Comparación del sistema de pastoreo continuo con y sin suplementación en toretes de engorde en la provincia del Guayas.

Abstract

Ecuador is known for being an agricultural and livestock country, one of the sectors with the highest production is beef production, where good pasture management is sought, increasing the weight of the cattle and obtaining a higher feed conversion rate. The objective was to compare two continuous grazing systems with and without supplementation in Brahman crossbred bulls for fattening in the province of Guayas, with a Completely Randomized Design (CRD) with 9 experimental units (repetitions) and 18 bulls (paired according to their weight) in two groups and 11 experimental weeks (2 weeks of adaptation). For both treatments, 10 hours of grazing (Janeiro - Eriochloa polystachya) with supplementation (T1) and without supplementation (T2) were used. Data were analyzed with the InfoStat statistical package, using analysis of variance (ANOVA). The functional analysis used was Tukey's test at 5 %, with a statistical significance level of 0.05, and comparisons were made on the results of the treatments. The results show that T1 had a total weight gain of 35.95 kg while T2 only achieved a gain of 33.35 kg. The adoption of good pasture management will improve weight gain and financial stability of the farmers, thus contributing to the sustainable development of the animals.
