Abstract

Based on rumen degradation rate, concentrates are divided into : slow degraded energy feeds, fast degraded energy feeds, slow degraded protein supplements, and fast degraded protein supplements. This classification is important to synchronize the presence of nutrients in the rumen used to stimulate rumen microbes growth . Rumen microbes-can be used as protein supplements for the host . Protein content, digestibility, and biological value of rumen microbes are about 65%, 75-85%, and 80%, respectively . Rice straw as an agricultural by product has a low protein content of not more than 7%, low digestibility, thus in the digestive tract, in rumen, and particle changes in rumen require about 81 .67 hours, 62.69 hours, and 1 .62% per hours, respectively. Rice straw utilization as feed needs supplementation and quality and digestibility improvement in the form of physical, chemical, biological, or combined. The physical treatment aims at reducing particle size or cell swelling . Reducing particle size of roughage will increase the rate of passage in the rumen, increase consumption, decrease digestibility, and reduce milk fat, while sodium hydroxide treatment will increase digestibility up to 100% without nutrient increase, however it is dangerous to human life and a pollutant for the agriculture field. Rice straw treatment using ammonia increase its digestibility and its nutrient . The biological treatment was conducted to change rice straw structure by enzyme lignocellulase and increase protein content with microorganism. Basically, the concept of biological treatment is restricted composing, conservation, and predigesting to increase quality. Recently, many commercial products have been developed for rice straw biological treatment orienting at predigesting of cellulose. The application of physical, chemical, and or biological treatment for agricultural by product is as component for complete feed Key words: Rumen Microbes, supplementation, predigesting

Abstract

The objective of this research was to analyze the effect of coconut sugar paste in naturally fermented trash fish ensilage on chemical change. Grinded trash fish (Pomadasys macullatus) was mixed with coconut sugar paste (0, 15, 30 and 45%/kg fresh trash fish) without inoculation in plastic bag. Anaerobe incubation was conducted at room temperature (29°±1°C). Chemical change (pH, lactic acid, ammonia, non-protein nitrogen, peroxide value and free fatty acid) was observed during fermentation period of 0, 4, 8, 12, 20 and 24 days. The experiment which had a completely randomized design to select the best amount of coconut sugar paste and fermentation period in trash fish ensilage. Fresh trash fish and fermentation product (trash fish silage) determined by the proximate analysis (dry matter, ash, crude protein and crude fat). Result indicated that the pH decreased remained constan at 4,4 after 16-day fermentation. Lactic acid, ammonia, non-protein nitrogen, peroxide value and free fatty acid during fermentation significantly increased due to different levels of coconut sugar paste and fe rmentation period. Conclusively, coconut sugar paste at the level of 15%/kg fresh trash fish was the best combination in natural fermentation with 16-day fermentation period and the product was potential protein source (45% DM) for animal feed. Key word: Trash fish, coconut sugar paste, silage, fermentation.

Abstract

Fermented complete feed (CF) based forage-fodder and agricultural by product as feed for ruminants can be implemented in the household and industrial purpose. Complete feed technology is one of alternative to solve the problems of stock and quality of feed. The nutritional value can be set by determine the number and type of mixture, livestock will not has an opportunity to choose so that it can minimize residual feed, practical, and can be stored for long periods. Fermented complete feed very much match to be implemented in the dry season or in the emergency situation. During Merapi Volcano eruption in 2010 was one of moment which is need CF technology. Rice straw can used for CF that can be socked during dry season, also the quality might improve (from 3—4% of crude protein content became 7—8%) with addition of rice brand or other ingredients. Fermented complete feed based on rice straw, forage-fodder or agricultural by product has a multifungtion in the emergency situation, reduce disaster risk, and feed security conservation.

Abstract

Two plants as condensed tannin (CT) sources were supplemented to protein trash fish silage (TFS) to observe their effect on in vitro ruminal fermentation product, micobial protein synthesis, and   digestibility. CT supplementation on protein trash fish silage was on control proportion (0), under optimum level (2.0%), at optimum level (4.0%), and above optimum level (6.0%) of g TFS); of protein precipitation of bovine serum albumin (BSA) with CT from L. leucocephala; and under optimum level (1.5%), at optimum level (3.0%) and above optimum level (4.5% of g TFS), BSA protein precipitation with CT from C. calothyrsus. The effect on degradation in ruminal fluid and ruminal fluid followed by incubation in HCl-pepsin was evaluated using a modified two-step in vitro method. The CT level of L. leucocephala and C. calothyrsus was 4% and 6%, respectively with protein precipitation BSA was 26.25 and 31.77 g BSA/g CT, respectively. CT supplementation to trash fish silage, ruminal fermentation product (NH3-N, C2, C3, and total VFAs) and digestibility (DM and OM) decreased (P<0.01) and increased (P<0.01) total CP digestibility (in HCl-pepsin). The difference was attributed to CT source without affecting ruminal microbial protein synthesis. CT of L. leucocephala was better in increasing total protein digestibility (70%) than that of C. calothyrsus  (15%). It indicated that CT of C. calothyrsus was less effective in protected TSF protein degradation in rumen compared to that of L. leucocephala.
