This study is an observational study that aimed to evaluate whether exposure to music in the final third of sows' gestation and during farrowing/lactation would change behavior, reduce stress, and improve reproductive rates. Forty-eight sows were used at 90 days of gestation until the weaning of their piglets. During gestation, sows were divided into two treatments: control and with music enrichment.

- - The study investigates how various environmental enrichment strategies affect the behavior of weaned pigs, using different groups that include both enriched and non-enriched settings.
- - Behavioral observations over 15 days revealed that pigs in non-enriched environments displayed more unwanted behaviors, while those with cognitive enrichment interacted more positively with their surroundings.
- - Alternating types of enrichment every 24 or 48 hours maintained the pigs' interest and reduced negative behaviors, indicating the importance of novelty in their environments.
The trial was conducted to evaluate the supplementation of E. coli phytase on performance, weight and ash of bones, as well as to determine the bioavailability of P and cost/benefit of its use in diets. A total 1,890 Cobb male day old chicks were assigned to six treatments and seven replicates with 45 birds each, distributed in a completely randomized design.
