The purpose of the work was determination of extensiveness and intensity of invasion of intestinal parasites in racing pigeons from the south of Poland including the size of flocks. The material for study included 70 collective samples of faeces. During the research the presence of Eimeria sp. in 65.7% of cases, Ascaridia sp. in 10% of the samples and Capilaria sp. in 17.14% of the samples was stated. The results confirm domination of low intensity of the invasion of Eimeria (below 1 thousand oocytes in 1 gram of faeces in 41.4% of the samples, 1–5 thousand oocytes in 1 gram of faeces in 17.2% of the samples, over 5 thousand oocytes in 1 gram of faeces in 7.2% of the samples). Intensity of invasion of nematoda was low and did not exceed 500 eggs in 1 gram of faeces.

The paper presents and influence of various fats and feed additives on production results in Lohmann Brown laying hens (cage production system) and physico-chemical parameters of the eggs. An introduction of supplementary mixture based on rapeseed oil, glycerol, dried lucerne and humic preparation to hens diet results in some improvement in physical egg shell properties such as thickness and strength. An introduction of an addition of linseed oil, fish oil, dried lucerne and humic preparations in turn, profitably affects fatty acids profile (increased ALA and DHA) as well as A and E vitamins content in yolk, however to a limited degree since it may deteriorate taste and flavor of the eggs.

Feline chronic gingivostomatitis (FCG) is currently one of the most serious problems in feline internal medicine [Southerden and Gorrel 2007]. It manifests with a strong inflammation of mucosal membrane of oral cavity with or without the presence of dental plaque and calculus, what causes difficulties in food administration, weight loss and apathy [Lommer 2003]. The cause of the illness occurrence is not clearly defined. The possibility of bacterial, viral as well as environmental (nutrition and maintenance) factors’ participation in the disease etiology is considered [Lyon 2005, Norris and Love 1999]. As the etiology of the disease and the predisposing factors are not explicitly defined, it is necessary to develop the treatment scheme, which will allow minimizing the consequences of the disease and retraction of the clinical signs. Among the pharmacological treatment methods proposed to inhibit the pathological process use of different forms of chlorhexidine, antibiotics, immunomodulators, corticosteroids, progestagenes and gold salts [Gorrel 2007, Zetner et al. 2007] and feline interferon omega [Southerden and Gorrel 2007, Zetner et al. 2007] are mentioned. The premolar and molar teeth extraction is one of the treatment methods [Hennet 1997]. It is an extreme solution, which should be taken up only when other treatment methods do not give satisfying results. This article describes a pharmacological treatment method in cats with diagnosed chronic gingivostomatitis, consisting in combination of local and general treatment. 22 cats divided into two groups underwent the treatment. After the oral sanitation animals from group I gradually received local and general drugs and animals from group II underwent a combined therapy. The evaluation on each stage of treatment shown higher efficacy of combined treatment.
