Abstract

Cellulose is one of limiting factors in local poultry feed. Yeast exploration of local poultry gastrointestinal tract and its utilization as a probiotic candidate has not been widely studying. A total of 112 isolates of yeast were obtained from the digestive tract of Muscovy Duck, Javanesse Duck and Indonesian Native Chicken in the small intestine, cecum, and colon. Yeast with cellulolytic activity was quantitatively selected using CYG agar + 1% CMC medium with an incubation time of 30 ° C for 48 hours under anaerobic conditions. A total of 107 isolates of yeasts have cellulolytic activity. M41 yeast isolates of Mentok cecum possess highest clear zones cellulolytic activity (0.64 cm). M41 yeast characterization includes molecular identification, growth ability testing in CMC and glucose combination medium, CMCase activity, and viability test of probiotic ability with time variation. The results showed that yeast M41 had 98% proximity with Saccharomyces cerevisiae based on 26S sRNA gene sequence analysis, optimum growth on medium containing 1% CMC and 0.1% glucose (b / v), CMCase activity of 42.98 U / mL, and has a viability of 91.91; 66.22; 42.00; 42.00; 1.83 and 42.13 (%) respectively on bile salts 2 hours and 3 hours, gastric juice 45 minutes and 2 hours, pH 2 and pH 3 for 90 minutes. Based on results of the study, it was concluded that S. cerevisiae M41 potentially as a probiotic candidate for poultry with cellulolytic activity.

Abstract

The pituitary transcription factor (Pit-1) gene is one of the considered genes that responsible to growth in cattle. A specific Pit-1|HinfI gene polymorphism located within exon 6(g.1256G>A) has been shown to be associated with growth and milk traits in cattle. This study aimed to identify the Pit-1|Hinf1 gene polymorphism in Grati-Ongole Grade cattle (Grati-OG cattle). A total of 107 genomic DNA of Grati-OG cattle were used in this study. The detection of polymorphism was performed by PCR-RFLP method. Only AB and BB genotypes were succesfully identified with the frequency of 0.009 and 0.991, respectively. Whereas, the frequency of A and B alleles were 0.005 and 0.995, respectively. The observed genotype frequencies in this population do not deviated from HWE. The value of Ho, He and PIC were 0.009, 0.009 and 0.009, respectively.In conclusion, the Pit-1|HinfI gene polymorphism in Grati-OG cattle is monomorphic and hence it should not be used in further association studies.

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 present study was done to observe effect of agroclimate on milk production and prevalence of sub-clinical mastitis of local Holstein-Friesian dairy cattle in Indonesian small holder dairy farms. The research side were located in Region of <1000 masl and ≥1000 m above sea level (asl) in west Java. Data were obtained from 133 small holder dairy farms included 336 dairy cows in normal lactation period. Parameters observed were agro-climate condition, feed consumption, milk production and milk quality, and sub-clinical mastitis prevalence. Result sowed that THI at <1000 m asl had a range of 76.1-76.7 leads to mild heat stress, while THI at ≥1000 m asl had a range of 66.2 - 66.8 which makes comfort environment to the dairy cow. Differences in feed consumption (P<0.01), milk production and quality (P<0.05) were found among two altitude study location. Milk production at ≥1000 m asl was 2.3 kg higher than at <1000 m asl. The udder health status was also different, a 51% of total sample at <1000 masl was detected sub-clinical mastitis (SCM) as high criteria, while 42% samples that were collected at ≥1000 m asl detected sub-clinical mastitis as middle criteria. In conclusion, agro-climate condition (THI) affect animal’s comfort, milk production and sub-clinical mastitis prevalence.

Abstract

The ADIPOQ and EDG1 genes were responsible in intramuscular fat deposition and marbling scores. This study was aimed to identify polymorphism of indel g.81966364D>I in promoter region of ADIPOQ gene and SNP c.-312A>G in 5' UTR of EDG1 gene in Indonesian beef cattle. Blood samples were collected from 211 cattle, including Bali (44), Madura (20), Pesisir (18), Katingan (20), PO (22), Pasundan (20), SO (12), Brahman (20), Simmental (15) and Limousin (18). Polymorphism of ADIPOQ gene was analyzed using PCR and direct sequencingmethods, whereas EDG1 gene was analyzed using PCR-RFLP (MscI enzyme) and direct sequencingmethods. Results of genotyping indel g.81966364D>I was monomorphic (DD genotype). The SNP c.-312A>G was polymorphic (AA and AG genotype) in Madura, Pesisir, Pasundan, Brahman, and Limousine. The Frequencies of allele A and G were 0.95, 0.92, 0.98, 0.95, 0.94 and 0.05, 0.08, 0.02, 0.05, 0.06 respectively. The values of Ho and He were 0.05-0.17 and 0.05-0.15 respectively and in Hardy-Weinberg equilibrium (P>0.05). In Bali, Katingan, PO, SO and Simmental were monomorphic (GG genotype). In Bali cattle, two novel SNP candidates were found in position of c.-399C>T and c.-273C>G which were potential to be used as genetic markers of marbling score for Bali cattle. As result this study, it can be concluded that ADIPOQ gene was similar while EDG1 gene was different in Indonesian beef cattle. in addition, found two candidates potential SNP in Bali cattle.

Abstract

International trade has been growing rapidly and requires high competitiveness. Broiler industry is one of the sectors that might be threatened by trade liberalization. This study aims to analyze the competitiveness and government policies impact on the broiler competitiveness in actual and free trade condition. This research was conducted in Bogor and Subang using survey method. The sample consisted of 30 local farmers selected by random sampling and an integrated company selected purposively. Further data is analyzed using Policy Analysis Matrix (PAM). Privat Cost Ratio (PCR) and Domestic Resource Cost Ratio (DRCR) analysis showed that small farm has a competitive advantage, but does not have a comparative advantage. While the production by integrated company has comparative and competitive advantages. The policy analysis indicates that overall policies is protective and give benefit to producers. There are three scenarios that are used to portray free trade: reduction in import tariffs, interest rates, and logistics costs. The implementation of free trade will reduce competitiveness in actual price but increase competitiveness in the undistorted market condition.

Abstract

An experiment was conduct in order to investigate the effects of feed restriction level and duration and dietary coenzyme Q10 level on growth performance, organ characteristics and plasma lipoproteins. A factorial arangment based on a completely randomized design was performed using two levels of feed restriction (10 and 20% less than the standard Ross strain 308 guidelines), two levels of restriction duration (7 and 14 days) and three levels of coenzyme Q10 (0, 20 and 40 mg/kg feed). The results of the experiment showed that restriction intensity had significant effect on feed intake in first, second and sixth weeks of age (P<0.05), body weight gain in second and sixth weeks of age (P<0.05), and feed conversion ratio in first week of age (P<0.05). Restriction duration had significant effect on feed intake in third week of age (P<0.05), and feed conversion ratio in third and sixth weeks of age (P<0.05). Coenzyme Q level had significant effect on feed intake in first and sixth weeks of age (P<0.05), body weight gain in second, fifth and sixth weeks of age (P<0.05), and feed conversion ratio in second and sixth weeks of age (P<0.05).  In conclusion, considering the positive effects of feed restriction and coenzyme Q10 on broiler yield, the simaltaneous use of feed restriction strategy and dietary coenzyme Q10 can be considered as a management program in order to improvement of broiler productivity.
