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 goal of this study is to estimate the effects of low-level laser irradiation (LLLI) on the superovulatory response according to the number of corpora lutea (CL), follicles (F) and the embryo yield. In recent years, while searching for new, more efficient and organic methods to improve superovulatory response and embryo yield with respect to the conventional methods, low-level laser irradiation (LLLI) is a more sensitive and less costly technology that can be used to improve animal reproduction, namely, artificial insemination and the embryo production system. The dairy-cow donors were treated for superovulation with PlusetR, at any time during the oestrus cycle, and the total dose per donor was 700 IU. The first group of the donors (n=25), test group (TG), was irradiated on the sacroiliac area for 180 seconds per day, from the 1st to 11th superovulatory treatment (ST) days in a row, with LLLI in the 870-970-nm wavelength, 65.93 J/cm dose, frequencies in the 20-2000 Hz range and pulse durations commonly in the range of about 1 second. For the second control group (CG) (n=25), the ST was performed without LLLI. After the ST, The mean number of CL in the right side ovaries in the TG was 25.43% (p<0.05) greater than in those of the CG. The number of total recovered and transferable embryos was greater in the TG compared with the CG by 28.97% (p<0.05) and 15.8% (p>0.05), respectively. With respect to conventional methods, LLLI can be used to improve the superovulatory response and embryo yield as a supplementary environment and animal-friendly method of treatment.

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.
