Effect of high-energy diets on live weight change in sow

An experiment was carried out on Large White Yorkshire sows for a duration of 63 days at the Centre of Pig Production and Research, Mannuthy to elucidate the impact of higher feed energy levels through corn oil supplementation. Eighteen Large White Yorkshire pregnant sows were selected three weeks before the anticipated date of parturition and were divided into three uniform groups of six each and were allocated the treatments, T1{(Control ration (18% CP and 3280 kcal/kg ME as per ICAR, 2013)},T2{(Control ration +1 % Corn oil (w/w) (18 % CP and 3365 kcal ME/ kg feed)} and T3 {(Control ration + 2 % Corn oil (w/w) (18% CP and 3450 kcal ME/kg feed)}. The dry matter intake of the sows of the three groups was similar (p>0.05). At 42 days of lactation, the lactational loss in body weight of sows was statistically similar (p>0.05).
