This research aimed to find out the genetic progress for Aceh cattle by several growth traits selection such as birth weight (BW), weaning weight (WW), yearling weight (YW), mature weight (MW) of does to identify the best selection response from bulls and cows breeding patterns. The recorded data of production and reproduction of Aceh cattle from 2010 to 2014 at breeding centre were analyzed and used as a technical coefficient on estimate heritability (h2), genetic correlation (rG), direct selection response (RY) and correlated selection response (CRY) on several breeding patterns. Most of h2 and rG value among growth traits were positive and high. The highest value of Ry found on BW (0.04), WW (1.21), YW (2.05), MW (3.28) and this was obtained on breeding pattern for 3 years and cow for 6 years. The indirect selection or CRY value based on BW were lower than WW. It is concluded that WW might be used as selection criterion in order to increase WW, YW and MW.

Sapindus rarak fruits have bioactive compound named saponin which are potential to inhibit growth of protozoa and reduce cholesterol. This study was conducted to evaluate effect of lerak (Sapindus rarak) powder as microparticle on performance and lipid profile of chicken broiler that was infected by Eimeria tenella. A total of150headsof DOCwere assign to recive on of5 treatments: T1 (K+, TAk, TSRa, TIE), T2 (K-, TAk, TSRa, IE), T3 (Sal, IE), T4 (Sra 2,5, IE), and T5 (Sra 1,25, IE); each treatment consisted of 6replications with 5birds per replications in battery cage for 34 days. All chickens except those in control positive treatment (non-infected, non-medicated) were inoculated orally with 6000 oocysts E. tenella on the 14th day of age. Variables measured were body weight gain, carcass, OPG (oocysts pergram of faeces), lipid profile, and mortality. Treatment with S. rarak, dose of 1.25g/kg was not significantly different from the salinomycin treatment on BWG and feed conversion. Percentage of carcassand organs and blood cholesterol concentration were not significantly differentin all treatments, but blood triglyceride at S. rarak addition with doseof 2.5, 1.25g/kg and salinomycin addition with dose of 0.5g/kg, and negative control were lower than positive control. While number of OPG in faeces (days 14-34) showed that S. rarak powder with dose of 2.5 and 1.25g/kg suppressed the development of oocystsof E. tenella. In conclusion, S. rarak microparticle (75µm) can be used as feed additive to replace salinomycinas coccidiostat.

One of energy sources for feeding dairy cow is fat or oil, however, inclusion of fat or fatty acid at high level (>5% in the diet) may cause negative effect on rumen fermentation. Fat or fatty acid, therefore should be protected from its degradation in the rumen. The aim of this experiment was to evaluate protected product of palm oil fatty acid (Calcium fatty acid) made in the institute as feed supplement given on top of the ration. The first experiment was in vitro experiment using rumen liquor. Feed without and with Calcium fatty acid (Ca-FA) was incubated in buffer-rumen liquor and pH, total gas, ammonia and in vitro digetibility were measured. The second experiment was feeding trial with two treatments using 12 FH dairy cow divided into 2 groups with diet containing supplemntation 300 g of Ca-FA and other group is control treatment without supplementation. The feed was total mixed ration, comprises of elephant grass, ground corn, soybean meal, wheat pollard and coconut meal with protein content 15.1% and Net Energy for Lactation 1.53 Mcal/kg.. Feed was given to cow one month before parturition until 120 days of lactation period. Milk production was recorded daily. Faeces collection was done at the end of the experiments for 1 week to calculate total tract digestibility. The result of the in vitro experiment showed that no negative effect on in vitro rumen fermentation except higher digestibility (DMD Ca-FA addition vs control were 58.52% vs 53.99%) occurred due to addition of Ca-FA. The addition of Ca-FA increased milk production (11.41 vs 10.74 litre/day), but no effect on intake, total tract digestibility and milk quality, higher body weight of cow than control cow showing the benefit of using Ca-FA in the diet of dairy cow. In conclusion supplementation of Ca-FA at 300 g would be beneficial to increase milk production without negative impact. Key Words: Calcium-Fatty Acid, Dairy Cow, Milk, Production, Quality

This study is to investigate the residue level of TCDDs/TCDFs in beef collected from Animal Slaughter Houses in Giwangan (Yogyakarta), Klaten (Central Java) and Kupang (East Nusatenggara). Residue of persistent organic pollutants (POPs) was also analysed with GC-ECD, and dioxins with GC-MSMS. Fifty samples were collected form Giwangan (20), Klaten (15) and Kupang (15). Results shows that POPs were detected in beef samples including aldrin, dieldrin, DDT, endrin and heptachlor. The highest total residues of POPs were detected in beef from Giwangan (Yogyakarta) at 93.11 hg/g, followed by Klaten (17.79 hg/g) and Kupang (12.87 hg/g). Residues of POPs were below the maximum residue limit stated by the SNI 7313: 2008. Average of total TEQ for TCDDs/TCDFs in beef from Giwangan was 13,624.38 rg/g with a range between 4,496.66 to 20,642.40 rg/g was higher than that from Kupang at 1,623.98 rg/g with a range between 0.83 to 6,471.07 rg/g. On the other hand, dioxins were not detected in beef from Klaten. The total TEQ of TCDDs/TCDFs in beef samples from Giwangan was 54,497.52 rg/g and Kupang was 6,495.9 rg/g. These results indicated that there was an association between the presence of endrin and heptachlor with the presence of TCDDs/TCDFs residues in beef that this is may be new information for further studied.
