“…The results of our study by using the product within the approved concentrations were consistent with the results of a local study (27) which indicated that the use of the product in drinking water for broiler and within the same concentration 1% had a positive effect on the immune response to the vaccination against Newcastle, where the researcher proved a significant increase in the titer of antibodies to the virus of Newcastle disease, also another study (11) indicated that the use of this product and by the same concentration in chicken via water or feed increases the level of immune response and activates the immune system as there was a significant increase in levels of IgG and IgM antibodies in general. Our results also agreed with the results of another local study (12), which used the product to improve food conversion and weight gain, they also used the product at 1% and noted that the use of the product and within this concentration had significant results in improving food conversion and weight gain and increasing the length of the villi in the jejunum and increasing the number of goblet cells. Also, a recent study (17) indicated that the use of this product with a concentration of 1% may be useful in anaerobic fermentation for the disposal of organic matter and waste.…”

“…The effective microorganisms have been used in many fields including agriculture and crop improvement, animal production especially fishes, poultry industry and increasing of food conversion, and wastewater treatment (10-18). As well as their using in soil dredging and improvement (26), and there are local studies have used effective micro-organisms to improve weight; average consumption of the feed and increase body immunity of broiler (12,27). So that the present study aimed to evaluate the efficacy of this product in inhibiting or reducing the growth of pathogenic bacteria.…”

This study was conducted to evaluate the efficacy of Effective Microorganisms (EM1 ® ) for inhibiting the growth of some pathogenic bacteria Staphylococcus aureus and E. coli were used in this study and isolated from pathological conditions. These bacteria were diagnosed in laboratory of microbiology, College of Veterinary Medicine, University of Mosul. The colonies that taken from blood agar were 5-7 and cultured in the nutrient broth and incubated at 37 ºC for 24 hours. Bacterial growth was calibrated with the second tube of the McFarland tubes 0.5%. Several concentrations of EM product were prepared 1, 0.5, 0.25 and 0.125%. Decimal dilutions were done for each concentration of EM product with bacterial suspension, except control group was done for bacterial suspension with nutrient broth. The bacterial count was done on nutrient agar, milk agar and EMB agar. The results of this study showed that the product of EM1 ® within concentrations 0.5-1% was highly efficient in inhibiting the growth of pathogenic bacteria under study. The bacterial count of both S. aureus and E. coli was 54x10 7 and 52x10 7 CFU/ ml respectively at 1% EM1 ® , and 67x10 7 and 86x10 7 CFU/ ml respectively at 0.5%, while the counting of the control group was 42x10 9 and 67x10 9 CFU/ ml respectively. This study concluded that EM1 ® at low concentrations have a clear role in inhibiting the growth of pathogenic bacteria, particularly S. aureus and E. coli.

“…Research has also been conducted for several years to determine the efficiency of effective microorganisms (EM) in broiler chicken production (Wondmeneh et al 2011;Jwher et al 2013). EM probiotics are a mixture of microorganisms (including bacteria, fermenting fungi, radiolaria) selected and formulated in the 1980s.…”

The objective of the study was to determine the effect of probiotic preparations Pro-Biotyk EM-15 and EMFarma™ and sex on morphometric characteristics of the digestive system and leg bones, and caecal microflora in Ross 308 broiler chickens. One-day chicks were distributed into two groups in two rooms (control, experimental). Each facility contained 9000 Ross 308 chicks and was divided into four compartments. A total of 48 Ross 308 broiler chickens aged 42 days were evaluated, including 12 males and 12 females which received no probiotics, and 12 males and 12 females supplemented with EM preparations. At the age of 42 days, EM supplemented broilers had significantly greater total intestine length, higher intestine-body length ratio and higher proventriculus percentage in body weight. Regardless of the treatment, males exhibited higher body weight, duodenum, jejunum, ileum lengths and total intestine length, higher intestine-body length ratio and spleen weight, and lower duodenum diameter and liver percentage. The group × sex interaction was significant for smallest breadth of the corpus of femur bone and greatest diagonal of proximal end, smallest breadth of the corpus and smallest breadth of distal end of tibia bone.

“…Over the last decade, effective microorganisms (EM) have become increasingly popular in agricultural practice. They were investigated in broiler chickens (Wondmeneh et al 2011;Jwher et al 2013), laying hens (Simeamelak et al 2013;Gnanadesigan et al 2014) and quails (Gesek et al 2018). Showing the positive effects of the EM probiotics in broiler chicken production with regard to meat quality may encourage an increase in the biologisation of modern agriculture.…”

The aim of the study was to determine the effects of probiotic preparations Pro-Biotyk Em-15 and EMFarma TM and sex on proximate chemical composition, physicochemical properties of breast and leg muscles, sensory properties (including texture) and microstructural characteristics of pectoralis major muscle in Ross 308 broiler chickens. The study used 48 carcases-12 from males and 12 from females fed no probiotics, and 12 from males and 12 from females receiving the EM probiotics. At 42 days, the chickens receiving EM preparations had significantly higher WB-shear force of pectoralis major muscle, whereas the leg muscles contained significantly less water and fat and had higher pH 24 value. Regardless of the treatment, males exhibited significantly higher springiness, chewiness, as well as significantly lower yellowness (b Ã), fibre perimeter, horizontal (H) fibre diameter and fibre cross section area of pectoralis major muscle when compared to females. In turn, male leg muscles had significantly higher fat content compared to female leg muscles. The genotype Â sex interaction was significant for the content of water, protein and fat, and for electric conductivity (EC 24) of leg muscles. HIGHLIGHTS Probiotics did not improve the quality of chicken meat. The influence of sex on the quality of chicken meat was varied.
