Estudio de Diferentes Niveles de Lasolacid en la Alimentación de Vacas Holtein Mestiza en la Hacienda Pucate, Barrio Julquis, Cantón Chambo, Provincia de Chimborazo

Abstract

In the hacienda Pucate of the Julquis neighborhood, Chambo canton, Chimborazo, province, the study of different lasolacid levels in crossbred Holstein cows feeding was carried out using 12 experimental units studied unde a completely random block design, with 4 treatments (200, 300 and 400 mg lasolacid), including the control and 3 replications per treatment. The results show a higher production of milk / cow / day in the morning (8.05 I / v / d) in treatment T3 (400 mg), as well as a higher weight at 45, 60, 75, 90,105 and 120 days, with 539.33, 547.00, 553.67, reporting statistical 563.00, 568.33 and 573.33 kg average without differences between means. The highest weight gain at 15 and 30 days recorded in treatment T3, with means of 12.33 and 11.00 kg, respectively, existing statistical differences between treatments, the best body condition every 15 days was recorded in T3, with 3.7 to 3.70 at 15 and 120 days respectively which correspond to a desirable body condition degree. The protein content showed the best responses in the control group at 30 and 60 days with means of 3.73 and 3.51%, while at 90 days the best one was T3 with 3.52%. The highest benefit-cost was shown by T3 i.e. 1.44 USD. This is why it is recommended to use 400 mg lasolacid to improve the productive performance of cows.
