“…As expected, our study found that the villus-to-crypt ratio of small intestine were linearly improved by increasing dietary SID SAA:Lys. These findings are in agreement with the previous studies (Bauchart-Thevret et al 2009;Kaewtapee et al 2010;Kahindi 2014), they suggested that the improvement of small intestinal morphology as a result of increasing SAA or Met content in pigs diets. Therefore, it can be concluded that dietary SAA content promoted intestinal growth and abundant SAA could enhance enterocytes production by the crypt leading to longer villi.…”

This 10 wk feeding trial was conducted to determine the effect of increasing the standardised ileal digestible (SID) sulphur amino acid to lysine ratio (SAA:Lys) on performance and intestinal health parameters in growing-finishing (50-100 kg) pigs fed antibiotic-free diets. A total of 96 pigs [(Landrace Â Yorkshire) Â Duroc] with an average initial body weight (BW) of 52.2 ± 2.32 kg were randomly assigned to 4 dietary treatments each with 6 replicates (4 pigs per pen, 2 females and 2 males). The dietary treatments were 4 graded levels of SID SAA to Lys ratios (0.57, 0.67, 0.70 and 0.73). During the phase 1 (50-75 kg), pigs fed diets with increasing dietary SID SAA:Lys tended to improve the ADG (linear, p ¼ .07) and G:F (linear, p ¼ .06). During the phase 2 (75-100 kg), increasing SID SAA:Lys ratio had a tendency (linear, p ¼ .08) to improve the ADG and G:F. Furthermore, the villus-to-crypt ratio of duodenum were linearly increased (p < .05) by increasing SID SAA:Lys at the end of the experiment. Moreover, increasing SID SAA:Lys ratio linearly improved (p < .05) the ratio of faecal Lactobacillus:Escherichia coli in both phase 1 and phase 2. There was a linear decrease (p < .05) in ammonia when pigs were fed diets with increased SID ratio of SAA:Lys in both phase 1 and phase 2. In conclusion, increasing the dietary SID SAA:Lys provided beneficial effect on gut health of growing-finishing pigs fed antibiotic-free diets and showed partial positive effect in growth performance.

“…The measurements of villus height and crypt depth were performed on stained sections under the microscope with an ocular micrometer and 40× combined magnification. Villus height was measured from the villus tip to the villus‐crypt junction, whereas crypt depth was measured from this junction to the base of the crypt (Kaewtapee et al ; Walsh et al ; Shen et al ). At least 10 well‐oriented and intact villi and their associated crypts were measured in each slide.…”

A 3×2 factorial experiment was conducted to determine the effects of rearing system and stocking density on the growth performance, intestinal morphology and fermentation status of broilers. Broilers were kept on three rearing systems: floor litter rearing (FRS), plastic net rearing (NRS) and multilayer cage rearing system (CRS), each with two stocking densities (normal and high stocking densities). Results showed that on 7 to 28 days of age, body weight gain appeared as FRS > NRS > CRS. Whereas, CRS significantly enhanced the weight gain of broilers compared with the other systems subsequently. Broilers on FRS had higher counts of cecum Bifidobacteria and Lactobacilli at 28 days of age but had more Escherichia coli and less Bifidobacteria than CRS at 42 days of age. The FRS also decreased volatile fatty acid (VFA) concentration and jejunal villus height-to-crypt depth ratio at all ages. In conclusion, FRS appeared to benefit gut microorganisms during the early growing period along with high body weight gain of broilers, whereas this system might have a harmful effect on subsequent intestinal growth, as indicated by high E. coli, low Bifidobacteria count, low VFA concentration and villus height-to-crypt depth ratio along with low weight gain of broilers.

“…Due to the property of organic acids, Kaewtapee et al (2010) reported that adding LMA in drinking water reduced the total plate count and Escherichia coli (E. coli) in the water and consequently improved growth performance of piglets. In poultry, Poosuwan et al (2007) demonstrated that the minimum inhibitory concentration (MIC) of LMA for E. coli was 0.24% v/v in water, and this level promoted growth performance and tended to reduce E. coli in the gastrointestinal tract of broiler chicks.…”

ABSTRACT:This study was conducted to compare the effect of source of methionine (Met) in broken ricesoybean diet on performance, blood biochemistry, and fermentation characteristics in weaned pigs. Forty-eight male crossbreed pigs (BW 11 ± 0.1 kg) were randomly allocated to three groups with four replications in a completely randomized design. The experimental diets were: (1) basal diet without methionine (Control; total sulfur amino acids (TSAA) 0.60%); (2) basal diet supplemented with dl-methionine (DLM) (TSAA 0.76%); and (3) basal diet supplemented with dl-2-hydroxy-4-(methylthio) butanoic acid (LMA) (TSAA 0.76%). Supplementation with DLM and LMA improved growth performance of piglets and decreased blood urea nitrogen and increased serum albumin (P < 0.01). The population of Lactobacillus spp. in the caecum was decreased by both DLM and LMA supplementation (P < 0.05). Succinic acid concentration in the caecum of pigs fed the DLM diet was greater than that of LMA group (P < 0.05). It can be concluded that LMA can be used as a good source of Met (88% bioefficacy, weight/weight) in broken rice-soybean diet, although the serum albumin and fermentation characteristics (succinic acid) in the gastrointestinal tract were different.
