Correlação entre saúde materna e o desenvolvimento do cordeiro

Abstract

Against of the importance of a good sanity of breeding sheep for the getting of satisfactory production results, the accomplishment of this work had as objective to verify the correlation between the sanity of sheep of the Corriedale and Romney Marsh races in the peripartum with the development of lamb. The work was developed in a private property in Bagé city in the period of may until august of 2016, with evaluation of 17 breeding. In the experiment it was avaluated the ECC, stool samples were collected for the realize of OPG, and fortnightly, blood collections for blood counts tests and biochemical tests until the 30 days of lactation, and weighing of lambs at birth, at 15 and 30 days of age. The average age of the sheep was 3 years, being more than 70% presenting 6 to 8 teeth and 82,35% with equal or lower body condition to 2,5. The age of the sheep it wasn’t correlated with the weight of the lambs in the avaluated periods. The maternal body condition was significantly correlated with the weight of the lambs at 15 and 30 days of life as well as OPG was negatively correlated with lambs’ birth weight. Albumin concentrations at birth were significantly correlated with lamb weight at birth and at 15 days of age, while prepartum and postpartum cholesterol concentrations were significantly correlated with lamb weight at birth at 15 days and 30 days old. From the observed results, it can be concluded that maternal nutritional and sanitary levels can influence the development of lambs.
