A utilização de subprodutos e resíduos de frutas na suplementação de ovinos tem-se demonstrado uma importante alternativa sustentável, sendo capaz, de minimizar os danos ambientais e ao mesmo tempo diminuir o custo de produção aos proprietários. Diversos aspectos, como digestibilidade, comportamento ingestivo, características de carcaça, desempenho, dentre outros, estão sendo avaliados quanto à inclusão de resíduos e subprodutos de frutas na suplementação ovina. Apesar de sua grande relevância, são poucos os estudos abordando esta temática, sugerindo-se novas pesquisas quanto a esse aspecto
sUMMAryThis study evaluated the performance and mortality of piglets from birth to weaning undergoing a diet supplemented with coconut oil, as well as performed the environmental characterization of facilities. The experiment was carried out using pig maternity facilities. The experimental design consisted of a completely randomized block design with two treatments, eight blocks and twelve piglets per experimental unit. The supplemented piglets received 12 ml of coconut oil. Piglets creeps provided stable conditions in the hottest hours of the day for the stalls. The relative humidity remained below the optimal levels for pigs at the hottest times of the day; BGTHI was appropriate for the recommendation of thermal comfort. No effect (p>0.05) of the supplementation with coconut oil on the average daily gain weight of (g/day) of piglets until weaning was reported and the values obtained were 227 g/day and 228 g/day, without the use and the use of coconut oil, respectively. The mortality rate of supplemented piglets 1.66 % and those who did not receive supplementation 5%, showed the importance of coconut oil when taking the production of piglets per sow into consideration.Suplementação com óleo de coco para leitões até o desmame resUMo Objetivou-se avaliar o desempenho e mortalidade de leitões do nascimento à desmama submetidos a dieta suplementada com óleo de coco, bem como realizar a caracterização ambiental das instalações. O experimento foi realizado utilizando instalações suinícolas de maternidade. O delineamento experimental foi em blocos inteiramente casualizados, com 2 tratamentos, oito blocos e doze leitões por unidade experimental. Os leitões que foram suplementados receberam 12 ml de óleo de coco. Os escamoteadores proporcionaram condições estáveis nas horas mais quentes do dia, em relação às baias. A umidade relativa do ar permaneceu abaixo dos patamares ideais para os suínos nos horários mais quentes do dia; o ITGU esteve apropriado na recomendação do conforto térmico. Foi verificado que não houve efeito (p>0,05) do uso de suplementação com óleo de coco sobre o ganho de peso médio diário (g/dia) dos leitões até o desmame, os valores alcançados foram 227 g/dia e 228 g/dia, sem o uso e com o uso de óleo de coco respetivamente. A taxa de mortalidade dos leitões suplementados foi de 1,66% e aqueles que não receberam a suplementação foi de 5%, mostrando a importância do óleo de coco quando se leva em consideração a produção de leitões por matriz.

The objective of this study was to describe emus’ breeding performance in Brazil at different ages, grouped in couples or colonies. The duration of the breeding season and the production of eggs per female housed were recorded, and the productivity and breeding variables were associated with the variation of the photoperiod. The total production of the flock was 180 eggs, and the breeding season lasted 167 days (April-September), a period with an average of 11 h and 11min of daylight. The breeding season lasted 113, 133 and 82 days, the numbers of eggs produced per female were 7.29, 25.67 and 17.3, and productivity values were 31.6, 38.6, and 45.4% in the groups of birds with ages of two, four and seven years, respectively. The breeding season in 2016 occurred between April and August in Brazil. Older birds tended to start breeding later. The production rate observations indicated that earlier peak production was associated with lower egg production potential. Finally, there was a tendency for better breeding performance of birds housed in couples than in groups with more birds.
