The aim of the study was to evaluate the influence of feeding goats diets with different protein levels (11.4, 13.3 and 16.9%) and a small change of fatty acid contents on the concentrations of trans11C18:1 and conjugated linoleic acid (CLA) isomers in milk. The experimental design was 3 × 3 Latin Square. Each 22-day experimental period consisted of 14 days adaptation to the diets and 8 days for milk...
The influence of dietary conjugated linoleic acid (CLA) isomers (CLAmix) and/or Se as Na2SeO3 (SeIV) or selenized yeast (SeY) on the relative body weight gain (RBWG) of rats, pancreas weight, concentrations of CLA isomers and of other fatty acids (FA) in the pancreas were studied. For 6 weeks, female Wistar rats (aged 8 weeks) were fed ad libitum the Labofeed H diet enriched in 1.5% CLAmix, 0.2 ppm...
The aim of the experiment was to compare the effect of different dietary fat sources on performance, biochemical indices and fatty acid profile in the blood serum of broilers. The study was carried out on 96 male Ross 308 chickens from 1 to 42 day of life, fed diets supplemented with soyabean oil (SO), Nowitol 30 (N) and lard (L). The ratio of UFA/SFA in fat sources was: 4.55 (SO), 4.27 (N), 1.75...
This study investigated the effects of dietary supplementation of conjugated linoleic acid (CLA) on the growth performance, carcass characteristics, muscle quality and fatty acid compositions in the skeletal muscle and backfat of growing-finishing pigs from 39.5 to 108.0 kg. Forty-eight pigs were randomly allotted to four diets containing 0 (control), 0.5, 1.0 or 1.5% of CLA mixture (35.2% cis-9,...
The objective of this study was to determine the physiological effect of supplementing turkey diets with different vegetable oils, i.e. soyabean (S) oil, rapeseed (R) oil and linseed (L) oil, which have different concentrations of polyunsaturated fatty acids (PUFA). The total contents of n-6 PUFA and n-3 PUFA were as follows: diet S, 49.7 and 7.02%, diet R, 33.0 and 7.96%, and diet L, 30.3 and 30...
Conservation breed/line laying hens: Greenleg Partridge (Z-11), Yellowleg Partridge (Ż-33), Rhode Island Red (R-11), Sussex (S-66) and Leghorn (H-22 and G-99), 360 per strain were divided into 2 equal feeding treatment groups. Control groups (C) were fed a standard complete diet, experimental groups (L) were fed a diet with 10% linseed. The experiment was conducted from 37 to 52 weeks of age. Hatching...
Twenty lactating Alpine goats were randomly allocated to two treatment groups to investigate the effect of feeding green maize on the fatty acid profile of milk and cheese. The control goats were fed lucerne hay ad libitum; the other group was fed green maize plants ad libitum; additionally, all animals received 350 g per day per goat concentrate of the same composition. The green maize diet considerably...
