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.

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.

In poultry production, the intensive use of high-performing hybrid animals led to loss of genetic variability and a consequent lower response to climatic change and disease. Poultry biodiversity is seriously threatened, and its safeguard is a strong objective in developed countries. According to the FAO, which emphasized the importance of native breeds for its country of origin, the aim of this study was to present the first contribution on eggs quality for endangered the Siciliana chicken breed and deepen knowledge on the local Livorno breed. At 20 weeks of age, 108 laying hens (54 Siciliana breed and 54 Livorno breed) were divided into six homogeneous groups of 18 hens each and reared according to requirements imposed by the EC Regulation 889/08 for organic production. The production cycle was controlled over one year, and egg production was recorded daily by group. Eggs were collected, weighted, and measured. Physico-chemical parameter and fatty acids profile were analyzed and nutritional indexes calculated. The statistical model included the effects of breed (Siciliana, Livorno). Egg production was 190 egg/head for Siciliana and 180 for Livorno group. The results showed similar values for Siciliana and Livorno egg quality, highlighting several valuable quality traits from these breeds which might be taken into account for conservation programs.

The main objective of this research is to evaluate the inclusion of different natural pigment solutions in diets formulated with maize and sorghum solutions on the growth performance and egg quality of commercial laying hens created in hot climates. Throughout the conduction of this experiment, were used 252 laying hens of the Hisex Brow, in a completely randomized design, with six treatments, seven repetitions, and six birds per plot. The experimental diets were assigned with different energy sources and adding pigmentation solutions, diet 1 (corn), diet 2 (corn + annatto), diet 3 (corn + carrot), diet 4 (sorghum), diet 5 (sorghum + annatto), diet 6 (sorghum + Carrot).  Afterward, being evaluated the performance and quality of eggs. It was observed significant difference with reference t egg production, egg weight (g), gem weight (g), the weight of shell (g), albumin in weight (g), and gem coloration (tons) among the treatments. There was no difference in the parameters of performance and quality of eggs evaluated, only the variable yolk color had a significant effect between treatments. Replacing the energy source of the corn diet with sorghum in the diet of laying hens at peak production provides similar performance and egg quality, which can be a substitute for quality and efficiency. The use of annatto and carrots as a natural pigmentation promotes greater pigmentation of the egg yolks of laying Hisex Brown eggs and does not impair the performance of the birds.

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.

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.

Abstract In the era of increased antibiotic resistance and ever stricter control on antibiotic use, it is urgent to develop green, safe and non-residue alternatives to antibiotics applied to the poultry industry. To this end, we supplied the potential Lactobacillus Plantarum (L. Plantarum) fermented Astragalus in the diet of laying hens, with a final addition of 3‰. Its effects have been assessed on laying performance, egg quality, antioxidant and immunological status and intestinal microbiota, and are compared to the control group, to the Astragalus group containing 3‰ unfermented Astragalus, and to the L. Plantarum group containing 2% L. Plantarum (1 × 108 CFU/mL). During the second half of the experimental period (15 to 28 days), the egg production rate was significantly higher in the fermented Astragalus group than that in the other groups, with the fermented Astragalus group having the lowest feed conversion ratio. No significant difference (P > 0.05) was observed among treatments on egg quality. Fermented Astragalus-treated hens exhibited significantly increased catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in serum, and reduced malondialdehyde (MDA) in serum. Furthermore, fermented Astragalus supplementation resulted in a significant increase in ileal microbiota abundance relative to control. In conclusion, feeding laying hens with L. Plantarum fermented Astragalus has beneficial effects on production, antioxidant potential, immunity and ileal microbiota. L. Plantarum fermented Astragalus is expected to be a novel feed additive used in poultry production.

The aim of this study was to evaluate the performance and egg quality of laying hens given peat water (PW) and non-peat water (NPW). This study used 30 laying hens strain lohman brown aged 15 months with commercial ration feeding. The study consisted of two groups of chickens with 15 chickens each. The first group was given PW and the second group was given NPW. The variables observed were water consumption, feed consumption, egg production and mass, FCR, egg weight, albumin and yolk index, egg shell thickness and haugh unit value. Data obtained were analyzed using t-test to determine the differences between treatment groups. The results showed that water consumption, feed consumption and FCR were statistically difference. The daily water consumption in PW treatment (286.57 ml/bird/day) was higher than in NPW treatment (264.24 ml/bird/day), as was ration consumption (98.82 g/bird/day vs 90.10 g/ bird/day). While the ration conversion in PW treatment (2.71) was better than that of NPW treatment (3.18). In the egg quality variable, only egg weight showed a significant difference. Egg weight in PW treatment (55.85 g/egg) was higher than in NPW treatment (54.18 g/egg). The conclusion of this experiment was the given peat water to laying hens was able to improve the production performance, indicated by water consumption, feed consumption and FCR. Meanwhile, the quality of eggs can only be seen from the egg weight.
