The data on the dynamics of body weight changes, absolute and average daily gains, frequency rate of increase in body weight, relative growth rate and intensity of body weight growth of Limousine and Volyn Meat breeds heifers. Both studied breeds characterized by different body weight at different age periods. Newborn Limousine breed heifers are weighed 2,7 kg more (P < 0.05) than Volyn Meat breed heifers; at 3 months age the difference was 8.5 kg (P < 0.05) at 6 months – 14.6 kg, at 9 month – 20.8 kg (P < 0.05), at 12 months – 25,6 kg (P < 0.05), at 15–months – 31.9 (P<0,05), and at 18 months – 23.5 kg. Total and average daily gains in animals of both breeds were the highest for a period of 3 to 6 months of age. In the period from birth to 15 months of age preference for average daily gains were in Limousine, however, the difference was statistically significant only for the period of 0 – 3 months and amounted to 63,9 g (P < 0,05). From 15 to 18 months of age Limousine slightly conceded to Volyn Meat breeds on this parameter. In animals of both breeds magnification of body weight increased with age, but over the entire period (from birth to 18 months) this parameter in Volyn Meat heifers was 0.6 times better than Limousine heifers. The coefficients of relative intensity and tension increase of body weight in animals of both breeds were highest in the period from birth to 3 months of age. With age, these indicators declined. Mainly, the advantage was in Volyn meat breed heifers, but the difference was not statistically significant.

Abstract. Title of the paper: Milk ingestion and growth performance of suckler calves (cross breeds Galloway x F1 Galloway x Holstein Friesian) from a cow-calf operation. Effects of sex and of life age of calf and of the age of dam On cross breeds (Galloway x F1 Galloway x Holstein Friesian; 12 calves from first pregnancy, 13 calves from second pregnancy; 10 male and 15 female) in a cow-calf operation measurements of body weight were done repeatedly during growth after separating the calves from the dams for 150 min and than again after the calves had contacted the dams for 60 min. Measurements took place always at the same daytime. Milk ingestion of calves was assessed by way of body weight difference method. Acute body weight difference varied markedly between calves and increased with age. The fraction of positive weight difference of all measurements was between 57,1 % and 91,8 % in calves from first pregnancy and between 54,8 % and 90,5 % in calves from second pregnancy the means of which were not significantly different. Mean acute positive body weight changes developed with life age and body growth with different degree in male and female calves. Greatest acute positive body weight changes of calves could be measured at 40 to 70 days of age (70 kg to 100 kg body weight). Growth rate of calves showed greater inter- and intraindividual variation within the first 10 days of life age. Differences in growth rate between male and female calves were more profound in calves from first then in those from second pregnancy.

Data on birth weight and growth rate from birth to 12 months of age of 90 Wadara calves maintained at the University of Maiduguri Livestock Farm from 1980 - 1987 period were studied. Mean birth weight was 25.5±2.6kg; 26.7 ±2.04kg for 40 males and 24.3±3.19kg for 50 females. The linear regression function was fitted on monthly body weight in two parts: 0-6 months and 6-12 months. Maximum gain in body weight was attained during 6 to 12 months of age in the male (8.30±0.50kg) and 0 to 6 months in the female (0.54±1.07kg). The difference in the rate of gain between the periods to 6 and 6 to 12 months in each of the sexes was highly significant (P< 0.01). Body weights at birth and at various ages were higher (P < 0.05) for the male than the female calves. The relative growth rate was rapid in both sexes during the first 3 months and was appreciable to the 7th month of age before declining progressively. The value in the first quarter was 18.0± 1.86 and 20.2 ± 1.60 percent for the male and female calves respectively.

Abstract. The purpose of this study was to establish the growth curves parameters of American Bronze turkeys. The weekly body weight changes of male and female turkeys were recorded during 11 to 24 weeks of age. The Richards' growth model fitted the turkey weight and age (week) data. Profile analysis was also applied to weight-age data in order to get more detailed information about the differences in the live weights of male and female turkeys in consecutive weeks. Estimates for mature body weight were found as 9720.40 ± 971.33 g and higher for males than for females as 6029.96 ± 316.55 g. Based on Richards’ model, male turkeys matured more slowly and it was needed that a more time to reach mature body weight than female turkeys. Results of profile analysis supported those results. Estimates for the absolute growth rate, absolute maturing rate and relative growth rate values were higher for females when compared to males. Male turkeys reached the maximum growth rate at 16.30 weeks of age whereas female ones reached the maximum growth rate at 12.85 weeks of age. Live weights of male and female turkeys, when both reached the maximum growth rate, were 3475.61 g and 2156.06 g, respectively. Male turkeys reached 80 % of their mature weights at 24 weeks of age, whereas female ones reached 92% of their mature weight.

SummaryA survey of sheep production was undertaken in rangeland areas of western Afghanistan to provide basic information of ewe body-weight changes throughout the year and on production variables, including mortality and lambing performance. Ewes lost up to 31% of body weight between December and March and mortality over the same period was 7%. On the basis of the results of this survey, an experiment was made to test the effect on lambing performance of pre-lambing supplementation of range-based ewes.Supplementation reduced weight losses in ewes, but the feeding treatments did not produce significant results in terms of lamb birth weights or survival to 10 days. However, there were indications that selective feeding of weak ewes can produce economic benefits, given that the costs of supervising such animals are minimal and the price of grain supplements is low relative to the price of meat.

Secretogranin Ii

Functional variations in the secretogranin III (SCG3) gene are associated with susceptibility to obesity. SCG3 forms secretory granules with orexin, melanin-concentrating hormone (MCH), neuropeptide Y (NPY), and POMC in the hypothalamus. In this study, we screened proteins for SCG3-binding activity and identified secretogranin II (SCG2) using a yeast two-hybrid system. Immunoprecipitation revealed that SCG2 interacts with SCG3. In situ hybridization and immunohistochemistry indicated that SCG2 was highly expressed in the lateral hypothalamic area, paraventricular nucleus, and arcuate nucleus of the hypothalamus. Double-labeling immunohistochemical analysis demonstrated that SCG2 was expressed in orexin-, MCH-, NPY-, and POMC-expressing neurons. SCG2 was also coexpressed with SCG3. Upon introduction into neuroblastoma cells, SCG2 was expressed in the cytosol and formed granule-like structures with SCG3, orexin, NPY, or POMC. SCG3 bound to POMC; however, it did not bind to orexin, MCH, or NPY. By contrast, SCG2 formed aggregates with orexin, MCH, NPY, and POMC. SCG2 may act as a hormone carrier for orexin, MCH, NPY, and POMC by binding with SCG3, which targets proteins to the secretory granules. SCG2 mRNA levels increased along with those of SCG3, orexin, MCH, and NPY after a 24-h fast, suggesting that the SCG2/SCG3 system may respond in an adaptive manner to acute body weight changes. However, this SCG2/SCG3 system appears to be unresponsive to chronic body weight changes, such as diet-induced obesity or obesity in ob/ob mice. We suggest that SCG2, as well as SCG3, may be a potential regulator of food intake based on its capacity to accumulate appetite-related hormones into secretory granules.

Objective. To observe the effect of preventive acupuncture and moxibustion on blood lipid of menopause rats.Methods. Seventy 10-month-old SD rats with estrous cycle disorders were divided into three control groups and four treatment groups (n=10/group) and another ten 3.5-month-old female SD rats were chosen as young control group. Preventive acupuncture and moxibustion were applied at Guanyuan (CV 4). Body weight growth rate has been recorded. Plasma total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), and high density lipoprotein (HDL) levels and uterusE2level were measured.Results. Compared to young control group, plasma TC and LDL increased and uterusE2reduced significantly in 12-month-old control group. Compared to 12-month-old control group, plasma TC and LDL level and body weight growth rate decreased while HDL level increased remarkably in preventive acupuncture 12-month-old group. Compared to 14-month-old control group, plasma TC level and body weight growth rate decreased remarkably in preventive moxibustion 14-month-old group.Conclusions. Preventive acupuncture and moxibustion can significantly decrease the plasma TG and LDL, increase the plasma HDL, and prevent fat accumulation. Our finding suggests that preventive acupuncture and moxibustion have beneficial effects on blood lipid. Different treatment effects were found between preventive acupuncture and preventive moxibustion.
