“…Oleic acid is the predominant FA in TM larvae (Paul et al ., 2017) and increased C18:1 c 9 and ΣMUFA deposition in the breast muscle of chickens fed a diet containing TM oil when compared with a diet containing soybean oil has recently been reported by Kierończyk et al . (2018). These authors also showed a significant reduction in ΣSFA in breast muscle when using dietary TM oil.…”

This study evaluated the effects of a diet containing yellow mealworm (Tenebrio molitor L.; TM) larva meal on quality parameters (pH24, color and drip losses), proximate composition and fatty acid (FA) profile of meat from free-range chickens. A total of 140 medium-growing hybrid female chickens were free-range reared and randomly allotted to two dietary treatments: a control group and a TM group, in which TM meal was included at 75 g kg−1 as fed in substitution of corn gluten meal. Each group consisted of five pens as replicates, with 14 chicks per pen. At 97 days of age, ten birds (two birds/pen) from each feeding group were slaughtered at a commercial abattoir. Quality parameters and proximate composition of breast and thigh meat were not affected by treatment. The effects of dietary TM larva meal on the FA profile of thigh meat were negligible. Breast meat from TM-fed chickens showed higher oleic and α-linolenic acid percentages as well as lower atherogenicity and thrombogenicity indexes. In conclusion, this study demonstrated that TM inclusion in diets for free-range chickens did not prejudice meat quality traits. The obtained results confirm that TM can be considered a promising insect protein source for the poultry feed industry.

“…Feed and water were provided ad libitum throughout the 30-day-feeding trial, and light was provided 23 h/D. The 30-day-feeding trial was considered sufficient to elucidate the biological effect of insect oils, if any, in broiler chickens as reported elsewhere ( Kierończyk et al., 2018 ). Body weight and feed intake by pen were monitored at the beginning and 15 and 30 D of experiment.…”

The present study was conducted to investigate growth performance, carcass characteristics, short-chain fatty acids, fatty acid composition in abdominal fat, and serum parameters in broiler chickens fed diets containing corn oil, coconut oil, or black soldier fly larvae ( BSFL ) oil at the level of 50 g per kg of diet during the 30-day-feeding period. A total 450 one-day-old male broiler chicks (Ross 308) were randomly allocated to one of 3 dietary groups. Each treatment had 10 replicates with 15 chicks per replicate. Feed conversion ratio was decreased in the coconut and BSFL oil group compared with the corn oil group. Dietary BSFL oil increased ileal weight-to-length ratio at day 30 after hatch. Dietary BSFL oil increased significantly ileal branched-chain fatty acid ( P < 0.05) and moderately total short-chain fatty acid in 15-day-old broilers ( P = 0.074). At day 30, ileal propionate was highest in the coconut oil group but cecal propionate was highest ( P < 0.05) in the BSFL oil group. Fatty acid composition of abdominal fat was affected by dietary fat sources. Especially, chickens fed diets containing coconut oil or BSFL oil had higher contents ( P < 0.05) of saturated fatty acid being dominant in lauric and myristic acids compared with those fed on corn oil. On the other hand, the reverse trend was noted ( P < 0.05) as to polyunsaturated fatty acids being dominant in corn oil compared with coconut oil and BSFL oil. Coconut oil vs. corn oil significantly increased total and high-density lipoprotein cholesterol. Finally, BSFL oil vs. corn oil significantly increased total antioxidant capacity in chickens. It is concluded that dietary BSFL oil improves feed conversion ratio and increases the incorporation of medium-chain fatty acids into abdominal fat pad and serum antioxidant capacity in broiler chickens.

“…These fatty acids are transferred to the blood and thus can contribute energy to the body [7][8][9]. Recently, insects have been proposed as an alternative source of protein and fat for broilers, turkeys and laying hens [10][11][12][13][14]. In addition, insects were found to be one of the nutrient factors that can modulate the GIT microbiota populations during full or partial replacement of protein sources [15][16][17][18][19] and as feed additives in the diet of broiler chickens [20].…”

Simple Summary: In animal nutrition, the links among health status, alimentary tract factors and gastrointestinal tract (GIT) integrity are increasing in importance. It has been documented that insects are useful as novel ingredients in poultry diets because they contain bioactive compounds such as chitin, melanin, and antimicrobial peptides, in addition to protein and dietary fat, and these bioactive compounds have been reported to modulate the GIT microbiome. From this perspective, insects could be promising functional feed additives to stimulate GIT health through inhibition of potentially pathogenic bacteria. Therefore, we evaluated the effect of the addition of a small amount of insects to the broiler chicken diet on the GIT microbiota composition and activity. Six experimental groups were used in the current study, i.e., two different levels (0.2% and 0.3%) of yellow mealworm and super mealworm full-fat meals, a positive control with salinomycin addition, and a negative control without any additives. Insect full-fat meals were capable of improving the health status of the birds by a positive reduction in potentially pathogenic bacteria in the cecal digesta and stimulation of the GIT microbiome to produce enzymes, especially glycolytic enzymes.Abstract: This study was conducted to investigate the effect of insect full-fat meals added in relatively small amounts to a complete diet on the coefficients of apparent ileal digestibility, short-chain fatty acid (SCFA) concentrations, bacterial enzymes, and the microbiota community in the cecal digesta of broiler chickens. In total, 600 one-day-old female Ross 308 broiler chicks were randomly assigned to six dietary treatments with 10 replicate pens/treatment and 10 birds/pen. The groups consisted of a negative control (NC) with no additives; a positive control (PC; salinomycin 60 ppm), and supplementation with 0.2% or 0.3% Tenebrio molitor or Zophobas morio full-fat meals. Z. morio (0.2%) addition increased the activities of αand β-glucosidase and α-galactosidase. Dietary insects significantly decreased the cecal counts of the Bacteroides-Prevotella cluster in comparison to those in the NC and PC. Whereas, Clostridium perfringens counts were increased in the broiler chickens subjected to the 0.3% Z. morio treatment. In conclusion, small amounts of full-fat insect meals added to broiler diets were capable of reducing the abundance of potentially pathogenic bacteria, such as the Bacteroides-Prevotella cluster and Clostridium perfringens. In addition, this supplementation was able to stimulate the GIT microbiome to produce enzymes, especially glycolytic enzymes. resources, D.J.; data curation, A.B., B.K. and D.J.; writing-original draft, A.B.; writing-review and editing
