Abstract The paper presents the results of the scientific and economic experiment for the evaluation of the influence of the energy supplement included in the diet of lactating cows of the Brown Swiss breed. During the research period, all animals were kept in the same conditions, corresponding to zootechnical standards. They were divided into two groups differentiated only by the feed ration. The cows of the first (control) group were given rations typical for the farm corresponding to the feeding norms of dry and lactating cows. For the cows of the second group in the dry period (14 days before calving) the feeding ration was changed with a change in structure towards an increase in the proportion of concentrated feed, and immediately after calving, they received an energy feed supplement to maintain the physiological status of dairy cows after calving. Only clinically healthy animals participated in the experiment. It was revealed that the inclusion of the energy feed supplement in the diet of lactating cows in the experimental groups during lactation led to an increase in the productivity of livestock as compared with those in the control group.

Hand-fingerprint analysis is one of the biometric methods for knowing a person's character. Fingerprint analysis was developed as one of the methods to find out the most dominant brain functions affecting one's genetic potential. Through the interpretation of fingerprint patterns and measurements of the lines at the end of each finger can be read potential, motivation, learning style, work style, even the potential stress of a person who was born from birth. The existence of the relationship between the pattern of fingerprint with the character of a person raises the idea to create a system that can be used to analyze the characteristics of a child based on the type of fingerprint pattern it has. The system can perform analysis based on the fingerprint and hand angle patterns to get the type of spelling, learning style and character in the child in order to facilitate user in analyzing automatically based on fingerprint pattern and hand corner of input to get the output type of spiritedness, learning style and character in child.

Objective. To analyze the peculiarities of eating behavior and diet of medical students, to reveal the relationship between dietary habits and gastrointestinal symptoms. Materials and methods. A one-step anonymous survey of 996 students of 1-6 grades of the Chita State Medical Academy was carried out. The author’s questionnaire contained 53 questions concerning the peculiarities of the diet, the quality of the consumed products, as well as aimed at identifying gastrointestinal symptoms and hereditary factors in students. Statistical processing was carried out using the Statistica 10.0 program, correlation analysis was carried out using gamma correlation. Results. Only 40% of the respondents eat regularly at least 3 times a day. Almost 80% of students periodically skip meals at lunchtime, replacing it with a “snack on the run”: 45% 1-2 times a week, 24.8% 3-4 times a week, 9.4% daily during the school week. A positive correlation was found between the frequency of “snacking while running” per week with the frequency of pain (p = 0.0000001) and symptoms of gastric dyspepsia (p = 0.0000001). Only 57% of the respondents have breakfast. Abdominal pain 1-2 times a month and less was in 37.6% of respondents, 1-2 times a week - 26%, 3-4 times a week and more often - 7.4% and only 22% did not complain of pain in a stomach. Conclusion. Most of students have eating disorders that include inadequate breakfast, snack instead of lunch, lunch-dinner, and eating after 22:00. The relationship between the frequencies of eating disorders, fast food consumption, chips with gastrointestinal symptoms was revealed.

Abstract Sow functional teat number (FTEAT) is positively associated with piglet preweaning survival and litter throughput. The objective was to estimate the value of FTEAT in relationship to litter size to optimize the number of pigs weaned. Number of pigs born alive (NBA) and total teat number (TTEAT) were counted at farrowing on 836 multiparous purebred sows between March and September, 2020. Teats were evaluated by trained staff at farrowing and considered functional based on visual appraisal of teat morphology. Litter size at weaning (LSW) was recorded after a 26.5 d lactation length (LL). Sow was the experimental unit and all data were analyzed as a function of the biological sow. Number born alive was categorized by quartile: Q1 ≤ 10 NBA (n=185; µ=8.2); Q2 = 11 to 12 NBA (n=194; µ=11.6); Q3 = 13 to 14 NBA (n=238; µ=13.5); Q4 ≥ 15 NBA (n=219; µ=16.3). Data were analyzed in PROC GLM of SAS with farm, breed, and NBA quartile as categorical effects and LL and FTEAT as linear terms. The interaction of NBA quartile and FTEAT was also included. Mean TTEAT, FTEAT, LSW and preweaning survival were 15.4, 14.5, 11.3 and 89.4%, respectively. As a linear term, a one teat increase in FTEAT improved (P< 0.01) LSW by 0.3±0.1 pigs. Yet the value of an additional functional teat increased with increasing NBA. A one teat increase in FTEAT improved (P< 0.01) LSW in Q1, Q2, Q3, and Q4 by 0.12, 0.27, 0.33, and 0.38 pigs, respectively. The analysis demonstrates the impact of FTEAT on sow performance increases with increasing litter size, and highlights the importance of functional teats to optimize litter throughput and maximize the genetic potential of a maternal line.

The Relationship

The daily rate of lean deposition achieved by growing pigs is a function of a wide range of factors including genotype, gender, liveweight and intake of energy/protein. The review of ARC (1981) highlighted the controversy surrounding the effects of liveweight and energy intake on lean deposition. Recent publications suggest that there are interactions between these factors and also with genotype. In contrast to the linear/plateau relationship between energy intake and protein deposition proposed by Whittemore and Fawcett (1976), Campbell and Taverner (1988) observed a linear response in protein deposition up to the highest energy intake achieved, with pigs of improved genotype. The slope of the relationship was much greater than that observed in previous studies (ARC 1981). In a recent experiment, McCracken and Rao (1989) have shown that high-lean pedigree boars can achieve protein deposition rates as high as 200 g/d over the liveweight range of 33 to 88 kg. At present there is no published information on the response of such pigs to energy intake though the low rates of fat deposition observed suggest that energy intake could be limiting protein deposition. The experiment described below was designed to measure the response of protein deposition to energy intake at a series of liveweights between 33 and 88 kg. The diet and the treatments were chosen to obtain a wide range of energy intakes above and below those observed with dry, pelleted diets.

The Relationship

The objective of the current study was to evaluate the relationship between the serum macromineral, metabolite profiles, and the clinical endometritis during the transition period in Brown Swiss dairy cows. Sixty Brown Swiss dairy cows were used in the present study. Blood samples collected at d 10 (± 4) antepartum and 3, 10 and 30 (± 4) days in milk (DIM) to determine calcium (Ca), phosphorus, glucose, cholesterol, non-esterified fatty acid (NEFA) levels. Beta-hydroxybutyric acid (BHB) concentration measured during the postpartum period. Receiver operating characteristics (ROC) curves were used to determine the cow-level thresholds for the subsequent development of clinical endometritis. In addition, pairwise comparisons were made of the area under the curve (AUC) of ROC curves for the thresholds of NEFA, Ca, and glucose predicting clinical endometritis. The mean Ca concentration at 3 DIM was 8.85 ± 0.20 mg/dL in healthy cows compared to 8.30 ± 0.22 mg/dL in cows that subsequently developed endometritis (P < 0.05). NEFA concentrations at 10 DIM and BHB concentration at 10 and 30 ± 4 DIM were higher (P < 0.05) in cows that subsequently developed endometritis. Serum NEFA concentration at 10 days postpartum is the best predictor for diagnosis of clinical endometritis with the AUC values of 0.741. The cows with clinical endometritis also had significantly higher values of glucose at 3 DIM and lower BCS at 10 DIM (P < 0.05). While 58.6% of the cows that developed clinical endometritis were cyclic, 64.5% were cyclic in healthy cows at 30 ± 4 DIM. Serum NEFA concentration was the only risk factor for clinical endometritis at 10 DIM. In addition, a decrease in serum Ca at 3 DIM and increase in NEFA and BHB concentrations at 10 and 30 ± 4 DIM may be associated with clinical endometritis and delayed resumption activity on the ovaries.

The Relationship

Up to this point, the scientific basis for caries control and practical details for delivery of caries control to the individual have been given. We now change tack and consider caries control in populations. In order to follow the health profiles in populations there is an important tool called epidemiology. This literally means ‘the study of what is upon people’. It is derived from Greek where ‘epi’ means upon or among and ‘demos’ is people (population). In other words, epidemiology is the study of the distribution (how often) various diseases occur and why they appear in well-defined populations. It deals with groups of people, not individuals. Data thus obtained are used in public health for developing and monitoring strategies for health care in populations. Moreover, it can tell how diseases are influenced by hereditary factors, by physical and social environments, and human behaviour. All this helps health authorities to develop appropriate preventive interventions and make these as cost-effective as possible. In this chapter, having introduced the concepts of epidemiology, examples of caries control in two populations and its assessment using epidemiological measurements is given. However, the use of epidemiology has already been described in Chapter 4, where Dean’s observations on the relationship between fluoride in water supplies, the resulting dental fluorosis, and the concomitant caries reduction are described (see Chapter 4). In a recording system of any disease it is important to have clear criteria for diagnosis. The following are important: ◆ How valid are the criteria of measurement? Do they record what they are intended to measure? ◆ How reliable are the criteria? Reliability is also covered by the terms reproducibility, and consistency. These terms imply that the same or different examiners can use the criteria in the same way on different occasions and obtain the same result. ◆ The criteria should be clear, simple, and objective. In other words robust. This is particularly important if manifestations of a disease are to be grouped in different categories of severity, as with dental caries.

The article reflects the current state and the prospects of the Kostroma cattle breed development. The creation and improvement of the breed anticipated the formation and further breed development in the domestic and world zoo technical science. In recent years, the number of Kostroma cattle breed has been unreasonably reducing despite its economic valuable traits. At the same time in the Kostroma region there are prospects for preserving the valuable gene pool of one of the best domestic dairy and meat cattle breeds. As a result of directed selection and breeding work with the use of Brown Swiss bulls, a stud milk breed "Karavaevsky KK-1" has been developed. At present cow-champions of the Kostroma breed give up to 12,000 kg of milk per lactation. The milk of the Kostroma breed cows has a high content of protein and fat. The animals of Kostroma breed have good meat qualities, high resistance to a number of diseases, strong ungulate horn, easy adaptability to intensive technologies, good fertility and high productive longevity. To save the Kostroma breed it is important to put on 8-10 bulls of 8 planned lines and related groups for the validation and accumulation of sperm every year. The restoration of previously created lines with high genetic potential should be foreseen. It is necessary to identify and actively use the stud bulls bred in their own breeding farms; to conduct a linear assessment of bulls and daughter heifers by body type for more competent selection. In addition to the generally accepted forms and methods of selection, it is necessary to continue immunogenetic control of the authenticity of the origin of breeding animals and introduce modern methods of DNA technology to assess the breeding and productive qualities of cattle, which will reveal valuable genetic complexes in the best breeding animals and thus 1.5-2 times accelerate the selection processes.Conflict of interest: the authors stated that there was no conflict of interest.

The aim of the present research was to determine the relationship between somatic cell count (SCC) and milk composition. Milk samples were collected in November and May in 2012. In the study, 128 milk samples from Brown Swiss cattle, divided into two groups. They were arranged from low score (≤500 000cell/ml) to high score (>500 000cell/ml) according to the Turkish Food Codex upper limit. The averages of SCC were determined as 10.444±0.073cells/ml for first group and 10.820±0.088cells/ml for second group, respectively. In the one group dry matter, non fat dry matter, fat, protein, lactose levels and standard errors were determined as 13.3±0.60%, 8.3±0.21%, 4.5±0.61%, 3.0±0.14% and 4.7±0.07%, respectively. The other group same traits were calculated 13.7±0.17%, 7.9±0.10%, 5.8±0.14%, 3.0±0.06% and 4.1±0.05%, respectively. Significant correlations were found between SCC and non fat dry matter (r=-0.109) protein (r=0.145), lactose (r=-0.490) in the second group. But, non significant correlations were determined between SCC and dry matter, non fat dry matter, fat, protein and lactose in the first group. As a result, increasing of the number of somatic cells, milk, lactose, protein, and fat-free dry matter content was determined to be significantly affected.
