A. P. de  aEvaluation of sheep breeds for early growth in tropical north-east Brazil.  c1982  aAbstract: Three breeds of sheep, Brazilian Somali, Morada Nova and Santa Inês which are indigenous to hot tropical semi-arid northeast Brazil were studied for their early growth. There were large breed differences in size at birth, at the 86th day and at 6 months. The Santa Inês was the largest and the Brazilian Somali the smallest. The type of birth (single vs. multiple) had a profound effect on weight at virtually ail stages of growth which was similar for male and female lambs. Sex effects tended to become significant at around the 86th day, female lambs slightly outweighing males but marked sex differences appeared around 6 months when males outweighed females. The 7-day variation in age of lambs when the weights were taken around the 15th day had a marked effect on weight and correction for age would be necessary in future studies. However, the 7-day variation in age around the 86th day and thereafter did not affect the weights. The birth weight and weights at the 15th, 86th and 112 days and at 6 months were significantly correlated.  aAnimal genetics  aBirth weight  aBody weight  aBrazil  asheep  aEspécie nativa  aOvino  aPeso ao nascer  aBrasil  aFemale animals  aNative species  aNordeste  aNortheast  aPeso corporal  aRaça nativa1 aSIMPLICIO, A.
