“…These results disagree with those reported by Cera et al (1988), Makkink et al (1994), McCracken et al (1999 and Klurfeld (2002), who demonstrated a significant effect of total nutrient intake on gastrointestinal tract development; VH was directly related to dry matter and energy intake.…”

“…However, important changes in the composition of the diet occur at weaning and require the presence of appropriate enzymes in the stomach, pancreas and intestine, which are usually not produced during the suckling period. As a consequence, weaning is associated with physiological and nutritional stress, which reduces feed intake and weight gain (Makkink et al, 1994).…”

-The objective of this study was to evaluate the effect of diets supplemented with plasma and/or yeast extract on performance (daily weight gain [DWG], daily feed intake [DFI] and feed conversion [FC]) and intestinal morphology of piglets from 7 to 63 days of age. A total of 288 piglets aged 7 days and weighing 2.57±0.05 kg were studied. A randomized block design consisting of four experimental diets, six repetitions and 12 piglets per experimental unit was adopted. The prestarter I (7 to 21 days), pre-starter II (22 to 35 days) and starter I (36 to 49 days) diets were supplemented as follows: control diet (CD): no plasma or yeast extract; plasma (PL) diet: addition of 6%, 4% and 2% plasma; yeast extract (YE) diet: addition of 6%, 4% and 2% yeast extract; plasma + yeast extract (PL+YE) diet: addition of 3%, 2% and 1% plasma and yeast extract each. From 50 to 63 days of age all piglets received the same diet. No difference in performance was observed from 7 to 21 days and from 7 to 28 days of age, whereas DWG was higher from 7 to 35 days in piglets receiving the PL+YE diet (268, 278, 271 and 288 g/day for CD, PL, YE and PL+YE, respectively). From 7 to 49 days and from 7 to 63 days, DWG (330 and 519 g/day, respectively) and DFI (307 and 647 g/day) were higher in animals receiving the PL-YE diet when compared with those consuming CD (DWG: 295 and 486 g/day; DFI: 266 and 594 g/day). No significant differences in intestinal morphology were observed between piglets receiving the different diets. The combination of plasma and yeast extract elevates DWG, but does not affect the intestinal morphology of piglets from 7 to 63 days of age.

“…Overall changes in digestive organ weights during the post-weaning period (trial 1) and with changing energy intake (trial 2) were similar to those reported earlier [10,34]. The about 20% decrease in the relative weights of the large and small intestines observed in trial 1 was consistent with values ranging from 18 to 34% found in piglets weaned at later ages [5,7,19,20,26,36]. Furthermore, the mucosa was the most affected SI component, being reduced by 55%.…”

Small intestine growth and morphometry in piglets weaned at 7 days of age. Effects of level of energy intake

et al. 2002

View full text Add to dashboard Cite

-Two trials involving a total of 56 pigs were conducted to examine the effects of weaning at 7 d of age (trial 1) and of energy intake level and length of post-weaning underfeeding period (trial 2) on small intestinal (SI) development and morphometry. At 3 d after weaning, weight of the SI and mucosa (g/kg body weight) and villous height along SI were reduced by 20, 36 and 41%, respectively, compared to the day of weaning. Intestinal morphometrical changes are dependent on SI site and days post-weaning. Villous atrophy on d 3 and recovery on d 14 post-weaning were greater and occurred earlier in the proximal than in the medial and distal SI. Villous height was dependent on the level of energy intake which explains 56% of the variations in proximal SI villous height in weaned pigs and 73% when data of the sow-reared pigs were included in the analysis. Moreover, after 4 d of refeeding, underfed piglets showed similar villous characteristics to piglets fed a continuously high feeding level after weaning stressing that capacities of intestinal restoration were not affected by the length of the post-weaning underfeeding period. Overall, the present results suggest a spatial and temporal effect of weaning on villous atrophy and recovery, and that the level of energy intake is a major factor accounting for the post-weaning villous height.weaning / level of food intake / small intestine / morphometry / piglet Reprod.

“…No entanto, Makkink et al (1994), em experimento com leitões desmamados aos 28 dias de idade e alimentados com leite em pó desnatado e concentrado protéico de soja, obtiveram peso de pâncreas superior ao dos alimentados com farelo de soja, portanto, a proteína de soja processada apresenta bons resultados de desenvolvimento pancreático nesta fase. O mesmo foi demonstrado com a inclusão de isolado protéico de soja, que não alterou o desenvolvimento pancreático.…”

RESUMO -Um experimento foi conduzido para comparar diversos níveis e fontes protéicas utilizados em rações sobre o desempenho, a morfometria intestinal e a relação peso de pâncreas/peso de carcaça de leitões de 36 a 70 dias de idade. Foram utilizados 96 leitões desmamados distribuídos em delineamento de blocos ao acaso com seis tratamentos e quatro repetições de quatro animais. Avaliaram-se seis fontes protéicas (tratamentos): leite em pó desnatado (8,80 e 12,00%); isolado protéico de soja (3,20 e 4,50%); farinha de peixe (5,00%); e levedura seca (10,00%). As dietas, isoenergéticas e isoprotéicas, não afetaram o ganho de peso e a conversão alimentar dos animais, contudo, os animais que receberam a dieta contendo leite em pó desnatado apresentaram maior consumo no período de 56 a 63 dias de idade. Não houve efeito significativo das fontes protéicas sobre a altura de vilos, a profundidade de cripta e a relação peso do pâncreas/peso corporal. As fontes protéicas estudadas e os níveis utilizados nas dietas não influenciaram o desempenho, a morfologia intestinal e a relação peso de pâncreas/ peso de carcaça em leitões de 36 a 70 dias de idade.Palavras-chave: desempenho, farinha de peixe, isolado protéico de soja, leite em pó desnatado, levedura seca, morfologia intestinal Evaluation of levels and protein sources in diets of piglets in the initial growth phaseABSTRACT -An experiment was conducted to compare different levels and sources of protein on performance, intestinal morphology and pancreas weight/carcass weight ratio in the diets of piglets from 36 to 70 days old. A total of 96 piglets was allotted to a randomized experimental block design in six diets, with different levels and protein sources, four replicates of four animals per experimental unit. The levels and the protein sources evaluated were: dry skim milk (8.80 and 12.00%), isolated soybean protein (3.20 and 4.50%), fish meal (5.00%) and dry yeast (10.00%). The diets were isoenergetics and isoproteics. The diets did not affect weight gain and feed conversion of the animals, however, the pigs that were fed diet with dry skim milk showed higher feed intake from 56 to 63 days old. There was no effect of protein sources on villus height, crypt depth and pancreas weight/carcass weight ratio. The levels and protein sources in the diet did not affect performance, intestinal morphology and pancreas weight/carcass ratio of the piglets from 36 to 70 days old.Key Words: dry skim milk, dry yeast, fish meal, intestinal morphology, isolated soybean protein, performance IntroduçãoAtualmente a tecnologia empregada na produção de suínos visa diminuir a idade de desmame a fim de aumentar a produtividade das porcas, o que resulta em aumento de leitões produzidos por porca/ano. O êxito desta prática requer, no entanto, a utilização de dietas diferenciadas, contendo ingredientes com alta digestibilidade para esse período tão crítico da vida do leitão, uma vez que o acúmulo de situações estressantes é inevitável e deixa o animal suscetível a distúrbios gastroentéricos.Visand...
