Effect of application of fresh tomato pomace on growth performance and blood metabolites of Holstein male calves

The use of agricultural residues for feeding of livestock and poultry play an important role in reducing production cost.
This experiment was conducted for evaluation the effects of different levels of tomato pomace (TP) on dry matter intake, body weight gain and blood metabolites of male Holstein calves.
This research was conducted using 12 Holstein male calves in a Completely Randomized Design with 3 treatments and 4 calves in each group. Experimental diets were 1) control (no TP), 2) diet with 8% TP on dietary dry matter (DM) basis and 3) diet with 16% TP on dietary DM basis.
Using TP had significant effects on body weight gain and feed intake and feed conversion (FC) ratio (p It can be concluded that up to 8% of TP successfully can be used in beef cattle diet without any undesirable effects on animal production.
