First, let’s restate the question and the available choices to set the stage for evaluation.
Question: What is a potential benefit of adding dietary fiber to gestating sow rations?
Answer options:
- Decreased reproductive performance
- Increased stereotypic behaviour
- Decreased feed costs
- Improved lactation feed intake

Now, examine each option in turn:
Option 1: Decreased reproductive performance
This claim suggests that adding fiber would harm reproduction. In most agricultural nutrition contexts, fiber is used to modulate gut health, satiety, and intestinal function without inherently driving down reproductive metrics. Unless fiber is added inappropriately (e.g., at very imbalanced frequency or crystallized forms that disrupt energy intake), this option presents a negative outcome that contradicts the idea of a potential benefit.
Option 2: Increased stereotypic behaviour
Stereotypies are repetitive, purposeless behaviors often linked to stress or confinement and poor welfare. Adding dietary fiber is not typically associated with increasing such behaviours; in fact, well-formulated fiber can improve gut health and satiety, potentially reducing stress-related behaviors. Therefore, this option mischaracterizes the welfare impact and is unlikely to be a benefit.
Option 3: Decreased feed costs
Fiber-rich ingredients can sometimes be cheaper than energy-dense alternatives, but this outcome is highly context-dependent. In gestating sows, the primary goals of fiber inclusion are often satiety, gut health, and metabolic stability, not necessarily overall feed cost reduction. Without specifics on ingredient prices and formulation, this option remains uncertain as a general benefit and is not the most direct positive effect associated with fiber in gestation.
Option 4: Improved lactation feed intake
A plausible benefit of dietary fiber is improved gastrointestinal health, better satiety signaling, and stabilized energy intake during gestation, which can translate into improved feed intake capacity and subsequently better lactation performance after farrowing. This aligns with known nutritional strategies where fiber can support gut function and energy balance, potentially yielding improved lactation feed intake as a downstream outcome.

In summary, the reasoning points toward option 4 as the most coherent potential benefit: dietary fiber can support gut health and energy balance in gestating sows, which may enhance lactation-related feed intake after parturition. The other options describe unfavorable or uncertain outcomes that are not typically framed as benefits of fiber inclusion in gestating sow diets.
