Apparent digestibility and nutritional status of capuchin monkeys (Sapajus sp.) under human care.

BACKGROUND: Studing the nutritional needs and dietary habits of primates is essential to ensure their health and well-being. This includes the understanding of the use of nutrients and its correlation with health parameters. METHODS: Diet and nutritional parameters of 13 captive capuchin monkeys (Sapajus sp.) were assesed. Apparent digestibility of dry matter and nutrients were evaluated. Nutritional status was established based on body condition score (BCS) and muscle mass score (MMS). RESULTS: High apparent digestibility coefficients (ADC) were observed for crude protein and ether extract, but low for minerals and crude fiber. The ADC of EE and CF were related to MMS, and the biochemical parameters did not correlate with the AD coefficients obtained in the group. The nutritional status of the animals remained inadequate in 84.6% of the individuals, suggesting a reformulation of the diet and nutritional management.

Evaluation of the main disorders and microbiota of the oral cavity of capuchin monkeys (Sapajus apella) under human care.

BACKGROUND: Although critical to the overall condition of animals under human care, there is still limited information about oral health in neotropical primates. METHODS: We analyzed the main oral conditions and microbiota using mass spectrometry from 13 capuchin monkeys (Sapajus apella) under human care. The findings were registered on odontograms following the Triadan system. RESULTS: The most prevalent conditions were dental fractures (n = 9), mainly enamel fractures, and periodontal disease (n = 8), mainly grade 1 calculi. When exanimating teeth, alterations were identified in 90 out of the 416 evaluated pieces, being periodontal disease the most common (n = 60), followed by enamel fracture (n = 15) and missing teeth (n = 10). In the oral microbiota analyses, Staphylococcus and Streptococcus species were the most prevalent, although no obvious association was observed between isolated organisms and oral conditions. CONCLUSIONS: These findings hold the potential to prevent oral disorders, including fractures and periodontal diseases, contribute to molecular identification of oral microbiota, and to improve the well-being of primates under human care.

Food preference of nine-banded armadillo (Dasypus novemcinctus, Linnaeus, 1758) under human care.

This study aims to evaluate the food preference of nine banded armadillos kept in captivity, exposed to four different diets: Diet 1 (D1) - dry dog food and ground beef; Diet 2 (D2) - dry dog food, ground beef, and chicken eggs; Diet 3 (D3) - dog food, ground beef, bananas, and papaya; Diet 4 (D4) - dog food, ground beef, chicken eggs, banana, and papaya. To this end, an experiment was carried out for five weeks, the first four of which were for preliminary management and the fifth week for data collection. Frequency of consumption, total intake for each diet, and intake ratio were evaluated. The dietary preference was higher for the diets with a higher protein percentage (D1 and D2), mainly D2, which presented increased demand and intake starting on the fourth day of observation. In second day of observation, D1 presented the higher intake ratio, but D2 gradually replaced it. The diet containing the lowest protein rate (D3) was the least favored on all observation days and evaluations. In conclusion, the food preference of ex-situ armadillos seems to be related to the inclusion of greater amounts of protein, particularly that of animal origin, with eggs being the most appreciated ingredient in this study.
