dc.description.abstract | Con el objetivo de observar el efecto del número de partos (NP) raza predominante (RP), época (EP) y condición corporal al parto (CCP) sobre la involución
uterina (IU), temprana ovulación silente (OS), el primer
celo posparto (PCPP) y los días vacíos (DV), en una finca ubicada en una zona de Bosque Seco tropical, se estudiaron 89 vacas, las cuales se clasificaron en
predominantes Carora (PCA) y otras predominancias
lecheras (OPR); primíparas y secundíparas, ordeñadas mecánicamente dos veces al día, sin becerro, alimentadas en pastizales con proteína 5,11%, suplementadas, con un concentrado 16,59% proteína y suero liquido de leche ad-libitum. Aparentemente sanas, no presentaron alteraciones clínicas al parto ni al posparto. La IU se completó a los 28 ± 7 dpp, la OS a
los 32 ± 9, el PCPP a los 72 ± 17 y DV a los 133 ± 40 dpp. No hubo efecto significativo de los factores sobre las variables IU, OS y PCPP, y fue significativo para DV los factores NP y EP. La producción láctea afectó significativamente (p<0.05) el modelo. | es_VE |

dc.description.abstract1 | (Anoestrus and open days in dairy cattle at the tropical zone) With the objective to study the effects of the factors parity (PA), breed
predominance (BP), season of year (SY) and body condition (BC) had on the uterine involution (UI), early silent ovulation (SO), first postpartum estrus (FPPE) and open days (OD) in a farm located in a dry tropical area, eighty-nine cows were studied, there were classified into Carora predominant breed (CPB) and another predominant dairy cows (APMB), heifers dams and secundíparas, there were non suckled and milked mechanically twice daily, grazed on grass land with 5.1% crude protein and concentrates with 16.59% of crude protein and liquid milk whey ad libitum. The cows were apparently health and did not have clinic abnormalities al parturition or after it. The UI was completed at 28 ± 7 ppd, the SO at 32 ± 9, the FPPE at 72 ± 17 and OD at 133 ± 40 ppd. Non significant effects of the studied factors on the UI,
SO and FPFE was observed and there were a significant effect of the PA and SY on the OP. The lineal model was significantly (p<0,05) affected by the accumulated milk production. | |
