing duration had a significant effect (P˂0.05) on the viability and motility of the Bali cattle spermatozoa, but did not significantly affect the sperm abnormalities of Bali cattle. The 40 min. (treatment P1) and 50 min. (treatment P2) of sexing duration resulted in better spermatozoa viability and motility of Bali cattle compared to 60 min. (treatment P3) of sexing duration.Keywords: abnormality, motility, sexing, spermatozoa, viability

This research aimed to ascertain whether dwarf elephant grass (DEG) is compatible to substitute the common forages, viz. elephant grass (EG) and maize stover (MS) in the dairy cow rations (denote as R) using in vitro gas production (IVGP) technique. A completely randomized block design was applied to 4 feeding regimes and 3 replicates, viz. R1 consisted of 40% concentrate (C) + 30% MS + 30% EG; R2: 40% C + 30% MS + 30% DEG; R3: 40%C + 60% EG; and R4: 40% C + 60% DEG. The results showed that rations containing DEG improved both DM and OM degradabilities concomitant with increased in rumen efficiency of microbial protein synthesis (EMPS). Nevertheless, total and potential of gas production (GP) were higher in rations containing MS than other counterparts suggesting that there was a diverting usage of ROMD available for GP and EMPS. In conclusion, the use of DEG in dairy rations is recommended.

Various attempts have been made to maintain the quality of semen by using diluents that are added with appropriate antioxidants to protect spermatozoa from cold shock and maintain the quality of spermatozoa, while the addition of antioxidants in the diluent is useful for suppressing free radical reactions. One of the substances that can be added to cement thinner is L-Argine. The mechanism of action of L-Argine is the same as that of an antioxidant, which is useful in inhibiting free radicals. Nitric Oxide contained in L-Arginine is an antioxidant so that it can inactivate superoxide produced by spermatozoa during the oxygen consumption process. Shelters were carried out 2 times a week with the artificial vaginal method, with 10 shelters during the study. The semen that will be used for research has a minimum individual motility requirement of 70% and a minimum mass motility of ++. The variables observed in this study were abnormalities, intact plasma membrane and intact acrosome cap on observations before freezing and post thawing. The results of the analysis of variance showed that L-Arginine supplementation had no significant effect (p>0.05) on abnormalities in the pre-freezing and post-thawing observations, L-Arginine supplementation had a significant effect (p<0.05) on the integrity of the plasma membrane and acrosome cap. on observation before freezing and post thawing.Keywords: abnormalities, antioxidants, L-Argine, spermatozoa

Banana peel is one of the non-conventional feed ingredients, but its utilization is still limited due to high content of crude fiber and tannins. The usage of 10% tapioca and 21 days of fermentation time in silage production was able to reduce crude fiber and tannin levels of kepok banana peel. A four-week dietary treatment was conducted with 160 day old of joper strain, a cross-bred native chickens, to determine the utilization silage of banana peel (SBP). The birds were randomly assigned to four dietary treatments with five replication of eight chicks each in a completely randomized design. The treatments consisted of banana peel silage inclusion at 0, 10, 20, and 30% in the diet. Data were analyze by analysis of variance (ANOVA) and means were compared using Duncan’s Multiple Range Test. The results showed that inclusion of SBP had significant effect (p<0.05) on weight gain and feed conversion, but had no significant effect (p>0.05) on feed intake. It was concluded that the optimal growth response of broilers was indicated in the inclusion of SBP up to 10% of the diet.Keywords: feed conversion, feed intake, silage banana peel, silage weight gain

This study aims to determine the effect of using the collagenase enzyme on the viability of chicken embryos' liver, kidney, and fibroblast cells in vitro. Liver and kidney organs were collected from embryonic chicken eggs at 15 and 19 days. Meanwhile, fibroblast cells were obtained using muscle tissue of 11-day-old chicken embryos. Each organ and tissue was chopped and incubated using 0.1% trypsin for 10 minutes and 0.1% collagenase for 30 minutes. Concentration, viability, and proliferation rate were calculated after incubation and analyzed using a t-test. The results showed that there was a significant increase in the tissue incubated with collagenase on the viability and proliferation rate of liver cells, kidney cells, and chicken embryo fibroblast cells (t<0.05), and not significant in the acquisition of cell concentrations (t>0, 05). Cell isolation and purification techniques need to be carried out to study the quality of somatic cell culture of chicken embryos more specifically.Keywords: collagenase, trypsin, chicken embryos, viability, cell culture.

ABSTRACTThe edible film is a thin layer that can be produced from edible macromolecules. One of the ingredients for the edible film is gelatin from chicken bone waste which can be obtained from slaughterhouses. The edible film can be combined with other components such as antimicrobial substances found in tea plants. This study aims to determine the effect of variations in heating temperature and the addition of tea extract as an antimicrobial edible film. Research parameters include water content, total phenol, and zone of inhibition. The experimental design used was a factorial completely randomized design with 2 treatment factors, namely X = additional concentration of tea leaf extract 0%, 20%, 25%, 30%, and 35% and Y = variations in heating temperature of 70⸰C and 80⸰C, each treatment was repeated 2 times. The data obtained were analyzed by ANOVA and if there was a significant difference between treatments, it was continued with the DMRT test (Duncan Multiple Range Test). The results of this study indicate that variations in heating temperature have no significant effect on water content, total phenol, and antimicrobial edible film inhibition zone. The highest water content value was 21.12% at a heating temperature of 70⸰C and the tea extract was 30%, the highest total phenol value was 13.01 g GAE/g obtained at 30% tea extract concentration and the highest inhibition zone was at 30% tea extract concentration. with a value of 1.97 cm.Keywords: Antimicrobial edible film, tea extract, gelatin, heating temperature
