Análisis unifactorial de los efectos del despique en la producción de huevos de codorniz (Coturnix coturnix japónica) en la provincia de Tungurahua, cantón Ambato

Abstract

The research work was carried out in the Samanga sector in the Ambato canton, Tungurahua province in order to analyze the effects of trimming age, since at the farm level the producers seek better production and profitability with the innovation of new Such is the case of quail beak trimming, which is not widely practiced in this bird, carrying out an experimental study in which a completely randomized block experimental design was used using 40 birds per practice, which involved beak trimming in 21-day-old birds, being treatment T1, T2 after 28 days, T3 after 35 days and a control treatment with birds without after, with 4 repetitions that are evaluated for a period of two months. The results obtained were satisfactory for the T1 treatment, which in the different variables studied had good results by having the best production in the number of eggs, weight gain, feed conversion, lower mortality and at the behavioral level had the best behavior followed by the T2 treatment with with respect to treatments T3 and C, that in the latter a lower productive level was evidenced and higher mortality due to stress factors and aggression as a consequence of beak trimming, which increased mortality and therefore its profitability was lower, including waste due to food selection with 11.78% in terms of treatment T1 which was 17.02%. With a cost-benefit difference of the T1 treatment of 19 cents for every dollar invested with respect to the T3 treatment corresponding to the 35-day beak trimming because it was days prior to egg breaking, raising the birds to the cages, which increased the stress with consequence of a delayed weight gain suitable for egg laying
