This study is the first to reveal the helminth fauna and helminth community’s structure of Prussian carp (Carassius gibelio) from Maritsa River, Bulgaria. In 2022, ten Prussian carp specimens were collected from the Maritsa River and examined for parasites. 90% of the studied hosts harbour parasites. Two species of helminths were fixed: one from class Acanthocephala (Acanthocephalus anguillae Muller, 1780) and one from class Nematoda (Pseudocapillaria tomentosa Dujardin, 1843). The established nematode species is distinguished with high prevalence. Carassius gibelio is reported for the first time as a host for Pseudocapillaria tomentosa in Bulgaria. The river ecosystem of Maritsa is a new locality record for Pseudocapillaria tomentosa in Bulgaria.

The purpose of this paper was to highlight the results of biometric measurements were performed on cattle of the Aubrac breed, exploited in Romania. Were measured a total number of 84 bovine, both adult females and bulls (12-18 months), in three farms in the region of Moldova. The highest recorded average for biometric parameters was: height at the withers (133.23 cm at females, 130.24 cm at bulls); rump height (140.78 cm at females and 130.46 cm at bulls); chest girth (202.15 cm at females and 204.22 cm at bulls); slantwise body length (159.64 cm at females, respectively 161.22 cm at bulls). Body conformation indices were calculated based on the obtained values. Cattle exploited within farm 2, show the most pronounced massiveness. Weight values between 553.21 and 603.13 were recorded in adult females and between 551.89 and 618.82 in bulls. As a general conclusion, we can state that the animals taken in the study, exploited in the three farms, present overall reports that denote a well-proportioned body development, within the specific morpho-productive type.

The purpose of the work was to evaluate the influence of a mannoprotein extract (MP) from brewer yeast on the motility, speed, as well as the morphological and microbiological indices of the ram semen preserved by refrigeration at +4°C. The experimental extender (EE) supplemented with MP at the concentrations of 0.6-0.9% v/v significantly increased (P≤0.05) the total motility (TM) and the progressive motility (PM) of ram spermatozoa during 96 hours of storage and did not negatively influence the VAP, VSL and VCL indices. At the end of the 96-120-hour period of storage MP in the concentrations of 0.8-1.0% v/v contributed to reduction of the abnormal sperm (AS) number as compared to the control extender (CE). EE with MP in the concentrations of 0.2-1.0% v/v significantly reduced (P≤0.05) the contamination of the semen samples with various microorganisms. The obtained results demonstrated perspectivity of the yeast extracts for effective semen dilution and preservation for further artificial insemination (AI) of animals.

The paper deals with the study on individuals of two groups of cows, of red-white, wide-faced Montbeliarde and Simmental cattle breeds approved in Bulgaria according the qualities of their hoof horn and the impact of exogenous and endogenous factors on this process. Visual, metric and anatomically-topographical methods were used. Five measurements were made of the following indicators: length, width, total width, height and hoof angle of the thoracic and pelvic limbs of the studied animals during the indoor and pasture periods. Support point in cm² and the ratio of 1 kg live weight to unit support point in cm² were calculated. Pasture-raised cows, in both breeds, showed a higher coefficient (ratio) of a unit of support point compared to live weight, respectively a coefficient of 1,7576 for Montbeliarde breed or by 8.2% more and a coefficient of 1,3946 for Simmental breed or by 9.1% more. Mobility of cows affected critically to their ongoing health, productivity and longevity. Uniform growth of the hoof horn was determined by the equal distribution of cows’ body weight over the distal limbs. Hoof growth was subject to seasonal fluctuations.

The essential aspects in choosing pet food are the quality and nutrient content of the food. This becomes difficult for pet owners to manage when many diets or types of dogs and cat food are available on the market as will be mentioned in the study: commercial pet food, BARF (Biologically Appropriate Raw Food), home-made or vegetarian diets. There are also many brands and recipes in the commercial pet food industry, which again causes confusion and misleads pet owners. Pet owners now treat their dogs and cats as family members, which is why studies show that globally owners have become more aware of their pets' needs. The current study attempts to present the benefits and drawbacks/disadvantages of different varieties of dog and cat food. By providing an overview of pet feeding patterns, the study seeks to clarify the nutritional needs and highlight the physiological digestive capabilities of two specialized carnivores: the dog and the cat.

The aim of this study is to achieve a comparative analysis of the cow livestock number, production of milk and of main dairy products in Romania and European Union. The work is an extensive bibliographic documentation with the application of statistical tests for the period 2017-2021. At European Union level the herd of dairy cows is in decreasing with 5.63% and in Romania with 7.95%, from 1175.4 thousand heads in 2017 to 1081.9 thousand heads in 2021. The largest amount of raw milk available on the farm in 2021 belongs to Germany which records 32531.56 thousand tons, approx. 21% of the total quantity at EU level. In 2021 compared with 2017, the Europeans consumed with 3.91% less fresh dairy products and with approx. 5% more cheese. In the future, will be exploit more productive animals, making cow rearing a part of solutions in food crisis.

The scientific research done in the past few years has been conducted with the aim of discovering and developing new materials and technologies to develop foods that are healthier and more valuable nutrition-wise. The new generation of products should be in accordance with the environmental directives, sustainable, should do no harm, and should also ensure equitability of the market. Among the unconventional materials that caught our attention, chestnuts and rosehips are sustainable, underexploited resources that meet dietary and nutritional requirements. The aim of this paper is to gather comprehensive knowledge and get an overview of the use of chestnut flour and rosehip powder in different value-added food products, and to identify the possible gaps in the current knowledge. This work will help the further research in the field of valorization of chestnut and rosehip, and therefore, contribute to the development of innovative functional food formulations. Moreover, this matter is of importance because the generation of novel products would meet consumer expectations and will both help generate income to the food industry and provide a more sustainable use of resources.

The present study was carried out to follow the technological manufacturing process of functional meat products - three batches of pork tenderloin injected with sea buckthorn oil in three different proportions of 1, 3, and 5% and to analyze their quality. The products were obtained in the Meat and Meat Products Microproduction Workshop of the University of Life Sciences Iasi. After the experimental batches were made, their sensory and physical-chemical analysis was carried out. The sensory analysis of the three types of muscle injected with sea buckthorn oil involved the application of a CATA questionnaire to a group of evaluators, which showed that these products have good consumer acceptability, especially the 3% and 1% sea buckthorn oil batches. The physicochemical aspects were analyzed in terms of color, pH, and raw chemical composition. The colorimetric analysis showed a decrease in the brightness of the samples with an increase in the amount of sea buckthorn oil in the batch. As for the chemical analysis, the increase in the amount of sea buckthorn oil resulted in very different values between batches.

The efficient breeding of dairy goats depends on the quality of the breeds and the number of high-producing animals, but it also depends to a large extent on the fertility of the goats, their ability to reproduce offspring with normal reproductive functions. Although goat research worldwide is older and more developed than in Romania, information on this species has been limited for a long time, as most research institutes have presented their results jointly for small ruminants, especially sheep and goats. Artificial insemination (AI) is an assisted reproductive technology that involves the manual placement of semen into the female's reproductive tract through means other than natural mating. This method facilitates the meeting of gametes, namely sperm and oocytes, resulting in the formation of offspring. The conventional method for artificial insemination (AI) in sheep and goats in Romania involves the use of fresh or chilled semen, which has provided satisfactory fertility outcomes. The implementation of genetic enhancement techniques and the utilization of imported semen that meets safety standards, necessitating the use of cryopreservation, have the potential to significantly improve milk yield. The objective of this study was to examine the dynamics of artificial insemination (AI) in goats within Romania and to generate a short-term forecast regarding the utilization of this biotechnology in the country's farming conditions. The analysis of the forecast data indicates a positive trajectory in the quantity of AI within the time frame of 2022 to 2026. Specifically, it is anticipated that the number of AI will rise from 2956 in 2023 to 3603 in 2026, signifying an approximate 18% increase. The upper confidence limit suggests that the range of AI could potentially reach between 4310 in 2023 and 6311 in 2026.

For the period 2019-2021, three fish species of the family Cobitidae, caught from the upper section of the Danube River in Bulgaria, were subjected to ecologohelminthological investigation. Four specimens of Cobitis elongata Heckel & Kner, 1858 (two specimens from Kudelin biotope and two from Koshava biotope); six specimens of spined loach (Cobitis taenia Linnaeus, 1758) (from Koshava biotope) and one specimen of Sabanejewia bulgarica Drensky, 1928 (from Kudelin biotope) are objects of research. The trematode Asymphylodora tincae (Modeer, 1790) Lühe, 1909 was reported for the first time as a helminth of S. bulgarica. The nematode Pseudocapillaria tomentosa (Dujardin, 1845) Moravec, 1987 was reported for the first time as a helminth of C. elongatа. Kudelin and Koshava biotopes are new habitats for the found helminth species. During the helminthological examination of C. taenia, infection with helminths was not found. The study provides new data on helminth fauna and ecological indices (MI, MA, and P%) in the helminth communities of C. elongatа and S. bulgarica.
