In Nigeria, under on-farm conditions, Noiler (166.2) and Funnab alpha (117.6) were best performers with 269.3 and 161.3% productions above the indigenous chicken in similar conditions. Ukraine and Poland are also remarkable for the large poultry genetic resources numbering respectively 20 (eight of chickens, one of turkeys, four of ducks and seven of geese) and 18 (seven of chickens, two of Japanese quail and nine of geese) native breeds, varieties and strains. Several studies have been conducted on the nutritional requirements of local chickens, but the results were inconclusive and contradictory. Two reports in this issue of Science ([ Ando et al . These superiorities were however not statistically significant (P>0.05). The effects of the Na allele were similar to or greater than those of the F allele. No Abstract.Nigerian Journal of Genetics Vol. About 50% of the eggs produced are incubated in order to replace birds that die. They are the Fulani Ecotypes and Forest savannah (Yoruba) Ecotypes. The purpose of this review is to provide a detailed understanding of the description, uses and conservation methods of local chicken breeds of Africa. Baseline survey was conducted to provide a benchmark for both the on-farm test and post-on farm survey. Chicks weights were monitored weekly. The study investigated growth, laying performance and survivability of six improved dual-purpose breeds in five agroecologies of Nigeria represented by the following states: Kebbi (Sudan savanna/northern Guinea savanna); Kwara (northern Guinea savanna/southern Guinea savanna); Nasarawa (southern Guinea savanna/derived savanna); Imo (lowland rainforest/swamp); and Rivers (freshwater swamp/mangrove swamp). strains of chicken used were Nigerian indigenous chicken (NIC), ISA Brown (IB) and Nera Black strains (NB). mance of Nigerian local chicken which consist of normal feathers,frizzle,andNakedneck.Sola-OjoandAyorinde[ ] documented the Fulani ecotype of Nigeria. You can download the paper by clicking the button above. A total of 144 twelve weeks old pullets comprising 24 each of Normal feather (NF), Naked Neck (NN), Shika Brown (SB), Isa Brown (IB), Bovan Nera (BN) and Noiler (NO) chicken strains were used. There are basically three different breeds of bird for poultry business; Broilers, Cockerels, and Layers. 2 1.2 Problem statement. It is important to stem the negative selection against the dominant alleles through village level extension service. Egg number and egg weight of the improved breeds were also higher than the values of 30 and 35g reported for local chickens. effluents, animal welfare...In parallel, methods are improving thus allowing a better modelisation of traits and of genetic effects but also an integration of results of molecular information. This study investigated the relationship between serum protein levels and egg productivity in Taiwan red-feathered country chickens (TRFCC). There are a very few published papers on the molecular aspects of INN chickens, although this is essential to determine genetic distance or relationship within or between INN chicken and indigenous full-feathered (IFF) varieties (D. nana) for future breeding plans. All the forms of feed were of identical (pellet feed) as, 1. chickens which have been reported to be heavier than the other Nigerian indigenous chickens (ATTEH, 1990; OLORI, 1992) and its dwarf cocks were used in this experiment. improvement of the Nigerian indigenous chicken by crossing with an exotic egg type strain Isa Brown. Hen day egg production (HDEP) was higher in Shika-Brown (45.9 %), FUNAAB Alpha (45.8 %) and Kuroiler (45.7 %) compared with the other breeds. A total of 214 pedigree hatched day old chicks of HE, 190 day old chicks of MCX and 185 day old chicks of RCX from a total of 15 sires were used in the study. Management of birds in a controlled environment may help to further prove the superiority of polydactyl and ptylopod birds. This makes the reproduction for replacement as the main focuses of chicken keepers. The indigenous chicken breeds of Africa play a very vital role in the socio-economic life of their keepers, providing them with readily available meat, egg ( Kitalyi 1998; Zaman et al 2004) and manure. Semen collection, evaluation and extension using the three diluents were carried out by standard methods. Thus, this present review provides genetic and performance information on naked neck, frizzled and normal feathered chickens which may be useful for breed improvement and development for future generation. Indigenous chicken are the most abundant livestock in many rural and peri-urban households in Kenya. [2]: http://www.sciencemag.org/cgi/content/short/279/5359/2106 Haemoglobin genotypes in the Nigerian indigenous chicken 4 necked neck(52.63%) and the least value of genotype AA(6.67%) was equally recorded among the frizzled feathered chickens. For each of the surveys, structured questionnaires were developed, tested and administered using the Open Data Kit data collection tool pre-installed on Lenovo tablets (Model: Lenovo TAB 2 A7-30H). Heritability estimates of daily gain were generally low in HE and RCX with a range of h2 = 0.04 ± 0.13 to 0.12 ± 0.14. feed conversion ratio had moderate h2 estimate in all the genetic groups. In study three, sixty-eight day-old Fulani-ecotype chicks were evaluated for growth performance. The studies carried out so far suggest that in the countries of Eastern Europe there is awareness of the necessity to maintain for future generations established, native breeds of poultry not only as genetic resources indispensable for further breeding activities, but also as live evidence of the great achievements of many generations of past breeders. A total of 601 chicks was hatched from all possible mating sbetween the three genotypes. The objectives were to assess the flock characeristics, production and productivity of local birds and related constraints of village chicken production in studied regions. The African Chicken Genetic Gains (ACGG) project is a 15-million US Dollars 5-year research-for-development (R4D) partnership being implemented in Ethiopia, Nigeria and Tanzania by the Internationa. Academia.edu no longer supports Internet Explorer. During the on-farm study, supplementary feed and vaccination services were provided for the birds, while the households received trainings on poultry management practices. Molecular genetics is providing the tool box of the 21st century for the modern poultry breeding company. Most advanced in the programme of preservation of the native breeds of chickens, turkeys, ducks, geese and other domestic and game birds are: the Czech Republic, Hungary, Poland, Romania, Russia, Slovakia & Ukraine. MATERIALS AND METHODS The experiment was carried out at the Teaching and Research Farm, University of Port Harcourt, Port Harcourt (5.14’N and 6.44’E). Body size parameters measured were body length, body girth, wing length, keel length, shank length, shank diameter and toe length. In addition, the Agricultural Research Council in South Africa has established a programme to protect four local chicken breeds. In conclusion, a mixture of 10% pawpaw juice and 90%coconut milk-citrate was as effective as EYC and could be optimally used as an extender for ram semen stored at room temperature for up-to 6 hours, Chickens kept under free-range, backyard or semi-intensive systems in the developing countries have more diverse use and benefits to rural households. This review work aims at determining the potential usefulness of the Nigerian indigenous ecotype chickens and the effect of the major genes of frizzling and naked neck for poultry production in the tropical humid climate. An experiment was carried out to evaluate some reproductive and growth traits of Nigerian indigenous light ecotype and exotic chicken for possible egg and meat-type chicken development. Results showed that least square means of live weight, wing and shank length, body, thigh and toe length, beak length and breast breadth of the Fulani ecotype were generally higher (P<0.01) than those of the Yoruba ecotype. Body weight (BW), average daily weight gain (DG) and feed conversion ratio (FCR) were measured at 4-weekly intervals in all the genetic groups. The total egg numbers of TRFCC (n=157) were recorded from 25 to 48 weeks of age. Data generated from the carcass parameters were subjected to least squares means using SAS 9.2 version 2008. Except the body weight (P<0.01) no significant results were observed for sex(s) as well as interaction between treatment and sex effect for all other meat yield parameters. The authors are aware of the limited range of the presented material but a serious drawback has been the lack of information available from Albania, Bulgaria, Byelarus, Estonia, Latvia, Lithuania, Moldova and former Yugoslavia. The third diluent (Standard Egg-yolk citrate) served as a control. Nigerian indigenous cocks and hens exhibited lower BRE than others, except F‐α cock. Both polydactyl and ptylopod birds were superior to normal birds in all the measured traits, except for the shank length. Combining the two allles resulted in an additive effect, which was more pronounced in the high-GR stock. The Nigerian poultry industry is estimated at ₦80 billion ($600 million) and is comprised of approximately 165 million birds, which pro-duced 650,000 MT of eggs and 290,000 MT of poultry meat in 2013. Nigerian Indigenous Chicken: A Valuable Genetic Resource for Meat and Egg Production: F.O. Bangladesh Journal of Veterinary Medicine. Corpus ID: 6087611. October 2010; Asian Journal of Poultry Science 4(4):2010; DOI: … A. Ibrahim Abstract : The study was carried out to assess the fertility, early and late embryonic mortalities as well as hatchability by strain, season and hen’s weight in Nigerian indigenous chickens reared on deep litter. These chickens are known to be economically, socially, and culturally important to the people of Africa, especially those from marginalised communities. Two broiler stocks were studied; each was segregated for four genotypes with regard to the genes for naked neck (Na) and frizzled feathers (F): heterozygous naked neck (Na/na f/f), heterozygous frizzle (na/na F/f), double heterozygous (Na/na F/f), and normally feathered (na/na f/f). The aim of this study was to evaluate chickens from three different agro-ecological zones for their reproductive and growth performance. Genetic and Sex Differences in Carcass Traits of Nigerian Indigenous Chickens @article{Isidahomen2012GeneticAS, title={Genetic and Sex Differences in Carcass Traits of Nigerian Indigenous Chickens}, author={C. E. Isidahomen and B. M. Ilori and K. Akano}, journal={Journal of Animal Science Advances}, year={2012}, volume={2}, pages={637-648} } The major genes studied were Naked-neck (Na), frizzle (F), polydactyly (Po) and ptylopody (Fsh). 3. Heritability estimates of body weight of 0.43 and 0.30 for heavy ecotype chicken at 8 and 20 weeks, respectively is an indication that the heavy chicken ecotype may possess dual potential to be selected as meat type or egg-type bird because 8 weeks and 20 weeks of age are broiler and layer ages, respectively. This research investigated the effect of biochemical polymorphisms on performance traits in Nigerian indigenous chicken genotypes. Data from this study provided an additional piece of experimental evidence on the potency of nonpathogenic ALV-E, MDV-2, and ALV-E plus MDV-2 in boosting the incidence of LL-like lymphomas in susceptible chickens. Chicken Astroviruses in Nigerian Indigenous Chickens 1Oluwayelu D. O. and 2Todd D 1Department of Veterinary Microbiology and Parasitology, University of Ibadan, Ibadan, Nigeria 2Agri-Food and Biosciences Institute, Stormont, Belfast, United Kingdom ABSTRACT: Poultry have gradually assumed a very important role in the economy of many industrialized and developing countries. Purchase was the main source of stock for foundation while hatching and purchase were the main sources of replacement stocks. Average household size was 7. This tool box will continue to improve as new methods and more rapid and less expensive methodologies are developed. ALSO READ: The Nutritional Requirements of Chick, Pullet & Layer. The underlying mechanism may be complex, potentially involved with many chicken genes and pathways including signal transduction pathways and immune system processes, in addition to reported viral genes. These tools allow for rapid and accurate identification and selection at the gene level of those individuals with better performance traits. To prevent this, the Food and Agriculture Organization has launched an indigenous poultry conservation programme. These chickens are also referred to as rural, village, backyard, scavenging, traditional or family chickens, and have various names in local languages. The performance of the breeds was significantly (p. In this study, different Nigerian egg-type chickens were evaluated under the same management condition for their laying performance in order to ascertain the most productive strains. There were positive significant correlations between WIN and WAT in the three genotypes. (2010): Nigeria indigenous chicken: A valuable Genetic Resource for meat and egg production. African indigenous education was a lifelong process of learning where by a person progressed through predetermined stages of life of graduation from cradle to grave. 2Agri-Food & Biosciences Institute, Stoney Road, Stormont, Belfast BT4 3SD, United Kingdom. This together with the presence of pectoral myopathies make ROSS unsuitable for 12 week growth in free range production systems. Overall, the number of households consuming eggs increased by 50% (54%-84%) while there was a 60% (47.7%-76.5%) increase in the number of households eating chicken meat. Vaccination with serotype 2 MD viruses, SB-1, in addition to AF227 or AF229 inoculation, significantly enhanced the spontaneous LL-like tumor incidence in the RFS chickens. Ten eggs per strain were randomly selected for breakout at embryonic day (ED) 7, 11, 15, and 18 of incubation to collect data on albumen weight in order to determine the embryonic albu-men reduction rate during incubation and yolk weight to monitor its utilization. This study was conducted in five different agro-ecological regions in Ethiopia. Birds of each stock, genotype, and sex were reared under constant standard AT (24 C) or high AT (32 C). A total of sixty (60) 16 weeks old chickens were used comprising of twenty (20) chickens per variety.

Normal feathered birds were superior to Naked-neck and Frizzle birds in most of the metric traits. The Broilers grows very faster, the Cockerels grows slower before they are matured for marketing. This study was designed to test the impact of two new ALV-E isolates, recently derived from commercial broiler breeder flocks, in combination with the nonpathogenic SB-1 on LL-like lymphomas incidences in both an experimental egg layer line of chickens and a commercial broiler breeder line of chickens under a controlled condition. Mean clutch number was 2.6±0.06 per year.
