The purpose of this paper is to identify the extent to which the veterinary legislation of the European Union is complied with by a company from North-Eastern Romania. The parasitological analysis of the fish had as reference the EC Regulation no. 2074/2005, and the test result was negative. To measure the level of radioactivity, a 500 gram sample of "Alaska Froock Pollock File Code" was sent to the laboratory, the detected values being compliant. The same range of frozen fish was analyzed from a microbiological and physico-chemical point of view. After self-monitoring on five samples of 900 grams, Listeria monocytogenes was not present in fish meat (absent / 25 grams), and sulfite-reducing bacteria were within the specified standard value <1.0 x 10 cfu g. In the case of easily hydrolyzable nitrogen, the value of 29.13 mg / 100g was obtained, so below the maximum value of 35 mg / 100g. As a result of the analysis samples, it is found that the fish assortments studied correspond both from a physico-chemical, microbiological, parasitological, but also radioactive point of view.

Nutrients play a significant role for the environmental state of lakes, mainly because the primary production of lakes is strongly influenced by nutrient availability. From all these nutrients special attention is accorded to the total organic carbon (TOC), total nitrogen (TN) and the total phosphorus (TP). In this context, the aim of this paper was to determine the TOC, TN,and TP from the sediment and macrophytes samples from Horia Lake, Tulcea County, Romania. The lake is located in the area of Horia, being limited to the north, west, and south by the agricultural field. The slope of the ground allows the accumulation of the waters from the versants adjacent to the lake, with suspension contributions, fertilizers,and herbicides used for the adjacent corn crop. All the samples were collected in the autumn season (November 2016), from six stations of the lake. The results revealed significant differences (p˂0.05) in the concentration of the TOC, TN, and the TP. Comparing the means values of these nutrients from macrophytes and sediments, it can be concluded that the higher values from macrophytes are the result of the assimilation capacity of these nutrients.

Within the performance control activities of the skin production, for the analysis of the uniformity of the curls, we focus on the main characteristics that influence the expression and the externalization of a genotype with a certain type or form of curl with approximately equal values of the basic dimensions. To create conditions for genetic expression of the uniformity of the type of curls, it is necessary to follow the improvement of the following parameters: the length, the height, the width, the degree of closure, spiral direction, the contour and the distance of the curls on the skin surface. The method applied in the assessment of the specific characteristics of the research carried out was based on the technical norms specified in Section 1.4 and 1.5 of the MADR Order no. 22/20.01.2006, and the statistical processing of the data was based on the use of the computer program S.A.V.C. The obtained results show that between the average score determined for this character in the grayish variety and the black one, the difference is insignificant but the one between grayish and pink and grayish and grey is significant for P<0.01%, and the one between grayish and brown is significant for P<0.05. In the brown variety it is found that if at the first generation since the establishment of the breed register the proportion of those with maximum score was 46.33% at the generation evaluated in 2015, it is found that at almost 70% a good uniformity is obtained, resulting in a progress 2.35% genetically for each successive generation within that 10-year period.

The purpose of the research was to determine the level of improvement in skin production and how to express the strength and elasticity of curls. The importance of these characters is essential because both participate in shaping a certain type of curl that will have the quality of keeping the main shape and characteristics for a longer time. The biological material subject to appreciation belongs to the Karakul of Botoșani breed located in the Principal Class of the Genealogical Register. The experimental protocol was based on the assessment of the characters in three consecutive seasons and aimed at determining the degree of improvement of the curl for several selected characters. Based on the results, it can be concluded that the black variety average score is close to the maximum, thus indicating that the improvement of these characters is in a more advanced phase. Determining the degree of significance between the average scores for the gray and pink varieties are significant for P<0.01 and still significant for P<0.05 between pink and grayish.

The article describes the development and differentiation of the intermuscular and submucosal nerve plexuses of the large intestine of the fetuses of cows from 50 days of age to birth. On days 50-70, the muscular membrane of the intestinal wall is built from bundles of smooth muscle cells, clearly divided into inner (annular) and outer (longitudinal) layers. Ganglia are laid between them, forming the intermuscular nerve plexus. The submucous nerve plexus differentiates later. The development of the nervous apparatus of the rectal wall is ahead of the development of similar structures of the colon and cecum. Enhanced growth and differentiation of nerve cells in fetuses is noted from 95-120 days. The first synapse-like contacts were observed in the intestinal ganglia at the age of 4.5 months of embryonic development. Enhanced differentiation and growth of nerve cells of the submucous nerve plexus is observed in fetuses of a cow at 6-7 months. By the end of the embryonic period and in early postnatal ontogenesis, connective tissue gradually overgrows the developing ganglion of the colon wall. Before the birth of the fetus, the nervous tissue of the colon wall forms a complex intramural nervous system, represented by four plexuses - intermuscular, submucosal, actually mucous and sub-serous. There are a large number of mature synaptic contacts. The study examines the stages of morphological changes in the development of intestinal ganglia from the aggregation of neural cells to the formation of a complex intramural nervous system in the walls of the colon.

The Covid-19 pandemic period has spread across almost all countries in the world has resulted a significant negative impact on various socio-economic aspects, including on large-scale and small-scale livestock business activities. This paper aims to present a study of challenges in developing small-scale farms carried out at grassroots level communities affected by the Covid-19 pandemic in North Sulawesi Indonesia. The method used in this study was a meta-analysis pattern approach. The cases of covid-19 infection in this area began to emerge early on March of this year, where data until early May 2020 showed a number of people who were confirmed positive Covid-19 had reached 45 people. The government as an authority holder in North Sulawesi Province does not apply yet a lockdown. This temporary policy gives farmers the opportunity to move and continue developing their livestock activities in order to support the fulfillment of livestock products in local market, while on the other hand, feed row material tended to increase in the market. The recommendation to keep a physical distance did not significantly affect the activities to the small-scale animal farms because in general the workers were family who were the same people in a household.

The application of modern goat breeding systems implies the addition of the classical methods used to improve the genetic potential with methods of appreciation of the hereditary base and their productive capacity. The purpose of this paper was to highlight the particularities of the evolution of the body weight from birth to the weaning of the kids goat Carpathian and kids goat breeds (Saanen male and Carpathian female), established according to three main factors: parturition type, the sex of the kid goat and the status physiology of the mother goats. The study was conducted in a farm in the Trascău mountains area, locality Rimetea, county of Alba, during January-June 2019, where we monitored daily: the body weight and sex of kids goat at birth, type of birth and the age of the parturients. The working method consisted of daily monitoring and weighing the kids goat studied with an electronic scale with an accuracy of: 5 g (0.5 g-10 kg); 10 g (10-50 kg). The obtained results have been statistically processed, being beneficial in making faster and more efficient decisions in the selection and improvement process.

The present study was designed to evaluate if the use of a blend of commercial oils (BCO) obtained from different plants could affect growth performance and intestinal microflora of the gut in growing-finishing broiler chickens. A total of 80 Cobb 500, 14-day-old broiler chickens, with initial body weight 360 ±0.38g, were assigned to two groups, basal diet (C) and the basal diet supplemented (E) with 0.50% BCO. Throughout the entire feeding period (14-42 days), there were significant differences (P<0.05) in final body weight, daily weight gain, and for daily feed consumption (35- 42days), for group C compared with BCO. At 35 and 42 days, respectively, 6 chicks/group were slaughtered and samples of caecal and intestinal contents were collected for bacteriological examination. Weights of digestive organs including the liver, gizzard, intestine and pH from cecum and intestine were not affected by the dietary treatment. The colony forming units (CFU) of Escherichia Coli and Staphylococcus spp. in the digesta of caecum in the BCO group showed a significantly (P≤0.05) lower number compared with that in the C group. The CFU of Staphylococcus spp. in intestine was significantly (P≤0.05) lower in BCO group compared with C. Salmonella was absent in all cases. The inclusion of 0.5% BCO in the chicken's diet (14-42 days) it has reduced the proliferation of pathogen bacteria and has stimulated the increase of favourable bacteria like Lactobacillus spp. in the intestine and cecum of BCO group.

Rejected Laying Hen (RLH) meat has a low quality due to slaughtered at a relatively old age causing the tenderness of meat to be low and less desirable by the public. Improving nutritional quality and elevating the level of people's preference for chicken meat that have been done by innovating and diversifying into RLH, one of which was using boiled coconut water. The purpose of this study was to determine the effect of boiled coconut water on physical, chemical and organoleptic properties of RLH. The Completely Randomized Design Method with four treatments (boiling time of 15, 30, 45 and 60 minutes) with four repetitions was used as an observation variable which included physico-chemical tests (tenderness, cooking losses, water holding capacity (WHC), water content, protein content and fat content) and organoleptic tests. Physical-chemical and organoleptic tests of this study showed that there were significant differences in the duration of boiling. The range of cooking losses was 33.60 - 38.92%; tenderness value 5.54 - 6.13; and WHC ranges from 38.21 - 40.42. While the water content ranges from 67.26 - 69.09%, Protein ranges from 16.24 - 16.89%, and Fat ranges from 10.11 - 11.72%. Organoleptic test values range from 4.05 - 5.05. The conclusion of this study shows that the physical-chemical and organoleptic properties of RLH with boiling coconut water for 60 minutes have been able to maintain the quality of RLH and organoleptic tests were acceptable.
