      castration in chicken broilers fed with linseed or sunflower oil.

AB  - The aims of this study were to investigate the influence of the short-term 
      addition of sunflower and linseed oil and castration on fatty acid composition 
      and desaturation indexes in chicken broilers. Forty-eight male Ross 308 chicken 
      broilers were supplemented with 5% of sunflower or linseed oil. The four 
      experimental groups were linseed oil supplementation and castration (LC), linseed 
      oil without castration (LN), sunflower oil and castration (SC) and sunflower oil 
      without castration (SN). There was no significant influence of castration or oil 
      supplement on live weights, weight gain, feed intake or feed conversion. 
      Castration resulted in an increase in polyunsaturated fatty acids (PUFA), total 
      n3, n6, measured desaturation indexes and a decrease in the saturated fatty acid 
      (SFA) and monounsaturated fatty acid (MUFA) content of abdominal fat. In breast 
      muscle, castration increased PUFA and 18:3n3 values, while in the liver tissue, 
      castration did not influence the parameters measured. Linseed oil supplementation 
      significantly increased 18:3n3, n3 long chain polyunsaturated fatty acids (LC 
      PUFA), total n3 and decreased total n6, n6/n3 ratio, and 20:4n6 content. Values 
      for 20:4n6 were the highest in SC and the lowest in the LC group. Linseed oil 
      also significantly decreased ∆5 and ∆4 desaturation indexes in the thighs and ∆5 
      and ∆5, 6 in abdominal fat and the liver. These results suggest that short-term 
      supplementation of basal diet with 5% of linseed oil could significantly increase 
      n3 LC PUFA and decrease n6/n3 ratio content in the edible tissues of chicken 
      broilers, without adverse effects on growth performance. Meanwhile, castration 
      only improved fatty acid profile in abdominal fat, which is not nutritionally 
      important. The interactions observed between basal diet, supplemented oil, sex 
      hormones and other non-nutritional factors must be elucidated in future trials in 
      order to correctly predict the nutritional value of linseed-fed poultry.
