A total number of 250 commercial broiler chicks were randomly assigned to five dietary treatments (commercial basal diet as control; commercial basal diet supplemented with 0.2% MOL; 0.2% MOL+200 mg/kg vitamin E; 0.2% MOL+200 mg/kg vitamin C and 0.2% MOL+0.35 g/kg organic zinc). Results showed that adding MOL with vitamin E, vitamin C or zinc significantly (p<0.05) increased body weight gain as compared with the control and MOL. Feed conversion ratio was significantly improved with all treatment groups compared with the control. All dietary supplements significantly improved hemoglobin concentration, heterophils to lymphocytes ratio, plasma total protein, albumin and globulin levels. Aspartate aminotransferase decreased significantly while, alanine aminotransferase did not affected by...

The nutrients contents and the digestibility coefficients for DDGs were estimated using male rabbits ''California x Newzeland'' six months old. Thirty six male rabbits of six- weeks -old were used to determine the influence of feeding different levels of DDGs to growing fattening California x Newzeland rabbits on the productive traits. Treatments consisted of mixed diets containing 0, 10, 20 or 30% DDGs. The diets were iso-nitrogenous and iso-caloric (16.5% crude protein and 2620 kcal DE/kg diet). The nutrients content of DDGs under investigation showed the values of 25.2% CP, 7.6% CF, 16.6% EE, 38% NFE and 6.2% ash. Amino acids profile showed that lysine is the lowest amino acid in this DDGs sample comparing to soybean meal amino acids profile. The estimated digestibility coefficients as being d...

The chemical analysis included proximate analysis and essential amino acids content. The chemical score (CS) and essential amino acids index (EAAI) values were calculated for the amino acids pattern.

Starter, grower and finisher diets were ® supplemented with two levels of both being 0 and 150 g tG artichoke extract and 0 and 600 g tG 1 1

Carcass characteristics, histological changes of ileum and immune related organs (bursa, thymus and spleen) along with intestinal bacteria count were also studied. A number of 150 Cobb broiler chicks were fed on three dietary treatments: a basal cornsoybean meal diet served as a control treatment with no supplements or supplemented with either 0.025% Bacitracin Methylene Disalicylat (BMD, antibiotic) or 0.06% Galliacid® (organic acids) from 10 to 36 days of age. The results showed that birds fed antibiotic or organic acids gained significant (p<0.05) more body weight than those fed the control diet. No significant differences were detected among treatments on feed intake while feed conversion ratio values were significantly (p<0.0001) differ. Addition of organic acids or antibiotic did improve FCR by about 9 and 2%, respectively. These results indicated that birds fed either organic acids or antibiotic supplemented diets utilized feed more efficiently than those fed the control diet. Carcass characteristics were not affected by dietary treatments, while the addition of antibiotic or organic acids significantly (p<0.01) increased spleen and bursa weight (% live body weight). Addition of organic acids was more effective than antibiotic on decreasing intestinal count of Escherichia coli and appearance of Colostridium perfringers. Organic acids as alternative to the antibiotic growth promoter have stimulated some histological change in histology of the villi and the immune related organs. Performance and feed efficiency are closely interrelated with the quantitative microbial load of the gut, the morphological structure of the intestinal wall and the activity of the immune system. In conclusion, dietary inclusion of organic acids increased growth performance and improved intestinal health and morphology of broiler chicks. It could be successfully used as alternative to antibiotic growth promoters in broiler diets or as a tool of controlling intestinal pathogenic bacteria.
