“…Aliás, estas observações não se afastam daquelas assinaladas por Camiruaga e Simonetti (2003) como ausência de vesícula biliar e intestino grosso mais extenso que o intestino delgado. Um exemplo digno de nota é a ausência de inglúvio, cuja função passa a ser exercida pelo proventriculo gástrico e ventrículo gástrico (Angel, 1996;Camiruaga e Simonetti, 2003), cujas cavidades são quase simultâneas.…”

ResumoAspectos histológicos do trato gastrintestinal do avestruz (Struthio camelus) são pouco estudados, portanto, é de interesse desta pesquisa ampliar tais estudos. Para isso foram obtidas amostras de diferentes segmentos do tubo digestório de cinco avestruzes jovens, com idade entre 20 a 30 dias. Com base nos resultados obtidos pudemos concluir que os diferentes segmentos do tubo digestório do avestruz jovem apresenta a mesma estrutura geral de outras aves e mamíferos domésticos, com pequenas diferenças, como ausência de inglúvio e vesícula biliar, intestino grosso maior que o intestino delgado e ceco com propriedades fisiológicas semelhantes ao estômago de ruminantes. Estas variações são inerentes à espécie ou podem ser decorrentes da idade e hábito alimentar. Esperamos que esta análise contribua para uma melhor compreensão dos processos fisiológicos relacionados à nutrição e ao manejo do avestruz durante seu crescimento. Unitermos: avestruz, histologia, trato gastrintestinal Abstract Histological analysis of the gastrointestinal tracts of young ostriches (Struthio camelus).The histological aspects of the gastrointestinal tract of the ostrich (Struthio camelus) have been little studied, so this research is focused on such analysis. To this end, samples were obtained from different segments of the digestive tubes of five young ostriches aged 20 to 30 days. Based on the results, the authors conclude that the different segments of the digestive tube of the young ostrich presents the same general structure as that of other domestic birds and mammals, with some differences that may be due to age, the species involved, or feeding habits. It is hopes that this analysis will contribute to a better understanding of the physiological processes related to the nutrition and management of ostriches during their growth.

“…Ostriches have a different gastrointestinal tract compared to broilers, which allows them to digest dietary fibre more efficiently (Cilliers et al, 1992(Cilliers et al, , 1997Brand et al, 2000;Sales, 2006). The length of the colon in an adult ostrich represents approximately 57% of the intestines compared to only 3% in an adult broiler (Angel, 1996). This may explain the higher apparent metabolizable energy of feed ingredients in adult ostriches compared to cockerels (e.g.…”

“…The commercial probiotics were selected based on their difference in microbiota composition and in previous studies done in both broilers (Kabir et al, 2004;Gunal et al, 2006;Mutus et al, 2006;Nayebpor et al, 2007;Paryad & Mahmoudi, 2008;Boostani et al, 2013) and ostriches (Hasan-Rezaie et al, 2013). A basal diet was formulated based on the nutritional recommendations reported in previous studies of ostrich nutrition (Angel, 1996;Cilliers et al, 1998). The diet (Table 1), used as the basal diet throughout the experimental period, was either unsupplemented (i.e.…”

This study was undertaken to determine the effect of four commercial probiotics on growth, body characteristics and haematological parameters of ostrich chicks. A total of 25 ostrich chicks (937±68.1 g) were individually allocated and fed the experimental diet for six weeks (n=5 per treatment). Experimental diets consisted of a corn/soybean meal-based diet unsupplemented (T1: Control), and four diets supplemented with probiotics according to the recommendations of the manufacturer (T2: 0.04% Bioplus 2B; T3: 0.09% Primalac; T4: 0.1% Thepax; and T5: 0.03% Protexin). Feed intake (FI), body weight (BW) and seven body characteristics (e.g. height) were measured every week. Blood samples and other body characteristics were also taken in the last week. There was an interaction effect between diet and time on all the growth variables and body characteristics (p<0.05). Both the BW and the BW gain of the ostrich chicks were, in general, higher for those fed the diet T2 than those fed the control diet (0.42, 1.07, 0.99, 1.09, 2.51, and 1.66 kg BW gain vs 0.28, 0.41, 0.83, 0.94, 1.15, and 1.15 kg BW gain at 7, 14, 21, 28, 35, and 42 days respectively), while for those fed the other diets containing probiotics differences were only observed at 42 days (p<0.05). Consuming probiotics over an extended period influenced several of the haematological parameters differently compared to those fed the control diet (p<0.05). T2 and T3 increased the concentration of total cholesterol (157 and 210 mg/dL respectively), when compared to those fed the control diet (119 mg/dL), while total cholesterol was slightly reduced (p>0.05) for those fed the diet containing Thepax (T4, 79 mg/ dL). In conclusion, the effects of commercial probiotics on growth performance, body characteristics and haematological parameters varied among probiotics.

“…In 1996, information on the nutrient requirements for growing ostriches was limited (Angel, 1996) and the requirements estimated were based on other poultry species. Numerous scientific studies have been conducted since then to gain more knowledge on the subject and permit more accurate calculations (Brand, van der Merwe, et al, 2000;Cloete et al, 2012), but the newly acquired information still pales in comparison to other monogastric species, such as pigs and poultry (Brand & Olivier, 2011), however.…”
