- Abstract
The leaves of the tropical tree Leucaena leucocephala are often used as a livestock feed input. However, they contain mimosine, an antinutritional factor that can negatively affect animal physical parameters. An evaluation was done of testicular characteristics in pubescent ram that had consumed fresh L. leucocephala leaves. Experimental animals were 20, 5-month-old male Creole ram (average weight = 24.4 ± 3.21 kg) housed in individual pens. During the 120 d experimental period 10 males were fed a 0 % Leucaena diet (control) and another 10 were fed a diet including 25 % fresh L. leucocephala (Leucaena). Real leucocephala intake was determined by the difference between the quantity that was offered, and the quantity was rejected. For the determination of testosterone and mimosine in blood, an ELISA kit and HPLC were used respectively. Scrotal circumference measurements were taken, and testicular volume was estimated. A histological study was carried out; to determine the integrity of the testicular parenchyma testicular. The 40 % of male’s intake L. leucocephala presented interstitial edema and tubular atrophy in the testicular parenchyma of pubescent ram. Scrotal circumference and testicular volume were not affected; however, edema and atrophy of the seminiferous tubules were found in animals that intake Leucaena leucocephala.
