Effects of plane of nutrition, growth hormone and unsaturated fat on mammary growth in prepubertal lambs.

Effects of plane of nutrition, growth hormone treatment and dietary polyunsaturated fat on mammary development were assessed in prepubertal ewe lambs. Ten lambs (15.6 kg initial body weight) were assigned to each of four treatment groups. Treatments included: (A) lambs given ad libitum access to a high-energy ration; (G) fed as group A but injected s.c. daily with bovine growth hormone (.08 mg/kg BW); (R) feed intake restricted to achieve a growth rate of about 120 g/d; and (S) given ad libitum access to a ration including a formaldehyde-protected sunflower seed supplement. Diets were isonitrogenous and isocaloric and were fed from about 7 to 22 wk of age. At slaughter, the udder was removed and divided into halves. One udder half was trimmed and the parenchyma was dissected from surrounding stroma for compositional analyses. Final body weight and rate of gain averaged 41.2, 42.8, 27.3 and 46.0 kg, and 251, 267, 112 and 311 g/d for groups A, G, R and S, respectively. In the same treatment order, mammary parenchymal weight averaged 15.3, 20.3, 14.2 and 25.6 g. Parenchymal dry, fat-free tissue and DNA content were 1.7, 2.5, 1.3 g and 12.6, 24.1, 10.4 and 18.8 mg, respectively. Mammary parenchymal development was stimulated by polyunsaturated fat but was not affected by plane of nutrition. Supplemental dietary lipid may promote mammogenesis in ruminants.

Effects of plane of nutrition, growth hormone and unsaturated fat on growth hormone, insulin and prolactin receptors in prepubertal lambs.

The influence of plane of nutrition, growth hormone (GH) treatment and dietary polyunsaturated fat on serum concentrations of GH and insulin (INS) and binding capacities of GH, INS and prolactin (PRL) in liver, mammary parenchyma and adipose tissue was assessed in prepubertal ewe lambs. Ten lambs were assigned to each of four treatment groups. Treatments included: (A) lambs with ad libitum access to a high-energy ration; (G) lambs fed as group A and treated with bovine GH (.08 mg/kg/d); (R) lambs with feed intake restricted to limit ADG to about 120 g; and (S) lambs with ad libitum access to a ration including formaldehyde-protected sunflower seed. Diets, all approximately isonitrogenous and isocaloric, were fed from about 7 to 22 wk of age. Weekly blood samples were collected during wk 6 to 14 of the trial. Averaged across sampling dates, mean serum concentrations of GH were elevated in G lambs (P less than .05) and INS concentrations differed in the order G greater than A greater than R = S (P less than .05). Crude membranes for binding assays were prepared from liver, mammary parenchyma and adipose tissue. Mean concentrations of GH receptors in liver and PRL receptors in mammary parenchyma were elevated in group S lambs (P less than .01). Dietary polyunsaturated fat increased the number of GH receptors in liver and PRL receptors in mammary parenchyma. Increased availability of receptors may mediate the stimulation of mammary growth observed in lambs fed polyunsaturated fat.

Lipoperoxides in organs of vitamin E deficient rats fed large amounts of highly unsaturated fats.

Rats were fed diets containing 10% cod liver oil with and without a supplement of tocopherol acetate for 32 weeks. The determination of peroxides in lipid extracts of adipose tissue, liver, heart and skeletal muscle by different methods was attempted. High amounts of peroxides were found only in adipose tissue of vitamin E deficient animals. Small values were found in other tissues of both groups. The problem whether the organs contain true lipoperoxides, or some other substances are responsible for the peroxide estimates, is discussed.

[Influence of bioactive dietary supplement--dietary unsaturated fats--on immune status of patients with myocardial ischemia and impaired glucose tolerance].

Immune status measured by the flow cytrometric analysis under the ischemic heart disease and IHD with impaired glucose tolerance has been found to be altered in B cells as well as in T lymphocytes in some cases. Having received the diet supplemented by PUFA "Eicolen", IHD patients present with the restored immune status. Patients with IHD and impaired glucose tolerance did not present with any significant modifications in immune status after PUFA "Eicolen" supplementation.
