The purpose of the paper was to examine weight loss and correlation between total bacteria count and the somatic cells count and weight loss of semihard naturally dried cheese, product of dairy plant ZZ?Cijevna? in Podgorica. Weigt loss was calculated on the base of difference in mass of cheese at the beginning of ripening and after specified period of ripening, exposed in percents. Examination of weight loss was done on total six product series of cheese during 60 days of ripening on temperature 14,20C and RH of 89%. Obtained average values for weight loss of cheese were: after 10 days 4.723%, 20 days 8.789% and after 30 days of ripening 11.020%. Weight loss of cheese in period of ripening 10-20 days was 4.266%, in period 20-30 days 2,445% and in period of ripening 30-60 days 5.507%. The total bacteria count in milk was determined on apparatus BactoScan FC 100 and the somatic cells count on apparatus Fossomatic 5000. The middle positive correlation between somatic cells count in milk and weight loss of cheese in period 1-10 days of ripening (0.69156), as well as middle positive correlation (0.767336) between total bacteria count and weight loss of cheese 1-10 days of ripening were determined. The obtained results show that weight loss of cheese was highest in period 1-10 days of ripening and that there is significant influence of hygienic quality of milk on weight loss of cheese and economy of production.

Quality Of Milk

For animals the sense of physical comfort is necessary (physical comfort). When animals feel physically comfortable, it means that every part of their bodies is in harmony with the surrounding area. Therefore, the farms are usually build in accordance with the number of cattle that will be hold in designed facilities, which provide a higher degree of cows cleanliness. Cleanliness of cows is important in order to produce hygienically clean milk and to achieve the cattle welfare of dairy cows too. Cleanliness of animals mostly depends on what kind of object they are placed in. Hygienically proper milk includes the number of microorganisms up to 100,000 / ml and the number of somatic cells to 400,000 / ml, which are regulated by the "Regulations on quality of fresh raw milk." For this research farms are divided into three groups according to the number of cows. The first group included the number of cows from 1 to 9, the second group included 10 to 19, and a third group 20 or more cows. The aim of this paper is to examine whether there is an influence of the size of farms (number of cows) on the subjective cow cleanliness and hygienic quality of milk.

Main Factor

The main factor of determining the level of sanitary and hygienic indicators of the quality of milk produced is the hygiene of milking cows. The study of the role of hygiene of milking is of great importance for a correct understanding of the ways of solving the problem of obtaining high quality milk. Special attention of scientists and practitioners in recent years are focused on the development and implementation of highly effective detergents and disinfectants in the production of milk of cows. Many researchers and practitioners have directed their work to developing measures to prevent the entry of pathogenic microflora into milk during and after milking cows. In spite of many researches carried out, aimed at controlling the number of somatic cells in milk with the use of different products based on lactic acid, chlorhexidine and iodine, the problem of high quality milk production remains unresolved. In our work results of researches on the use of probiotic means for treatment of udders of cows are given. Processing the udder of cows with probiotic means before milking by Skin Cleaner, after milking by PIP Cow Teat Cleaner reduced the amount of somatic cells in cow milk 12,8-84,0%. The use of probiotic means Biomastim lowed somatic cell count of 18,4-51,9%. Microbiological contamination of milk using probiotic means for processing the udder before milking Skin Cleaner, after milking PIP Cow Teat Cleaner decreased 4,9- 70,4 times. The application of probiotic means Biomastim after milking on the teats led to the decrease in milk of cows QMAFAnM 5,0-6,6 times.

INTRODUCTION: Obesity is related to numerous negative consequences for physical and mental health. It is often associated with the presence of binge eating disorder, body image dissatisfaction, and general psychopathology. OBJECTIVE: To assess the effects of an interdisciplinary lifestyle therapy on binge eating symptoms, depression, anxiety, body dissatisfaction, and quality of life in obese adults. METHODS: A total of 49 obese adults (body mass index = 37.35±5.82 kg/m²; age = 44.14±10.00 years) participated in a weight-loss program for 6 months. Symptoms suggestive of binge eating, body dissatisfaction, depression, anxiety, and quality of life were measured using self-reported questionnaires. Food intake was assessed using a 3-day dietary record. Data were analyzed using analysis of variance (ANOVA). RESULTS: ANOVA results showed a reduction in binge eating symptoms and in body dissatisfaction results. Depression and anxiety symptoms also decreased, and an increase was observed in quality of life scores. After therapy, a significant improvement was observed in dietary patterns, as well as significant weight loss. A positive correlation was found between variation of anxiety symptoms and lipid intake. Binge eating symptoms were associated with anxiety symptoms and body image dissatisfaction, and body image dissatisfaction correlated positively with anxiety symptoms in males only. In females, a positive correlation was observed between depression and binge eating symptoms. CONCLUSION: The interdisciplinary therapy was effective in promoting positive physical and psychological changes and in improving the quality of life of obese adults.

Interpretation Of Results

The view that resazurin is not a satisfactory substitute for methylene blue in assessing the hygienic quality of milk has been examined.Resazurin is equally as sensitive as methylene blue to the metabolic activities of bacteria in milk. It is decidedly more sensitive to the presence of non-bacterial factors in abnormal milks (mastitis, late lactation, etc.) and therefore furnishes a more comprehensive index of the true quality of the milk.Potentiometric studies with a wide variety of milks have failed to support the view that resazurin exerts such a strong poising action in market milks as to complicate the test or interfere with the interpretation of results. No evidence was obtained in support of the claim that differences in poising properties of different milks are of sufficient magnitude to affect the results of the test.

Although the volume of ingredients in ewe’s milk is substantially higher than in cow’s milk, its hygienic quality is lower. The weak quality of raw ewe’s milk limits the possibilities of processing and results in bad quality products. In our investigation we analysed the state of ewe’s milk processing at a typical medium size dairy firm. We investigated the collection, the amount and the quality of milk and the level of ingredients in milk throughout the purchasing period (lactation period).The purchasing of ewe’s milk was limited to 5 months (from April to September). Although meat (lamb) provides the major source of income to sheep breeders the extension of the period of ewe’s milk production can be beneficial to shepherds and dairy firms. The amount of ewe’s milk ingredients found corresponded to published findings. However, the hygienic quality of ewe’s milk was varied greatly in the different milk samples and these deviations meant bad quality on average. Physiological factors, the circumstances of sheep breeding and milking, the slow cooling of the milk, the little amount of daily milk and the long storage before transportation to the dairy firm together cause poor hygienic quality. The main problem is the long storage time of milk, but our results raise the question of reconsidering the quality classes. Investigating the effect of the hygienic quality of raw milk on product quality, we can get correct data that can be really authoritative.

AbstractThe aim of the research was to assess the quality of milk from mountain sheep used for the production of traditional cheeses, taking into account the influence of the breed, the month of milking, and the content of somatic cells. Milk for the study was obtained from sheep of three mountain breeds: Podhale Zackel (PZ), Polish Mountain Sheep (PMS), and Coloured Mountain Sheep (CMS). The sheep were grazed in mountain pastures after lamb weaning, in the period from May to October in the traditional system. No influence of the breed on the examined parameters was found, except for urea content. Mountain sheep milk was characterized by a content of 19.68% solids, 8.48% fat, 6.63% protein, in which almost 76% was formed by casein (4.99%), and the average lactose content was 4.15%. Other milk parameters also did not differ between breeds: density was 1034.04 g/L, acidity 11.34°SH, and mean somatic cell content was 982.13∙103∙ml−1 (log10SCC = 5.68). The highest urea content was recorded in the milk of Coloured Mountain Sheep (280.69 mg/L) and the lowest urea content was recorded in the milk of Zackel sheep (200.97 mg/L). The month of milking influenced the content of most milk components, but no changes in SCC content during lactation were found. Significant correlations between fat content and other milk parameters were recorded. In the case of urea content, negative, statistically significant correlations with the majority of examined parameters were found.

Abstract. The aim of this study is to study the effectiveness of the use of various means for treating the udder of cows in order to prevent the incidence of mastitis and improve the quality of milk. Since in order to prevent the development of mastitis for a long time, it is necessary not only to destroy the disease itself and fight its symptoms, but also to take all kinds of measures to prevent the disease. Methods. To conduct a scientific and economic experiment, 4 groups were formed, of which 3 are experimental and 1 control, according to the method of pairs-analogs using a tethered method of keeping in stalls in all four groups. To treat the udder, agents based on iodine, chlorhexidine, chlorhexidine digluconate and probiotic bacteria were used. Results. The summer use of Priolit Vortex and Algavit Vortex in 1 experimental group showed a decrease in the number of mesophilic aerobic facultative anaerobic microorganisms in cow's milk from 200,000 to 97,000 CFU/cm3, which is 48.5 % less than at the beginning of the experiment. Treatment with disinfectants Priolit Vortex and Elovit Vortex in the 2 nd experimental group made it possible to reduce the number of mesophilic aerobic facultative anaerobic microorganisms by 68.4 %. The use of probiotic agents Skin Cleaner and PIP Cow Teat Cleaner for treating the udder of cows allowed to reduce the number of mesophilic aerobic facultative anaerobic microorganisms in the milk of cows in experimental group 3 from 180,000 to 110,000 CFU / in 1 cm3, which is 61.1 % less than the initial indicators. Somatic cells in the milk of cows of the 1st experimental group decreased from 750,000 to 120,000 in 1 cm3, in the 2nd experimental group the number of somatic cells decreased from 250,000 to 180,000 in 1 cm3, in the 3rd experimental group from 390,000 to 340,000 in 1 cm3. In the control group, an increase in the number of somatic cells was found by 84 %.
