From dry-off to 22 d before expected parturition
, all cows were fed the same far-off diet (net energy for lactation [[NE.sub.L]] 1.30 Mcal/kg dry matter [DM], Table 1).
Cows with one parturition
showed fat percentages weakly and positively correlated with milk yield in Indigenous zebus and Indigenous zebus by Guzerat (0.16 and 0.11, respectively) and negatively correlated in Indigenous Zebus by B.t.taurus and the High B.t.taurus group (-0.46 and -0.76, respectively).
Breeding criteria at foal heat were accepted as physiological parturition
process without abnormality, correct timing of placenta expulsion, no visible trauma at the vagina and perineum, no trace of infection, acceptable ultrasound and cytological examination results (Le Blanc, 2009).
With the exposed, the aim of this work was to evaluate the thermal comfort through natural and cooling ventilation over development, physiological parameters and thermal comfort indexes of lactating sows from first to third parturition
Thus, we predict that we will find no relationships between mammary functionality with litter size, litter birth weight, and parturition
In ruminants, the parturition
process usually occurs in non-steril conditions; thus, an indirect bacterial contamination of the genital tract is an expected episode .
Similar results by various authors in their respective studies (Fazzio et al., 2010; Hesari et al., 2012) in which copper injection to dams during their dry period resulted in significantly higher level of copper in dams and their calves, the possible cause for this increase could be due to the reason that supplementation of copper closer to parturition
time increases copper reserves of liver and blood.
We present the case of a 25-year old pregnant female who developed shortness of breath and fever 2 weeks prior to parturition
. The symptoms did not subside after her delivery, which was carried out via c-section.
Controlled drainage of fluid through the cervix should precede induction of parturition
, as sudden expulsion of large volumes of fetal fluids, sometimes in excess of 100-200L, results in hypotensive shock in the mare.
Infected cows will continue to shed bacteria through the vaginal fluid discharge until after parturition
when the discharge stops.
The aim of this work was to determine the dependency between polymorphism in the PIT-1 and fertility rates, body weight of cows and calves, the course of parturition
and viability of calves in Polish Black-and-White Holstein-Friesian cattle.
process is a complex phenomenon due to different factors that interact amongst themselves, (1) which can increase the risk of complications and death, and which additionally affect the mother's wellbeing.
