in this experiment was routinely excellent
(rigid stand, good lock, and minimal backflow
of semen) and did not differ between
LUT and CONT groups (data not shown).
The last insemination occurred later after
weaning for LUT than for CONT (P <
.001), and fewer inseminations were performed
(P < .001). Farrowing rate was not
affected by treatment (P > .05). Total number
of pigs born (born alive plus stillborn)
and pigs born alive were higher (P < .01)
in LUT than in CONT, and average piglet
weight at day 3 after farrowing was independent
of treatment (P > .05) (Table 3).
