“…On the contrary, MCFA (especially lauric acid; C12:0) were found to increase IL-1α expression in vitro in a dose response manner through toll-like receptor (TRL-4) activation (Lee et al, 2001). Although effects of nutrition on immune function in poultry have been extensively reviewed (Korver, 2012), most studies do not focus on effects of nutrition in the 1st week after hatch. Moreover, mostly general effects of feed and water access on immune function and function are studied, ignoring effects of diet composition (Walstra, 2011;Simon et al, 2014).…”

Delayed feed and water access is known to impair growth performance of day old broiler chickens. Although effects of feed access on growth performance and immune function of broilers have been examined before, effects of dietary composition and its potential interaction with feed access are hardly investigated. This experiment aimed to determine whether moment of first feed and water access after hatch and pre-starter composition (0 to 7 days) affect growth rate and humoral immune function in broiler chickens. Direct fed chickens received feed and water directly after placement in the grow-out facility, whilst delayed fed chickens only after 48 h. Direct and delayed fed chickens received a control pre-starter diet, or a diet containing medium chain fatty acids (MCFA) or fish oil. At 21 days, chickens were immunized by injection of sheep red blood cells. The mortality rate depended on an interaction between feed access and pre-starter composition ( P = 0.014). Chickens with direct feed access fed the control pre-starter diet had a higher risk for mortality than chickens with delayed feed access fed the control pre-starter diet (16.4% v. 4.2%) whereas the other treatment groups were in-between. BW gain and feed intake till 25 days in direct fed chickens were higher compared with delayed fed chickens, whilst gain to feed ratio was lower. Within the direct fed chickens, the control prestarter diet resulted in the highest BW at 28 days and the MCFA pre-starter diet the lowest (Δ = 2.4%), whereas this was opposite for delayed fed chickens (Δ = 3.0%; P = 0.033). Provision of MCFA resulted in a 4.6% higher BW gain and a higher gain to feed ratio compared with other pre-starter diets, but only during the period it was provided (2 to 7 days). Minor treatment effects were found for humoral immune response by measuring immunoglobulins, agglutination titers, interferon gamma (IFN-γ), and complement activity. Concluding, current inclusion levels of fish oil (5 g/kg) and MCFA (30 g/kg) in the pre-starter diet appear to have limited (carryover) effects on growth and development, as well as on humoral immune function.

“…Innate immune response is the first to recognize the generic patterns of antigens and it continues until the homeostasis is restored. When the innate response is not able to tackle the imbalance caused by the antigen, the adaptive immune response is initiated and the immunity generated by it confers a memory for this particular antigen (Korver, 2012). It is difficult to understand how the receptors and components of the immune system interact to modulate the immune response against stress.…”

ABSTRACT. Poultry production is faced with different types of stresses that are responsible for issues of animal welfare as well as for economic losses. Moreover, the immunity decreases when animals are stressed. In silico analyses are important in reducing the cost and in increasing the accuracy of scientific results. A bioinformatics tool was used to perform ontology studies on 15 different immunological sequences of poultry. The mRNA structures and sequences with maximum antigenic residues were also predicted. No homology was found between the sequences of poultry and mammals. These results helped in the prediction of new potential molecular markers. Of the 15 sequences that were analyzed, predictions could not be made for five because they were longer than 2500 nucleotides; for the remaining 10 sequences, 20 conformational 2 L.J. Lara et al. Genetics and Molecular Research 16 (2): gmr16029423structures per sequence were predicted and the most stable sequences were identified by their minimum free energy values. The highest antigenic epitopes were accepted by the maximum scores; 15 of the total 8934 epitopes that were predicted were analyzed. These results would aid future studies that use synthetic peptides or recombinants as markers or immunomodulators and would expand our understanding on how stress can modulate the immune system. These would also help in developing rapid diagnostic tools, in increasing animal welfare, biosecurity, and productivity, and also in developing of food additives and environmental enrichment for stress control, thereby, making animal production more sustainable.
