Study on the nutritive value of dextrin as a carbohydrate source for pigs weaned at 21 days of age

Abstract: Two experiments were conducted to compare the nutritive value of dextrin to that of various carbohydrate sources and to determine the optimal incorporation ratio with lactose for pigs weaned at 21 days of age. In each experiment, eighty pigs (BW 6.43±0.18 kg in experiment 1 and 6.93±0.19 kg in 2) were used as an experimental unit and allotted to 20 groups (4 pigs/group, 5 groups/ treatment) using a completely randomized block design. Each group was assigned to one of 5 dietary treatments. Dextrin (control), ma… Show more

“…However, these carbohydrates induced higher feed intake and better growth performance than did starch. DM digestibility was neither affected by carbohydrate source (Lee et al 2000;Mavromichalis et al 2001) nor was decreased by the use of starch (Jin et al 1998). Veum & Mateo (1986) found similar growth performance for piglets weaned at 1 d of age and fed a liquid diet containing either 53 % glucose, lactose, sucrose, or maize starch.…”

“…Likewise, average daily gain and feed efficiency were not affected by the carbohydrate source in the diet. Earlier growth performance trials (Jin et al 1998;Lee et al 2000;Mavromichalis et al 2001) with piglets weaned at 3 weeks of age and fed ad libitum showed that dextrin, molasses, and mono-and disaccharides were utilised equally efficiently. However, these carbohydrates induced higher feed intake and better growth performance than did starch.…”

“…As respostas evidenciaram-se quando o desmame ocorreu entre 4,1 e 5,0 kg, ao se compararem àquelas obtidas com leitões que começa-ram a fase inicial entre 5,5 e 6,8 ou 7,3 a 8,6 kg de peso. A altura das vilosidades e a profundidade das criptas de Lieberkühn são afetadas diretamente pela qualidade dos ingredientes da ração na fase pós-desmame e, principalmente, pela quantidade de ração consumida (Lee et al, 2000;Mavromichalis et al, 2001). Dunsford et al (1989) constataram que os melhores resultados para a digestibilidade dos nutrientes de rações contendo leite ou derivados lácteos devem-se ao equilíbrio da composição do leite pela presença da lactose e pelo perfil de aminoácidos em sua proteína.…”

“…Nesta fase, ocorre acentuada mudança na estrutura e função do intestino delgado, com redução da altura das vilosidades, do número de enterócitos maduros, da atividade de enzimas na borda em escova e aumento da profundidade das criptas (PLUSKE et al, 1996(PLUSKE et al, , 1997WU et al, 2004), reduzindo a capacidade digestiva e absortiva do intestino e o aproveitamento dos nutrientes da dieta. Estas modificações na estrutura do epitélio intestinal são afetadas diretamente pela qualidade dos ingredientes da ração, pela intolerância aos antígenos presentes nos ingredientes e pela quantidade de ração consumida (LEE et al, 2000;MAVROMICHALIS et al, 2001). Em condições de desmame precoce (21 dias de idade), o consumo voluntário de alimento pelo leitão lactente é baixo, não sendo suficiente para desenvolver adequada tolerância aos antígenos do alimento antes do desmame (LI et al, 1991), o que resulta em ativação imune e transformações da arquitetura do epitélio intestinal imediatamente pós-desmame.…”
