Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protein (level 1) and other nutrients requirements. T2: ration formulated to cover only 75% of protein (level 2) recommended by NRC. T3: control diet + 2.4 g undegradable methionine (Smartamine®)/day/kid (level 3). Feed intake, initial and monthly body weights were recorded. Blood samples were collected monthly and analyzed for metabolites and Co, Zn and Cu levels. Decreasing the dietary level of protein (T2) negatively affected (P<0.05) the total live weight gain, average daily gain and feed conversion ratio when compared with the control and T3 groups. Moreover, treatment, time and time × treatment caused a significant change on Co concentration in blood serum with higher value at the end of the experiment. Treatments had a significant effect (P<0.05) on blood serum cholesterol and protein levels. Undegradable methionine supplementation (T3) significantly increased longissimus dorsi weight, fat thickness and omental fat%. In conclusion, feeding Baladi kids below the NRC requirements of protein negatively affect the growth performance and feed efficiency. The recommended protein level by NRC for growing kids cover the requirements of growing black Baladi kids for maximum growth and productivity.</p></div></front></TEI><pmc article-type="research-article"><pmc-comment>The publisher of this article does not allow downloading of the full text in XML form.</pmc-comment>
