Abstract

The ex vivo and in vivo studies were undertaken to examine age-effect on the susceptibility of pigsto E. coli F18-diarrhea. The ex vivo experiment was conducted with 2 and 4 weeks old pigs based on theporcine intestinal organ culture (PIOC) model. The in vivo experiment was performed with 2 and 3weeks old pigs fed milk replacer and inoculated with E. coli F18. E. coli F18 inoculation to the intestinalcultures resulted in higher (P<0.01) counts of E. coli associated to the intestinal tissue, but suchdifference was not observed between the 2 and 4 weeks old pigs. Faecal dry matter (DM) decreased(P=0.01), whereas the proportion of pigs with diarrhea and faecal haemolytic E. coli counts increased(P<0.05) following inoculation, however, the difference between the ages was not observed in the invivo study. The interaction (P=0.01) between age and sampling day was observed for the number of totalwhite blood cells (WBC). The proportion of neutrophils decreased (P=0.01), whereas the lymphocytes,red blood cells (RBC), hemoglobin (Hb) and hematocrit (Hct) increased (P<0.01) after inoculation, butthe differences between age groups were not observed regarding these variables. In conclusion, age (2versus 3 or 4 weeks) did not influence the susceptibility of piglet to E. coli F18-diarrhea.

Abstract

This investigation was conducted to study the influence of the pelleted field grass (FG) toperformance of Java thin tail (JTT) sheep. Twelve heads of male JTT sheep were devided into 3 groups,consisted of 4 heads as replication, respectively. There were three kinds of ration as treatments, namely:fresh FG (T0), pelleted FG (T1), and combination between 85% FG and 15% rice bran (T2). Themeasured variables were: feed dry matter (DM) consumption, in vivo dry matter digestibility (IVoDMD)and in vivo organic mattter digestibility (IvoOMD), molar proportion of partial volatile fatty acids(VFAs), and daily body weight gain (DBWG). Data were analyzed by analysis of variance (ANOVA) incompletely randomized design (CRD). Result of this investigation showed hat feed consumption bysheep received pelleted FG was higher (P< 0.05) than those received FG (513 vs 393 g). Ratio of aceticacid : propionic acid in sheep received pelleted FG was lower (P<0.05) than those in sheep received FG(2.53 vs 3.46). Feeding of the pelleted FG resulted in DBWG significantly differed from combinationbetween FG and rice bran (69 and 72 g), and were higher (P<0.05) than feeding of FG (53 g). Inconclusion, the feeding of pelleted FG resulted the higher DM consumption and ruminal propionic acid,the lower acetic acid : propionic acid ratio, than feeding of fresh FG. Feeding of pelleted FG to male JTTsheep increased the DBWG, equivalent to those by feeding of combination between 85% fresh FG an15% rice bran.

Abstract

Objectives of this study were to compare the percentage of Sodium Chloride (NaCl) and cervical mucus profile which includes potential of Hydrogen (pH), abundance of cervical mucus, spinnbarkeit and ferning of dairy cattle at different age during estrus cycle. Thirty Two head of dairy cattle were used as materials which are 2 years old (n = 2), 3 years old (n = 18), 4 years old (n = 8) and 5 years old (n=4). Dairy cattle were estrus synchronized using 50 mg/head of prostaglandin. Data was collected on 48, 72, 78, 84, 90, 120, 144 and 408 hours after prostaglandin administration. The data were analyzed by using non parametric statistic which was Kruskal-Wallis H test. The significant data was tested with Mann-Whitney U test. The result showed that the abundance of cervical mucus was significantly different (P<0.05; χ2 = 0.011) on 84 hours after estrus synchronization. However, level of NaCl, abundance, spinnbarkeit and ferning of cervical mucus was not sigificantly different. In conclusion, the age of dairy cattle did not affected to the condition NaCl percentage, spinnbarkeit, pH and ferning of cervical mucus, but affected to the abundance of cervical mucus on 84 hours after adminitration of prostaglandine.

Abstract

Kejobong goat is known as prolific and high productivity goat breed in Indonesia. PCR-RFLP and sequencing technique was established in the present study to accomplish the polymorphisms of Bone Morphogenetic Protein 15 (BMP15) gene exon 2 on Kejobong goat does. The blood samples was collected from 48 Kejobong does which were selected based on their litter size. The size of PCR amplification of BMP15 gene exon 2 was 837 bp. The product of PCR-RFLP technique digested by HinfI enzyme showed that the samples were monomorphic. Authentication result using nucleotide sequencing found 4 substitution (A391G, C464G, T828C and C830G), 1 alignment gap (site 817) and 1 insertion nucleotide (site 822). This mutations caused 6 haplotypes formatted. The mutants of BMP15 exon 2 on Kejobong goats indicated that this breed had their own mutation controling the prolific trait. The phylogenetic tree build on the sequences of BMP15 gene exon 2 of Kejobong goats was grouped into 3 clusters. The alignment gap indicated to be the specific marker for the prolific trait (duplet) in Kejobong goat. The particular insertion site could be the recognition site of Kejobong goat based on BMP15 exon 2.

Abstract

The present research was aimed to evaluate an interactive effect of cage density and level ofdietary black cumin (BC) on productive efficiency of broiler chickens. A total of 270 broiler chickens(initial body weight of 163.12 ± 8.10g) were allocated into a completely randomized design with a 3 x 3factorial pattern. The first factor was the cage density (bird/m2) namely, D1 = 8; D2 = 10, and D3 = 12.The second factor was BC level (%), namely, B1 = 1; B2 = 2, and B3 = 3. Feed consumption, bodyweight gain (BWG), feed conversion ratio (FCR), protein digestibility, and income over feed cost(IOFC) were the parameters measured. Data were subjected to ANOVA and continued to Duncan test.No interaction between cage density and black cumin on all parameters was observed. Feedconsumption and FCR were increased, but BWG was lowered significantly (P<0.05) due to the cagedensities of 10 and 12 birds/m2 on weeks 2 and 3. Protein digestibility was significantly increased byfeeding 2 and 3% BC. IOFC decreased significantly (P<0.05) when cage densities were 10 and 12birds/m2. In conclusion, the improvement of productive efficiency of broiler chicken reared at the cagedensity of 12 birds /m2 can be sufficiently achieved by feeding 1% black cumin.

Abstract

The aim of this study was to evaluate effect of non genetic factors on reproductive performance ofBali cattle. Data on reproduction performance were collected from Breeding Centre of Bali Cattle inDenpasar-Bali. Reproductive traits studied were age at first calving (AFC), calving interval (CI) andpregnancy rate (PR). To observe the effect of non genetic factors on the reproductive traits, a mixedmodel was used because all of the traits studied were measured repeatedly in individuals. The overallmeans for AFC, CI, PR and preweaning mortality were 43.86±0.70 months, 360.93±4.47 days,88.44±1.91% and 7.58±1.07%, respectively. The results showed that AFC and PR were significantly(P<0.01) influenced by dam year of birth but mating system had no significant (P>0.05) effect. Withregard to CI, dam year of birth and parity affected CI while mating system had no significantly affect(P>0.05) on CI. The preweaning mortality was only affected by the age of dam significantly (P<0.01).The average of reproductive performance and preweaning mortality in Bali Cattle were not dependedremarkably on the mating system being practiced. It might be concluded that an improvement in Balicattle reproductive traits is possible through improving management systems and utilisation ofcontrolled breeding techniques.

Abstract

Beef cattle farmers were interviewed about what “sustainability” means to them with regard to their daily practices, both in their daily working life and after being confronted with the results of an assessment conducted on their farms prior to a focus group discussion (FGD) utilizing the Sustainability Assessment of Food and Agriculture (SAFA) system developed by the Food and Agriculture Organization (FAO) of the United Nations. The study presented in this article was based on two FGDs, using the results of the SAFA online assessment as a tool to initiate and facilitate the discussions. The two group discussions were recorded using a digital voice recorder, transcribed in full and then coded using the software program Transana. The discussions were organized into themes, which allowed a basis for the further analysis. The themes allowed us to build a picture of the participants’ views and thoughts on sustainability with regard to their farming management practices in the light of the SAFA framework, and their own thoughts and perception of the government’s action to promote sustainability, as well as to consider its implications for the futures of their own farms. The interviewed beef cattle farmers thought of sustainability on a day-to-day context rather than as a multi-dimensional concept. In their views, sustainability was very much about being able to continue farming, for the farm to survive and about being able to hand it over to the next generation. However, when presented with the four dimensions of the SAFA framework, they acknowledged the wider perspectives and different aspects of sustainability and reflected about how their own agricultural practices related to these wider aspects too.

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 purpose of this research was to examine the carcass quality and meat quality of native chicken fed dried tomato meal in diet. The study was conducted by using 200 heads of native chickens 10 days. The birds were divided into five experimental diets and each was divided into four replicate groups of ten birds per replicate. The based diet was formulated to contain 42% corn, rice bran 9%, fish meal 10%, fish oil 5%, soybean meal 9% and commercial diets 25%. Tomato meal was included in five experimental diets at levels of 0, 3, 6, 9, 12% to substitute based diets. The treatments were PO = 100% based diet (BD) + 0% tomato meal (TM); P1 = 97% BD+ 3% TM; P2 = 94% BD + 6% TM;P3 = 91% BD + 9% TM; P4 = 88% BD + 12% TM. Chemical composition of tomato meal was: 20.73% crude protein, 1.53% fat, 30.94%crude fiber, 0.98% Ca, 1.20% P and 2,416 kcal/kg of Gross Energy (GE). Results showedthat feeding tomato meal at an inclusion rate of 12% increased slaughter weight, carcass, breast meat, wings, drumstick and thigh, and decreased abdominal fat and blood cholesterol. Moreover, there were no significant difference in giblet (liver, heart and gizzard) between treatments. Meat water and meat crude protein were significantly increased. Meat crude fat and meat cholesterol were significantly decreased. In conclusion, tomato meal can be used as an alternative feedstuff in kampong chicken diets at inclusion levels up to 12% without negative effects on carcass quality and meat quality.

Abstract

Changes of sperm heads morphometric and DNA integrity of freeze-dried bovine spermatozoa were investigated. Freeze-dried spermatozoa had stored in the refrigerator at 4°C for 2 years. Computer-assisted sperm analysis (CASA) was used in this study to identify sperm head morphometry, while for DNA integrity analysis using acridine orange staining. Samples were smeared on glass slides, fixed for 2 h in acetic alcohol and stained with acridine orange solution. After staining, each slide was examined at x400 magnification in a fluorescence microscope with axio vision (Zeiss Company, Germany). Proportion of fluorescence red and green emissions of the sperm head were examined and scored. These results indicated that sperm head had enlarged significantly (P<0.05) after freeze-drying process. However, freeze-dried sperm heads morphometry significantly (P<0.05) decrease after incubation for 3 and 6 hours. Changes of DNA integrity of freeze-dried spermatozoa significantly (P<0.05) decrease after incubation for 6 hours. In the present study concluded that (1) freeze-drying spermatozoa caused sperm head morphometric enlarged, whereas incubation time caused sperm heads decreased, (2) DNA integrity of freeze-dried sperm head is still intact during incubation 3 hours, and decreased DNA integrity occur in incubation for 6 hours.
