Abstract

This study was completed to investigate the breed factor that influences milk production in different goat breeds in the tropical environmental area. A total of 28 goats were utilized in this work. These goats consisted of two different breeds, which were Anglo-Nubian and Saanen. Blood samples were withdrawn through jugular veinsof goats into plastic tubes without EDTA for gene polymorphism. A t-test was used to analyse if there are any significant differences in molecular weight and frequency values of DNA between breeds. Investigation of DNA polymorphism in alleles A, B and C of α-casein were identified in all breeds, while allele F were studied in Saanen goats only. As a conclusion; Saanen goats have more varieties α-casein allele

Abstract

The objectives of study were to investigate follicle stimulating hormone (FSH) and luteinizing hormone (LH) level in four groups beef cow composed of Ongole Grade cow delivered twinning calves (OGT), Ongole Grade cow delivered single calf (OGS), Simmental crossbred cow delivered twinning calves (SCT) and Simmental crossbred cow delivered single calf (SCS). Morphometric traits included body weight, heart girth, body length, shoulder height, and abdominal circumference were taken from cows. Cows were reared by farmers in Grobogan and Kendal Regency, Central Java. Blood serums of cows were taken at estrus. FSH and LH concentration were measured with enzyme linked fluorescent assays (ELFA) technique.FSH and LH concentration were compared between OGT, OGS, SCT, and SCS. Result showed that there were no significant difference of FSH and LH concentration between OGT and OGS, between OGT and SCT, between OGT and SCS. There were no significant difference between OGS and SCT, and OGS and SCS. There were no significant difference between SCT and SCS. Low concentration of FSH and LH in all cows was related to suckle period, when prolactin concentration was inversely related to FSH and LH concentration.

Abstract

The objective of this study was to evaluate the effectiveness of phosphate rocks (PRs) fertilizercompared to chemical P fertilizer for the best crop production and macronutrients of alfalfa. Acompletely randomized design under 3x3 factorial patterns was used in this research. The first factorwas different sources of P fertilizer: Guizhou Phosphate Rock (GPR), Jingxiang Phosphate Rock (JPR),and Single Super Phosphate (SSP). The second factor was level of P fertilizer: 75, 100, and 125 mgP2O5/kg soil. A control treatment (without addition of P fertilizer, CK) was added as a comparison withthe treatments. The results showed that JPR was the best for alfalfa production, whereas GPR and SSPwere better for nutrient content in the alfalfa tissue than JPR. On the whole, phosphate rocks had similareffect on alfalfa growth compared to SSP at the experimental conditions.

Abstract

A factorial design was used to analyzethe influenceofSauropus androgynusleaf extract (SALE) and turmeric powder (TP) on fat deposition in broilers fed high-fat diet. The first factor was the source of fat (6% beef fat and 6% palm oil), and the second factor was SALE plus TP [0 g SALE plus 0 g TP (G1), 9 g SALE plus 0.5 g TP (G2), 18 g SALE plus 0.5 g TP (G3), 9 g SALE plus 1 g TP (G4), 18 g SALE plus 1 g TP (G5)]. SALE plus TP affected cholesterol,lauric acid, myristic acid, palmitic acid, stearic acid and eicosapentaenoic acid contents (p<0.01).Fat sources affected fat, cholesterol, lauric acid, myristic acid, palmitic acid, stearic acid and eicosapentaenoic acid (p<0.01). There was a significant interaction between the two factorson fat, cholesterol, lauric acid, palmitic acid, stearic acid, and eicosapentaenoic acid contents. In conclusion, 18 g SALE plus 1 g TP supplementation to high-fat diet resulted in lower stearic acid, but it resulted in higher eicosapentaenoic acid. Supplementation of SALEplus TPto a high-fat diet lowered cholesterol content and changed fatty acidscomposition.

Abstract

Caseins are milk protein subdivided into four main groups which are αS1, αS2, β-casein and kappa-casein (CSN3). Kappa-casein gene influences the manufacturing of milk properties. The aim of this study was to identify the kappa-casein gene polymorphism in Friesian Holstein (FH) cattle. Fifty nine (59) samples consisted of 32 (Malang), 10 (Sukahati Bogor) and 17 (Research Center for Biotechnology-Indonesian Institute of Sciences’s collections)were applied in this study. DNA samples were extracted by high concentrated NaCl and quantified by spectrophotometer. The kappa-casein gene was amplified at 379 bp fragment by PCR method using a pair primer of kappa-casein at 56oC annealing for 30 cycles. PCR-RFLP technique with HindIII was used for genotyping analysis. The result showed that there were three variants of genotypes (AA, AB and BB) in two populations from Malang and RC for Biotechnology-LIPI’s collection while cattle from Sukahati had only AA and AB genotypes. The averages of genotype frequencies were 65.28%; 65.28%; and 3.00% for AA, AB and BB genotypes respectively while frequencies of 0.81 and 0.19 were for A and B alleles, respectively. FH cattle populations were in equilibrium genetics. This finding concludes that polymorphism was found in three of FH populations with A allele was more common in kappa-casein locus. B allele is known having association with milk production, milk component and cheese yield. Increasing of B allele would influence on milk performance of FH cattle. Explorations of quantitative, qualitative and molecular genetics are important to improve dairy cattle performance.

Abstract

Oxytetracycline (OTC) is one of the tetracycline (TCs) broad-spectrum antibiotics widely used inthe chicken industry. However, improper use of OTC with excessive doses potentially leads to residueformation in animal products that can be harmful to consumers in the form of allergic reaction orresistance. This study aimed to detect OTC residues in broiler chicken meat, marketed in traditionalmarkets and supermarkets in Depok, Bekasi, Bandung, Cilegon, Surakarta and Yogyakarta using indirectcompetitive enzyme-linked immunosorbent assay (icELISA) method. The analyses of 67 broiler meatsamples showed only 1 (1.5%) sample was positive for the OTC residue at 86.1 ng/g which meant belowthe maximum residue limits of permissible OTC (100 ng/g). Nevertheless, a stricter regulation for theuse of OTC in the poultry industry and the monitoring of its residue in chicken products prior tomarketing is still necessary to avoid the adverse effects of the residue present in animal products.

Abstract

Transportation over long distances resulted in stress at animal. Under these circumstances, animalusually manifest depression and the impact on physiological condition changes and loss of body weight.The objectives of the research were to examine effect supplementation of organic-Cr type into diets intransport-stress beef cattle on physiological condition, haematochemical (included were haematologicalcondition and blood chemical) and body weight changes. The experiment was conducted using 16 beefcattle those were transported by truck for a distance of 400 km from Malangbong to Tangerang. Theexperiment was arranged by Completely Randomized Design with four treatments and four replications.The dietary treatments consisted of R0 (basal diet without Cr supplemented), R1 (R0+3ppm organic-Crresulted of alkali hydrolysis), R2 (R0+3 ppm organic-Cr resulted from bioprocess), R3 (R0+3 ppmorganic-Cr resulted from bioremediation). The result indicated that type of organic-Cr supplementationat 3 ppm in diet did not influence physiological condition, haematochemical and body weight at beefcattle transported for seven hours. There was indication that beef cattle fed on control diet (without Cr)showed a stress symptom, their loss of body weight were higher (5.41%) compared to beef given dietcontains organic-Cr (3.72%, 5.04% and 4.83%, respectively for R1, R2 and R3).

Abstract

The present study was aimed to investigate the effect of a novel bacteriocin, i.e. lacticin 3147, ongas production kinetics and methane emission under in vitro rumen environment in two consecutiveexperiments. In experiment 1, either no or 10 µM of lacticin was added to hay or hay:concentrate (1:1,w/w) substrate. In experiment 2, the levels of lacticin additions were extended to 0, 10, 25 and 50 µM.Samples were incubated in three replicates in both experiments at 39oC for 24 h. Total gas productionand methane emission were measured during and after the incubation, respectively. Results revealedthat, in general, addition of lacticin had limited significant effects on gas production parameterscompared to control (without lacticin addition). Lacticin addition up to 50 µM did not significantlydecrease CH4 emission, although a tendency of methane reduction existed when lacticin was added at 25µM. Hay diet produced significantly less methane emission than that of hay:concentrate diet both inexperiment 1 and experiment 2 (P<0.05). It can be concluded that lacticin addition up to 50 µM wasunable to decrease CH4 emission in vitro and therefore need to be tested further at higher concentrations.
