Abstract

This experiment was conducted to determine the role of turmeric powder in lipid metabolism andits influence on the quality of the first quail’s egg. Sixty female quails were assigned into a completelyrandomized design with four treatments (levels of turmeric powder i.e., 0; 13.5; 27; and 54mg/quail/day) and each treatment used 15 quails. The treatment was conducted for 60 days. Parametersmeasured were proximate analysis and the quality of the first layed eggs. At the end of the experiment,serum cholesterol and triglyceride concentrations, abdominal and pectoral fat weights, and feedconsumption were measured. Chemical analysis showed that turmeric powder contained 7.97%curcumin. Supplementation of turmeric powder lowered serum cholesterol and triglycerideconcentrations, egg fat and protein contents, haugh unit and yolk index, but did not affect feed intake,abdominal and pectoral fat weights, egg weight, eggshell weight, eggshell thickness, and egg shellindex. However, quails supplemented with turmeric powder showed a variation in egg laying delayranging from 1 to 16 days. Quails supplemented with 54 mg/d turmeric powder had the highest follicleshierarchy. It was concluded that supplementation of turmeric powder with the level of 54 mg/quail/daydecreased lipid content of the egg and improved the other egg quality parameters.

Abstract

An experiment was conducted to compare the growth curve of rabbit. Three breeds of rabbit,namely Indonesian Local Rabbit (IL), Flamish Giant (FG) and Rex (R) were used in the study.Individual body weights of each breed was measured from birth to 63 days of age with 3-days interval.Those periodical data were separated into different sex, be then it was averaged to analysis growthpattern. Growth curve parameters were estimated to fit growth data. There was no difference in bodyweight between sexs within breed. Indonesian local rabbit had the lowest body weight. The resultsshowed that growth curve paramaters among three breeds were significantly different (P<0.05) for bothsexes. FG had the highest value of asymptotic mature weight, followed by R and IL. In conclusion,Gompertz model was excellent fit for the growth data in rabbit with a high coefficient determination (R2= 0.999).

Abstract

The research was aimed to study the manganese (Mn) status of grazing in Java thin-tailed sheep (JTTS),its interrelation with Mn status in the forages and soil, the influence of seasonal factors and landtopography upon the status of respected mineral. Twenty male JTTS of about 6 months old and 2paddocks with field grass vegetation were used in the research. Treatment factor I was topographynamely plain and slope, while treatment factor II was season, namely dry season and rainy season. Thenumber of experimental sheep was divided into 4 groups with 5 heads of sheep for replication in eachgroup and had been grazed for 2 months. The measured variables were soil pH, Mn content in the soil,forage, feces, and blood plasma. The collected data were processed using analysis of variance withfactorial treatment pattern of 2 X 2 in completely randomized design. Mn level in blood plasma of sheepgrazed on plain and slope paddocks were 0.62 and 0.61 mg/l, respectively, in dry season whereas inrainy season were 0.68 and 0.52 mg/l, respectively. Topography did not influence the level of Mn inblood plasma in dry season. Level of Mn in blood plasma of the sheep was lowest in slope area, whereasin plain area was the highest (P<0.05). Manganese level of soil, forage, feces and blood plasma ofexperimental sheep showed the adequate Mn status.

Abstract

Collagen is the main ingredient in the gelatin manufacture. The purpose of the study was todetermine the pH value, the swelling percentage and collagen yield of chicken shank bones which weresoaked by different HCl concentration and soaking time. The pH value and swelling percentage ofchicken shank bones are indicator that determines amount of collagen yield. The research design usedwas factorial completely randomized design (CRD). Factor A was a concentration of HCl (2%, 3.5% and5%) and factor B was a soaking time (24, 36 and 48 hours) without replication (profile). The resultshows that the the increase of HCl concentration and soaking time affected on the decreasing of pHvalue profile (0.17-0.85), swelling percentage profile (80.25-97.49%) and also collagen yield (1.80-10.02%). The lowest collagen yield of chicken shank bones was suspected caused by the used of Hcl.The highest result of the study was using 2% of HCl concentration for 24 hours. The best result wasfound in the use of 2% HCl and was soaked for 24 hours. Based on those result, the collagen of chickenshank bones was recommended as a main ingredient for gelatin manufacture.

Abstract

Rumen microbes breakdown feed to produce volatile fatty acids (VFA), carbon dioxide, ammoniaand methane (CH4). Metabolic hydrogen in the form of reduced protons is used during CH4 formation aswell as during VFA synthesis. Therefore, VFA concentration in the rumen may stoichiometrically berelated to CH4 emission. The aim of this study was to evaluate methane emission between experimentaland model estimates. Two stoichiometrical models for predicting CH4 from VFA were assessed, i.e.Moss et al. (2000) and Hegarty and Nolan (2007) models. The data sets were obtained from a publishedliterature. Samples used were leaves from 27 tropical plant species. Prediction error was conducted bycomputing root mean square prediction error (RMSPE). Results showed that estimation model of Mosset al. (2000) had lower RMSPE value, i.e. 8.01%, than that of Hegarty and Nolan (2007) model, i.e.10.73%. Variation of methane emission, i.e. the low or high methane can be estimated by VFAcomposition with a sufficient accuracy. Adjusment by considering H2 recovery lowered the biassignificantly. It can be concluded that Moss model had better accuracy in predicting CH4 emission fromVFA composition than that of Hegarty and Nolan model.

Abstract

Optimizing the length of raising time in cattle fattening business should be applied to increasefarmers’ income. A survey research was carried out to analyze the optimum raising duration and itsrelationship with income in the business of Simmental - Ongole Grade crossbred (SOG) beef cattlefattening. This research involved 50 farmers chosen purposively as respondents based on some specificcriteria, i.e. the farmers had been experienced at least for 5 years, the business scale was 1 – 3 bulls andthe cattle’s live weight was around 250 – 350 kg. Data were taken by cross section and time series for 3months, covering respondents’ identity, cattle business condition, business inputs, cattle’s weight, inputand output prices. The data were analyzed using combined data regression model. The optimum raisingduration was calculated using profit function per time, while the inputs were converted into timefunction. All of the costs and incomes of business were calculated. The results showed that the optimumraising duration of SOG beef cattle fattening was reached at the 1.5 months from the cattle aging 16.67months old. The amount of the total cost, revenue and income in the optimum raising duration were IDR7,161,740.00; IDR 7,797,100.00 and IDR 635,350.00, respectively. The amount of the cost, revenue andincome in the optimum raising duration per kg of cattle live weight, were IDR 23,247.00; IDR25,157.00 and IDR 1,910.00, respectively.

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.
