For the Agr. Patricia Menchón, a professor at the Faculty of Agrarian Sciences of the National University of Mar del Plata – Balcarce Integrated Unit, it is possible to increase the productivity of herd herds in Argentina since “only 60% of the cows wean one calf per year “. According to the professional, this is possible from the application of process technologies that give more efficiency to the use of the resources already available in the productive system and, consequently, to improve reproductive rates of pregnancy, calving and weaning.
“One of the strategies, is to achieve the coupling of a period of maximum requirement, as is the service, with the maximum supply of forage,” said Menchón, and continued “this will depend on each system, it may be a climatic spring, or summer in those systems where there is greater predominance of the natural field “.
Likewise, the teacher considered the presence of the veterinarian to be very important for the review of the bulls before and after the service. Not only for the purpose of controlling venereal and reproductive diseases, but also to identify if there are animals whose reproductive capacity may be diminished for some reason.
On the other hand, he pointed out that rectal examination is another indispensable management tool, since it provides information on the physiological status of cows. This information allows ordering the rodeo, to allocate the necessary resources to each category according to their requirements.
“The choice of the moment of weaning is another important decision to make,” he emphasized the technique, and explained, “when weaning, the cow reduces the requirements of lactation to practically maintenance levels. In this way you can recover your body state to face the next productive cycle “.
Menchón also advised to plan food before and after delivery in order to ensure high pregnancy rates in the next service. “On a scale of 1 to 5, the cow is expected to be giving birth in a body condition of 3. On that scale which is from 1 to 9, at a value close to 5 of body condition.”
Another factor to take into account, explained the teacher, are fodder resources. “The application of input and process technologies, such as the implementation of strategic fertilization, the incorporation of pastures and greens of winter and / or summer, allow to modify the supply of forage. It is important to make a more efficient use of it through good management practices. In this way, a favorable impact on productivity levels can be achieved through the body condition of the bellies and the animal load. “
Menchón said that “it is very important the permanent training of field staff who are the day-to-day decision makers in breeding systems”, to continue, “nor should the state of the facilities in bovine breeding systems be neglected since , an adequate maintenance of the fences allows to organize stings according to available gauges in order to make an efficient use of the forage resources. The sleeve must be able to carry out the scraping of bulls and touch of the bellies. “
