Бактериологическим исследованиям подвергли 7243 птиц, павших на территории Ольштынского воеводства в 1985—1987 гг. Эти птицы происходили из обобщественных и частных ферм. Изолировали 1431 штамм из рода Salmonella (1041 от индеек, 327 от кур, 36 от уток, 27 от гусей). Нежгутикованные штаммы составляли 1,8%, жгутикованаые — 98,2%. В очередаые годы анализируемого периода отметилось незначительное понижение инфекций этим микроорганизмом, так как в 1985 г. отметили его у 22,0%, в 1986 г. у 19,54%, а в 1987 г. — у 18,2% птиц, исследуемых бактериологически. Изолированные штаммы Salmonella принадлежали к 17 серотипам. Чаще всего появлялись серотипы: S. typhimurium (36,15%), S. saint-paul (20,52%), S. enteritidis (18,62%), S. derby (6,22%).

Bacteriologically were examined 7243 birds in the Olsztyn voivodeship in 1985-87. The birds were reared in private and collective farms. 1431 strains of Salmonella were isolated (1041 strains from turkeys, 327 from hens, 36 from ducks and 27 from geese). Flagellar strains constituted 98.2% of isolates. In successive years of the examined period of time the percent of Salmonella infections in birds decreased. In 1985 Salmonellae were detected in 22.0%, in 1986 in 19.54% and in 1987 in 18.2% of bacteriologically examined birds. The isolates belonged to 17 serotypes. The most prevelent were the following serotypes: S. typhimurium (36.15%) S. saint-paul (20.52%). S. enteridis (18.67%) and S. derby (6.22%).

The examinations were done in two (A and B) typical slaughter turkey rearing pens for 20 weeks (pen A) and for 15 weeks (pen B). Among the examined parameters of microclimate temperature, humidity, cooling, lighting and concentration of ammonia showed the highest deviations from normal values. Losses and cullings (16.02% in pen A and 9.9% in pen B) resulted mainly from diseases caused by a conditionally pathogenic microorganisms. Unproper environmental conditions, mixed feeds of low quality and unproper selection of chicks in hatcheries predisposed to diseases caused by conditionally pathogenic bacteria. In pen A a body weight of females after 16 weeks was 5.5 kg, males after 20 weeks was 10.1 kg and feed consumption was 3.45 kg/kg of increased body weight. In pen В a body weight of males after 15 weeks reached 5.8 kg whereas feed consumption was 3.04 kg/kg of body weight increase.

Avian adenoviruses (Aviadenovirus) belong to three groups. Group I contains five aviadenovirus species (A-E) with twelve serotypes isolated from fowls as well as duck adenovirus, pigeon adenovirus and turkey adenovirus. Group I of aviadenovirus plays no major role in mixed infections, although FadV-4 strains cause a dangerous disease in chickens - hydropericardium-hepatitis syndrome. Group II of the aviadenovirus includes the hemorrhagic enteritis virus of turkeys, marble spleen disease virus of pheasants and the splenomegaly adenovirus of chickens. In fact, the adenoviruses of this group are included in the Siadenovirus genus because the techniques of molecular hybridizations and DNA sequencing have indicated that there is a gene coding for sialidaze in their genome. The egg drop syndrome virus however, belongs to group III. Atadenovirus has been proposed as a name for this group of aviadenoviruses as it reflects the high adenine-thymidine (AT) content in their genome. The significance of adenovirus in pathology within poultry is constantly increasing.

Целью работы было определение влияния уровня поссивно приобретенных антител у индюшат на развитие инфекции вирулентным штаммом вируса болезни Ньюкасл. Для исследований использовали индюшат 3 генетических линий белой широкогрудой породы в количестве 210 голов. В работе показали, чта время сохранения в сыворотке индюшат материнских противотел HI против вируса болезни Ньюкасл зависит от их уровня непосредственнo после вылупливания. Эти противотела не защищают птенцов от инфекции большой дозой велогеническогю штамма Радом этого вируса. В связи с этим в случаях большой хнзоотической опасности со стороны азиатской чумы птиц индеек следует вакцинировать уже в 1 день их жизни.

The aim of the studies was to determine the effect of the level of a passive acquired antibodies on the course of infection caused by Newcastle disease virus (NDV) in turkey chicks. The studies were performed on 210 birds from three genetical lines of a White Largechest breed. It was found that a time of persistence of maternal HI antibodies against NDV in turkey chicks depends on their level in blood just after hatching. These antibiodies do not protect chicks against infection with a solid dose of velogenic strain Radom of NDV. Hence, in cases of great epizootic threat by Newcastle disease 1 day old turkey chicks should be vaccinated.

Badania przeprowadzono na 200 kaczkach mieszańcach (kaczor piżmowy x kaczka Pekin z rodu A-44), które podzielono na dwie grupy po 50 samic i 50 samców każda. Doświadczenie obejmowało 12-tygodniowy okres odchowu. Ptaki były żywione do woli. Kaczki z grupy doświadczalnej od 4. do 12. tygodnia życia otrzymywały paszę o zmniejszającej się zawartości białka, a od 7. do 12. tyg. - o zwiększającej się zawartości energii metabolicznej, co uzyskiwano przez stosowanie w mieszance 20-procentowego udziału śruty owsianej (7-11 tydz.), 10- i 25-procentowego udziału kukurydzy, odpowiednio w 10. 11. tyg., a w 12. tyg. - żywienia samą kukurydzą. Stosowana dieta nie wywarła wpływu na badane wskaźniki hematologiczne (Ht, Hb, RBC, WBC), nie zmieniła aktywności enzymów (AST, ALT, AP), w surowicy nato­miast spowodowała wzrost zawartości w surowicy cholesterolu całkowitego i lipidów całkowitych oraz obniżenie zawartości białka całkowitego, glukozy i wapnia.

The experiments described in this paper were carried out on 200 hybrid ducks (musk drake x Pekin duck from the A-44 lineage), which were divided into two groups with 50 female and 50 male individuals each. The experiment involved a 12-month period of rearing. The birds were fed et libitum. The ducks from the experimental groups from the 4th to 12th week of life were fed with feed with decreasing protein concentrations, and from the 7th to 12th week of life were given feed of increasing metabolic energy. This feeding schedule was achie­ved by feeding ducks with a mix of 20% of barley (7-11 week), 10% and 25% of maize in the 10th and the 11th week and in the 12th week they were fed only with maize. The applied diet neither influenced the analysed hematological indices (Ht, Hb, RBC, WBC) nor changed the enzymatic activity in serum (AST, ALT, AP). The diet application resulted, however, in an increase in total cholesterol and total lipids. The concentration of total protein, glucose and calcium decreased.

В работе показали, что ввод Tiamowet индейкам-несушкам, кармленным смесью с натриевым монензином в количестве 60—80 ppm, ведет к появлению сильного отравления, протекающего с расстройствами кровообращения, резким понижением яйценоскости, большим падежом и повреждениями внутренних органов. Доказательством этого был рост активнести в сыворотке аминожрансфераз AspAT и А1АТ, а также понижение уровня полного белка.

It was found that the application of Tiamowet in laying turkey hens fed mixed feed with sodium monensine at a dose of 60—80 ppm caused an acute intoxication with a spontaneous cardiac insufficiency, abrupt decrease of egg production, high percent of losses and destruction of internal organs reflected by an increase of serum AspAT and A1AT and a decrease of a total protein.

Enteroccoci are Gram-positive, granular shaped bacteria classified as a separated genus called Enterococcus spp., which includes 20 species of microbes. They may exist as commensal organisms of the alimentary tract in chickens, turkeys, ducks, geese and pigeons. They have probiotic properties and are able to limit the colonization of the digestive tract by pathogenic bacteria. Enteroccoci strains have a variety of virulence factors: adhesion production, cytolysin, gelatinase, haluronidase, extracellular peroxides and extracellular surface proteins which may cause pathological lesions in poultry. E. faecalis, E. faecium, E. durans, E. hirae, E. cecorum species are pathogenic for poultry. Naturally occurring infections have been reported in chickens and ducks. Young birds are more susceptible. Enterococcal occurrence in chickens may induce low grade infections, septicemia and endocarditis, arthritis of thoracic vertebra and femoral necrosis in broilers (E. faecalis, E. durans, E. hirae, E. cecorum) septicemia and arthritis in ducks (E. faecalis, E. faecium).Sources of infection for poultry may be farm buildings, fowl-runs, or contaminated food. Alimentary and respiratory tracts or intramuscular injections are also infection routes and vertical means of infection are also possible. Pathological lesions in poultry caused by Enteroccoci cause losses due to an increased mortality rate, decrease in growth and difficulties in therapy as a result of the resistance of antibiotics to the microbes. Enterococcal infections in poultry are dangerous for humans because of the transmission of antibiotic resistance to some bacteria strains.

Four groups of turkeys were fed mixtures containing fat of different peroxide values, 5, 50, 100 and 150 mEq O2/kg, respectively, for four months; the fat content over successive months was 2, 3, 4 and 5%. Every month blood samples were collected from 12 birds randomly selected from each group. Moreover, six turkeys from each group were slaughtered to collect samples of the liver, breast muscles and intestines (duodenum). The study revealed, that oxidised fat added to feed mixture reduced considerably the uric acid serum level and vitamin E content in the the liver. There was no indication, that peroxide values of fat in diet had any influence on the serum content of glucose, triglycerides, cholesterol, calcium and phosphorus or on the activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), alkaline phosphatase (AP), lactate dehydrogenase (LDH) and creatine kinase (CK). Oxidised fat in diet, cansed a decrease of ALT and LDH activity in the turkey liver and an increase of LDH and CK activity in breast muscles. The results obtained in this study suggest that the diets applied did not cause significant disorders in the organism homeostasis, which might indicate that the adaptation mechanism of turkeys is activated after the diets had been followed for a long time.
