Colour Gene

Background: An adaptive meat and egg type indigenous chicken is crucial for countries those depends on rural poultry production for meeting the protein requirements of the peoples. Genetic characterizations of native chickens have been documented, however, no study has observed the plumage colouration and its potential role in production traits. Thus, the aim of the current study was to know the effect of PME17, plumage colour gene diversity on production performance of indigenous chicken varieties.Methods: The plumage colours, comb and body shape of chickens corresponds with the live weight and egg production (clutch size) and the egg characteristics were recorded. Gel electrophoresis and polymerase chain reactions (PCR) were performed from blood cell DNA following standard protocols. The PCR products were sequenced using Sanger sequencing and for molecular analysis MEGA6 software were used. Result: Highest live weight (1400±25.4 g) and egg production (15.3±0.9 /number /clutch) was obtained in spotted-single-round chicken than other varieties. Both external and internal egg characteristics differed between varieties and spotted- single-round variety found to be best than other varieties. The sequence of PMEL17 gene was 99% homology with the sequence of Gallus gallus and Gallus gallus domesticus. A mutation was observed at 91bp nucleotide in brownish and at 64bp positional nucleotide and in black-white chicken variety.

Abstract Genetic limitation is one of the major bottle necks for the development of the poultry production and the expansion of the commercial poultry production is limited by inadequate supply of high performing chicken breeds locally in Ethiopia. Research system is currently attempting to alleviate this problem by introducing improved poultry breeds that can adapt and perform in Ethiopia. This experiment was carried out to study the on station egg production performance of Lohman Brown, Novo Brown and Dominant Sussex breeds under the objective condition of Jimma. One hundred fifty of each of Dominant Sussex, Lohman Brown and Novo Brown breed of layers obtained from Debre Zeit Research Station was placed at Jucavm layer house on standard commercial layers’ ration in completely randomized design with three replicates. Finally, all the data collected on performance of the experimental breeds of chickens were subjected to statistical analysis. There was no significant difference (P<0.05) between the three breeds tested in age at the first egg, even if Lohman Brown tended to lay comparatively earlier (137 days). The hen day egg production rate and egg weight of Dominant Sussex was better than other two breeds. In summary, the results of this experiment indicated that the three breed of chicken have well performed (except the adaptive potential of Dominant Sussex chickens) under Jimma condition in most of the economically important production traits studied. However, comparative evaluation of the egg quality and reproductive performance of the three breeds seems to be the future direction of research under objective condition of Jimma.

Enzyme Supplementation

The present study was conducted to assess the effect of supplementation of Multi-enzymes with lysophospholipids on production performance of pure line White Leghorn layers. Body weights before and after the experiment did not differ significantly across the experimental diets. Irrespective of the dietary treatments, the birds gained 3.83 per cent of live weight relative to its initial body weight. Mean per cent Hen housed egg production was significantly (Pis less than 0.05) higher in diet supplemented with 0.10 MEC-L than other groups. Mean egg weight and average daily feed consumption during 25 to 35 weeks of age indicated no significant effect of enzyme supplementation. Average daily feed consumption per bird in control, 0.05 % and 0.1% multi-enzyme supplemented groups was 108.13, 105.66 and 107.67 g respectively and birds offered control diet recorded numerically more feed intake than enzyme supplemented groups. Comparatively low feed per egg was observed in 0.10 per cent group followed by 0.05 per cent group which offers economic benefits than control diets. However, the egg quality traits between different dietary enzyme supplementation groups showed no significant difference.

The new original egg laying lines T, P and N selected at the Institute of Agriculture - Stara Zagora were used. Hybrid ?? ? ??, ?? ? ?? crosses were obtained and used for paternal line. Thereafter, the following breeding schedule of paternal and maternal lines was applied: Group I - (?????)? ?N?; group ?? - (?????)? ?N?; group ??? - ???N?; and group ?V - ???N?. The production traits of original and hybrid birds were recorded: live weight at the age of 8 and 18 weeks, age of sexual maturity in days, 150 days egg production, average egg weight - at 2-week intervals until end of lay; livability, heterosis effect. The live weights of hybrids at 8 and 18 weeks of age were statistically significantly lower compared to original lines. The values of heterosis for this parameter were negative for all four hybrid combinations. The earliest beginning of egg lay occurred in (?????) ? ?N? (162.08 days of age) and ???N? (163.11 days of age). The relative (%) heterosis for age of sexual maturity of studied hybrid combinations had moderate to low negative values. Average egg weights of hybrids were higher and the values of heterosis - positive for all four groups varying from 0.97% to 1.63%. The average 150 days egg production was lower in purebred lines compared to hybrids. The highest average 150 days egg production was determined in ???N? hybrids - 142 eggs. The heterosis effect for egg production in hybrids was significant.

Mineral Sources

Poultry production, health and wellbeing are highly dependent upon formulation of balanced rations in terms of energy, protein, and micronutrients (vitamins and minerals). Among all, minerals are required in fewer quantities, but they are very important to maintain the productivity in poultry. Minerals present in the feeds are less bioavailable and additional supplementation is obligatory to meet the physiological demands of poultry. Conventionally, minerals are supplemented as inorganic salts, which are less absorbed and, thus, a major proportion is excreted to the surroundings creating environment issues. Nano-minerals and organic mineral chelates are other alternative to be used as livestock and poultry feed supplements. Though organic minerals are more bioavailable than inorganic salts, their high cost limits its use. In contrast, nano-minerals are relatively easy to synthesize at a lower cost. Nano-minerals are of the size from 1–100 nm and due to such small size, there is an enormous increase in surface area and thus their biological responses. The biological response studies have signified better retention of nano-minerals as compared to inorganic salts, and consequently leached less to the environment preventing possible pollution. Apart from these, nano-minerals have been shown to enhance growth, egg production and quality, immune-modulation and antioxidant status, and at the same time economize the production by reducing the supplemental dose of minerals and improving the feed conversion ratio. Some nano-minerals and other nanoparticles have strong antimicrobial effects, which have been shown to reduce pathogenic microorganisms in the gut. Nano-minerals seem to be less toxic than conventional mineral sources. Though less, few studies have indicated toxic effects of nano-mineral supplementation at higher dose of application, which should be validated by more programmed studies. Nanotechnology in poultry production system is still in its budding stage and more detailed studies are warranted to validate, establish and search for new effects of nano-minerals as they sometimes produce effects beyond expectation. This review highlights the biological responses of nanominerals on poultry production performance, quality of meat and eggs, tissue retention, immunity, antioxidant activity and antimicrobial actions compared with their conventional mineral sources.

Application of different medicinal mushrooms intended to enhance production performance and health status has created an importance demand in poultry production. One goal of using medicinal mushrooms is to get rid of antibiotics in poultry feed without affecting the optimum performance. Increasing concerns about this issue have led to more attention on antibiotic substitutes and a significant demand for them for organic egg production. Thus, supplementation with medicinal mushrooms is a new concept for research in layer production, however, there is still a great deal of confusion about inclusion levels and the mode of action of medicinal mushrooms on production performance and health status in laying hens. Taking this into account, this review outlines the experimental uses of medicinal fungi on the growth performance, laying performance, egg quality, and health status of layer birds based on previous findings to date. Finally, we highlight that supplementation with medicinal fungi can play a role on the immunity, health, and production performance in laying hens.

Application of natural herbs with a view to enhancing production performance and health status has created an important demand in poultry production. With the increasing concerns on this issue, greater attention paid to alternatives to antibiotics for organic meat and egg production has led to a great demand. This study was conducted with view to assessing the possible role of M. oleifera as a natural feed supplement in poultry ration. Various scientific findings and published research articles were considered concerning issues including the study background, objectives, major findings, and conclusions of the review. M oleifera is known as a miracle tree because of its wealthy resource of various nutrients with high biological values. M. oleifera has been used as a growth promoter, immune enhancer, antioxidant, and has a hypo-cholesterol effect on chickens. It has both nutritional and therapeutic values. However, there is still much confusion in past published articles involving the major roles of M. oleifera in production performance and health status of chickens. Taking this into account, the present study highlights an outline of the experimental uses of M. oleifera on growth performance, egg production performance, egg quality, and health status in broilers and laying hens justified with the past findings to the present. The knowledge gaps from the past studies are considered, and the feasibility of M. oleifera in poultry ration is suggested. The findings have motivated further study on M. oleifera to find out the most active ingredients and their optimal doses in both broiler and laying hen rations. Finally, the present study highlights that supplementation of M. oleifera may play a role in the immunity, sound health, and production performance in poultry.

The study was undertaken from May up to July 2020 in Guder town of Oromia regional state, Ethiopia. The aim of the study was to explore husbandry practices and egg production performance of indigenous chicken in the study area. A cross-sectional systematic random survey of 40 households was undertaken by using semi-structured and pre tested questionnaire. Information on management practices, production systems, egg production performances and constraints of indigenous chicken kept in Guder town was generated by semi-structured questionnaire. The primary data collected from house hold survey was processed and analyzed by using a statistical package for social science (SPSS) version 20.0 software. Descriptive statistics such as percentage, mean, ranking, standard deviation, and cross tabulation were used to analyze the data quantitatively. Data gathered through key informant interviews, focus group discussion and personal observation was analyzed qualitatively to strengthen data obtained from the household survey. Due to its small space and lower capital requirement sample household’s ranked chicken as the first important animals kept in the study area. The main purposes of keeping indigenous chicken in the study area were for home consumption followed by generation of income. The most important feed resources of indigenous chicken kept in the study area were feed obtained from scavenging, house hold wastes, the market left over, and industrial by products. Majority of the households accommodated their indigenous chicken in a separate house constructed for the confinement of the chicken. The higher mortality rate of indigenous chicken in the study area was caused by disease and predator. The most commonly happening and economically important disease in the study area was Newcastle. The commonly observed predators in the study area were cat and dog. Health and feed problems were the first and the second constraint of indigenous chicken production in the study area respectively. Therefore area based development involvement could help to increase the productivity of indigenous chicken and thereby improve the income of small holders.

In this study, the effects of light stimulation at normal (NLS: 154 days) and early (ELS: 140 days) age on some physiological and reproductive traits in dam and sire broiler pure-lines were carried out during the laying period. The study was conducted with A1, A2, A3, A4 dam lines and B1, B2 sire lines up to 43 weeks of age, whose breeding studies were carried out in Eskişehir Geçit Kuşağı Agricultural Research Institute. Live weight and feed consumption were determined during the growing period. In the laying period, in addition to these, the first laying age, 50% yield age, egg yield, hatching egg yield and egg weight were determined. The data obtained were evaluated according to light stimulation age and pure-lines by two factor analysis of variance. NLS and ELS treatments did not significantly affect the body weights of the pure-lines at 20, 24 and 43 weeks of age. However, differences were found significant in terms of body weight at 20, 24 and 43 weeks of age in pure-lines. Lines reached the first laying age at 172 days in NLS, and at 165 days of age in ELS. The 50% yield age was realized at 184 d and 176 d of age in parallel with the first laying age. The effects of light stimulation age on egg yield and hatching egg yield were found significant. In NLS treatment all pure-lines, 5 more eggs were produced in egg yield and hatching egg yield. However, differences in egg yield and weight in pure-lines were found significant. The study results showed that the egg production can be increased by first light stimulation at the 20 weeks of age, provided that at least 2 kg live weight is achieved in broiler pure-lines.

Gain Loss

The relative economic weight (REW) of a trait is the additional gain/loss from a unit change in the trait relative to other traits in an individual. They are used to calculate aggregate economic values for purposes of genetic improvement in animals. The present study was designed to evaluate the bio-economic variables of growth and 16 weeks egg production parameters: egg number (EN16) egg weight (EWT16) body weight at first egg (BWTFE), body weight at 16 week of lay (BWTE16), cost of feed, and revenue from eggs and chicken carcass, 16 feed conversion ratio (FCR ), and body weight gain (BWG16) in the Nigerian indigenous chicken, and to determine the economic weights (EW) and REW of EN16, EWT16 and BWTE16 for G0, G1, and G2 generations. A total of 250 pullets (20 week old, point of lay) from a population of heavy body weight local chickens were used for the study. The birds were housed individually in cages, fed optimally on layers mash (G and G : 100g/bird/day; G : 0 1 2 125g/bird/day) and given water ad libitum. Data included EN , EWT , BWTE , BWTFE, 16 16 16 and prices of feed, eggs and spent hens, FCR , and BWG . Data on EN , EWT , BWTE , 16 16 16 16 16 and BWTFE were compared across generations using ANOVAand with other variables were used to generate the EW of the traits. The EW were then standardized relative to that of BWTE . Results showed that EW and REW of EN , EWT , and BWTE were 7.47 and 3.15, 16 16 16 16 13.67 and 5.77 and -2.37 and -1.00, respectively in G ; 13.07 and 3.82, 23.69 and 6.93, and - 0 3.42 and -1.00, respectively in G ; 16.80 and 2.89, 30.75 and 5.28 and -5.82 and -1.00, 1 respectively in G generation. Thus EN and EWT enhanced while BWTE depressed the 2 16 16 16 worth of the hen as a layer. EWT was more important than EN and both were more 16 16 important than BWTE economically. Therefore, EWT and EN are the major bio-economic 16 variables of the local hen as an egg chicken.

This study focused on investigating the reproductive performance of Nigerian indigenous chickens and their crosses with Marshall. The genotypes were normal-feathered (Nn), frizzle-feathered (Ff) and naked neck (Na) chickens, while the crossbreds with Marshall (M) breed were MNn, MFf and MNa respectively (Marshall being the sire while the indigenous are dams). Data were taken on; weekly egg production, weight at first egg and age at first egg. Genotype significantly (P<0.05) influenced egg production traits. Egg weight ranged from 23.71±1.06g to 26.13±0.94g for indigenous purebreds and 39.75±0.75g to 48.06±0.57g for crossbreds. Age at first egg were 165.63±0.61 days (Nn), 170.60±0.75 days (Na) and 173.57±0.52 days (Ff), 188.71±1.67 days (MNn), 187.50±3.16 days (MNa) and 185.25±5.44 days (MFf). Also, genotype significantly (P<0.05) influenced egg quality traits. Heritability for first egg production traits were 0.37 (Nm), 0.16 (Na) and 0.66 (Fz) while heritability estimates for egg quality trait (haugh unit) were 0.14, 0.07 and 0.08 for Nm, Na and Fz birds, respectively The crossbreds performed better than the indigenous purebreds in egg production traits. The Nigerian indigenous chicken can therefore be improved upon for better egg production traits using the Marshall breed.
