|Abstract:||A study was carried out to assess the influence of potassium diformate on growth performance, digestibility of nutrients and carcass quality in Large White Yorkshire pigs. Thirty weaned male piglings with an average live weight of 13.0 kg were divided into three equal groups as uniform as possible with regard to age and body weight. Pigs were maintained on three experimental diets viz., Ti control standard grower (18 per cent crude protein and 3150 kcal/kg ME) and finisher ration (15.5 per cent crude protein and 3100 kcal/kg ME), T2 - control diet supplemented with 0.75 per cent potassium diformate and T3 - control diet supplemented with 1.5 per cent potassium diformate. The average daily gain of 465, 494 and 519 g were recorded for the groups Ti, T2 and T3, respectively. There was no significant difference (P>0.05) between the supplemented group and the group fed control diet. However, there was a trend for a higher growth rate of 6.2 per cent and 11.7 per cent, reported for T2 and T3 over those fed control diet. The average cumulative feed conversion efficiency were 3.97, 3.74 and 3.55 for the groups Ti, T2 and T3, respectively. Addition of potassium diformate at 0.75 and 1.5 per cent level in the diet of growing-finishing pigs had a higher (P<0.01) feed conversion efficiency over those fed control diet. There was no significant difference (P>0.05) between the supplemented groups. However, there was a trend for a higher feed efficiency for those fed 1.5 per cent potassium diformate supplemented diet. The digestibility coefficients for dry matter, ether extract, crude protein and nitrogen free extract were significantly higher (P<0.01) for pigs fed with diet supplemented with potassium diformate at both the levels (0.75 and 1.5 per cent). There was no significant difference between the supplemented groups. Dressing percentage, carcass length, back fat thickness, loin eye area and others were not significantly influenced (P>0.05) by the inclusion of potassium diformate at different levels. The costs of feed per kg live weight gain of pigs were Rs.32.82, 32.05 and 31.50, respectively for Ti, T2 and T3. The above results indicate that potassium diformate can be economically incorporated at 1.5 per cent level in the diet of Large White Yorkshire pigs.|
