“…There are few papers that have reported on phenotypic and genotypic parameters of the indigenous Guinea fowl [4]. The present paper complements a similar one on co (variance) components and heritability of traits of the Guinea fowl presented by [5]. The objective of this work was to estimate phenotypic and genotypic correlations among traits of the Guinea fowl.…”

This study aimed at estimating genetic and phenotypic correlations among traits in local Guinea fowl in Ghana. Animal farm of Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development Mampong-Ashanti campus was where the study took place, from 2015 to 2018. Data for the experiment was obtained from keets made up of 300 males and 300 females. Parents of the keets consisted of 110 dams and 22 sires. Arithmetic method and Pearson’s product moment correlation were used for the estimates. In male Guinea fowl, the values of genetic correlations among growth characteristics ranged from -0.63 to 0.93. Between growth and other characteristics, estimates of genetic correlation ranged from 0.29 to 0.97, -0.67 to 0.43, -0.62 and 0.94 respectively. Values of phenotypic correlations among growth parameters were between -0.32 and 0.49. Range of figures of phenotypic correlations recorded between growth characteristics and survival, docility, and dressing percentage were between -0.28 and 0.28, -0.46 and 0.18, and -0.41 and 0.36 correspondently. In female Guinea fowl on the other hand, range of genetic correlations among growth traits was between -0.80 and 0.95. Range of figures of genetic correlation between growth traits and survival, docility, dressing percentage and reproductive characteristics of were from -0.47 to 0.9, -0.52 to 0.58, -0.58 to 0.82 and -0.59 to 0.9 respectively. The values of phenotypic correlations among growth characteristics fell between -0.39 and 0.46. Phenotypic correlations recorded between growth traits and survival, docility, dressing percentage and reproductive characteristics were from -0.26 to 0.47, -0.47 to 0.19, -0.35 to0.47 and -0.33 to 0.47 respectively. Values of genetic correlations higher than one (1) among some traits in male Guinea fowl were recorded. To conclude, discoveries of this study are in general agreement of what pertains to Guinea fowl and other farm livestock species.

“…Ebegbulem and Okon (2018) reported, in Nigerian Guinea fowl, that heritability for body weight ranged from 0.40 to 0.81, while repeatability estimates were at a range of 0.20 to 0.40 at 8 weeks and 12 weeks of age. In the same way, Doudu et al (2020) conducted a study to estimate heritability of body weight and body weight gain in indigenous Guinea fowls and found that heritability values for body weight decreased with the age of the birds. The heritability estimates of body weight gain on the other hand did not follow a particular trend with respect to age in both sexes.…”

Background. Guinea fowl (Numida meleagris) is used as an alternative for the production of meat with high nutritional value; however, there are several factors that affect their productive performance. Objective. Review the main factors that affect the productive performance of the guinea fowl described in the worldwide literature. Methodology. A bibliographic review in the databases of Scopus, NCBI, Springer, Science direct, Google Scholar, Redalyc, and other repositories was carried out. The keywords for the search were: Guinea fowl, Numida meleagris, productive performance and body weight gain. Results. The production system is one of the main factors that affect the productive performance of the Guinea fowl. Birds raised in semi-intensive conditions have better weight gains compared to those that are kept under an extensive system. Mortality in the extensive system increases due to poor or no disease prevention practices and natural predators. The increase in population density under intensive management conditions negatively affects the performance and welfare of Guinea fowl. Ignorance of the energy and protein requirements causes a deficient productive performance in weight gains. Genetic factors also play a role; in Africa local varieties that have not been genetically improved are bred in extensive systems obtaining low yields, compared to developing countries. Birds hatch from large eggs with shorter storage periods had better growth performance. Implications. There is limited information on the main aspects related to the raising of the Guinea fowl, including the factors that affect its productive performance. Ignorance of the productive parameters favors the displacement of Guinea fowl production by other poultry species, such as chicken. Conclusions. Breeding the Guinea fowl as an alternative for meat and egg production must be accompanied by the disclosure of productive parameters to improve their production performance.
