Background: Using crop residues in goat rations is essential to prevent the shortage of fodder for goats in rural areas. To overcome the problems of low acceptability, digestibility, low nutrient contents of crop residues, preparation of crop residue based complete feed pellets is the best way. The aim of this study is to evaluate the effect of feeding gram straw-based complete feed pellets on the growth performance, nutrient utilization and rumen fermentation of goats. Methods: The goats in groups I and II were fed ad lib supernapier hay + 300 gm concentrate daily and ad libitum gram straw-based complete feed pellets with roughage to concentrate ratio of 70:30, respectively. The growth performance, nutrient utilization and rumen fermentation study, along with an estimation of hematological and blood biochemical parameters, were carried out in this experiment. Result: Significantly better growth performance, nutrient utilization, rumen fermentation and low cost of production was found in goats of group II (fed gram straw-based complete feed pellets) with the non-significant difference in body condition score, rumen motility and hematological parameters in goats of group II than group I. The blood glucose values found significantly more in group II as compared to group I. Feeding gram straw-based complete feed pellets improved performance, nutrient utilization and proved to be economical.

Livestock emit large quantities of methane as part of their natural digestive processes. Livestock is a significant source of methane, a potent greenhouse gas, in agriculture. Carbon dioxide is much more abundant than methane in the atmosphere. Methane, on the other hand, traps 30 times more heat than carbon dioxide. Methane (CH4) is the main component of natural gas and a powerful greenhouse gas (GHG). After escaping into the atmosphere, greenhouse gases act as a shield, insulating the Earth and trapping energy while slowing the rate at which heat leaves the planet. The greenhouse effect has become stronger and more constant over the last few decades as greenhouse gas emissions have increased. It is leading to global warming, which is a concerning situation. As a result, methane production and emissions from the fermentation of feed and fodders in the ruminant digestive tract must be reduced. This analysis discusses nutritional manipulation in ruminants as the best method for reducing methane production and emissions.
