“…Except for leg weight results, the results are in agreement with what (Esteve and Khan, 2018) who announced in their study on adding different sources of liquid methionine that carcass yields, as a percentage of live body weight, were not affected by dietary treatments. The results of the carcass traits in this study are inconsistent with what was found by (Kim et al, 2019), they confirmed that there were significant differences between the different nutritional factors in the carcass parts when feeding various sources of liquid methionine to broiler chicks. Some of the results achieved in this study are not consistent with what is found by (Conde et al, 2016), where they emphasized in their study on broiler chicks the sources of methionine had significant (P ≤ 0.05) effects on the liver and heart weight, while methionine levels significantly influenced (P ≤ 0.05) the liver and gizzard weight.…”

The effect of a liquid methionine source provided through the drinking water on broiler chick performance, water intake, and carcass characteristics were studied using 264 unsexed broiler chicks (Ross 308, 7 days old). Methionine was added within three replicates in four treatments with 22 birds in each as follows: T1 (control treatment): without adding liquid methionine, T2: adding 0.25 ml of liquid methionine/litter of drinking water, T3: adding 0.50 ml of liquid methionine/litter of drinking water, and T4: adding 0.75 ml of liquid methionine/litter of drinking water. Live body weight, body weight gain, feed intake, feed conversion ratio, water intake, and carcass traits were taken. The results showed that adding liquid methionine in drinking water were significantly increased (P≤0.05) live body weight, total feed intake, and body weight gain, as well as carcass traits also were significantly different among the treatments. Within the limits of the study, liquid DL-methionine provided in the drinking water was effectively assimilated by broiler chicks and increased total methionine intake, which increased the growth rate of the chicks.

“…Immediately after scanning the broiler carcasses, breast muscles (pectoralis major and minor), drumsticks (muscle), and thighs (muscle) were removed from the carcasses and individually weighed to determine cut yield. Thigh, drumstick, and breast meat yields were expressed as a percentage of the live body weight as described previously [ 27 , 28 , 29 ]. The live body weight is described and published as individual body weight in de Souza et al [ 5 ].…”

We evaluated the effects of full-fat black soldier fly larvae (BSFL) on broiler carcass composition, cut yield, and breast meat quality. Broilers were fed for 42 days with up to 20% dietary inclusion of BSFL (0, 5, 10, 15, and 20%). On day 42, 120 broilers were slaughtered, and images were taken using computed tomography. Breasts, drumsticks, and thighs were collected for cut yield determination. The pH, color, lipid oxidation, cooking loss, shear force, amino acid profile, and fatty acid profile of the breast meat were assessed. There was no dietary effect on carcass composition or meat quality parameters except for fatty and amino acids compositions. When 20% BSFL was included in the diet, individual fatty and amino acids, such as lauric and myristic acids, aspartic acid, glutamine, and lysine, increased by 22.0-, 5.50-, 1.08-, 1.06-, and 1.06-fold, respectively (p < 0.05). Although total polyunsaturated fatty acids decreased, eicosapentaenoic fatty acids (EPA) increased by 78% in the 20% BSFL inclusion group. In conclusion, up to 20%, dietary full-fat BSFL did not affect key meat characteristics but positively increased the levels of the health-claimable omega-3 fatty acid EPA.

“…Information about the relative biological efficacy (RBE) of MHA‐FA compared with dl ‐Met is a relevant factor for cost‐effective purchasing, feed formulation and animal production (Kim et al., 2019 ; Sauer et al., 2008 ). Through the years, there's been considerable research into the potency and usage of these various Met sources, and it has been reported that both Met sources allow for accurate balancing of the dietary SAAs in poultry nutrition.…”

BackgroundIn the broiler's diets based on corn–soya bean meal, methionine (Met) and cystine (Cys), known as sulphur amino acids (SAAs), are the first limiting indispensable amino acids because of their limited presence, which are supplemented with different synthetic sources. Evaluation of the biological effectiveness of these sources can be important in their correct replacement, especially in the starter and growth diets.ObjectivesThe current study was done to assess the relative biological efficacy (RBE) of liquid Met hydroxy analogue‐free acid (MHA‐FA) in comparison with dl‐Met (dl‐Met) based on broiler performance traits at different levels of digestible SAA in the 1–11 (starter) and 11–25 (grower) days of age periods.MethodsTwo experiments were developed with treatments consisting of a basal diet without Met addition that met the nutrient and energy requirements of broilers with the exception of SAAs (Met + Cys) and five increasing Met doses for both sources (dl‐Met and/or MHA‐FA), resulting in digestible SAA concentrations from 0.62% to 1.02% of diet in the starter period (Trial 1) and 0.59% to 0.94% of diet in the grower period (Trial 2). The multi‐linear regression model and slope ratio method were employed to calculate the RBE of MHA‐FA compared with dl‐Met for measured variables.ResultsIn both experiments, the results obtained during the starter and grower periods with the different Met supplementations show significant growth responses to digestible SAAs levels. By increasing dietary dl‐Met and/or MHA‐FA levels, the growth performance traits and immune responses were improved (quadratic; p < 0.05). The RBE of MHA‐FA compared to dl‐Met on an equimolar basis was estimated 66%–89% (59%–79% on a weight‐to‐weight basis).ConclusionsIt is concluded that the RBE of MHA‐FA in comparison with dl‐Met depends on broiler chicken age and what attribute is being evaluated.
