The female should be intro- diced romaine lettuce, spinach, dandelion and other duced to the enclosure a few hours prior to the male. In several species In some species, it is possible to keep several males (some grouse), chicks obtain food by picking at the together if there are no females present. In monogamous spe- vided intact plants that are placed in the ground or cies, only a single pair should be housed together. Chicks that are to be released into the wild ing the breeding season may attack other males, must be introduced to their natural foods to prevent other bird species or even the keeper. Perhaps chicks are imprinted with food male and mock escape by the female is normal behav- shapes and colors, or at the least, they learn what ior in some species like eared pheasants and fran- foods to consume from the hen. If there is insufficient space for the hen to The chicks of some gallinaceous birds will not pick escape, she may be injured or killed by the cock.

A box placed approximately 150 cm from the premature cessation of brooding if the natural ground and filled with hay and foliage can be used as incubation period of the foster hen is shorter than an artificial nest. Nests of ground- and tree-nesting birds should be inconspicuous to provide trauma or death of the chicks if the hen recognizes the pair with visual security but should be placed them to be strange (this is a particular problem such that the birds can easily look out. In one breeding season, an Australian by placing the eggs in an incubator for the last third Brush Turkey hen lays about 25 to 30 eggs.

Behavior of ceous birds, owing to the uncommon brooding biology free-ranging birds is dramatically different from that of these birds. The brain volume of domes- parents but by solar heat, fermentation heat or geo- ticated turkeys is 35% smaller than that of their thermal energy. The eggs are thin-shelled and depression in the soil and may be padded with leaves, contain a large yolk that is rich in lipids.

Only antibody preparations from guinea pigs cheap lasuna 60caps otc, but not from rabbits purchase 60caps lasuna amex, were suitable for identifying antigens. The use of immuno­ globulins precipitated by ammonium sulphate resulted in a decrease of sensitivity. Variation o f the concentration o f the radiolabelled antibody isolated by affinity chromatography. A-Ab as solid-phase antibody B0 = incubated radiolabelled polysaccharide antibody В = bound radiolabelled antibody. The sera of the patients were sampled 2 to 5 days after the last positive blood cultures. In the sera of two patients, cpm-values equivalent to approximately 1 ng/mL polysaccharides (> 3 times background values) were evaluated. However, in all studies false negative antigen test results were found in the range from 30% [4, 10] to 100% [11 —13] of the cases with systemic candidiasis. Our in-vitro studies showed that specific blocking antibodies impair the detection of antigens. If sera with high levels of polysaccharide antibodies were tested, the detection limit was raised from 1 ng/mL to 2000 ng/mL. Thus, some false negative results in previous assays may be caused by the interference of specific antibodies in vivo, which block binding sites even at antibody concentrations found in normal sera by forming immune complexes. Heating (95°C, 15 min) of sera containing polysaccharide antigens and antibodies destroys the antibodies in the immune complexes. This procedure considerably increased the test sensitivity and restored the detection limit almost completely (Fig. The recovery of various amounts of polysaccharides added to individual sera after heating and the precision of the assay were excellent (Table I). The comparison of affinity-purified Candida antibodies with protein А-isolated antibodies bound to the solid phase showed that one tenth of the former is sufficient to get the same test results as those obtained with protein A-antibodies. The sera of the patients were obtained 2 to 5 days after candidemia; antigens may have cleared from circulation at the time we tested the sera. Further studies on sera of patients with systemic candidemia are necessary to evaluate the diagnostic significance of Candida antigenemia. The necessity of such a method became apparent because of the massive abuse of these drugs in sports, and their consequent banning by official authorities. Since then we have developed alternative methods for both the above-mentioned groups of steroids, using tritiated or, alternatively in the steroid nucleus, radioiodinated ligands, and also for nortestosterone antisera with diverse specificity, to enable the detection selectivity of the latter steroid to be improved [2-4]. Though selective enough, the method did not reveal the main nortestosterone metabolites found in urine, i. Here we wish to report the preparation of four different immunogens for raising antisera, taking into consideration the above metabolites. The 17-carboxymethyloximes and За-hemisuccinates of 19-norandrosterone and 19-noretiocholanolone were synthesized and attached to bovine serum albumin by conventional methods [6]. The initial noretiocholanolone was purchased from Organon (Netherlands), and norandrosterone was prepared from nortestosterone by original three-step synthesis. We thus developed a radioimmunoassay for this compound which was kindly provided by Dr. The possibility of generating a chemically reactive form of these vinca alkaloids, as described by Barnett et al. The resulting desacetyl monohydrazide was then converted into a reactive acid azide by reaction with nitrous acid (10 jumol) at 4°C for 10 min, extracted by methylene chloride and dried. This conjugate was iodinated with 125I sodium iodide by the lactoperoxydase procedure in order to reduce the formation of non- immunoreactive radiolabelled by-products. The immunogen was emulsified in complete Freund adjuvant and injected subcutaneously into two rabbits at three-week intervals. Strong responses were obtained with both animals, leading to hyperimmune antisera which bound 50% of the radiolabelled probe (10 000 counts/min) at a final dilution of 1/2 000 000, based on the polyethylene glycol precipitation of immune complexes. Des lapins ont été immunisés avec ce conjugué et des anticorps capables de lier la suriclone marquée ont été obtenus. L’extraction de la suriclone du plasma ou des urines a été rendue nécessaire en raison d’une interférence importante due au plasma et à la présence de métabolites en quantités importantes et reconnus par les anticorps. La suriclone est extraite du plasma ou des urines par passage sur une cartouche de silice greffée Cl 8 (Waters) éluée avec l’acétonitrile. La séparation chromatographique est effectuée sur une colonne Spherosil X0A 600 (0,6 X 10 cm) (phase mobile: méthanol, eau, triéthylamine, éther isopropylique, isooctane; 12,5/0,65/0,2/50/37,5, V/V).

Two people are required and the semen is released, while simultaneously and for collecting the semen. The other person holds a Pasteur pipette in one hand, and the tail is lifted up and held between the thumb and index finger of the same hand. The opening of the cloaca is literally pressed together to push the sper- matozoa out of the papilla of the ductus deferens.

The bird is restrained inside the palm of one hand, the head and the leg to be injected are fixed between the middle and index fingers, and the other leg is held between the ring and little fingers. The injection is administered at the middle of the femur, and the needle runs distally. The needle must be advanced approximately 5 to 7 mm into the mus- cle, not too flat or too far laterally.

In one case in Europe, this technology was used to prove that a group of a pair of supposedly proven breeding birds had not birds had been illegally imported, resulting in the been the parents of a neonate. Birds for pets and aviculture are C H A P T E R C being increasingly supplied by domestic breeding programs, and the importation of wild- caught birds is no longer necessary or acceptable for most species. As aviculture advances, veterinarians must play a major role in maintaining the health and increasing the productivity of individual pairs and flocks. The quality of avian medicine available for 2 individual birds has advanced tremendously in re- cent years. The successful growth of aviculture will require simultaneous advances in the knowledge and application of preventive medicine from the veteri- nary community. Avicultural medicine differs from clinical care of in- dividual companion birds in several very important ways. The com- mercial producer, as is the case with any livestock Keven Flammer producer, often operates on a slim margin of profit, which can be profoundly affected by disease or man- agement problems. Understanding the economics of the companion bird industry is vital for a successful avicultural practice. Hobbyists typically sell offspring to recover the costs of maintaining their collection or to allow The Veterinarian / Aviculturist Relationship them the freedom of devoting more time to avicul- ture.
