Abstract
The current study was conducted to investigate the effect of addition of black Maca (Lepidium meyenii) roots powder on luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, thyroxine and growth hormone (GH) concentrations, and some productive traits like body weight and body condition score (BCS) in Awassi lambs. In this study, 32 Awassi male lambs 8-month-olds were divided randomly into two treatment groups (16 lambs each): first group lambs were fed basal ration plus 1g/head/day of black Maca roots powder (T1), while the second group lambs were fed basal ration only (T2), the duration of study was two months. Results revealed that LH, FSH, testosterone and GH concentrations were higher (P ≤ 0.05) in lambs fed black Maca roots powder than those fed basal ration only. Furthermore, body weight, and body condition score (BCS) in lambs fed black Maca roots powder were higher (P ≤ 0.05) than in those fed basal ration only. In conclusion, addition of black Maca roots powder improved reproductive hormone concentrations as well as growth hormone concentrations and enhanced body weight in Awassi male lambs.
