The Effects of Probiotic and Mannanoligosaccharide on some Haematological and Immunological Parameters in Turkeys

Abstract

The study was conducted to investigate the effects of mannanoligosaccharide (MOS) and probiotic supplementation on haematological and immunological parameters in turkeys. A total of 72, 15-day-old white hybrid converter turkey poults were used in this study. Poults were assigned into three groups, each group consisted of six poults and the trial was repeated four times. The control group was fed a basal diet without supplemented probiotic and MOS, and treatment groups were fed either 1 g/kg MOS or probiotic added diets. At the end of the 15-week treatment period, samples of blood were collected to determine immunological and haematological values. The comparison among the groups showed that both the probiotic and MOS supplementation resulted in significant increases (P < 0.05) in the serum IgG and IgM levels, and significant decreases (P < 0.05) in the peripheral blood T lymphocyte percentage compared with those of the control group. Mean serum IgG level (7.06 g/l) was significantly higher (P < 0.05) in poults supplemented with probiotic compared with MOS (6.76 g/l). It was observed that the probiotic supplementation caused statistically significant increases (P < 0.05) in the erythrocyte count, haemoglobin concentration and haematocrit values, but MOS supplementation did not have a significant effect (P > 0.05) on these parameters. Total leucocyte and differential leucocyte counts were not affected by dietary MOS and probiotic supplementation. These results show that MOS or probiotic may elevate IgG and IgM levels in turkey. The MOS and probiotic that enhance immunoglobulin levels will have a more positive effect on growth performance, production and turkeys' ability to resist disease.

Effect of Dietary Prebiotic Mannan Oligosaccharide (MOS) on Growth Performance, Intestinal Microflora, Body Composition, Haematological and Blood Serum Biochemical Parameters of Rainbow Trout (Oncorhynchus mykiss) Juveniles

“…In the digestive tract, MOS prevent attachment and colonization of pathogenic bacteria and reduce adverse effects of microflora metabolites. Mannan oligosaccharide may also enhance health by stimulating antibody production (Cetin et al, 2005). The results of the current study showed that the highest growth performance and feeding parameters including final weight, body weight increase, specific growth rate and feed conversion ratio were observed in 1.0 g MOS kgG 1 (p<0.05).…”

Effect of Supplementation of Various Levels of Inulin on Growth Performance, Carcass Characteristics and Survivability in Raja II Broilers

“…Cetein et al, (2005) concluded that increase in body weight in birds was due to immunologic competence of prebiotics and its effect of increasing the active antibacterial substance.…”

Níveis crescentes de parede de levedura sobre a resposta imune celular e perfil hematológico de frangos de corte

“…Os componentes da parede de levedura, os mananoligossacarídeos e os ß-glucanos têm sido considerados como importantes agentes na modulação da resposta imune em perus (Cetin et al 2005) e em frangos (Shashidhara & Devegowda 2003, Lowry et al 2005. Sob o aspecto reação inflamatória e inativação de bactérias, Lowry et al (2005) observaram uma melhor atividade fagocítica e de destruição bacteriana, por heterófilos isolados de aves que receberam uma dieta contendo ß-glucanos purificados.…”

“…Os parâmetros afetados (P≤0,05) foram os nú-meros de eritrócitos (Y=2,5232-0,1022PL+0,0289PL 2 ), a hemoglobina (Y=12,3170-0,4209PL+0,1254PL 2 ) e o hematócrito (Y=33,3989-1,4249PL+0,4225PL 2 ), com pontos de mínimo com suplementação de 1,77kg, 1,68kg e 1,69kg de parede de levedura/tonelada respectivamente. Os resultados encontrados divergem dos observados por Cetin et al (2005) que verificaram que aves que receberam suplementação de 1g de MOS/kg de ração não apresentaram alterações no perfil eritrocitário.…”

“…No leucograma, o resultado obtido encontra-se em acordo com Cetin et al (2005), em que a contagem de leucócitos totais e a contagem diferencial não foram afetadas (P>0,05) pela suplementação proposta, nem em níveis superiores, ou seja, os mananoligossacarídeos e/ ou os ß-glucanos, não melhoraram, em números absolutos, e sem ocorrência de quadro clínico, uma das primeiras linhas de defesa das aves, os heterófilos. A mesma consideração pode ser feita para os linfócitos circulantes.…”
