Abstract

Growth hormone (GH) is an anabolic hormone which sintesized and secreted by somatrotop cell inpituitary anterior lobe. GH exert its effect on growth and metabolism by interacting with a specificreceptor on the surface of the target cells. Growth hormone receptor (GHR) has been suggested ascandidate gene for traits related to meat production in Bovidae. The objectives of this study were toidentify polymorphism of GH and GHR genes in buffalo. The 452 DNA samples buffalo were collectedfrom five populations in Indonesia (Siborong-Borong-Medan (65), Lebak-Banten (29), Pandeglang-Banten (180), Semarang-Central Java, and Mataram-West Nusa Tenggara (103)). A gene fragment of theGH|AluI gene at 432 bp located on exon 3 and GHR|AluI gene at 298 bp on exon 10 were successfullyamplified by using the techniques of a PCR (polymerase chain reaction) and genotyped by PCR-RFLP(restriction fragment length polymorphism) then -SSCP (single strand conformation polymorphism). Theresults showed no polymorphisms were detected in these genes. All buffaloes tested had LL genotype forlocus GH|AluI and AA genotype for locus GHR|AluI.

Abstract

A 75 days feeding trial was completed to study the effect of inclusion of a combined probioticyeast+herbs in finishing diet on carcass characteristics of beef cattle. Thirty bull of Ongole crossbred,age 2.5-3 years old with average body weight (BW) of 320 kg were used in this experiment. They weredivided into 2 groups, each of 15 animals and were allotted to control and treatment. They wereslaughtered at around 450 kg BW. The treated animals were given a supplementation containingcombined yeast (Saccharomyces cerevisae and Candida utilis) and herbs. All animals were fed a diet ofammoniated rice straw and commercial concentrate with a ratio of 10: 90. Addition of combinedprobiotics + herbs in the diet increased percentage of carcass, dressing and meat, but there were noeffect on live weight gain (LWG), % bone, meat:bone ratio, % body fat, back fat thickness and eyemuscle area. There was a reduction in the percentage of offal due to a decrease in intestinal weight in thetreated animal.

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

This research was aimed to find out the change of tea leaves waste fiber on lipid absorption afterbeing fermented by Aspergillus niger and also to be expected as a model to gain healthy livestockproduct. Tea leaves waste was fermented by Aspergillus niger during 6 day. Fifteen of rats with initialweight of 41.17±4.05 g were fed ad libitum by diets containing different levels of unfermented andfermented tea leaves waste as follows: basal diet (R1), unfermented tea leaves waste 5% (R2),unfermented tea leaves waste 10% (R3), fermented tea leaves waste 5% (R4), fermented tea leaveswaste 10% (R5). The results indicated that bioconversion of tea leaves waste in diet (R4 and R5)decreased almost all of fiber fractions (NDF 75.55%; ADF 57.17%; celluloses 26.74%; lignine 31.19%),except hemicelluloses 18.38%, while the treatment did not change the lipid binding rate (2.07 vs 1.98).Also, the result showed that rats fed with diets containing fermented tea leaves waste (R4 and R5) hadreduced cholesterol (86.25;87.4 mg/dl) and triglyceride (47.06; 46.03 mg/dl), but not on HDLcholesterol(29.28; 26.51 mg/dl). It was concluded that bioconversion property of tea leaves waste byAspergillus niger changed fiber fraction and decreased blood lipid.

Abstract

Some fatty acid supplements in concentrate containing Curcuma xanthorrhiza, ROXB wereevaluated for effects on milk yield, milk fat and protein, including milk fatty acid. Four lactating (4 ± 1.5months ) Fries Holland (FH) cows were allocated into four treatments of concentrate containing 4.5%palm oil (CP0), 4.5% corn oil (CP1), 4.5% roasted ground corn (CP2), and 1.5% corn oil and 3% roastedground corn (CP3), respectively, in 4 x 4 Latin Square experimental design with 3 d-period. Resultsshowed that there were no significant (P>0.05) effects on milk yield, milk fat and protein, and milk fattyacid. However, the highest average of milk production was found in CP2 (8.63 kg/d). Milk fat wasdecreasing to 3.81% in conjunction with the more potential total PUFA (71.81%) in CP3 with corn oiland roasted ground corn. Ratio of omega-6 to omega-3 in milk was the same in both, CP2 and CP3, itwas 2.14. However , since the objective of this research was to improve milk yield as well as milkcomponents and health concern, therefore the CP2 with roasted ground corn was considered as theoptimal one.

Abstract

The purpose of this study was to know productivity and repeatability of local pigeon. Data werecollected from 124 birds that reared under intensive management. The results showed that artificial pairwas 100% and polygamy was 16% (n=62 pair of pigeon). The ration of local pigeon consisting of 50%corn+50% of commercial feed for starter broiler chicken can be applied in field. The average of eggproduction was 1.8 eggs/pair/period, egg weight was 17.7 g, fertility was 96.6%, hatching rate was 77%,embryo mortality rate was 23%, interval period from laying to hatching and suckling was 51 days, 31.4days with hatching, and 17.6 days without hatching and suckling. The day old pigeon weight ranged10.9-16.2 g. Repeatability value of productive traits was high, in which egg weight was 0.64 and day oldpigeon weight was 0.737. Repeatability of reproductive traits was low, that was fertility and hatchabilitywas 0.12 and 0.048, respectively). The squab weight increased from week 0 to 4, then decreased in theweek 5. The growth rate was highest at the week 1, then decreased from the week 2 to 5 with thenegative growth rate occur at the 5th week. The squab growth rate followed a quadratic pattern. It wasconcluded that slaughter squab selection could be done at 4th week old.

Abstract

The experiment was carried out to investigate the effect of feed withholding in the very early life ofbird on its compensatory growth capacity and fat parameters. A total of 60 mixed-sexes of one day oldRoss chicks were used in the experiment conducted with completely randomized design of 2 differentfeeding times after hatching, i.e.: T1: given access to feed and water ad libitum immediately afterhatching until 35d of age; and T2: withheld from feed (fasted) but not from water for 48h after hatchingand then fed ad libitum until d35. The birds were weighed at the start of experiment and weeklythereafter, and DWG was then calculated. Feed intakes and FCR were also recorded weekly. At d36,abdominal fat was taken out from 2 birds per pen and was weighed. Breast meat (skinless) from thesame birds was also sampled for total FA analysis. Final BW (d35) and total feed consumption of earlyfastedbirds were 1935.17±43.90 kg and 2745.55±47.48 kg and those of unfasted birds were2019.00±50.85 kg and 2910.84±128.10 kg, respectively. FCR of early-fasted and unfasted birds at d35were 1.42±0.03 and 1.45±0.07. The magnitude difference of DWG between early-fasted and unfastedbirds was 27% at d7, whereas at d35 the difference was only 4.5%. Abdominal fat percentage to live BWof early-fasted birds was 1.65±0.09% (male) and 1.60±0.10% (female) and that of unfasted birds was2.00±0.19% (male) and 1.89±0.38% (female). Total FA contained in meat of early-fasted and unfastedbirds were 0.82±0.10 and 0.85±0.10 g/100gDM. Overall, BW and feed consumption of early-fastedbirds were significantly lower (P<0.05) than unfasted birds. DWG, FCR, abdominal fat and total FAcontained in meat were not significantly different (P>0.05) between early-fasted and unfasted birds. Inconclusion, holding birds without feed following hatch (under practical conditions) may limit thecompensatory growth capacity of birds in the later age. Fasting applied in the very early life of broilerleads to impairment of cell hyperplasia resulting in permanent stunting. Abdominal fat and total FAcontained in meat might not be affected by fasting for 48h after hatching. The degree or duration of feedwithholding (for 48h after hatching) might not sufficient to reduce adipocyte proliferation or the numberof precursor adipocytes.

Abstract

The purpose of this research was to study the effect of density and floor types on performance,physiological state and immune response of broilers. The research involved 368 male broilers of theNew Lohman strain aged 8 days which were raised up to 35 days at different densities and floor types.Floor types consisted of rice hull litter and bamboo slat were used as the main plot; while densities of 7,10, 13 and 16 birds/m2 applied as the sub-plot. The results showed that the final body weight gain of the35-day Lohmann broilers at densities of 7, 10 and 13 birds/m2 were 28.22, 24.43 and 19.27 kgrespectively, compared to 16 birds/m2 at 13.53 kg (P>0.05). Broilers in the bamboo slats floor hadlymph weight at 3.73 g compared to the litter floor at 2.55 g (P<0.05). Also, broilers in the bambooslats had average RHL (0.65) lower than broilers in the litter floor (0.79). It could be concluded thatbamboo slats best being used for broilers up to a density of 13 broilers/m2.
