The importance of increasing animal production based on pastures has been discussed (Osechas and Becerra, 2009; Chacón, 2013). application management strategies in grasslands contributed to improving the quality quantity forage species used feeding animals with high nutritional requirements, such as dairy cattle (Perozo, 2011). This made it possible improve efficiency profitability livestock systems (Quintero et al., 2018). objective was characterize family farms Bocono municipality Trujillo...
Postpartum anestrus is the main reproductive problem that affects crossbred cattle production in Venezuela. (Soto et al., 2002 Theriogenology 57, 1503–1510; Soto 2000 Revista Científica FCV-LUZ 10, 391–398). In order to reduce postpartum and lower calving conception interval, 167 (Bos indicus×Bos taurus) anestrous cows between 90 130 days with body condition score 3 (scale 1–5) were randomly allotted one following treatments: 1) PH (n=59), intravaginal sponge (IS) impregnated 250mg of...
