Semen quality parameters of the Tanzanian Horasi chicken ecotype

Predicting potential fertility and eventual egg hatchability in chickens can be done by evaluating the quality of semen. This study's objective was to describe semen characteristics three different age groups Horasi chicken ecotype cocks (24-32, 28-36, 32-40 weeks). From 20 cocks; 6 (24-32 weeks), (28-36 8 (32-40 weeks) over course four weeks (5-29th Dec 2022), 80 samples total were taken. Sperm harvested from using abdominal massage technique. The amount semen, pH, sperm motility, concentration, live spermatozoa percentage, with normal morphology percentage all measured. Between groups, volume, spermatozoa, ranged 0.52 ± 0.03mL 0.68 0.03mL, 7.24 0.01 7.31 0.01, 75.16 0.91% 76.67 1.07%, 4.31 2.27 4.56 3.34 × 109 cells/mL, 90.00 0.55% 91.04 0.85% 87.78 0.51 89.71 0.68% respectively. Only differences ejaculate volume between significant at p<0.05. parameters had extremely low moderate Pearson correlation coefficients, values ranging - 0.22 0.38 concentration morphologically cells that are alive ecotype's within range, notwithstanding possibility individual may differ one another some as a result environmental influences. Using artificial insemination, breeding programs therefore exploit increase productivity indigenous chickens.
