Abstract

Indonesia has high genetic resources of local swamp buffalo with good adaptation across regions. However, these animals decline in both population and genetic quality. This research was conducted to study the genetic diversity of Indonesian swamp buffalo. A total of 199 DNA samples (swamp buffalo) from seven provincial populations were used in this study. Genetics identification used three microsatellite markers (CSSM66, ILSTS61, and ILSTS17). Microsatellites were visualized by Polyacrylamide Gel Electrophoresis (PAGE) 10% with silver staining method. Microsatellite data were analyzed using GenAlEx 6.41, Cervus 3.0, and POPTREE2 software. The results showed that a total of 9 alleles were found from the three loci. ILSTS61 had a high PIC (Polymorphism Information Content) compared to the other loci. The high observed heterozygosity of ILSTS61 was found in swamp buffalo from Riau Province, while the Ho value of ILSTS17 ranged from 0.000 to 0.170. This study identified two clusters for Indonesian swamp buffalo, i.e., cluster I (Aceh, North Sumatra, and Riau) and cluster II (Banten, Central Java, West Nusa Tenggara, and South Sulawesi). The two major divergent directions are considered in Indonesia swamp buffaloes across the observed provinces.

Abstract

Zeranol is one of non-steroidal hormonal growth promoters (HGP) that is still permitted to be used in some countries such as Australia, the United States, and others to increase weight gain. However, this non-steroidal HGP is not permitted in Indonesia. The use of zeranol to increase the growth of livestock can cause the occurrence of residue in livestock tissues and organs, having a great dangerous potential for human health. This study aimed to investigate the presence of zeranol residues in 105 samples of bovine meat collected from Jakarta, Surabaya, and Malang cities and analyzed by high-performance liquid chromatography (HPLC). The samples were added with the deproteinizing extractant of 0.2% metaphosphoric acid and acetonitrile (6:4, v/v), and purified using SAX SPE cartridge. Zeranol was then analyzed by HPLC using Shimp-pack VP-ODS (4.6x250 mm) column with a mixture of acetonitrile-water (40:60, v/v) as the mobile phase and detected on photo diode array detector at 262 nm. The recoveries of the method of 3 different concentrations (2, 5, and 10 ng/g) of zeranol were 73.96% to 103.48%. The detection limit and quantification limits were 0.54 ng/g and 1.80 ng/g, respectively. Zeranol residues were detected in 12 (11.43%) out of 105 samples at the concentration of 1.67 to 33.29 ng/g and 7 among them exceeding 2.0 ng/g. The results obtained in this study indicated that zeranol was still being used to increase cattle-meat production. Therefore, strict control must be implemented at all stages, from production to consumption, regarding the application of this HGP in livestock.

Abstract

This study evaluated the effects of steam flaked of corn and barley grains on the reproductive response, ruminal fermentation characteristics, metabolic disorder, and milk production of postpartum Holstein cows. A total of 40 postpartum Holstein dairy cows were divided into 4 groups (n=10) and fed 1) ground grains (control), 2) steam flacked corn+milled barley, 3) steam flacked barely+milled corn, and 4) steam flaked corn and barley. The animals were treated for 0-30, 30-60, 60-90, and 90-120 days post-calving. Milk yield and compositions, total conception rate, endometritis, pyometra, ruminal fermentation characteristics, ketosis, and acidosis were assessed. This study was conducted in a completely randomized design. The results showed that dietary inclusion of steam flaked grains improved milk yield and compositions during the experimental period compared to the control group (p<0.05), except for cows treated for 0-30d days post-calving. Cows fed steam flaked grains showed a lower occurrence of reproduction and metabolic disorders compared to the control group (p<0.01). Cows fed a combination of steam flaked grains showed better pregnancy rates in the first 100 days and open days of postpartum cows compared to cows in control and a single form of steam flaked barley or corn (p<0.05). Total VFA, acetate, propionate, butyrate, and valerate were higher in cows fed steam flaked compared to the control group (p<0.05). Feeding steam flaked grains is advised for improving reproductive performance, milk variables, and rumen fermentation profiles in dairy cows.

Abstract

This study was conducted to determine the effects of the fermentation duration of coconut dregs (CD) by Saccharomyces cerevisiae and the addition of ammonium sulfate on the growth performance, feed digestibility, carcass, and digestive organ developments. A finely ground CD was autoclaved at 20 psi for 20 minutes and added distilled water to meet 80% moisture content. The autoclaved substrate was added with different concentrations of ammonium sulfate and fermented with Saccharomyces cerevisiae to produce Saccharomyces cerevisiae-fermented CD. A total of 192 day-old-unsexed Cobb broiler chicks were used and kept for 6 weeks. The birds were fed experimental diets ad-libitum. The experimental diets were produced by two durations of fermentation (5 days and 7 days) and three levels of ammonium sulfate (0%, 0.2%, and 0.4%) in 4 replicates. The experimental diets were offered ad-libitum and water were available at all times. Fermentation decreased lipid and crude fiber content of CD and the addition of ammonium sulfate increased protein content and amino acid concentration of CD. The bodyweight gain of birds increased when the CD was fermented for 5 days and with the addition of 0.2% ammonium sulfate. Dry matter digestibility and protein digestibility were improved when CD was added with 0.2% ammonium sulfate. In conclusion, fermenting CD for 5 days increased body weight gain and the addition of 0.2% ammonium sulfate improved the feeding value of the diet and growth of birds.

Abstract

The CD1B gene has an important role in the immune system of poultry by mediating antibody induction. The study aimed to identify the CD1B gene polymorphism and its association with the concentration of IgY and ND antibody titers in IPB-D1 chicken. As many as 111 of IPB-D1 chickens at 21 weeks old were used in this study. Polymorphism identification of the CD1B gene was made using the PCR Sequencing method, while the IgY and ND antibody titers were done using the ELISA and HI test, respectively. The associations of gene polymorphism with IgY and ND antibody titers were analyzed using the General Linear Model (GLM) procedure and Duncan`s Multiple Range test. The results show that there are 4 SNPs in exon 3, i.e., c.550 G>A, c.562 T>A, c.588 A>G, and c.612 C>G. All the SNPs are missense, silent mutations, and polymorphic. The c.550 G>A and c.562 T>A SNPs were in Hardy Weinberg’s equilibrium and heterozygosity (0.054-0.252) condition, while the c.588 A>G and c.612 C>G SNPs were not in equilibrium and their heterozygosity was low (0.072-0.252). The combination of 4 SNPs generated 8 haplotypes, i.e., haplotypes 1, 2, 3, 4, 5, 6, 7, and 8. Haplotypes 1, 2, and 8 had high frequencies (17.6%-23.5%). The c.588 A>G and c.612 C>G mutations were significantly associated (p<0.05) with IgY concentration and c.562 T>A were significantly associated (p<0.05) with ND antibody titers. The haplotypes 2 and 8 with a combination of c.588 A>G and c.612 C>G mutations had higher IgY concentration and ND antibody titers (p<0.05) compared to the other haplotypes. In conclusion, this study has identified the CD1B gene as a polymorphic and is associated with IgY concentration and ND antibody titers in IPB-D1 chicken.

Abstract

This experiment was implemented to evaluate the influence of 3 plant extracts involving garlic (GC), cinnamon (CN), and black cumin (BC) powders in broiler chicken diet from 1-42 d on productive, physiological, and immunological traits. In total, 240 birds were assigned into 4 groups, each with 3 replicates. In the control group (CO), the chickens were fed with a balanced diet. Experimental groups were composed by supplementing the diet with 4 mg/kg of diet for each GC, CN, and BC. At 3 and 6 weeks, GC, CN, and BC groups achieved higher body weights, weight gains (p≤0.01), and low feed conversion ratio. GC group recorded low feed intake (p≤0.05) compared to the CO and the other groups from 1 day–6 weeks. GC, CN, and BC groups registered high (p≤0.01) PCV value and lower cholesterol and triglycerides concentrations in serum compared to the CO group. Reduction and increase (p≤0.01) in serum glucose and protein for GC and CN, and CN and BC, respectively, were recorded. High levels of triiodothyronine (T3) (p≤0.05) and thyroid-stimulating hormone (TSH) in GC and CN groups and all treated groups had high concentrations of thyroxine (T4) (p≤0.01) compared to the CO group. Moreover, a clear augmentation in serum antibody titer against Newcastle and Gumboro diseases in GC, CN, and BC compared with the CO group was observed. It was concluded that GC, CN, and BC extracts at the present level may be used to enhance the productive, physiological, and viral immunological characteristics of birds.

Abstract

The objective of this study was to evaluate the effect of feeding cassava leaf meal and golden snail on performances, chemical, and physical qualities of local duck egg. The experiment used 180 Pajajaran laying ducks of 20 weeks of age and was offered dietary treatments up to 26 weeks of age. The experiment was conducted in a completely randomized design with a 3 x 2 factorial arrangement. The first factor was the treatment of cassava leaf meal consisted of 3 levels, i.e., 0%, 5%, and 10%. The second factor was the treatment of golden snail consisted of 2 levels, i.e., 0% and 10%. Each experimental unit used three replicates and each replicate consisted of ten ducks. The results showed that there was no interaction effect of cassava leaf meal and golden snail treatments on laying duck performances and egg qualities. There were significant effects of cassava leaf meal and golden snail treatments (p<0.05) on egg production, feed intake, egg mass, egg index, and egg yolk color. However, egg weight, feed conversion ratio, yolk fat, yolk cholesterol, and yolk TBARS values, albumen weight, eggshell weight, shell thickness, and Haugh unit values were not affected (p>0.05) by treatments of cassava leave meal and golden snail. The utilization of 10% cassava leaf meal in the diet significantly improved egg production, feed intake, egg mass, and yolk color (p<0.05). The lowest egg index was found in the eggs produced by ducks fed diet containing 5% cassava leaf meal, but it is still within the normal range. Ducks fed a diet containing 5% golden snail significantly had higher feed intake, egg mass, percentage of albumen, and yolk color. It was concluded that there was no interaction effect of cassava leaf meal and golden snail treatments on laying duck performances and egg qualities. A diet containing 10% cassava leaf meal or a diet containing 5% golden snail had the greatest effects on the performance and physical quality of egg without affecting the chemical quality of the egg.

Abstract

Bekasam is a fermented food from Indonesia that potentially improves the quality of sausage when incorporated in the ingredients. This research was aimed to study the chemical, microbial, and sensory characteristics of sausage made of various concentrations of beef and bekasam meat. The chemical, microbial and sensory characteristics of sausage were investigated using an experimental method in a completely randomized design with 5 treatments, namely T1 (100% beef); T2 (75% beef + 25% bekasam meat); T3 (50% beef + 50% bekasam meat); T4 (25% beef + 75% bekasam meat); and T5 (100% bekasam meat). Data analysis of chemical and microbial characteristics was subject to ANOVA and post-hoc Duncan test, while sensory characteristics were analyzed using Kruskal-Wallis test and The Mann-Whitney test. The results showed that the addition of bekasam meat into the sausage mixture significantly (p<0.05) decreased fat content and sensory characteristics (color, flavor, texture, and overall acceptability). Meanwhile, it increased total bacteria, E. coli and S. aureus inhibition in the sausage. In conclusion, bekasam meat fermented with L. plantarum showed probiotic potentials and could modify beef sausage production.

Abstract

This study aimed to identify the best green-leaf offerings of Urochloa brizantha cv. Marandu for pasture-finished lambs receiving protein-energy supplementation at the rate of 1.6% of their body weights (BW). The animals were assigned into four treatments, which consisted of varied green-leaf offerings, namely, 105, 90, 75, or 60 g of dry matter/kg of body weight (BW). Sixty-eight contemporary Texel × mixed-breed lambs with an average initial BW of 22.6 kg were used over two years of experiment. The experiment was set up in a completely randomized design, the data were evaluated by analysis of variance and the means were compared by Tukey’s test at the 0.05 significance level. There was no significant effect of year neither interaction of year with green-leaf offer. There were significant effects of leaf offer on dry matter intake (DMI) with behavior of positively linear (p<0.05). There were significant effects of green-leaf offer on final BW and average daily gain, and lambs receiving of 75 g/kg green-leaf offer showed the highest ADG (179 g/d). There were no significant differences in the carcass, meat, and primal cuts between the groups of lambs receiving different herbage offerings. There were significant effects of leaf offer on slaughter weight, hot carcass weight, and subcutaneous fat thickness. Lambs receiving of 75 g/kg leaf offer showed the highest SFT (5.8 mm). Slaughter weight and hot carcass weight averaged 41.52 kg and 20.07 kg, respectively. We recommend the treatment with leaves offer of 75 g/kg BW of Marandu pasture for the finishing of lambs supplemented at 1.6% of BW.
