Effect of nutraceutical supplementation on semen quality in stallions [PDF]
Background The use of reproductive biotechnologies in equine practice has shown that some stallions are subfertile, so ways to improve fertility have been sought.

Intermittent versus continuous drought: chlorophyll a fluorescence reveals photosystem resilience in tomato [PDF]
IntroductionRecurrent drought threatens Mediterranean tomato yields, yet how the time-scale of drought shapes photochemical tolerance remains unclear.MethodsWe evaluated six genotypes, three commercial cultivars (‘Sintonía’, ‘Marejada’, ‘Valenciano’) and

A Circular Economy Approach to Integrate Divergent Ruminant Production Systems: Using Dairy Cow Feed Leftovers to Enhance the Out-of-Season Reproductive Performance in Goats [PDF]
Based on a circular economy approach, we evaluated the possible effect of targeted supplementation with leftover feed from dairy cows (i.e., intensive system) on the reproductive performance of crossbred/rangeland goats (i.e., extensive system) in arid ...
