Nutritional Evaluation of Swine Waste as Livestock Feed

The study was taken up to assess the nutritional worth of swine waste (faeces) in the ration of buffaloes. The sundried swine excreta was observed to be a good source of nutrients viz. CP (17.88%), Ca (1.97%) and P (1.08%). The digestion kinetic parameters for DM of sundried swine waste assessed by in sacco technique revealed that sundried swine waste had 51.39% total degradable fractions, 45.06% effective and 63.71% true degradability. Keeping in view the promising preliminary in-sacco evaluation, the sundried swine waste was evaluated in the ration of buffaloes. Eight, 4–5 yr old male Murrah buffaloes of 450.8±4.8 kg body weight were randomly distributed into 2 equal groups. Animals in both the groups were fed iso-nitrogenous and iso-caloric ration containing 2 kg either conventional concentrate mixture or concentrate mixture containing 30% swine waste supplemented with ad-lib naturally fermented wheat straw with urea for 9 days and 2 kg available green fodder. The daily DM intake, digestibility of nutrients, N-retention and apparent biological value were comparable in control and experimental diet containing swine waste. It was concluded that swine waste can be incorporated in the concentrate mixture up to 30% on N basis without any adverse effect on the health or nutrient utilization in adult male buffaloes.
