“…The results indicated that depression of dietary CP level from 18% to 14% gave harmful effects on the secondary lymphoid tissue. These phenomena were confirmed by Payne et al. (1990) and Kenney et al.…”

The objective of this study was to determine the effect of protein levels on production performance, immune response, liver triglyceride and plasma amino acids profile of laying hens during 21-48 weeks of age. Two groups of commercial hens (Babcock B-308) were fed with diets with different crude protein levels (14% and 18% CP). The high protein diet (18% CP) significantly increased production performance, essential amino acid intake, spleen weight (% of body weight), ND-titre (haemagglutination-inhibition test), serum albumin (g/dl), serum alpha-globulin and plasma essential amino acids (except histidine) and decreased liver triglyceride (mg/g liver) in relation to the low protein diet (14% CP). In long-term effect, therefore, this study suggested that adequate dietary condition of amino acids, particularly methionine and branch-chain amino acids is necessary for sustaining normal immunocompetence and achieving maximum production performance.

“…ND‐titre of hens fed 18% CP diet was significantly higher than that of hens fed 14% CP. Accordingly, Payne et al. (1990) reported that susceptibility to Newcastle disease virus was increased dramatically in protein‐deprived chicks and serum antiviral antibody responses were also reduced.…”

“…However, significant effects of dietary protein and amino acids levels on bird immunity have been reported (Kidd, 2004). Payne et al (1990) reported that the feeding with very low protein diets had negative effects on cellular immunity of birds. Significant interactions between additives and protein levels were not observed for antibody response to Newcastle disease.…”

In order to investigate the effects of the dietary supplementation of organic acids, prebiotics and probiotics on broiler chickens, a total of 288 day-old male Cobb chicks were allocated in a completely randomized design according to a 2 × 4 factorial, consisting of two levels of crude protein (recommended or low (85% of recommended)) and a four feed-additive programme. The basal diet without any feed additive served as control and one of the following additives, organic acids, a prebiotic and a probiotic, were added to the basal diet to form the other treatments. Starter and finisher diets were offered from 1 to 21 d and 22 to 42 d of age, respectively. The birds were reared in an open-sided house system under natural tropical conditions with the same housing and general management practices. Lowering the dietary protein level significantly decreased bird performance throughout the experiment. Additives had no significant effects on body weight, body weight gain and feed intake. Dietary supplementation with the prebiotic resulted in significant improvements in feed efficiency during 22 -42 d and 1 -42 d of age. At 21 and 42 d of age birds fed the diets containing the prebiotic had the longest duodenal villi compared to the other treatments. Jejunum villi, and duodenum and jejunum crypt depth were not influenced by additives. At 21 d of age the dietary addition of the prebiotic and organic acids significantly increased the antibody titres against Newcastle disease compared to the control group. It could be concluded that under the condition of the current study, the prebiotic affected performance, small intestinal morphology and immunity of broiler chickens significantly. ______________________________________________________________________________

“…It has been demonstrated that deficiency or excess of dietary protein (Glick et al, 1981(Glick et al, , 1983Payne et al, 1990) or amino acids (Bhargava et al, 1970(Bhargava et al, , 1971Tsiagbe et al, 1987aTsiagbe et al, , 1987b) alters immune responses. BCAA have been shown to play very important roles in the immune organ development (Kidd, 2004).…”

A 9-week feeding trial was conducted in low temperature season to evaluate the effects of varying levels of dietary isoleucine on hematology and innate immune response of juvenile olive flounder. Six isonitrogenous (45% crude protein) and isocaloric (4.45 kcal g -1 gross energy) diets containing graded levels of isoleucine (0.48, 0.87, 1.43, 1.94, 2.37 and 2.78% dry diet) were formulated. Triplicate groups of fish (8.59 ± 0.13 g) were fed the six test diets to apparent satiation twice daily. Fish growth performance was affected by dietary isoleucine levels and the highest growth was obtained at 1.43% isoleucine. The results showed the significant (P<0.05) increase of plasma total protein and cholesterol concentrations at isoleucine levels of 1.43 -2.37% compared to those offered 0.48% isoleucine. Also, significant reductions in plasma alanine aminotransferase and aspartate aminotransferase activities were detected by increment of dietary isoleucine up to 1.94%. Fish innate immunity was significantly affected by isoleucine levels. Significantly higher lysozyme activity was found at 0.87 -2.37% isoleucine and superoxide dismutase activity increased at 1.94-2.37% isoleucine levels. Respiratory burst activity and total immunoglobulin level were significantly enhanced at isoleucine levels of 1.43-1.94 and 1.94%, respectively. The findings in this study showed that inclusion of approximately 2% isoleucine in diets for olive flounder can enhance innate immunity. To estimate isoleucine requirement of the species further studies are required.
