Body weight, haematological indices and intestinal morphometric of broilers provided with diets containing formic acid, butyric acid or their blends

The study investigated the influence of dietary incorporation of formic acid, butyric acid or their blends on growth rate, haematological indices and intestinal morphometric of broilers. A number of 240 Lohmann MB-202 chicks were pass rounded to four dietary groups, including CONT (chicks taking in basal feed with no additive), BTRT (chicks receiving basal feed with 0.03% butyric acid), FRMT (chicks receiving basal feed with 0.1% formic acid) and BTRT+FRMT (chicks receiving basal feed containing 0.03% butyric acid and 0.1% formic acid). Weight of chicks and intake were measured every week, while blood sample was collected at day 21 and 35. At day 35, birds were slaughtered and small intestinal segments and digesta were collected. At day 21, body weight was bigger (P
