Abstract

The study aimed to compare the egg production and hatchability of local ducks under different management systems, namely semi-intensive and extensive. The research conducted was an experimental one-way classification withtwo treatments.Each treatment used 15 male and 120 females (mating ratio 1:8), and ducks aged 13-14 months. Eggs production was recorded during three weeks period. About300 eggs were selected from each treatment to be hatched. Fertility was observedat 4th days of hatching process using egg candler. Data of eggs production, eggs weight, fertility,and hatchability were analyzed using unpaired two sample Student’s t-test. The results showed that average of egg weight, fertility and hatchability were notdifferent under two managementsystem, but egg production in the semi-intensive maintenance was significantly higher (P<0.05) thanthose inthe extensive system.Egg production in the semi-intensivewas 12.3% higher than those in the extensive.In conclusion, the semi-intensive system that is applied in this study the number of eggs production but did not affect the average of egg weight, fertility and hatchability.

Abstract

his study was conducted to analyze the effect of natural curing by various levels of fresh celery leaves (FCL) and various levels of incubation temperature. The incubation temperature was room temperature (RT) and temperature of 40.6oC (40.6) for 2 hours. These incubation temperatures for creating dendeng sapi were designed to provide the similar curing characteristics of the control (by addition of 50 ppm of NaNO2). Four naturally cured dendeng sapi treatments were A1 = 22 g FCL/kg of beef, RT; A2 = 36 g FCL/kg of beef, RT; A3 = 22 g FCL/kg of beef, 40.6; A4 = 36 g FCL/kg of beef, 40.6 and a treatment of conventionally cured dendeng sapi by addition of 50 ppm NaNO2 as a control (A0 ). All of the naturally cured dendeng sapi (A1-A4) showed color, cured pigment, total pigment and residual nitrite which were not significantly different compared with A0 . The FCL used in this study was an effective replacement for sodium nitrite at the test levels in manufacturing natural cured dendeng sapi. These results indicated that at fewer FCL levels (22 g/kg of beef) and a more practical of the incubation for 2 hours at room temperature were more effective to create naturally cured dendeng sapi.

Abstract

An estimation of most probable producing ability (MPPA) value based on the calves performance is very important for the cow selection. The birth data record of 48 Sumba Ongole (SO) cows and record data from 52 callf birth’s performance were used to estimate the value of MPPA. High of r value (r > 0.30) was obtained at the body length (BL). Birth weight (BW), withers high (WH) and chest girth (CG) had a moderate value (0.10 < r < 0.30) of repeatability. The MPPA value of the cumulative calf birth’s performance of cows based on the highest birth records was 4.64 (cow number 3770) and the lowest was -4.64 (cow number 2283). Calf number B2076 (cow number 3586) had the highest ratio of WH (115.70); BL (124.26); CG (118.90), while the highest ratio of BW (168.35) was obtained in calf number B2095 (cow number 3731). It was concluded that the BW of birth had a moderate value of r (0.10) and could be used as a selection criteria accurately.

Abstract

This research was aimed to estimate selection response and accuracy of hatching weight, growth and egg production using different selection intensities in Magelang duck. A nested design was used in this study with experimental material was Magelang duck consisted of 8 male (treatments), 40 female (sub-treatments) and 360 offspring (replicates) and the observed parameter was productive characteristics. Nine DOD from each female were measured for hatching weight and growth up to 8 weeks old. The measured Hen Day Production (HDP) at initial laying for within days. Result showed that different selection intensities (25, 50 and 75%) led to response in 2.968; 1.870 and 0.982 g hatching weight; respectively; 0.00221, 0.00139 and 0.00073 g growth, respectively; and 1.728, 1.088 and 0.571% egg production, respectively. Selection accuracy for hatching weight, growth and egg production was 0.70, 0.76 and 0.51, respectively. Conclusively, the less preserved female proportion, the higher selection intensity value thus the higher selection response. Selection accuracy of production characteristics was based on its heritability value.

Abstract

The objective of this study was to evaluate leaf quality of Gliricidia sepium (Jacq) Steud and vegetative growth under different population density and cutting interval in coconut plantation. Plant material of 30 cm length with diameter of 2-3 cm were planted in the poly-bag of 15 x 25 cm size. The area were fertilized using Triple Super Phosphate (TSP) and Kalium Cloride (KCl) fertilizer at 75 kg/ha during land  plough and using N fertilizer (Urea) at 100 kg/ha applied at two months age of plant. Treatment of population density of Gliricidia sepium (Jacq) Steud at 20, 30 and 40 plants per area of 9 m2 combined with cutting interval of 3; 6; 9 and 12 weeks were conducted in this study. Treatments were set in factorial arrangement based on block randomized design. Variables measured were including quality of leaf, dried matter production rate and vegetative growth. Results showed that nutrient content of the leaf of Gliricidia sepium (Jacq) Steud dictated by cutting interval, and vegetative performance influenced by the interaction of population density and cutting interval. In conclusion, to sustain high dry matter leaf production and quality of Gliricidia sepium (Jacq) Steud underneath coconut plantation management should be focused on the planting and defoliation regimes.

Abstract

The objective of the study was to determine the effects of raw benne seed (RBS, Sesamum indicum) with or without lysine supplementation on the performance characteristics and mineral retention of broiler chickens. The feeding trial lasted for 56 days. One hundred and forty unsexed day old  broiler chicks (Marshall strain) were used for the study. RBS was incorporated into the diets at 15% and 30% levels and  supplemented with  0%, 0.25% and 0.5% of lysine, respectively. Average  weekly feed intake in birds fed the control diet and 15% RBS based diet supplemented with 0.25 % and 0.5% lysine were not significantly different, but significantly (P

Abstract

This research was aimed to determine the impact of balanced energy and protein supplementation with high rumen undegraded protein (HRUP) to milk production and quality in early lactating dairy cows. Twelve early lactating Friesian Holstein cows were divided into two groups (control and HRUP). Both control and HRUP group were fed on a basal diet (forage to concentrate ratio was 60:40; DM basis), with rumen undegraded protein (RUP) levels were 27.47% and 32.78% for control and HRUP, respectively. The experimental diets were given to animals twice daily, morning and afternoon. Water was given by ad libitum. The observed parameters were nutrient intake, quantity and quality of milk production . Data were examined using t-test. Results showed that feed intake, milk production and 4% FCM, milk fat and lactose concentrations, and milk solid non-fat and total solid concentrations were not differed significantly between control and HRUP groups. However, milk protein concentration and production were differed (P
