This study was conducted to determine the response of superovulation by giving 16 ml dosage of FSH hormone to female Pesisir cattle. The estrus schedule of 15 Pesisir cows was set by inserting CIDR (Controlled Internal Drug Release) into the vagina for 12 days. At day 10, all cattles were injected with FSH for three consequent days but with decreasing dosage. On the 3rd day, FSH injection was accompanied by PGF2α injection and CIDR was removed. The detection of estrus was performed at day 13. Natural mating was proceeded after the estrus signs visible. Collection of donor embryos was done on the 6th and 8th day after mating. The variables measured were the response of superovulation, total number of corpus luteum, number of embryos and sex ratio. The results obtained were all Pesisir cows responded to superovulation. The average number of of corpus luteum and embryoes per cow were 5.93±3.17 and -----, respectively, while the total of transferable embryoes were 90, with an average of 6.00 or 61.64%. The sexing of embryoes obtained in this study from 146 embryoes awere 76.03% males (111 embryoes) and 23.97% females (35 embryoes). Based on total of transferable embryoes, there were 51.37% male embryos and 11.28% of females embryos. The result of this study showed that the sex ratio of male embryos was higher than female embryos.

A research with the aim of obtaining an effective combination pattern of fertilization management was done on mulato grass plants (Brachiaria Hybrid cv "Mulato"). The used fertilizers were of cow dung that serves to maintain the quality of soil and urea that is useful to increase the growth and production of plants. The method used was Completely Randomized Design where the treatments were mixed dairy cattle dung at 10, 17 and 24 tons per hectare per defoliation and urea fertilizer at doses of 75, 150 and 225 kg per hectare per defoliation. Each treatment was repeated 3 times so that there were 27 plots of research. The parameters studied were plant height, tiller number, leaf number, weed population and fresh forage production. The collected data were analyzed based on Completely Randomized Design, between Orthogonal tested treatment and regression analyzed dose. The results showed that the combined treatment of cow dung as much as 24 tons per hectare per defoliation with urea of 225 kg per hectare per defoliation (K3U3) showed the best growth and production of Mulato grass, while for the given dosage yielded a linear regression equation

Cholesterol consumed more than required body will influence health problem such as arteriosklerosis and finally resulted in coronary hearth. The purpose of this study is to evaluate the concentration of cholesterol and fat abdomen local chicken administrated various levels of feed additives. Totally 200 chickens from growth study were selected for 20 chickens at the age of 90 d for further cholesterol and fat abdomen analysis. This study was designed by using completely randomized consisting of 4 treatments and 5 replications. Four treatments in this study was administration of feed additives either in the water or in the feed (A0 = control-vita chick 0.7 gram/liter; A1= 20 ml/liter probio-FM; A2= 0.08% MOS (manan-oligosakarida)/kg in feed and A3= herbal leuser KI 5 ml/liter). Variables observed in this study were the content of cholesterol and fat abdomen. All data were statistically analyzed using SPSS and differences between treatments were stated (P<0.05) by using Duncan Multiple Range Test (DMRT). The results of the study indicated that administration of various feed additives significantly effected (P<0.05) on the cholesterol content of breast meat of local chickens. The average of breast meat cholesterol content was 52 mg/100g, 44 mg/100g, 43 mg/100g and 46 mg/100g for A0, A1, A2 and A3 respectively. Administration of administration of various feed additives significantly reduced (P<0.05) the percentage of fat abdomen of local chickens with the percentage of 0.78%, 0.36%, 0.27% and 0.42% for A0, A1, A2 and A3 respectively. This study concluded that administration various feed additives significantly reduced cholesterol content and the percentage of fat abdomen with the lowest of cholesterol content 43 mg/100g and the lowest percentage of fat abdomen 0.27% for prebiotic treatment.

his research was conducted to evaluate the effect of turmeric water extract, garlic and combinations of turmeric and garlic as feed additives in broiler diets on the physical and sensory quality of broiler meat. During the study, the chicken were given 5 feeding treatments, i.e. R0 (basal ration without phytobiotic and antibiotics) , R1 (basal diet + 0.015% zinc bacitracin + 2.485% filler), R2 (basal ration + 2.50% TE), R4 (basal ration + 2.00% GE + 0.50% filler), and R5 (basal ration + 2.50% TGE). The base diet was composed of: yellow corn, meat and bone meal, poultry meat meal, soybean meal, oil, mineral mix, calcium carbonate, dicalcium phosphate, salt, L-lysine-HCl, and DL-methionine. Variables observed were physical quality (pH, water holding capacity, cooking lose, and tenderness) and sensory quality. Data regarding physical quality were statistically analyzed by one-way ANOVA followed by the orthogonal contrast for significant results, and data of sensory quality by non-parametric methods such as the Hedonic Kruskal-Wallis test. The results showed that the physical quality of meat had no effect (P>0.05), except the significant water holding capacity (P<0.05) which was lower with phytobiotic extract supplementation. All sensory test parameters in fresh and cooked meat had no effect (P>0.05) following phytobiotic extract supplementation, except for the color and acceptability (P <0.05) in fresh broiler meat. The conclusion of the research was that 2.5% TE, 2.0% GE and 2.5% TGE is capable of acting as a feed additive to increase the physical and sensory quality of broiler meat.
