BASA Fish Oil Nutritional Value Evaluation And Its Application In Weaned Piglets Diet

The objective of the present study was to:1) determine the digestive energy and metabolizable energy of soybean oil and basa fish oil for weaning piglets; 2) evaluate the effects for both of 2.5% or 5% of basa fish oil and soybean oil on growth performance and diarrhea incidence of weanling piglets. Two experiments were conducted. In experiment 1, fifteen piglets with initial bodyweight of 15 ±1.3 kg were divided into three treatment groups to fed control diets with no addition of fat, or fed diets with 5% inclusion of soybean oil or basa fish oil. After 5 days’adaptation to the diets,4 days’ feces and urine were collected from each piglet to determine energy content. Substituting method were used to calculate digestibility and metabolity of each diets. In experiment 2, seventy five weanling piglets with initial bodyweight of 11.02±1.20 kg were divided into five treatment groups to fed five diets,1) control diets with no addition of fat,2) control diets supplemented with 2.5% soybean oil,3) control diets supplemented with 2.5% basa fish oil,4) control diets supplemented with 5% soybean oil, 5) control diets supplemented with 5% basa fish oil. The experiment lasted twenty eight days, feed intake and weight gain were determined weakly to calculate average daily feed intake, average daily gain, feed conversion rate.Results showed that:1) The digestible and metabolizable energy was 30.08MJ/kg and 29.46MJ/kg for basa fish oil, respectively.; The digestible and metabolizable energy was 32.17MJ/kg and 31.34MJ/kg for soybean oil, respectively.2) as the increasing level of fat addition, the feed intake and average daily gain were not influenced in piglets fed soybean oil and basa fish oil.3) Diarrhea incidence of piglets were improved by BASA fish oil by 7.6% and 9.1% at the inclusion of 2.5% and 5%, respectively compared with soybean oil.Collectively, digestible and metabolizable energy was 30.08MJ/kg and 29.46MJ/kg for basa fish oil, respectively. Piglets fed diets with inclusion of basa fish oil did not improve growth performance.
