Abstract

A research was conducted at Quail Breeding Centre of Padjadjaran University.  A hundred quails of female black and brown color of each line was observed from hatch to age of six weeks. Four growth models were compared: Gompertz, Logistic, Richards, and MMF. The best fit was measured with Coefficient of determination (R2) and standard error of prediction (se). The results showed that all observed models have high accuracy with R2 ranging from 0.9950 to 0.9988 for black color, and 0.9984 to 0.9992 for brown color respectively. Standard errors of prediction (SE) ranged from 1.99 g to 4.01 g for black, and from 1.92 g to 2.52 g for brown, respectively. Gompertz model was more favorable with R2 and SE of 0.9988 and 1.99 g for black, and 0.9991 and 1.92 g for brown, respectively. Age at inflection, maximum average daily gains and weights at inflection were 4.18 week, 27.87 g and 100.23 g for black line and 3.38 week, 25.05 g and 75.34 g for brown line, respectively.

Abstract

Goat milk and roselle (Hibiscus sabdariffa Linn) are food ingredients with health functionalproperties. This research used Lactobacillus acidophilus RRAM-01 and Lactococcus lactis RRAM-01which had been proven as probiotic, and Saccharomyces cereviceae. Saccharomyces cereviseae wasused to produce specific flavor components in koumiss (bacterial fermentation product). The objectiveof this research was to study the characteristics of goat milk probiotic koumiss added that with roselleextract. The results showed that the addition of different concentration of roselle extract (0%, 0.5%, and1%) in the goat milk probiotic koumiss had no effect on chemical and microbiological characteristics ofkoumiss. Goat milk processed into koumiss had ability to suppress the growth of coliform and hadstrong inhibition activity against Escherichia coli ATCC 25922 as tested by agar diffusion test.Microbiological analysis used in this research was the pour plate method. Population of lactic acidbacteria indicated that the product fulfilled standards as probiotics koumiss (1011 cfu/mL), coliform wasnot detected in the products, therefore the products met the criteria of The National Agency of Drug andFood Control (NA-DFC) as probiotic functional food. Sensory evaluation was conducted by usinghedonic quality test. Based on the hedonic quality test, addition of different concentrations of roselleextract increased the intensity of red color and koumiss viscosity, but had no effect to the aroma andsourness of koumiss.

Abstract

Clostridium botulinum neurotoxin (BoNTs) is one of the causes of economic loss in the livestockindustry. This economic loss would be as a direct result when animals poisoned by BoNTs or indirectlywhen the livestock products are contaminated by BoNTs, which end up with the products are banned byauthority. Therefore a routine surveillance of BoNTs in the farm and in livestock product processingindustry is urgently needed. One of the most relatively quick and accurate methods to perform a routinedetection of the presence of BoNTs is enzyme-linkage immunosorbant assay (ELISA). In this article wedescribe the results of the development of ELISA, using polyclonal antibodies against BoNTs-Bproduced locally. Antibodies were generated from six Balb/c mice with standard immunologicalmethods. Mice were immunized three times for a period of 8 weeks with a commercial type BClostridium botulinum toxoid at a dose of 100 ng per mouse per injection. The resulting antibody waspurified by a combination of ammonium sulfate precipitation 50% (w/v) technique and a protein Acolumn method. The results of this preliminary study indicated that the developed ELISA methodcapable of detecting type B Clostridium botulinum toxin up to 1.0 ng/ml.

Abstract

The study was aimed to evaluate the increasing levels of ration energy, with fat-rich unsaturated fatty acids from sunflower oil on the nutrient intake, rumen fermentability and performance of ewes. The experiment used fifteen ewes of 1.5 years old, primiparous, caged individually with their lambs and conducted three treatments and five replications from a completely randomized designed. Those treatments included R1= ration with 0% sunflower oil addition, R2= ration with 4%sunflower oil addition, R3= ration with 6% sunflower oil addition. The variables consisted of dry matter intake, nutrients, ewes performances (birth weight, weaning weight, decreased of body weight), total and partial VFA, the ratio of acetate: propionate, methane production, protozoa and bacterial population. Data were analyzed statistically and descriptively. The results showed that the treatments did not influence dry matter intake and nutrients,. rumen fermentability and ewes performances. Although the treatments increased (P<0.01) fatconsumption and reduced shrinkage of body weight. It can be concluded that the adding sunflower oil as the resource of unsaturated fatty acids up to 6% of the ration was not negatively affected the fermentability of rumen, moreover can improve ewes body condition and, accelerated body weight recovery

Abstract

The objective of the study was to analyze the potential of fourier transform infrared (FTIR) asstress estimation instrument through measurement of catecholamine (CA) and cortisol (CO) levels byinvasive and non-invasive methods. Twelve heads of Ongole grade (PO) cow from slaughterhouse wereused in this study. Twenty four urine samples of pre-slaughter and slaughtering were collected toevaluate the CA and CO levels by ELISA method and Fourier Transform Infrared (FTIR). Data of CAand CO levels were statistically analyzed to determine the difference between pre slaughter andslaughter conditions. FTIR spectra were analyzed using chemo-metrics software. The results showedthat the levels of urinary cortisol were 2.12±1.68 ng/dl of pre-slaughter and 7.58±3.89 ng/dl ofslaughtered and the levels of urinary catecholamine in pre slaughter and slaughter were 3.07±2.05 and4.15±2.68 ng/dl respectively. The results showed a correlation between the FTIR spectra and the resultsof ELISA analysis. FTIR spectrums were distributed in different quadrants, this was caused bydifferences of CA and CO levels between pre-slaughter and slaughtered. It can be concluded that FTIRcan be supposed to analyze the status of stress in animals, especially in cattle.

Abstract

This study was aimed to determine the profiles of pig farming systems. Participatory situationanalysis was employed to gain data relating to pig profiles in the urban and rural areas of Manokwari.Due to the interests of combining many correlated data, multivariate analysis using Principal ComponentAnalysis (PCA) was performed. Cluster Analysis using Agglomerative Hierarchical Clustering wasapplied for analysis of merge samples based on similarity in components’ composition across sites.There were various twelve classes of pig profiles in Manokwari. In principal component of the first axiscorrelation of several components shows strong positive relation e.g. in piglets, sows, and total herd size.Status of region in the first axis of PCA (P1) through which pigs were raised had negative correlation,including grower, household member and pig production. In the second axis (P2), negative correlationswere shown in piglets, grower, boars, total herd size and the Pig Production Potential (PPP). Status ofregion has underpinned profiles of pigs. Several farmers were able to manage their farm continuity in asteady composition. Selling pigs was the main aim and few farmers play a role as pure breeder.

Abstract

The F94L mutation of the MSTN gene (MSTN-F94L) is considered not to cause disrupted the function of the myostatin gene drastically. Interestingly, this mutation has a very significant effect on muscle mass, carcass, or meat yield and meat quality without any associated severe negative problems. This study aimed to confirm the MSTN-F94L mutation in four local cattle breeds in Indonesia. A total of 518 individuals (140 of Bali, 107 of Sumbawa, 168 of Pasundan, and 103 of Holstein-Friesian (H-F) cattle) were used in this study. Genotype identification was performed by PCR-RFLP method. In the present study showed that the wild-type C allele was fixed (1.000) in Bali, Sumbawa, and HF cattle. However, the wild-type C allele and the mutant A allele were found in Pasundan cattle, even though the frequency of the mutant A allele was very low (0.012). Therefore, in conclusion, the mutation of the MSTN-F94L was detected in Pasundan cattle but no in all three cattle breeds. However, the presence of the mutant A allele in Pasundan cattle allegedly derived from Limousin bulls. The further investigation in other local and exotic breeds and its crossing will answer the status of the MSTN-F94L mutation in local cattle breeds in Indonesia.
