Nowadays traditional pork is still remaining the most popular meat in many European countries. In contrast, presently there is a growing interest in the production and marketing of non traditional snail meat. The aim of the present study was to compare the quality characteristics of pork and snails’ meat, to determine an impact of animal species on meat quality and to analyse the correlation coefficients of some parameters of meat quality. The meat quality characteristics, as chemical composition and some physical properties, were evaluated after deep-freezing. It was determined that snail meat contained by 11.50% higher amount of water, by 14.60% higher amount of mineral substances and by 77.04% higher amount of amino acid hydroxyproline, but by 77.38% less fat, by 37.94% less protein and by 43.28% tryptophan if to compare to the pork meat. Besides, pH in snail meat tended to be alkaline while in pork meat – acid. Moreover, snail meat was darker, pale red and its yellowness was more intensive than that of the pork meat. The correlation between fat and protein in pork and snail meat, pH with tryptophan and hydroxyproline was negative, whereas pH with fat, and dry matter with ash – positive. However, in pork meat tryptophan and hydroxyproline correlated negatively, while in snail meat – positively. Meat chemical composition and physical properties were effected by animal species.

Serological study of porcine reproductive and respiratory syndrome virus (PRRSV) infection in pigs and wild boars was conducted in Lithuania between 2009 and 2013. Antibody level was measured using a commercial ELISA. The 4.32% (95% CI 3.92-4.72) out of 9856 examined porcine sera were positive for the PRRSV antibodies. The antibodies were detected in 11.82% (95% CI 10.28-13.36) of all investigated serum samples of sows and gilts. As much as 8.2% of serologically positive samples (95% CI 6.83-9.57) were determined in the piglets under three months of age. Considerably smaller (P < 0.05) seroprevalence was detected in boars (0.62%) and fattening pigs (1.84%). From 1357 examined sera of wild boar, collected between 2009 and 2013 hunting seasons, 5.38% (95% CI 4.52-8.2) of samples were positive for PRRSV antibodies in 23 locations out of 50 investigated. The analysis of seroprevalence in different age groups of wild boars showed that PRRSV antibodies were detected in all age groups; however, it was significantly higher in adults than in juveniles or subadults and reached up to 10.02% (95% CI 7.39-12.65).

The purpose of this study was to broaden the basic knowledge of corneal morphological structures in pigs, cows and rabbits and to find morphological and histological differences in the constituent corneal structures. After slaughter, corneal samples of 24 animals, including cows, pigs and rabbits, were investigated. Forty-eight eyeballs (n = 48) of 8 pigs, 8 cows and 8 rabbits were used for this study. Central corneal thickness (CCT) values in cows were higher than those in pigs (P < 0.001) and rabbits. In rabbits, CCT, as a percentage of the eye axis length, was 55.03% greater than in cows and 40.55% greater than in pigs (P < 0.001). The thickness of substantia propria (stroma) depended on the species and accounted for more than 80% of the thickness of all layers of the cornea. The thickness of the anterior epithelium amounted to 15.81% of the thickness of all layers of the cornea in cows, 11.79% in pigs, and 8.48% in rabbits (P < 0.001). The data analysis showed that the caudal limiting membrane + endothelium was the thinnest layer of the cornea, with thickness ranging from 0.88% to 2.40% of the total thickness of all layers of the cornea in the three species under study (P < 0.001). A statistically significant negative correlation was determined between the anterior epithelium and substantia propria in corneas of cows, pigs and rabbits (P < 0.001). This paper describes the morphometric parameters of the cornea in pigs, cows and rabbits. These parameters will be of use to scientists using animal models in vision science research.

The aim of this study was to investigate the influence of long-term building construction noise from refurbishment, which including vibration, on some physiological parameters and histopathological changes of organs of Wistar rats. Twenty 12 month old female rats were divided into two groups: rats group I (n = 10) were exposed to long-term construction noise and rats group II (n = 10) were kept under normal noise level. Study results revealed that long-term construction noise from building refurbishment has an influence on body weight, haematological and some serum biochemical parameters affects caecal microbiota, and causes histopathological changes in the organs of adult female Wistar rats. It was noticed that rats in group I exihibited significantly higher mean values for total protein, albumin and lower values for glucose, AST, ALT, blood urea nitrogen, haematological and caecal microbiota parameters than rats in group II. The most common pathologies were determined in the kidney, liver and lungs. Other observed pathologies were lymphadenopathy, catarrhal inflammation of the intestines, spleen hyperplasia and mammary gland adenofibroma. Single cases were subcutaneous fibroma in the thoracic region, abortus with uterine inflammation and thymus hyperplasia with formation of cysts were found.
