Evaluation of the Production Performance and the Meat Quality of Chickens Reared in Organic System. As Affected by the Inclusion of Calliphora sp. in the Diet

Abstract

The use of insects can be a possible source of protein. This study uses Calliphora sp. larvae (CLM) as a protein source in 320 one-day-old medium-growing male chicks (RedBro) during their first month of life. Chickens were randomly assigned to four dietary treatments. Each group consisted of 10 animals, and a total of 8 replicas. Control group was fed with a certified organic feed. The experimental treatments were supplemented with 5% (T2), 10% (T3), or 15% (T4) of CLM, reducing in each case the corresponding percentage of feed quantity. Productive development and meat quality were analyzed, and near infrared spectroscopy (NIRS) was used as a tool for classifying the samples. Chickens of T4 showed greater final body weight and total average daily gain, but they reduced consumption and feed conversion ratio (FCR). The chicken breast meat of T4 had lower cooking losses and higher palmitoleic acid content (p < 0.01). NIRS classified correct 92.4% of samples according to the food received. CLM is presented as a potential ingredient for the diet of medium-slow growing chickens raised in organic systems.

Performance, Egg Quality, and Yolk Antioxidant Capacity of the Laying Quail in Response to Dietary Choline Levels

“…A thiobarbituric acid reactive substances (TBARS) assay was performed as a modified method described by Kilic and Richards [ 24 ] and Sarmiento-Garcia et al [ 25 ] in triplicate from each group to determine lipid peroxidation. A two-gram sample was taken from the yolk and added to 12 mL of the trichloroacetic acid (TCA) solution (7.5% TCA, 0.1% EDTA, 0.1% Propyl gallate).…”

Performance of Slow-Growing Chickens Fed with Tenebrio molitor Larval Meal as a Full Replacement for Soybean Meal

“…Therefore, the use of non-soybean protein sources in poultry diets is essential to avoiding negative social, economic and ecological impacts arising from large-scale soybean imports. Currently, there is an emerging trend towards the use of alternative feeds to soybeans for poultry which are capable of achieving feed efficiency and feed quality equivalent or superior to soyabean feeds [ 6 , 7 , 8 ].…”

“…Therefore, it is very likely that chickens would do well with insect meal as part of their dietary rations [ 10 ]. Insects are claimed to be an alternative and sustainable nutritional source for farm animals, including poultry [ 8 , 11 , 12 ]. It is a high-protein feed [ 13 ], which also has a considerable amount of unsaturated fats (specifically linoleic and linolenic acids), and large amounts vitamins, fiber and minerals [ 14 , 15 ].…”

Study on the effect and mechanism of chicken breast on the gel properties of silver carp (Hypophthalmichtys molitrix) surimi

“…also reported that the enhancement of the mixed gel might be a result of the interaction between fish and chicken proteins at a setting temperature of 45 °C. The abundant phospholipids in chicken often form a phospholipid bilayer with proteins, glycolipids, cholesterol and other molecules 26 . During heating, the hydrophilic group of phospholipids may combine with the hydrophobic groups of proteins resulting in a decrease in gel strength of the mixed gels.…”

“…The abundant phospholipids in chicken often form a phospholipid bilayer with proteins, glycolipids, cholesterol and other molecules. 26 During heating, the hydrophilic group of phospholipids may combine with the hydrophobic groups of proteins resulting in a decrease in gel strength of the mixed gels. Chicken breast contains a large number of myofibrillar protein bundles, and this dense structure resulted in myogenic fibrillar proteins not being easily separated.…”
