Influence of Achyranthes japonica extracts supplementation in the diets of finishing pigs

Abstract

Background Herbs and their extracts have been used for a long time in animal industries as alternatives to an antibiotic. Objectives This study was evaluated the effects of dietary supplementation of Achyranthes japonica extracts (AJE) on the performance and production parameters in finishing pigs. Methods Totally, 100 pigs with an average body weight of 50.33 ± 4.61 kg were used as a 10‐week feeding trial. Pigs (five replicates, three barrows and two gilts per pen) were allotted randomly to four treatments as the addition of 0%, 0.05%, 0.10% and 0.20% of AJE in basal diets. Results A linear increase (p < .05) in average daily gain was observed during week 5, week 10 and overall period, and a linear decrease (p < .05) was observed in the feed conversion ratio during week 5. A linear increase (p < .05) in dry matter, protein digestibility and faecal ammonia emission on week 5 and week 10 and a linear increase (p < .05) in serum total protein concentration on week 10 of pigs fed diets supplemented with graded levels of AJE was observed. Faecal lactic acid bacteria counts showed a linear increase (p < .05) on week 5 with the increasing levels of AJE. Conclusions In conclusion, there existed improvements in growth performance, nutrients digestibility, serum total protein, faecal coliform bacteria and lactic acid bacteria counts and faecal ammonia emission in the finishing pigs fed with AJE‐supplemented diet.
