Exempel på calve

• The effect of infections at calving on production in the subsequent lactation was not examined.

• An interaction between season of calving and nutrition on the resumption of ovarian cycles in post-partum beef cattle.

• Similarly, calving difficulty whose determinants can be variable was not taken into account in the model.

• An indicator of length of calving season was measured by the date by which approximately 75 % of calves were born.

• Samples were missing at calving for 32 quarters.

• The event of calving appeared to reduce the likelihood of shedding.

• At 1 week post-partum, 13\52 (25 %) calves born in 1997 were shedding the organism.

• The reduced levels of kairomones in calf odour accord with the finding that calves attract significantly fewer tsetse than an ox.

• Several studies showed a negative correlation of the postpartum anoestrus with the calving date on suckler herds in both the northern and southern hemisphere.

• Effects of precalving feed level on birth weight, calving difficulty and subsequent fertility.

• The two other models were comparable in all terms except they added a predictive variable to take into account the effect of calving date.

• Cumulative impacts of an evolving oilfield complex on the distribution of calving caribou.

• For the decline-of-maternal-antibody analysis, calves with maternal antibody that subsequently sero-converted before maternal-antibody had declined were considered as withdrawals (censored).

• Clearly, shorter calving intervals, even with constant lactation yields, would lead to larger lifetime milk yields.

• The detection of new infections in animals at calving observed in our study is probably the result of infections that occurred during the non-lactating period.
