T evaluation of bulls for breeding soundness is an effective and reliable way to identify bulls that are potentially poor breeders. This management technique can be used to greatest advantage if culling occurs before bulls are turned out with females. Also, the evaluation is an important means available to the producer for predicting bulls with satisfactory to excellent potential. This informat...

rtificial insemination (AI) has become an increasingly common practice in the swine industry, and the value of boars for both AI and natural mating has also increased. It is therefore important to promote routine breeding soundness examinations (BSEs) on boars, which can help to identify poor or questionable breeders before they affect herd fertility and/or destroy an AI stud’s reputation. It w...

The capability of bulls to distribute their genetics is dependant upon their fertility, whether they are used for natural breeding or A.I. In turn, herd reproductive performance has been shown to have a greater impact on economic returns than either growth rate or product quality (Wiltbank 1994). Here, chute-side math indicates it takes approximately 5 generations (15 years) using bulls of 10% ...

Background: Breeding soundness evaluation (BSE) is the primary assessment for determining reproductive potential of male animals. This method, however, cannot be used to evaluate semen frequently or to predict future semen quality. Computerized analysis of ultrasonographic images provides information on histophysiological changes in male reproductive organs.We hypothesized that: 1. semen parame...

Pregnancy rate evaluation of the profitability of any beef cattle operations, the profit or loss is one of the most important factors determining. Emphasis and focus on adequate nutrition and reproductive management beef cattle herd, but, unfortunately, most placed little emphasis on beef cattle operations kept. However, each beef cattle breeding season during a typical cow-calf operation in 15...
