Abstract

Evaluation of the Spermate Quality of Cattle Players Through the use of Conventional Seminal Evaluation Systems and Casa System

Highlights

The analysis of seminal quality represents a valuable tool to evaluate the fertilizing potential of males of different species and complements the physical assessment of the animal (Montes, Torres, Rugeles, Almanza, & Guimarães, 2012)
Seminal quality is studied, which is determined by the comparison of the parameters obtained with the values that are considered normal for an adult reproductive bull. (Vera Muñoz, 2008)
When evaluating the individual motility percentage (MI), the Jersey race presented higher MI with an average 86.81% while for Holstein and Brown Swiss their percentages are lower 80.68% and 73.41% respectively; values that are lower than those obtained by (Moncayo, 2016) in which it varies between 85% and 96% for the Holstein and Brown Swiss races; in this sense Rubio et al (2007) independently of the bovine race obtain MI of 62.91%; (Vera Muñoz, 2008) qualifies ejaculates with MI above 80% as very good corresponding to the values obtained for Holstein and Jersey and a Good rating for ejaculates with MI of 70 - 80% corresponding to Brown Swiss

Summary

Introduction

The analysis of seminal quality represents a valuable tool to evaluate the fertilizing potential of males of different species and complements the physical assessment of the animal (Montes, Torres, Rugeles, Almanza, & Guimarães, 2012). Seminal quality is studied, which is determined by the comparison of the parameters obtained with the values that are considered normal for an adult reproductive bull. Many researchers have devoted much work and resources to try to eliminate the subjectivity inherent in the microscopic evaluation of semen quality. Fruit of these investigations was the development of computerized systems for the analysis of sperm motility. Specialists in animal reproduction are trying to design the "ideal seminal analysis", which adequately assess and predict the fertility of a seminal sample in the most accurate way possible. The analysis of ideal semen would be one that in a simple and effective way would allow to know in a predictive way the fecundating capacity of an ejaculate. (Mellisho, 2010)
