Utilización de la Harina de Leucaena leucocephala (LEUCAENA) para la alimentación de cuyes en etapa de gestación y lactancia

Abstract

ABSTRACT1440 In the Academic Unit of Small Species of the Animal Sciences Faculty of the ESPOCH was used different levels of leucaena flour (10, 20 and 30 %), it compared to a control treatment was assessed; it was worked with 10 mothers whose was improved with an average of 1,09 kg; distributed under a completely randomized experimental desing with 10 repetitions per treatment; experimental results were subjected to analysis of variance and mean separation was performed by Tukey's test, determining that using the leucaena flour during the stages of gestation and lactation did not affect reproductive behavior of whose mothers. Nevertheless, with level 20 % higher birth weights and final weight post with 1,35 kg and 1,30 kg respectively was obtained. As for the young the best value litter size at birth was achieved with level 0 % to 3,50 offspring/ litter, while 20 % level with the best value pup weight at birth was obtained with 0,20 kg; in variables litter weight at birth, litter size and weaning litter weight at weaning, no significant differences were established. When performing economic analysis it determined that 30 % level using the most benefit/cost ratio reached 1,34; which means that for every dollar invested is recovered $0,34. Therefore the use of leucaena flour is recommended up to 30 %.
