Abstrakt: This work was designed to evaluate the advantages of using multi-strain probiotics feed (Bacillus subtilis, Bacillus licheniformis and Clostridium butyricum) (PRO) and alpha-monolaurin (AML) on laying performance, criteria of egg quality, blood parameters, and yolk fatty acids' profile in laying hens. One hundred forty of Bovans brown laying hens at 45 weeks old (25 th week of egg production) were randomly allocated into four groups, with seven replicates of five birds each in a complete randomized design. The first group was fed a basal diet without feed additives (0 g/kg diet), and the second, third, and fourth groups received diets containing 1 g PRO, 1 g AML, and 1 g PRO + 1 g AML/kg diet, respectively. No significant impacts of PRO, AML, or their mixture on body weight (BW), body weight gain (BWG), feed intake (FI), or egg weight. Egg production, egg mass, and feed conversion ratio (FCR) were enhanced by 1 g PRO/kg and /or 1 g AML/kg supplementation in laying hen diets. Furthermore, egg shape index, eggshell thickness, and yolk color were statistically higher by PRO and AML supplementation at 55 weeks. However, oviduct, infundibulum, and uterus weights were significantly decreased by 1 g PRO or/and 1 g AML. Additionally, total cholesterol, triglycerides, low density lipoprotein (LDL), glucose, and glutamate pyruvate transaminase (GPT) levels were decreased by PRO and AML supplementation. In conclusion, it seems that dietary inclusion with 1 g PRO/kg, 1 g of AML/kg, and 1 g PRO + 1 g AML improved egg production, egg mass, FCR, and yolk fatty acids profile and lowered total cholesterol and malondialdehyde (MDA) contents in laying hens.
