ThesisItem Open Access EFFECT OF POLY-HERBAL FORMULATIONS ON HEALTH AND PRODUCTION PERFORMANCE OF POST-WEANED PIGLETS(West Bengal University of Animal & Fishery Sciences, Kolkata, 2023) SAHANA, MITA; Batabyal, Subhasis; Bag, Sadhan; Naskar, Syamal; Maity, ApratimWeaning condition is one of the critical and challenging phases of piglet where they get separated from mother and exposed to different environment. Sudden and abrupt changes in the total environment lead to the increase physical stress that leads to various diseases diarrhea to the piglets. Use of phytogenic feed additives other than antibiotics is safe not only to the livestock, but also to the consumers and environment. Experiments were conducted to evaluate the effect of Polyherbal formulations (herbs extracts mixture) on growth performance, blood characteristics, blood biochemical profile, Phytochemical analysis and fecal microbial shedding in weanling pigs. A total of 84 Ghoongroo piglets with average body weight 7.6± 0.6 kg were selected after weaning at 42 days and randomly allocated to 3 treatments. Treatments followed a 2× 2 factorial design with 2 levels of PHF-I and PHF-II (T1 & T2) with three different concentrations (100mg/ BW, 200mg/BW 250mg/BW). At initial weeks piglets were fortified with PHF supplemented diets that led to a lower (P <0.05) average daily feed intake (ADFI) but enhanced the feed conversion ratio (FCR) than the control group. But in later stage, at the age of 8th and 9th weeks, there was a sharp increase in weight gain from 10.54±0.67 kg to 17.31±0.56kg.In case of blood profile, significantly higher (P>0.05) WBC values in T1 group as compare to T2 group. Whereas, no significant difference was found between T0 and T1 groups were recorded. There was no significant variation in biochemical profile of blood parameters among groups. In conclusion, administration of PHF in weaning piglet’s diet had effect on the growth performance. However, the beneficial effect on WBC increases, lymphocyte and fecal E. coli concentration suggested that these kind of PHF have a positive role on growth performance of weaning piglets. Data analysis revealed that there was no significant difference between two treatment groups but significant difference was observed between the doses. Treatment group (T1) showed to reduce the bacterial load with various dose concentration than treatment group (T2).From this result, it can concluded that there was positive impact of herbal formulation for reducing the bacterial loads of post-weaned piglets and thereby, occurrence of diarrhea was drastically reduced.
