A meta-analytical study about the relation of blood plasma addition in diets for piglets in the post-weaning and productive performance variables

摘要: The meta-analysis was used to evaluate the performance of piglets in post-weaning period, without imposition sanitary challenge and fed diets containing blood plasma, obtained by spray-dried process (SDBP). Piglets are faced with normal challenges period such as environmental stress substitution liquid diet a solid one. References regarding were disregarded this study. Only data expected considered. Data from indexed journals information extracted material, methods results sections pre-selected scientific articles. First, database analyzed graphically observe distribution presence outliers. Afterwards correlation analysis variance–covariance analyses carried out. contained total 23 average initial weight 8.02 kg (4.00–9.28 kg) age 27 days (14–32 days). duration feeding plasma (SDBP) 9 (6–28 SDBP increased feed conversion 20.2% (Po0.05) during period. Feed 10.2% higher for animals SDBP. Average daily gain intake not affected (P40.05) entire but supplementation influenced Better than those up 35 added supplementation. In early postweaning weaned age, positively conversion.
