Abstract: En la última década, la crianza del avestruz en Chile ha ido aumentando sustancialmente, por lo cual se ha hecho necesario incrementar los estudios para mejorar la producción de esta especie. La literatura se ala sólo estudios sobre la fisiología y anatomía de esta especie. Nuestro objetivo es aportar al conocimiento de la histología normal de las glándulas anexas al aparato digestivo. Esta investigación se realizó con 6 avestruces clínicamente sanas, de las que se obtuvieron muestras representativas del hígado, pro ventrículo y páncreas. Se realizaron cortes histológicos, los que fueron te idos y montados para su análisis comparativo bajo microscopio de luz, entre avestruz y gallina. La histología de las glándulas anexas del aparato digestivo es semejante a la descrita en la gallina. Sin embargo, en el hígado los cordones de hepatocitos se disponen en forma radial, tanto alrededor de la vena central como de los espacios porta, característica no observada en otras especies. Con respecto al pro ventrículo, en la mucosa se observan glándulas tubulares simples o ramificadas, semejantes a las glándulas fúndicas de los mamíferos. En la submucosa se observan glándulas túbuloalveolares compuestas con células parietales. El páncreas no presenta diferencias destacables In the last decade the upbringing of the ostrich in Chile has increased substantially, for this reason it is necessary to increase the studies to improve the production of this species. The literature only points out studies on the physiology and anatomy of this species. The purpose of this work is to contribute to the knowledge of the normal histology from the annexed glands to the digestive system. This study was carried out clinically using 6 healthy ostriches, of which representative samples of the liver, proventricle and pancreas. Histological sections were realized, mounted and stained for their comparative analysis under low light microscope to describe with those cited in the hen. The histology of the annexed glands from the digestive system is similar to the described in the hen. However, in the liver the arrangement hepatic cords so is in the central vein such as the portal spaces is radial, characteristic not observed in other species. In relation to the histology of the proventricle, the tubular glands are quite, similar to the fundic glands of the mammals. In the submucosa compound tubulosacular glands are observed, with parietal cells. The pancreas doesn't present prominent differences

Abstract: The ostrich (Struthio camelus var. domesticus) is an important animal in the livestock industry in South Africa. Ostrich production is an intensive production system and feed cost contributes approximately 75% of the total cost of production. The objective of this study was to determine the effect of the replacement of soybean oilcake meal (SOCM) with cottonseed oilcake meal (CSOCM) on the production performance of slaughter ostriches. A total of 105 birds of both sexes were divided into five groups of 21 birds each. All birds were fed five iso-nutritional diets in which SOCM was gradually replaced by CSOCM (0% up to 12% of the total diet). Ostriches in each treatment were subdivided into three replicate pens containing seven birds each. Body weights of birds were recorded at the start of the experiment and thereafter on a monthly basis throughout the study. Inclusion level of CSOCM had no effect on the feed intake and feed conversion rate of slaughter ostriches. Birds consuming the diet with 0% CSOCM had a significantly lower growth rate than the birds consuming the diets containing respectively 9% and 12% CSOCM. In a complementary palatability study, no significant differences in feed intake were observed between the diets with and without CSOCM.

Abstract: Criatórios de avestruz têm se tornado comuns no Brasil, mas por se tratar de espécie exótica, as informa es sobre as doen as desses animais no nosso ambiente s o escassas. Um avestruz de cinco meses de idade apresentou tosse, anorexia, perda de peso, dispnéia discreta, temperatura corporal normal e morreu oito dias após o início dos sinais clínicos. Macroscopicamente foram observados nódulos múltiplos no pulm o e nos sacos aéreos. Histolopatogicamente, observou-se pneumonia granulomatosa e necrosante multifocal com hifas ramificadas e septadas intralesionais com características morfológicas de Aspergillus sp. Nos sacos aéreos, além das hifas e processo inflamatório adjacente haviam vários micélios com conidióforos na superfície interna. Foi isolado Aspergillus fumigatus dos tecidos afetados. De acordo com os achados histopatológicos e micológicos firmou-se o diagnóstico de pneumonia e aerossaculite micótica severa causada por Aspergillus fumigatus. Com base nas informa es disponíveis na literatura, esse é o primeiro caso de aspergilose em avestruz documentado no Brasil.

Abstract: El corazón del avestruz (Struthio camelus), al igual que el corazón de las aves domésticas, tiene una valva atrioventricular derecha muscular sin cuerdas tendinosas, y una valva atrioventricular izquierda membranosa con cuerdas tendinosas que se extienden entre las cúspides y 3 músculos papilares. El objetivo del estudio fue describir los músculos papilares, número, ubicación y algunas características morfológicas. Se utilizaron 50 corazones de avestruz (Struthio camelus), que fueron disecados y fijados en formalina tamponada al 10%, y se obtuvieron cortes histológicos de 7 mieras los cuales fueron te idos con Van Gieson y H-E. El estudio macroscópico mostró ausencia de músculos papilares en el ventrículo derecho y en el ventrículo izquierdo 3 masas musculares formadas por trabéculas carnosas longitudinales que dan inserción a las cuerdas tendinosas. En los cortes histológicos se observó que los puntos de inserción dorsal y ventral de la valva atrioventricular derecha a la pared ventricular, son prolongaciones del músculo que forma la valva y presentan fibras conductoras cardíacas. En el ventrículo izquierdo, las trabéculas carnosas longitudinales también presentan fibras conductoras cardíacas las que se extienden hasta la zona de inserción de las cuerdas tendinosas. Los resultados muestran que el corazón del avestruz (Struthio camelus) no tiene músculos papilares de forma cónica como en el corazón humano, son formaciones musculares más desarrolladas que en el corazón de las aves domésticas y funcionalmente actúan como músculos papilares al presentar fibras conductoras cardíacas. The heart of the ostrich (Struthio camelus), just like the domestic birds's heart, has a muscular right atrioventricular valve without chordae tendinae and a membranous left atrioventricular valve with chordae tendinae than extends between the cusps and 3 papillary muscles.The aim of the study was to describe the papillary muscles, number, position and some morphologic characteristics. Fifty ostrich hearts (Struthio camelus), were dissected and fixed in 10 % formalin and which got histological slices from 7 microns themselves they were stained with Van Gieson and H E. The macroscopic study evidenced absence of papillary muscles in the right ventricle and in the left ventricle 3 muscular masses formed by longitudinal trabeculae carneae that give insertion to the chordae tendinae. It was observed in the histological slices that the dorsal and ventral insertion points of the right atrioventricular valve to the ventricular wall, are prolongations of the muscle that forms the valve

Abstract: La disposición de las fibras del miocardio ventricular del corazón del avestruz (Struthio camelus) fue estudiada macro y mesoscópicamente en 14 corazones de avestruz, disecados mediante una adaptación del método de Pettigrew. Se identificaron tres capas musculares: superficial, media y profunda, de acuerdo a la orientación de las fibras del miocardio ventricular. Las fibras de la capa superficial son comunes a ambos ventrículos, en cambio las fibras de las capas media y profunda son propias de cada ventrículo. El ventrículo izquierdo presenta una gruesa capa muscular media, que también constituye mayoritariamente el septo interventricular y el ápex del corazón. The arrangement of the ventricular myocardial fibers of the ostrich heart (Struthio camelus) was macro and mesoscopically studied in 14 ostrich hearts, dissected by an adaptation of the Pettigrew method. Three different myocardial layers - superficial (subepicardial), middle and deep (subendocardial) - have been identified according to the ventricular myocardial fibers orientation. The superficial fibers are common for both ventricles, however, the fibers of the middle and deep layers, are unique to each ventricle. The left ventricle presents a thick middle muscular layer, which also constitutes the main part of the interventricular septum and the heart apex.

Abstract: Measurement of haematologic and biochemical parameters is an important part of evaluating the health of ostrich chicks. Thus aimed to determine haematological and biochemical parameters in the blood of one-day old ostriches in intensive breeding. The blood count, iron and copper concentrations were determined in 30 clinically healthy, one-day old unsexed ostriches of the domesticated subspecies of ostrich Struthio camelus domesticus. Their importance in clinical evaluation and disease condition is discussed. In this study the following mean values were determined in 30 clinically healthy, one-day old unsexed ostriches: erythrocyte count = 1.48 x 1012/L, MCV = 126.6 fl, MCH = 52.9 pg, MCHC = 418 g/L, haemoglobin concentration = 79 g/L, haematocrit = 18.87%, platelet count = 8.6 x 109/L, leucocyte counts 9.1 x 109/L, heterophils = 82%, eosinophils = 0.5%, basophils = 2.5%, lymphocytes = 11%, monocytes = 3.4%, iron = 4 mmol/L and copper = 2.6 _mol/L. We hope that the data presented in this study will be an incentive to clinicians and scientists in the field, to use haematological and biochemical examinations as an aid to the diagnosis of diseases in ostriches.

Abstract: In order to better define the effect of the sex on the metabolic profile of young ostriches (Struthio camelus domesticus), forty birds were divided into two groups by sex (20 males vs20 females). The animals were fed ad libitumnatural pasture and corn silage. The daily ration was completed by administering 1200 g/head of a commercial concentrate with the following chemical composition expressed as a percentage of dry mat- ter: crude protein 18.8, crude fibre 8.4, ether extract 3.6, ash 7.5. After about 12 h of fasting, in the mor- ning the blood was collected from the wing vein. The following biochemical parameters were determined: glu- cose, cholesterol, triglycerides, lactate (LAC), total protein (TP), uric acid, total bilirubin (Tbil), creatinine (CREA), calcium (Ca), magnesium (Mg), phosphorus (P), natrium (Na), potassium (K), chloride (Cl), iron (Fe), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), choline- sterase (ChE); α-amylase (Amyl), lipase (LIPA); γ-glutamyltransferase (GGT). Sex significantly affected only some haematic parameters: in the females total protein and calcium were higher than in the males (TP, 43.3 vs38.9 g/l, respectively for females and males, P< 0.05; Ca, 2.99 vs2.59 mmol/l, respectively for females and males, P< 0.01). The other haematic parameters did not show signifi- cant differences by sex, and the average values were: glucose (9.87 mmol/l), cholesterol (1.96 mmol/l), triglycerides (1.56 mmol/l), LAC (6.60 mmol/l), uric acid (361 mmol/l), CREA (31.95 μmol/l), Na (144.8 mmol/l), K (3.27 mmol/l), Cl (109.7 mmol/l), P (1.47 mmol/l), Mg (1.10 mmol/l), Fe (9.22 μmol/l), Tbil (9.28 μmol/l), AST (341.3 U/l), ALT (11.42 U/l), AP (75.8 U/l), GGT (10.07 U/l), Amyl (6.97 U/l), LIPA (241.2 U/l), ChE (385.1 U/l). The results of our study, in agreement with previous findings, contribute to enhance the knowledge on the metabolic profile of ostriches in function of the sex.
