Abstract

Ostrich (Struthio camelus) is a flightless and biggest bird, classified as Aves and originated from Africa . Although has been domesticated and fanned for more than 100 years, it is generally agreed that information on ostrich fanning technology is limited not only in Indonesia but also in overseas . Superiorities of ostrich over other birds are: (1) mature ostrich weight between 150-200 kg and 2-3 m tall, (2) live weight of 100 kg can be achieved before 12 months old, (3) digesting high crude fibre diet, (4) digesting feed efficiently, (5) may live up to 70 years old and (6) low fat, cholesterol and energy content of meat. The main source of income in a commercial ostrich farm in South Africa were from leather, meat and feather sales. Research on ostrich in Indonesia has to be well planned to obtain appropriate fanning and after harvest technologies suitable for the Indonesian environment as ostrich fanning had been just introduced in 1996.

Abstract

Ducks in Indonesia play roles in producing egg and meat. More than 19% of egg consumption were produced by ducks, however as meat source they only contributed 0.94% of total meat supply in Indonesia. Feed and feeding management are very important in duck farming as 70% of total production cost of egg and meat-type ducks accounted for  feed cost. Unfortunately, nutrient requirements for the Indonesian ducks were limited. Therefore, overseas nutrient recommendation may be used. Water is the most important nutrient for poultry including duck, therefore quantity and quality of water are very important to be considered in feeding ducks. There are various local feeds available in Indonesia to be used as duck diets. Quality of feed is very important in duck farm as the ducks is very sensitive to aflatoxin poison. The maximum safe level of aflatoxin in the diet was to be less than 40 µg/kg.   Key words. Duck, egg, meat, feed and nutrient

Abstract

Ducks produce egg, meat and feather. Egg is the main product of ducks for Indonesian communities. Duck farming produced eggs approximately 180,000 ton or equal to 16% of national egg production in 2005. Ducks also contributed 38,700 tons of meat or 3% of national poultry meat production or equal to 2% of national meat production. Besides egg and meat, duck farming also produced 269.4 tons of feather valued at US $ 294,800. All of those duck commodities were produced by 35 million of hearded ducks. Hearded ducks productivity were approximately 100 – 150 eggs/hen/year which were considered to be much lower than confined ducks productivity which were recorded at average of 253 eggs/hen/year. There are known several local Indonesian ducks which showing highly variable egg productivities. Various technologies are potential to be implemented by duck farmers to improve their duck-egg production. The improvement can be achieved by implementing breeding and nutrition technologies such as replacing the old hens with selected local duck breeds, feeding appropriate diets and implementing good management practices in their farms.   Key words: Duck, role, egg, meat, technology

Abstract

Livestock Recovery Programme on Merapi Disruption Area A series of volcano eruption of Merapi on October and November 2010 was one of the biggest eruptions since 1872 with around 275 people died, 576 people in hospital and 287.131 people were evacuated. This disaster has impacted to the threatened livestock subsector that cannot be from farmers in the rural areas, especially in the Merapi surrounding areas. The proportion of livestock to total population was 14, 39 and 21,5%, for beef cattle, dairy and buffaloes respectively. Total of cattle died were 2.907 heads and the district of Sleman suffered the highest loss in livestock deaths in which 43% of the threatened dairy population died. A various action program has been carried out to recovery, i.e. supply of concentrate and wafer plus, knock down barn innovation for dairy, along with supply of medicine and services for better life of livestock. Recommendations of medium and long terms action programme for rehabilitation and reconstruction of livestock farming include: repair on water supply, innovation of complete feed, forage rehabilitation plantation, composting management and biogas usage, knock down for dairy barn to anticipate the Merapi eruption in the future, and surveillance on the possibilities of contamination and strategic animal diseases. Rehabilitation and reconstruction effort may recover the farmer economic livelihood that has been devastated in a liable period of time. Key words: Merapi disruption, livestock recovery

Abstract

Feed cost is the major cost for duck-egg production which accounted to be more than 70% of total production cost. Feed efficiency of duck-egg production in Indonesia is low. The main reasons for the low feed efficiency (high feed conversion ratio, FCR) are (1) genetic trait (2) high feed wastage and (3) inadequate nutrient content of diet. An experiment was conducted to evaluate effect of restricted feeding of pelleted diet on Mojosari x Alabio (MA) cross-bred duck performances from 20-43 weeks old. The experiment was designed in a Completely Randomized Design. 156 MA cross-bred ducks were devided into three groups and fed three experimental diets: (1) 70%, 85%. and ad libitum. All experimental diets were fed to ducks for 24 weeks and feed intake, egg production, egg weight, FCR, molting and egg quality: egg yolk weight, albumen wight, egg shell weight and egg yolk colour score were measured as parameters. The results showed that the restricted feeding of 70% and 85% significantly (P<0.05) reduced egg production, egg weight and induced early molting but did not adversely affect duck livability and egg quality. MA croos-bred duck was more efficient by feeding ad libitum than the restricted feeding. FCR of duck fed 70% (6.38) was significantly (P<0.05) worst compared to FCR of duck fed 85% (3.68) and ad libitum (2.88).   Key words: Restricted feeding, MA crossbred duck, productivity and egg quality

Abstract

Screening for choosing the best bacterium and mold producing cellulase was carried out from eight xylanolytic bacteria and three cellulolytic molds isolated from termites. Each bacterium and mold was inoculated on the agar medium containing minerals and carboxymethylcellulose. The diameters of colony and clearing zones were measured after stained with Congo red. Four bacteria: Bacillus larvae XB 1-1, B. larvae XU 2-2, Bacillus PU 2-2, and B. pumilus PU 4-2 showing higher clearing zone ratio were further submerged cultured in PM medium containing 2% wheat pollard in the shaker incubator at room temperature, 150 rpm for 36 and 48 hours. The three molds: Aspergillus flavus S 13, MS 21, and Penicillium nalgiovense S 11 were also cultured in the same way as bacteria, but in Mandels medium containing 2% wheat pollard for three and five days incubation time. B. pumilus PU 4-2 and A. flavus S 13 produced the highest CMCase in each group respectively. All enzyme assays of A. flavus S 13 had higher activities than that of B. pumilus PU 4-2. The specific activity of CMCase, avicelase, FPase, and cellobiohidrolase were the highest on the enzyme of A. flavus S 13 produced from 3 days incubation time, while its β- glucosidase was the best for five days incubation. In term of activities, A. flavus S 13 had the highest ability to produce cellulase. The ability of B. pumilus PU 4-2 to produce cellulase and xylanase at the same time was an additional value.   Key words: Bacillus pumilus, Aspergillus flavus, cellulases

Abstract

Use of the rice bran as poultry feed is restricted by its high fibre content as poultry is unable to hydrolyse the fibre into available energy. This experiment was aimed The aim of this experiment was to investigate the effect of crude enzymes supplementation on performances of broiler chickens fed diets containing 30% rice bran. The experiment was based on completely randomized design with nine experimental diets. Diets 1-5 contained 5% less than recommended protein and energy, based on determined metabolizable energy (ME) content in the rice bran at 2040 kcal/kg, without taking into account on the beneficial effect of the enzyme supplementation. These diets were: 1. A control diet (D2040, without enzymes); 2. D2040 + E. javanicum (BS4) + P. nalgiovense (S11); 3. D2040 + BS4 + A. niger; 4. D2040 + BS4 + commercial enzymes (CE); 5. D2040 +  B. pumilus (PU4-2) + CE. Four other experimental diets contained the same protein and energy levels as in the diets 1-5, but had taken into account on the beneficial effect of the enzyme supplementation,. These diets were:  6. D2702 + BS4 + S11; 7. D2650 + BS4 + A. niger; 8. D2465 + BS4 + CE ;and 9. D2465 + PU4-2+ CE. Each experimental diet was repeated six times and each replication consists of 5 day-old broiler chickens. Results showed that FCR of the chickens fed D2040 + PU4-2 + CE  diet (FCR = 1.38) and D2465 + PU4-2 + CE diet (FCR = 1.46) were significantly (P < 0.01) improved compared to the control diet  (FCR = 1.64). This experiment strongly shows that supplementation of PU4-2 + CE enzymes significantly (P < 0.01) improved feed efficiency of the broiler chickens by 11-16%.
