Abstract

This study was conducted to evaluate diets containing durian (Durio zibethinus Murr) seed meal (DSM) on the performance, nutrient retention and egg qualities of commercial layers. A total of 120 fifty two -week-old laying hens were distributed according to a completely randomized design in four treatments and five replications with six birds each. The treatments consisted of different levels of durian seed meals (control, 3% DSM, 6% DSM, and 9% DSM). Feeding diets containing durian seed meal had no significant effect (p > 0.05) on the feed consumption of laying hens at 58 wk of age. Inclusion of up to 6% DSM in formulated layer diets did not reduce egg production and nutrient digestibility, but reduced egg weight. No differences (p>0.05) were observed in egg calcium content, egg calcium mass, and yolk color score fed diets containing DSM. This study suggests that DSM could be incorporated up to 6% in laying hen diets without adverse effect on production performance, nutrient retention and egg qualities.

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

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

Abstract

An experiment was conducted to investigate the expired bread meal used as corn substitution in thebroiler diets to optimally the product performance. One hundred day old chick (DOC) male broilerswere given the same diet until 2 weeks old, and then given the treatment diet until 7 weeks of age. ACompletely Randomized Design was used in this study. Data were analyzed by variance of analysis, andfollowed by Duncan’s Multiple Range Test The treatments were : T0 = control feed (without expiredbread meal), T1 = corn substituted with 10% expired bread meal, T2 = corn substituted with 20%expired bread meal, T3 = corn substituted with 30% expired bread meal and T4 = corn substituted with40% expired bread meal. The result indicated that corn substituted with expired bread meal up to 40%has not significantly affected on carcass weight, carcass percentage and feed conversion, but decreasedsignificantly on feed consumption and body weight gain. It can be concluded that the use of expiredbread meal 30% of the proportion of corn produced the most optimal broiler performance. Thesubstitution corn with expired bread meal 40% was decreased body weight gain.

Abstract

International trade has been growing rapidly and requires high competitiveness. Broiler industry is one of the sectors that might be threatened by trade liberalization. This study aims to analyze the competitiveness and government policies impact on the broiler competitiveness in actual and free trade condition. This research was conducted in Bogor and Subang using survey method. The sample consisted of 30 local farmers selected by random sampling and an integrated company selected purposively. Further data is analyzed using Policy Analysis Matrix (PAM). Privat Cost Ratio (PCR) and Domestic Resource Cost Ratio (DRCR) analysis showed that small farm has a competitive advantage, but does not have a comparative advantage. While the production by integrated company has comparative and competitive advantages. The policy analysis indicates that overall policies is protective and give benefit to producers. There are three scenarios that are used to portray free trade: reduction in import tariffs, interest rates, and logistics costs. The implementation of free trade will reduce competitiveness in actual price but increase competitiveness in the undistorted market condition.

Abstract

The objectives of present study were to formulate development strategies for dairy goat' farms that capable of supporting goat's milk agribusiness. Three medium scale dairy goat farms located in Bogor Regency which has population of more than 100 heads and has established more than 10 years were purposively selected for the study. Data were collected during February to May 2014. The design of this study was based on descriptive qualitative approach (rapid appraisal approach). Data were analized using internal factors evaluation (IFE) and external factors evaluation (EFE), strategic position and action evaluation (SPACE) matrix, and grand strategy matrix. It was revealed that dairy goat farms in Bogor Regency were located in quadrant I in SPACE matrix, which was on the aggressive strategy. Dairy goat farms have many resource advantages, despite facing various threats. The Grand Strategy Matrix analysis showed that dairy goat farms were in quadrant I. Dairy goat farms were in an excellent position to take advantage of the opportunities, overcome internal weaknesses and avoiding multiple external threats. The best strategies to be selected for dairy goat farms were market penetration and product development.

Abstract

nin level in fermentation medium (0, 0.1, 0.2, or 0.3 mg/ml), and many kinds of feed (king grass,rice bran, and king grass:rice bran, 60:40 w/w) on protozoa numbers, ammonia concentration, microbialprotein, pH and cellullase activity. Each treatment was consisted of three replicates. Fermentation wasdone in syringe and used in vitro gas production medium. The data obtained were analyzed by varianceanalysis using factorial design (4x3). The differences between mean values were analyzed by Duncan’snew multiple range test (DMRT). The result showed that protozoa numbers decreased 17.22, 42.73 and49.57% (P<0.01) for 0.1, 0.2, and 0.3 mg/ml saponin, respectively from 8.19×103/ml in the control. Theaddition of 0.1 mg/l saponin increased ammonia concentration from 33.04 mg/100 ml (without saponin)to 37.12 mg/100 ml (P<0,01), whereas the addition of 0.2 and 0.3 mg/ml saponin decreased ammoniaconcentrations by 1.69 and 16.50% (P<0.01) compared to the control. Microbial protein, cellullaseactivity and pH were not affected neither by saponin nor kind of feed. Protozoal numbers and ammoniaconcentration in the rumen were lower (P<0.01) with king grass as substrat than that with rice bran, orking grass: rice bran. In general, no interactions between saponin and kind of feed were observed, exceptfor ammonia concentration. It can be concluded that level of 0.2 mg/ml saponin have antimicrobialproperties, particularly in suppressing protozoa, which may prove beneficial to ruminal fermentation andmay lead to lower ruminal ammonia concentration, but it did not have negative effect on pH, microbialprotein and cellullase activity. King grass as a substrate decreases protozoa numbers and ammoniaconcentration.

Abstract

This study was carried out to determine the environmental pollution surrounding poultry production cluster (PPC). A cross-sectional survey on environmental pollution surrounding PPC was conducted in the districts of Subang and Ciamis, West Java Province, Indonesia. Information of farmers aspiration on environmental pollution and sanitation issues related to the existence of PPC was collected by semi-structured questionnaires. Ammonia gas (NH3) in feces was tested qualitatively, and ground water was analyzed for Coliform and Salmonella sp. contamination. The result showed that dust and ammonia gases from feces (Subang 300-450 ppm, Ciamis 25-525 ppm) pollute the environment and caused an unpleasant odor surrounding the pens. Fly population was increasing during the harvest time of chickens,causing community daily lives were not comfortable. Water quality surrounding PPC indicated that Salmonella sp. contamination was negligible however most samples from Subang and Ciamis were contaminated with coliform bacteria (<3 MPN/ml–27 MPN/ml). Improvement on management policy to reduce the environmental pollution is thus still needed to develop surrounding the PPC areas.
