The experiment was performed on 60 male French Lop rabbits reared under extensive conditions and sacrificed at body weights of approximately 3 kg at the age of 150 d (30 animals) and approximately 4.5 kg at the age of 210 d (30 animals). Chilled carcasses without heads were divided into the front, middle and hind sections, which were then dissected to separate lean meat (including intramuscular fat), fat and bones. An increase in the body weight of rabbits at slaughter was accompanied by a decrease, of about 0.60%, in the proportion of the head and giblets (kidneys, liver, heart and lungs) in the carcass, and by an increase in the perirenal fat content from 0.66 to 1.69%. The average carcass dressing percentage of rabbits sacrificed at an average body weight of 3054 g reached 49.13%, and it was 2.49% higher than in rabbits slaughtered at a body weight of 4427 g. The percentage content of the front, middle and hind sections of the carcasses of the lighter rabbits was 38.50, 21.76 and 39.74%, respectively. In the carcasses of the heavier rabbits, the proportion of the front section was 2.29% higher, the proportion the hind section was 2.45% lower, while the proportion of the middle section remained at a similar level as in the lighter rabbits. The carcasses of the lighter rabbits, compared with the carcasses of the heavier rabbits, had a higher percentage content of meat (82.60 vs. 81.15%; P ≤ 0.01) and a lower percentage content of fat (1.78 vs. 4.38%). In addition, rabbits sacrificed at a body weight of approximately 3.0 kg were marked by a higher content of lean meat in the middle and front sections of the carcass (by 1.89 and 3.07%, respectively), and by a slightly lower content of lean meat in the hind section (by 0.85%).

Oxygen uptake (VO2) through the gills of a hill-stream fish Glyptothorax telchitta from the Saptakoshi river (Nepal) has been studied in relation to different body weights. The oxygen uptake was determined at 24.0±1°C using a cylindrical glass respirometer with continuous water flow system. The aquatic oxygen uptake through the gills increased from 1.048 to 8.115 mlO2 kg-1.h-1 within the body weight range of 3.215 to 31.355 g. A fish of 17.052 g average body weight consumes 4.461 mlO2-1.h-1. The relation between oxygen uptake (VO2) and body weight was determined by performing regression analysis using logarithmic transformation. It has been found that with a unit increase in body weight, the oxygen uptake per unit time (mlO2h-1) increases by a power of 0.930 showing significant positive correlation whereas, the weight specific oxygen uptake decreases by a power of 0.070 showing significant but negative correlation.

Research was carried out in population of R2 generation Pirot pramenka x Pirot improved sheep during period of three years. Lambs were divided into three groups: I from 2.5 kg to 3.5 kg; II from 3.6 kg to 4.5 kg; III from 4.6 kg to 5.5 kg. Weight of lambs was controlled at birth, with 30, 60 and 90 days of age. Average body weight at birth of the tested lambs was 3.35 kg in the first group, 4.30 kg in the second group and 5.06 kg in the third group. At 30 days of age, the body weight of the lambs was 10.19 kg in the first group, 11.39 kg in the second and 12.49 kg in the third group. All these differences in body weight of lambs at birth were statistically highly significant (P_ 0.01). With 60 days of age, average body weight was 16.48 kg in the first group, 19.01 kg in the second and 20.49 kg in the third group. Differences between groups of lambs at this age were statistically very significant (P_0.01).On the end of experiment at 90 days of lambs age, we have found the following values of the body weight of lambs: 26.35 kg in the first group, when the second 30.49 kg and 28.93 kg in the third group. Differences between groups of lambs at this age were statistically very significant (P_0.01). At the age of 90 days maximum weight of the body was in the second group of lambs, or a group which body weight at birth occupied the mean of the population. Correlations between body weights of lambs vary from weak to midsized values. The highest values of correlation coefficients were found between body weight at birth and weight of lambs at 30 days of age.

Abstract Local chickens in developing countries, including Indonesia, have great potential to be developed into natural superior breeds to support food security and improve farmer welfare. Meanwhile, the major endemic subspecies found in the Bengkulu province are burgo and kampung chicken, as well as ketarras which are recently bred intensively. Therefore, this study aims to analyze the disparities in the morphometrics of three subspecies of local male chickens specifically on the body weight, length, chest girth and length, as well as wing span. Based on the results, the male burgo chicken morphometrical size was significantly smaller than ketarras, while the ketarras chicken was significantly smaller than kampung (P < 0.05). Furthermore, the average body weights for the burgo, ketarras and kampung chicken were 1.0, 1.2 and 1.9 kg cock-1, respectively, while the average of body length, chest and chest length, as well as wing span were 29.9, 40.0, 47.7 cm cock-1; 26.2, 30.1, 36.3 cm cock-1; 12.6, 17.8, 20.3 cm cock-1, and 34.4, 41.9, 55.9 cm cock-1, respectively. Therefore, it was concluded that the burgo and kampung chicken have the smallest and biggest morphometric sizes respectively.

The objective: to develop a regional gestational percentiles table of body weight for newborns in Kiev and Kyiv’s oblast. Materials and methods. Data of the body weight of newborns were collected from Kyiv City Perinatal Center from January 2016 by January 2017. The total number included 5244 live births in the period of gestation 40+0–40+6 weeks of gestation. The standard deviation of the body weight, expressed as the percentage of the average body weight of all newborns, as well as the percentil calculator developed by Hadlock et al, supported by the WHO (2008), was used to generate the percentages and curves of the body weight. Materials and methods. A newborn body weight percentile table was constructed, depending on the gestational age. Differences were observed between the current average body weight of newborns for Kyiv and current WHO links. Conclusion. We found a rise in the average body weight of newborns, which we associate with excessive, unbalanced diet and the prescribing of a complex of multivitamins and biologically active substances during pregnancy. This indicates the importance of using this table for differential diagnosis of normal fetal growth from intrauterine growth restriction and small for fetal gestational age within the region of Kyiv and oblast. Key words: delayed fetal growth, percentile table of the city of Kiev, average body weight of newborns, percentile schedule.

The results of reproduction were tested in females of the African catfish (Clarias gariepinus Burchell 1822) after stimulation of ovulation with carp pituitary (4 mg/kg body weight) or with Lecirelin (15 &mu;g/kg) and metoclopramide (10 mg/kg). After administering the synthetic substance eggs were obtained from all females while in the group treated with pituitary homogenate 7 out of 8 hypophysed females spawned. The applied spawning agent did not significantly influence the weight of eggs expressed in grams, but in the case of females treated with carp pituitary homogenate a significantly higher weight of eggs expressed as the percentage of body weight of fish was recorded. The applied stimulators of ovulation did not affect any trait reflecting the quality of eggs. Females used as an experimental material belonged to two categories in respect of body weight: lighter females with average body weight of 2.63 &plusmn; 0.36 kg and heavier females with average body weight of 3.91 &plusmn; 0.48 kg. It was proved that the weight of eggs expressed either in grams or as a percentage of a female&rsquo;s weight was significantly related to the body weight of a female (P &le; 0.01 and P &le; 0.05, respectively), as well as the percentage of fertilised eggs and the percentage of living embryos after 28 hours of incubation (P &le; 0.05 and P &le; 0.05, respectively). The interaction between the stimulator of ovulation and the female body weight was significant only for traits reflecting the weight of obtained eggs (P &le; 0.05 and P &le; 0.01). &nbsp;

Benzo(a)pyrene (BaP) is one of several examples of polycyclic aromatic hydrocarbons that come from incomplete combustion of organic materials.BaP compound is used in research to induce fibrosarcoma.In general, patients with cancer will experience a reduction in body weight. This study aims to determine the body weight profile, the time it takes to cause fibrosarcoma, and the mortality rate of male Sprague Dawley rats after injection with BaP. In this study, 18 rats were used with two treatments.Rats in treatment 0 (P0) were not treated, while rats in treatment I (PI) were injected with BaP 0.3% in 0.1 mL oleum olivarumten times given gradually at two-day intervals via subcutaneous. There were six and 12 rats, respectively, P0 and PI. BaP solution is prepared by dissolving in oleum olivarum, mixing, and stirring until homogeneous. The rats were weighed at the beginning of the study and then carried out routinely once a weekfor 19 weeks of research. At the beginning of the study, the average body weight of rats at P0 and PI were 121.43 ± 7.04 g and 131.49 ± 16.31 g, respectively. The mean body weight of the rats at P0 and PI from the first week to the 19th were178.53 ± 29.97 g and 159.20 ± 14.24 g, respectively. The time taken to inducefibrosarcoma was 85.5 ± 17.6 days. The mortality rate in treatment P0 was 0% and PI treatment was 8.33%.From the results of this study, it can be concluded that giving BaP significantly reduces the body weight profile of rats and has a mortality rate of 8.33%.

The body weight of calves in the earliest period of their life (age from 0 to 7 days) is under the greatest influence of the farm and the season of birth. The farm manifests its influence most often through the conditions of nutrition and housing and the organization of the technological production process, while the influence of the birth season is manifested through microclimatic and nutritional conditions, as well. The most common deficiencies related to the nutrition of newborn calves are related to: inadequate colostrum supply in terms of quality, quantity and time of colostrum intake, which is closely related to the organization of the technological production process on the farm. Dietary deficiencies affect the body weight of calves at birth and at 8 days of age. In a study conducted over a year (4 seasons), the colostrum diet of newborn calves of the HF breed on two farms (A and B) with a tied housing system was analyzed. Calves were fed colostrum on both farms at intervals, usually up to 2 hours, less often up to 4 hours after birth. The colostrum consumed came from the mother, most often, and less often from the other cow, while on one of the farms it was also used frozen. However, the amount of colostrum consumed was deficient, it was 1-2 l on farm A, and 2.5 to 3 l on farm B. The occurence of a deficient diet or other deficiencies in the diet of calves was indicated by the average body weight, measured at birth and at the age of 8 days. On farm A, a lower average body weight of calves (37.95 and 39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories, respectively. The average body weight of calves was statistically significantly (p <0.01) influenced by the farm and the season of birth, as well as their mutual interaction, but the effect of the farm was more pronounced.

Obesity is a health problem in the community because it can cause a risk of degenerative diseases such as type 2 diabetes mellitus, high blood pressure, heart disease, cancer, and atherosclerosis. Unhealthy lifestyles such as lack of physical activity by exercising, a diet high in carbohydrates and fats, can cause fat deposits in the body, especially in the abdomen. The use of chemical drugs such as Orlistat as a weight loss or to help reduce the risk of regaining lost weight, is less effective because it requires a long consumption time and the presence of side effects. Tin leaf content (Ficus carica Linn) is flavonoids, alkaloids, tannins and steroids, tin leaf extract has IC50 150mg/L antioxidant activity. This study was to determine the anti-obesity activity of tin leaf extract in male Sprague-Dawley rats given a high fat diet. 30 Sprague-Dawley rats were classified into 6 groups. The results obtained, in the group dose of 100 mg / kg obtained an average body weight of 381.8 grams, the test group 200 mg / kg obtained an average body weight of 414.5 grams, in the test group 400 mg / kg obtained 387 grams. The conclusion of this study is that the activity of Tin leaf extract (Ficus carica Linn) can be used as an anti-obesity.

Abstract. A total of 238 Pannon White growing rabbits were slaughtered at 74, 84 and 94 days of age, at an average body weight of 2.53, 2.84 and 3.15 kg, respectively. Within each age group five body weight categories were formed in such a way that the weight difference between two neighbouring groups was equally 0.3 kg. The design of the experiment permitted the separate examination of the effects exerted by age and body weight on carcass traits and on meat chemical composition of the left hind leg (HL) and that of m. Longissimus dorsi (MLD). Dressing out percentage significantly increased with the increase of age in all body weight categories, as well as with the increase of body weight. The effect of age on the ratio of the fore part of the carcass depended on the body weight: significant difference was found in lower body weight categories. The ratio of the intermediate part of the carcass was not affected by age but it increased in rabbits of higher body weight. The ratio of the hind part of the carcass increased in older animals, while it decreased in rabbits of higher body weight, and this decrease was higher in older rabbits. The ratio of the perirenal fat to reference carcass significantly decreased with age in all body weight categories, but it significantly increased in rabbits of higher body weight. With the advancement of age the moisture content of the HL increased, while that of the MLD did not change. With the increase of body weight, moisture content decreased in both the HL and in the MLD. The fat content of both HL and MLD decreased in older animals, while it increased in rabbits of higher body weight.

OBJECTIVES/SPECIFIC AIMS: It has been reported that birth mode affects development, with cesarean section born mice gaining more body weight during development. Since mice C-sections involve fostering and nest change, we sought to determine whether changing only the nest and cage would have an effect on development. METHODS/STUDY POPULATION: A total of 53 mice were born to 9 dams, and 21 babies (4 litters) were exchanged in pairs to foreign cages and nests. Litters were followed for body weight and mothers were observed during periods for maternal and nonmaternal behaviors. RESULTS/ANTICIPATED RESULTS: The results show that average body weight was significantly higher in the experimental group in both genders, with 20% higher body weights at weaning. The mothers from the litters that were changed to a new nest showed significantly more non-maternal behavior in the first 2 days if life, than the controls. DISCUSSION/SIGNIFICANCE OF IMPACT: The results suggest that changes in maternal behavior may be linked to the increased weight gain in their babies.
