Présence de Palaeoperdix media (Aves, Galliformes, Phasianidae) et d'autres oiseaux dans le Miocène du Portugal

A distal part of tibiotarsus from Charneca do Lumiar (Langhian, MN5) is identified as Palaeoperdix media, formerly known as Miophasianus medius. This species is thus known on a large area of the Palearctic province, from Portugal to Poland, and from the beginning of the Middle Miocene (MN 5) to the beginning of the Upper Miocene (MN9). An indeterminate, Gruid from Quinta das Pedreiras (Lower Langhian, MN4) and a few marine birds' remnants from Penedo Norte (Burdigalian) have been recognized.

Capillariid nematodes in Brazilian turkeys, Meleagris gallopavo (Galliformes, Phasianidae): pathology induced by Baruscapillaria obsignata and Eucoleus annulatus (Trichinelloidea, Capillariidae)

The pathology induced in turkeys (Meleagris gallopavo) by two capillariid nematodes, Baruscapillaria obsignata and Eucoleus annulatus is described together with data on prevalences, mean infection and range of worm burdens. B. obsignata occurred with a prevalence of 72.5% in the 40 examined hosts in a range of 2-461 nematodes and a mean intensity of 68.6, whereas E. annulatus was present in 2.5% of the animals, with a total amount of five recovered parasites. Gross lesions were not observed in the parasitized birds. Lesions due to B. obsignata mainly consisted of the thickening of intestinal villi with a mild mixed inflammatory infiltrate with the presence of mononuclear cells and heterophils. The lesions induced by E. annulatus were represented by foci of inflammatory infiltrate with heterophils in the crop epithelium and esophagus of a single infected female. These are the first pathological findings related to the presence of capillariid worms in turkeys to be reported in Brazil so far. Capillaria anatis, although present, was not pathogenic to the investigated turkeys.

Eimeria pavoaegyptica sp. nov. (Apicomplexa: Eimeriidae) in faeces of Indian peacocks, Pavo cristatus Linnaeus, 1758 (Galliformes: Phasianidae) from Egypt

Coprological examination of 15 Indian peacocks, Pavo cristatus, revealed the presence of a coccidium species of the genus Eimeria, which apparently represents a previously undescribed species. Sporulation is exogenous and fully developed oocysts of Eimeria pavoaegyptica sp. nov. are ellipsoidal, with a dimension of 15 (13-16) × 12 (10-12.9) μm and with a shape index of 1.25 (1-1.3). The sporulated oocysts have no micropyle but enclose one large rectangular-shaped polar granule and an oocyst residuum. The oocysts have a distinct two-layered wall, which is ~1.7 μm thick. The outer layer has a smooth texture; it fills ~¾ of the total thickness and appears bicolored. The sporocysts are boat-shaped, of about 10 (9-11) × 4 (4-4.7) μm; their average shape-index is 2.5 μm with a small pointed Stieda body and a smooth, thin single-layered wall. No substieda body is detected. The sporocysts contain numerous, nearly uniform granular residua. The sporozoites are banana-shaped, 6 × 3 μm and each has two different-sized refractile bodies.

As relações parasito hospedeiros em Strigiformes são novas no Brasil.

Níveis de proteínas nas dietas de faisões em crescimento

The experiment with pheasants in initial growth phase (1 to 35 days of age), which had as its objective evaluating the nutritional needs of pheasants in the growth phase as to protein levels in the diets, was conducted on a pheasant farm located at Ribeirão Preto, SP, Brazil. Small pheasants were used, which were submitted to isocaloric diets containing 26%, 28% and 30% of crude protein. The experimental design was totally random with four repetitions of 30 birds per parcel, totaling 360 birds. The results showed that a 30% crude protein level should be recommended for pheasants in the growth phase (1 to 35 days of age).

Estudo morfológico e histomorfométrico sobre variações sazonais do ducto deferente de codorna da variedade italiana

In the autumn the vas deferens of the Italian variety of domestic quail appeared as a single, thin, and straight duct along its total extension. Thus, transversal histologic sections of this duct showed a circular tubular shape. The pseudoestratified columnar epithelium that lined the vas deferens presented longitudinal folds which invaded the lumen frequently empty of spermatozoa. Although in the winter, spring and summer the usual morphological appearance of the quail's vas deferens was seen as a highly coiling duct. So, each transversal histologic section of the vas deferens, in all the segments, showed parallel cut sections of the duct being irregular in shape and variable in number and interconnected by the adventitial loose connective tissue. In these observations, the tubular lumen was totally performed by spermatozoa and seminal fluid. Consequently, with previous base on the testis kinetics of the Italian quail variety, it was concluded that the spermatozoa production, followed by emission, storage and ejaculation of spermatozoa through the vas deferens did not stop during the winter, spring and summer, but ceased in the autumn the quiescent phase of the circannual reproductive cycle in this bird.

Efeito dos níveis de triptofano digestível em dietas para codornas japonesas em postura

The adequate level (0.12, 0.16, 0.20, 0.24, and 0.28%) of the dietary digestible tryptophan was evaluated in 400 laying Japanese quail from 21 to 30 weeks old. The animals were housed in laying cages, with initial weight of 158.50 g and egg production average of 84.50%. A completely randomized blocks design, with eight blocks, five diets, eight replicates of ten birds per replicate and three experimental periods of 21 days each was used. Feed intake (g/bird/day), digestible tryptophan intake (mg/bird/day), egg production (%/bird/day), egg weight (g), egg mass (kg/bird/day) and feed conversion (kg feed intake per kg eggs and dozen eggs) were the characteristics evaluated. Only the characteristics digestible tryptophan intake and egg production rate show significant effects of digestible tryptophan levels in the diets. Performance response of the Japanese quails in posture, regarding the adjustment obtained through models of linear regression and broken-line regression model, and the biological interpretation, allow to conclude that to obtain the best productive performance, the Japanese quails diets should contain the level of 0.21% digestible tryptophan, that results in a daily intake of 45.0 mg/ bird of digestible tryptophan, corresponding to the digestible tryptophan: digestible lysine ratio of 21%. © 2008 Sociedade Brasileira de Zootecnia.
