RAMIREZ-BAUTISTA, Marco A. et al. Semen quality of hair sheep supplemented with Moringa oleifera (Moringaceae) and Trichanthera gigantea (Acanthaceae). Rev. mex. de cienc. pecuarias [online]. 2020, vol.11, n.2, pp.393-407. Epub 23-Oct-2020. ISSN 2448-6698. https://doi.org/10.22319/rmcp.v11i2.5010.
It was assessed the effect of the inclusion of Moringa oleifera Lam. and Trichanthera gigantea (Bonpl.) Nees in the diet of hair (Pelibuey) sheep on the quality of their semen. During 90 d, the diets of 15 sheep (24 kg ± 3.95) were divided into three treatments: T1: integral diet with 40 % of M. oleifera + Taiwan grass (Pennisetum purpureum Schumach.), T2: integral diet with 40 % of T. gigantea + Taiwan grass, and T3: 40 % commercial feed + Taiwan grass. The daily weight gain (DWG), carcass yield (CY), testicular development (DT) determined by the diameter (AE) and the scrotal circumference (SC) of these sheep were determined, and the volume, concentration, motility (CASA), viability (SYBR-14/IP), mitochondrial activity (J-C1) and acrosomal integrity (FITC-PSA) of their sperm samples were assessed. No differences were found (P>0.05) in the GDP and RC. Differences were found (P<0.05) in DT, T1 (AE= 48.84 ± 5.99 mm, CE=$9.29 ± 1.13 cm) and T3 (AE= 48.83 ± 4.34 mm, C = 26.62 ± 1.27 cm) exhibited higher values than T2 (44.57 ± 5.59 AE= mm, CE= 25.42 ± 1.50 cm); as for viability, T2 (62.90 ± 6.10 %) and T1 (54.00 ± 6.61 %) had higher percentages than T3 (24.45 ± 7.56 %); in motility, T1 (93.9 ± 2.1 %) and T2 (88.6 ± 1.9 %) had a higher percentage than T3 (71.9 ± 4.0 %). The inclusion of M. oleifera and T. gigantea in the diet allows to obtain a GDP, RC and DT similar to those of commercial feed and increases the number of viable sperm cells by more than 20 %; it also improves certain parameters of motility, thereby improving the reproductive potential of the stallions.
