“…A further decrease in cell area in all epithelial cells might produce flat cells on the villus apical surface, resulting in a smooth surface seen in the PM400 group. Such flat cells were also reported in pigs undergoing a 3-day feed withdrawal (Mekbungwan et al, 2002). These studies suggest that the present decreased light microscopic parameters and the flat cells in PM groups might suggest histological atrophy.…”

Histological intestinal villus alterations were studied in piglets fed a raw pigeon pea meal (PM) diet including a powder mixture of amorphous charcoal carbon and wood vinegar compound solution (CWVC). Twenty-eight male castrated piglets were divided into seven dietary groups of four piglets each. The control group was fed raw PM supplemented to the basal diet (178 g/kg crude protein, 4.23 kcal/g gross energy) at 0 g/kg (CONT), 200 g/kg (PM200) and 400 g/kg (PM400). The treatment groups were fed CWVC in both PM200 and PM400 diet groups at levels of 10 g/kg and 30 g/kg (PM200 1 CWVC10, PM200 1 CWVC30, PM400 1 CWVC10 and PM400 1 CWVC30). With increasing dietary PM levels, daily feed intake tended to increase. In contrast, daily body-weight gain tended to decrease, significantly in the PM400 group (P , 0.05), resulting in a significant decrease of feed efficiency in PM groups (P , 0.05). Body-weight gain and feed efficiency were higher in the CWVC groups compared with the PM groups. The duodenum and ileum were longer (P , 0.05) in the PM400 group than in CONT, but were similar to CONT in CWVC groups. The liver was heavier (P , 0.05), whereas the weights of the heart, kidney and stomach were decreased in the CWVC groups than in other groups. Most values for the intestinal villus height, cell area and cell mitosis number were lower in PM groups than those in CONT (P , 0.05) for each intestinal segment; however, these values were higher in CWVC groups than in PM groups (P , 0.05). The epithelial cells on the duodenal villus surface of the PM200 group showed cell morphology almost similar to CONT. However, the PM400 group had a smooth villus surface due to the presence of flat cells. The epithelial cells of the CWVC groups were protuberated, resulting in a much rougher surface than CONT. The current growth performance and histological intestinal alterations in piglets fed PM and PM 1 CWVC diets demonstrate that the intestinal features might be atrophied by feeding PM, resulting in decreased growth performance. CWVC might prevent the harmful effects of PM dietary toxins on intestinal function, resulting in a normal growth performance.

“…Dietary constituents change not only digestibility of nutrients but also in ontogeny and morphology of the gastrointestinal walls (Noy and Sklan 1995;Uni et al 1998). Intestinal villi are the main site of nutrient absorption (Ray et al 2002) and their better development could be the reason for higher nutrient absorption (Mekbungwan et al 2002). In this study, we did not observe a significant increase in villus height by the treatments.…”

This study was carried out to investigate the effects of dietary supplementation of hydroalcoholic extract of Heracleum Persicum fruit (HPE) on performance, immune responses, small intestine morphology, haematological parameters and carcass characteristics of broiler chickens. A total of 300 day-old Ross 308 broiler chicks were used in a completely randomized design with five treatments and five replicates of 12 chicks each. The treatments were comprised of a corn-soybean meal base diet supplemented with five levels of HPE at 0(control), 100, 200, 300 and 400 mg/kg diet. Average daily feed intake (ADFI) was increased by 100 mg/kg of HPE comparing to control group during 11-24 d (p < 0.05). HPE at the levels of 200, 300 and 400 mg/kg, decreased (p < 0.05) serum cholesterol comparing to control group and showed a linear response to different levels of HPE (p = 0.0007). Also, LDL was decreased by 300 mg/kg of HPE (p < 0.05). The villus height to crypt depth ratio (VH/CD) was increased by 400 mg/kg of HPE, comparing to control group at 42 d (p < 0.05). Also, this ratio showed a linear response to different levels of HPE (p = 0.007). The results of this study indicated that HPE improves performance and intestine morphometrical and haematological parameters of broiler chickens. ARTICLE HISTORY

“…Besides, on the apical surface of the short villi of PM groups, flattened epithelial cells were observed [16]. Such flat cells were also reported in the pigs of 3-day feed withdrawal [18]. These studies suggest that the decreased light microscopic parameters and flat cells in the pigs fed PM might suggest atrophy due to the low digestibility of nutrients in the PM, and might related with the low function of the intestine.…”

“…From the fact that light microscopic parameters such as intestinal villus height, cell area and cell mitosis were decreased after fasting, but quickly recovered after refeeding [18,29,31], the higher values of the light microscopic parameters might be hypertrophied and related to the activated function of the intestine. Domelike epithelial cells on the tips of villi are also reported to be hypertrophied and found in the activated function of the intestine, while flat cells are atrophied and seen in the notas-activated intestinal function from a feeding experimental standpoint [18,31]. However, intestinal functions such as absorption for PM have not been actually measured in pigs fed PM until now.…”

“…The villus height showed a rapid alteration after rearing under various conditions [10,22,25], and the villus height and epithelial cells on the villus tip recovered immediately after refeeding in pigs [18]. The villi of the small intestine as well as epithelial cells on the duodenal villi were histologically much more hypertrophied in pigs fed SM than in those fed PM [19].…”

ABSTRACT. To compare the nutrient digestibility of soybean meal (SM) and pigeon pea seed meal (PM) as well as morphological intestinal alterations in piglets fed them, three pigs per group were randomly selected at the end of the feeding experiment for ten days. Growth performance was higher in the SM group than in the PM group (p<0.05). The digestibility of crude protein, crude fat and crude fiber was 80.6%, 23.6% and 52.4% in the SM group, while in the PM group, values of 49.8%, 23.6% and 43.2% were observed, respectively. Digestible energy was 3.26 kcal g -1 in SM and 3.17 kcal g -1 in PM. It was concluded that the digestibility of PM was lower than that of SM; almost half of the protein in PM was digested. Dietary treatments had no effect on length of each small intestinal segment and weight of visceral organs (small intestine, liver, heart, spleen, kidney, stomach and lung) except the decreased kidney weight in the PM group (p<0.05). The epithelial cells on the jejunal villi showed a dome-like shape in the SM group, but they were a flat shape in the PM group. The present digestion trial and histological intestinal data suggest that the intestinal digestive and absorptive functions are much more atrophied in the PM group than in the SM group, and demonstrate that histological intestinal alterations might be well related with the intestinal functions. KEY WORDS: digestibility, pigeon pea seed, soybean meal, swine.J. Vet. Med. Sci. 66(6): 627-633, 2004 Soybean meal (SM) is an important legume in the human diet, and also provides a large proportion of dietary plant protein in animal feed. The use of alternative legume seeds is encouraged to supply a constant plant protein source in animal feed and to reduce dependence on SM imported to Thailand. Pigeon pea (Cajanus cajan L.) is a perennial legume indigenous to tropical and sub-tropical regions, and pigeon pea seed meal (PM) has been studied widely from nutritional [20,30] and growth performance [4,7,20] standpoints. Although its use is limited by the higher content of anti-nutritional factors such as trypsin and chymotrypsin inhibitors than SM [2,34], Ene-Obong [7] has reported that such anti-nutritional factors do not cause problems in animals based on in vitro protein digestibility. In feeding experiments, PM could substitute SM in diets for pig based on growth performance [20]. However, a clear understanding of the nutrient digestibility in PM is still lacking. For ruminants, PM could be substituted for SM in diets based on its digestibility in sheep [4]. Compared with digestion trials using herbivores, the use of omnivores is crucial due to effects of feed ingredients other than PM on digestibility. In poultry, the metabolic energy of maize was established by feeding only one dietary component [6]. Amino acid digestibility of vetch was measured by force-feeding only one source of protein [8]. It was therefore concluded that an ingredient-feeding method described by these authors would be the most suitable method as an initial experiment of the digestibil...
