Megjegyzések:	The analysis of the element composition of weed seeds and shoots could provide new data for their biological and ecological assessment. In the present study, seed samples of 30 weed species from different plant families were analysed for macronutrients (K, Ca, Mg, N, P, S) and high variability was found. There was a considerable difference in the N content of weed seeds, with the highest value for Asclepias syriaca and the lowest for Xanthium spinosum. The macroelement ratio also exhibited a wide range of values, e.g. the N to S ratio varied from 0.2 to 14.2. When crop seed data were compared to those of weed seeds from the same family, the K, Ca, Mg, P and S concentrations in weed seeds were found to be significantly higher in many cases. There were significant differences both in the macroelement concentrations and, in some cases, in the nutrient ratios of weed seeds from different plant families. Significant differences were found for K, Mg, P and S, and for the N/S and Ca/P ratios. This was confirmed by PCA, which illustrated not only differences between weed species, but also the fact that weed plants from the same family formed groups.

Cím:	Dietary manipulation to increase the concentration of n-3 fatty acids in milk fat / Süli Ágnes, Garipoglu Ali Vaiz, Csapó János, Béri Béla, Vargáné Visi Éva, Mikóné Jónás Edit

Megjegyzések:	Linseed is an excellent source of PUFA, especially linolenic acid (18:3n-3), but it is not commonly used in dairy diet in Hungary. Aim of this study was to investigate the effect of the supplemented whole linseed on fatty acid profile of milk fat, with particular reference to health promoting components (?-linolenic acid). A total of thirty multiparous Holstein cows were used in two dairy farms to determine the effect of feeding whole linseed rich in linolenic (C18:3) fatty acids on fatty acid composition of milk fat. The experiment was conducted on two large-scale dairy farms located in Hajdú-Bihar County (referred to as farm "A" and "B"). Fifteen multiparous Holstein-Friesian (165 average days in milk) on farm A and fifteen multiparous Holstein-Friesian (200 average days in milk) on farm B were randomly allocated to treatment groups to investigate the effect of whole linseed supplementation on the composition of fatty acids of milk fat. The group on farm A and B fed TMR based maize silage without whole linseed during the control-period. In the experimental-period the cows received the same TMR on both farms, but it was supplemented with 2.60% DM of whole linseed on farm A, and 2.16% DM of whole linseed on farm B. The experimental period was four weeks in both farms. The supplementation of whole linseed had no effect (P > 0.05) on the short chain saturated fatty acid (SFA), and most of the medium chain saturated fatty acid. During the trial the oleic acid (18:1c) content in milk fat significantly increased (21.33% at the start, 24.71% after 2 weeks and 22.51% after 4 weeks on farm B, respectively). The proportion of ?-linolenic acid (18:3n-3) increased (P > 0.05) during the experimental period compared to the control period (0.23% at the start, 0.58% after 2 weeks and 0.59% after 4 weeks on farm B). The concentration of long-chain polyunsaturated fatty acids (eicosapentaenoic acid and docosapentaenoic acid) significantly increased in milk fat after 4 weeks on both farms. The n-6/n-3 ratio narrowed from 13.52:1 to 3.83:1 and 3.69:1 on farm B, respectively, but this result was not significant. This study concluded that dietary supplementation of whole linseed decreased the proportion of some SFA and increased the proportion of some MUFA and PUFA.
