“…Nessmith et al (1996) também observaram desempenho similar em leitões alimentados com rações contendo 2,5 e 5,0% de plasma, respectivamente, quando utilizaram ração controle com 25,0% de soro de leite e 5,0% de lactose. Segundo Van Dijk et al (2001;, o efeito do plasma em melhorar o desempenho de leitões desmamados depende da qualidade da ração e é maior quando o plasma é incorporado em rações menos complexas ou de menor qualidade.…”

RESUMO -Avaliou-se o efeito da inclusão de glutamina, nucleotídeos e plasma suíno nas rações sobre o desempenho, a morfologia intestinal e a resposta imune de leitões desmamados aos 21 dias de idade. Utilizaram-se 252 leitões com peso inicial de 6,35 ± 0,80 kg, distribuídos em delineamento de blocos ao acaso, formados de acordo com o peso dos inicial dos animais, compondo sete tratamentos, seis repetições e seis animais por unidade experimental. Foram fornecidas uma ração controle e outras seis, formuladas com: glutamina (1,0%); ou um produto comercial de nucleotídeos; ou plasma suíno (2,0 ou 4,0%); ou plasma suíno (2,0%) + glutamina (1,0%); ou um produto comercial de nucleotídeos. As rações com plasma suíno proporcionaram os maiores ganhos de peso nos leitões aos 35 e 42 dias de idade. Os animais que receberam a ração controle apresentaram os piores resultados de ganho de peso. Nos primeiros 14 dias após o desmame, com exceção dos animais alimentados com a ração com nucleotídeos, todas as dietas com plasma proporcionaram maior consumo de ração. Os melhores resultados de ganho de peso diário foram obtidos com as rações com nucleotídeos, 2 e 4% de plasma, plasma+glutamina e plasma+nucleotídeos. A conversão alimentar dos animais não foi influenciada pelas rações experimentais nas duas primeiras semanas após o desmame. No período total (21 a 42 dias de idade), os melhores resultados de consumo e ganho de peso dos animais foram observados com o fornecimento das rações com 2% de plasma suíno e plasma + glutamina. Os animais da ração controle apresentaram o pior ganho de peso. Os animais alimentados com as rações com glutamina, 2% de plasma e plasma + nucleotídeos apresentaram a melhor conversão alimentar durante todo o período experimental estudado. A altura de vilosidades e a profundidade de criptas, assim como a população de leucócitos e linfócitos, não foram influenciadas pelas rações experimentais. A utilização de glutamina, plasma suíno e nucleotídeos na ração melhora o ganho de peso de leitões desmamados aos 21 dias de idade.

Two hundred and fifty two piglets, initial weight 6.35 ± 0.80 kg, were used placed in a randomized complete block deaign conducted in seven treatments, six replications and six animals per experimental unit. The initial weight of the animals was considered in the formation of the blocks. The treatments consisted of: the control diet, diet with 1.0% glutamine, diet with a commercial nucleotide product, diet with 2.0% swine plasma, diet with 4.0% swine plasma, diet with 2.0% swine plasma and 1.0% glutamine, diet with 2.0% swine plasma and commercial nucleotide product (PN). The diets with swine plasma gave the greatest weight gains to the piglets at 35 and 42 days o...

“…The period following weaning is usually characterized by low feed intake and poor weight gain (van Dijk et al, 2001) partly due to the sudden transition from a nutritious and readily digestible sow milk to dry feed. The poor performance associated with this period has been addressed by feeding diets containing high levels of crude protein (CP) supplemented with in-feed antibiotics as growth promoters.…”

A 21-day study was conducted to determine whether isoleucine might limit the performance of piglets fed low-crude protein (CP), amino acid (AA)-supplemented diets and to investigate the potential benefits of low-CP diets on gastrointestinal health in weaned pigs. Ninety-six piglets (initial BW 5 6.44 6 0.14 kg), housed four per pen, were randomly assigned to one of four diets, resulting in six replicate pens per diet. Dietary treatments were as follows: (1) 210 g/kg CP diet, (2) 190 g/kg CP diet deficient in isoleucine, (3) 190 g/kg CP diet supplemented with crystalline isoleucine up to the level in the 210 g/kg CP diet and (4) 170 g/kg CP diet supplemented with isoleucine and valine on the ideal protein ratio basis (60% and 70% relative to lysine, respectively). Pigs were allowed to adapt to the new environment for 4 days before the experiment commenced. Overall, pigs fed the 210 g/kg CP diet had higher (P , 0.05) average daily gain and lower (P , 0.05) feed : gain ratio compared with those fed the other diets. The faecal consistency score of pigs fed the 210 g/kg CP diet was higher (P , 0.05) than those fed the other diets. Pigs fed the 170 g/kg diet had lower (P50.02) small intestine weight than those fed the 210 g/kg CP diet. Pigs fed the 210 g/kg CP diet had deeper (P , 0.05) crypt in the duodenum and ileum and higher (P , 0.05) ammonia N concentration in caecal digesta than those fed the other diets. There were no effects of diet on microbial population and volatile fatty acid concentration in the caecal digesta except for propionic acid whose concentration was higher (P , 0.05) for pigs fed the 170 g/kg diet than those fed the 1901isoleucine and the 210 g/kg CP diets. The results indicate that the low-CP, AA-supplemented diet reduced crypt hypertrophy, ammonia N concentration in the caecal digesta, small intestine weight and the performance of piglets. Also, the results of the current study were inconclusive with respect to whether isoleucine may limit the performance of pigs fed a low-CP, AA-supplemented diet.

“…These results are consistent with those reported by Hu et al (2014), such that diets containing both soy protein concentrate and plasma had a greater beneficial effect on daily weight gain and average daily intake during the first post-weaning week. Ermer et al (1994) and Van Dijk et al (2001) suggested that the optimal performance during this period is related to the increased palatability of the feed with the inclusion of plasma and its health-promoting effects. However, in the present study, the use of feed with 2.5% SPC and 2.5% SPC promoted higher feed intake than that with 5% BP; yet, no significant difference in weight gain was observed.…”

-In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight of 7.01±0.294 kg, were distributed in a completely randomized block design, with three diets (0%SPC-5%BP, 2.5%SPC-2.5%BP, and 5%SPC-0%BP), six replicates, and three piglets per experimental unit. The experimental feeds were formulated to meet the requirements of the piglets at 21-32 and 33-42 days of age (pre-starter diet) and 43-66 days of age (starter diet). From 21 to 32 and 21 to 42 days of age, daily feed intake, daily weight gain, and final weight of the animals were higher in the group fed 2.5%SPC-2.5%BP and 0%SPC-5%BP. From 21 to 66 days of age, daily weight gain and daily feed intake were higher in the animals fed 2.5%SPC-2.5%BP. No effect was observed on the histomorphometry variables. The total leukocyte count was higher in animals fed 2.5%SPC-2.5%BP and 5%SPC-0%BP and the lymphocyte count was lower in the piglets that received 0%SPC-5%BP. The combined use of soy protein concentrate and spray-dried blood plasma in the feeds of piglets between 21 and 42 days of age improves their productive performance.
