Analysis of productivity and rearing technology of alternate progeny and adult chickens in Ross 308 and Cobb 500 lines combination

Name of the topic: Ross 308 combination of lines and Cobb 500 alternate progeny, and adult offspring rearing technology productivity analysis. Relevance of the topic: Chicken broiler production efficiency is closely related to the parent flock health, productivity, egg incubation and chick quality output. Health of broiler chickens and their immune system leads to the formation of optimal parent flock of birds holding, feeding, vaccination programs progeny. Therefore, the parent stock rearing is needed in order to achieve a good and cost efficient broiler production results. Target: To analyze the linear combination of Ross 308 and Cobb 500 replacement pullets and adult rearing techniques and factors affecting their productivity. The goals: to analyze factors influencing the mass development of replacement pullets, analyze and compare different combinations of lines, Ross 308 and Cobb 500 chicken production indicators, Make recommendations to improve the quality of hatching eggs. Results and recommendations: growing replacement pullets is important to ensure their optimal development and weight. Ross combination of lines 308 substitute chicken weight was from 16 to 125 g see comment on the recommended amount, while the combination of Cobb 500 lines from 27 to 207 g. Roosters' line weight combination ROSS 308 was higher from 11 to 410 g and 500 lines in combination with the Cobb from 51 to 376 g. Uneven light-controlled linear combination of the Cobb 500 replacement pullets reached through a combination of early sexual maturation. Linear Ross 308 chickens replacement mortality during the growing period is from 1 to 19 weeks were 3.33 per cent and linear combination of the Cobb 500 3.85 per cent. The analysis sheds in the production of replacement pullets climatic parameters revealed that the first days of cultivation the relative humidity was only 40 – 55 per cent, and the air speed of the last weeks of production was 0.52 to 0.68 m/s. hen hosting to see comment was 1m2 than 5.5 pc. Both lines of alternate combinations of chicken feed and water consumption and water ratio during the growing period did not meet the guidelines. The ratio of the individual replacement periods, growing replacement pullets was 1:2 – 3. Both lines of combinations of cocks and hens laying results over the entire weight of the period was slightly higher than the recommended dose. The analysis of adult chicken lines, the combination of the preservation of Ross 308 mortality was 6.3 per cent and a combination of lines, Cobb 500 14.3 per cent. This is higher than the recommended conservation of birds. The analysis of linear combinations of the two hens laying results, we found that Ross 308 hens laying results up to 47 weeks in line with the recommendations and the subsequent period was 0.9 -11.7 per cent lower. Basal Cobb 500 chickens laying results from 29 weeks of storage began to decline, and this difference was compared with recommendations from 1.6 to 22.2 per cent. The linear combination of chicken did not lay the maximum intensity. Egg weight of the combination of the two lines was slightly higher than the recommended weight. Broiler lines in combination with Ross 308 actual fertilization of eggs during laying results period was 1 – 18 per cent, and lines, the combination of Cobb 500 1 – 27 per cent, childhood, compared with recommendations. Qualitative analysis of egg incubation parameters such as shell weight, strength, protein height, yolk color intensity, the unit Hafo significant differences between the lines, the combination of Ross 308 and Cobb 500 was observed. The one-line combination of Ross 308 laying hens received 117, and a combination of lines, the Cobb 500 broiler day old 97 suitable for further cultivation. Meanwhile, the rearing guidance, this indicator should consist of 141 – 143 chickens. The analysis of linear combinations of the two alternate progeny production and adult productivity, found that the combination of Ross 308 lines of production and productivity rates were higher when compared with the linear combination of the Cobb 500 chickens productivity. In order to improve the replacement chicken rearing and parent flocks of hens laying results and hatching egg fertilization is recommended: Improve housing conditions for birds and chickens to achieve optimal development. To improve the microclimate of poultry houses to optimize water consumption, it is appropriate programs to reach feed and water consumption ratio of 1:2, follow the recommended duration and intensity of the light of recommendations to achieve optimum sexual maturation in chickens, hens placement density should not exceed 3.5 to 5.5 1 m2, the air velocity should not exceed 0.3 to 0.5 m/s and relative humidity on the first week of production of at least 60 – 70%. Increasing substitution of adult progeny of hens and cocks preservation, it is constantly updated to wild birds and pest control programs, constantly improving the health of birds and habitat preparation programs, and tightening of sanitary - hygienic requirements. To ensure the recommended hen laying results, fertilization of eggs and chickens to improve yield is recommended. chickens to produce a single feed enriched, containing the following: crude protein – 14 per cent, fat - 3.6%, calcium - 1.2 per cent, Sodium - 0.11 per cent, P - 0.70 per cent, lysine - 0.75 per cent, of tryptophan - 0.16 per cent, threonine - 0.49 per cent, chlorine - 0.17 per cent, manganese - 0.20 per cent, cystine - 0.25 per cent, methionine - 0.35 per cent, methionine + cystine - 0.66 per cent, linolenic acid - 1.27 per cent, in addition to feeding cock to install a separate feeder. Improving the fertilization of eggs and chickens in their health diets enriched with appropriate prebiotic (oligosaccharides) – 2 – 4 kg / t of feed. We introduce a new vitamin premixture for the parent stock hens and cocks with: Vit. A – 15,000 IU, D3 – 5,000 IU E – 150 mg, K3 – 7 mg B1 – 3,5 mg B2 – 16 mg, B6 – 6 mg, Niacin – 60 mg Pantothenic Acid –25 mg Biotin – 0.4 mg Choline – 70 mg
