The Impact of Effective Microorganisms (EM) on Egg Quality and Laying Performance of Chickens

Abstract

Chickens kept under modern production system are very small and contribute less than 2% of eggs and meat production in Ethiopia. In some parts of the country, effective microorganism (EM) has been used as a means of improving egg and meat production. However, there is information gap on the use and effect of EM on egg quality and laying performance of chickens in the local context. This study was conducted in Aksum University’s poultry farm located at the main campus in Axum, to evaluate egg laying performance and quality of eggs in layer chickens treated with effective microorganisms in feed and water. In this experiment, 180 pullets of ISA Brown chickens with uniform age and weight were used and managed in a cage system. Chickens were subjected to 4 treatments with 3 replications, and each replication consisted of 15 chickens. Data collection was started at the first egg lay. Data including feed intake, conversion ratio, and age at first laying, laying percentage, and egg quality parameters were collected. Statistical analysis was carried out using JMP. Chickens fed with EM in feed and drinking water had higher egg production percentage. There was a significant difference in egg laying percentage between the treated and control groups ( P < 0.001 ). Eggs from chickens given EM in feed and water were 6% heavier in weight than those from control birds. Lower feed daily intake (115.5 gram) and feed conversion rate (2.05) were achieved in chickens treated with EM in feed and water. Significant improvement on egg quality was revealed in chickens that received EM in feed and water. From this experiment, it can be concluded that the use of EM in feed and water improves egg production in layer chickens and therefore recommended for medium-scale poultry farms in Northern Ethiopia.

Performances and adaptability of two upgraded dwarf layers under smallholder farmers’ condition

“…Weight at sexual maturity was found to be lower among the IDC♂ × Fay♀ (1101.5 g) when compared to the IDC♂ × WLH♀ pullets (1153.3 g) which is in agreement with the findings of Yeasmin (2001). Weight of the first egg laid (28.17 g) and average egg weight (40.92 g) were also lower among the IDC♂ × Fay♀ pullets which is in close accordance with the findings of Padhi et al (2016), Atsbeha and Hailu (2021) and Khawaja et al (2012). However, egg mass was higher among the IDC♂ × Fay♀ pullets (25.07 g/bird/day) when compared to the IDC♂ × WLH♀ counterparts (21.71 g/bird/day).…”

Natural Products of Plants and Animal Origin Improve Albumen Quality of Chicken Eggs

“…Albumen nitrogen (94) and crude protein content (90) was increased in laying hens fed Saccharomyces fermented product and C. butyricum, respectively. In a likely manner like other probiotics, effective microorganisms (EM), a natural product consisting of various microbes (photosynthetic bacteria, actinomycetes, yeast, Lactobacillus) (95), enhanced albumen height and HU values (96). The improvement in albumen quality due to dietary probiotics may be associated with influence of probiotics on animal health and physiological status.…”

Effect of Berberine on Some Histopathological, Enrofloxacin Residue and Aniti-Diarrheaginic Escherichia coli in Broilar Chicken

“…P oultry chickens are commercially breed for egg and meat production because they grow quickly and are fairly inexpensive (Atsbeha and Hailu, 2021). In fact, the demand for meat is rising day by day, as various drugs have been used to promote growth and control infection.…”
