Zarażenia pierwotniakiem Neospora caninum są w stadach bydła jedną z przyczyn strat w sektorze rozrodu (ronienia, resorpcje i powtarzanie rui, rodzenie cieląt z objawami klinicznymi neosporozy lub zdrowych klinicznie, ale trwale zarażonych). Obecność w stadach nawet jednego osobnika, będącego źródłem inwazji i rezerwuarem pierwotniaka (ang. „single reactor") determinuje utrzymywanie się inwazji...
Zachowanie się białek surowicy oceniano u psów (n = 21) z erlichiozą (Ehrlichia canis) potwierdzoną serologicznie testem immunofluorescence pośredniej IFAT (miana od 1:20 do 1:1280). W porównaniu z grupą kontrolną 20 zdrowych klinicznie psów (wynik badania testem IFAT ujemny) - w grupie psów zakażonych wykazano statystycznie istotne zmniejszenie koncentracji białka całkowitego (p<0,05), albumin...
W warunkach hodowli wielkostadnej często spotykanym problemem jest niedostateczne przekazywanie odporności siarowej na potomstwo, zatem używanie preparatów zawierających w swoim składzie immunoglobuliny powoduje wzrost stężenia krążących w organizmie przeciwciał ochronnych. Zastosowanie w warunkach doświadczalnych preparatów zawierających w swoim składzie frakcje immunoglobulin powodowało wzrost...
Celem badań było porównanie zawartości określonych składników mineralnych w surowicy oraz osoczu krwi 12 klinicznie zdrowych koni, utrzymywanych w jednakowych warunkach środowiskowych. Na podstawie wykonanych analiz stwierdzono, iż zawartość wszystkich badanych pierwiastków w surowicy mieściła się w granicach norm podawanych w piśmiennictwie. W dwóch próbach zawartość Ca, Mg i Fe w osoczu była niższa...
Celem doświadczenia była ocena zawartości wybranych metali ciężkich (ołowiu, kadmu, miedzi i niklu) w mleku przeżuwaczy (krów i kóz), a także porównanie poziomów tych metali u zwierząt pochodzących z różnych regionów - zanieczyszczonego i uważanego za wolny od zanieczyszczeń przemysłowych. Zawartość metali ciężkich została oznaczona w próbkach mleka surowego krowiego i koziego. Zanotowano następujące...
Analyses were conducted on 20 adult females of the raccoon dog (Nyctereutes procyonoides). The measurements allowed to calculate the mean length of the raccoon dog, amounting to 247.09 cm, and the mean total length of intestines, amounting to 207.83 cm. Mean values of individual intestinal fragments, i.e. duodenum, jejunum, ileum, caecum and colon with rectum amounted to 31.17, 170.00, 6.65, 8.04...
The aim of this study was to evaluate sexual dimorphism of the selected mor- phometric traits in Hucul horses. Examinations have comprised 276 horses (96 stallions, 140 mares, 40 geldings) of both sexes aged between 6 days and 28 years. Each of them has been subjected to 37 body measurements. The acquired values have been put to statistical analysis. Sexual dimorphism of the examined individuals...
The aim of the study was to evaluate chosen Hucul horses' morphometric traits with the use of point method exemplified by chosen Hucul horses' morphometric traits. The study has been conducted in 561 Hucul horses of both sexes, which were divided into 6 age groups. Each specimen underwent the measurement of the height at withers, the thorax's circumference, the metacarpus's circumference, the head's...
The metodology of a determination of some biometals content, i.e. chromium, cobalt, manganese, nickel and iron in Saccharomyces cerevisiae yeasts using UV-VIS spectrophotometer was worked out. An accuracy and precision of chosen analytical methods was determined. The comparison of results obtained with spectrometric ICP-AES method was conducted. Differences of mean values of results between those...
Under the light microscope, the epithelium of filiform papillae consists of an anterior and a posterior side. On the anterior side of filiform papillae the epithelium exhibited characteristics of soft keratinization, while on the posterior side - there were characteristics of hard keratinization. Conical papillae were covered by nonkeratinized epithelium. The keratinized layer was observed only...
The objective of the presented research project was to analyze pork quality factors with regard to various breeders of slaughter animals. Experiments were carried out on swine half carcasses, collected from fatteners delivered to slaughter house by three breeders from Wielkopolska province. Two types of muscles: m. longissimus lumborum and m. semimembranosus and two types of adipose tissue: subcutaneous...
Our paper describes case of lerneosis in rainbow trout (Oncorhynchus mykiss). Lerneosis is disease of fish caused by Lernaea cyprinacea. This species is a cosmopolitan ectoparasite, worldwide distributed. Invasion by L. cyprinacea were rare described in Poland. This parasite is highly adapted to a parasitic life. The life cycle of L. cyprinacea is composed of nine stages. After mating males (mature...
The first signs of formation of the posterior serous lingual glands (von Ebner's glands) were observed at day 22 of prenatal development of the rabbit. The development of glands was initiated by the appearance of epithelial bands, growing into the connective tissue. At day 26 p.c. the epithelial bands were longer. At day 1 of postnatal life the secretory parts of glands were formed together with...
A total of 129 tongues were analyzed, which were collected post mortem from rabbits (Oryctolagus cuniculus f. domestica), aged from day 15 of prenatal development (p.c.) to the 6th month of postnatal life (p.p.). The tongue was formed on the basis of its primordia starting as early as day 15 p.c. At that time the first primordia of lingual papillae were observed, which were primordia of circumvallate...
The study has been conducted on 20 Bufflo female rats aged 4-6 months, from which the uterus strips have been taken directly after slaughter. Isolated uterus strips were placed in 4 automatic water bath chambers. After recording of spontaneous contraction activity of the isolated strip, calcium channel blockers i.e. diltiazem, nifedypine, verapamil were added into the bath organ. Doses of the preparations...
