Elaboración de bloques nutricionales mediante el uso de diferentes niveles de Baccharis latifolia (Chilca) en la alimentación de cuyes en la etapa de crecimiento-engorde

Abstract

They were made nutritional blocks through the use of different levels of chilca (baccharis latifolia) in the feeding of guinea pigs in the growth-fattening stage, in the Parish of Augusto N. Martinez, Ambato canton, Tungurahua province, using 80 male guinea pigs of the improved 15-day line; with an average heavy of 379 grams, with four treatments (5, 10, 15 and 20%) based on chilca (baccharis latifolia) comparing them with a witness treatment, it was applied a Design Completely at Random (DCA) with 8 repetitions and the Size of the Experimental Unit (SEU) was of 2 animals. The data were collected daily in the case of food weighing, waste, and also of initial and final weigh; we estimate the weight gain, weight conversion, weigh and production to the canal. The experimental results were subjected to an analysis of variance (AOVA) and a separation of media according to Tukey with level of significance of (P>0.05), reporting that the final weight, weight gain, food consumption, food conversion, during the growth and fattening stage of guinea pigs, fed with nutritional blocks (adding different levels of flour of chilca (baccharis latifolia)), they didn´t report specific differences among the studied treatments (P>0,05), while the parameters, weight to the canal and production to the canal did show significant differences (P<0,05); demonstrating that the use of chilca flour doesn´t alter the growth and development of the guinea pigs. Bromatologically, the results obtained of the nutritional block using the 20% of chilca flour get the following results: humidity 16,53%, proteins 15,38%, ethereal extract 4,22%, ashes 9.90%, fiber 8,43%, and nitrogen free extract 45,53%; these numbers cover the nutritional requirements for the normal development of the guinea pigs in the growth-fattening stage, without altering their normal growth. It is concluded that it is possible to include in the feeding of guinea pigs, during the stage of growth-fattening, until the 20% of chilca flour, in the elaboration of nutritional blocks by observing that the biological behavior don´t be affected, we recommend to use the nutritional blocks based on chilca and other species of zootechnical interest (guinea pigs, pigs), due to the nutritional contribution presented by this food.
