The role of essential fatty acids in human and animal health, growth, and development is a topic of continued interes. A 6-wk study was performed on 80 Tetra SL (56 weeks) laying hens, to determine the nutritional quality of the poultry eggs treated with a a mixture of cereal and oleaginous grains (corn, flax oil, barley and peas - VMLO). The laying hens, housed in an experimental hall with controlled environment (16 light regimen, 20.01±1.44°C temperature; 65±6.38% humidity) were assigned to 2 groups (C and E). The poultry received a conventional feed with the same basic structure (2750 kcal/kg metabolizable energy and 16.5% crude protein). Compared to the C diet (2750 kcal/kg metabolizable energy and 16.5% crude protein) characterized by 0.83 g of a-linolenic acid (C18:3n3), the E diet included 15% VMLO, which resulted in an increase in a-linolenic acid concentration in the diet up to 13.80 g/100g total fatty acids. At the end of the study, 18 eggs/group were collected to determine the PUFA and cholesterol concentrations in yolk. The results obtained for E group eggs, whose concentration in PUFA O3 (5.07±0.546g % total fatty acids) increased significantly (P<0.05) compared to C (1.22±0.139g % total fatty acids), indicated significantly lower values concerning the cholesterol concentration (1.661±0.056 g% dry egg yolk) compared to C (1.865±0.178 g% dry egg yolk). Use of VMLO in poultry feed has positively influenced egg quality without affecting production performance. [ABSTRACT FROM AUTHOR]

A feeding trial was conducted on 75, ROSS 308 broiler chicks (0-42 days), to evaluate the feeding quality of the meat from broilers treated with unconventional food industry by-products. The feeding trial was performed under controlled environmental conditions, under experimental conditions. The broiler chicks were assigned to 3 groups (C; E1 and E2), housed in digestibility cages (5 broiler chicks/cage), which allowed monitoring the production parameters. During the first phase (starter), the broiler chicks received a conventional compound feed formulation. For phases II (grower) and III (finisher), the experimental compound feeds formulations (E1 and E2) included a mixture of cereal and oleaginous grains (corn, flax oil, barley and peas - VMLO) as follows: 4 and 7.5%, respectively, for E1, and 10 and 12.5% respectively, for E2. The dietary concentration of ɷ:3 polyunsaturated fatty acids (ɷ:3 PUFA) in E2 diet increased with the dietary level of VMLO byproduct (4.95% ɷ:3 PUFA for the grower period and 6,10% ɷ:3 PUFA for the finisher period). Six broilers/group were slaughtered at 42 days and breast meat, thigh meat and liver were collected and analysed. The analytical results indicate an improved feeding quality of the broiler meat as showed by significant (P≤0,05) changes in the basic chemical composition of the broiler meat and in the fatty acids profile and cholesterol concentration. The fat level decreased significantly (P≤0,05) in the breast meat from group E2 (0.91±0.09 g fat): 18.75% lower than in group C (1.12±0.07 g fat) and 5.35% lower compared to group E1 (1.06±0.09 g fat). Group E2 also recorded the best values for the omega 3 fatty acids, essential to human health, determined in the breast meat (3.99 g/100g total fatty acids), thigh meat (3.89 g/100g total fatty acids) and liver (5.12 g/100g total fatty acids) samples.
