“…More opportunity for locomotion may also be advantageous, because exercise during the final 6 wk before parturition results in improved ease of calving and earlier release of the placenta (Lamb et al, 1979). Similar results are reported in sows (Hale et al, 1981;Ferket and Hacker, 1985) as well as in humans (Clapp, 1990;Prather et al, 2012).…”

The present study investigated how calving behavior and calf vitality in Holstein and Jersey dairy cows were affected by housing during the final 4 wk precalving. One hundred twenty-one cows (36 primiparous and 85 multiparous) were moved either to a group pen with deep straw bedding or into freestall housing 4 wk before the expected calving date. Individual straw-bedded maternity pens were placed adjacent to the straw-bedded group pens, and cows were moved to the maternity pens before calving. Cows that spent more than 12 h in the maternity pen before calving and calved unassisted were included in this study (39 multiparous cows and 15 primiparous cows). Dams were observed from 6 h before calving until 6 h after calving. The time from the onset of rhythmical abdominal contractions (defined as the onset of stage II labor), the time from a visible amniotic sac, and the time from visible calf feet until the birth of the calf were recorded. Furthermore, the cows' latency to stand up after birth was recorded. Calves were observed during the first 6 h after birth and the latency to first standing attempt, to first successful standing, to first suckle attempt, and to first successful suckling were recorded. Cows previously housed in straw pens expelled the calf faster once the calves' feet were visible compared with cows previously housed in freestalls. Multiparous cows stood sooner and licked their calf sooner after birth compared with primiparous cows. Jersey calves of cows previously housed in straw pens also stood up and suckled their dams sooner compared with Jersey calves of cows previously housed in freestalls. Holstein cows previously housed in straw pens tended to stand up sooner compared with Holstein cows previously housed in freestalls. These results suggest that a longer period of housing on deep-bedded straw compared with freestalls with mattresses before calving may facilitate the calving process, whereas the effect on calf vitality needs further investigation.

“…In trial 1, the exercised gilts walked 15 min daily on the treadmill at 0 slope and a speed of 2.6 km/h, while gilts in trial 2 walked 30 min daily on the treadmill at the same slope and speed. These animals were conditioned to the treadmill by exercising 5 min/d for the first 6 d. The treadmill has been described in detail in a previous report (Hale et al, 1981).…”

Littermate gilts were used to study the effects of exercise during the growing-finishing period on performance, age at puberty and conception rate. In trial 1, 12 gilts walked 15 min daily on a treadmill 6 d/wk (Monday through Saturday) until they attained body weights of about 100 kg, while 12 littermate gilts were not forced to exercise. Initial weight and age averaged 24.7 kg and 74 d, respectively. For trial 2, 12 gilts walked 30 min daily 6 d/wk (Monday through Saturday) on a treadmill, while 12 littermate gilts were not exercised. Initial weight and age of these gilts averaged 26.8 kg and 76 d, respectively. The treadmill was operated at 0 slope and at a speed of 2.6 km/h. Within trial, there were no differences (P greater than .05) in weight gain, average daily gain, feed consumed, feed to gain ratio, average backfat depth of loin eye area between gilts exercised and those not exercised. In both trials, there were no differences (P greater than .05) in age at puberty between exercised and nonexercised gilts. In trial 2, 10 gilts were selected in each of the exercised and nonexercised groups and were hand-mated to the same boar on the second estrous cycle. Eight gilts from the exercised group conceived, while nine from the nonexercised group conceived. Four gilts from the nonexercised groups had severe locomotor problems while only one gilt from the exercised groups had difficulty walking.
