Abstract:
The study compared live weight and linear body measurements of two breeds of cattle (White Fulani and Muturu Cattle) and regressed linear body measurements on live weight.
A total of eighty-six cattle of forty-three per a breed were reared at the cattle production unit of the Teaching and Research Farm, Akwa Ibom State University – Obio Akpa Campus, Nigeria in a semi intensive management system. Parameters measured were; live weight (LW), face length (FCL), head circumference (HC), ear length (EL), neck length(NL), neck circumference(NC), height at wither(HW), body length(BL), body circumference(BC), hind limb(HL), fore limb(FL), and tail length(TL). The data obtained were subjected to statistical analysis for morphometric traits and prediction was done through linear model regression method using SPSS statistical software package. Breed of cattle significantly (P>0.05) affected all linear body measurements and live weight exception of NL .Linear body Parameters of both breeds were compared. The mean live weight of White Fulani and Muturu were 251.28kg and 149.81kg, respectively. Means of FL, EL, NL, BL, HL, TL and BC, NC and HW of White Fulani were significantly (P<0.01) higher than Muturu breed but the HC of Muturu was significantly (P<0.01) higher than White Fulani breed. Muturu breed had higher R2 of 0.98 in BL and BC than White Fulani breed. In conclusion, White Fulani was considered a larger breed than Muturu cattle. Live weight can be accurately predicted from linear body measurements through BC and BL in both breeds.
