Effect Of Feeding

Abstract. Camelina (Camelina sativa L. Crantz) and hemp (Cannabis sativa L.) seed cakes are rich sources of n-3 polyunsaturated fatty acids (PUFAs). This study was carried out to investigate the effects of Camelina and hempseed cakes in the diet of ducks on the intramuscular fatty acid profile. Male ducks (n = 99) were randomly allocated to 3 dietary treatments: Control or C group (wheat–soybean-meal–barley-based diet with 15–20 % rapeseed cake), Experimental 1 or HEM group (with hempseed cake added at 15–20 % instead of rapeseed cake), and Experimental 2 or CAM group (with Camelina cake added at 15–20 % instead of rapeseed cake). All groups received the diets ad libitum. At 49 days of age, six ducks from each group were slaughtered for analysis of the fatty acid composition in the breast and leg muscles. Feeding ducks with the diet enriched with Camelina cake resulted in significantly higher amounts of n-3 α-linolenic fatty acid (ALA) (P≤0.01) and total n-3 PUFA (P≤0.01) in breast and leg muscles, while eicosatrienoic fatty acid (ETE) (P≤ 0.01) was higher in the leg muscle. The ratios of n-6 ∕ n-3 and linoleic ∕ α-linolenic fatty acids (P≤ 0.01) decreased significantly compared to the Control and HEM groups of ducks. Feeding ducks with the diet enriched with hempseed cake resulted in significantly higher amounts of linoleic (LA) (P≤ 0.01), total n-6 PUFA (P≤ 0.05–P≤ 0.01) and n-6 γ-linolenic (GLA) (P≤ 0.01) fatty acid. Our study showed that using Camelina cake as supplementation in duck diets opens a possibility to develop functional food, i.e. meat with a significantly higher content of ALA, total n-3 PUFA and the lowest ratios of n-6 ∕ n-3 fatty acids in ducks' muscles. A duck diet with hempseed cake produces exceptional-quality meat with an enriched content of n-6 GLA.

Effect Of Feeding

Recently, the quality of lamb meat has been regarded with attention to the content of intramuscular fat, and its fatty acid profile. These indicators are determined by the feed administered to the animals. Apparently, the type of silage used in animal nutrition may be important. The objective of this study was to determine the effect of feeding lambs with silages produced from different plant species on selected meat quality traits. The experiment was conducted on 24 ram lambs, divided into 3 equal groups fed with red clover silage, alfalfa silage, and grass silage, respectively. After 60 days of fattening, the lambs were slaughtered. Samples collected from musculus longissimus lumborum were assayed for: contents of intramuscular fat, cholesterol, the vitamins retinol and α-tocopherol, and the fatty acid profile of intramuscular fat. The meat of lambs fed red clover silage was characterized by a higher content of fat compared to lambs receiving grass silage (P ≤ 0.05). The concentration of vitamin E in the group fed grass silage was the highest and differed significantly (P ≤ 0.01) compared to the group fed alfalfa silage. Intramuscular fat of lambs fed red clover silage contained more polyunsaturated fatty acids n-3 and was characterized by a lower ratio of polyunsaturated fatty acids n-6:n-3 compared to the lambs fed grass silage. The concentration of conjugated linoleic acid was higher in lambs fed grass silage compared to fat of lambs from the other groups (P ≤ 0.05). Feeding lambs with silages produced from various plant species had a positive effect on traits characterizing the health quality of meat. Until now, only a few studies have been conducted in this species; this is the first such comprehensive study in sheep.
