چکیده

Guinea fowls represent an important animal genetic resource for food security in Nigeria. This study was conducted to investigate sexual dimorphism and the effect of location on morphometric traits guinea fowls, obtain fewer uncorrelated orthogonal variables (principal components) from body linear measurements fowl, homogeneous groups a heterogeneous set adult fowl predict live weight . A total one thousand seventeen(1,017) varieties aged between 28 39 weeks (774 pearls; 64 lavenders;151 black white varieties) consisting 457 males 560 females were randomly selected rural farmers markets two Local Government Areas (LGAs) each Osun Oyo States South-Western Data collected weight, helmet height, wattle length, thigh circumference, shank neck wing length using standard procedures. analyzed GLM, REG, PRINCOM CLUSTER procedures SAS.

Histomorphology of Thymus Gland in Guinea Fowl (Numida meleagris)

The thymus gland is a lymphoid tissue derived from III and IV pharyngeal pouches. It is the source of stem cells that migrate to other lymphoid organs and participate in immune reactions (Kent, 1978). The thymus gland is regarded immunologically as a primary or central lymphoid organ and its presence is essential for the development of peripheral lymphoid tissues and their associated adaptive i...

Sexing in guinea fowls (Numida meleagris).

Despite the potentials and contributions of guinea fowls to economic and social life in Ghana, accurate sex identification in these birds is still a major problem. Three hundred and sixty guinea fowls (180 birds per sex) were used in determining a more accurate and farmer friendly sexing technique. The sexing methods explored were vent, biometric, and molecular techniques. Vent sexing was accom...

Histogenesis of the Oesophagus of Guinea Fowl (Numida meleagris) at Prehatch and Posthatch

The histogenesis of the primordial oesophagus was studied to determine the period in which the tunics of the oesophagus developed and became functional in the helmeted guinea fowl (Numida meleagris). Eighteen embryos and nine keets were studied at prehatch and posthatch, respectively. Simple columnar epithelium surrounded by mesenchymal cells was obvious at the 8th day of embryonic development....

A natural outbreak of Newcastle disease in guinea-fowl (Numida meleagris galeata) in Nigeria.

A natural outbreak of Newcastle disease (ND) was reported in a flock of guinea-fowl in Nigeria, affecting 1,029 birds of which 250 (24.3%) died. Paralysis of the legs and wings, coughing, sneezing, white diarrhoea and complete cessation of egg production were observed. Serum samples collected at the onset and during the course of the disease had high ND antibody titres. ND virus was isolated fr...

Effects of load carrying on metabolic cost and hindlimb muscle dynamics in guinea fowl (Numida meleagris).

The goal of this study was to test whether the contractile patterns of two major hindlimb extensors of guinea fowl are altered by load-carrying exercise. We hypothesized that changes in contractile pattern, specifically a decrease in muscle shortening velocity or enhanced stretch activation, would result in a reduction in locomotor energy cost relative to the load carried. We also anticipated t...
