The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

This investigation evaluated, in broiler chickensPectoralisandGastrocnemiusmuscles, the effect of the dietary supplementation with sodium selenite (0.3 ppm) versus selenomethionine (0.3 ppm), on the fatty acids composition, lipids indices, and enzymes indexes for desaturase, elongase, and thioesterase. The selenium reduced, in both muscles, the content of atherogenic fatty acids, C14:0 and C16:0, while it increased the C18:1 level. On the other hand, selenium increased, in both muscles, the content of C18:3n3 and EPA, but not DPA and DHA. No selenium effect was detected for PUFA/SFA, n-6, n-3, n-6/n-3, and atherogenic and thrombogenic indices. As for the enzyme indexes, a selenium effect is only detected for thioesterase. Taken together, the results highlight the potential effect of dietary selenium, mainly selenomethionine, in the modulation of the composition of fatty acids in chicken meat, in particular, reducing the content of atherogenic fatty acids and increasing the health promoting n-3 PUFA.

ABSTRACT The effect of dietary fat source (soy oil or a mixture of lard and tallow) and dietary supplementation with antibiotics (a combination of avilamycin at 10 mg kg of feed−1 and salinomycin at 40 mg kg of feed−1) on the bacterial community in the ileum of broiler chickens at different ages (7, 14, 21, and 35 days) was studied using PCR with denaturing gradient gel electrophoresis (DGGE) analysis and bacteriological culture. The bacterial origin of fragments in DGGE profiles was identified by sequencing. Bacterial enumeration results, together with PCR-DGGE profiles, showed that the composition of the microflora was age dependent and influenced by dietary fat source and antibiotic supplementation. An increased incidence of streptococci, enterobacteria, and Clostridium perfringens with age of the chickens was demonstrated. Lactobacilli and C. perfringens were the bacterial groups most strongly affected by the dietary treatments. Moreover, different strains (clonal variants of the alpha-toxin gene) of C. perfringens type A were detected in response to age, dietary fat source, and dietary supplementation with antibiotics.

Main Effects

A factorial experiment with 1440 day-old Hubbard chicks was conducted to assess the interacting effects of dietary Na, K, Cl and Ca on general performance and incidence of leg abnormalities, especially tibial dyschondroplasia (TD). For Ca at 0.95%, all combinations of Na (0.17, 0.30), K (0.80, 1.10, 1.40), Cl (0.22, 0.44) were present; for Ca at 1.38% the combinations were the same except for K (0.80, 1.40). The various cation combinations produced 12 and 8 different meq kg−1 of (Na + K − Cl) for Ca at 0.95 and 1.38%, respectively. Body weight gain and feed conversion were affected by the main effects K, Ca and Na and also by their interaction. Both weight gain and efficiency of feed utilization were influenced by cation-anion balance as shown by significant Ca × K, Na × K, Ca × Na (feed conversion only) and K × Cl interactions. Increasing dietary K or Na increased litter moisture, whereas Cl moderated the effect of Ca. The incidence of TD was reduced by increasing dietary Ca, Na or K but their effects are interdependent on each other and on the level of dietary Cl as evidenced by significant Ca × Na, Na × K and Na × K × Cl interactions. Feeding diets with (Na + K − Cl) between 155 and 300 meq kg−1 had little effect on growth and feed conversion. Dietary Ca level changed both the pattern and response of birds for growth and feed utilization, suggesting that the term meq kg−1 (Na + K − Cl) is an inadequate measure of dietary cation-anion balance.

Gait Score

The aim of this study was to survey and report the walking ability in broilers housed in both conventional and organic production systems in Denmark. To this end, the authors assessed the walking ability, by using the Bristol scale, in 31 conventional broiler flocks and in 29 organic broiler flocks distributed across Denmark. In addition, assessment of contact dermatitis, leg abnormalities, scratches and plumage cleanliness, as well as postmortem analysis of tibial dyschondroplasia, was performed in conventional broilers. The survey found a prevalence of 77.4 per cent of impaired walking ability (gait score (GS) >0) in conventional broilers and 38.1 per cent in organic broilers. The prevalence of severe lameness (GS >2) was 5.5 per cent and 2.5 per cent for conventional and organic broilers, respectively. The prevalence of tibial dyschondroplasia in conventional broilers was 4.7 per cent. The results on other welfare indicators are also presented for conventional broilers. The results from the present and previous surveys indicate that the prevalence of impaired walking ability in broiler chickens in the Danish conventional production system is high, but the severity has been steadily decreasing over the last 19 years. Furthermore, the results from the survey of organic broilers suggest that lameness is less prevalent and severe in this system relative to conventional production.
