Article No.: 011622003 Type: Research |
12 Yorkshire barrows with initial BW of 23.9 ± 1.1 kg were assigned to two dietary treatments with six replications per treatment. The two diets were formulated in accordance with the principles of the substitution method. Diets’ dry matter (DM) digestibility, animals’ performance, the minerals’ apparent and true digestibility (AD and TD) values as well as their endogenous fecal losses (EFL) were investigated. The pigs were randomly allotted to their individual feeder pens which enabled individual pig fresh fecal sample collections. The experiment was designed as a completely randomized design (CRD) and lasted for 15d. Results showed that the DM digestibility of diet 1 (78.7%) was significantly (P < 0.05) lower than that of diet 2 (85.6%). However, animals on diet 1 had better (P < 0.05) average daily gain (ADG) and feed efficiency (FE) compared with animals on diet 2. The AD values of Se (73.9%) and Zn (9.5%) were significantly (P < 0.05) lower than their TD values of 82.1% and 15%, respectively. Se and Zn EFL were 0.00004mg and 0.01mg/kg of DMI, respectively. It was concluded that the TD values of these minerals be employed in diet formulations instead of their AD values as to avoid their mutual antagonism during metabolism and thus reduce their levels in the animal manure. |
