酸化剂对猪生长性能、腹泻率及肉品质影响的Meta分析OA

In this study,Meta-analysis was used to explore the specific effects of acidifier feed additives on swine growth performance,diarrhea incidence and meat quality.A total of 62 sets of data(including 62 samples from the experimental group and 62 from the control group)were collected,covering aspects such as swine growth,diarrhea incidence,and meat quality.Sensitivity analysis and funnel plots were employed to assess the stability of results and identify publication bias.The results of Meta-analysis showed that the aver-age daily gain(ADG)and average daily feed intake(ADFI)of swines were significantly increased(P<0.05),and the feed to gain ratio(F/G)was significantly decreased(P<0.05).Meanwhile,the experimental group also significantly reduced the incidence of diarrhea incidence in piglets(P<0.05)and improved the overall health status of the swine herd.In addition,after adding acidifier,marbling,pH value and intramuscular fat content were significantly improved(P<0.05),and shear force,drip loss and cooked meat rate were signifi-cantly reduced(P<0.05).The results of the funnel plot indicate that the publication results are less biased and more robust.It is recommended to use an appropriate amount of acidifiers in swine produc-tion to improve growth performance and meat quality.
