Evaluación del uso del flushing en la alimentación de cuyas primerizas y multíparas y su efecto en el tamaño de la camada al nacimiento

Abstract

In Tungurahua province, Patate Canton, Tontapi Parish, the effect of flushing in the feeding of gilt and multiparous female guinea pigs and its effect on brood size at birth was evaluated; 40 female guinea pigs were used, from which, 20 females of 4 months and 20 of a year were distributed under a completely at random with 10 repetitions, the TEU, was a female pig. The results were shown in the mutiparous guinea pig females with 959,30g postpartum weight and final weight of 971,65g; the birth weight was 136,20g; brood weight with 317,25g and at weaning weight 239,15g with a fertility percentage of 100%. With the use of flushing, females achieved a postpartum weight of 915,60g: final weight of 954,95g, brood size at brith of 2,65; birth weight 140,02g, brood weight 355,70g; brood size weight at weaning 2,55; weaning weight size 237,22g and brood weight at weaning 589,95g. The greater profitability in gestation-lactation stage was achieved with the inclusion of flushing on feeding pregnant female guinea pigs, being the benefits/cost of about $ 1,31 USD, representing a yield of 31%; by increasing economic yields on the exploitation of guinea pigs, therefore it is recommended to use flushing in their diet because it improves reproductive parameters during gestation-lactation stage supplying it 15 days before the breeding season, and 15 days after it, assuring this way, the embryo nesting
