Abstrakt: In Kerala and other South Indian States, the ayurvedic by-products are widely available which can adequately be incorporated into pig diets. The objective of this study was to determine the effect of dietary incorporation of cooked barley residue and spent grapes on feed intake, growth performance, and nutrient utilization in sows and their piglets. Using completely randomized design (CRD), fifteen (15) Large White Yorkshire (LWY) pregnant sows with an average body weight of 180.53 kg, 3 weeks before the estimated date of farrowing, were randomly allotted to one of three treatment groups. The dietary treatment groups consisted of T1 (control), fed with a ration containing maize and soya bean meal of 18% CP and 3265 kcal/kg ME, T2 with a ration containing cooked barley residue replacing 25% maize in control, and T3 with a ration containing spent grapes replacing 25% maize in control ration. Data on average daily feed intake (ADFI), fortnightly bodyweight of sows and their piglets were recorded for 63 days. Also, the average daily gain (ADG), feed conversion ratio (FCR), and cost of feed per kg of weight gain of the piglets were calculated. The result showed no significant (P > 0.05) dietary treatment effects on average weekly dry matter intake and fortnightly average body weight gain among the sows in all the three groups. Piglets showed no significant difference (P > 0.05) in total dry matter intake (DMI), total body weight gain, ADG, and FCR among the three groups during the entire study period. No variations were observed for the apparent digestibility of nitrogen-free extract and the availability of magnesium in the three rations. The cost of feed per kg weight gain was lower in piglets belonging to T2 and T3 than the control (T1), though not significant statistically (P > 0.05). It is, therefore, concluded that cooked barley residue and spent grapes could be included up to 25% in the ration of sow and their piglets by partially replacing maize without affecting their overall performances.
