Abstract

The duck farmers in Brebes Regency has not been able to deal with the business dynamics with themain problems in feed and Day Old Duck (DOD).The aim of the research was to analyze the businessperformance of duck farmer in Brebes Regency. The technical and economical efficiency was calculatedto find out the status of duck farmer’s business performance. The research was conducted to four mostactive duck farmer groups (KTTI) in Brebes Regency. The research was done based on survey methodwith 123 duck farmers of the group member as the respondents. The research results show that not all ofthe duck farmers performed their business efficiently (the average technical efficiency is 0.9981) sincethe number of duck ownership, forage, and the use of technology were not optimum yet. The return toscale value of the duck farming businesses was 1.0868, which showed the presence of opportunity toincrease production. This research recommends that it is necessary to manage the productionmanagement in order to increase business performance by optimizing the number of duck ownership,forage feed, and the use of technology.

Abstract

The present study was designed to evaluate the effect of Sauropus Androgynus Leaves Extract(SALE) on broiler chickens fed low protein diets. Eighty four mixed broiler chickens (male:female =1:1) aged 20 days were distributed to seven treatment groups as follows: 1) Broilers fed 19% proteinwithout SALE (P0); 2) Broilers fed 19% protein plus 4.5 g SALE/kg (P1); 3) Broilers fed 17% proteinplus 4,5 g SALE/kg (P2); 4) Broilers fed 15% protein plus 4.5 g SALE/kg (P3); 5) Broilers fed 19%protein plus 9 g SALE/kg (P4); 6) Broilers fed 17% protein plus 9 g SALE/kg (P5); 7) Broilers fed15% protein plus 9 g SALE/kg (P6). Experimental results showed that supplementation of Sauropusandrogynus extract to low protein diets had no effect on meat colour, haemorrhages scale in breastmeat, and fatty liver score (P>0.05), but it significantly affected haemorrhages scale in thigh meat(P<0,01), shank colour, meat taste and flavour (P<0.05). In addition, supplementation of the extractsignificantly affected meat fat content (P<0.05) and meat cholesterol content (P<0.01), but it had noeffect on meat protein content (P>0.05). It can be concluded that the leaves extract of Sauropusandrogynus supplementation at level of 9 g/kg diets normalized fat deposition in broiler chickens fedlow protein diets. SALE improved broiler meat qualities.

Abstract

The objective of this study was to evaluate the characteristics of morphometrical measurements inthe female waterfowls. The animals used in this research were 90 ducks , 90 muscovy-ducks and 90mule-ducks in Bulukumba district of Brebes regency, Central Java, Indonesia. Parameters measuredwere maxilla length, neck length, body length, chest circumstance, wing length, chest length, femurlength and tibia length. The data were analyzed using the Statistical Analysis System ver. 9.1. Muscovyduckgenerally had the largest of size, followed by mule-duck and then duck. The most discriminantvariables were showed by chest length and chest circumstance. Muscovy-duck and mule-duck hadclosest genetic distance (3.974870) than both of the distance between duck and mule duck (14.10), andmuscovy-duck and duck (24.73). The smallest errorness level in grouping was showed in duck 1%followed by 2% in mule-duck and 3% in muscovy-duck.

Abstract

This study was designed to determine the physiological response of blood and immune organs ofbroiler chickens fed on various concentration of dietary black cumin powder (BCP) during the dryseason. A total number of 100 unsexed one-day old Cobb broiler chicks were used and distributed to 5treatments (control, antibiotics and without BCP, 20 g/kg BCP, 40 g/kg BCP and 60 g/kg BCP) and 4replications (5 birds for each). Physiological responses of blood and immune organs were measured at30 day of age. Addition of BCP to broiler ration did not significantly effects on physical properties ofblood (leukocytes count, erythrocytes count, haemoglobin, hematocrit, monocytes, and eosinophils) andrelative weights of thymus and bursa of fabricius, but significantly (P<0.05) increased relative weightsof spleen when compared to control. It was concluded that the black cumin grinds (Nigella sativa) as afeed additive could not change the physical properties of blood, relative weights of thymus and bursa offabricius, but it increased the relative weight of spleen at the level of 60 g/kg BCP, which could reduceadverse effects of infectious diseases in broiler chicken.

Abstract

length in North Sulawesi province. Data on animal live weight (LW), body length (BL) and chest girth(CG) were collected from all cows (n=363) kept by traditional household farmers. Regression analysiswas carried out to estimate LW from all linear body measurements. Data were classified based on age ofanimals consisted of five groups with the first age group of two and half years old, to the fifth age groupof seven and half years old. The results showed that age significantly (P<0.05) influenced all bodymeasurements. Correlations between all pairs of measurements were highly significant (P<0.001) for allage groups. Regression analysis showed that live weight could be predicted accurately from chest girthand body length (R2=0.97). Multiple regression model can be recommended to predict live weight ofOngole grade cows based on those variables with their age groups ranging from 2.5 to ≥7.5 years old asfollows: Live weight (kg) = -806.410 + 4.79835 CG (cm) + 2.83500 BL (cm).

Abstract

The study was constructed to observe the effect of rice hull as a fiber sources in the dried hotelfood waste based-diet on fat and cholesterol level of pork. Twenty four heads of two months old ofLandrace x Yorkshire cross barrows were randomly divided into four treatment groups, i.e. without ricehull (R0), 10% rice hull (R1), 20% rice hull (R2), and 30% rice hull (R3). They placed in individualconcrete pen with 1.9 m in length and 0.5 m in width. Feed and water were given as ad libitum.Observation was done for 10 weeks prior to slaughter. Completely Randomized Design was used in thisstudy. Data obtained was analyzev by anova and mean comparison of Duncan's new Multiple RangeTest. Fat content of R0, R1, R2, dan R3 pork were 14.09±0.31, 13.30±0.44, 12.9±20.30 and11.95±0.56%, respectively. Fat content of pork of R0 was higher (P<0.05) than that of others groups.Cholesterol content of pork of R0, R1, R2 and R3 were 256.47±30.23, 252.34±26.56, 217.63±21.93 and199.21±25.94 mg/100 g, respectively. Cholesterol content of pork of R3 were lower (P<0.05) than thoseof R0. It is concluded that the use of rice hull up to 30% in the dried hotel food waste based-diet candecreases fat and cholesterol levels of pork.

Abstract

The objective of this study was to evaluate the response of ovaries in estrus synchronizationprotocol using GnRH-PGF2α based protocol combined progestin in a herd with tie-stall housing system.A total of 20 Holstein Friesian cows at different stages of estrus cycle in a dairy herd were enrolled inthe present study. The cows were randomly allocated into two treatment groups; with and without CIDR(Controlled internal drug release) insertion. All cows received 100 μg of GnRH I.M. at the beginning ofthe treatment (d 0) without regard to the stages of the estrus cycle followed by 25 mg PGF2α IM 7dayslater. Cows in CIDR group were inserted CIDR into the vagina at the time of GnRH administration andwere removed on the day of PGF2α administration. estrus signs were checked twice daily starting onday-2 after initiation of the protocol, except cows in CIDR group the estrus signs were checked startingon day-8 of the protocol. The animals showing estrus signs were noted. Blood samples were collectedfrom all animals on the days of GnRH and PGF2α treatments and on day-10 after initiation of protocolfor progesterone concentration. The results of this study showed that 30% animals in cows withoutCIDR insertion showed estrus signs prior to PGF2α injection. Involving CIDR to synchronized estruswith GnRH-PGF2α based protocol avoided the occurrence of premature estrus and maintained highprogesterone concentration on the day of PGF2α administration. It is concluded that ovarian responseafter involving CIDR in the protocol for estrus synchronization especially using combination of GnRHand PGF2α were much effective to synchronize the initiation of estrus in dairy cows. Likewise, the useof progesterone avoided premature estrus.

Abstract

The study was aimed to predict body composition of local goats fed bagasse based total mixedration (TMR). Fifteen male local goats (18 months old with average body weight of 18 kg ) were used inthis study. Goats were divided randomly into 3 groups, and were fed TMR’s those contained 15, 25, and35% of sugarcane bagasse, respectively. All experimental diets were designed to be isoenergy andisoprotein. After 12 weeks of adaptation to experimental diets and environment, each group wassubjected to feed digestibility trial, body composition, and experiment of feeding effect on serumglucose. The data were analyzed using one way analyses of variance. The results showed that the bodycomposition and serum glucose concentration were not significantly different (P>0.05) amongtreatments. The bagasse portion in the TMR upto 25% lowered daily feed consumption and body weightgain (P<0.05). It was concluded that the use of sugarcane bagasse up to 35% in the TMR did not affectbody composition of goats.

Abstract

An experimental study was carried out to assess the effect of diet quality on productivity and bodycomposition of Kacang goat. Fifteen male Kacang goats weighing 14.28 ± 3.36 kg (CV = 23.55%) weredivided into 5 groups based on body weight. The experimental design used in this study wasRandomized Block Design (RBD) with 3 treatments of dietary protein and total digestible (TDN)contents (T1= diet with 9.20% protein and 54.67% TDN; T2= diet with 11.6% protein and 58.61%TDN; T3= diet with 18.33% protein and 65.23% TDN). Parameters observed were feed intake, drymatter intake, crude protein intake, TDN intake, live weight gain (LWG) and body composition ofKacang goat. The results showed that feed quality did not significantly affect (P>0.05) dry matter intakeand body composition, but significantly affect (P<0.05) protein intake, TDN intake and LWG. It can beconcluded that the higher quality diet resulted in higher productivity, but the higher quality diet was notaffect body composition of Kacang goat, except body fat gain (%).
