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

Publisher : Indonesian Animal Sciences Society

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.

One of energy sources for feedingÂ dairy cow is fat or oil, however, inclusion of fat or fatty acid at high level (>5% in the diet) may cause negative effect on rumen fermentation. Fat or fatty acid, therefore should be protected from its degradation in the rumen. The aim of this experiment was to evaluate protected product of palm oil fatty acid (Calcium fatty acid) made in the institute as feed supplement given on top of the ration. The first experiment was in vitro experiment using rumen liquor. Feed without and with Calcium fatty acid (Ca-FA) was incubated in buffer-rumen liquor and pH, total gas, ammonia and in vitro digetibility were measured. The second experiment was feeding trial with two treatments using 12 FH dairy cow divided into 2 groups with diet containing supplemntation 300 g of Ca-FA and other group is control treatment without supplementation. The feed was total mixed ration, comprises of elephant grass, ground corn, soybean meal, wheat pollard and coconut meal with protein content 15.1% and Net Energy for Lactation 1.53 Mcal/kg.. Feed was given to cow one month before parturition until 120 days of lactation period. Milk production was recorded daily. Faeces collection was done at the end of the experiments for 1 week to calculate total tract digestibility. The result of the in vitro experiment showed that no negative effect on in vitro rumen fermentation except higher digestibility (DMD Ca-FA addition vs control were 58.52% vs 53.99%) occurred due to addition of Ca-FA. The addition of Ca-FA increased milk production (11.41 vs 10.74 litre/day), but no effect on intake, total tract digestibility and milk quality, higher body weight of cow than control cow showing the benefit of using Ca-FA in the diet of dairy cow. In conclusion supplementation of Ca-FA at 300 g would be beneficial to increase milk production without negative impact. Key Words: Calcium-Fatty Acid, Dairy Cow, Milk, Production, Quality

The objective of the research was to improve the nutritive value of PKC through fermentationÂ and to evaluate its degradation characteristics in the rumen and post rumen digestibility as a protein feed source for ruminants. PKC was fermented using Aspergillus niger, Trichoderma viridae and Aspergillus oryzae. To evaluate the in sacco rumen degradability, 2 rumen fistulated females Fries Holstein 3.5 years old were used. Samples were incubated in the rumen for 0, 4, 8, 12, 16, 24, 48 and 72 hours. Determination of dry matter (DM) degradation characteristics value and crude protein (CP) in the rumen was calculated based on formula y = a + b (1 - e-ct). The experiments were conducted using a completely randomized design with four replicates. The results showed that fermentation increased protein content of the PKC by 79.21% with the highest increase from fermentation using Aspergillus oryzae (88.34%). DM and CP degradability âin the rumen and post rumen of fermented PKC was affected by type of mold used for fermentation. Fermentation increased the amount of water soluble DM (a) of fermented PKC with average of 46.7%, but the value of insoluble but degradable fraction in the rumen (b) was decreased. Fermentation by molds resulited in the reduction of fractionÂ of insoluble CP but degradable (b) in the rumen by 50.42%. PKC fermentation by Aspergillus oryzae resulted in the higest CP degradability in the rumen and post rumen. It can be concluded that PKC has a high contentÂ of degradable CP in the rumen even without fermentation. Protein source from PKC fermented using Aspergillus oryzae categorized as the best source of feed protein in terms of increasing CP content and digestibility.
