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

Closed house waste which has so far been considered a contributor to environmental pollution if processed professionally, can be reused as a component of non-ruminant rations. The purpose of this study is to determine the production (potential, quantity, and quality) of broiler farm waste that is maintained in a closed house system. The cost of production of non-ruminant livestock (pig) 70-80% is still occupied by the cost of feed. The price of commercial concentrate is relatively expensive, which is a reason to look for alternative feed sources. The discovery of potential closed house chicken farm waste and innovative products as a source of protein in rations for non-ruminant (pig-poultry) is expected to the feed problem. Innovative product protein concentrate chicken farm waste of closed house (WCH) system that is cheap and competitive is produced through three stages of research: identify the type and availability of waste, its nutrient content, formulate various protein concentrate formulas, and small-scale tests on pigs with metabolic cage to determine metabolized energy content and digestibility. The results showed that the type of closed house waste (WCH) that has the potential as alternative animal feed is the waste of dead-refused chickens, and litter mixed with scattered feed. Production data in 4 periods of rearing, obtained the number of dead and rejected chickens weighing 850.7 kg (212.7 kg/period), and litter weight of 4000 kg (1000kg/period). Nutrient content of flour mixed with closed house waste (WCH), protein: 36.58%, crude fat: 4.42%, gross energy Kcal/gram. aboratory test of WCH was negative for Eschericia colli and Salmonella shigella, Coliform < 3.0 CFU/g, mold 200 CFU/g. The conclusion of this study is that the waste from closed house (LCH) broiler farms has the potential as a source of protein in alternative feeds for rumonants (chicken and pig).

Abstract

This research was conducted with the aim of knowing the effect of using protein concentrate based on broiler farm waste (KPLA) in rations on weight loss and digestive organ weight. The research used a completely randomi- zed design (CRD) with three treatments and four replications. The treatment is, A: with the use of 0% KPLA, B: with the use of 12% KPLA and C: with the use of 24% KPLA. The research used 12 pigs finisher phase with an average body weight of 66.6 ± 7.74 kg. The research parameters were body weight loss, small intestine weight and length, large intestine weight, and spleen weight. The results of the research were, after fasting for 12 hours, with the use of 0% and 12% KPLA there was a loss of body weight of 2.4% and 1.8% (P>0.05). The use of 24% KPLA (C) can increase body weight loss by 6.2%, significantly higher compared to A. The use of 0% - 12% KPLA does not cause a significant difference in the weight and length of the small intestine (P> 0.05), but with 24% KPLA (C) significan- tly reduced the weight of the small intestine by 11.9% and 11.3% in the length of the small intestine (P<0.05). The use of 0% - 24% KPLA did not affect the weight of the large intestine and the weight of the spleen (P>0.05). The conclusion of this research was the use of KPLA up to 12% did not cause significant changes in the parameters of slaughter weight, weight loss, weight and length of the small intestine. It is recommended to use KPLA in landrace pig rations up to 12%.

Abstract

In livestock production, feed is an important factor that influences the success offarming operations. One effort to improve feed efficiency is by utilizing livestock waste. Thisstudy aimed to determine the effect of poultry waste protein concentrate (KPLA) on the internal offal weight of male Bali ducks. The experimental design used was a CompletelyRandomized Design (CRD) with three treatments and six replications for each treatment (3 ×6), so that each treatment and replication consisted of five male Bali ducks. The treatmentsconsisted of P0 (0% PWPC (control) + 25% CP.144 Red commercial concentrate), P1 (12.5%PWPC + 12.5% CP.144 Red commercial concentrate), and P2 (25% PWPC + 0% CP.144 Redcommercial concentrate). The observed variables were internal offal weights, Liver, heart,gallbladder, lymph, proventriculus, pancreas, gizzard, and intestines. The results showed thattreatment P1 did not show a significant difference (P > 0.05) compared to P0. However,treatment P2 showed a significant difference (P < 0.05) compared to the control treatment. Itcan be concluded that replacing commercial concentrate with poultry waste protein concentrate(KPLA) at a level of 25% is able to maintain the internal offal weights (Liver, heart,gallbladder, lymph, proventriculus, pancreas, gizzard, and intestines.) of male Bali ducks. ABSTRAK Dalam usaha peternakan, pakan merupakan faktor penting yang berpengaruh terhadapkeberhasilan suatu usaha peternakan. Salah satu upayanya adalah dengan memanfaatkanlimbah dari ternak.
