Abstract

This experiment was carried out to study the effect of sucrose level on the physico-chemicalproperties of goat surimi. The muscle tissue of round meat of goat was separated from fat andconnective tissue manually and then was cut into 3 cm size of meat for mincing by using meat mincer.Then, the minced meat was washed three times by using chilling water (5-10oC) which the final washingused chilled 0.5% NaCl solution. The ratio of water to minced meat in washing was 3:1. The final stepwas dewatering by pressing washed minced meat in the screen of linen mesh manually. Finally, rawsurimi was stirred with sucrose 3% (P1), 4% (P2) and 5% (P3) and added sodium tripolyphosphate 0.2%for each treatment. The result showed that both pH and Water Holding Capacity (WHC) increasedsignificantly from P1 (P<0.05), whereas the gel strength was no different. The incline of WHC wasfollowed by the incline of crude protein content. However, sucrose could not affect ash and fat contentas well as salt-soluble protein. Sucrose supplementation at 4% in goat surimi produced the bestcharacteristics of goat surimi.

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.

Abstract

The study was aimed to develop prediction models using stepwise multiple linear regressionanalysis for estimating the body condition score (BCS) from the body weight (BW), testicular length(TL), testicular diameter (TD) and scrotal circumference (SC) of indigenous Yankasa rams. Data wereobtained from 120 randomly selected rams with approximately two and half years of age, from differentextensively managed herds in Nasarawa State, Nigeria. Although pairwise phenotypic correlationsindicated strong association (P<0.01) among the measured variables, there was collinearity problembetween BW and SC as revealed by the variance inflation factors (VIF) and tolerance valves (T). TheVIT was higher than 10 (VIF = 19.45 and 16.65 for BW and SC, respectively). The Twas smaller than0.1 (T = 0.05 and 0.06 in BW and SC, respectively). BW was retained among the collinear variables, andwas singly accounted for 83.7% of the variation in BCS. However, a slight improvement was obtainedfrom the prediction of BCS from BW and TL [coefficient of determination (R2), adjusted R2 and rootmean squares error (RMSE) were 85.3%, 85.1% and 0.305, respectively]. The prediction of the BCS ofYankasa rams from BW and testicular measurements could therefore be a potential tool for sustainableproduction and improvement of small ruminants in Nigeria.

Abstract

In this study the determination of micro mineral elements (selenium, iron and zinc) in meat, spleen and liver of beef were carried out. Brahman cross steers reared under intensive production system in feedlot for 87 days. Samples of meat, spleen and liver were collected from 16 steers aged 24-36 months with four types of feeding treatment, feeding without Se (group I) and feeding with additional supplementary of 0.3 ppm selenium for 25, 50 and 75 days (group II, III and IV, respectively). Samples characterization were carried out by instrumental neutron activation analysis (INAA) using irradiation facility in G.A Siwabessy Serpong reactor. Analysis results showed that there is an increasing of selenium content in meat and liver after 75 days feeding. The mean of selenium in liver for group I, II, III and IV were 0.13, 0.17, 0.20 and 0.31 mg/kg wet weight, respectively, while for liver were 0.43, 0.53, 0.60 and 0.70 mg/kg wet weight, respectively. The mean concentrations for iron in meat, spleen and liver were 11.85, 139, and 38.94 mg/kg, respectively, for zinc were 27.90, 21.70 and 25.27 mg/kg, respectively. In this study, the meat and liver contribute more than 100% of recommended daily allowance (RDA) of Se for children and adults. Spleen have contribution of RDA of Fe 53 to 154%, while the RDA of Zn is contributed mostly from meat by 21 to 56%.

Abstract

Two adult male sheeps fitted with rumen cannula were used in two experiments to study the effects of synchronization of carbohydrate and nitrogen supply in sugarcane bagasse based total mixed ration (TMR) on in situ nutrient degradation. The first experiment was aimed to create three TMR with different synchronization index. Ingredient feedstuffs of TMR were evaluated for its in situ organic matter (OM) and nitrogen (N) degradation kinetics. On the basis of the OM and N degradation kinetics of feedstuffs, three sugarcane bagasse based TMR were formulated with synchronization indexes of 0.37; 0.50; and 0.63; respectively. The TMR had similar levels of crude protein (CP), total digestible nutrients, and neutral detergent fiber (NDF). In the second experiment, the three TMR with different synchronization index were evaluated for in situ degradability characteristics of OM, CP, NDF, and sulfur. The in situ degradation of OM in TMR were decreased (P<0.05) with the increasing of synchronization index. The higher synchronization index in TMR increased (P<0.05) CP degradation of CP. The NDF degradation decreased slightly by the alteration of synchronization index in TMR. The higher synchronization index in TMR reduced (P<0.05) in situ sulfur degradation, and this may not support to effects of synchronization of carbohydrate and nitrogen supply.

Abstract

Staphylococcus aureus (S. aureus) is one among pathogen bacteria that caused mastitis in dairycow in Indonesia. Its ability to initiate infection depends on the surface character of the bacteria. Thesurface character of S. aureus is determined by the corelation of red blood cell hemagglutination activity,hydrophobicity, production of protein A, and bacterial adherence to the mammary epithelial cells of thehost. This research was designed to characterize the surface of S.aureus, which correlates to bacterialadherence. Four isolates of S. aureus were taken from subclinical mastitis milk of dairy farm in Malang,East Java. The surface character of S.aureus was determined by performing the red blood cellhemagglutination test using the dairy cow erythrocyte suspension with concentration of 0.5%, 1%, and2%. The hydrophobicity expression was determined by Salt Aggregation Test (SAT) method using theAmmonium Sulfate suspension with concentration of 1.2 M, 1.6 M, 2.0 M, 2.4M, and 3.2 M. Serum softagar (SSA) test was used to indicate the production of protein A; Ability of adhesion was done byadhering the S.aureus, which were already labelled by Fluorescent Ichtiocyanate (FITC) to themammary epithelial cell of post-calving mice. Result of this this research showed that the surfacecharacters of S.aureus, which correlates to the adherence, comprise of erythrocytes hemagglutinationability, hydrophobicity, and protein A production. Isolates of S.aureus, which is hydrophobic, possesshaemagglutinine, and protein A were able to adhere to mammary epithelial cell with higher quantity

Abstract

The objective of this study was to depict the pig farming performances of three different nativePapuan tribes, i.e. Byak, Onate and Arfak. Sites in Biak were taken from Samofa District. Sites in Yapenwere taken from South Yapen District comprised of Famboaman, Anotaurei, Mariadei and Mantembuvillages. Site in Manokwari was chosen at Sub-district of Wosi. Participatory research using interviewand observation was done towards 105 pig farmers. One-way analysis of variance and Pearson Chisquare(χ2) were used to analyse data. Several indicators tested were age, education, objectives ofrearing pigs, and species of pigs. The characteristics of pig farmers were similar. The variations of pigfarmers’ characteristics ware found in pigs’ rearing experience, animal number and litter size. Offeredfeeding on each physiological period was different. Similar finding were feeding sources and feedingprocess. Reproduction knowledge and their experience in farrowing management are similar amongstthe tribes. In general experiences and knowledge to prevent infectious diseases in general were similar.The three tribes have relatively similar in managing their pig farming systems.

Abstract

An experiment was conduct in order to investigate the effects of feed restriction level and duration and dietary coenzyme Q10 level on growth performance, organ characteristics and plasma lipoproteins. A factorial arangment based on a completely randomized design was performed using two levels of feed restriction (10 and 20% less than the standard Ross strain 308 guidelines), two levels of restriction duration (7 and 14 days) and three levels of coenzyme Q10 (0, 20 and 40 mg/kg feed). The results of the experiment showed that restriction intensity had significant effect on feed intake in first, second and sixth weeks of age (P<0.05), body weight gain in second and sixth weeks of age (P<0.05), and feed conversion ratio in first week of age (P<0.05). Restriction duration had significant effect on feed intake in third week of age (P<0.05), and feed conversion ratio in third and sixth weeks of age (P<0.05). Coenzyme Q level had significant effect on feed intake in first and sixth weeks of age (P<0.05), body weight gain in second, fifth and sixth weeks of age (P<0.05), and feed conversion ratio in second and sixth weeks of age (P<0.05).  In conclusion, considering the positive effects of feed restriction and coenzyme Q10 on broiler yield, the simaltaneous use of feed restriction strategy and dietary coenzyme Q10 can be considered as a management program in order to improvement of broiler productivity.

Abstract

The present study was conducted to evaluate the optimum level of dietary inclusion and the form of feeding sapu-sapu fish (SSF) as a single protein source for feed components of small holder Mojosari duck farming. A total of 180 twenty four wk-old laying ducks were fed with two forms (sun-dried and ground-fresh) and three levels of SSF (10, 20 and 30%) from 24 to 32 wk of age. Experimental diets were formulated containing 105.1; 141.5 and 177.9 g/kg crude protein and 3078; 3065 and 3052 kcal metabolizable energy (ME) /kg diet. Production performance and egg quality were measured. The form of SSF had a significant effect (P<0.0001) on feed intake, egg production, feed conversion, egg mass and egg number except final body weight. No significant effects (P>0.05) were found on all of the performance parameters measured due to feeding levels of SSF except feed intake and final body weight. The interaction of form and feeding level was significant (P<0.05) on egg and body weights. Low performance and egg quality were observed in the birds fed a diet containing the dried SSF. It can be suggested that local ducks required 20% SSF as a single protein source for maximum egg production (41.2%) and total egg number per wk (3.1 eggs/bird/wk) during 8 wk of rearing period. Egg quality can be improved by feeding the fresh SSF. However, due to be sufficiently better processing technique, the dried SSF would be potential to replace the common fish for laying ducks.

Abstract

The aim of this study was to know effects of saline condition to crop physiology, growth andforages yield. A factorial completed random design was used in this study. The first factor was type ofgrass, these were king grass (Pennisetum hybrid), napier grass (Pennisetum purpureum), panicum grass(Panicum maximum), setaria grass (Setaria sphacelata) and star grass (Cynodon plectostachyus). Thesecond factor was salt solution (NaCl) with concentration 0, 100, 200 and 300 mM. Parameters of thisexperiment were the percentage of chlorophyll, rate of photosynthesis, number of tiller, biomass and drymatter yield. Data were analyzed by analysis of variance and followed by Duncan’s multiple range testwhen there were significant effects of the treatment. Panicum grass had the highest chlorophyll content(1.85 mg/g of leaf). Photosynthesis rate of setaria grass was the lowest. The increasing of NaClconcentration up to 300 mM NaCl reduced chlorophyll content, rate of photosynthesis, tiller number,biomass yield and dry matter yield. Responses of leaf area, biomass and dry matter yield to salinitywere linear for king, napier, panicum and setaria grasses. In tar grass, the response of leaf area andbiomass ware linear, but those of dry matter yield was quadratic. The response of tiller number tosalinity was linear for all species.
