    The objective of the present study was to determine the effects of Merino rams on the in vitro motility, velocity and capacitation status of ram spermatozoa. Four rams of proven fertility were used in this study. Semen was collected by electro ejaculation. The fresh semen was diluted at four dilutions in Hepes buffered synthetic oviduct fluid. A sample of semen was collected and the motility, velocity and capacitation status of spermatozoa determined and analyzed. The results study showed that motility and velocity of Merino rams spermatozoa were not significantly different. The mean average path velocity (VAP), straight-line velocity (VSL) and curvilinear velocity (VCL) were 91.2 µm/s, 72.2 µm/s and 134 µm/s, respectively. Amplitude of lateral head displacement (ALH), beat cross frequency (BCF) and linearity (LIN) was 5.5 µm, 19.5 Hz, and 54.7%, respectively. During the incubation time, progressively more spermatozoa became capacitated such that at the end of the incubation, 40.9±0.9% was capacitated acrosome-intact and 29±2.5% was capacitated acrosome-reacted. In conclusion, the motility and velocity of Merino spermatozoa were similar among rams. There were differences among rams in the capacitation profile; however there was no significant effect of incubation time and dilution rate on the capacitation status. Keywords: Merino rams, spermatozoa, motility, velocity, capacitation in vitro Animal Production 14(2):104-11

    Objective of this research was to study the effects of graded level supplementation of ammoniated zeolite on rumen metabolism parameters. This in vivo experiment was conducted in a 4x4 latine square design (LSD) with 4 treatments in 4 periods, using 4 crossbreed etawa male goats.  The treatments were T1 = basal diet + 0% ammoniated zeolite, T2 = basal diet + 2% ammoniated zeolite, T3 = basal diet + 4% ammoniated zeolite, and T4 = basal diet + 6% ammoniated zeolite.  Level of ammoniated zeolite supplementation is based on dietary dry matter basis. The basal diet consists of 70% Napir grass and 30% concentrate.  Each period of experiment consist of 2 weeks for adjustment, 1 week for preliminary, and 10 days for total collection.  Result of the experiment showed that ammoniated zeolite supplementation significantly increased the total volatile fatty acids concentration and total organic acids concentration in the rumen.  Improved total volatile fatty acids concentration in the rumen could be used as a good indicator for improving rumen metabolism.  However, even the concentrations of ammonia in the rumen tend to increased by ammoniated zeolite supplementation the increasing is still not statistically significant. Ruminal pH measurement in this experiment revealed that the use of ammoniated zeolite not significantly affects the ruminal pH.Key Words:  ruminant, ammoniated zeolite, ruminal ammonia, volatile fatty acids, organic acidsAnimal Production 13(3):138-142 (2011

    Abstract. The objective of the current study was to find out the litter size and lamb survivability of Batur sheep, and also to identify the effects of ewe parities on litter size and lamb survivability; and the effects of birth type on lamb survivability of Batur sheep. The study was conducted at the Batur sheep Farming Group in the upland areas of Banjarnegara regency, Central Java province of  Indonesia.   Data from 311 records of lambing of Batur sheep at the village breeding centre for Batur sheep were analyzed. Least squares procedure by the General Linear Model was used to identify the effect of parity on litter size at birth and at weaning. Preweaning survivability was analyzed using the Chi-squares. Results showed that average litter size at birth and at weaning, and lambs survivability till weaning were 1.55±0.03 and 1.36±0.03 lambs; and 88.42%, respectively. Litter size at weaning and lambs survivability was significantly different among ewe parities, and increased by advancing ewes parities. Its indicating that age of ewe was important factor for the success in early stage for producing lamb. Survivability of single lamb (93.62%) was significantly higher that twins (84.11%). Increased care for twins by providing proper management might lead to a recognizable increase in lamb survival and flock productivity of Batur sheep.Key words: Batur sheep, litter size, lamb survivability, parity, preweaningAnimal Production 13(3):166-172 (2011

    Abstract. This study evaluated sheep fattening and goat breeding innovation scenarios for small ruminant systems in Central Java. In sheep fattening scenario 1, farmers were proposed to fatten 5 male sheep two times a year, in sheep fattening scenario 2, farmers were proposed to fatten sheep in one round of 9 months up to the age of one year. In sheep fattening scenario 3, farmers were proposed to fatten male sheep in two periods, one round with 5 animals as in scenario 1, and another round with 5 animals sold at one year of age for Idul Adha. Goat breeding scenarios were based on a breeding unit with 3 does and involved reductions of kidding intervals from 278 (middle zone) and 273 (uplands) days to 240 and 220 days. The sheep fattening scenarios indicated that if farmers could start specialising in sheep fattening, the technical and economic results could be improved compared to the present sheep production system. Sheep fattening scenario 3 showed the highest net live-weight production in kg and the highest value added. When the opportunity labour costs were included in the calculations, fattening of sheep still produced a positive net return to the farmers. A goat breeding unit with 3 does produced 2.2 and 1.7 times more kids than in the real situation in the middle zone and uplands, respectively. Reducing kidding intervals resulted in an increase of kids sold by 1.2 and 1.3 respectively for kidding intervals 240 and 220 days in the middle zone; while in the uplands this was 1.1 and 1.3 times respectively. The breeding scenario calculations indicated that goat breeding could make a positive contribution to the livelihood of goat farmers, if the management of goats was improved.Keywords:  sheep fattening, goats breeding, value added, IndonesiaAnimal Production 14(1):37-46, January 201
