Abstract

This research aimed to study the effect of different forage composition in diet on nitrogen balance andmicrobial population of Bali cattle. Randomized Block Design consisted of four feed treatments with 3block of weight live as replicates were used in this study. Body weight of male bali cattle used rangedbetween 181-265 kg. These four treatments based on dry matter were: A (45% elephant grass + 0% ricestraw + 15% glyricidia + 10% calliandra + 30% concentrate); B (30% elephant grass +10% rice straw + 20%glyricidia + 10% calliandra+ 30% concentrate) ; C (15% elephant grass +20% rice straw + 25% glyricidia+10% calliandra + 30% concentrate) and D (0%elephant grass + 30% rice straw + 30% glyricidia + 10%calliandra+ 30% concentrate) . Variables measured were nitrogen balance and rumen microbial population.The collected data were analyzed by analysis of variance. The result showed that nitrogen intake in cattlefed with diet C was significantly (P<0.05) higher than these in other treatments and nitrogen retention(P<0.05) was significantly higher as compared to those fed with diet A. Amylolytic and cellulolytic bacterialpopulations were not significantly different (P>0.05) among all treatments, but the population of proteolyticbacteria was found the lowest (P<0.05) in cattle fed with diet A. It can be concluded that increasedglyricidia and rice straw in the diet could increased nitrogen intake, nitrogen retention and proteolyticbacterial population.

Abstract

Mycotoxins are toxic metabolites produced by some fungal species commonly found in food and feed,particularly in cereals. In intensive production systems, dairy cattle are commonly fed with cereal-richdiets and, consequently, are more exposed to micotoxins. Besides, such diet is often associated with ahigher risk of rumen acidosis which can also affect the performance and the helath of animal. In addition,the efficacy of microbial detoxification can be reduced during acidosis. For instance, some authors observeda decrease in the number of protozoa that are responsible for the degradation of some mycotoxins. Anotherconsequence of acidosis is the potential modification of ruminal absorption of mycotoxins, which until nowhas received scarce attention. Yeast Saccharomyces cerevisiae, probiotic additives have been shown toreduce the post-feeding drop in rumen pH and to increase the number of ruminal protozoa. This effect canbe positive in reducing the absorption and toxicity of mycotoxins in ruminantia.

Abstract

Research aim to derive an excellent hybrid to be positioned as meat-type chicken. An excellent breed which possess uniform morphological character was archived by genetic selection through back-crossed mating shceme in focus on growth rate and plumage color uniformity. Day Old Chicken (DOC) resulted from parent stock broiler cobb 500 and Pelung chicken originated from Cianjur district, West java mating were intensively reared for seven week from hatch. Each chicken weighted every seven day and morphological character assessed at seven weeks old. Observe variable are heterocyst, coefficient Inbreeding (Fx), Inbreeding rate (F), plumage and shank characteristic proportion, and its frequency gene alteration through selection. After serial genetic selection, the BC2 chicken has 1129 g body weight and uniform morphological character. Overall body weight of BC3 chicken offspring from BC2 and F1 was deteriorated compared its broiler predecessor because of Inbreeding depression (Fx: 0.4375; F: 0.3125) and heterocyst decrement (H: -39.33) however, morphological appearance were highly resemble pelung chicken. Based on these finding, BC2 chicken was promised meat-type hybrid chicken which has fast growth rate and similar morphological character.

Abstract

The aim of this study was to compare the quality of Bali bull fresh semen in productive group (below 10 years old) with over productive group and to evaluate the frozen semen quality of bali bull after cryopreservation in Tris egg yolk extender using Dimethyl formamide (DMF) and glycerol in three different concentrations (5%, 6%, and 7%). Semen was collected using artificial vagina. Semen then evaluated macro and microscopically. Macroscopic evaluation conducted visually and microscopic evaluation with the aid of Computer Assisted Sperm Analysis CASA. Immediatelly after evaluation, semen were divided into six aliquots and diluted with Tris egg yolk (TEY) glycerol 5% (TEYG5), TEY-glycerol 6% (TEYG6), TEY glycerol 7% (TEYG7), TEY-DMF 5% (TKTD5), TEY-DMF 6% (TEYD6) and TEY-DMF 7% (TKTD7). Results of experiment showed that there was no difference (P>0.05) among the all parameters, except for semen volume. Semen volume of productive group was higher than over productive age group. No difference was found in post thawing motility of the spermatozoa in TEY extender with 5% glycerol, and TEY with 5%, 6% and 7% DMF. The higher recovery rate of bali bull spermatozoa demonstrated by spermatozoa in TEY extender with glycerol 5% and DMF 6% (63.33±2.40 dan 68.67±2.33). It was concluded that bali bull semen quality did not differ between productive and over productive ages and post thawing semen quality of bali bull in TEY with 5-7% DMF or 5% glycerol was not also different.

Abstract

An immunomodulator is a natural body defence mechanism due to the stimulation of objects/ environments, both specific and non-specific by means of cellular and humoraldefence. The objective of the study was to prove the immunomodulation ability of broiler chickens up to age 35 days that dietary fed various wheat pollard based rations. The design used in the study was a complete randomized design with six treatments and three replications. The treatment of broiler rats consisted of BR-IAJ (T0), control feed with wheat pollard base (T1), control feed with wheat pollard base plus probiotic (T2), wheat pollard based feed steamed (T3), fermented wheat pollard based feed 40% (T4 ) and fermented wheat pollard based feed 60% (T5). The rations used contained 20,5-22,5% protein with 2900-3100 Kcal metabolic energy. Lohman MB 202 Platinum from PT. Japfa Comfeed used in research with average day old chick (DOC) weight of 36,39 + 2,45 g. Parameters observed included body weight, feed intake, feed conversion ratio (FCR), relative weights of liver organ, thymus, lymph and bursa fabricius. The results showed that wheat pollard-based rations had a significant effect (p <0,05) on the relative weight of liver organ, body weight, FCR and ration consumption, but did not affect the relative weights of spleen organ, thymus and bursa fabricius. The mean relative weight of consecutive liver as follows: 2,47 g (T0), 2,83 g (T1), 3,40 g (T2), 2,99 g (T3), 3,15 g (T4) and 3,06 g (T5). The average body weight, consumption and FCR rations were as follows: 1415,24 g; 136,45 g/day; 2,03 (T0), 775,04 g; 125,19 g/day; 3,40 (T1), 813,17 g; 129,86 g / day; 3,36 (T2), 792,89 g; 128,14 g /day; 3,54 (T3), 892,91 g; 138,33 g /day; 3,27 (T4), 969,56 g; 155,52 g/day; 3,37 (T5). The conclusion of the study was that the ration with the addition of wheat pollard 60% was able to provide an increase in body weight gain and the best immunomodulation seen from the aspect of the proportion of immunomodulating organs to the growth of broiler chickens.

Abstract

Classical swine fever (CSF) is a serious and highly infectious viral disease of domestic pigs and wildboar, which is caused by a single stranded RNA pestivirus. A cross sectional study was carried out onsmall-holder pig farmers in West Timor, in the province of East Nusa Tenggara, Indonesia. The objectiveof this study was to describe the management, husbandry and trading practices adopted by pig farmers inWest Timor. A questionnaire survey was administered to the owners of these pigs (n = 240) to gatherinformation from farmers in order to understand management and husbandry practices in the region. Theresults of the questionnaire highlighted the lack of implementation of biosecurity measures by smallholderfarms in West Timor, which has the potential to increase the risk of their pigs to CSF, as well as toother diseases.

Abstract

The aim of this study was to determine the optimal mating time in Etawa Crossbred Goat. This studyused 10 ewes, 2-3 years old, with normal estrous cycle. Initiation of estrous using Controlled Internal DrugRelease Implants (CIDR) intra vaginal and released after 12 days. The development of follicles in theovaries wasobserved using transrectal Ultrasonography (USG) every six hours until reach for 66 hoursafter CIDR removal from the vagina. Clinical signs of standing heat and vulva signs were also observedwhile under USG observation. The follicles were divided into three groups based on their diameter:small(<3 mm), medium (4-4.9 mm) and large (>5 mm) which were observed during theestrous phase. Ovulationwas predicted when large follicles (dominant follicles) havenot been seen anymore. The resulta showedthat the average follicles number in ovary after 36 hours CIDR removal were 0-1 (0.8±0.4 mm) small, 0-1(0.9±0.6 mm) medium and 1-2 (1.7±0.8 mm) large, respectively. The large follicles (7-8 mm) wereseen after36 hours CIDR removal or 24 hours after standing heat. Forty two hours after CIDR removal, the largefollicles werenot being seen anymore. It means, the ovulation were predicted in 36-42 hours after CIDRremoval or 24-30 hours after standing heat. The relationship between follicular development and clinical vulva signs (redness, swelling, mucus) revealed that the highest vulva signs (+++) wereseen in 36-42 hoursafter CIDR removal. It was concluded that the ovulation time occurred in 36-42 hours after CIDR removal,with the high intensity of vulva changes. Therefore the optimal mating time in PE 24-36 hours of standingheat or 36-42 hours after CIDR removal.

Abstract

Brucellosis is zoonotic disease caused by Brucella infections transmitted to human either direct contact with animals or consume their products. This becomes problematic in the world especially in endemic countries of Brucella and development countries. Brucella melitensis is one of pathogenic species from genus Brucella. Combining immunogenic side both the outer membrane protein 31 (OMP31) derived from B. melitensis and superoxide dismutase (SOD) derived from B. abortus has the potential to be developed as a candidate for recombinant vaccine. In this study, the expression protein of fusion OMP31-SOD inserted in pPIC9K plasmid with extra His-tag sequence, intends to be developed as a recombinant protein vaccine. Recombinant plasmids pPIC9K+OMP31-SOD were transformed into Pichia pastoris KM71 using electroporation method. Selection of transformants was as performed using geneticin® concentrations of 0.25 mg/mL – 4 mg/L Selected transformants were grown to express the OMP31-SOD recombinant protein. Protein expression was confirmed using both of dot-blot method and electrophoresis with Coomassie Brilliant Blue (CBB) staining. The OMP31-SOD recombinant protein was successfully expressed extracellular by Pichia pastoris KM71 clones 3, 4, and 6 with a molecular weight approximately 40 KDa.
