“…The FUNAAB-alpha chicken was developed to meet the long-standing desire of farmers to have a strain of chicken that is thermotolerant and can be bred in tropical regions ( Adebambo, 2015 ). FUNAAB-alpha chickens have gained widespread acceptance among breeder farmers, but with ongoing research in different areas of production and their adaptation to the tropical environment, most breeder farms raising FUNAAB-alpha chickens still operate on a small scale ( Wheto et al, 2017 ; Yakubu et al, 2020 ). A variety of factors influence the quality of day-old chickens and, as a result, broiler performance.…”

“…The recently registered FUNAAB alpha chickens are one of the locally generated breeds in Nigeria that were specifically bred for tropical environments ( Adebambo, 2015 ). There has been a growing interest in FUNAAB alpha chickens by farmers as a replacement for the broiler chickens that are bred for temperate regions owing to their better heat resistance ( Wheto et al, 2017 ; Bamidele et al, 2019 ; Yakubu et al, 2020 ). This is because resource-poor poultry producers in less developed nations, who cannot afford a controlled environmental system, engage in poultry production using open-sided housing systems.…”

This trial was designed to evaluate the influence of hatching egg storage length and broiler breeder hens’ age on posthatch growth performance and physiological responses of FUNAAB-α chickens. Five hundred fertile eggs from each of 60 and 32 weeks old FUNAAB-α breeder hens were collected and assigned to 5 storage durations (0, 3, 7, 11 and 15 days). The hatching eggs were incubated using the conventional protocol. Data were collected on the growth performance and physiological responses. A 2x5 factorial design was used for the experiment. The results revealed that there was a decline in the final body weight in chickens from eggs of 15 and 11 days storage compared to the chickens from 7, 3 and 0 egg storage days. Chickens of 32 weeks old breeder hens had higher (p<0.05) mean corpuscular volume, white blood cell, heterophil and pack cell volume values compared to 60 weeks old breeder hens. Hatchlings from 60 weeks old breeders had a higher liver percentage (3.0% YFBW) than those from 32 weeks old breeders (2.8% YFBW). It was concluded that an extended storage duration of 15 days adversely affected the carcass traits and growth performance of chickens from egg storage above seven days.

“…The IGF-2 gene contains three exons and two intron maps to chromosome 5 (Darling and Brickell, 1996;Yokomine et al, 2001). Various studies revealed associations between IGF-2 gene polymorphism and economic traits of pigs, cattle, buffalo and chicken (Li et al, 2004;Yan et al, 2015;Wheto et al, 2016).…”

This research was conducted to estimate heritability of body weight and growth rate indices and also to determine their association with insulin-like growth factor-2 genes (IGF-2) polymorphism in purebred Nigerian indigenous chickens and their crosses with Marshal chickens. A total of 300 progenies were generated from the mating of three genotypes of F5 generation of Nigerian indigenous chickens (Normal feather (N), Frizzle feather (F), Naked neck (NN)) and Marshal (M) chickens. Blood samples were collected at twenty weeks for DNA extraction and IGF-2 gene amplification. IGF-2 gene was digested by restriction enzyme (Pst1) and genotyped using restriction fragment length polymorphism method. Growth rate indices (absolute (AGR) and relative growth rates (RGR)) were estimated and associated with IGF-2 gene polymorphism. The results show that IGF-2 allelic variants had no effect on the body weight (BW), AGR and RGR while chicken’s genotype effect was significant (p<0.01) on BW and AGR. Two crossbred genotypes (NxM,1524.23±137.20 and 1894.92±122.81), (FxM, 1445.19±177.24 and 1840.88±177.86) had better performance for AGR and BW, respectively, compared to the purebred of Nigerian indigenous chickens. The heritability values ranged from low (.06±.021) to high (.77±.24).
