Lactation education

Impact of the flavor of lactation diets on the performance of sows and litters

Maximizing the feed intake of lactating sows is important to improve litter growth performance and minimize sow weight loss. The performance of sows during lactation can be limited by feed consumption due to reduced appetite, especially in the early post-farrowing period. Many factors influence food intake, including environment and diet composition.

Increased diet palatability may increase feed intake during lactation. A feed additive developed by Adisseo (Krave AP) is formulated from a specific combination of natural and artificial flavoring compounds known to be attractive to pigs.

The objective of this study was to determine the effect of supplementation of the flavoring additive in sow lactation diets on sow feed consumption, sow weight and backfat change, and breeding performance. the scope. A total of 105 mixed-parity (DNA 241, Columbus, Nebraska) and litter (DNA 241 × 600) sows were used at the Kansas State University Swine Education and Research Center in four breeding groups. farrowing in batches. On day 110 of gestation, the sows were moved to the farrowing house. At this time, back fat, caliber and weight were all recorded. Sows were fed either a standard corn-soya lactation diet or the standard corn-soya lactation diet with 0.05% added food flavor (Krave AP, Adisseo, Alpharetta, Georgia) at the expense of maize. Sows received six pounds of feed from day 110 of gestation until farrowing, then had ad libitum access to feed during lactation.

This trial was conducted during the transition to the new farrowing house at the KSU Swine Education and Research Center. Therefore, sow groups 1 and 2 farrowed during the summer months in the old barn which had a regulated environment, using fans and drip coolers to account for sow comfort. Groups 3 and 4 whelped in the new maternity unit during the winter months which used cold cells to maintain target temperatures. The mean temperature in the maternity ward for groups 1 and 2 was 82.1°F and for groups 3 and 4 was 74.5°F.

Overall, sows fed the food flavor ration tended to have higher feed consumption from farrowing to day 10, from farrowing to weaning, and throughout lactation. However, the response was greatest during the summer months when sows had lower overall feed intakes.

Piglets from sows fed the flavored diet had a higher ADG from day 2 to weaning and average piglet body weight at day 10 and weaning during the summer months, but the reverse was observed in litters during the winter months. There was no overall impact of feed flavor on piglet survivability.

A group of piglets were tracked into the nursery from the summer farrowing group, and pigs from sows fed the flavor diet had a weaning weight 1 lb heavier and finished the nursery with 2 pounds more than piglets from sows fed the control diet. No differences were found for sow body weight change, sow back fat change or sow thickness score change between entry and weaning. The weaning-oestrus interval was also analyzed, but no difference was found between treatments.

In conclusion, sows fed the flavor diet tended to have higher overall ADFI and higher piglet weaning weight. In this study, the addition of the feed additive in sow lactation had a greater impact on ADFI and litter performance during the hottest summer months, when feed intake is depressed. Differences in feed flavor response between the two seasons and environments indicate that inclusion of the additive in the lactation diet in situations where sow intake is low may result in improved sow performance. and scope.
