“…The double bond index (summation of the weight percentage of each FA in a mixture multiplied by the number of double bonds it contains per molecule divided by 100) has been shown to increase as marrow is sampled from proximal to distal leg bones. Furthermore, the increase in the double bond index correlates most closely with 18:1 n-9 (Meng et al, 1969;Turner, 1979;West & Shaw, 1975). MUFA percentages in the more proximal humerus and femur of three North American ruminants ranged from 40 to 45% of total FA, whereas in the more distal metacarpus and metatarsus, MUFA increased to 70 -75% of total FA (Meng et al, 1969;Turner, 1979;West & Shaw, 1975).…”

Because we sampled marrow from the metatarsus at mid-shaft, our fatty acid composition values are consistent with previous values at similar anatomical sites, but not with values measured more proximally (Meng et al, 1969;Turner, 1979;West & Shaw, 1975).…”

“…The fatty acid composition of marrow in wild ruminants has not been extensively studied; however, data from North American animals shows that the relative degree of saturation decreases distally in both the front and rear legs (Meng et al, 1969;Turner, 1979;West & Shaw, 1975). The double bond index (summation of the weight percentage of each FA in a mixture multiplied by the number of double bonds it contains per molecule divided by 100) has been shown to increase as marrow is sampled from proximal to distal leg bones.…”

“…However, there is scant information for marrow (Meng et al, 1969;Turner, 1979;West & Shaw, 1975) and brain (Crawford et al, 1976). The latter tissues would have comprised a substantial portion of the average dietary lipid intake in pre-agricultural humans (Defleur et al, 1999;Harako, 1981;McArthur, 1960;Silberbauer, 1981;Stefansson, 1960).…”

“…One of the major effects on ruminant fat is the ratio of stearate to oleate, which depends on the location of the fat within the body: the closer to the surface the higher the oleate and the lower the stearate (Meng et al 1969;West and Shaw 1975;Morin 2007;Staerfl et al 2011). Despite the difference in total SFA between free-range chicken, pig and ruminant fat, they contain very similar levels of CISFA, in a range~25%.…”

Abstract.Humans hunt or raise a wide variety of animals for meat, which vary from free-range to intensively reared. These animals form a valuable part of human nutrition. Their tissues, including the fat, contain vitamin and other essential nutrients necessary for health. However, animal fat from ruminants and other land mammals is usually regarded as saturated. The purpose of this review is partly to examine the basis for the saturated fat hypothesis of cardiovascular disease given more recent research, to examine the human health effects of animal fats, and partly to draw into one place the diverse knowledge about animal fat and the effects of fat on metabolism. Mechanistic understanding of the initiation of the fatty streak and atherosclerosis calls into question the avoidance of ruminant or porcine fat. Due to high levels of oleic acid, a low n-6 : n-3 fatty acid ratio in some groups, and the presence of specific micronutrients including vitamins and essential fatty acids, animal fats are of benefit in human nutrition. Animal fats can be obtained in minimally processed form making them a convenient source of energy and micronutrients.

After immersion of the hind limb of the rabbit, up to the lower thigh, in a waterbath, at 1 degree C for 10 to 14 hours under light anesthesia, there was evidence of persistent nerve damage to the tibial nerve, which varied in severity in different animals. Nerve conduction studies, carried out within 24 hours of removal from the bath, showed that in a proportion of the motor and/or afferent fibers, there was conduction failure between the knee and ankle. This was followed, over the next 48 hours, by distal degeneration of the affected fibers. No persistent conduction block was seen. After distal degeneration had occurred, maximal conduction velocity was mildly reduced, suggesting that the fastest-conducting motor and afferent fibers had been particularly affected. Morphological studies confirmed preferential large myelinated fiber degeneration, the earliest lesions being seen in the leg at the level of the upper calf. Limb edema was not seen after cooling, and there was no histological evidence of muscle necrosis or damage to blood vessels. No abnormalities were seen in 4 control animals after hind limb immersion for 12 hours at temperatures of 30 to 35 degrees C. Possible reasons for the proximal site of myelinated nerve fiber damage during hindlimb cooling are discussed.
