Levante de corderos pelibuey con tres raciones alimenticias: brachiaria arrecta, silo de zea maíz y una pre mezcla balanceada.

Abstract

The present investigation was carried out at the "GANADERIA LA SABANA y CIA"farm located in the Naranjal canton of the Guayas Province; The objective of the research is to determine the weight gain of weaned lambs from four months of age, by feeding three rations: Tanner Pasture, Corn Silo; and balanced premix, to indicate which ration reflects greater weight and fattening in sheep. The study adds an exhaustive and beneficial effort to producers and control and support institutions for good management, in addition to avoiding significant losses in the production process and unnecessary expenses. The investigation was carried out with a population of 30 Pelibuey lambs with an average age of 4 to 5 months, which were distributed in 3 treatments with 1 replicate for each treatment. Each experimental pen had 5 lambs, which represented an experimental unit. The methodological approach that contributed to meeting the objectives of the study is quantitative, it recognized in each selected experimental unit the dose of the food rations (brachiaria arrecta, zea corn silo and a balanced premix). Regarding the research design, it was experimental because the observation units were managed directly by the researcher. The data collection of the weights was carried out every 7 days, the control of the real food consumption was carried out daily. The main results revealed for the weight gain indicator that T3 reached the highest weight (22.7 ± 7.99 ᵇ) compared to the other treatments, thanks to the additional food supplements that this treatment had as; pasture, corn silo and a balanced premix lete.For the accumulated food consumption variable, T1 presented the lowest weight because its diet was only based on grass, which did not cover the nutritional requirements of the lambs. Finally, in the food conversion variable, T3 was the best since the food concentration received by the lambs was more complete. It was evidenced that the supply of multivitamin drugs, growth factors, stimulants of organic functions, food supplements and increased dry matter intake had a positive effect on the weight gain of the lambs. In the weight gain variable, it was obtained that T2 and T3 presented the greatest gain, however, T2 is recommended as it is more economically viable and presents statistically similar results to those of T3, which was the one that presented the best weight agency. It is concluded , that there were statistically significant differences in the three treatments, being T3 the one with the best weight gain, gaining 22.7 ± 7.99 Kg at week 10. Factors such as the adaptability of the diet and nutrient deficiency influenced the loss weight of the T1 lambs. The hypothesis that the consumption of different feed rations influence the weight gain of the lambs is accepted, being the T2 and T3 ration the ones that presented the best performance
