Abstract

This study was to see physic-organoleptic of butter from goat as compared to cow butter reared in the Mt Merapi, Sleman regency, Yogyakarta. Both butter has been evaluated their fat size and numbers, the value of hardness, melting point, spreading and organoleptic performance. Fat size and numbers have evaluated microscopically, hardness by penetrometer, butter melting point at different temperature 30, 40, and 50 oC, as well as spreading by pressing down with ± 300 gram of weights. Organoleptic performances have been evaluated by panelist. The result of both butter were good. Goat butter contained more number of small-size fat globule lead to softer butter with hardness 0.3 kg/cm2 than cow butter with hardness more than 1.0 kg/cm2. Goat butter have melted faster than cow butter. Cow butter spreading were less rapid with 6 minutes than 1.5 minutes of goat butter. Panelist acceptance of cow butter were bigger than goat butter. It has been concluded that cow butter have had physically hard performance and well accepted than goat butter. Goat butter have presented well as fresh butter than storage butter.

Abstract

Twenty pasundan cows were divided into two treatments int his study aims to determine the correlation between hematological and blood metabolite on the conception rate of Pasundan cows with synchronized estrus and ovulation. Twenty pasundan cows were divided into two treatments 1) estrus synchronization through double injection 5 ml PGF2α , 2)combination of 5 ml PGF2α per cow and 2.5 ml GnRH per cow intramuscularly. The heat of cow is immediately inseminated 2 times with an interval of 6 hours. The observed variables were estrus percentage, conception rate, erythrocyte, leucocyte, hemoglobin, β-hydroxy butyric acid (BHBA), blood urea nitrogen (BUN), and non esterificated acid (NEFA). Data were processed by analysis of variance and correlation- regression. The result showed that PGF2α with GnRH injection resulted in a better conception rate than that of PGF2α (70% vs 60%), the average plasma concentration of erythrocyte, leucocyte, hemoglobin, NEFA, BUN, and BHBA levels respectively was 6.61±0.19 million/µl, 11.30±0.35 thousand/µl, 10.63±0.35 g/dL, 1.65±018 mmol/L, 10.28±1.50 mg/dL, 21.46±1.96 mg/dL. The data obtained were performed variance analysis and correlation regression analysis using SPSS 16.0. The results of the regression analysis showed that the concentration of erythrocytes, leucocytes, hemoglobin, NEFA, BUN, and BHBA had a significant relationship (P<0.05) with pregnancy, and coefficient of determination were 86.4%, 69.1%, 98.3%, -11.7%, -8.2%, -7.0%, respectively. It was concluded that the pregnancy of Pasundan cows has a strong relation between the conception rates with hematological, however blood metabolites showed a weak relation and inversely proportional.

Abstract

The study investigated gut ecology and morphology of the Indonesian indigenous crossbred chickens (IICC) supplemented with the combination of formic acid and Saccharomyces cerevisiae. Two hundreds day-old IICC were distributed to T0 (control diet), T1 (T0 + 0.2% formic acid), T2 (T0 + 0.3% S. cerevisiae), T3 (T0 + 0.2% formic acid and 0.3% S. cerevisiae). Excreta was collected at week 8, while intestinal ecology and morphology were determined at week 9. In duodenum, T3 chicks showed higher and wider (P<0.05) villi. The T2 and T3 chicks showed deeper (P<0.05) crypt than that of T0. The jejunal villi was higher (P<0.05) in T3 than in T0. The T3 chicks had deeper (P<0.05) crypt compared to other groups. In ileum, the villi height was lowest (P<0.05) in T0. The crypt was deeper (P<0.05) in T3 than in other. Crude protein digestibility coefficient was highest (P<0.05), while fecal protein was loswest (P<0.05) in T1 than in other groups. Compared to T0, the treated IICC showed higher (P<0.05) weight gain and feed intake with T3 had the highest gain and intake but gain:feed rasio was the lowest (P>0.05). IIn conclusion, the inclusion of formic acid and S. cerevisiae in diets improved intestinal ecology and morphology. The IICC chickens fed with formic acid and S. cerevisiae exhibited improved growth performance and nutrient digestibility.

Abstract

This study was conducted to evaluate diets containing durian (Durio zibethinus Murr) seed meal (DSM) on the performance, nutrient retention and egg qualities of commercial layers. A total of 120 fifty two -week-old laying hens were distributed according to a completely randomized design in four treatments and five replications with six birds each. The treatments consisted of different levels of durian seed meals (control, 3% DSM, 6% DSM, and 9% DSM). Feeding diets containing durian seed meal had no significant effect (p > 0.05) on the feed consumption of laying hens at 58 wk of age. Inclusion of up to 6% DSM in formulated layer diets did not reduce egg production and nutrient digestibility, but reduced egg weight. No differences (p>0.05) were observed in egg calcium content, egg calcium mass, and yolk color score fed diets containing DSM. This study suggests that DSM could be incorporated up to 6% in laying hen diets without adverse effect on production performance, nutrient retention and egg qualities.

Abstract

The objective of this study was to assess the association of KiSS1 gene polymorphism with reproductive traits in Kaligesing goat. Genotypes of 48 ewes aged three years old were determined using PCR-RFLP and DNA sequencing. Sixteen out of 48 samples were monitored for the estrus cycle and determined their 17β-estradiol and progesterone levels using ELISA method. The results showed that KISS1 gene in the studied population was polymorphic with one single nucleotide polymorphism (SNP T125A). Then SNP was used to analyze genotype all individuals by PCR-RFLP method using MboII enzyme. Three genotypes (TT, TA and AA) were identified. Genotype frequencies of TA were 59.57%, AA were 40.43% while TT was not inculed in calculation for genetic diversity and assosication analysis since the number of genotype only one goat. The allele frequencies of T and A were 29.79% and 70.21%, respectively. The genotype distribution for the SNP was deviated from Hardy-Weinberg equilibrium (χ2=8.10; P<0.025). Hormonal analysis showed that the levels of 17β-estradiol in the follicular and luteal phase were 50.12±61.26 and 42.35±42.43 pg/ml, respectively, while the levels of progesterone hormone in the follicular and luteal phase were 7.87±10.59 and 12.39±15.93 ng/ml. No significant associations of the polymorphism were observed for any hormonal levels. However, it was first report about polymorfism in KiSS1 gene of local Indonesian goat especially Kaligesing goat.
