Five alternative models were applied for analysis of dystocia and stillbirth in first and second parities. Models 1 and 2 were included only to estimate the parameters required for model 4, and models 3 and 5 are included only as comparisons to the model 4 estimates. Variance components were estimated by multi-trait REML, including cows with valid calving records for both parities. For the effe...

Some young large farm animals show a laminar bone formation in the long-bone cortex. Such a laminar bone is gradually replaced by Haversian bone with osteons during their growth periods. In this preliminary study, we observed the transverse ground samples of tibia cortex in young calves, pigs, and sheep by backscattered electron imaging. The cortex bones of all the newborn (NB) animals were bas...

Opening of the pre-orbital gland in red deer (Cervus elaphus) was previously found to be associated with feeding and negatively associated with achieving satiety in bottle-reared red deer calves. We speculated that this acted as a signal from a calf to the mother that it was hungry. Thus, we focused on a possible association between the pre-orbital gland opening and the sucking behavior in red ...
