Abstract

In high protein feeds, plant proteins may be shielded from degradation in the rumen by lignification of the cell wall or because of the present of plant secondary compounds e.g. tannin, which is present in most of the leguminous trees/shrubs. Thus it might have an effect on organic matter degradation and the pattern of other end product of rumen microbial fermentation (VFA, NH3, microbial cell, CH4 and total gas). The in vitro method was used to determine the organic matter degradation and the pattern of rumen fermentation end product of high protein feeds, namely Leucaena leucocephala, Gliricida sepium and Calliandra calothyrsus. The results shows that Gliricidia has the highest amount of OM degraded (505 mg); microbial cell and NH3 produced (2676 g and 1.91 mmol/100 mL) than followed by Leucaena (423 mg; 2656 g; 1.61 mmol/100 mL) and Calliandra (340 mg; 2644 g; 1.61 mmol/100mL), but Gliricidia produced the lowest amount of gas total and CH4 (0.192 mL and 0.07 mole per mg OM deraded) then Leucaena (0.249 mL and 0.097 mole per mg OM deraded) and Callliandra (0.196 mL and 0.126 mole per mg OM deraded). In conclusion, Gliricidia is more efficient in term of using the dietary energy for the animals’ production compared to the Leucaena and Calliandra.

Abstract

Changing in atmosphere condition is affected by the quantity of gases produced from all activities on the earth. Gases that have effects  on  global  warming  are  CO2,  N2O,  H2O,  and  CH4  (methane).  Among  other  sources  of  methane  are  enteric fermentation of organic material from ruminants and feces decomposition. Methane production from ruminants is affected by several factors such as breed/type of animal, feed quality, environmental temperature and physiological status of the animal. Energy as methane in ruminants may reach 2 to 15% of the total energy consumption. To reduce the emission of methane from ruminants, it is necessary to apply a strategic feeding system for more efficient utilization of feed.   Key words: Methane, global warming, ruminants, rumen fermentation

Abstract

The acceleration program to meet beef self sufficient in 2010 is expected to increase animal protein consumption of Indonesian people in order to be equal with other countries as well as to improve the livestock farmer’s income. The main objective of the program is to increase cattle population. Since the availability of forage and grassland is limited, beef cattle development is driven to the crop and plantation integration approach by using their by-product as cattle feed. Crop and plantation by-products, generally are considered to be fiber source with high lignocellulose’s and low nutritive value. Feeding high fiber would increase methane gas production, and faeces and grass cultivation also contributed on greenhouse emission. Methane is one of the main greenhouse gases contributed by agriculture sector; increasing beef cattle population using high fiber feed is predicted to increase methane production. Good management is expected to improve productivity and to reduce methane production on livestock. Some efforts could be done such as good feeding management and nutrition manipulation, environment friendly  cattle  waste  management,  improving  management on  roughage  cultivation,  and  improving  management  on  cattle production.   Key words: Beef cattle, agricultural by product, methane, global warming
