Determinación de parámetros productivos en gallinas ponedoras de raza araucana en un sistema de semipastoreo

Abstract

The research was carried out at Hortensia Agro ecological Farm located in Pujilí County, Cotopaxi Province. Some productive parameters of Araucana type hens were determined under a semi shepherding system. To measure the productive parameters it was necessary to develop the analysis by using descriptive statistics emphasizing the central tendency measures (arithmetic mean) and the dispersion (standard deviation) in each one of the variables, the duration of the research was 90 days, in this way it was possible to establish important results which contribute the study of this type of hens. For the research it was necessary to use 250(20-week living) hens, this determined that each hen consumes about 0,081± 0,002 kilograms of food per day as well as the amount of grass 0,017 kilograms per day; egg laying 0,061 kilograms per day; weight gaining 1,514 ± 0,464 kilograms per hen; egg weight 0,009 kilograms per day and a food conversion of 2,64 with a standard deviation of 0,58; regarding to the bromatological analysis it was possible to determine that the eggs have a 61,83% of humidity, 38,17% dry matter, 7,10% protein and fiber not determined, 4,90% fat, 0,98% ashes and 99,02% organic matter; 0% of morbidity and the amount of money used to produce an egg is 8 cents per day. This is what makes this activity attractive since each egg can be sold from 20 to 30 cents in the market, in this way it is possible to obtain an excellent profitability using the materials of the area and putting aside the conventional growing and assuring the animal welfare and avoiding the bird confinement
