“…The observed clearance rates in the ponies are comparable with those reported for horses by Moser et al., (1993). There was no significant difference between the clearance rates for the ration with MCT vs. that with soya bean oil.…”

“…Triton WR 1339 (oxyethylated t ‐octyl‐phenol polymethylene polymer) selectively inhibits LPL so that plasma triacylglycerols accumulate, the rate of accumulation being an index of plasma triacylgycerol production ( Borensztajn et al., 1976). The elimination of exogenous triacylglycerols from the blood was determined using the artificial fat emulsion Intralipid ® (Fresenius Kabi Nederland BV's Hertogenbosch, the Netherlands), which is considered a valid method to assess the removal rate of endogenous plasma triacylglycerols ( Moser et al., 1993; Rössner et al., 1974).…”

The hypothesis was tested that feeding ponies a diet containing medium-chain triacylglcyerols (MCT) instead of soya bean oil causes an increase in the production of plasma triacylglycerols, which, under steady-state conditions, is associated with an increased clearance of triacylglycerols. Six ponies were fed rations containing either MCT or an isoenergetic amount of soya bean oil according to a cross-over design. The concentration of MCT in the total dietary dry matter was about 13%. When the ponies were fed the diets for 3 weeks, plasma triacylglycerol concentrations were 0.42 +/- 0.09 and 0.17 +/- 0.03 mmol/l (mean +/- SE, n = 6; p < 0.05) for the MCT and soya bean-oil treatment, respectively. Plasma triacylglycerol production was assessed using the Triton method and clearance with the use of Intralipid(R) infusion. Plasma triacylglycerol production was 2.91 +/- 0.88 and 0.50 +/- 0.14 micromol/l.min (means +/- SE, n = 4; p < 0.05) for the diets containing MCT and soya bean oil, respectively. It is suggested that the calculated rates of triacylglycerol production are underestimated, the deviation being greatest when the ponies were fed the ration of soya bean oil. Triacylglycerol clearance rates were calculated on the basis of group mean values for both the fractional clearance rate and the baseline levels of plasma triacylglycerols; the values were 4.28 and 3.52 micromol/l.min for MCT and soya bean oil feeding, respectively. The mean, absolute clearance rates as based on those found in individual ponies did not show an increase when the diet with MCT was fed. Nevertheless, it is concluded that the data obtained support our hypothesis.

“…It is known that, in the adult horse, the transport of the various lipoprotein fractions is dissimilar to that in other mammals, because an adult horse does not appear to have any chylomicron lipoproteins (91). The activity of lipoprotein lipase (assessed following administration of heparin) appears to be lower than that in man (92), and triglyceride infused into horses has a far longer half-life than when infused into other animal species (58). The horse also appears to have far lower carnitine palmitoyl transferase activities than man does (79a).…”

This review outlines the energy sources available to the horse, from its diet and from its body stores, at rest and while exercising. It looks at the current ways of describing the energy potential of diets fed to horses and discusses the relative advantages and disadvantages of the digestible energy and net energy systems. The more empirical net energy system for calculating the energy available for maintenance and work is compared with a more physiological partitioning system. Finally, the energy requirements for maintenance and exercise are discussed, together with how they may be practically determined and achieved through different diets.

The homology of a novel polypeptide with stress protein characteristics in embryonic mice brain and in the hypothalamus of caloric restricted rats as determined by ultramicro western blotting

A novel protein (p34) was observed in polyacrylamide gel fluorographs of gestation day 13 embryonic mouse brain following retinoic acid dosing of dams. Another p34 polypeptide with identical gel migratory characteristics was seen in the hypothalamus of old caloric restricted rats after "food deprivation stress". Western blotting, employing an ultramicro trans-blot cell developed in our laboratory, detected identical immunochemical determinants between these proteins, verifying their homology. Peptide mapping and Western blotting further validated the uniqueness of p34 compared with other stress proteins including heme oxygenase.
