Abstract :This work aims to assess the genetic diversity of local cattle breeds in Cameroon. For this purpose, biometric data were collected in six insert ignore into journalissuearticles values(6); localities of Mayo-Banyo, at random, on a sample of 321 adult Gudali variety Banyo zebus insert ignore into journalissuearticles values(234 cows and 87 bulls); aged 6 to 16 years old, with the body condition score varying from 2 to 4. Body measurements insert ignore into journalissuearticles values(cm); are presented as follows: Height at the withers insert ignore into journalissuearticles values(129.34 ± 0.50);, height at the sacrum insert ignore into journalissuearticles values(134.56 ± 0.37);, chest depth insert ignore into journalissuearticles values(67.37 ± 0.33);, head length insert ignore into journalissuearticles values(47.62 ± 0.42);, forehead length insert ignore into journalissuearticles values(20.33 ± 0.20);, horn length insert ignore into journalissuearticles values(34.45 ± 1.56);, ear length insert ignore into journalissuearticles values(22.66 ± 0.26);, body length insert ignore into journalissuearticles values(187.74 ± 2.45);, trunk length insert ignore into journalissuearticles values(130.5 ± 1.27);, scapulo-ischial length insert ignore into journalissuearticles values(137.88 ± 1.33);, pelvic length insert ignore into journalissuearticles values(42.87 ± 0.31);, tail length insert ignore into journalissuearticles values(100.52 ± 0.88);, pelvis width insert ignore into journalissuearticles values(38.31 ± 0.32);, face width insert ignore into journalissuearticles values(17.61 ± 0.27);, muzzle circumference insert ignore into journalissuearticles values(44.60 ± 0.44);, chest circumference insert ignore into journalissuearticles values(167.81 ± 1.46);, barrel circumference insert ignore into journalissuearticles values(18.60 ± 0.16);, hock circumference insert ignore into journalissuearticles values(38.72 ± 0.35);, hump circumference insert ignore into journalissuearticles values(73.37 ± 1.92); and live weight insert ignore into journalissuearticles values(350.24 ± 8.70);. The main biometric indices are: The massivity index insert ignore into journalissuearticles values(2.69 ± 0.06 kg / cm);, proportionality insert ignore into journalissuearticles values(94.42 ± 1.06);, cephalic insert ignore into journalissuearticles values(37.13 ± 0.55);, body profile insert ignore into journalissuearticles values(0.69 ± 0.01);, surface insert ignore into journalissuearticles values(1.79 ± 0.02m2);, format insert ignore into journalissuearticles values(1.44 ± 0.01);, scapulo-ischial insert ignore into journalissuearticles values(1.06 ± 0.01);, typist-thoracic insert ignore into journalissuearticles values(0.11 ± 0.00);, thoracic development insert ignore into journalissuearticles values(0.77 ± 0.00);, framing insert ignore into journalissuearticles values(0.14 ± 0.00);. Bulls and other cattle reared in controlled systems presented a large format. The discriminant factor analysis made it possible to detect three morphometric types identifiable with two phenotypes.
