• Abstract:

  The objective was to evaluate the use of amino acids that promote live weight gain, body condition (BC) and hematological parameters of Dorper lambs. The study was carried out during the months of May - August 2023 in northern Mexico (25° LN). 40 lambs with an average age of 3 months, homogeneous in terms of live weight (LW; 16.02 ± 2.44 kg) and body condition (BC; 1.7 ±.2) were used and were divided into two groups (n=20 each). A first group (Treated) was administered 10 mg of promoter amino acids. While a second group (Control) was given 0.5 of physiological saline solution as a placebo effect. The treatment was applied in a single dose. The PV and WC were recorded, and the levels of white blood cells (WBC) and red blood cells (RBC) were determined at the beginning and end of the study period. The general average of final PV (26.0 ± 6.0) and WC (2.4 ± 0.1) showed no difference (P>0.05), as did GB (113.8 ± 22.0) and GR (3.53 ± 1.0). The results show that there was no effect on weight gain, body condition, and white and red blood cell levels. In conclusion, administration of a single dose of 10 mg of amino acids did not promote weight gain, body condition, and white and red blood cell levels in Dorper lambs.
