“…The increase in body weight for all the chick genotypes studied from day-old to 20 weeks can be explained from the fact that animal growth involves increase in size and changes in functional capabilities of the various tissues and organs of animals from conception through maturity. This observation is consistent with the reports of Peters et al (2005), Adebambo et al (2006) and Adedeji et al (2008). According to Gous (1997), growth is normally accompanied by an orderly sequence of maturational changes and involves accretion of protein and increase in length and size, not just an increase in body weight.…”

Six-hundred-and-seven-day-old chicks were generated from Nigerian local chickens consisting of three genotypes (Normal-feathered; Frizzled-feathered; Naked neck) and an exotic broiler breeder (Anak Titan) to evaluate growth performance for possible meat-type chicken development. Growth parameters measured were body weight, breast girth and keel length on weekly basis for 20 weeks. Effects of sire, dam and chick genotypes were significant (P<0.001) on growth traits. At week 20, chickens sired by the Anak Titan weighed 1,614.82 g followed by Normal-feathered local chickens with body weight of 1,211.32 g. Progenies of Anak Titan and Naked neck dams weighed 1,761.96 and 1,292.80 g at week 20, respectively. Among purebreds, Anak Titan weighed 35.05 g at day-old and had heaviest body weight of 2,360.29 g at 20 weeks compared to the three local strains. The average body weights for the crossbred, Normal-feathered × Anak Titan at day-old and week 20 were 36.39 and 1,577.63 g, respectively. This was followed by Anak Titan × Naked neck with 33.32 g at day-old and 1,514.14 g at week 20. Sex had significant effect (P<0.05) at weeks 16 and 20 with the males having higher mean values than their female counterparts. This study revealed that crosses involving Anak Titan sire × Naked neck dam had highest growth performance, and there was no strain differences among the growth performance of purebred Nigerian local chickens.

“…All the body conformation traits at 6th week onwards demonstrated significant higher estimates for males than females (Table 1) in accordance to the earlier report (Das et al, 2014b;El-Safty, 2012). The present estimates of shank and keel lengths and breast angle were comparable to the earlier reports in RIR-White strain (Das et al, 2014b), Libyan native chicken (El-Safty, 2012), Ardennaise chicken (Lariviere et al, 2009), Kadaknath and Aseel (Chatterjee et al, 2007) and Giriraja and WLH chickens (Adebambo et al, 2006). The attributed difference was due to the different strain, line or breed studied different management and rearing system.…”

“…Literature regarding this sire-effect could not be made available. Significant sex-differentiation in this context was previously reported in RIR-White strain (Das et al, 2014b), native Libyan chicken (El-Safty, 2012), Ardennaise chicken (Lariviere et al, 2009) and Giriraja, Indian WLH and Nigerian improved indigenous chicken genotypes (F 1 , F 2 and B-α chickens) (Adebambo et al, 2006). Das et al (2014b) also obtained varied estimates of feed consumption along with body weight gain and or FCR in different feeding groups in RIR-white strain.…”

This investigation aimed to evaluate genetics of body conformation and feed efficiency characteristics in a selected line of Rhode Island Red chicken taking 100 numbers of single hatched out pedigreed chicks at Central Avian Research Institute (India). Data was analyzed by least squares analysis of variance. Least squares means of body weight, shank length, keel length, breast angle, body Weight Gain (WG), Feed Consumption (FC) and Feed Conversion Ratio (FCR) were estimated at various weeks of age. Sires of the chicks significantly (p<0.05) influenced the estimates of all the traits throughout the ages with a few exceptions. Chicks' sex also affected (p<0.05) the estimates of all the traits excepting 4th week body conformation traits, FC at 6th week onwards and 6th week FCR only. Male birds demonstrated better estimates than females throughout the ages. The FC and 16th week FCR also varied (p<0.05) among different feeding groups. All the traits excluding FC were heritable at variable magnitude. The estimates of genetic and phenotypic correlations coefficients were positive in trends with high magnitude among the intra-week body conformation traits and least to high magnitude among various feed efficiency traits. Only WG and FCR were invariably negatively correlated with a range of low to high genetic correlation coefficients. These research-outcomes may serve as base information to the breeders and academicians.

“…The presence of interaction between genotypes and seasons resulted to a reversal of the order of ranking between BN and IB genotypes, between late dry and early dry seasons respectively in cock body weight. This result negated the preliminary analyses of Adebambo et al (2006) in which they reported that the effect of interaction of breed with season was not significant in the same environment. The present study could have been found significant because we have used a 10-year data for the study.…”

Genotype sensitivity as a change in the relative performance of a genotype in the presence of two or more environments could be an important factor in the breeding of exotic birds in the tropics. Farm records covering 10 years (1999-2008) were employed to study the effect of seasons on genotype sensitivity and their usability for selection in the breeding of exotic Parent stock chickens of Bovan and ISA origins in SouthWest Nigeria. Cock weight, hen weight, Hen-day production, egg weight, fertility of eggs set, hatchability of eggs set and pullet day-old chicks hatched were examined. Sensitivity analysis was conducted using the regression procedures of Microsoft Excel, 2007. Results revealed a lack of significant difference between genotypes in sensitivity indices within seasons, in body weight, HDP and egg weight. Due to Interaction between genotypes and seasons, the genotype sensitivity values demonstrated lack of definite pattern with the output levels of FES and HES between genotypes. Genotype sensitivity in the presence of genotypeseason interaction, could be reliable for making choices between chicken genotypes in the humid tropics, especially in early dry season.
