Effect of heat stress on tonic and GnRH-induced gonadotrophin secretion in relation to concentration of oestradiol in plasma of cyclic cows. Effects of acute and seasonal heat stress on tonic and GnRH-induced LH and FSH secretion were examined during the early follicular phase of the oestrous cy...

Factors affecting milk ejection and removal during milking and suckling of dairy cows The release of oxytocin and milk ejection occurrence in response to teat stimulation are crucial for fast and complete milk removal during milking or suckl... V. Tančin,R.M. Bruckmaier - 《Veterinární Med...
By d 30, after three infusions, all FMTrt cows had terminated their pregnancies; however, CON cows maintained their pregnancies. Perhaps, these data indicate the importance of prostaglandins during this critical period of pregnancy. Further research is required to fully under...
(P≤0.05)to a greater extent from mid-supplementation to calving for PUFA compared with CON cows.Cow plasma C20:0,C20:5n-3,and C22:6n-3 were increased(P≤0.01)in PUFA during supplementation period.At birth,PUFA steers had greater(P=0.01)plasma C20:5n-3.No differences(P≥0.33)were ...
While many farmers considered it unethical to slaughter pregnant cows without a good reason for doing so, many dairy farmers identified animal welfare as an important parameter in the decision, which was typically when the general condition of the cow or heifer would make it difficult...
Vitamin or trace element supplementation did not differ with the control group in both the prepartum and postpartum period for immune variables. There, however, was greater phagocytosis in cows supplemented with vitamin and trace elements during the prepartum period that might be related to ...
In cows, the relative percentage of CD8(+) cells after MRL in the presence of IFN-tau was significantly lower than in heifers. Differential effect of rIFN-tau on proliferation and lymphocyte subsets distribution in a one-way MRL in cows and heifers indicated that the age of the mother is...
