Abstract

This study was carried out at Bali Cattle Breeding Centre (BPTU Sapi Bali) in Pulukan, Jembrana, Bali from March to November 2012. The aims of study were to estimate the heritability and genetic response to selection for yearling weight in Bali cattle. Records on 350 yearling weights of Bali cattle born from 2007 to 2011 at the Bali Cattle Breeding Centre were used in this study. The results showed that the average coefficient of variation for yearling weight of Bali cattle was 18.28%, the estimated heritability (h2) was 0.42 ± 0.19, and the selection intensity was 0.92.  This value ??indicated that selection for this trait might improve the genetic quality of Bali cattle particularly in their liveweight at one year old.  Estimation of genetic response (Rg) obtained in this study was 9.02 kg.  The average generation interval in this population was 4.48 years.  Therefore, response per year (Ry) for yearling weight in this breed of cattle was 2.01 kg.  Based on this response per year, prediction for response in the year 2010 and 2011 were 6.03 kg and 12.06 kg respectively.  It was concluded that the heritability estimate of yearling weight in Bali cattle was categorized high and selection for this trait responded effectivelly

Abstract

An experiment was carried out to study the  levels of blood and meat cholesterol of male bali duck fed commercial diets supplemented papaya leaf (Carica papaya L) meal, in the Bali Provincial Laboratory. The design was completely randomized design (CRD) with 4 treatments and 5 replications. The fourth treatment were100 % commercial ration without papaya leaf meal (A) ; 98% commercial ration supplemented 2% papaya leaf meal ( B ) ;  96% commercial ration  supplemented 4 % papaya leaf meal (C) and 94 % commercial ration supplemented 6 % papaya leaf meal (D). The variables measured were total cholesterol, triglycerides, LDL and HDL blood and meat of male bali duck. The results showed that papaya leaf meal supplemented in the commercial ration from 2-6 % can significantly reduced total cholesterol, triglycerides and LDL, and increased HDL blood and meat of male bali duck. From the results of this study it be concluded that papaya leaf meal supplemented in commercial ration 2-6 % can reduced total cholesterol, triglycerides and LDL, and increased HDL blood and meat of male bali duck.

Abstract

Water is well thought-out as one of the basic need of human life. Beside its significant role in incomecontribution in the region, tourism industry is almost blamed as an environmental demolisher and polluter inBali. This matter writer interest for research something result quality waste water processing at one casehotel and specific as know bacteriology and chemistry quality, because the result of quality hotel waste waterprocessing very influential about water of river already polluted as physical, chemistry and bacteriology.The study aimed to investigate water quality of Ayung River at the nearest outlet of a star hotel STP and atupper-site rive..The research of methodology is hotel waste water analysis be based on the Minister of EnvironmentLife Regulation number 52, 1995. Analysis result waste water process and water ofr river be based onGovernment Regulation number 82, 2001.The water analysis results evidently showed that water sample taken during the 1st - 3th weeks beforeprocessing at hotel’s STP were classified as heavily polluted based on water quality class I, II, III, and IV,with lowest pollution index (PI) of 33.23 and highest at 42.56. Amazingly, samples taken after STPprocessing were categorized as heavily polluted as well, based on water quality class I II, III, and IV. Thelowest PI was 13.4 and the highest at 22,15. Water sample taken at the nearest STP outlet at river wascategorized as slightly polluted based on water quality class I and fill quality criteria based on water qualityclass II, III, and IV. Water sample taken at upper-site of Ayung River was categorized as slightly pollutedbased on water quality class I, and fill quality criteria polluted based on criteria of water quality class II, III,and IV.
