The aim of the research was to determine the relationship between the acidity and temperature of the contents of the reticulorumen and abomasum in the first 10 days after calving and to evaluate these factors as predictive traits for the diagnosis of subclinical acidosis. The acidity and temperature of the contents of the reticulorumen and abomasum were measured using specific smaXtec boluses manufactured for animal care. According to the directions of the manufacturer, the boluses were inserted into the reticulorumen of the cows researched with the help of a specific tool. The boluses were inserted into the abomasa by way of surgery, laparotomy and abomasotomy through the right flank. The readings of 7 cows were taken on a total of 10 days, twice a day (at 9 a.m. and at 9 p.m.). In total, 140 measurements were taken. The acidity of the reticulorumen is associated with the acidity of the abomasum. The acidity of the rumen increases, if the acidity of the reticulorumen increases also. A negative correlation was observed between the pH of the contents of the abomasum and this temperature. The increase in the acidity (decrease of pH) of the contents of the reticulorumen increases its temperature and also increases the temperature of the contents of the abomasum. There is a positive statistically significant dependence between the reticulorumen content temperature and the rectal temperature. Through measurement of the ruminoreticular temperature, it is possible to predict the health status of a cow’s stomach in regard to acidosis.

The monitoring of rumen content temperature can be useful for the evaluation of cow health condition and heat. The aim of this research was to evaluate the influence of the circadian rhythm (time of day) and season on reticulorumen acidity (pH) and temperatures (RT) in lactating dairy cows. The research was performed on ten 2nd – lactation, clinically healthy Lithuanian Black and White fresh dairy cows (up to 1 day after calving). The cows were milked twice daily at 05:00 and 17:00. The cows were kept in a loose housing system, and were fed a feed ration throughout the year at the same time, balanced according to their physiological needs. Cow feeding took place every day at 06:00 and 18:00. The pH and temperature of the contents of cow reticulorumens were measured using specific smaXtec boluses manufactured for animal care. The temperature starts rising 6 hours after the evening feeding and milking, whereas 1 hour after the morning milking, it starts decreasing. The lowest temperature observed in the springtime was 38.81±0.001, and the highest was in autumn 39.17±0.001. The pH starts decreasing 3 hours after the morning feed, whereas 4 hours after the evening feed, it starts increasing. The lowest pH was observed in the summertime – 5.99±0.001, and the highest was in autumn and springtime – 6.18±0.001. In conclusion the reticulorumen temperature in lactating cows was found to be influenced by the circadian rhythm and season. The acidity of the reticulorumen content changes similar to the temperature. The pH of the reticulorumen contents was also found to be influenced by the circadian rhythm and season.

The investigation was conducted during 2005-2006 on 4010 dairy cows. Having performed statistical data analysis, we determined that the lowest somatic cell count (SCC) in Red and Red-White cow population was obtained when the milking time was 5-6 min., milking speed was higher than 1.5 kg/min., high milk flow was from 2.51 to 4 kg/min., and in Black-White cow population having a milking time was higher than 7 min., milking speed was from 1.01 to 2 kg/min., a high milk flow – from 2.01 to 4 kg/min. (p<0.001). In Red and Red-White cow population with subclinical mastitis, milking time was longer and milking speed was slower than in healthy cows. High milk flow values were least in healthy Black-White cow population. This determines a more equal milk flow which is desired in milking cows mechanically. Most sensitive to udder infection are 1st lactation cows which have a higher milk flow. A larger phenotype correlation coefficient in Red and Red-White cow population was between the SCC and milking time (-0.089, p<0.01) and between high milk flow (0.086, p<0.01) and milk yield (-0.071, p<0.05). However in Black-White cow population, correlation was found between SCC and milk yield (-0.117, p<0.01) and milking speed (-0.110, p<0.01). Contagious mastitis pathogens were identified in Red and Red-White cow milk samples primarily from productive cows having a milking speed of 1.01-1.5 kg/min., and in Black-White cow population having a milking speed of 1.51-2.0 kg/min.

The aim of the study is to evaluate the possibility of maintenance of cow pregnancy applying GnRH treatment after AI. The experiment was carried out on Lithuanian black-white lactating dairy cows on 90-100 DM. Were selected 45 cows on their 2nd and 3rd lactation with milk yield of 8.500-9.000 kg. The cows with 16 mm or greater (n = 26) CL in ovaries were selected for the experiment. All cows were given the injections of dinoprost solution 25 µg. AI was performed on the cows (n = 20) that showed oestrus. The first group (experimental) of cows (n = 10) were repeatedly given the injections of gonadorelin 100 µg im on the 7th day after AI. The second group (control) of cows (n = 10) were given the injections of 0.9% saline solution on the 7th day after AI. The ultrasound measurement was performed to determine the size of ovaries, and CL’s. Concentration of P4 were detected in milk samples. Ultrasound testing as well as milk P4 determination were carried out 4 times in total, every 7 days starting on the day of AI. After 7 days following the injection of GnRH, and positive increase of the number of cows with accessory CL by 56% was determined, comparing with the second (control) group. The tendency of increasing size of CL in both groups after AI was noticed. The changes in the ovary size were similar in both groups. The average number of CL in the first group was by 36% (P < 0.05) higher than in the second group (1.5 and 1.1). The change of P4 was similar in both groups. The number of pregnant cows in the first group was by 10% higher than in the second group.

The aim of this study was to investigate the effect of electromagnetic fields on BALB/c strain mice on their health, body weight, behavior characteristics, hematological parameters and histopathological findings in the brain. The mice of the experimental groups were exposed to electromagnetic waves by using Nokia 230 and Samsung 19300 Galaxy S III mobile phones situated at 2 cm from the cages. In the present study, it can be concluded that the exposure of mice to mobile phone radiation had an effect on the structure of the brain, behavior and body weight. The waves of mobile phones increased activity characteristics and changed some behavioral categories of mice and also decreased their body weight. Histopathological examination revealed mild edema of neutrophils and degeneration of some neurons and glial cells in the brains of experimental mice. The results of the present study showed that a using mobile phone had an influence on in vivo systems.

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 objectives of this study were to define the effect of the milk progesterone (P4) concentration on estrus expression in dairy cows with high milk yield and to identify the effect of milk yield and parity on the milk P4 concentration and cow’s pregnancy after artificial insemination (AI). In this study, 48 clinically healthy cows without reproduction disorders, on day 90-100 after calving were used. At the beginning of estrus and 12 hours after the beginning of estrus, the milk P4 concentration in dairy cows with high milk yield (group 3) was higher than in group 2 (33.66; 22.36%) and in group 1 (51.60; 65.26%) (P < 0.001). The milk P4 concentration in the ≥ 3 lactation cows was higher than the second (13.45%; P > 0.05) and the first (28.28%; P < 0.01) lactation ones (28.28%; P < 0.01). The milk P4 concentration at the beginning of estrus and 12 hours after the beginning of estrus in pregnant and non-pregnant cows was 2.58 and 3.32; 4.20 and 5.00 ng/ml, respectively (P < 0.001). As a result, it was concluded that high progesterone concentration affected the expression of estrus and pregnancy results in dairy cows, and the measuring of progesterone concentration in milk can be used as a non-invasive method to provide detailed information about fertility in high milk yield cows.

Many researchers have pointed out that the intake of omega-3 and -6 fatty acids is beneficial to animal health and reproductive capacity, but the effect of fatty acids on the histomorphology of ram testes is still unknown. The aim of this study was to investigate the effect of linseed oil containing polyunsaturated fatty acids on the morphology and histomorphometric characteristics of ram testis and epididymis. Testes of 12 Lithuanian local coarse wool rams were investigated histomorphologically and histomorphometrically in the present work. The rams were divided into two groups, an experimental group and a control group following, the principle of analogues – the same origin, age, weight, and condition score. The experimental group (n = 6) received 2% linseed oil sediments while the control group (n = 6) received 1.2% sunflower oil for 9 months. The diameter of testicular tubules and the height of the germinal epithelium, the spermatogenic index and the number of Leydig cells were higher in the experimental group than those in the control group. In addition, the number of degenerated tubules was not significantly lower in the group that received 2% linseed oil sediments. Still, the height of the epididymal epithelium was lower than that in the control group.
