Abstract

The objectives of this reserarch were to study the effect of semen washing and soybean lecithinlevel on the motility and viability of ram spermatozoa stored at 5⁰C. Semen was collected from threemature rams by artificial vagina. Semen was evaluated by macroscopic and microscopic. Semen wasdivided into ten tubes, the semen of first five tubes was unwashed (W0) and diluted with extender 0%,1%, 2%, 3% and 4% soybean lecithin (L0, L1, L2, L3 and L4). Semen of another five tubes werewashed (W1) then each diluted with similar extender levels. The diluted semen samples were stored at5⁰C and the sperm motility and viability were evaluated each day. The interaction of the semen washingand soybean lecithin levels were no significant differences (P>0.05) but the single factor of soybeanlecithin level was significant differeNces (P<0.05) and the single factor of semen washing were nosignificant differences (P>0.05) on progressive motility and viability of ram sperm.The best extenderwas 3% soybean lecithin (L3) with the percentage of ram sperm progressive motility was 63.18 ± 3.61%and viability was 71.76±2.32%.

Abstract

The research aimed to evaluate dietary vitamin E deposited into the egg of Kedu breeder hen reared in situ and fed an improved diet supplemented with vitamin E. A total of 75 breeder hens and 15 cockerel of Kedu chicken aged ± 12 months, with average body weight of 1667 ± 237 and 2295 ± 250 g/bird, respectively, were distributed into 15 units of semi intensive housing system. A completely randomized designed (CRD) was arranged in the present research with 3 dietary treatments, namely farmer formulated ration (T0), improved ration (T1), and T1 + 6.28 mg/kg vitamin E (T2). Parameters observed were feed consumption, consumption and retention of vitamin E, egg’s vitamin E, egg’s vitamin E deposition efficiency, hen day production (HDP) and egg weight. All data gathered were subjected to analysis of variance and Duncan’s multiple range test to differentiate between treatments. Variables, except feed consumption, HDP and egg weight, were significantly (P<0.05) influenced by dietary treatment. Vitamin E consumption and retention, and deposition increased due to feeding effect of improved diet and supplementation of vitamin E. Dietary vitamin E of farmer’s ration deposited into the egg indicated the highest value (229.23%) followed by improved ration (51.85%), and improved ration + vitamin E was the lowest (5.38%). In conclusion, Kedu hen is likely have a limitation on vitamin E deposited into the egg when the improved ration supplemented with vitamin E is fed, and vitamin E supplementation should be implemented together with the increase of fat content in the ration.

Abstract

The liver of female poultry has a vital role as an organ for biosynthesis of the yolk precursor and has a greater chance of experiencing cellular damages. This experiment was designed to study the uses of curcumin and monochromatic light in suppressing liver destruction during the period of yolk biosynthesis in Magelang ducks. One hundred and ninety two female Magelang ducks were assigned into a completely randomized design with a 4x4 factorial arrangement.  The first factor was dose of curcumin supplementation consisted of 4 levels i.e., 0, 9, 18, and 36 mg.  The second factor was the color of monochromatic light consisted of 4 levels i.e., white, red, green, and blue. The results showed that hydropic and fat degenerations in the livers of Magelang ducks entering laying phase were still in a normal range. There was an interaction effect between curcumin and monochromatic light on the serum SGPT/GOT and liver MDA concentrations (P<0.05). Serum lipid concentrations positively correlated with the increased serum SGPT/GOT and liver MDA concentrations as indicators of liver damages. Supplementation of curcumin and the use of monochromatic light could reduce and suppress liver destruction and damage during laying period.

Abstract

s to assess different CPAs on stallion semen cryopreservation. Skim milk (SM) and Dimitropoulos(DV) were the extenders used in this study; each was added by glycerol (Gly), combination of ethyleneglycol-glycerol (EG+Gly) or dimethilformamide (DMF). Each semen sample was evaluated and dividedequally into six tubes; semen in the three tubes was diluted 1:1 with (SM), while in the remaining tubesthe semen was diluted 1:1 by DV. After being diluted, all tubes were centrifuged at 1006xg for 10minutes. The supernatan discarded, the pellet was rediluted by SM trehalosa or DV trehalose, and addedby G, EG+Gly, or DMF to reach the final sperm concentration of 200x106/ml. The extended semen wasindividually packed in 0.3 ml minitube, equilibrated at 4oC for 2 hours, frozen in liquid nitrogen vaporfor 10 minutes, and then was stored in liquid nitrogen container at -196 oC. After 24 hours, the semenwas thawed at 37 oC for 30 second. There were no significantly different (p>0.05) on the percentages ofmotile and viable sperm in SMT (21.7% and 43.4%, respectively) compared with those extended withDV T extender (26.9% and 50.8%, respectively). DMF demonstrated better results as CPA compared tothe others; and DVTDMF combination had the best protection during cryopreservation in this study.

Abstract

Stearoyl-CoA desaturase (SCD) is an enzyme produced by SCD gene which is responsible for a conversion of saturated fatty acids (SFA) to mono-unsaturated fatty acid (MUFA) in adipose tissue. This enzyme affects the fats in intramuscular so having influence on marbling. The purpose of this study was to obtain the polymorphisms of the SCD gene and their associations with meat quality traits in Bali cattle. The number of samples used were 48 heads of cattle consisted of 24 bulls and 24 cows from BPTU-HMT Bali cattle in the province of Bali. The SCD gene has been amplified using forward primer 5’-ACC CCT TGG TGT GTG GTT GTT CTT C-3 ‘and reverses primer 5'-CCT GAC GAT ACT ATG TTT CTA CTT C-3'. The polymorphisms of the SCD gene were identified by direct sequencing method. Meat quality traits such as thick of longissimus dorsi (TLD), thick of back fat (TBF), thick of fat rump (TFR), thick of rump (TR), marbling score (MS), and the percentage of intramuscular fat (PIMF) were analyzed using the Veterinary Ultrasound Scanner. To determine Hardy-Weinberg equilibrium status, both allele and genotype frequencies were analyzed using GENEPOP program (V3.2). Association of the SCD gene SNP and meat quality traits was analyzed by GLM. This result showed that there were 5 monomorphic SNPs (c.10153A>G, c.10318C>A, c.10329C>T, g.10394G>A, g.10486A>C) and 3 polymorphic SNPs (g.10360G>A, g.10428C>T, g. 10487G>A) were in HW equilibrium. Association analysis showed that g.10428C>T SNP significantly affected marbling score (MS) and percentage of intramuscular fat (PIMF) (P<0.05). Based on these results, g.10428C>T SNP of the SCD gene may be used as a candidate marker to select meat quality traits in Bali cattle.

Abstract

The objective of the study was to evaluate the quality and deposition of isoflavones in the egg due to dietary inclusion of isoflavone soy sauce by-product (ISSBP) in laying hens. Experimental animals were 480 birds of 20-week old laying hens of Isa Brown strain, with initial body weight of 1,754 ± 42 g. The experiment was arranged in a completely randomized design (CRD), with four treatments and six replications (20 birds each). The treatments were dietary inclusion levels of isoflavone soy sauce by-product as follows: ISSBP0 = without isoflavones, ISSBP40 = 40 mg/100g, ISSBP80 = 80 mg/100g, and ISSBP120 = 120 mg/100 g feed. Dietary treatments were given for 10 weeks from week 20 until 30-week old. Parameters observed were egg cholesterol and isoflavone isomers in feed, blood, and eggs. Data of total cholesterol and isoflavone in the egg were statistically analysed and isoflavone isomer concentration in feed, blood, and egg were descriptively described. The results showed that feeding ISSBP significantly (P <0.05) decreased cholesterol and increased isoflavones in egg. Total cholesterol content in egg decreased up to 33.8%. However, isoflavones in the yolk were higher (28.9 mg/g) than those in blood (13.75 mg/g), and those deposited into the yolks indicated better quality because containing more aglicons isomers (87.5%), than those in feed (52%) and blood (68.4%). In conclusion, dietary inclusion of ISSBP to laying hens’s decreased cholesterol content and increased isoflavones deposition into the egg with better quality, so that the eggs can function as functional food.

Abstract

A study was carried out to assess dietary energy utilization in male fat-tailed sheep being fed duringthe day and/or at night. This study were used 12 rams of 12-18 months old with average of initial bodyweight of 27.05±2.9 kg (CV = 10.74%). The experimental design used in this study was a completelyrandomized design (CRD) with 3 treatments and 4 replications. The treatments were feeding during theday (06.00-18.00; DF), feeding at night (18.00-06.00; NF), and feeding all day and night (06.00-06.00;DNF). The diet was offered ad libitum. The results showed that feeding during the day and/or at nightdid not significantly affect (P>0.05) all parameters observed. The average of dry matter intake (DMI),average daily gain (ADG), gross energy intake (GEI), energy digestibility (DE) and energymetabolizability (ME) were 1006 g/d, 75 g/d, 19.2 MJ/d, 74.0% of gross energy, and 66.2% of grossenergy, respectively. The feed efficiency ratio (FCR), gross energy efficiency, digestible energyefficiency, and metabolizable energy efficiency were 7.38%, 3.86 g ADG/MJ, 5.24 g ADG/MJ, and 5.84g ADG/MJ, respectively. It is concluded that time of feeding did not affect the dietary energy utilizationin local rams.
