Abstract
This study was carried out in Funtua, Kastina State. A total of 119 Eggs of the French broiler guinea fowl were sourced at Songhai Agricultural center Funtua, Kastina State. The eggs were measured for egg linear measurements and egg length and egg width. Data obtained was subjected to statistical package for analysis [1]. The correlations between body weight and body linear measurements were determined using pearsons product moment correlation coefficient (r). Phenotypic correlation between egg weight and egg linear measurements was also determined. Egg weight had positive and significant (P<0.05) correlation with egg length (0.275) and egg width (0.496). The correlation between egg shell index was negative (-0.058). The result shows that Egg weight can be improved by selection for egg length and width French broiler guinea fowl populations. Meat and meat products are major sources of high-quality protein and their amino acid composition usually compensates for deficiencies in the staple foods. Production of family poultry is regarded as an alternative way to alleviate poverty and support to ensure food security for socio-economically disadvantaged rural households (Branckaert and Gue’ye, 1999). In third world countries, the guinea fowl production could become much more valuable than it is today (Siana, 2005; Fajmilehin, 2010; Moreki, 2010). It thrives under semi intensive and extensive conditions, forages well, and requires little attention from the farmer (Dahauda, 2007). The guinea fowl also retains many of its wild ancestor’s characteristics, they are hardy and resistant to environmental challenges, produces well in cool and hot conditions (Dahauda, 2007). Compared to chickens, guinea fowls are economically more suitable to tropical regions because of their adaptations to traditional breeding systems (Dahauda, 2007). The potential of the Guinea fowl to increase meat and egg production among low income farmers requires greater attention (Rhissa and Bleich, 2009). Guinea fowls are widely known in Africa (Solomon, 2012) and occur in few areas in Asia and Latin America. Strains newly created for egg and meat production in Europe, notably French broiler and layer guinea fowls show excellent characteristics for industrial scale production [2]. Guinea fowl production as a meat bird has proven to be a viable and profitable enterprise, thus providing opportunity for commercial production in many parts of the globe [2]. A survey indicated that interest in guinea fowl as an alternative poultry and specialty meat bird in the United States appears to be increasing. The French variety of guinea fowl is raised primarily for meat [2]. Although their growth rate is slower than that of broiler chickens, the carcass yield of male and female guinea broilers at 12 weeks of age is about 76.8 and 76.9%, respectively (Hughes and Jones, 1980). In recent studies evaluating the optimum Crude Protein (CP) and Metabolic Energy (ME) for the French guinea fowl broiler, Nahashon (2005) reported carcass yields of about 70% at 8 weeks of age. Genetic and phenotypic correlations are useful in prediction of direct and indirect responses to selection and determination of optimum weight and expected correlated response to selection [3].
