Objective: To evaluate the effects of the carmine cochineal-resistant spineless cactus genotypes cv. Orelha de Elefante Mexicana (Opuntia) and Miúda (Nopalea) on the intake and digestibility of nutrients, ingestive behavior, performance, and ultrasound measurements of growing lambs. Methods: Thirty-six male (non-castrated) Santa Inês lambs were used, with an average age of 6 months and an initial average weight of 22.0±2.9 kg. They were distributed in a completely randomized design with 3 treatments (Tifton hay, Nopalea and Opuntia) and 12 replications, using initial weight as a covariate. The experimental period was 86 days, with the first 30 days used for the adaptation of the animals to the facilities, diets and management, and the remaining 56 days used for evaluation and data collection. Results: The intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), total carbohydrates (TC), non-fibrous carbohydrates (NFC), and total digestible nutrients (TDN) showed a significant difference (p<0.05) as a function of the diets, with the Nopalea treatment (p<0.05) increasing DM intake (g/kg and % body weight [BW]), CP, TDN, and TC digestibility, whereas the Tifton hay diet led to a high (p<0.001) neutral detergent fiber corrected for ash and protein (NDFap) g/d intake, NDFap (BW %) and digestibility of said nutrient. There was no effect of treatments (p>0.05) on feeding time, however, rumination time and total chewing time were higher (p<0.05) for animals fed Tifton hay. The performance of the animals was similar (p>0.05). For the ultrasound measurements, Nopalea promoted an increase in the final loin eye area, compared to Tifton hay. Conclusion: The use of spineless cactus variety Miúda leads to the greater intake and digestibility of nutrients. The evaluated carmine cochineal-resistant spineless cactus genotypes are alternatives for semi-arid regions as they do not negatively affect the performance of growing lambs.

Background/Aims: Despite the evidence of a modest to high prevalence of gastrointestinal (GI) symptoms in recreational runners and endurance athletes, the frequency and intensity of GI symptoms in exercisers, but nonathletes, individuals from different modalities have been less investigated. Therefore, the present study aimed to assess the prevalence of GI symptoms in individuals that practice moderate or vigorous physical exercise, at rest and during physical exercise training session. Methods: The sample consisted of 142 exercisers individuals (64 women and 78 men with mean age of 32.9±10.7 years). Out of the 142 participants, 71 reported to perform moderate physical exercise and 71 reported to perform vigorous physical exercise. Participants were assessed by an internet-based questionnaire designed to assess the frequency and intensity (at rest and during physical exercise training session) of 18 GI symptoms. Results: The GI symptoms most frequently reported by the respondents (during rest and physical exercise training session, respectively) were flatulence (90.8% and 69.7%), abdominal noise (77.5% and 41.5%), and eructation (73.9% and 52.1%). Overall, the frequency and intensity of symptoms were higher (P<0.050) during rest than physical exercise training session for who perform moderate and vigorous physical exercise. Conclusions: It can be concluded that GI symptoms in exercisers, but nonathletes, individuals are more prevalent during rest than during physical exercise training session, suggesting that moderate and vigorous physical exercise may act as a regulator of the GI tract.
