Abstract

The aims of study were to evaluate the use of fermented of oil palm fronds (FOPF) on body weightgain and meat quality of goat. This experiment was arranged in Completely Randomized Design with 3treatments i.e. R1 (grass 0%: FOPF 100%), R2 (grass 50%: FOPF 50%) and R3 (grass 100%: FOPF 0%)and 5 replications. The parameters of the study were feed intake, average daily gain (ADG), weight andpercentage of carcass and meat quality. The results indicated that feed intake and meat quality of goatwas not affected by treatment, but the average daily gain, carcass weight, and percentage of carcass, wasaffected by the differences of percentage of FOPF in the pellet complete feed. The best ration was in theR1 ration (grass 0%: FOPF 100%) that significantly different (P<0.05) from the other rations. The feedintake tended to be higher in goat fed R1 (895.87 g/d) compared to those in goat with the R2 (854.38g/d) and R3 (851.53 g/d). The average daily gain and carcass weight were higher in goat fed R1 rationcompared to those in goat fed R2 and R3. Consequently, the carcass percentage in R1 was higher thanthose in R2 and R3. The carcass percentage was ranged from 38.41-41.38%. The Ribeye area was higherin goat fed R1 (9.73 cm2) than R2 (8.34 cm2) and R3 (7.76 cm2). In this study, the protein content ofgoat meat was ranged from 19.06 to 20.71%, lipid content was ranged from 0.703 to 1.106% and watercontent was range from 72.45% to 74.12%, in which were not different among the treatments. It can beconcluded that the use of FOPF in a complete feed could improve performance and meat quality of goat.

Abstract

The present study aimed to investigate the effect of feeding fermented mixture of cassava pulp and M. oleifera leaf meal (FCPMO) on the breast meat characteristics of broiler chickens. From day 8 onward, 400 Lohmann broiler chicks were allotted to four dietary groups included CONT (maize-soybean-based feed with no additive), BACI (maize-soybean-based feed supplemented with 0.1% zinc bacitracin), FERM (feed containing 20% of FCPMO) and FERB (feed containing 20% of FCPMO and 0.1% probiotic Bacillus subtilis). At day 35, one male chick from each replicate (10 chicks per treatment group) was taken and slaughtered. After being eviscerated and de-feathered, sample of breast meat was obtained for the assessment of meat characteristics. Results showed that feeding FCPMO had no effect (P>0.05) on pH and water holding capacity (WHC) of breast meats. Compared to other groups, FERB meat had higher (P<0.05) cooking loss. FERM and FERB meats had lower (P<0.05) moisture content than that of CONT and BACI meats. Feeding FCPMO with or without B. subtilis increased (P<0.05) crude protein content of breast meats. Feeding FCPMO resulted in lower (P<0.05) fat content in the breast meat. Compared to other meats, breast meats from BACI had higher (P<0.05) ash content. Cholesterol was lower (P=0.08) in FERB than in BACI and FERM meats. The 2,2-diphenylpicrylhydrazyl (DPPH) IC50 values were higher (P<0.05) in meat of CONT than that in other groups. Feeding FCPMO resulted in higher (P<0.05) polyunsaturated fatty acids (PUFA), lower (P<0.05) monounsaturated fatty acids (MUFA) and had no effect on saturated fatty acids (SFA) contents of broiler breast meats. In conclusion, feeding FCPMO produced healthy broiler meat as reflected by the higher contents of protein, PUFA and antioxidants, and lower fat in meats.

Abstract

The aim of this study was to evaluate non-genetic factors and genetic parameters of the growth traits in Sumba Ongole (SO) cattle. The growth traits were consisted of birth weight (BW), weaning weight (WW), yearling weight (YW), average daily gain of pre-weaning (ADG1) and post-weaning (ADG2). Data from 143 heads of SO cattle (year 2011 to 2016) which raised at PT KAR were used in this study. Generalized Linear Model (GLM) analysis was performed to evaluate non-genetic effect including sex, year of birth, generation and season. Therefore, to evaluate genetic parameters, the heritability (h2) and genetic correlation (rg ) were performed using Paternal Halfshib Correlation method. The results showed that sex of calf had no significant effect (P>0.05) on BW, WW and YW, but year of birth had significant effect on those traits. The factor of season had significant effect on WW. The estimation of h2 values of growth traits were included high category (h2>0.30) and accurate (h2>SE) on BW (0.66±0.42), WW (0.65±0.44), YW (0.67±0.42), ADG1 (0.68±0.45) and ADG2 (0.70±0.43). The estimation of rg values were included high category (rg>0.50) and accurate (rg>SE) on BW-WW (0.87±0.63); BW-YW (0.95±0.87); ADG1-WW (0.99±0.34); WW-YW (0.98±0.48) and ADG1-YW (0.95±0.51). It was concluded that trait of WW could be used as selection criteria to increase YW trait in SO cattle.

Abstract

The aims of this study was to compare Tris egg yolk and Citrate egg yolk extender andsupplementation of fructose on citrate egg yolk on the quality of Friesian Holstein (FH) bull semenstored at 5 oC. Semen was collected from 5 FH bulls using an artificial vagina. The semen wereevaluated macroscopic and microscopically. The semen divided into three tubes and extended with Trisegg yolk (TEY), Citrate egg yolk (CEY) or Citrate fructose egg yolk (CFEY). Extended semen wasstored at 5 oC and evaluate daily for sperm motility and viability. There was no significant differences(P>0.05) on the sperm viability among three extender, for every time observation during 144 hours ofstorage. This similar finding found on the sperm motility in all extender for 48 hours of storage. Thesperm motility in TEY demonstrated significantly greater (P<0.05) than in CFEY and CEY extender at72 to 120 hours storage. In the end of storage, sperm motility in TEY (35.2 ± 4.1%) and CFEY (33.5 ±2.71%) extender statistically indicated no significant different, and both were greater than CEY. Inconclusion, CFEY support the sperm motility as good as TEY of FH bull.

Abstract

Central Java is the region that produces the second largest duck egg production in Indonesia or reaches 13.55% of the total national duck egg production. Therefore, duck farming in Central Java requires an economic evaluation to identify the success of the business. The economic analysis in the duck farm industry will update the latest statistics on production costs, outputs and profitability. This study aims to assess the analysis of laying duck business, which includes: marginal production costs, total net income and input-output ratio of duck egg production in various regions in Central Java, Indonesia. The study was conducted using a survey method using multi-stage sampling involving 120 duck farmers from the regency of Tegal, Brebes, and Pemalang. Each district was taken 40 farms as respondents by purposive random sampling with criteria for the number of breeders who had a minimum duck population of 100 ducks and a production period of 8-12 months. The analytical tools used include descriptive statistics and farm budgetary analysis. This study showed that duck breeders incur large costs to obtain production inputs, especially from feed aspects. Although three regencies reported profit based on the estimated input-output ratios, it is only a marginal profit that amounted to1: 1.382, 1:1.658, and 1:1.433 in Tegal, Brebes, and Pemalang, respectively. The conclusion of the study is the performance of duck farms in Central Java are still profitable even in the smallholder duck farm industry, with the highest profits obtained by farmers in Brebes Regency.

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 aim of this study was to analyze the mineral composition of milk, the amino acid composition of milk protein, and the productivity per 305 days of lactation in crossbred cows compared to pure-breed local Ukrainian analogues. The research was conducted at cows of the Ukrainian Black-Spotted (UBS) dairy breed and crossbred cows of the first-generation obtained as a result of crossing with Brown Swiss breed and at cows of the Ukrainian Red-Spotted (URS) dairy breed and crossbred cows of the first-generation obtained by crossing of the URS dairy breed with Montbeliarde breed. In both farms there were two groups of pure-breed and crossbred cows-analogues. The mineral composition of milk and its technological properties in crossbred cows were higher compared to the pure-breed analogues. The fat content of milk crossbred cows exceeded by 0.08-0.16%, protein exceeded by 0.15-0.22%, and the main trace elements include Ca and P – by 2.66-8.83 and 2.12-7.81 mg/100 g of milk, respectively. Milk protein of crossbred cows was marked by a more balanced composition of essential amino acids (EAAs) and their ratio suitable for processing. The amount of EAAs in 100 g of milk protein of crossbred cows was 3.11-6.25% higher compared to local analogues. Crossbred cows dominated pure-breed analogues by the mineral composition of milk. The authors recommend the use of Montbeliarde or Brown Swiss breeds in commercial herds to improve the technological properties of milk.
