This experiment examined how adding mannan-oligosaccharides (MOS) to the diet affected fertility, hatching rates, egg production, carcass characteristics, cost-effectiveness, and immune function in laying hens. One hundred twenty Mandarah chickens (30 hens 3 roosters per group) were randomly chosen between 34 50 wk old divided into four groups. The first group was control group, which given just basal diet. second, third, fourth experimental groups along with three different levels of MOS (0.1, 0.2, 0.5 g/kg diet, respectively). Results found that fed at various laid eggs a significantly higher rate, enhanced number, mass feed conversion ratio than (

Abstract The use of organic acids as growth promoters in poultry diets continues to pique the researchers’ curiosity. So, this study aims investigate effect feeding formic acid, propionic or both their pure form on laying hens' productivity, egg quality, nutrient utilization, and some blood profiles during early production phase using eighty ISA Brown hens aged 28–42 weeks. were randomly assigned into four groups, each consisting 10 replicates with 2 hens/replicate. treatments C (control), F (1 ml acid/kg diet), P acid/kg), M (0.5 acid 0.5 acid/kg). percentage production, mass ( < 0.05), albumen crude protein percent, estradiol hormone 0.001) significantly increased upon acids’ mixture treatment, whereas percentages fat 0.05) yolk = 0.0006) decreased.

Background: This study was conducted to investigate the effects of different levels L-β-galactoglucan on growth performance, palatability, and health condition dogs. Methods: A total 32 healthy beagle dogs (2.0 ± 0.5 yr; 13.2 2.1 kg) were randomly assigned into four treatment groups, with 8 in each group. The fed basal diets supplemented 0 (control), 0.25, 0.5, or 1% L-β-galactoglucan. Results: results showed that feed intake ratio Low_Gal (0.25%) group significantly higher (p < 0.05) as compared control (Con) low-density lipoprotein cholesterol (LDL-C) Mid_Gal (0.5%) a trend toward lower = 0.069).
