Performance of four-breed crossed growing-finishing pigs fed wheat-based rations with different enzymes

The initial weights of pigs in the two treatments were not statistically different. Pigs in treatment 1 had an average initial weight of 23.125 kg while pigs in treatment 2 had 23.562 kg. For the first 30 days on test (starter stage) pigs in treatment 1 weighed 49.975 kg. The corresponding average d...

Summary:The initial weights of pigs in the two treatments were not statistically different. Pigs in treatment 1 had an average initial weight of 23.125 kg while pigs in treatment 2 had 23.562 kg. For the first 30 days on test (starter stage) pigs in treatment 1 weighed 49.975 kg. The corresponding average daily gains for the period were 0.916 kg and 0.877 kg and the feed efficiencies were 1.641 and 1.763. Twenty days later (end of grower stage) pigs in treatment 2 were slightly heavier than pigs in treatment 1 with average daily gains of 0.856 kg and 0.897 kg, respectively and feed efficiencies of 2.261 and 2.342. At the finisher stage (30 days), treatment 1 pigs garnered an average weight of 86.700 kg with an average daily gain of 0.632 kg and feed efficiency of 4.020. The corresponding values in pigs of treatment 2 were 86.225 kg, 0.61114 kg and 4.006. For the whole experiment, the average daily gains of pigs in treatments 1 and 2 were 0.802 kg and 0.786 kg, respectively, with corresponding average feed efficiencies of 3.547 and 3.760 and backfat thickness of 15.656 mm and 14.217 mm. All the differences between treatments in all stages of growth and for the whole duration of the experiment were found statistically non signficant (P.05). Cost of the enzyme per inclusion rate spelled difference between the two treatments. Treatment 1 which used Enzyme A was favored in terms of cost and being used by the Nena-Ling Swine Farm since after the conduct of the experiment
