Alternativa para la detección de celos en el ganado bovino mediante el potencial uso de caninos (monografía).

Abstract

Cows go into heat every 21 days and it is a period of sexual receptivity for the animal, this stage of heat lasts around 12 hours from the moment in which the estrus begins with an ovulation that lasts around 25 to 36 hours after the start of estrus, this is important in order to achieve reproductive planning and thus achieve economic efficiency in livestock businesses. We analyzed different studies of different diagnostic methods for the detection of bovine heat (visual, watchful bulls, patches, paint on the base of the tail and pedometers) and we reached the conclusion that the use of a single diagnostic method does not cover 100% of efficiency and, on the contrary, the use of different diagnostic methods in a single farm increases this percentage. It is known that the dog has a defined ability to detect substances through its smell and that some breeds (Belgian Shepherd Malinois, Labrador, German Shepherd, Dutch Shepherd, Golden Retriever) can be trained to identify different substances (cancer, other animals, microorganisms, corrosion, hallucinogenic substances, body fluids, explosives) in different scenarios. There are studies carried out since 1978, in which the efficiency of the use of canines as a method for the diagnosis of heat in cattle has been observed, which show good results and with which it is proposed to complement the diagnostic methods used in the present each livestock farm.
