Contribuição da ultrassonografia na avaliação andrológica de bovinos Nelore

Abstract: Ultrasonography was auxiliary methods of breeding soundness evaluation. Different cuts testicles and urinary glands, analyzing image, quantifying the gray scale and mensuared biometric measurements and testicular form. 111 Nellore steers were examinated from 9 to 15 months. It was divided into 3 groups: Traditional Nelore (NeT); Selection (Nellore); Control (NeC). Using the device Pie Medical Scanner 200C, attached to a linear transducer of 8 MHz, with the help of software "Echo Image Viewer" (EIV) and is quoted grayscale (EC) of the testicles. The average was 30.43; 30.51 and 31.44% for NeT; Nellore; NeC, respectively. The JV plans scans average in the period 9-15 months was 33.09 and 28.18% in the transverse and frontal planes. There were no differences of CE to the left testicle and right. Pubertal animals and im-pubescent had the average of different CE, and there was significant difference in the EC diferent ages, in the testicle and the bladder glands. The percentage is different, but the testes were 61.39; 32.12; 6.07, 0.30 and 0% for long oval shapes, moderately long oval spherical and spherical, respectively. The difference in testicular ages 9, 13 and 15 months was 5.15, 3.54 and 2.64% respectively.
