This study aimed to identify whether the silkworm pupae (SWP) added to pigs' diets can be considered a valuable protein-rich alternative source. The silkworm (Bombyx mori L.) and its by-products are highly valuable in terms of nutrition, medicine, and commerce. The SWP is the main by-product of the sericulture, considered a well‐balanced source of nutrients in terms of proteins, lipids, minerals, vitamins and various bioactive substances such as fatty acids, peptides, and polyphenols with antioxidant, anticancer, cardiovascular, hepato-protective properties. The mulberry silkworm's potential for use in human food has been previously extensively documented, whereas the preponderance of literature data on SWP used in the livestock industry specific focus on poultry. There is limited pig-related data. In this study, we reviewed the most recently published papers on PubMed, Elsevier, MDPI, and Research Gate, using the keywords "silkworm pupae", "composition", "protein", and "pigs". We did not find any negative consequence on pigs' growth and health parameters in the reviewed published data.

The evolution of modern technologies for preserving fish and fish products has led to the eclipse of the preservation properties of many traditional methods, including the smoking method. Nowadays, the main purpose of smoking has been redirected towards highlighting the sensory quality rather than its preserving effect. The main aim of this paper is to highlight the physicochemical, sensory, and color characteristics of smoked phytophagous fillets. To produce the necessary products, nine specimens of phytophagous (Hypophthalmichthys molitrix) were harvested from the fish farm "Piscicola Vlădeni, CC&C PES SRL" Iasi, which were processed and prepared in the Microproduction Workshops of the Iasi University for Life Sciences "Ion Ionescu de la Brad". Three different smoking methods were applied to the fillets resulting from the phytophagous processing; hot smoking, semi-hot smoking, and cold smoking. From a physicochemical point of view, in the case of the batch with hot smoking quantity, a lipid content of 1.76±0.024% was recorded, higher compared to the L2ASC (0.94±0.04%) and L3AR (0.86±0.024%) batches. As regards protein content, the highest value was also found in lot L1AC (22.2±0.083%), followed by lot L2ASC (22.18±0.02%), with the lowest value in lot L3AR (21.96±0.024%). The most appreciated fillets were those processed by heat treatment with semi-warm and warm smoking.

The study of the formalized characteristics’ effect of the spatial location of milking equipment, cows and operators in connection with the time spent on working operations is presented. The material for the research was timekeeping of the milking process using different equipment. It has been established that the correlation coefficient between the length of the working area for milking and the duration of the working operation "transition between animals and equipment" is r=0.330 (p<0.001). The measure of effect size of milking trench's presence/absence factor on the time spent by the operator on milking 1 cow was η2=0.779 (p<0.001). The time when the machine milking operator stays in a position with a strongly bent torso (over 40°) during milking using a trench is almost 50 times less (p<0.001) compared to the corresponding time during milking without using a milking trench. When working in the trench, the operator does not perform working actions in the "squatting" position at all. If milking occurs in stalls, then a small distance between adjacent cows makes it difficult for the operator to access the udder.

The main objective of the research carried out, was to determine the impact due to additional feeding on the specific performance of milk production in Botoșani Karakul sheep breed. In order to achieve the main objective of the research, two groups of adult females between three and six years of age were formed. Both lots were maintained under similar conditions, applying a traditional technology based on feeding them from the stock during the cold season and on pasture during the warm season. The experimental treatment was represented by the fact that L2 benefited from additional feeding applied 25 days before the mating date. This batch received a 170 g amount each morning consisting of a mixture of cultivated cereals (ground corn, sunflower meal, barley and oat grains). Live weight and body condition evaluation at mating time indicates a 2.41 kg higher live weight at L2 but also an improvement in body condition by 0.31 points. For live weight, a significant difference between groups was obtained for P≤0.05. Regarding the milk production obtained from the females in relation to the BCS assigned to L1 the biggest difference was between BCS = 3.0 and BCS = 1.5 and in L2 between BCS = 2.5 and BCS = 1.5, both situations being significant for P<0.01.

During the period 2019-2021, the helminth fauna of two species of freshwater fish of the family Cyprinidae, genus Ballerus Heckel, 1843 - white-eye bream (Ballerus sapa (Pallas, 1814)) and zope (Ballerus ballerus (Linnaeus, 1758)) were examined. Six specimens of white-eye bream and one specimen of zope were collected from a total of three biotopes located in the Bulgarian section of the Danube River between 845 and 807 river km. Three species of helminths were found - 2 species of the class Trematoda (Asymphylodora imitans (Mühling, 1898) Looss, 1899; Nicolla skrjabini (Iwanitzky, 1928) Dollfus, 1960)) and 1 species of the class Nematoda (Contracaecum sp. (larvae)). The present study aims to provide new data on the species composition and helminth ecological indices of the two examined fish species. B. sapa is reported as a new host record for the three helminth species in Bulgaria. Koshava biotope is a new habitat for the established helminths in the white-eye bream.

Data is presented from 140 records of pregnancies and births of goats of the Anglo-Nubian breed, bred in the farm of the Research Institute of Mountain Stockbreeding and Agriculture - Troyan, Bulgaria. The data was used to determine the influence of sex, type of delivery and parity on the gestation length (GL) in goats. The delivery season is not taken into account, as it is always in the winter. There was a significant difference in the GL of goats that gave birth to singles and twins (p<0.001). The GL for all kids born as singles was 151.1±0.4 and twins 149.2±0.3 days. No significant difference was observed between the GL of goat that gave birth to male (151.2±0.7) and female (151±0.6) singles. A difference of more than one day was found between the GL of goats that gave birth to male and female twins (148.2±0.6 and 149.9±1, respectively). The GL in goats that gave birth to twins of different sexes was 149.4±0.4 days, and in goats from the first to the fifth parity (149.2±0.6; 149.9±0.5; 149.0±0.6; 150.5±0.6; 150.9±0.7 days) respectively.

Farmers receive subsidies from the state and an assessment of the living standard in the respective nation can be made based on the dynamics of cattle livestock and the development of dairy products. The EU Council receives data on these issues from EU nations each year.The data processed in the study were collected from the Annual Statistical Surveys. The data came from about 600 economic operators but summative data organization and presentation techniques (descriptive statistics) were used for processing. In Romania, during the analyzed period, even though the cattle herd decreased by 8.01%, milk production increased by 15.91% from 2016 to 2020, as farmers were interested in exploiting genetically valuable specimens. Butter production followed a sinusoidal trajectory, increasing in 2017 (177 tons), decreasing by 12 percent until 2019, and then increasing by 14.33 percent in 2020. Cheese production followed an upward trend ranging from 1 to 5.68 percent, with the highest determined increase (5 127 tons) in cheese production for 2018 compared to 2017.

The research proposed to evaluate the influence of the seminal material on milk production. Also was studied seminal material from different countries in order to determinate if the origin influence as well, genotype - environment correlation. The study was carried out on Holstein cows from Romania and data provided by Holstein Ro association. For sires values were consulted international website, recognized worldwide, like dairybulls.com, where the data are published by CDCB (Council on Dairy Cattle Breeding) or INTERBULL. The cows that took part at the research were all at their first lactation, from farms located throughout Romania. After establishing the groups of contemporaries, the real production achieved on standard lactation was compared with the surplus amount of milk due to the sire’s values, in order to see if the expected result was achieved. For avoiding error conclusions were compared cows from the same farm, same sire, in that working hypothesis the feeding influence is removed.

The milk consumption has increased constantly, with milk being part of the diet of a large proportion of the global population. As a result of this growing demand, the increased competition in the dairy market and the increasing complexity of the supply chain, the producers in the sector of milk and dairy products resort to technological fraud, which is considered to be a predominant problem in countries without a specific legislation. Therefore, this paper aims to review the main adulterants, the counterfeiting techniques and various methods of detecting counterfeiting.
