| ABSTRACT This study investigated the effect of both high dietary energy, as dry fat (MagnapacTM), and protected methionine (SmartamineTM) on growth, feed intake, feed conversion efficiency, trace mineral concentrations in blood serum and some tissues of growing Baladi kids. Twenty Baladi kids (3 to 4 months old and 24.64±3.0 kg average body weight) were distributed equally into four treatment groups as follow: control group given the standard requirements of NRC (1981) and tested groups were given high energy (3.0 Mcal ME/kg DM) without (T1) or with 2.5 g methionine/head/day (T2) or 5.0 g methionine /head/day (T3) as SmartamineTM. Results indicate that feeding Baladi kids high energy and protected methionine didn't lead to increase total weight gain, feed intake, and feed conversion efficiency. Treatments didn't cause any significant effect on dressing and organs percentage except the kidney. The omental fat percentage were significantly (P<0.05) increased with feeding high energy without or with 2.5 g/h/day protected methionine compared with the control, but intake of high protected methionine (5 g/h/day; T3) caused a significant reduction in omental fat compared with T1 and T2. Moreover, a significant effect of treatment on kidneys' cobalt, zinc and iron concentrations were found with variable changes for each mineral within groups. Copper concentration in blood serum showed significantly higher values for the final blood sampling of kids from T1 and T2 compared with the control and T3. In conclusion, feeding Baladi kids high energy without or with methionine as SmartamineTM didn't cause any significant improve on their performance in term of growth and feed conversion, but affect the omental fat percentage and some trace minerals concentrations. Moreover, the recommended NRC requirements for goats of energy and protein cover Baladi kids requirements for maximum growth and productivity. | ||||
