The main objective of the present study was to investigate the effect of incorporation of graded levels of Phalaris minor seeds (a weed in wheat fields) in the total mixed ration on in vitro nutrient digestibility and rumen fermentation pattern using buffalo inoculum. Maize grain based conventional concentrate mixture was prepared and maize grains in the concentrate mixture were replaced by Phalaris minor seeds at graded levels of 25, 50, 75 and 100 per cent. Maize based concentrate mixtures were then mixed with oven dried oat fodder and wheat straw in 40:40:20 ratio, respectively to formulate five total mixed rations. The roughage to concentrate ratio of diet was kept at 60:40.The nutritional worth of various total mixed rations formulated was assessed by in vitro gas production technique. It was observed that net gas production and methane production was depressed (P<0.05), when maize grains in the concentrate mixture were completely replaced by P. minor seeds. Similar trend was observed in the in vitro digestibility of nutrients. However, there was no adverse effect of replacing maize grains with P. minor seeds up to 75 per cent in the concentrate mixture on in vitro dry matter and organic matter digestibility. The inclusion of P. minor seeds in total mixed ration did not have any adverse effect on fermentation parameters. Hence, it was concluded that P. minor seeds could be considered as promising energy supplement for livestock and can replace conventional cereal grains viz., maize upto 75 % in the total mixed ration without any adverse effect on nutrient digestibility and fermentation pattern.
