The Relationship

AbstractThe relationship between puberty and the cessation of luteal activity after nutritional restriction was evaluated in 15 Angus × Hereford heifers. Heifers attained puberty at a body weight of 297 (s.e. 6) kg and a body condition score (BCS) of 5·5 (s.e. 0·1) on a scale of 1 (emaciated) to 9 (obese). After 154 (s.e. 16) days of nutritional restriction, heifers became anoestrus at a weight of 273 (s.e. 8) kg and a BCS of 3·0 (s.e. 0·2). The Spearman's rank correlation coefficient between date of-puberty and date of cessation of luteal activity was (r = –0·49; P < 0·06). This indicates that the heifers that attained puberty first were the last to cease luteal activity during nutritional restriction.

Purpose: to determine the relationship between the performance of basic elements and indicators of static and dynamic balance in the training process of young acrobats 6-7 years. Material and methods. The study involved 16 young acrobats at the stage of initial training (age 6-7 years). All parents of the participants gave written consent for the participation of children in the study. The study involved testing the technique of performing basic elements of sports acrobatics and assessing the static and dynamic balance of young athletes. The relationship between (swallow, shoulder blade, forward squat, wheel (sideways overturning), bridges) and static and dynamic equilibrium tests was determined. Spearman's rank correlation coefficient method was used as a method of statistical analysis. Results. It is established that the largest relationship between the performance of basic elements and static balance in the basic exercises of young acrobats have: Romberg's test with the elements "Swallow", "Stand on the shoulders", "Bridge"; Biryuk test with elements "Swallow", "Wheel", "Bridge"; balance "Swallow" with elements "Swallow", "Wheel"; static equilibrium test with the elements "Swallow", "Rack on the shoulders", "Rolling forward with a squat", "Wheel". Reliable values ​​of the correlation coefficient were established between the tests of dynamic balance and the basic elements of sports acrobatics in young athletes 6-7 years, namely: "Swallow", "Flip forward with a squat", "Wheel" and "Bridge". The analysis of special tests of static and dynamic balance in mastering the basic elements of acrobatics at the first stage of long-term training makes it possible to use them to determine the level of coordination capabilities of young athletes and further improve the use of acrobatic exercises. Conclusions. A reliable relationship between the performance of basic exercises and indicators of static and dynamic balance in young acrobats at the initial stage of training. It is shown that the level of static and dynamic balance is of great importance for the assimilation and improvement of basic elements of technology by young acrobats 6-7 years. Static and dynamic balance tests can be used to individually build training programs and young acrobats. It is shown that sports acrobatics is a significant means of developing the balance of children 6-7 years.

ABSTRACTAn analysis of the records of ewe weight and condition at mating together with subsequent lambing performance for several commercial flocks in the UK revealed no significant relationship between lambing performance and size, measured by weight transformed to a standard condition. The relationship between mating weight and body condition score at mating was linear though there was considerable variation in weight at a fixed body condition, suggesting a substantial spread in skeletal size. Increases in ovulation rate were not discernible from lambing figures over the range of body conditions observed in these flocks.

Introduction. One of the most significant components of acute destructive pancreatitis (ADP) is enzymatic parapancreatitis (EP). The severity of the defeat of the retroperitoneal tissue from the early stages of the disease largely determines its course.The objectivewas to assess the features of the evolution of the pathological process in the retroperitoneal tissue in ADP and the effect of EP on the course of phase I of ADP.Methods and materials. 63 cases (ADP) without enzymatic peritonitis were analyzed. The average age of patients was (46.6±3.2) years (p≤0.05). The sum of points according to the express diagnostic scale of the SPb I. I. Dzhanelidze RIEM was (3.7±0.2) points (p≤0.05). The average time from the onset of the disease to the start of therapy was 2 days (from 7 to 1 day).Results. Types of EP at admission were distributed as follows: type B – 17.5 % (n=11) of cases, type C – 44.4 % (n=28) of cases, type D – 30.2 % (n=19) of cases, type E – 7.9 % (n=5) of cases. Spearman’s rank correlation coefficient for assessing the relationship between the severity of the condition and the type of parapancreatitis was 0.069. Infiltrative parapancreatitis (IP) was formed in 93.4 % of cases. The types of infiltrative parapancreatitis (pancreatic infiltrate) were distributed as follows: type A – 12.3 % (n=7) of cases, type B – 21.1 % (n=12) of cases, type C – 36.8 % (n=21) of cases, type D – 19.3 % (n=11) of cases, type E – 10.5 % (n=6) of cases. There was a pronounced relation between the severity of the patient’s condition and the prevalence of IP, the Spearman’s rank correlation coefficient was 0.82.Conclusions. EP is formed in most cases of acute destructive pancreatitis and is evolutionary. It has a significant effect on the severity of the patient’s condition and the course of acute destructive pancreatitis in the infiltrative phase of the disease.

Technology transfer to farmers is essential for the improvement of agricultural production in a country like Bangladesh. In connection this issue, the study was conducted to assess the extent of problems faced by Sub Assistant Agricultural Officers (SAAOs) in technology transfer as well as explore the relationship between the selected characteristics of Sub Assistant Agricultural Officers and problems faced by them in technology transfer. The study was conducted in five sub-districts of Narayanganj district namely, Narayanganj sadar, Bandar, Sonargaon, Araihazar and Rupganj with a sample size of 129 by questionnaire method through a structured questionnaire. Spearman’s Rank Correlation Coefficient was used to test the relationship between the selected eight characteristics of SAAOs and the problems faced in technology transfer. The findings reveal that 70.50% of the SAAOs encounter high problems while 27.90% and 1.60% respondents were in medium and low problem category respectively. Spearman’s Rank Correlation Coefficient analysis also revealed that training exposure, job satisfaction and use of the internet showed a negative significant relationship with the problems faced in technology transfer. Based on Problem Faced Index (PFI), “lack of required teaching aid” ranked the highest problem followed by “lack of transportation facilities”.

The Relationship

This study examined the relationship of body condition and chewing time (CT) with body weight (BW), the level of cocaine-and amphetamine-regulated transcript (CART), leptin and energy metabolites in cows until reaching the lactation peak. The results showed the greatest loss of BW between days 11 and 45 of lactation and a decrease in the body condition score (BCS) until day 75. Chewing time showed an increase from day 45 with the highest values after lactation peak. The CART and leptin concentrations demonstrate a reduction of both indices (P < 0.05) between days 11 and 75. The function of leptin as a factor positively correlating with BW and BCS was found. In the heaviest individuals and those with higher BCS, the blood leptin levels were higher. The results of beta-hydroxybutyrate (BHBA) indicate that cows with the lowest BCS had the most intensive energy transformation. This led to a higher BHBA concentration compared to the cows with high BCS (P < 0.05). The obtained results show that CART was most strongly negatively associated with CT (P < 0.05). For leptin, the tendency was the opposite and the correlation with CT was not significant. The results suggest that CT may be stronger regulated by CART, which has anorectic properties, than by appetite inhibiting leptin. Significant decrease of body condition during lactation is a great problem for dairy farmers. The explanation of the issue of the participation of CART and leptin in the regulation of body’s energy homeostasis may therefore be of importance for milk production.

AbstractThe relationships between body weight (BW), body condition score (BCS) and internal fat deposits were studied in Latxa dairy ewes. In 2 years, the BW and BCS of 20% of the ewes in 14 flocks were recorded at the beginning of the mating period (pre-mating), and in the 1st month of lactation (post lambing). BW increased with age (BW = 54·05 × (1-e−0·988 × age), and the mature weight was not reached until 4 years, after which weight did not differ between pre-mating and post-lambing periods. Body condition score, however, differed between the two periods. The regression coefficients (b) of BW on BCS, when flock-year and age were included in the regressions, differed significantly (P < 0·05) in the pre-mating and post-lambing periods, and were 5·3 (s.e. 0·31) and 6·3 (s.e. 0·43) kg per unit BCS, respectively. The correlation coefficients (r) were 0·77 and 0·71 respectively, compared with 0·42 and 0·38 when the flock-year and age of the ewes were not included in the regression.Thirty-seven of these ewes, with BCS between 0·75 and 4·00, were slaughtered, the weights of omental, mesenteric and kidney and channel fat recorded, and the lumbar fat thickness assessed at the last rib. The regressions between the weight of fat deposits and lumbar fat thickness and BW and BCS fitted to semi-logarithmic equations, except for mesenteric fat, in which the relationship was linear. Body condition score was a better predictor than BW for individual fat deposits, with proportionately 0·81 to 0·83 of the variation in the weight of the deposits accounted for by variation in BCS and 0·57 to 070 by variation in BW.

The objectives of this study were to detect the relationship between body mass index (BMI) and body condition score (BCS) in Pelibuey ewes to predict BMI based on well-known BCS estimation. The body weight (BW), withers height, (WH), body length (BL) and BCS were determined in 402 ewes. The BMI was calculated as: BMI = (BW (kg)/WH (m)/ BL (m))/10. Relationships were estimated by means of regression models using PROC REG of the SAS. The BMI and the BCS showed a high relationship; correlation coefficient (r) of 0.80 (P<0.001). The linear regression for BMI prediction was as followed: BMI (kg/m2) = 8.38 (±0.189***) + 1.70 (±0.064***) × BCS (R2 = 0.65, MSE: 2.56; RMSE: 1.60; P <.0001 and n = 402). The BMI could be used as an indicator of the degree of obesity in non-pregnant and non-lactating Pelibuey ewes under field conditions.

Abstract This research communication describes the relationship between the occurrence of lameness and body condition score (BCS) in a sample of 288 cows from a single farm that were repeatedly scored in the course of 9 months while controlling for confounding variables. The relationship between BCS and lameness was evaluated using generalised linear mixed-effects models. It was found that the proportion of lame cows was higher with decreasing but also with increasing BCS, increased with lactation number and decreased with time since the last claw trimming. This is likely to reflect the importance of sufficient body condition in the prevention of lameness but also raises the question of the impact of overcondition on lameness and the influence of claw trimming events on the assessment of lameness. A stronger focus on BCS might allow improved management of lameness that is still one of the major problems in housed cows.
