| Effect of activated clinoptilolite and inactive brewer’s yeast mixture on loin eye muscle and body indexes in fattening period |
| This study was conducted to determine the effects of dietary activated clinoptilolite and inactive brewer’s yeast mixture (CBY) on the loin eye muscle (MLD) and body indexes. For this purpose, a total of 48 Kivircik male lambs at the weaning age of 62 ± 4 days and with the initial live weight of 23.80 ± 3.19 kg were randomly allocated to one control group (CON) and three treatments groups (namely CBY-Ι, CBY-ΙΙ, and CBY-ΙΙΙ), each containing 12 lambs. 0, 1, 3, and 5 g/kg of CBY were added to the diets, respectively, as fed basis. The trial lasted for 63 days, of which 7 days were spent for adaptation to the diets and 56 days for the data collection. All the animals received 150 g of chopped alfalfa hay and their specifically formulated experimental diets ad libitum. There was no significant difference between the treatments in terms of MLD depth and fat thickness (FT) (p > 0.05). The addition of 3 and 5 g/kg CBY to the lamb diets increased the MLD depth (+1.87% in CBY-ΙΙ and +4.67% in CBY-ΙΙΙ) and decreased the FT (–13.29% in CBY-ΙΙ). Furthermore, a significant difference was observed between the treatments in terms of index of height (IH) (p < 0.05). It was concluded that adding 3 g/kg CBY to the lamb diets to increase the MLD depth, decrease the FT, and improve the body indexes may have some economic benefits in the fattening period. |
