“…The use of feed flavors to increase feed intake has been variable in all production phases ( McLaughlin et al, 1983 ). Silva et al ( 2018 , 2021 ) conducted two studies in tropical climates evaluating the same lactation feed flavor tested in our trial and observed similar outcomes to the summer portion of our study, including an increase in sow ADFI and piglet ADG. Other trials using different feed flavors have also observed similar responses ( He et al, 2017 ; Wang et al, 2021 ).…”

“…This association with increased sow feed intake and increased piglet and litter weight and ADG is expected ( Koketsu et al, 1996 ; Eissen et al, 2003 ) and is the result of increased milk production which is the biggest factor for increased preweaning piglet growth ( Solà-Oriol and Gasa, 2017 ). Counter to our observations, Silva et al (2021) conducted a study in two different environmental conditions, defined as hot and cool, and concluded that the addition of a feed flavor in the sow lactation diet could increase sow feed intake regardless of temperature. Silva et al (2018) observed that as the concentration of flavor (Krave AP; Adisseo) increased in the diet from 0.025% to 0.05%, feed intake increased, with sows fed with the 0.05% flavor diet having greater intake than sows fed with the control diet, with sows fed with 0.025% fed flavor being intermediate.…”

“…Feed flavors can stimulate feed intake by using enhanced taste and smell ( Roura et al, 2008 ). The use of feed flavors in the sow lactation diet has been found to increase lactation feed intake, leading to increased milk production and litter weight gain when sows were housed in a tropical, humid environment ( Silva et al, 2021 ). However, in other trials, no differences in feed intake were observed when a feed flavor was used in lactation diets ( Charal et al, 2016 ).…”

A total of 105 sows (Line 241, DNA, Columbus, NE) were used across four batch farrowing groups to evaluate the effects of feeding a feed flavor in lactation diets on sow and litter performance. Sow groups 1 and 2 farrowed in an old farrowing facility during the summer months and groups 3 and 4 farrowed in a new farrowing facility during the winter months. Sows were blocked by body weight (BW) within parity on d 110 of gestation and allotted to 1 of 2 dietary treatments. Dietary treatments were a standard corn-soy-based lactation diet (control) or the control diet with the addition of a feed flavor at 0.05% of diet (Krave AP, Adisseo, Alpharetta, GA, USA). Farrowing facility environment had a large impact and resulted in many interactions with the feed flavor treatment. From farrowing to weaning, sows fed the feed flavor in the old farrowing house tended to have a higher (P = 0.058) lactation feed intake, while no difference in ADFI was observed in the new farrowing house. Pigs weaned from sows fed the feed flavor in the old farrowing facility had a higher (P = 0.026) BW at weaning and piglet average daily gain (ADG) from d 2 to weaning (P = 0.001) compared to piglets from sows not fed the feed flavor; whereas the opposite occurred in the new farrowing house. Progeny from one farrowing group in the old farrowing facility was followed into the nursery. A total of 360 weaned pigs (DNA 241 × 600: initially 5.7 kg) were used in a 2 × 2 factorial in the nursery portion of the study to evaluate the effects of previous sow feed flavoring treatment (control vs flavor) and nursery diets formulated with or without a feed flavor on growth performance in a 38-d trial. Nursery treatments were either a control diet or a diet containing a feed flavor (Delistart #NA 21, Adisseo, Alpharetta, GA, USA). Offspring from sows fed the flavor diet were heavier at weaning (P < 0.001) which was maintained throughout the study. Overall, progeny from sows fed a diet containing a feed flavor had greater (P < 0.05) ADG, ADFI, and final BW during the trial. The presence of a feed flavor in the nursery did not improve overall nursery performance. In conclusion, when sow lactation feed intake was increased in the old farrowing house, pigs weaned from sows fed the flavor diet were heavier (P = 0.039) at weaning compared to pigs weaned from sows fed the control diet. Adding the feed flavor increased sow feed intake and piglet ADG in a warm environment, but not in a cool environment.

“…Similarly, Ribeiro et al (2018), in a meta-analytic study, found that for every 1 °C increase in ambient temperature above thermal comfort (25 °C), there is a reduction in feed intake, milk production, and piglet weight at weaning. Silva et al (2021) confirmed that under tropical conditions, high ambient temperatures (26.2 °C) have an impact on performance, voluntary feed intake, and feeding behavior of lactating sows.…”

The objective of the present study was to evaluate the effects of cooling systems by negative pressure versus directed ducts on the performance of lactating sows and their litter. The experiment was conducted in a tropical climatic region in Brazil. Ninety-four lactating sows during 26.2±1.7 days of lactation were included with their 1,236 piglets. Sows were distributed using a completely randomized block design into two treatments: a negative pressure cooling (NPC) system and a directed duct cooling (DDC) system. We adopted sow parity as blocking criterion. During the experimental period, environmental temperatures inside the farrowing rooms were 22.9±1.5 and 25.4±2.5 °C, respectively, using the NPC and DDC systems. Sow daily feed intake, litter weight at weaning, piglet weight at weaning, litter daily weight gain, piglet daily gain, and daily milk production per sow were greater in the NPC system than in the DDC system. The type of cooling system did not affect piglet weight after standardization, mortality, number of piglets weaned per sow, and estrus return. The use of an NPC system can reduce the effects of higher environmental temperatures better than the DDC system. The NPC system allowed for greater feed intake, piglet and litter weight gain, weight of piglets and litter at weaning, and milk production compared with the DDC system.

“…Sow FI during lactation can be highly variable, not only sow-to-sow but also temporarily as the lactation period progresses ( O’Grady et al, 1985 ). On average, sows should eat approximately 5.6 kg/d during a 3-week period ( NRC, 2012 ), yet intake can be limited severely during the first few days after farrowing, and it can reach up to 9 kg/d by mid-lactation ( Silva et al, 2021 ). Results from this study showed greater variation in the individual intake of sows fed the higher density diet with 3% added fat, whereas reducing energy density improved within-treatment uniformity of FI.…”

Sow productivity improvements are associated with high energetic demand due to increasing prolificity. The reproductive life and longevity of sows, and the readiness for weaning of the offspring may be impaired when sows loose significant body weight (BW) during lactation. The impact of a multicarbohydrase containing α-galactosidase on a low energy dense lactation diet was evaluated in this study. Two-hundred and eight sows (218 ± 25.2kg) were blocked by parity and BW to one of 4 treatments, in which a corn-soybean meal diet was formulated to have varying levels of added fat (0, 1.5% and 3%) to titrate an energy density model. A fourth treatment replicated the 0% added fat formulation with enzyme supplementation at 250 g/tonne. Sows were weighed individually on entry, post-farrow (by calculation) and at weaning. Daily feed intakes (ADFI) and caloric intake were used for calculation of sow feed efficiency (FE) and caloric efficiency. Litter performance was characterized at birth, and size was standardized within 24h of farrow and within treatment to ensure uniform litter sizes. Average wean weight and pre-weaning mortality were determined. Piglets were weighted individually to study litter weight distribution. Data was analyzed as a randomized completely block design, using sow as the experimental unit, treatment as the main effect, and standardized average weight and litter sizes as covariates where appropriate. Although sows fed a multicarbohydrase had lower standardized litter size (P < 0.001), average wean weight was higher in this group and equivalent to the 3% added fat treatment. Enzyme supplementation tended to reduce the proportion of light weight pigs (BW < 4.1kg) within the litter, when compared with the 0% added fat diet (P < 0.1). The multicarbohydrase tended to increased sow ADFI (P < 0.10), although sows from all treatments had equivalent caloric intakes during lactation (P > 0.1). Enzyme supplementation yielded significant improvements in sow FE (P < 0.01), similar to the 3% added fat group. Thus, the carbohydrase degrading enzyme tested in this study improved the efficiency of sows, while increasing average wean weights of the offspring, suggesting an improvement in nutrient digestion and/or metabolic efficiency from typical lactation diets.
