Utilization of tomato (Lycopersicon esculentum) pomace with or without waste bread in the ration of growing and adult male buffaloes. Animal Nutrition and Feed Technology, 23: 13–24. This study was taken up to assess the impact of tomato pomace (TP) with or without waste bread (WB) in the total mixed ration (TMR) on the nutrient utilization and performance of adult buffaloes and buffalo calves. The TP is a rich source of CP (21–22%), EE (10.5–11.5%) and 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) an antioxidant and other bio-active compounds. In experiment-1, twelve male Murrah buffaloes (Age around 3 years, BW 444.2+4.76 kg) divided into 3 equal groups were offered 2.5 kg of either control concentrate mixture (CCM) or sun dried TP replaced 50 or 100% of CCM on nitrogen basis for 45 days. The daily DM intake and digestibility of nutrients were comparable except that of CP which was depressed (P<0.05) and that of hemicellulose improved (P<0.05) in adult buffaloes fed TMR containing TP. The N-retention was comparable in all the groups. The incorporation of TP in the ration of rumen fistulated male buffaloes resulted in increased (P<0.01) rumen volume and decreased (P<0.05) dilution rate, without affecting rumen out flow rate. The TCA precipitable N concentration in the rumen was improved (P<0.05). In experiment 2, sixteen male Murrah buffalo calves (1.2 to 1.3 years old, weighing 262.7+9.10 kg) divided into four equal groups were fed for 90 days either CCM or wheat in CCM was replaced completely with waste bread (WB) on N-basis or in the third group besides replacing wheat with WB, mustard cake and rice bran were completely replaced with TP and in the fourth group the animals were offered only TP. The daily DM intake, digestibility of nutrients, N-intake and total N retention were comparable in all the groups. The average daily gain in weight of buffalo calves of all experimental groups was improved considerably as compared to control group, but the differences were non-significant. It was concluded that tomato pomace a rich source of protein, ether extract and bio-active compounds can replace concentrate mixture on N basis from 50–100% supplemented with or without detoxified waste bread (a rich source of cooked starch) both in growing and adult buffaloes without any adverse effect on the nutrient utilization, rumen outflow rate and performance of animals.
