• Cannery and fruit wastes
• In sacco degradability
• Mineral profile
• Protein fractions
• Water soluble nutrients

This study was taken up to assess the nutritional worth of cannery and fruit wastes for ruminants. Amongst the cannery wastes, pea pods (PP) had the highest CP content, sarsonsaag waste (SSW) had that of cell wall constituents (CWC). Carrot pulp (CARP) had the lowest CP, NDF, ADF and ADL contents. The water soluble sugars (WSS) were highest in CARP, while the true protein content and total phenolics were highest in citrus pulp without peels (CPWP). The in-saccoDM degradability revealed that CPWP had the highest effective degradability (ED) and low rumen fill values, which was responsible for higher DM intake potential and nutritive index value as compared to other cannery wastes. Amongst the fruit wastes, muskmelon peels (MMP) had the highest CP and CWC. The WSS were highest in MMP, the true protein in watermelon peels (WMP) and phenolics in banana peels (BP). WMP had the highest ED and the lowest rumen fill value, which was responsible for higher DM intake potential and nutritive index value. The relative proportion of albumin was highest, followed by that of glutelin, globulin and prolamin in all the cannery and fruit wastes. Most of these wastes could meet the daily requirements of macro and micro elements for ruminants, except Ca in SSW; Mg in MMP; Fe in CARP and BP; Cu in CARP, CPWP, BP and MMP; Zn in CARP and BP were higher than the maximum tolerance limit. None of the wastes contained the heavy metals above the maximum tolerance limit. It was concluded that most of the tested cannery and fruit wastes could serve as excellent alternate feed resource for ruminants.
