The paper concentrates on researching the possibilities of using modern information technologies in animal production in order to monitor and identify behavior and well-being of cows. Having in mind the challenges related to managing dairy herds, and economic pressure put on breeders (as well as the broadly defined well-being of animals), an endeavor was made to create a new method, which would be competitive in comparison with the existing solutions. The proposed method of collecting data and data processing with beacon devices as well as data warehouse, allows—according to the authors—a more complete identification of behaviors and physiological condition of a dairy herd. It is also worth pointing out that this method is competitive in terms of price. By virtue of the multitude of data that were collected, a decision was made to resign from processing data on a local computer and use a cloud compute engine instead. The presented information system creates a sequence of components, which were subject to verification both on the level of creating and conducting research. Research results that were received were then compared with knowledge presented in the literature. A vital element of validation of the aforementioned methodology was comparing results that were achieved in the course of research work with the system making use of pedometer. The aim of the authors was to develop a new information technology solution, as well as a method based on beacons, which are rather universal devices, with the use of data warehouses, allowing the identification of behavior and physiological state of milk cattle, the method which would be competitive in comparison with the existing solutions, especially in terms of price. In the proposed solution, both information coming from microcomputers and weather forecast data coming from weather forecast stations, which make the above identification easy, were used as data sources.

The materials on the study of the feed additive Abiotonic in rabbit breeding, as well as the results of organoleptic, microbiological, histological studies and the amino acid composition of rabbit meat of the New Zealand white breed are presented. According to the results of the studies, there was no negative effect of the feed additive on the veterinary and sanitary indicators of rabbit meat, the carcasses were well bled, drying crusts were formed in a timely manner, the muscles were elastic, light pink, white fat, the broth was clear and aromatic. No pathogenic and conditionally pathogenic microflora were found. At the same time, it was noted that the feed additive contributed to the increase in meat of non-essential amino acids by 6,01%, essential amino acids by 9,74%, which increases the biological value of the product. According to histomorphological studies, the Abiotonic feed supplement did not adversely affect the physiological state of animals, muscle tissue and internal organs developed within the physiological norm of rabbits.

Abstract Histopathological examination of liver, kidney, spleen, pancreas, duodenum, jejunum, skeletal muscle, and bursa of Fabricius samples, collected from broiler chickens, laying hens, fattening pigs, and calves fed genetically modified corn MON 810 and soybean meal MON-40-3-2 (Roundup Ready, RR), was performed The examination showed no significant differences between the control animals fed diets containing no genetically modified feeds and animals fed genetically modified feeds. In some cases, congestion of parenchyma and focal lymphoid cell infiltrations were observed in all dietary groups, including controls, and therefore, it was assumed that the lesions were not associated with the feeding transgenic feeds.

The purpose of the research is identification of the current parasitological situation for Eurasian beavers inhabiting the Central Russia.Materials and methods. The work was carried out on hunting farms and in specially protected areas of the Central Russia. Potentially infective material was collected, recorded and preserved from animals during 2015–2021. The age of the animals was determined by their weight and physiological state of the rodents’ teeth and internal organs, and the sex was determined by their genitals. The animals were examined according to the method of complete and partial helminthological dissection per Skryabin.Results and discussion. A total of 41 animals were examined. Three forms of parasitism on animals were identified in natural habitat, namely, the trematode Stichorchis subtriquetrus, the nematode Travassosius rufus, and the ectoparasite Platypsyllus castoris. The stichorchosis causative agent localized in the animal’s large intestine was diagnosed in 35 rodents (85.4%). The helminth infection was 96% in the Eurasian beaver and 68.7% in the Canadian beaver. The nematode infection in stomach was detected in 31 animals (75.6%). The infection by T. rufus was 88% in the Eurasian beaver, and 56.3% in the Canadian beaver. The infected animals were delivered from the Vladimir, Moscow, Ryazan, Tula and Yaroslavl Regions. The beaver beetle P. castoris was found in 6 animals (14.6%). The infection rate was 8% in the Eurasian beaver, and 25% in the Canadian beaver. Animals with wingless arthropods have been identified in the Moscow and Ryazan Regions.

AbstractA 14-d study was undertaken to test the acute toxicity of a new preparation Vetom 21.77 based on the predacious fungus Duddingtonia flagrans. A total of 40 healthy 5-day-old broiler chickens (Hubbard F15, 100 ± 5 g), that had previously gone through a required 5-days adaptation to the environment, were orally dosed with the drug for 5 consecutive days at different doses, after which their health status was assessed daily up to the end of the experiment. According to the results, no substantial changes in the physiological state of the chickens were detected during the experiment. Internal organs weighing revealed no statistically significant differences between the groups, though weight coefficient values of internal organs of treated chickens slightly exceeded those of the control group. Some haematological parameters were significantly higher in the treatment group, without going beyond reference ranges. All chickens used in the experiment survived the study. The preparation has not produced any toxic effect even at a higher dose (4000 µL/kg bw/day). It is concluded that Vetom 21.77 pertains to preparations of IV toxicity class.

In a study of youthful slaughter cattle comprising 168 steers, 147 heifers and 259 bulls, minor but statistically significant (P < 0.05) sex differences were observed for percent hide, shanks and head (steers > bulls > heifers) and percent kidney and cod or udder fat (heifers > bulls > steers). Bulls dressed approximately 1% higher and heifers 1% lower than steers, these sex differences apparently arising from items not recorded on the killing floor (including blood, lungs, digestive tract and contents and reproductive tract of females). Sex differences, particularly the bull versus steer comparisons, may have been influenced by differences in breed and/or pre-test treatment. Percentage internal fat trim and unrecorded slaughter loss were positively, and percent head, hide, shanks and internal organs negatively, correlated with liveweight at slaughter. However, slaughter weight accounted for less than 5% of the variance in dressing percentage, and age independent of slaughter weight had little influence on any of the traits studied. Total recorded slaughter loss expressed as a proportion of carcass weight decreased 0.1 to 0.4% per 100 kg increase in slaughter weight. The importance of pre-slaughter shrink in determining total slaughter loss was discussed.

Friesian Cows

SummaryThe influence of physiological state (pregnant, lactating, dry) on body composition and fat partitioning in Friesian cows has been examined. A total of 20 cows, four per physiological state, were slaughtered and their left half carcasses dissected into individual muscles, bones and fat depots. All body parts, including the internal organs and fat depots, were weighed at slaughter.Muscle tissue and the internal organs showed some weight changes, consistent with a redistribution of tissue towards the udder and gut, and mobilization of muscle, but the major changes in weight associated with changing physiological state occurred in total body fat.Intermuscular fat made the greatest absolute contribution to changing fat weight, but subcutaneous fat showed the greatest proportional change with changing physiological state. The order of depletion of fat depots during fat loss was approximately the reverse of the order of development found during developmental growth.The distribution of subcutaneous fat between seven defined regions of the carcass was not affected by differences in total fatness in different physiological states. This, and the high correlation found between fat depth and total body fatness, confirms the view that measures of subcutaneous fat depth, e.g. by ultrasonics, should be useful predictors of the energy status of cows in varying physiological states.

This study presents the results of investigation of anti-adhesive properties of the dura combined with polypropylene implant, and a composite mash with a hydrogellayer Parietex Composite. 40 Wistar rats were used for this research work. The study showed that the use of the dura as an anti-adhesive coating prevents fusion of the internal organs with the implant, and the polypropylene used as a mash basis, firmly fuses with the parietal peritoneum, promoting in growth of connective tissue in the grid structure. These results are comparable to results obtained using Parietex Composite.

Fattening and slaughter value of fattening pigs and the dietetic properties of pork depend, among others, on sex, breed, crossbreeding scheme, and age and body weight at slaughter (Weatherup et al. 1997). The degree of carcass meatiness and meat quality depend largely on the breed of the crossed boars (Davey and Bereskin, 1978). The aim of the present experiment was to analyse the effect of crossbreeding, slaughter weight and feeding on the slaughter value and meat quality of fattening pigs.

Abstract The objective of the study was to analyse selected physical properties and chemical indicators of internal organs obtained from fattening pigs and Central European wild boars (Sus scrofa scrofa). Each group consisted of 12 animals. The tongue, heart, lungs, liver and kidneys were examined for physical properties, basic chemical composition, macro- and micromineral content, and fatty acid profile. The atherogenic index (AI) and the thrombogenic index (TI) were also determined. Pig offal was found to be a rich source of protein and collagen, and to contain large amounts of potassium and sodium. Liver had a high content of iron, zinc, and manganese. Pig liver and wild boar heart were characterised by favourable PUFA /SFA ratios (above 0.4%). In addition, the content of neutral and hypocholesterolemic acids (DFA ) and hypercholesterolemic acids (OFA ) in pig offal was comparable to that in pig meat. The results presented in this study provide an extensive evaluation of the nutritional quality of pig offal, which allows an increase in the scope of its use in the food industry, among others for production of offal products, including traditional and regional products that are increasingly demanded by consumers.
