The effect of flaxseed meal on broiler performance, carcass characteristics, alpha-linolenic acid contents, and organoleptic characteristics of chicken meat was studied during a 42 day experiment. Broiler chicks were randomly allotted to 4 experimental groups and fed iso-energetic and iso-nitrogenous diets containing flaxseed meal at 0, 5, 10 and 15%. Flaxseed meal did not affect the weekly body weight of broiler chicks during the first two weeks but thereafter weekly body weight reduced among flaxseed meal groups. At the end of $6^{th}$ week, birds fed on 15% flaxseed meal showed a reduction of 8% in body weight compared to the control group. Control group had significantly higher weight gain with slightly higher feed consumption and better feed conversion ratio (FCR), protein efficiency ratio (PER), and energy efficiency ratio (EER) than the flaxseed meal groups. Among the treatments, birds of 5 and 10% flaxseed meal groups had significantly better FCR, PER and EER compared to those of the 15% flaxseed meal group. The carcass characteristics data indicated a significant reduction in the eviscerated weight and breast yield at 15% flaxseed meal in the diet as compared to other dietary groups. However, the alpha-linolenic acid content in both breast and thigh meat was higher with an increasing level of flaxseed meal in the diets without affecting the sensory acceptability of meat. Based on the present study, up to 10% of flaxseed meal may be used in broiler diet to enhance the alpha-linolenic acid content in the broiler meat.

This study examined the antimicrobial activity of flaxseed meal extract (FME) against Staphylococcus aureus and Escherichia coli O157:H7 inoculated on red mustard. With the treatment of 0.7% FME for 3 min, the reduction levels of S. aureus and E. coli O157:H7 populations were 1.23 and 1.83 log CFU/g, respectively. In addition, the combined treatment of 0.7% FME at $50^{\circ}C$ for 3 min reduced the populations of the pathogenic bacteria by 2.28 and 2.41 log CFU/g, respectively. The color and the vitamin C content were not significantly different between treatments. Thus, FME can be used as a novel antimicrobial agent in fresh-cut vegetables.

Objective: The present study evaluated the effect of flaxseed meal degraded by a protease, Lactobacillus plantarum, or both on the growth performance, nutrient digestibility, and health status of broilers. Methods: There were four diets containing flaxseed meals in its non-degraded form (control, CON), degraded with 3,000 U/kg of protease (enzymatic, ELM), 1.0×10⁹ CFU/kg of Lactobacillus plantarum (fermented, FLM), or both (dual-degraded, DLM). Each form of flaxseed meals was added at 15% of diet. A total of 480 yellow-feathered broilers at 22 d of age were distributed into 4 groups with 6 replicates of 20 chickens each. The feeding trial lasted for 42 d. Growth performance, apparent fecal digestibility (dry matter, energy, crude protein, and ash), and serum immunoglobins and antioxidases were determined at 42 and 63 d of age. Results: Results showed that ELM, FLM, and DLM increased (p<0.001) the contents of peptides and decreased (p<0.001) cyanogenic glycosides, compared to CON. The diets with degraded flaxseed meals increased (p<0.05) feed intake and body weight gain throughout the feeding trial, and the digestibility of energy, crude protein, and ash at the end of feeding trial. Furthermore, all degraded groups enhanced (p<0.05) broiler health status by increasing serum immunoglobulins A and G. Additinally, DLM showed more pronounced effects (p<0.05) on these parameters than ELM or FLM. Conclusion: Flaxseed meals degraded by enzymolysis, fermentation, or both had improved nutrition and application in broilers.

본 실험은 부존사료자원을 토종닭에 이용하여 EPA 및 DHA와 같은 ${\omega}-3$계 다가불포화지방산을 함유하는 고품질 계육을 생산하기 위한 목적으로 실시하였다. 45일령의 재래종 암수탉을 공시하여 20일간 사양실험을 수행하였다. 일반시판사료를 사용한 대조구와 임자박 10% 첨가구(PM), 임자박 10% 및 아마종실 5% 첨가구(PM+FS), 임자박 10%, 아마종실 5% 그리고 어유 1% 첨가구(PM+FS+FO)로 나누어, 4처리 3반복 그리고 반복당 20수씩 총 240수를 공시하였다. 실험 종료 시체중, 증체량, 사료섭취량 및 사료 요구율 등 생산성과 관련된 항목에서는 처리간에 큰 차이는 관찰되지 않았다. 대조구에 비해 모든 시험구에서 산패도 수치가 약간 높게 나타났으나 처리간에 유의차는 인정되지 않았다. 계육 내의 지방산 조성을 조사한 결과에서 ${\omega}-6$계 불포화지방산의 비율은 처리간에 큰 차이가 관찰되지 않았다. 임자박, 아마종실 및 어유 첨가에 의해 ${\omega}-3$계 불포화지방산(C18:3 ${\omega}-3$, EPA, DHA)의 비율이 증가하는 경향 및 유의하게 증가하는 결과가 나타났다. 특히 EPA와 DHA는 어유를 첨가한 PM+FS+FO구에서 다른 구와 비교하여 유의하게 증가하였다. 본 연구의 결과, 임자박, 아마종실 및 어유를 일반시판사료에 적정량 혼합 급여하는 사료적 처리를 통해 재래종 닭에서 조직 내 총 ${\omega}-3$계 불포화지방산 및 DHA 함량을 증가시킬 수 있었으며, 이렇게 생산된 고부가가치 계육이 ${\omega}-3$계 불포화지방산의 좋은 공급원이 될 수 있을 것으로 사료되었다.
