Abstract

The aim of this study was to determine if reticulorumen ph, temperature and cow activity registered before calving can serve as indicators of diseases after calving.The cows were selected according to those fitting the profile of having had two or more lactations (on average 2.9±0.13 lactations), from 60 to 0 days before and the first 30 days after calving, and being clinically healthy. The clinical examination (identification of diseases after calving) was performed from 60 days before calving to 60 days after calving. Diseases after calving were diagnosed based on clinical symptoms specific to these diseases. The pH and temperature of the contents of the cow reticulorumens and cow activity were measured using specific smaX-tec boluses manufactured for animal care.We found that the highest pH and temperature before calving can serve as biomarkers of healthy cows after calving. The lowest reticulum temperature before calving can serve as an indicator of MF after calving. A positive correlation of reticulum pH and temperature before calving can serve as biomarkers of PR. Decreasing cow activity before calving can serve as an indicator of diseases after calving. For calving prognosis, temperature of the reticulorumen can be used; it decreased 6–7 days before calving.

Abstract

The objectives of this study were to examine the option of being able to use rumination time (RT) as a form of stress indicator in the first thirty days after calving, and to determine the relationship between rumination time, blood cortisol levels, and lactate concentration levels in dairy cows during the first thirty days after calving. Ninety cows which produced milk (DIM) within 1-30 days were selected and categorised into the following groups: the first group (1) fell within 1-7 days after parturition (dpp) (n=30); the second group (2) fell within 8-14dpp (n=30); and the third group (3) fell within 15-30dpp (n=30) after calving. The cows were milked using Lely Astronaut® A3 milking robots with free traffic. The blood samples were tested using the fluorescence enzyme immunoassay method for cortisol analysis. Lactate concentrations were tested with a Lactate Pro2 ®. The RT increased during all of the exploratory periods (with readings between 1.12-4.90%). A decrease was also observed in the lactate levels (by 1.10 times) and cortisol levels (by 1.98 times, p

Abstract

The objectives of these studies were to examine the option of using automatic health tracking systems biomarkers as a form of stress indicator and to determine the relationship between biomarkers, blood cortisol levels, and lactate concentration. Ninety cows within 1-30 days were selected and categorized into 3 groups: group 1 - 1-7 days after parturition (dpp) (n = 30); group 2 - 8-14 dpp (n = 30), and group 3 - 15-30 dpp (n = 30) after calving. The cows were milked using Lely Astronaut® A3 milking robots. The pH and temperature of the contents of cow reticulorumen were measured using specific smaX-tec boluses manufactured for animal care. The blood samples were tested for cortisol, lactate concentration. Data about rumination time (RT), milk yield (MY), milk composition, milk somatic cell count (SCC), milk electrical conductivity (EC), consumption of concentrate (CC), weight (BW) were collected from the Lely T4C management program. The RT increased during all of the exploratory periods (with readings between 1.12%-4.90%). A decrease was also observed in the lactate levels (by 1.10 times) and cortisol levels (by 1.98 times, P < 0.05) of cows in group 2 (8-14 dpp) compared with an average of group 1 (1-7dpp) in the previous study period (15-30dpp). However, lactate concentrations increased (by 1.84 times, P < 0.05) as well as cortisol levels (by 2.09 times, P < 0.01) when compared with group 2 on average. The results obtained indicate that RT increased during all exploratory periods, while a decrease of 1.10 times and 1.98 times was observed in lactate levels and cortisol levels, respectively. RT positively correlated with the lactate concentration levels and negatively correlated with cortisol levels during the entire study period. According to this study, there was a positive correlation with milk lactose (ML) during stress, which tends to increase the risk of mastitis and decrease CC, RT, BW, MY, reticulorumen ph, and fat/protein ratio F/P.

Abstract

Despite wide spread advances in veterinary of diagnostic and therapeutic applications, bovine respiratory diseases continue to cause enormous economic costs. The aim of this work was to analyze the main causes of respiratory system diseases in the selected farm and the methods of treatment of these diseases, to make a farm prevention plan. Twenty calf blood samples were analyzed, which were collected using sterile needles from the jugular vein by vacuum tubes (v. jugularis) and sent to the laboratory of the Large Animal Clinic for blood morphological and biochemical analysis. Serological samples were sent to the National Food andVeterinary Risk Assessment Institute, where the antibodies and ntigens of the virus were detected by the IFA method. A control (n = 10) and research (n = 10) group were formed. The following features were considered in the study group: temperature >39⁰C, cough, nasal and ocular liquid, decreased activity, appetite. According to blood morphological and biochemical measurements, statistically significant were determined for RDW, Fe, Glu at p

Abstract

The hypothesis of this study was that there were changes in biomarkers registered by innovative technologies in cows with subclinical acidosis. The aim of this study was to identify changes in the in-line milk fat-to-protein ratio and cow feeding behaviors such as reticulorumen pH, reticulorumen temperature, cow activity, and water intake with subclinical acidosis. From a total of 98 cows, 59 cows were selected to meet the following criteria (2 or more lactations, with 31 days in milk (DIM)). The selected animals were separated into two groups based on general clinical examination and reticulorumen pH: the subclinical acidosis group (SCA, n = 23) and the healthy group (HC, n = 36). During the diagnosis of subclinical acidosis and following the clinical examination of the healthy group using the BROLIS HerdLine system, the daily averages of milk yield (kg/day), milk fat (%), milk protein (%), and the milk fat-to-protein ratio were recorded. Simultaneously, by using Smaxtec technology, reticulorumen parameters and cow activity, including pH, temperature (°C), rumination time (minutes/day), and water intake (hours/day), were registered. Changes in parameters measured using innovative technologies were able to identify cows with subclinical acidosis. Cows with subclinical acidosis had a lower reticulorumen pH by 18.8% ( p < 0.0001), a decreased milk yield by 10.49% ( p < 0.001), a lower milk fat-to-protein ratio by 11.88% ( p < 0.01), and a decreased rumination time by 6.59% ( p < 0.01). However, the activity of these cows was higher by 57.19% ( p < 0.001) compared to healthy cows. From a practical point of view, we suggest that veterinarians and farmers track parameters such as reticulorumen pH, milk yield, milk fat-to-protein ratio, rumination time, and activity for the identification of subclinical acidosis.
