Productive and reproductive parameters in four breeds of dual-purpose chickens (gallus gallus domesticus)

Abstract

This study was carried out to evaluate how four breeds of chickens (Rodhe Island Red, Orpignton, Plymouth Barrada and New Hampshire Red) respond to productive and reproductive parameters in the environmental conditions of the Experimental Field of the University of Oriente. Regarding methodological aspects, an experimental study was carried out with a randomized design, with four treatments (four breeds of dual-purpose chickens) and four repetitions. To find significant differences in the results of the treatments, the Analysis of Variance was applied ( ANVA) using the Excel 2013 program, in addition, to know the positions of the means when there were significant differences, the Tukey test was applied with a significance value at 5%. The results indicated which breeds reached a good weight that was around 2.24 to 2.51 kg, with no significant differences between the four breeds of chickens, the number of eggs laid in a year was better in the Rodhe Island Red breed with 135/eggs/year, while Plymouth Rock Barrada obtained the lowest amount with 73.20/eggs/year, another aspect is the weight of the egg that ranged between 51.43 and 56.29 g, with significant differences; In terms of reproductive parameters, the best birth rate was for the Orpigton breed with 78% and Rodhe Island Red with 74%. The best economic profitability is the Rodhe Island Red breed with a Benefit/Cost ratio of $1.36. Finally, it can be said that Rodhe Island Red, Orpignton and New Hampshire Red were the ones that had the best performance in the productive and reproductive parameters.
