“…The combined effect of L-Met and DL-Met had a significant (p < 0.05) effect on the liver weight of broilers. Our finding of unaltered heart and gizzard weight due to the combined effect of L-Met and DL-Met is supported by other researchers [45,46] who observed that DL-Met and herbal methionine had no significant effect on the carcass yield, breast meat and eviscerated weight of broilers. The significant differences observed between the heart and liver weight of birds fed different types of amino acid are corroborated by Ahmed and Abbas [45] who observed that dietary supplementation of methionine significantly affected the liver and heart weight.…”

Simple Summary: The current work evaluated the utilization of different sources of methionine either from DL-methionine (DL-Met) or L-methionine (L-Met) using different concentrations of dietary methionine plus cystine (Met + Cyst) in broiler chickens. Results showed that a better edible meat yield could be obtained by supplementing Met + Cyst at the rate of 80% of the digestible lysine.Abstract: The objective of this work was to evaluate the utilization of methionine from DL-methionine (DL-Met) and L-methionine (L-Met) with different levels of dietary methionine plus cystine (Met + Cyst) in broilers. The experimental diets were formulated by using three levels of Met + Cyst, i.e., 74%, 77% and 80% of digestible lysine. Met + Cyst was provided either from DL-Met or L-Met. A total of 450 day-old broilers were divided into six groups (five replicates of 15 birds each) in a 3 × 2 factorial arrangement under completely randomized design. Weight gain (WG), feed intake (FI) and feed conversion ratio (FCR) was determined. At the end of the experiment (35 days), two birds from each replicate were slaughtered to determine carcass characteristics and serum homocysteine. Results indicate that the combined effect of L-Met and DL-Met significantly affected (p < 0.05) the WG in the starter period and FI in the finisher period. Neither source nor level of methionine influenced (p > 0.05) the FI, WG and FCR of broilers during the starter, finisher or overall phase of growth. The interaction between sources and levels of methionine did not influence (p > 0.05) the feed intake, weight gain and FCR during the overall phase of growth. Source of methionine had no (p > 0.05) effect on carcass characteristics. Methionine levels had a significant effect (p < 0.05) on carcass weight, chest weight and thigh weight. The interaction between sources and levels of methionine had a significant (p < 0.05) effect on the liver weight. 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. Finally, it was concluded that if DL-Met and L-Met are included in feed at a standard level, they are equally effective as a source of methionine for broilers.

“…This confirms that methionine aids broilers to meet up with body tissue deposition that is a pre-requisite for rapid growth. Absence of significant difference in daily weight gain is in line with the works of Kaur et al (2013), Egenuka et al (2015) and Ahmed and Abass (2015).…”

“…The broilers whose diets was fortified with 0.2% methionine tended to have consumed more feed (103.02 g) followed by 0.5% (102.22 g), 0.1% (100.00 g), positive control (98.25 g), 0.4% (95.87 g), negative control (94.44 g) and 0.3% (90.32 g).The absence of significant difference in feed intake may be caused by the similarity of the metabolizable energy concentration of the diets since birds eat to satisfy their energy requirements (Onu et al, 2010). Absence of significance agrees with the works of the following authors: Kalbande et al (2009) who supplemented diets of broilers with different levels of methionine; Bouyeh (2012) who tested excess lysine and methionine on the immune system and performance of broilers; Kaur et al (2013) where performance of commercial broilers were compared after replacing Herbomethione® with DLmethionine in their diets; Egenuka et al (2015) where increasing level of dietary level of blood meal and reduced supplementary lysine were tested on performance of broilers and Ahmed and Abass (2015) who evaluated the broiler performance and carcass characteristics when herbal methionine versus dl-methionine were supplemented in broiler diets. Broilers fed diets containing 0.5% methionine fortifications seemed to have higher daily weight gain values (29.89 g), followed by 0.4% (29.84 g), 0.3% (29.78 g), 0.2% (29.63 g), positive control (29.57 g), 0.1% (27.89 g) and negative control (26.28 g).…”

This study was conducted to evaluate the growth performance, dressing percent and carcass composition, organ weights and cost-return analysis of broiler chickens fed methionine-fortified blood meal as replacement for fish meal. Two hundred and ten day-old hybro broiler chicks were allotted to 21 floor pens with 10 birds per pen. Seven experimental diets were formulated for starter and finisher phases respectively. Diets 1 (positive control) and 2 (negative control) contained 3% fish meal and 3% blood meal respectively. Diets 3 to 7 contained 3% blood meal each with 0.1, 0.2, 0.3, 0.4 and 0.5% methionine fortifications, respectively. Each diet was fed as mash to birds in 3 pens in completely randomized design. Results of growth performance showed no significant (p>0.05) differences in average daily feed intake, average daily weight gain and feed conversion ratio but mortality revealed significant (p<0.05) difference. Final body weight and dressing percentage were not affected by the treatment (p>0.05). Significant (p<0.05) differences were observed in the moisture, crude protein, ether extract, ash and nitrogen free extract contents for breast and thigh muscles. Cost-return analysis revealed significant (p<0.05) differences in total variable cost, total revenue, gross margin and returns on investment. In conclusion, 3% blood meal with up to 0.5% methionine fortification can favourably replace 3% fish meal as an animal protein source for broilers.

“…Kidd et al [ 7 ] pointed out that healthy poultry responded positively to the inclusion of amino acids as feed additives and had an affirmative impact on performance. Methionine supplementation can alter the immune response and is beneficial in reducing immunologic stress [ 8 ]. The addition of methionine boosted the reproduction performance, egg quality and egg production of broiler breeders [ 9 , 10 ].…”

The present study was carried out to study the effects of varying dietary DL-methionine (0, 0.5, 1.5, 2.5, and 3.5 g/kg) levels on the productive and reproductive performance, egg quality and blood biochemical parameters of quail breeders. In total, 150 mature Japanese quails at eight weeks of age were randomly allotted to five groups of 30 for each group. Each group included five replicates, each of six quails (four females and two males). The results showed that egg number, egg weight and egg mass were higher (p < 0.05) with the addition of all DL-methionine levels than that of the control group. Quails from the control group had a lower feed intake (p < 0.001) and a worse feed conversion ratio (FCR) than those from the DL-methionine-treated groups. Supplementation of DL-methionine up to 2.5 g/kg in quail diets increased fertility and hatchability percentages. Birds fed DL-methionine at 1.5 g/kg had the best egg production indices, better FCR and the highest values of fertility and hatchability. Egg weight, yolk %, Haugh unit, egg shape index and unit surface shell weight (USSW) were increased and eggshell % was decreased in quail supplemented with DL-methionine levels compared with the control quail (p < 0.05). Dietary DL-methionine levels did not affect (p > 0.05) the hemoglobin (Hb), red blood cells (RBCs), white blood cells (WBCs) and packed cell volume (PCV) of quails. DL-methionine levels (0.5 and 2.5 g/kg) augmented lymphocytes and basophile (p < 0.05). Low DL-methionine levels (0.5 or 1.5 g/kg) improved liver enzymes and kidney functions. Dietary DL-methionine levels (except 3.5 g/kg) declined serum lactate dehydrogenase (LDH) and decreased lipid profile parameters (except high-density lipoprotein—HDL). Supplementation of DL-methionine at 0.5 and 1.5 g/kg increased immunoglobulin (IgG, IgM and IgA) and superoxide dismutase (SOD), total antioxidant capacity (TAC), catalase (CAT) and reduced glutathione (GSH) (p < 0.001) compared with the control. In conclusion, dietary supplementation of DL-methionine (1.5 g/kg) can enhance the reproductive performance and egg quality of quail breeders. DL-methionine use at levels of 0.5 or 1.5 g/kg improved the liver and kidney functions, lipid profile, immunity and antioxidant parameters of Japanese quail.
