Abstract

Study on Indigofera arrecta has not been explored widely yet. Therefore, its growth characteristicand its nutritive value need to be studied. The research was conducted to evaluate growth characteristicand its nutritive value of Indigofera arrecta planted on different planting spaces and different levels ofNPK fertilizer dose. Two factors experiments were assigned in a Split-Plot Design. The first factor (A)was planting space, (1) 50x50 cm and (2) 75x75 cm. The Second factor (B) was level of fertilizer dose,(1) 0 kg P2O5/ha+100kg K2O/ha, (2) 100kg P2O5/ha +100kg K2O kg/ha and (3) 200kg P2O5+100kgK2O/ha. The results showed that planting space had no effect on height of plant (P>0.05) but diameter ofstem were statistically different (P<0.05). In addition, their dry matter yield and crude protein contentwere not different (P>0.05) on either planting space or P fertilizer dose. There were no interactionbetween planting space and P fertilizer dose. In addition, there were no effects either planting space or Pfertilizer dose on dry matter edible part, crude protein content, and plant height. Indigofera arrectaplanted on wider planting space produce bigger stem diameter and bigger number of branch.

Abstract

This study was conducted to determine the effect of various calcium and phosphorus levels on theproduction performance of Bantul Duck. A total of 270 female ducks, 26 weeks age, were used in thestudy with a 3x3 factorial treatment, which is a combination of three levels of Ca: 3.75; 3.25 and 2.75%and three levels of P: 0.45, 0.35 and 0.25%. Each treatment occupied three replication cages, each ofwhich consisted of 10 ducks. The experiment was conducted for 12 weeks.. Data recorded were: (a) feedintake (g/duck/day), (b) egg production (% HDA), and (c) feed conversion. All quantitative dataobtained during the study were analyzed by analysis of variance (ANOVA) using SPSS computerprogram. The results of the variables recorded did not show significantly difference. Increasing Ca levelon feed showed an increasing trend of egg production. The average feed consumption ranged at 151-159g/duck/day; egg production was 75-84%, and the feed conversion was 184-212 g/egg.

Abstract

The aim of the study was to examine the synchronization of estrus and artificial insemination in heifers of Ongole grade and Simental-Ongole grade. The research used 19 Ongole Grade (OG) and 18 Simental-Ongole Crossbred (SOC) heifers. This research applied purposive sampling to determine the research population. The criteria to select the population were heifers which have in mature body. The normality of heifer’s reproductive organs were identified by performing rectal palpation, then 50 mg of medroxy progesterone acetate on vaginal sponge was used to synchronized estrus. The estrus heifer was inseminated using frozen semen. The observed parameters were the number of heifers with normal and abnormal reproductive organs, estrus sign and pregnancy. Data were analyzed descriptively. This study showed that OG and SOC with abnormal reproductive organs was 1 heifer (5.56%) and 7 heifers (36.84%), respectively. The responses of estrus synchronization in heifers with normal and abnormal reproductive organs were 94.17% and 100% in OG, and 100% and 42.86% in SOC. Meanwhile, the pregnancy rate was 70.59 and 0% in OG, and 50.00 and 0% in SOC. In conclusion, the number of SOC heifers with abnormal reproductive organs is higher than OG. Estrus synchronization using 50 mg medroxy progesterone acetate increase the amount of estrus and pregnancy in heifers with normal reproductive organs.

Abstract

This research was aimed to study the influence of animal age and concentration of the acetic acidsolution on physical and chemical properties of pigskin gelatin. The experiment used CompletelyRandomized Design (CRD) with two factors. The first factor was animal age consisted of 3 levels (5, 7and 9 months). The second factor was concentration of acetic acid solution consisted of 3 levels (2, 4and 6 percents). The result showed that animal age had significant effect (P<0.01) on the yields, gelstrength, viscosity, protein content and pH value but interaction of animal age and concentration ofacetic acid had no significant effect (P>0.05) on the yields, gel strength, viscosity, protein content andpH value. It was concluded that pigskin gelatin from ages of 5, 7 and 9 months and acetic acidconcentration of 2, 4 and 6% had similar characteristics to the commercial gelatin, but the optimumproduction of gelatin was combination of pigskin gelatin from 7 months and of 2% acetic acid.

Abstract

This study was embarked upon to predict hatchability and mortality rate of Muscovy ducks in Nasarawa State, Nigeria. Data were obtained from a total of 119 duck farmers. The automatic linear modelling (ALM) and artificial neural network (ANN) models were employed. The average flock size was 9.84±0.60 per household. The predicted hatchability mean values using ALM (8.66) and ANN (8.65) were similar to the observed value (8.66). The predicted mortality mean values using ALM (2.95) and ANN (3.03) were also similar to the observed value of 2.95. Experience in duck rearing, the educational status of farmers, source of foundation stock and season were the variables of importance in the prediction of hatchability using ALM and ANN models. However, primary occupation, source of foundation stock, experience in duck rearing, land holding and management system were the important variables automatically selected for the prediction of mortality. Moderate coefficients of determination (R2 = 0.422 vs 0.376) and adjusted R2 (0.417 vs 0.371) estimates were obtained for hatchability and mortality using ALM. Different patterns were obtained under the ANN models as regards the prediction of hatchability (R2= 0.573 and adjusted R2= 0.569) and mortality (R2= 0.615 and adjusted R2= 0.612). The present information may aid management decisions towards better hatchability and mortality performance in Muscovy ducks.

Abstract

The effect of andaliman fruit juice marination on the amounts of benzo (a) pyrene in charcoal grilled duck meat were investigated in this research. Completely randomized design was used to determine the effect of 4 treatments of andaliman fruit juice concentration (w/v). Twenty four duck meat samples were devided into 4 treatment groups, those were 0% (I), 10% (II), 20% (III) and 30% (IV). Each group consisted of 6 samples. Total Fat, Tio Barbituric Acid (TBA) value and antioxidant activity were measured from all samples. The result showed there was no effect on total fat of duck meat. Antioxidant activity was 18.60 %, 18.06 %, 19.99 % and 7.54 % for andaliman fruit juice of 10%, 20%, 30% and 0%, respectively. TBA value was 1.03 %, 0.89 %, 0.09 % and 0.10 % for treatment II, III, IV and I, respectively. Antioxidant activity of andaliman fruit was decreased the amounts of Benzo (a) pyrene of duckmeat. Charcoal duck meat without andaliman fruit produced 787 ng, it was higher than charcoal duck meat with andaliman fruit (295 ng).

Abstract

The aim of this research was to investigate the influence of body weight and feeding level on the changeof body composition of indigenous ram. This research was expected to establish the efficient feeding levelto produce high growth rate and meat quality of ram in tropical environment. Sixteen rams with differentbody weight (BW) were divided into 2 groups, i.e. light BW (10 + 1.47 kg) and heavy BW (18 + 1.18 kg).The experimental design was Split Plot design with two factors. The main plot was body weight (light andheavy) and the sub plot was level of feeding (FL, 1x maintenance and 1.5 x maintenance). The parametersmeasured in this experiment were live weight gain and body composition. The results of this study showedthat body water, body protein and body fat were significantly higher (P<0.01) in heavy body weight (HBW)than those in light body weight (LBW), and was higher in 1.5xM than those 1xM. Ram of HW and LW hadsimilar change rate of physical composition. Ram given 1.5xM had higher rate of change of body fat andbody water than those given feed at maintenance level. It can be concluded that there was no interactionbetween BW and FL on the change of body water, body protein and body fat. Ram of HBW and LBW hadsimilar rate of change of physical composition. Level of feeding affected body water content, the higherlevel of feeding resulted in fatter ram, leading to less body water content.

Abstract

Beef cattle are meat producers which are beneficial to humans. The purpose of this study was to identify and to control the behavior of beef cattle farmers towards biosecurity in Lamasi District - Luwu Region, South Sulawesi Province. This type of research was descriptive research. The research method was survey to participatory research and the Focus Group Discussion. Total sample was 50 respondents. Data were obtained through interview using questionnaires and observations. Data were analyzed using descriptive statistic. Likert scale 1 until 3 were used to know the response level of disagree and agree about biosecurity. The results showed that beef cattle farmers less agree to biosecurity adoption. Based on subjective norm, farmers’ behaviors agree to adopt biosecurity if they were supported by community leaders and other livestock farmers or farmer groups. Behavior control which becomes the main obstacles to implementing biosecurity are habits, prior implementation and risks. The supporting factors needed time, can be tested on a small scale cattle business, according to the needs of cattle farmers, needed workers, needed knowledge, skills, and information about biosecurity. Beef cattle farmers should be motivated to adopt biosecurity in order to get a healthy beef cattle.
