Evaluación de respuestas productivas de ovinos mestizos sometidos a estrategias de alimentación mineral en la comunidad Las Cayanas.

Abstract

In the sheep farming area of Orellana province, animals that are destined for sale take longer than necessary to go to market due to a deficit in mineral feed; taking into account that the only source to cover these nutritional requirements are those offered by fodder. Therefore, the objective of the current research was to determine the live weight gain in backyard crossbred sheep supplemented with mineral salt in the community of “Las Cayanas". The methodology implemented had a quantitative and qualitative approach where 27 male and female of the Pelibuey and Black Belly breeds were selected, 9 animals were separated by treatment with an average weight of 25.84 kg for T0; 27.51 kg for T1 and 28.71 kg for T2, then mineral salt was added according to the treatment in amounts of 100g; 105g and 110g respectively. Through this methodology, significant results were obtained from the third week onwards, where T2 showed 12 percent more weight compared to T0, although similar to those obtained for T1 (35.57 vs. 33.82 plus minus 1.3kg) The body condition showed highly significant differences, where T1 and T2 with an average of 2.83 plus minus 10 were superior to T0 which showed a body condition of 2.55 plus minus 0.07, while the cost benefit of T2 showed higher profitability with gains of 0.29 and 0.60 cents for each dollar invested. Finally, it is concluded that the supplementation of minerals in the sheep diet provides positive results in terms of profitability and productivity; being a production alternative for small and medium producers.
