Whole flaxseed, reduced energy, HS, and meat quality.Abstract
This study aimed to assess the impact of heat stress (HS) on broiler chickens provided with a low-energy diet including whole flaxseed, focusing on carcass characteristics and meat quality. A total of 250 one-day-old Ross 308 broiler chicks were randomly allocated into five groups (50 chicks per group), with two replicates for each group. The negative control treatment (T1) received a basal diet devoid of HS. The second treatment fed a basal diet under HS as a positive control (T2). In the third experiment, they fed a basal diet, including whole flaxseed, under heat-stress conditions (T3). The fourth treatment consisted of providing a low-energy diet with whole flaxseed under HS (T4). The fifth intervention was a reduced energy diet administered under HS (T5). The carcass characteristics and edible entrails in the T3 and T4 groups showed a significant improvement (P≤0.05) compared to the control groups. The meat quality in the T3 and T4 groups was considerably enhanced (P≤0.05) due to an increase in omega-3 fatty acid levels [α-linolenic acid, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA)], as determined by GC mass spectrometry compared to the control group that had a corn-soybean diet. In conclusion, incorporating whole flaxseeds into a low-energy diet during HS augmented broiler chickens’ productivity, improved carcass characteristics, and elevated omega-3 concentrations in the meat.
