Lipid metabolism, fatty acid composition and meat quality in broilers supplemented with increasing levels of defrosted black soldier fly larvae

A feeding experiment was conducted to investigate the impact of defrosted whole black soldier fly larvae (BSFL) broilers in increasing levels ration on blood metabolites, carcass characteristics (CC) and changes fatty acid (FA) composition plasma, muscle abdominal fat. Day-old chicks (Ross-308; n=252) were assigned one four groups each with 6 replicate pens (10-11 birds/pen). The birds fed either a demand-oriented age-specific control (CON) diet had no access BSFL, or CON plus BSFL at 10% (L10), 20% (L20) 30% (L30) feed intake. At weeks (wk) 4 6, (2 per pen) slaughtered collect blood, breast muscle, fat samples determine CC. Plasma triglyceride concentrations increased dose dependent manner compared (P<0.05). L30 L20 higher plasma non-esterified FA than There differences slaughter weight CC between (P>0.05). Broilers highest saturated proportion lowest monounsaturated tissue total polyunsaturated lower In fat, conjugated linoleic (isomer C18:2cis-9, trans-11) followed by L10 Overall, could be included broiler diets up promote sustainability farming without adverse effects weight, meat quality compositions, whereas, inclusion level (i.e. 30%) daily associated altered meat.
