Broilers selected for higher growth rate eat more and generate more heat per unit of time; hence, they may become more sensitive to high AT. 6 Genetic group N %Incidence Genefrequency Carriersinthe population Normal 1594 78.44 Frizzled 223 10.97 F=0.06 F=0.94 11.64% Nakedneck 175 8.61 Na=0.05 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. This research investigated the effect of biochemical polymorphisms on performance traits in Nigerian indigenous chicken genotypes. These results are published and available to the farmers who want to keep certain types of chickens. Flock size is small, typically less than 100, and the family flock consists of birds of both sexes and different ages making management a demanding task. Adaptation of Nigerian indigenous chickens (NIC), FUNAAB‐α (F‐α) and Transylvanian naked neck chickens (TNN) raised during hot‐dry season under humid tropical environment was compared during a 4‐week period. Body weight at 4 and 7 wk, weight gain (WG) from 4 to 7 wk, breast meat yield, and feather weight were recorded.

Birds kept in deep litter system had higher least squares means values than ones in cage system of management. A formal survey, usintg a structured questionnaire integrated with Participatory Rural Appraisal techniques relevant to rural chicken production system, was applied. Polydactyl birds were significantly (P<0.05) superior in body girth and shank length compared with ptylopod and normal birds. The study covered three districts (Bijapur, Belagaum and Dharawad).The parameters included feather morphology, feather distribution, plumage colour, primary plumage pattern, secondary plumage pattern, skin colour, shank colour, ear lobe colour, comb type and colour and eye colour as per NBAGR proforma. Average household size was 7. Birds of each stock, genotype, and sex were reared under constant standard AT (24 C) or high AT (32 C). Currently, steps are being taken to protect against extinction of all that remains. Bohani Mtileni, Kennedy Dzama, Khathutshelo Nephawe, Clint Rhode, Estimates of effective population size and inbreeding in South African indigenous chicken populations: implications for the conservation of unique genetic resources, Tropical Animal Health and Production, 10.1007/s11250-016-1030-9, 48, 5, (943-950), (2016). 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. Data generated from the carcass parameters were subjected to least squares means using SAS 9.2 version 2008. There were significant (p<0.05) differences among body weights of the studied chicken strains with Noiler strain observed to have the highest body weight range of 2242.71-2389.00g. Introduction Indigenous chickens play important roles in the supply of animal protein and income to the rural populace [1]. High ambient temperatures (AT) decrease the growth of broilers because of difficulty in dissipating heat through the feather coverage. Mean chick weight increased by more than eleven times within the first eight weeks of life. The occurrence of feather pecking and cannibalism in LAB make this particular Labresse cross questionable for meat-type poultry production. In Africa, village poultry contributes over 70% of … The present work suggest that the potential of thermoregulatory Naked-neck and frizzle genes to improve body weight and body size may not be realized in Nigerian local chickens because of their small body size which confers them with a general adaptation. The spontaneous LL-like tumor incidence jumped from 14% by AF227 alone to 42-43% by AF227 in combination with SB-1 in the RFS chickens under controlled conditions. These chickens are also referred to as rural, village, backyard, scavenging, traditional or family chickens, and have various names in local languages. Nigerian indigenous cocks and hens exhibited lower BRE than others, except F‐α cock. The frequencies of the dominant genes carriers were between 0.02 and 0.03. In addition, the Agricultural Research Council in South Africa has established a programme to protect four local chicken breeds. chicken owners showed great interest to boost up indigenous chicken production and productivity. 0.0 0.2 0.4 0.6 0.8 1.0 Chicken chicken 2468 12 16 20 24 32 2 chicken 4 chicken 8 chicken 16 chicken Chicken Chicken chicken chicken, chicken chicken (chicken chicken) INDIGENOUS CHICKEN FLOCKS OF NASARAWA STATE, NORTH CENTRAL NIGERIA: THEIR CHARACTERISTICS, HUSBANDRY AND PRODUCTIVITY . The study was conducted to assess the preliminary evaluation of productive potentials of Nigerian indigenous chicken breeds versus Rhode Island Red chicken reared Southern Guinea Savanna environment of Nigeria. The chicks used in this study were hatched from a foundation stock of 90 chickens comprising 25 hens and 5 cocks for each of the three genotypes. This tool box will continue to improve as new methods and more rapid and less expensive methodologies are developed. Conclusively, daily monthly household income increased from N 475 ($ 2.2) to N 750 ($ 3.5) while egg and meat consumption increased by 200% and 100%, respectively. The effects of the Na allele were similar to or greater than those of the F allele. The study included two parts I. 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. Testing of disease resistance potential can be direct by infecting the host with the virulent pathogen (Okoye and Aba-Adulugba 1998, Mdegela et al., 2002) directly or by comingling, and response of the host towards the pathogen is evaluated. This study also generated the first piece of genomic evidence that suggests host transcriptomic variation may play an important role in modulating the LL-like lymphoma formation. 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. There were positive significant correlations between WIN and WAT in the three genotypes. Three diluents prepared using standard procedures were tested as extenders. Heart rate (HR), respiratory rate (RR), rectal temperature (RT) and skin temperature on comb (COM), wattle (WAT), breast (BRE) and under wings (WIN) were monitored between 13.00 and 14.00h twice a week for four weeks. 20 (2006) / Articles Genetic variation in growth performance of Giriraja, Indian white leghorn and improved indigenous chicken genotypes in South West Nigeria The body weight gain was highest in T 2 dietary group (P<0.01) which was statistically similar with T 1 group. (Oct., 1974), pp. Semen collection, evaluation and extension using the three diluents were carried out by standard methods. This experiment was conducted to determine the effect of sex, Polydactylism and rearing system on carcass parameters of Fulani-ecotype chickens. Fulani, FUNAAB Alpha and Shika-Brown had higher survivabilities (p FUNAAB Alpha/Noiler > Kuroiler > Fulani. Body weight in HE, MCX and RCX were on the average lowly to moderately heritable. In NIC, COM had positive correlation with WAT (r = .532) and WIN (r = .696). 102 birds were moved to outdoor houses with free access to an outdoor area. The results showed that those protein levels, except for ovotransferrin, in the least productive group significantly differed from the other three groups (p<0.05). 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). 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). Standard characterization and evaluation of particular populations of domestic animals may be carried out by using INTRODUCTION . In the other hand, many researchers have evaluated normal haematological parameters of industrial and … Thus, the present review provides genetic and performance information on INN chickens which may be useful for further improvement of tropical breeds. Although they are associated with poor productivity in terms of the number of eggs laid, most consumers prefer their flavoursome meat. Gene frequencies and influence of four major genes on body weight and body size parameters were studied in populations of adult local chickens in Nigeria. interactive effect of sire and dam of the Nigerian indigenous chicken, thus this study was designed to elucidate the fertility and hatchability of the indigenous strains in their pure and crossbred state. Nigerian local chickens (Ige et al., 2013) while homozygouse HBAA was reported for Muscovy ducks (Oguntunji and Ayorinde, 2015) and three varieties of Nigerian indigenous chicken … Survey study and II. nigerian indigenous chicken pdf: The project topic home for MBA, MSC, BSC, PGD, PHD final year student: Browse and read free research project topics and materials. Thirty chickens (15 males and 15 females) were randomly selected at 16 weeks old for carcass evaluation from population of the intensively (deep litter and cage system of management) kept Fulani eco-type chicken and were used for determining carcass characteristics such as Live weight, dressed weight, eviscerated weight, breast weight, Proventriculus weight, gizzard weight, liver weight, lung weight, spleen weight, bile weight, pancreas weight, heart weight, wing weight, shank weight, drumstick weight, thigh weight, head weight, neck weight, back weight. The objectives were to assess the flock characeristics, production and productivity of local birds and related constraints of village chicken production in studied regions. I. The results showed that levels of vitellogenin were positively correlated with total egg number at 24 and at 35 weeks old (p<0.01). Chicks weights were monitored weekly. The indigenous chickens represent valuable resources for livestock development especially in the rural poor's, this is because of their extensive genetic diversity which allows for rearing of poultry under varied environmental conditions. Eight healthy multiparous non gravid West African Dwarf (WAD) ewes and two sexually matured rams intensively managed on grass, fed concentrate and water (ad libitum) were used in this study. 15 for Nigerian indigenous chicken population, 1 for Giriraja and 1 for Anak titan from 23 polymorphic sites. The use of outdoor areas by two broiler strains, known to have different growth rates and with access to either moderate (M) or low (L) energy feeds, was examined to assess the consequences for production, meat quality, health and welfare. 1988;41(4):365-6.
