Ultrasound technology has come of age and is of great use to veterinarians and farmers alike for finding out which bulls are most virile so that the infertile ones can be segregated. Spring is preferred, and April is one of the best seasons for mating, and you need to ensure that you select the best and most fertile bulls to get the maximum benefits.
Spring season is preferred for breeding as the new grass available is of advantage to the new population. A period of two to three months is ideal for mating between bulls and cows. A typical full grown bull is capable of breeding up to 20- 30 cows on an average.
Fertility and pregnancy rates can multiply by five times if you have done a pre-screening and selected the most fertile bulls that are capable of mating with the cows. In a farmland with two or more bulls, the chances of contraception increase manifold with the help of ultrasound technology that helps in selecting the right bulls for mating.
For a majority of people, the source of income is dependent on the number of calves bred each year since they rely primarily on beef supplies. So it is essential to lay emphasis on bull selection and screen them for virility, semen quality and ability to mate with a cow that is in heat. In most countries, the entire program is done in close association with a certified veterinarian to ensure better results.
Criterion for mating:
The bulls need to be tested for fitness as during the winter season there is always the added risk of frostbite, the bull must also have good eyesight as it needs to select the right partner during mating. The cows and bulls selected should enable you to get one calf in a year at the very minimum.
Since there are two kinds of cattle: maternal ones which are good at producing milk and terminal breeds known for their beef, it is important to identify your purpose early and choose the right breed. However, some breeds offer both capabilities. The right amount of crossbreeding can help you to obtain a good breed in the long run. While some breeders aim at developing purebred lines, others go for commercial lines, and it is up to you to decide which breeding program you wish to follow. You can always purchase a purebred line for cross breeding with your animals later on as per your requirement.
A veterinarian can help you in conducting a breeding soundness exam that can help in screening bulls that are not fit for mating. While visual inspection can be of use in identifying and pre-selection and later on during pregnancy, it is unreliable and not full proof. Ultrasound technology is currently one of the best ways to determine any abnormalities or complications during pregnancy. The bull may look fit on visual selection but may not have the desired level of libido and may fail during actual mating which is why it’s important to keep a close eye on bulls when the cows are in heat.
However, bulls also need to be selected based on their sperm motility and sperm quality, i.e. how fast the sperms can swim and their size and other morphological features. But once the pregnancy sets in, the veterinarian and the producer need to keep a close eye on the developing fetus, and this can only be done correctly with the help of an ultrasound probe.
While there are many such tools available in the market, most of them are bulky and require you to take the animal to long distances but thanks to some portable ultrasound products that are now becoming the norm, a vet can visit you and perform a clinical examination on the animals on the spot. This results in more comfort for the animal and convenience for the owner as well.
