Feather, a waste product of chicken is a potencial protein source for animal feeds. The average production of feather is 6% of the life weight of the chicken. Broiler population in Indonesia in 2003 was 917,707,000; for DKI area was 1,360,000 while for West Java was 308,021,118. Research results indicate that chicken were slaughtered at 35 day of age with the range of body weight of 1 to 2.2 kg. The number of broiler slughtered every month in Jakarta is 4,679,500 head, resulted in feather of 350 ton/month while for Bogor area the number of slaughtered broiler is 1,255,000 head/month, produce feather of 135 ton/month. Feather meal can be used as protein source in ruminant feed as much as 40%. Key words: Feather meal, crude protein, ruminant feed stuff

The Processing Technology of Feather Meal and Its Use as a Protein Source in Ruminant Ration Wisri Puastuti

Feather meal protein contains high level of keratin, which consists of 14% disulphide cystine, therefore feather meal protein is difficult to be digested by proteolytic enzymes. Feather meal must be processed before being used in the ration, because the digestibility of unprocessed feather meal is very low (5.8%). There are four processing methods of feather meal, i.e. physical, chemical, enzymatic and microbiological. The aim of these processings is to alleviate or break down the bonds in the keratin such as disulphide, ionic, ester and hydrogen bonds. Processed feather meal is known as hydrolyzed feather meal (HFM). Although the processing methods of feather meal produce different quality of HFM, the utilization of HFM in ruminant ration results in a better response than conventional protein resources. HFM has higher level of crude protein content (74 – 92%), rumen undegradable protein (70%) and post rumiral digestibility (57 – 78%) than soybean meal has. The utilization of HFM in ration up to 8% of dry matter can substitute soybean meal and the use of 2 – 3% HFM improved milk production in dairy cow and daily gain in sheep and cattle. Key words: Hydrolyzed feather meal, protein, ruminant, processing technology

Potency and Utilization of Cocoa Pod Husk as an Alternative Feed for Ruminants Wisri Puastuti; IWR Susana

Cocoa pod husk (CPH) is potential as an alternative source of feed for ruminants due to its quantity and quality. The availability of CPH in Indonesia during the harvest season is abundant and able to feed around 635,305 animal unit (AU) per year. Cocoa pod husk as a feedstuff which contains crude protein between 6.80-13.78%; NDF 55.30-73.90% and ADF 38.31-58.98% is a source of fiber and can replace grass. However, CPH also contains antinutritional compounds such as lignin, tannin and theobromine. In order to optimize the use of CPH as feed, treatments are needed to improve the nutritive value and digestibility, to reduce negative effects and to extend shelf life. Processing methods can be conducted physically, chemically and microbiologically. Processing can improve the nutritional value of CPH especially the protein content. Feeding livestock using processed CPH showed better weight gain than that of unprocessed CPH. Besides, the attempt to utilize CPH as feed can overcome the shortage of forage, especially during dry season and increase ruminant productivity around the area of cocoa plantations. Key words: Cocoa pod husk, alternative feed, processing, ruminant

Manipulation of Bioprocess in Rumen to Improve Fiber Feed Utilization Wisri Puastuti

Ruminant has a unique digestive organ that has big capacity to digest fiber. The digestive process includes the interaction of feed, rumen microbe and animal itself. Fementative digestion gives an advantage for ruminant as majority of feed consists of fiber, i.e: cellulose, hemi cellulose and xylan. Rumen microbes have an important role to digest fiber. Rumen microbes could be manipulated by several strategies to increase microbial protein synthesis and microbial activity. Feed supplement could stimulate growth and activity of rumen microbes, while buffer could stabilize the rumen pH and also the fermentation. Defaunating agent was given to control the existence of rumen microfauna (protozoa) so increase the population of bacteria. Essensial amino acid was used as a growth factor of rumen microbe the amino acid or its precursor could be given as supplementation. Feeding probiotic could maintain anaerob condition in the rumen, and caused population and activity of rumen microbe increased. Addition of micro mineral or enzyme could improve the fermentation and feed degradation in the rumen, hence, improved feed intake and animal productivity. Key words: Rumen microbe, fiber source, manipulation, digestion
