Lactating sows and their litters are particularly vulnerable to heat stress (HS). HS decreases fertility, feed intake, milk production, and litter growth of sows. Approaches are needed to mitigate the negative effects of HS on animal welfare and oxidative damage to tissues.

The study was arranged as a 2 × 2 × 6 factorial design with two dietary substrates, two time points (6 and 24 h), and six treatments. The treatments included a control group with no MOS or OP administration and groups administered with 2% of a mixture containing MOS and OP in the following ratios: 1:0 (MOS), 0:1 (OP), 1:1 (MOS:OP), 1:2 (MOS:2OP), and 1:3 (MOS:3OP).

Botanical extracts (BE; Apex, Adisseo North America, Atlanta, GA) are known to enhance DMI and gut health, whereas direct-fed microbials (DFM), such as a Lactobacillus acidophilus fermentation product (EX: Excel; Pacer Technology Inc., Murtaugh, ID), have demonstrated improved gut health and growth performance when fed to growing neonatal Holstein calves. The hypothesis was this combination may be synergistic to neonatal calf growth performance and intestinal health.
