Abstract

Stapphylococcus sp., is bacteria that caused subclinical mastitis in Ettawa Grade (EG) goat. Thepurpose of this study was to determine virulance factor Stapphylococcus sp., which was isolated fromsubclinical mastitis EG goat’s milk in Sleman regency, Yogyakarta. A total of 7 isolate Stapphylococcussp., were isolated from subclinical mastitis EG goat’s milk were determinated by several virulancefactors such as haemolysin, clumping factor, and coagulase. Haemolysin was determinated by culture inblood agar plate and incubated in the temperature of 37°C for 24 hours. Clumping factor wasdeterminated by mixing the rabbit plasma with Stapphylococcus sp., in the glass objects. Coagulase wasdeterminated by mixing the rabbit plasma and broth culture of Stapphylococcus sp. After incubated inthe temperature of 37°C for 24 hours in tube, then the gel formation was observed. Haemolytic type ßwas yielded from 5 isolate Stapphylococcus sp., whereas 2 isolates were not haemolytic. Clumpingfactor and coagulase were produced from 2 isolate Stapphylococcus sp. This study showed that not all ofStapphylococcus sp., isolate causing subclinical mastitis in EG goat have virulance factor.

Abstract

The aim of this study was to determine the effect of Anrederacordifolia (Ten.) Steenissupplementation on uterine involution process in rabbit. The research design applied was completelyrandomized design with 4 treatments and 3 replications (T0 = without Anredera cordifoliasupplementation; TI = Anredera cordifolia supplemented two days before parturition; T2 = Anrederacordifolia supplemented two days after parturition; T3 = Anredera cordifolia supplemented two daysbefore until two days after parturition). The results showed that Anredera cordifolia (Ten.) Steenissupplementation could accelerate post partum oestrus in does that were characterized by post partumoestrus behavior, ferning of saliva and cervical mucus. The best treatment was T3, that was four daysAnredera cordifolia supplementation that was administered at 0.45 g/kg of body weight/day. Furtherresearch was needed to find an optimal dose of Anredera cordifolia (Ten.) Steenis on uterine involution.

Abstract

The aims of the research were to confirm the short estrous cycles and determine the blood level ofestradiol 17-β and ovarian follicukar dynamics in these cases. The research was conducted using sevenBali cattle, approximately 2 years of age, kept in healthy condition with normal estrous cycles.Observation of estrus symptoms was performed daily. Ovarian follicles was examined and measuredusing ultrasonography started at the estrus day. Blood samples were collected from jugular vein, bloodsample collection and ultrasonographical examination of the ovaries were performed daily in the sametime. Serum level of estradiol 17-β was performed using EIA. The short cycle estrus were observed in 4Bali cattle (n=7) among natural estrous cycle. They have only one wave ovarian follicular developmentwhereas the maximal size of ovarian follicles ovulation likes the normal cycle The duration of shortestrous cycle was 7-10 days with normal usual estrus behavior. The peak of blood serum level was107.77 ± 55.94 pg/ml when the diameter dominant follicle of short estrous cycle was reached 10.5 ±0.38 mm. It can be concluded that the short estrous cycles may occur in Bali cattle after puberty amongnormal cycles.

Abstract

A research was carried out to analyze the influence of productive factors on the performance ofkarapan (means racing) cattle business in Madura Island, East Java Province, Indonesia. The researchwas conducted by a survey method, with 135 karapan cattle farmers as respondents in regencies ofBangkalan, Sampang, Pamekasan and Sumenep (mainland). The data were collected in the period ofApril to August 2012. Data of zootechnique indicators variables, farmer’s motivation, allocation time oflabour, labour skills, business scale, productivity of karapan cattle, farmers' performance and benefit ofkarapan cattle business were analysed by Lisrel 8.8 program. The results showed that factors ofzootechnique, farmer’s motivation, labour skills and business scale had highly significant influence(P<0.01) on productivity of karapan cattle, but allocation time of labour did not have significantinfluence (P>0.05). The performance of karapan cattle business was highly influenced by productivity ofkarapan cattle (P<0.01). The benefit of karapan cattle business was influenced (P<0.01) by performanceof karapan cattle business. It is concluded that the farmer's benefit of karapan cattle business wasinfluenced by performance of karapan cattle, which in turn was influenced by productivity of thekarapan cattle.

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.

Abstract

This research was aimed to analyze vitamin E and C supplementation in feed on meet quality,thiobarbituric acid reactive substances (TBARS) and myoglobin level of muscovy duck. This researchused 84 Indonesian muscovy duck divided into 7 group of experimental diet, namely E0C0 : basal feedwithout vitamin E and C supplementation, E400 : basal feed with 400 IU of vitamin E supplementation,E600 : basal feed with 600 IU of vitamin E supplementation, C400 : basal feed with 400mg vof itamin Csupplementation, C600 : basal feed with 600mg of vitamin C supplementation, E200C200 : basal with 200 IUof vitamin E and 200mg of vitamin C supplementation, E300C300 : basal feed with 300 IU of vitamin Eand 300mg of vitamin C. A completely randomized design was applied and each treatment had 4replications. The data were analyzed using analysis of variance. Analysis of variance showed thattreatments significantly affect (P>0.01) meat quality, myoglobin level and TBARS level. Vitamin E andC was proven able to improve final pH of muscovy duck meat. Supplementation of 300 IU of vitamin Eand 300mg of vitamin C at feed with 21% of protein and 3100 kcal/kg of energy could improve DIA,cooking loss, flavor, and color of muscovy duck meat; however, the highest meat tenderness wasresulted from 400 IU vitamin E supplementation.

Abstract

Kappa-casein (κ-casein) gene is known as a gene that plays a role in controlling milk protein andalso play a crucial role in the coagulation and curdling of milk. This study was aimed to identifypolymorphisms of the κ-Casein gene of local buffaloes in Indonesia. A total number of 40 heads ofriverine buffalo and 250 heads of swamp buffalo. This study used PCR-RFLP method, whichamplification of the κ-Casein gene resulted an amplicon with length of 157 bp, located in exon 4. Theamplified fragment were digested with EcoRV restriction enzyme, which cut the κ-Casein gene in exon4 at nucleotides of GAT|ATC, revealed the presence of one polymorphism at the base position of 23 bpthat occurs with a substitution of Ile (ATC) of the T genetic variant into Thr (ACC) of the C geneticvariant. Genotyping κ-Casein gene in riverine buffalo produced two types of allele, namely C allele (157bp) and T allele (136 and 21 bp). These two alleles resulted in three types of genotypes, namely CC, CT,and TT. Frequency of the C allele was dominant to T allele. κ-Casein gene in swamp buffalo wasmonomorphic with one allele, namely C allele. Heterozygosity value of riverine and swamp buffaloeswere low. PIC value in riverine and swamp buffalo ranged 0.000-0.288. Fixation index of κ-Casein genein riverine buffalo was low (Siborong-borong SBBC = -0,0036; Deli Serdang = -0.025), but in swampbuffalo was in fixation. This study showed that κ-Casein|EcoRV were polymorphic in riverine buffaloand monomorphic in swamp buffalo.
