In Exp. 1, 50 sows and their litters were used to determine the effects of adding a feed flavor to the creep diet on the proportion of pigs consuming creep feed ("eaters") and preweaning performance. Sows were blocked according to parity and date of farrowing and allotted to 2 experimental treatments: 1) litters fed a creep diet with no flavor (negative control) or 2) negative control diet with the feed flavor (Luctarom) included at 1,500 mg/kg. Both creep diets contained 1.0% chromic oxide and were offered ad libitum from d 18 until weaning at d 21. Adding flavor to the creep diet did not (P > 0.41) affect weaning weights, total BW gain, ADG, total creep feed intake, daily creep feed intake, or the proportion of creep feed eaters in whole litters. In Exp. 2, 480 weanling pigs (6.58 ± 0.41 kg; 20 ± 2 d) from Exp. 1 were randomly selected by preweaning treatment group, blocked by initial BW, and allotted to 1 of 8 treatments in a randomized complete block design to determine the interactive effects of preweaning exposure to flavor (exposed vs. unexposed), nursery diet complexity (complex vs. simple), and flavor addition to nursery diets (with vs. without flavor). Each treatment had 10 replications (pens) with 6 pigs per pen. Diets with flavor were supplemented with the flavor at 1,500 mg/kg in phase 1 diets and 1,000 mg/kg in phase 2 diets. A tendency for a 3-way interaction for ADG from d 5 to 10 (P = 0.10), 10 to 28 (P = 0.09), and 0 to 28 (P = 0.06) was observed. Postweaning ADG of pigs exposed to flavor in creep feed and fed flavored complex diets in the nursery was greater than pigs in any other treatment combination. Increasing diet complexity improved (P < 0.01) ADG and ADFI during both postweaning phases. Adding flavor to creep feed had no effect on G:F (P > 0.34) and pig BW (P > 0.45) in both postweaning periods. Adding flavor to starter diets tended to improve ADFI (P = 0.06) during d 0 to 5. In conclusion, adding flavor to the creep feed did not affect litter creep feed intake, the proportion of piglets consuming creep feed, or preweaning performance when creep was provided for 3 d before weaning. Preweaning exposure to feed flavor improved postweaning ADG in pigs fed complex diets supplemented with the same flavor but did not influence performance of pigs fed simple diets. |
