“…The effect of the use of prebiotics for growth, feed intake, and feed efficiency shows a varied response and did not influence piglet performance during the nursery period, for prebiotics such as mannooligosaccharides (CORASSA et al, 2012;SANTOS et al, 2010;SILVA et al, 2012), fructoligossacharides (VISENTINI et al, 2008), and chitooligossacharides (CHEN et al, 2009). However, with COS, some studies have reported better growth and feed efficiency in broilers (HUANG et al, 2005;LI et al, 2007) and piglets Apical villi necrosis 3 0 a 3…”

The objective of this study was to evaluate the dose-response effect of a chitooligosaccharide (COS) produced by Universidade Estadual de Londrina over performance, diarrhea episodes, visceral characteristics and morphometry. A total of 72 Pen Ar Lan ® piglets were weaned at 23 days and 7.51 ± 1.35 kg of BW. The treatment was a basic diet plus inclusion of 0, 50, 100, or 150 ppm of COS (100 mg/kg). For the visceral and morphometric evaluation, 24 animals were slaughtered at 31 days of age with 11.01 ± 1.25 kg of BW. No regression effect over the performance or diarrhea prevalence was observed. Higher doses of COS led to higher absolute values for large intestine weight, villus height in the jejunum and crypt depth in the jejunum and ileum; the villus/crypt ratio in the ileum was higher until the level of 100 ppm COS. More lesions were observed in the intestinal epithelium along with a higher total number of lymphocytes and eosinophils in the duodenum. High numbers of eosinophils were observed in the ileum when a higher level of COS was used. In general, increasing levels of COS led to better intestinal morphometry and activated somatic cells in the lamina propria of the piglet intestine; however, no influence was observed in the productive performance of these animals. Considering all studied parameters, the COS level of 100 ppm was the most promising under these experimental conditions. Key words: Nursery. Diarrhea. Prebiotic. Performance. Alternative. Oliveira, E. R. et al. Resumoe peso de órgãos de leitões aos 31 dias de idade. Foram utilizados 72 leitões de genética Pen Ar Lan®, desmamados com idade média inicial de 23 dias e peso de 7,51 ± 1,35 kg. Os tratamentos consistiram em uma dieta base com os níveis de inclusão de 0, 50, 100 e 150 ppm de QOS. Para a avaliação visceral e morfohistométrica, 24 animais foram abatidos aos 31 dias de idade e peso de 11,01 ± 1,25 kg. Não houve efeito de regressão sobre o desempenho ou incidência de diarreia. O aumento da dose utilizada de QOS levou a um aumento nos valores referentes ao peso relativo do intestino grosso, à altura de vilosidades de jejuno e à profundidade de cripta no jejuno e íleo, enquanto que, a relação vilos/cripta deste último segmento foi crescente apenas até o uso de 100 ppm de QOS. Observou-se aumento de lesões no epitélio intestinal e contagem de linfócitos e eosinófilos no duodeno e eosinófilos também no íleo com o aumento da dose do QOS até 150 ppm. De maneira geral, os níveis crescentes de QOS melhoraram a morfofisiologia intestinal e ativaram a células somáticas na lâmina própria do intestino dos leitões, entretanto, não houve influência sobre o desempenho produtivo dos animais. Frente a todos os parâmetros estudados, o nível de 100 ppm de QOS mostrou-se o mais promissor para as condições propostas por este experimento. Palavras-chave: Creche. Diarreia. Prebiótico.

“…Regarding TP and albumin, Silva et al (2012) found values of 4.77 g/dL TP and 2.27 g/dL of albumin, Moreira et al (2014) obtained a value of 7.02 g/dL of TP and Rocha et al (2012) obtained a value of 4.14 g/dL albumin, with the range considered ideal for this protein being among 1.9-3.9 g/dL (Kaneko et al, 2008). Values below the optimal range of 6-8 g/dL (Weiss & Wardrop, 2010) were observed for TP, due to the reference values being not regional, as well as due to the nutritional management used in each specifically production system, independently from the type of packaging (insolation or EE).…”

Ethical and commercial issues are associated with animal welfare in pig farming, in that sense, the objective of this work was to evaluate physiological and blood parameters in addition to weight gain in pigs raised with and without sunlight and environmental enrichment (EE), as well as to correlate physiological and environmental parameters as welfare indicators. Twenty-four pigs distributed in a randomized block design with a 2 × 2 factorial arrangement were used. Blocks were represented by shifts (morning and afternoon), and factors by the presence or absence of EE and sunlight. Blood and environmental parameters of thermal comfort, in addition to weight gain, were registered. Physiological parameters showed to be shift dependent (p < 0.05), with the afternoon shift being superior when compared to the morning shift, thus indicating climate influence. Weight gain showed significant interactions (p < 0.05) in the presence and absence of sunlight and EE in the stalls. Temperature correlated positively with the physiological parameters. Moisture showed negative correlations with physiological parameters. The packed cell volume was lower (p < 0.05) in the presence of EE. The EE provides physiological well-being and weight gain for pigs in the nursery stage, especially when sunlight was absent in the stalls.
