ABSTRACT
This research was conducted to determine the effect of adding hormone FSH and PMSG in vitro oocyte maturation medium on maturation rate and hormone progesterone. In this experiment, oocytes derived from ovaries of slaughtered cattle at the slaughterhouse. Maturation medium using TCM-199 supplemented serum 10%, gentamicin 50 ug / ml, FSH 10 g / ml or PMSG 10 g / ml and the culture of granulosa cells 1x105 cells / ml. In each treatment unit is used 20 oocyte quality A and B in 100 mL of maturation medium. Randomized Blok Design in factorial (2x2x4) was used in this experiment. The Factor A culture (without cells and granulosa cells), B factor hormones (PMSG and FSH).Variables measured were the number maturation and progesterone hormone levels in maturation medium by using RIA techniques. The results shown, there is no interaction of hormone addition in granulosa cell numbers on maturation level and progesterone concentration  in maturation medium. Granulosa cell in maturation medium significantly (P<0.05) increased the number of oocyte maturation in vitro. The highest maturation was obtained from  media with granulosa cells and FSH of 71.25%, while the highest progesterone obtained from media with granulosa cells and PMSG 1.40 ng / ml.

ABSTRACT
West Java is an imported-beef feedlotter region. Almost 50% of imported cow from Australia are cattled in several district and city. The ammount of cattled imported beef increases every year. Its shows that the implementation of import policy has not been optimal. It did not develop the business of local cattle production. The condition was suspected because of lack of effective implementation of policies by the authorities. This study aims to analyze how the varied pattern of the implementtation of beef import policy reviewed from the aspect of communication, resources, disposition and bureaucratic structure. Research conducted in fifteen distric and city in West Java. This research used the survey method, multistage random sampling, analyzed by using the model of Edward to measure the level policy implementation. The result are, (1) there were pattern variations in import policy implementation: 2) In general, implementation of the import policy, varies from moderate to good. 3) Implementation from the province into districts varies with the medium pattern. 4) Sukabumi, Ciamis and Bandung district is better than the other several district and cities in West Java. Conclussion: policy implementation not yet effective and differs depending on resources.

ABSTRACT

The Pesisir cattle are indigenous West Sumatera cattle. Their quality needs to be improved since they can live in local environment with sufficiently available feed resources. A research has been done to study the effects of feeding level and fattening period to the growth and the carcass characteristics of the Pesisir cattle. This research was designed by using block design with three blocks. The first factor was two levels of feeding, i.e: A1 = 50 % concentrate + 50 % ammoniated rice straw, A2 = 75 % concentrate + 25 % ammoniated rice straw. The second was time period of fattening, i.e: B1 = 3 months and B2 = 4 months. The results showed that there was no interaction between the level of feeding and fattening period to the growth, percentage of carcass, the back fat thickness and the rib eye area of the Pesisir cattle (P> 0.05). The higher of concentrate percentage, the higher the growth of the cattle, the thicker the back fat and the wider the rib eye area will be (P<0.05). Similarly, the longer the fattening, the higher the percentage of carcass, the thicker the back fat and the wider rib eye area will be.

ABSTRACT

The purpose of this study was to obtain the level of supplementation of cassava leaves as a source of branched chain amino acids in improving nutrients digestibility of ammoniation palm leaf, and characteristics of rumen fluid ( in-vitro). The experiment was designed by using randomized block design with 6 treatments of supplementation of cassava leaf (A = 0% as control, B = 5%, C = 10%, D = 15%, E = 20% and F = 25% of dry matter) with 4 replications. Parameters were: 1) Digestibility of nutrients (dry matter, organic matter, crude protein) 2) Digestibility of fiber fractions (NDF, ADF, cellulose and hemicellulose) and 3) Characteristics of rumen fluid (pH, NH3, and VFA) by in- vitro. The results showed cassava leaves supplementation significantly (P <0.05) increased the in-vitro digestibility of palm leaves ammoniation. The highest dry matter digestibility obtained at cassava leaf 5% (24.09%) in comparing controls (45.49% vs. 56.45%), and ADF digestibility increased by 36.91% compared to controls (37.25% vs. 51.00%). Cassava leaves maintained rumen fluid characteristics for microbial rumen growth and activities. It concluded, the level of supplementation cassava leaves as a source of the best branched chain amino acids in palm leaf ammoniation was 5%.

ABSTRACT
The research purpose was analyzed the utilization of production factors in dairy cow farming in economies of scale at Ompie dairy cow farming in Tanjung Bonai village, North of Lintau Buo subdistrict, Tanah Datar regency. The samples were 18 lactating dairy cows. Data obtained through case study by observing and calculated the consumption of grass and concentrate as well as the lactating month and the cow’s weight directly, and interviewed Farm’s caretaker. Production factors estimated by using ordinary least square by using SPSS 17. Result shown, production function Y= 0,0012 H1,671K0,405M-0,187W0,119 was obtained. R Square test determination, coefficient (R2) was 0.721, which was means 71,2% of production variation can be explained through green food variable, concentrate, month of lactation, and different cows’ weight. The F test showed that overall, independent variables has significant impact on milk production (P<0,01). The t test result showed that green foods variable and month of lactation has real impacts on level of trust 99% while concentrate and cow’s weight did not have significant impact. This farm is experiencing increasing return to scale which means increasing the amount of input will generate additional output with bigger proportion. We can observe this on Σbi value of 2,076.
