Evaluation of the causes of anestrus in dairy cattle herds in Camaguey
Abstract
To determine the reproductive, metabolic, health and food status and evaluate the physical-productive status of the farms of two dairy cattle herds with a high incidence of anestric females belonging to a livestock company in the province of Camagüey, Cuba was performed on all animals the clinical-gynecological examination, the evaluation of the body condition, the determination of the live weight, a parasitological analysis and the evaluation of the metabolic state were used four groups of females: pregnant women in the last third (> 7½ months), recentins, between 15 and 20 days and 60 days of births and females with more than 60 days postpartum without being inseminated (empty), finally the evaluation of the availability of pastures and the consumption of dry matter in each of the herds was carried out . The data obtained were processed using the generalized linear model. The clinical-gynecological diagnosis showed problems with estrous cyclicity related to deficiencies in the detection of heat, high parasitic infestation (Fasciola hepatica), food problems and metabolic disorders (energy metabolism, protein, immune deficit, hypocalcemia and hypophosphoremia). The reproductive behavior of the herds and their state of health were related to the physical-productive state of the farms. It is recommended to improve the productive physical state of the farms to ensure an adequate forage balance and reproductive management in the herds based on the body condition and other health indicators of the female.
