Efectos de la suplementación de zeolita en la salud e involución uterina y el retorno de la ciclicidad ovárica postparto en vacas lecheras del cantón Cuenca-Ecuador

Abstract

The clinoptilolite in the bovine diet acts as an antioxidant and alkalizing substance at the ruminal level, studies show that it works as an abductor of aflatoxins and helps strengthen the immune system indirectly. The objective of this study was to evaluate the action of zeolite in dairy cows in the postpartum period, and its effect on endometrial polymorphonuclear, calving-first service interval, calving-conception interval, ovarian cyclicity, uterine involution and accumulated production. A total of 60 mestizo cows (Holstein-friesian), multiparous, body condition between 2.5 - 3.5, clinically healthy; the diet offered was based in pastures more balaced; through randomized distribution two groups of 30 animals each were formed: control (GC) and treatment (GZ); GZ, consumed 50 and 200 g of zeolite, used from 15 to 60 days before and after delivery, respectively; were evaluated, at 34 to 47 days postpartum with endometrial cytology; In addition, the uterine involution (UI), ovarian cyclic reboot (OCR), interval calving first service (ICFS), calving-conception interval (CCI) and cumulative production (CP) at 100 days were assessed. The percentage of polymorphonuclear was lower (P <0.0001) in the GZ (2.89%). Meanwhile, the UI, OCR, ICFS, CCI and CP did not vary (P> 0.05) between treatments. In conclusion, the inclusion of zeolite in the bovine diet improved uterine health. Therefore, it can be adopted as a nutritional management strategy.
