Abstract

Guinea fowl hens were inseminated weekly once with two doses of spermatozoa (75 million and 100 million) in two different diluents, Beltsville poultry semen extender (BPSE), and Instruments for Veterinary Medicine (IMV), each with and without pre-insemination vaginal douching. Per cent fertility,...

AbstractFull Text

A comparison has been made between natural mating (NM) and artificial insemination (AI) in fast feathering Huainan partridge chickens. A total number of 360 fast feathering Huainan partridge hens and 40 roosters were randomly divided into two equal groups. For NM, 4 mating cages were maintained...

Abstract

This article gives an overview of the farming, breeding and performance of layers in Ghana. The inability of broiler producers to compete with imported meat due to lack of import limitations in the country, which in turn results to the predominance of table egg producers, is discussed. Moreover,...

Abstract

The relationships between age of hens, number of laid eggs, egg weight on one hand and fertility and hatchability on the other were analysed during two periods of individual pedigree hatching. Altogether 1 369 hens originated from 9 selected initial laying lines of Bar Plymouth Rock (BPR) (3...

Abstract

Among the factors to consider in the technology of artificial insemination in hens., the insemination frequency constitutes an important aspect, since it contributes to achieve a profitable rising. The aim of this work was to evaluate the fertility and incubability of eggs coming from reproductive...

Abstract

Strategies that would increase eggshell quality could be of considerable value to egg producers. This research demonstrated the effective use of fibroblast growth factor 23 (FGF-23) peptide vaccines to increase eggshell quality of Single Comb White Leghorn laying hens (from 69 to 72 wk of age)....

Abstract

During the artificial insemination process, turkey breeder hens may become infected with influenza virus acquired from humans. The virus has been shown, through experimental infection, to localize in the reproductive tract, with limited dissemination in other tissues. A limited number of hens were...

AbstractFull Text

The present study was conducted at Poultry Research Institute (PRI), Rawalpindi, to evaluate productive performance of the four successive generations (P1, P2, P3 and P4) evolved after selective breeding for first laying cycle (52 weeks egg production) in comparison to their parents (P0). For this...

Abstract

A hypothesis was tested that providing the breeder hens with exogenous thyroxine (T4) would help their offspring to better survive the ascites-inducing condition during the growing period. In total, 132 broiler breeder hens were randomly assigned to one of 3 treatments: control (CON), hypothyroid...

Abstract

Two experiments were conducted to examine the effects of broiler breeder dietary grain source and cage density on maternal antibody (MatAb) transfer to progeny in 2 genetic strains (A and B). Broiler breeders were assigned to 16 litter floor pens and fed either corn- or wheat-based diets. Breeders...
