Effect of Probiotic Cell Wall Supplement on some Technical-Economic Indicators ofGrowing-fattening Pigs
Keywords
Probitotic cell wall, growing - fattening pig, performance, benefit
Abstract
Study was carried out to evaluate effect of probiotic cell wall (Lactobacilus rhamnosusand Saccharomyces cerevisiaecell walls - IV bio-product) supplement in growing-fattening pig diet on villus development, intestinal microbial change and economic efficiency. The rexperiment was conducted on 84 weaning pigs (PiDuxLY) (6.6±1.45kg), which were randomly assigned into 4 groups, viz. control group (ĐC), experimental groups IV0.01, IV0.03, IV0.06, with 3 replications (7 pigs/replication) to receive 4 dietary treatments with different levels of IV bioproduct at 0%, 0.01%, 0.03% and 0.06%. Results showed that the probiotic cell wall mixture did not affect the intake but improved growth rate and feed efficiency. The IVbioproduct supplement also increased villus height but reduced Crypt depth. Pigs fed 0.03%-0.06% IV mixture of supplement diets showed high population of Lactobacillusbut lower population of E.coliand Coliformin the jejunum and cecum. Using the Solver optimal analysis in order to obtain optimal live weight gain, FCR and profit, the optimal level of probiotic IV mixture supplement in pig diet should be 0.048%-0.051% (best at 0.05%).
