摘要

There is a need to determine the effects of unconventional feed resources on the blood and reproductive parameters of animals receiving them. A total of 50 Large White Boars aged 7–8 months old were used to evaluate the effects of Aspilia africana (AA) leaf meal on the hematologic, serum biochemical, selected hormone profile, semen, and libido parameters. The pigs were grouped into five experimental groups in a completely randomized design (CRD), one control diet and four treatment diets: AA2.5, AA5.0, AA7.5, and AA10.0, containing 2.5, 5.0, 7.5, and 10.0% AA leaf meal, respectively. For the hematologic parameters, AA5.0 and AA7.5 significantly (P < 0.05) increased hemoglobin (Hb) and red blood cell (RBC), while AA5.0, AA7.5, and AA10.0 significantly (P < 0.05) increased packed cell volume (PCV), white blood cell (WBC), lymphocyte, and neutrophil counts. Dose-dependent increases were recorded for the platelets, while the mean corpuscular hemoglobin concentration (MCHC) was significantly (P < 0.05) lower in AA10.0 than the control. For serum biochemical parameters, total protein (TP) and globulin were higher (P < 0.05) in pigs on AA5.0, AA7.5, and AA10.0, while cholesterol was significantly (P < 0.05) lower in pigs on AA5.0, AA7.5, and AA10.0. Serum levels of testosterone (T), estradiol (E2), and triiodothyronine (T3) were higher (P < 0.05) in pigs on AA5.0, AA7.5, and AA10.0. Semen and libido parameters recorded higher (P < 0.05) total sperm count, sperm concentration, live sperm proportion, and libido score in pigs on AA5.0, AA7.5, and AA10.0, while progressive sperm motility was higher (P < 0.05) in AA2.5, AA5.0, and AA7.5 pigs than the control and AA10.0 pigs. Percentage abnormal sperm was higher (P < 0.05) in pigs on AA7.5 and AA10.0, while reaction time was lower (P < 0.05) in pigs on AA5.0, AA7.5, and AA10.0. The results of this study reveal that AA leaf meal can be utilized in diets of male pigs to improve protein synthesis, cellular immunity, and semen and Libido characteristics but should not exceed a 5% inclusion level for breeder boars.
