Evaluación morfológica y la calidad seminal de verracos criollos de la parroquia Palmira- Chimborazo.

Abstract

The objective of this work was to determine the morphological characteristics and semen quality of the creole boars of Palmira Parish, Guamote Canton for the selection of stallions for reproductive purposes. We used 10 pigs of the category boars of 1 year of age, descriptive statistics (means, standard deviation, maximum and minimum values). Live weight and 13 zoometric measurements (face width, face length, head length, ear width, ear length, live weight, height at withers, body length, dorso-sternal diameter, rump width, rump length, thoracic circumference, posterior cane perimeter, anterior cane perimeter and bicostal diameter) were evaluated to determine morphological characteristics. For the evaluation of seminal quality, volume, odor, color, pH, sperm concentration, mass motility, individual motility, morphoanomalias, sperm viability of boar semen was measured. The ejaculate of the Creole boars of the Palmira Parish presented an average volume of 189.11 ml, pH 6.71, mass motility 3.55; individual motility 60.75 %, concentration, sp/ml 5.73e 06, morpho-anomalies 12.33 % and viability 89.75 %. It was concluded that the best Creole boar of the Palmira Parish is pig No. 6. It was recommended to carry out studies of other factors such as age, nutritional level, physiological state, which may intervene in the variables of the microscopic characteristics of the semen evaluation.
