The aim of this study was to assess the nutritional value of diets that contain torula yeast in rabbits and agoutis and the influence of torula yeast on the apparent digestibility of the nutrients. In the first experiment, 32 New Zealand White rabbits were fed diets with four different levels (0%, 5%, 10%, and 15%) of torula yeast that was substituted for soybean meal. The experimental design was completely randomized with four treatments and eight repetitions. The digestibility coefficients (DC) of dry matter (DM; DCDM), crude protein (DCCP), neutral detergent fiber (DDNDF), ether extract (DCEE), and gross energy (DCGE), as well as the mean daily consumption (MDC), were calculated (MDC: 113.98, 113.96, 113.22, and 115.07 ResumoObjetivou-se a avaliação nutricional das dietas com a inclusão de levedura torula para coelhos e cutias e sua influência sobre a digestibilidade aparente dos nutrientes. No primeiro experimento, utilizou-se 32 coelhos Nova Zelândia Branco. Avaliou-se quatro níveis de inclusão (0, 5, 10 e 15 %) de torula em substituição ao farelo de soja. O delineamento empregado foi inteiramente casualizado, com quatro tratamentos e oito repetições. Determinaram-se os coeficientes de digestibilidade (CD) da matéria seca (CDMS), da proteína bruta (CDPB), da fibra detergente neutro (CDFDN), do extrato etéreo (CDEE) e da energia bruta (CDEB) das dietas, bem como os valores de energia e proteína digestíveis da torula. Foram obtidos os valores de digestibilidade para CDMS (71,04; 69,98; 67,79 e 74,08 %), CDPB (80,17; 79,55; 75,10 e 78,47 %), CDFDN (66,85; 65,50; 63,31 e 70,12 %), CDEE (77,83; 76,46; 78,36

This study aimed to describe the main behaviors of white-lipped peccaries (Tayassu pecari) expressed in a semi-intensive production system in Brazil. The behavioral activities of two groups of peccaries allocated in two paddocks were assessed, totaling 17 adult animals and eventual pups in different developmental stages. The animals were visually observed using the ad libitum sampling and scan sample methods during the adaptation and experimental phases, respectively. The animals were evaluated in the morning, afternoon, and at night. The behavioral activities observed by ad libitum sampling comprised feeding, pool contact, moving, staying inside the handling area, resting, mud bathing, mutual rubbing, rubbing, aggression, sexual behavior, copulation, foraging, breastfeeding, sleeping, territorial marking, interactions, birthing, gnawing, and other behaviors. All behaviors observed by the ad libitum sampling method were confirmed in the experimental period by scan sample, except for territorial marking and birthing. The effects of time of day were statistically significant (p <0.05) for eating, pool contact, movement, staying inside the handling area, resting, mud bathing and sleeping. These results contribute to the understanding of instinctive animal habits and to the development of nutritional, environmental and health management protocols that meet the requirements of peccaries.
