Effect of dietary humate supplementation on growth performance, carcass traits and intestinal microflora in local chicks
Abstract: The current study was carried out to determine the influence of dietary supplemented humate including humic, fulvic and ulmic acids and some microminerals on local chicks performance, carcass traits and intestinal micro flora of local chicks. A study was conducted with total 400 one day-old unsexed local chicks (El-Salam Strain). Chicks were allocated to four dietary treatments (H0, H1, H2 and H3 groups) as completely randomized experimental design. Feed and water offered ad libitum throughout experimental period (12 wks). A basal diet (H0), basal diet plus 0.10 (H1, 0.25 (H2) and 0.40% (H3) humate (BioFarm DRY. Humate, Farmavet International Inc., Kocaeli 41400, Turkey) were fed during experimental period. At the end of the trial (12 wk), 20 birds were slaughtered for measuring carcass traits. Feed intake and body weight were weekly recorded.
The results showed that body weight, feed conversion ratio and carcass traits were positively influenced by humates supplementation (0.25%) during the experimental period. Diets supplemented with humate (0.25%) enhanced the digestibility coefficients of most nutrients compared to the control. Feeding dietary humates led to detrimental reduction in total content of coliforms bacteria and bacterial total count, but the population of lactobacilli bacteria was slightly increased. Ideal pH values were slightly increased as dietary humate increased. Gradually. Blood content of total proteins were significantly decreased, while there was no significant effect on blood total lipids or cholesterol concentrations were found.
The results suggested that humate supplementation in diet of growing local chicks may improve the growth. rate as a result of the modification effect of humates on microbial populations of lumen.
