GUSMAO FILHO, J.D.; TEODORO, S.M.; CHAVES, M.A.  and  OLIVEIRA, S.S.. Factorial analysis of morphometric measurements in Santa Inês like ovines. Arch. zootec. [online]. 2009, vol.58, n.222, pp.289-292. ISSN 1885-4494.

This study was made with the objective of realize a morphological evaluation of Santa Inês like ovines using the factorial analysis. Twenty two sheeps were used: 12 ewes and 10 rams. The measurements were taken every fifteen days, after the animals reached the average live weight of 26.8 ± 5.2 kg and were 4.5 months old. The following variables were measured: withers height, hindquarters height, back height; body length, hindquarters length, back length, scrotum length; hindquarters width, breast width; scrotal perimeter and thoracic perimeter. The factorial analysis was used in order to verify the existence of main relationships among morphometric measurements. Five factors were found and their respective communalities. The factorial analysis was efficient to group the linear measurements made ease the visualization of the main relationships among morphological measurements. These results can be of great importance in the determination of body attributes of sheep in both reproduction and meat production.
