“…It has been shown, however, that it may play a significant role in the digestion and absorption of starch in fast-growing broiler chickens 109 , 114 . Most of the undigested protein and fiber would undergo fermentation in the ceca and large intestine 115 , 116 .…”

Emus (Dromaius novaehollandiae), a large flightless omnivorous ratite, are farmed for their fat and meat. Emu fat can be rendered into oil for therapeutic and cosmetic use. They are capable of gaining a significant portion of its daily energy requirement from the digestion of plant fibre. Despite of its large body size and low metabolic rate, emus have a relatively simple gastroinstetinal (GI) tract with a short mean digesta retention time. However, little is known about the GI microbial diversity of emus. The objective of this study was to characterize the intraluminal intestinal bacterial community in the different segments of small intestine (duodenum, jejunum, and ileum) using pyrotag sequencing and compare that with the ceca. Gut content samples were collected from each of four adult emus (2 males, 2 females; 5–6 years old) that were free ranged but supplemented with a barley-alfalfa-canola based diet. We amplified the V3-V5 region of 16S rRNA gene to identify the bacterial community using Roche 454 Junior system. After quality trimming, a total of 165,585 sequence reads were obtained from different segments of the small intestine (SI). A total of 701 operational taxonomic units (OTUs) were identified in the different segments of small intestine. Firmicutes (14–99%) and Proteobacteria (0.5–76%) were the most predominant bacterial phyla in the small intestine. Based on species richness estimation (Chao1 index), the average number of estimated OTUs in the small intestinal compartments were 148 in Duodenum, 167 in Jejunum, and 85 in Ileum, respectively. Low number of core OTUs identified in each compartment of small intestine across individual birds (Duodenum: 13 OTUs, Jejunum: 2 OTUs, Ileum: 14 OTUs) indicated unique bacterial community in each bird. Moreover, only 2 OTUs (Escherichia and Sinobacteraceae) were identified as core bacteria along the whole small intestine. PICRUSt analysis has indicated that the detoxification of plant material and environmental chemicals seem to be performed by SI microbiota, especially those in the jejunum. The emu cecal microbiome has more genes than SI segments involving in protective or immune response to enteric pathogens. Microbial digestion and fermentation is mostly in the jejunum and ceca. This is the first study to characterize the microbiota of different compartments of the emu intestines via gut samples and not fecal samples. Results from this study allow us to further investigate the influence of the seasonal and physiological changes of intestinal microbiota on the nutrition of emus and indirectly influence the fatty acid composition of emu fat.

“…Apododermatite em frangos tem diversas causas, incluindo a condição do material da cama aviária, podendo ser levado em consideração o tamanho da partícula, manejo inadequado dos materiais de cama e excesso de umidade, afetando principalmente os coxins plantares e os joelhos das aves (NUNES et al, 2013). As incidências de lesões em frangos não são interessantes para a indústria devido às perdas econômicas.…”

RESUMOObjetivou-se avaliar a incidência de lesões de pododermatite no coxim plantar e joelhos de frangos de corte Cobb alojados em diferentes tipos de material de cama aviária em duas densidades de alojamento. Adotou-se o delineamento experimental inteiramente ao acaso, em um esquema fatorial 4 x 2 (quatro tipos de material de cama: areia lavada, maravalha, casca de arroz e feno de capim Tifton 85 triturado e duas taxas de lotação:10 e 14 aves/m2). Foram avaliadas as incidências de pododermatite nos joelhos (tibiotarso-metatarso) e coxim plantar de cinco aves por box aos 21, 28, 35 e 42 dias de criação. Aos 21 e 28 dias, não ocorreram lesões representativas nos joelhos, enquanto que o coxim plantar das aves alojadas em cama de feno apresentaram leves ulcerações. Aos 35 e 42 dias as lesões de joelho e coxim plantares foram mais leves nas aves alojadas em maravalha em comparação às criadas em cama de feno e de areia. Concluindo, frangos alojados em cama de maravalha apresentam menos lesões de pododermatite em comparação a frangos alojados em feno de Tifton e areia e a densidade de alojamento não tem influência sobre a incidência de pododermatite.Palavras-chave: Bem-estar animal, Cama de frango, Coxim plantar. Gallus domesticus, Taxa de lotação.
