Efecto de la mezcla de harina de cáscara de arroz y alimento tradicional en crecimiento y engorde de cerdos pietrain-duroc.

Abstract

The husk of the rice grain is a by-product generated in the cereal milling process, which is discarded or incinerated, which affects the environment; However, it contains a high content of insoluble fiber, a substrate for microbial fermentation, which contributes to the formation of a healthy colonic environment, stimulates motility, prevents constipation and improves the quality of feces in pigs. The objective of the work was to determine the effect of traditional food (made from chicken entrails and rejected banana) mixed with different amounts of flour (10, 15 and 20%) made from rice husk by measuring biweekly of the growth and fattening of pigs of the Pietrain-Duroc breed on the Pelaez farm at the La Primavera site, Canton Machala, province of El Oro, for this, a completely randomized design was developed with four treatments including the control, with eight replicates, consisting of pigs weaned at 40 days. Biweekly measurements were made for 60 days of height, width, length and weight of animals. The data collected in the field were tabulated and processed with the use of statistical software and the parametric test of analysis of variance of an intergroup factor was applied to determine the presence or absence of significant statistical differences between the treatments under study. The use of 20% rice husk flour to replace traditional food made from chicken entrails and cooked banana rejection constitutes an effective alternative that makes it possible to increase production, as well as reduce expenses and costs in the process of raising pigs of the Pietrain-Duroc breed, which may be associated with an increase in microbiota generated by the high fiber content and better use of nutrients. The reuse of the waste generated in the rice mill greatly reduces the environmental impact caused by the incineration of the cereal husk.
