Evaluación del comportamiento productivo y reproductivo en vacas con la utilización de tres niveles de carbo - amino - fosfo - quelatos

Abstract

In Yalancay farm located in Sibambe parish belonging to the canton Alausí, Chimborazo province, the effect of using three different levels of carbo-amino-phospho-chelates was evaluated (150, 175 y 200g), in feeding Holstein dairy cows in the first stage of lactation, which were compared with a control treatment, being distributed under a completely randomized design during 126 days of research. At the end of the experiment, the increased production of milk/day and total in cows supplemented with 175g carbo-amino-phospho-chelates as well as the best physical-chemical results of the milk were determined, presenting higher fat and protein content. Likewise by supplementing with 175g of mineral chelate, there have a significant reduction in days open, time of zeal and services per conception, and increased profitability for milk production, and indicator of benefit/cost $1,11. So we recommend using 175g/day CAQF as in the present investigation the best productive and reproductive outcomes were determined later to transfer the results to the level of small, medium and large producers, the use salts organic and supplementary alternative to improve the productive and reproductive performance. Besides as further research in deferent animal species using carbo-animo-phospho-chelates as a natural supplement of mineral salts in order to obtain information to assess reproductive yields especially in different livestock species is recommended.
