ABSTRACT

 

Yadollahi A, Aboozari M, Filabadi RA, Kolaji J., Effect of tannic acid milk supplement on performance and digestibility in Simmental calves, Onl J Vet Res., 24(9): 542-547, 2020. We report effect of tannic acid supplement in milk on performance and nutrient digestibility in Simmental calves. Four groups of ten 10 day old Simmental calves were supplemented 2.5, 5 and 10g tannic acid/L milk for 60 days. We determined effect of tannic acid on feed intake, weight gain, conversion, digestibility and fecal consistency. Our results suggest that 5-10% tannic acid supplement daily for 60 days in Day old calves slightly improved feed intake (~4%), body weight gain (~12%) and feed conversion (~13%). We found no effect of tannic acid on digestibility of organic, crude matter or fiber content of feed given to calves. Compared with controls we found ~20% improvement in fecal consistency in calves given 10% tannic acid (P≤0.05).

 

Key words: Digestibility, Semintal calves, Fecal consistency, Performance, Tannic acid.
