Evaluación de los Diferentes Niveles de Diatomea en la Fase de Crecimiento - Engorde de Cavia Porcellus (Cuyes)

2019 
In the province of Morona Santiago, Canton Sucua, the breeding of guinea pigs is done empirically with low yields. Therefore, three levels of diatoms were evaluated to control the treatment of growing weight and parasitic load (1.5, 3.0 and 4.5%) (additional T0) in 48 guinea pigs of the improved Peruvian line of 15 days of age and an average weight of 375.96 g. These were distributed under a Completely Random Design (CRD), which consists of a frequency of 6, and an experimental unit size of 2 guinea pigs per frequency. The data were applied to the analysis of variance, separation of meanings according to Tukey (0.05 and 0.01) and regression and correlation analysis. In relation to the results, the treatment T2 (3% of diatoms) reached a final weight of 964.50 g and an increase in the weight gain of 624.08 g. Also, the most efficient feed conversion is 6.66, while the lowest total food product with the T1 (1.5%) is 4113.05 g MS. It was determined that with the T3 treatment (4.5%), the parasitic load of 56.86% that was at the beginning of the experiment was reduced to 4.90% after 90 days. The highest profitability was the T2 treatment (3% diatom) with a benefit / cost of 1.19. This means that for every dollar invested, there is a yield of 0.19 dollars (USD). It was suggested then the growth stage should be applied i.e. 3% fattening of the diatoms in the diets for guinea pigs. This dose is the best when considering the productive and economic parameters. En la provincia de Morona Santiago, Canton Sucua, la crianza de conejillos de indias se realiza de forma empirica con bajos rendimientos. Por lo que se evaluaron tres niveles de diatomeas para controlar el tratamiento del peso en crecimiento y la carga parasitaria (1,5, 3,0 y 4,5%) (T0 adicional) en 48 cuyes de la linea peruana mejorada, de 15 dias de edad y un peso promedio de 375.96 g, que se distribuyeron bajo un Diseno Completamente Aleatorio (DCA), que consta de 6 repeticiones, y un tamano de unidad experimental de 2 cobayas por repeticion. Los datos se aplicaron al analisis de varianza, separacion de significados segun Tukey (0.05 y 0.01) y analisis de regresion y correlacion. En relacion a los resultados, el tratamiento T2 (3% de diatomeas) alcanzo un peso final de 964.50 g y un aumento en la ganancia de peso de 624.08 g; la conversion alimenticia mas eficiente de 6.66, el producto alimenticio total mas bajo con el T1 (1.5%) de 4113.05 g MS. Se determino que con el tratamiento T3 (4.5%), la carga parasitaria de 56.86% que estaba al comienzo del experimento se redujo a 4.90% despues de 90 dias. La rentabilidad mas alta fue el tratamiento T2 (3% diatomea) con un beneficio / costo de 1.19, lo que significa que por cada dolar invertido hay un rendimiento de 0.19 dolares (USD). Se sugiere entonces, aplicar en la etapa de crecimiento: engordar el 3% de las diatomeas en las dietas para conejillos de indias. Esta dosis resulta ser la mejor cuando se consideran los parametros productivos y economicos.
