AbstractObjectiveTo estimate the daily dietary energy intake for me to maintain a constant body weight. How hard can it be?DesignVery introspective study.SettingAt home. In lockdown. (Except every Tuesday afternoon and Saturday morning, when I went for a run.)ParticipantsMe. n=1.Main outcome measuresMy weight, measured each day.ResultsSleeping, I shed about a kilogram each night (1.07 (SD 0.25) kg). Running 5 km, I shed about half a kilogram (0.57 (SD 0.15) kg). My daily equilibrium energy intake is about 10 000 kJ (10 286 (SD 201) kJ). Every kJ above (or below) 10 000 kJ adds (or subtracts) about 40 mg (35.4 (SD 3.2) mg).ConclusionsBody weight data show persistent variability, even when the screws of control are tightened and tightened.

Forty crossbred lambs (20 rams, 20 ewes) were penned in two groups (equal numbers of each sex) and fed a pelleted ration either ad libitum (H) or 70% of expected ad libitum intake (70% H). Ten lambs (5 rams, 5 ewes) from both groups (H and 70% H) were slaughtered after 40 days on feed while the remaining lambs were slaughtered after 61 days on feed. All lambs were measured for carcass leanness using an EMME machine immediately prior to slaughter. The offal components were weighed fresh and the alimentary tract was emptied of digesta. One side of each carcass was broken into four cuts (leg, loin, rib, shoulder) which were further separated into fat, muscle and bone. EMME numbers only marginally increased the amount of explained variation in the prediction of lean weight over that provided by liveweight alone. Growth coefficients between sexes and intake groups (H, 70% H) for the offal components relative to empty body weight were homogeneous, indicating that sex and dietary energy intake did not affect the relative growth of the offal components. Ram lambs had heavier heads and smaller intestines than ewe lambs, but contained less caul and mesenteric fat than ewe lambs at the same empty body weight. Lambs fed H had a greater weight of pelt, liver and caul fat, but had a lower warm carcass weight and less mesenteric fat than lambs fed 70% H at the same empty body weight. Growth coefficients between sexes and intake groups for the carcass tissues relative to physically separated tissue weights (muscle, bone, fat) were homogeneous, which indicated that sex and intake did not affect the relative growth of the carcass tissues. Ram lamb carcasses had a greater weight of muscle in the shoulder and less muscle in the leg than ewe lamb carcasses at the same carcass muscle weight. Dietary energy intake had small but statistically significant effects on carcass muscle distribution. Lambs fed 70% H produced carcasses with proportionally more muscle in the leg and less muscle in the loin and shoulder than lambs fed H at the same carcass muscle weight. Sex and dietary energy intake had minor effects on carcass bone and fat distribution. Key words: Lambs, carcass, offal, fat, EMME

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.

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.
