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

The study aims at determining the level of behavior and cattle farmers expectation for using cattle as agro touristattraction, analyze the cattle breeders income and the relationship between breeders behavior and expectationincluding their perception of agro-tourism activities using cattle as attraction. It was conducted at Penebel andMarga districts, Tabanan regency. The respondents were collected as quota; 50 breeders were interviewed in 6agro-tourism places such as Somya Pertiwi and Jatiluwih, Taman Sari Buana, Rumah Desa, tourist village of Pinge,and Cau Coklat. The data was analyzed in descriptive qualitative and correlation analysis. It showed that 1) farmersbehavior towards the existence of agro-tourism using cattle as tourist attraction considered to be good; 2) income offarmers participation using cattle as tourist attraction range between Rp. 50.000 - and Rp. 300.000,- in ploughingactivity, and 3) positive relationship between farmers behavior and expectation and their perception towards thedevelopment of agro-tourism business who use cattle as attraction. It can be concluded that 1) breeders have goodbehavior towards the development of agro-tourism business; 2) breeders gained extra income by participating inagro-tourism activities in order to achieve income by selling their cattle; 3) breeders have better behavior and higherexpectation which is the better perception towards the use of cattle in agro-tourism business activities. Finally,suggestions such as 1) investors in agro-tourism business should co-operate with famers in their surroundingsto run the activities; 2) Breeders should encourage raising cows instead of bulls since they are tame and increasepopulation of cattle in their area; 3) local government should play important role in development of agro-tourismbusiness i.e. village roads construction so it can encourage the visitors to come to the location. All of those willpositively affect the prosperity of local breeders

Abstract

Nutrition in eggs is very important to know to improve the public health. This study aims to determine the effect of the level of extract of garlic water (Allium sativum) on protein, fat and cholesterol contents of laying chicken eggs of Lohmann Brown aged 22-30 weeks. This research was conducted for 3 months at laying chicken farm in Dajan Peken Village, Tabanan Subdistrict, Tabanan Regency. 36 laying chickens of Lohmann Brown with a homogeneous weight were raised in 18 squares of colony batray cages. The design used in this study was a complete randomized design (RAL) with 3 treatments and 6 replications.The treatment consisted of drinking water without additional garlic water extract (B0) as control, drinking water with 3% extract of garlic water (B1), and drinking water with additional garlic extract of 6% (B2). The variables observed in this study were dry weight of egg yolks, egg yolk protein content, fat content and yolk cholesterol content. The results showed that on treatment of B1 and B2 significantly (P <0.05) increased the yolk protein content compared with B0 as the control. But in the fat content and yolk cholesterol decreased compared with chicken that was not given garlic water extract (Allium sativum) B0 as control. From the results of this study, it can be concluded that the giving of garlic extract (Allium sativum) with 3% level and 6% through drinking water can increase protein content and decrease fat content and cholesterol of chicken egg yolks of Lohmann Brown aged 22-30 weeks. Keywords: Lohmann Brown chicken, egg yolk, and garlic water extract.

Abstract

Heritability is one of the genetic parameters which is requiredforselection. It is influenced by genotipic and phenotipic variations. Balai Pembibitan Ternak Unggul dan Hijauan Pakan Ternak (BPTU-HPT) Denpasar is goverment institution which is responsible to do breeding program in Indonesia.The purpose of this study was to find out the variation of heritability values of birth, weaning, and yearling weight of Bali cattle in BPTU-HPT Denpasar from 2012 to 2015. Model applied to predict the heritability value in this study was "Unequal numbers of progeny per sire"(Becker, 1985). The data used in this study was birth,weaning, and yearling weight data from 2012 to 2015.Data was analyzed with SPSS 24.0. In addition, heritability value was calculated with h2= 4?2s/?2s+?2w (Becker, 1984) formula. The results showed that the heritability of birth, weaning and yearling weight were vary from negative to positive. Negative value due to less number of bull used inthe population. Keywords: Bali Cattle, Heritability, Body Weight
