Bodyweight is one of most important economical traits in dairy cattle and is affected by different environmental factors. One of genetic factors that affects cow conformation traits, is the breed effect. The aim in this study was to determine how breed of cattle affect morphological traits in cattle. In this study, bodyweight BW , seven body traits Body weight, BW Body condition score, BCS stature, ST chest width, CW body depth, BD heart girth, HG rump width, RW , five udder traits chest ligament, CL rear udder height, RUH rear udder width, RUW udder clearance, UC teat length, TL were analyzed. Analysis of variance procedures of R 3.0.3 statistical software was used to test the breed and significance difference in means were separated using Tukey test. In hot climate of Kwara State, the effects of genotype significantly influence body weight, body depth, heart girth and rear udder depth. The crosses of Holstein Friesian and Jersey were more superior to its crossbred’s cows. It is concluded that Holstein and Jersey crosses should be use for genetic improvement programs targeted at improving meat and milk production. Omoniwa D. O | Okeke R. O | Adeniyi, O. O | Oladipo M.

ABSTRACT
Bodyweight is one of most important economical traits in dairy cattle
and is affected by different environmental factors. One of genetic
factors that affects cow conformation traits, is the breed effect. The
aim in this study was to determine how breed of cattle affect
morphological traits in cattle. In this study, bodyweight (BW), seven
body traits (Body weight, BW; Body condition score, BCS; stature,
ST; chest width, CW; body depth, BD; heart girth, HG; rump width,
RW), five udder traits (chest ligament, CL; rear udder height, RUH;
rear udder width, RUW; udder clearance, UC; teat length, TL) were
analyzed. Analysis of variance procedures of R 3.0.3 statistical
software was used to test the breed and significance difference in
means were separated using Tukey test. In hot climate of Kwara
State, the effects of genotype significantly influence body weight,
body depth, heart girth and rear udder depth. The crosses of Holstein
Friesian and Jersey were more superior to i
