“…The females also recorded the highest correlation between body weight and chest girth (r = 0.94). [16] suggested that chest girth could be used as a reliable predictor of body weight in most livestock species. The positive and significant correlations reported in this study agrees with the findings of [12,17]; in Bunaji and Rahaji breeds of cattle.…”

Stepwise multiple regression technique was used to predict body weight from linear body measurements in the savannah muturu cattle (Bos brachyceros). Sexual dimorphism was a significant (P˂0.05) source of variation for body weight (BW), ear length (EL), body length (BL), chest girth (CG), horn length (HL) and height at withers, with higher values reported for the males. Correlation coefficients between body weight and linear body measurements and within linear body measurements were all positive and significant (P˂0.01) irrespective of the sex of the cattle. The regression technique established highly reliable equations for predicting body weight from chest girth, body length and horn length. The best model for predicting body weight was BW = -72.908 + 1.738 CG + 3.511 HL. Information derived from this study may find application in selection for improvement of traits of economic importance in the muturu cattle.

“…Hermes (1989) reported that high level of inbreeding causes embryonic mortality as a result of genetic mutations and negatively affected hatchability but the specific lethal genes have not yet been recorded in ostriches. Hatchability to a large extent is a derivative of fertility and the presence of major genes and strain/breed differences that affect embryonic livability (Peters et al, 2005). Geneticists always suggest that the performance of individuals at a point is a function of genotype and environment interaction (Peter, 2000).…”

Intensification of ostrich farming revealed that egg hatchability was remarkably lower than the wild. This review considers the factors leading to, as pertaining to the ostrich, egg and incubator. Ostrich genotype, age, season and congenital problems affect clutch and egg sizes and egg quality- fertility to lead a successful hatch. Egg treatment prior incubation can later reduce hatchability, affected by storage conditions and duration. Most detrimental factors lie in the incubator and hatcher management. Egg correct positioning and turning in the appropriate incubator humidity and temperature are likely to yield high hatch. Variability in egg size, shell quality, pore sizes and numbers govern the water loss and exchange of gases. The hatcher management is important when chicks need intervention. Dead-in-shell embryos, early or late were likely to be affected by all of the above factors plus egg microbial contamination or be merely nutritional.Int J Appl Sci Biotechnol, Vol 3(4): 566-578
