Abstract

The present work was conducted to compare between Sudanese Fulani bulls Morphometric measurements and Western Baggara (Nyalawi ecotype) at different points of age (1 - 2 years, 3 - 4 years, 5 - 6 and above 7 years). A total of 368, (163 Sudanese Fulani and 205 Nyalawi) bulls were used. The Morphometric measurements studied were: live body weight (LBW), body length (BL), heart girth (HG), height at withers (HTW), hip height (HH) and rum width (RW). Relationship between live weight and external body measurements was determined by regression (r). The results revealed that based on live body weight, of Sudanese Fulani bulls at (1 - 2 years, 4 - 5 years and 6 - 7 years) were superior to Nyalawi bulls, but the different was not significant (P < 0.05). Also, all the correlation coefficients between live weight and the various body measurements of Sudanese Fulani bulls were significant (P < 0.01). A highly positive correlation coefficient was recorded between live weight and chest depth (r = 0.89, P < 0.01), while the lowest value was found between body weight and height at wither (r = 0.70, P < 0.01) for Sudanese Fulani bulls. Likewise, a high (r = 0.78, 0.56, 0.76 and 0.74) positive correlation between BW and HG were reported for Nyalawi bulls in all age groups under investigation. Moreover, body measurements of Sudanese Fulani were significantly (P < 0.05) higher than those of Nyalawi bulls at all ages The present findings showed the superiority of Sudanese Fulani bulls on Nyalawi bulls. The results suggest that body measurements and Morphometric measurements should be considered in the genetic improvements of this promised breed.
