“…Similar to the current study, earlier researchers also demonstrated a non‐significant difference in terms of feed consumption due to methionine supplementation of broiler diets . Improvement in feed conversion due to supplementation of methionine was in line with previous findings . Data indicate the highest values for weight gain and the lowest values for FCR in birds fed diets containing DLM + MM, from which it may be speculated that there is a synergism between DLM and MM due to better utilization of available methionine from feed ingredients as well as from DLM .…”

“…In a recent study, Kalbande et al reported increased live weight of broilers fed a herbal methionine‐supplemented diet compared with untreated control. They demonstrated an observed increase in weight gain of broilers due to the composition of the herbal methionine preparation, in which different herbs may have the ability to supply bioavailable methionine to support production performance . Conversion of different natural compounds to methionine and efficient recycling may be additional reasons for the observed improvement …”

“…Thus the use of compounds sparing DLM and MHA in vivo may be advantageous in reducing homocysteine production and improving poultry health and nutrition . Several studies have reported methionine‐sparing effects of various micronutrients such as betaine, choline and other natural bioactive compounds . Ribeiro et al revealed the ability of broilers to utilize different forms and sources of methionine without compromising production performance …”

“…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.

“…Synthetic methionine is expensive and its use in organic poultry feed production is limited. [33] Therefore, a natural alternative needs to be found for methionine supplementation in poultry feed. Methionine over-producing microorganisms may be an inexpensive source of natural methionine for the poultry industry.…”

Methionine is one of the first limiting amino acids in poultry nutrition. The use of methionine-rich natural feed ingredients, such as soybean meal or rapeseed meal may lead to negative environmental consequences. Amino acid supplementation leads to reduced use of protein-rich ingredients. The objectives of this study were isolation of potentially high content methionine-containing yeasts, quantification of methionine content in yeasts and their respective growth response to methionine analogs. Minimal medium was used as the selection medium and the isolation medium of methionine-producing yeasts from yeast collection and environmental samples, respectively. Two yeasts previously collected along with six additional strains isolated from Caucasian kefir grains, air-trapped, cantaloupe, and three soil samples could grow on minimal medium. Only two of the newly isolated strains, K1 and C1, grew in minimal medium supplied with either methionine analogs ethionine or norleucine at 0.5% (w/v). Based on large subunit rRNA sequences, these isolated strains were identified as Pichia udriavzevii/Issatchenkia orientalis. P. kudriavzevii/I. orentalis is a generally recognized as a safe organism. In addition, methionine produced by K1 and C1 yeast hydrolysate yielded 1.3 ± 0.01 and 1.1 ± 0.01 mg g(-1) dry cell. Yeast strain K1 may be suitable as a potential source of methionine for dietary supplements in organic poultry feed but may require growth conditions to further increase their methionine content.
