Sperms motility of Ongole Crossbreed (OC) Bull at various age

Abstract

The purpose of this study was to identify the effect of different ages on characteristics of sperms motility of Ongole Crossbreed (OC) bulls. The material used was 12 PO bulls aged 4–6 years old, distinguished into 2 age groups, namely 4-5 years old (6 heads) and 5–6 years old (6 heads). Collecting semen was done by using an electro ejaculator. Examination of motility (kinetic parameters) used SCA v. 2.1. The parameters measured include: progressive motility, motility, velocity curve linear (VCL), velocity straight linear (VSL), velocity average pathway (VAP), linearity (LIN), straightness (STR), wobble (WOB), amplitude lateral head (ALH), beat cross frequency (BCF) and hyperactivity (H) of sperms. Data were analyzed using a T-test (IBM SPSS 16). The results showed that the value of BCF in the 5–6 years old group was significantly higher (P<0.05) than the 4–5 years old group. The age of the bull affected the sperm’s kinetic parameters (BCF). The 5–6 years old group has a more regular pattern of sperms movement than the 4–5 years old group.
