Abstract. The effects of hypoxia at increased altitude levels on the cardio-respiratory development of broiler embryos are distinct in comparison with those at sea level. The aim of the study was to investigate the effects of high incubation temperature (H) and oxygen supplementation (O) during hypoxic high altitude (HA) on developmental and physiological traits of embryos and hatching performance of embryonated hatching eggs in broilers at different embryonic stages. A total of 1280 eggs obtained from broiler breeders laid at sea level were used. Eggshell quality characteristics were measured for 20 eggs. The rest of the 1260 eggs were divided into seven incubation condition (IC) groups (180 eggs per group) including a control group at 37.8 ∘C and 21 % O2; O groups, with daily 1 h 23.5 % O2 supplementation at 37.8 ∘C as O0−11, O12−21, and O18−21; H groups at 38.5 ∘C high incubation temperature at 21 % O2 as H0−11, H12−21, and H18−21 from days 0 to 11, 12 to 21, and 18 to 21 of incubation, respectively. All groups were incubated in three different incubators at hypoxic HA. The effect of IC was determined on eggshell temperature, hatching performance, embryo development, right ventricular (RV) to total ventricular (TV) ratio, and blood parameters. The highest egg water loss and embryonic mortality and the lowest hatchability were in the H0−11 group, which depended on increased eggshell temperature during incubation. On day 18 of incubation, due to the decreased egg water loss in the O12−21 and O18−21 groups, there was an increase in hatchability in fertile eggs similar to the middle and late H groups. Towards the end of incubation, embryo/chick weights were not different and RV and TV weights increased in the treated groups, and the RV ∕ TV ratio changed between 15 and 26 %. At hatching, yolk sac weight increased in H0−11 and H12−21 groups. The O groups had the lowest serum tri-iodothyronine (T3) concentration as distinct from H groups. The serum thyroxine (T4) concentration increased in the treated groups, dependent on sex of the embryo. Blood hemoglobin concentration of O groups decreased relative to other groups. The hematocrit value was the lowest in the O12−21 and highest in the H12−21 groups. The H and O treatments during pre-hatch hypoxic HA condition can be positively evaluated on physiological traits of embryos after half of incubation depended on the timing of the IC exposure to the hatching eggs obtained from broiler breeders at sea level.

Process Method

This research aimed to compare two female broiler breeder ages during the incubation period regarding management using the Analytic Hierarchy Process method (AHP). This method is characterized by the possibility of analyzing a multicriteria problem and assists a decision making. This study was carried out on a commercial hatchery located in São Paulo, Brazil. Two ages of broiler breeder (42 and 56 weeks) were compared relative to production rate. Production index data were the same in both ages and were submitted to multicriteria decision analysis using the AHP method. The results indicate that broiler breeders of 42 weeks presented better performance than those of 56 week-old. The setter phase (incubation) is more critical than the hatcher. The AHP method was efficient for this analysis and can serve as a methodological basis for future studies to improve the hatchability of broilers eggs.

The impacts of egg weight (EW), egg shell temperature (EST), egg position in the incubator (EP) and incubator ventilation program (IVP) on embryonic mortality (EM) and hatchability of fertile eggs (HFE) of broiler breeders were investigated in this study. EW was determined total 1920 hatching eggs which were obtained from middle aged (31 weeks) Ross 308 broiler breeders. These eggs were classified according to weight as heavy (65.52±0.08g), medium (61.47±0.04g) and light (57.56±0.08g) then were randomly set in trolleys of four identical incubators sorted as near the heather side – door side, humidifier side – opposite side and top – middle – bottom. In two incubators 37.78°C (100.0°F) EST and 38.06°C (100.5°F) EST were provided in the other two. Similarly, two machines were operated on classic IVP system and the other two were operated on new IVP system organised specially for this project during first 10 days of incubation. At the end of the hatching period, data including EM and HFE data were examined in eggs with different EST, EW and EP. It was found that EW and EST were affected to EM and HFE. Lower last stage + pipped but unhatched embryo rates and accordingly higher HFE were determined in eggs with 37.78°C (100.0°F) EST and light. However, differences between IVP and EP data were not significant.

The present study was designed to investigate the impact of in-ovo injection of folic acid and glucose on hatching eggs from 55 weeks old broiler breeders. A total number of 900 hatching eggs were collected from Arbor Acres broiler breeders, then, eggs were divided into 6 groups including 1) Negative Control (non-injected, NC), 2) Dry Punch Control (pricked without injecting any solution, DPC), 3) Positive Control (eggs were injected with 0.5 mL normal saline, PC), 4) Folic Acid group (eggs were injected with 0.2 mg/ egg folic acid, FA), 5) Glucose group (eggs were injected with 125 mg/ egg glucose, Glu), and 6) Folic Acid with Glucose group (eggs were injected with 0.2 mg folic acid with 125 mg/ egg glucose, FA+Glu). Each treatment was divided into five replicates of 30 eggs each. Eggs were injected into the albumen under the air sac. After in-ovo injection, the eggs were stored for four days before hatching. After hatching, the chickens were reared in groups according to the treatments. All treatments were divided into 10 replications of 9 chickens in each. In-ovo injection with folic acid decreased the albumen pH significantly to 9.19 after 4 days of injection, while the negative control was 9.43. Hatching quality was severely affected by all in-ovo injection treatments, but no significant differences were found between the treatment groups concerning the hatchability of fertile eggs. Injection treatments had no significant effect on the growth rate or the production number in any of the weeks. Injection of folic acid and (FA+Glu) significantly increased chickens’ body weight at two and four weeks of age. Also, the dressing percentage when using folic acid and (FA+Glu) was significantly increased to 72.1% and 72.5%, respectively, compared to the positive control group (68.3%). In conclusion, our data suggested that in-ovo injection with a mixture of folic acid and glucose (0.2 mg folic acid+ 125 mg/ egg glucose) could be used to enhance carcass characteristics. Further studies should be conducted to find the effects of in-ovo injection folic acid and glucose on different incubation days and at different sites of injection.

Positive Effect

More and more probiotics are used in poultry feeding. Understanding that the inclusion of beneficial microorganisms in the diet contributes to the normalization of intestinal microflora serves to prevent metabolic disorders, improves the activity of the gastrointestinal tract, increases immunity and, as a result, has a positive effect not only on the health of the bird, but also on its productivity indicators. Therefore, the purpose of our study was to establish the effect of the probiotic Levusell SB Plus on the productive qualities of hens in broiler breeders. The experiment was carried out in the production conditions of Kamenskaya Poultry Farm LLC, Kamensky District, Altai Territory on hens of the parent stock of the Ross 308 cross. The use of the probiotic Levusell SB Plus at a dose of 1.0 kg/t as a part of the complete feed for laying hens of the parent stock at the age of 23 to 63 weeks led to an increase in poultry livability, an increase in the total egg production and the intensity of egg-laying capacity. The addition of a probiotic to the poultry ration contributed to the optimization of the egg weight, an increase in the yield of hatching eggs, an increase in the hatch of chickens and the yield of broilers per initial layer by 3.9%.
