Enteric histology of newborn goat kids fed lyophilized bovine colostrum (LBC) was studied. At 0, 7, and 14 h of life 15 male newborns received 5% of body weight of lyophilized bovine colostrum and 14 male newborns goat colostrum (GC), both with 55 mg/ml of IgG. Samples of duodenum, jejunum, and ileum were collected at 18, 36, and 96 h of life for analyses of villus height, crypt depth, muscle layer thickness, partial volume of the absorptive mucosa (Vv), density of the absorptive mucosa (Sv), and quantification of goblet cells. Three animals were sampled without colostrum intake (0 h). The histomorphometry was not different between GC and LBC in all segments. In the jejunum, the villus height differed in sampling times (36 h > 0 h and 18 h). The maximum villus height was observed in the jejunum. In the jejunum, crypt depth differed in the sampling times (96 h > 0 and 18 h). Interaction between intestinal segment and sampling times was observed to crypt depth (duodenum 18 h > jejunum 18 h and duodenum 96 h > ileum 96 h). In the ileum, the muscle layer thickness differed in the sampling times (36 h > 0 and 18 h and 96 h > 0 h). The greatest thickness of muscle layer was observed in the duodenum and at 96 h the muscle layer was thicker than at 18 h. The ileum showed the highest Vv at 36 h. The Vv was the highest in the jejunum and higher at 36 h than at 96 h. In the jejunum, an interaction between the treatment and sampling times to goblet cells number (LBC 18 h < GC 18 h and GC 96 h > LBC 96 h) was observed. The ileum showed the greatest number of goblet cells. The ingestion of lyophilized bovine colostrum did not determine any consequences for enteric histology in the first 4 days of goat kids’ life.

The aim of this study was to investigate histology characteristics in the small intestine of Santa Ines lambs fed bovine or ovine colostrum. At 0 and 6 h of life, 12 newborn lambs received 250 ml of first milking bovine colostrum (BC) and another 12 animals received 250 ml of first milking ovine colostrum (OC). Samples of duodenum, jejunum and ileum were collected at 24 and 72 h of life. Six animals were sampled at birth, without colostrum intake (0 h). The histomorphologic analysis revealed differences between BC and OC groups in the jejunum and ileum segments. BC group had higher amounts of colostrum-filled vacuoles in the intestinal epithelium compared to OC group and the latter group had a higher number of empty vacuoles. However, at 72 h of life both groups revealed the end of the intestinal colostrum absorption. Regardless of the treatment, apical nuclei and vacuoles were mainly observed in the villi of animals at 0 and 24 h of life, and at 72 h the enterocytes had basal nuclei and cytoplasm without the presence of vacuoles. An interaction between treatment and period was observed in villus height and crypt depth in the jejunum (P < 0.05). In this segment, BC group showed the lowest villus height at 24 h of life (710.37 ± 115.79 µm) while OC group had the larger villus height (883.79 ± 207.24 µm) at 24 h than at 0 h of life (791.43 ± 129.19 µm) (P < 0.05). Lambs from BC group showed the deepest crypts at 72 h (157.15 ± 41.81 µm), followed by 24 h (100.08 ± 23.40 µm) and 0 h (84.89 ± 21.10µm), and in OC group the deepest crypts were observed at 0 h (84.89 ± 21.10 µm), without the colostrum ingestion (P < 0.0%). The effects of treatment on the crypt depth were observed in the ileum (P < 0.05), crypts in BC group were deeper than in OC group (92.67 ± 21.47 and 83.12 ± 13.85 µm, respectively). The histological changes related to the ingestion of bovine colostrum did not apparently determine any consequences for enteric physiology. Thus, the results concerning the histologic and histomorphometric aspects confirm a possibility of successfully using bovine colostrum as a substitute for ovine colostrum in newborn lambs.

The experiment aimed to investigate the effects of dietary β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of nutrients, intestinal integrity, and the immunological and oxidative stress parameters in weaning pigs. A total of 64 newly weaning pigs (initial body weight: 6.96 ± 0.70 kg) were allotted to two dietary treatments in eight replicates per treatment with four pigs per pen based on body weight and sex. Dietary treatments were 1.) CON (control: corn-soybean meal based basal diet) and 2.) β-mannanase (basal diet +0.06% β-mannanase). The β-mannanase supplementation did not affect growth performance, concentrations of acute phase protein, superoxide dismutase and glutathione peroxidase. However, the pigs fed the β-mannanase-supplemented diet had greater ATTD of ether extract, jejunum villus height, and villus height-to-crypt depth ratio, and lower crypt depth compared with those fed the CON diet (p < 0.05). The pigs fed the β-mannanase-supplemented diet tended to have the lower count of E. coli in cecum than those fed the CON diet (p = 0.08). In conclusion, dietary β-mannanase supplementation did not affect growth performance, immune response and oxidative stress of weaning pigs, whereas it increased fat digestibility and had positive effects on intestinal integrity and cecum microflora by reducing the count of E.coli.

To investigate the effects of the ratio of insoluble fiber to soluble fiber (ISF:SF) on sow performance and piglet intestinal development, we randomly assigned 64 gilts to four treatments comprising diets with the same level of dietary fiber, but different ISF:SF values of 3.89 (T1), 5.59 (T2), 9.12 (T3), and 12.81 (T4). At birth and weaning, six piglets per treatment at each phase were slaughtered for sampling. As ISF:SF increased, the mean piglet body weight (BW) at weaning and piglet BW gain, which were all significantly higher in T1 and T2 compared with T3 and T4 (p < 0.05), showed a linear decrease (p < 0.05); the crypt depth of the jejunum in weaned piglets linearly increased, whereas the duodenal weight, jejunal villus height, and villus height/crypt depth in newborn piglets and enzymatic activity of lactase, sucrase, and maltase linearly decreased (p < 0.05). No differences were observed in the yield and composition of milk (p > 0.05). Moreover, when the ISF:SF was 3.89 in gestation diets, higher piglet BW at weaning occurred, possibly because the ISF:SF affected development and enzymatic activity in the small intestine—effects related to digestion and absorption of nutrients—and consequently enhanced piglet BW gain.

Abstract. The present study was planned to investigate the effect of different levels of chlorine dioxide on the performance, gut microbiota and intestinal histology of quails. For this purpose, 300 day-old healthy quail chicks were randomly placed in 20 specially designed pens (15 birds/pen) with water troughs containing chlorine dioxide at the level of 0.00 (DW-0.00), 0.3 (DW-0.3), 0.4 (DW-0.4) and 0.5 ppm (DW-0.5) in replicated fashion (5 replicate/treatment) for 28 days. Weight gain, feed conversion ratio and dressing percentage increased significantly (P<0.05) in DW-0.5 group. Similarly, liver, gizzard and heart weight increased significantly in treated groups linearly with increasing levels of treatment at day 21 and 28. The results showed that population of Salmonella and E. coli decreased linearly at day 21 and 28 of age. Villus height and goblet cells at day 21 and 28 were significantly higher in DW-0.5 group. The results of the present study suggested that the treatment of chlorine dioxide linearly increased the performance and gut morphology and decreased microbial population in quails.

Abstract Introduction: This study examined the effect of dietary Moringa oleifera leaf meal (MoLM) supplementation on intestinal structure vis-à-vis body weight gain in chickens. Materials and Methods: A total of 120-day-old Arbor Acres broiler chicks were randomly assigned to four groups, each with three replicates, 10 birds per replicate. Broiler feed supplemented with different quantities of MoLM, viz.: group T1 (control) - 0%, T2- 7.5%, T3- 15% and T4- 30%, was fed to the birds for 38 days, after which six birds/group were randomly selected and euthanized for histological work. Results: Normal histology was evident in the various intestinal components except the lamina propria and crypts in T4 and villus muscle strands in T3 and T4 where degenerative changes were observed. Villus height, crypt depth, muscle wall thickness and villus area in T1 (controls) were 935.6 pm, 173.8 pm, 192.5 pm and 0.19 mm-2, respectively. Relative to the controls, an increase in the afore mentioned measurements was noted in T2 (6.4%, 8.4%, 10.6% and 10.5%, respectively) while a reduction was recorded in T3 (16.1°%, 10.8°%, 14.8°% and 15.8°%, respectively) and T4 (20.1°%, 14.7°%, 18.3°% and 21.1°%, respectively). Body weight gain within the feeding period increased 31.2, 37.6, 23.9 and 10.9-fold in T1, T2, T3 and T4, respectively. Notably though, feed intake and villus height/ crypt depth ratio were not significantly different (p < 0.05) between dietary treatments. Conclusion: Inclusion of M. oleifera in the diet should be done in moderation as quantities ≥ 15% interfere with intestinal structure and consequently body weight gain.

The restriction and banning of antibiotics in farm animal feed has led to a search for promising substitutes for antibiotics to promote growth and maintain health for livestock and poultry. Ginsenoside Rg1, which is one of the most effective bioactive components in ginseng, has been reported to have great potential to improve the anti-inflammatory and anti-oxidative status of animals. In this study, 360 Chinese indigenous broiler chickens with close initial body weight were divided into 5 groups. Each group contained 6 replicates and each replicate had 12 birds. The experimental groups were: the control group, fed with the basal diet; the antibiotic group, fed basal diet + 300 mg/kg 15% chlortetracycline; and three Rg1 supplementation groups, fed with basal diet + 100, 200, and 300 mg/kg ginsenoside Rg1, respectively. The growth performance, immune function, and intestinal health of birds were examined at early (day 1–28) and late (day 29–51) stages. Our results showed that dietary supplementation of 300 mg/kg ginsenoside Rg1 significantly improved the growth performance for broilers, particularly at the late stage, including an increase in final body weight and decrease of feed conversion ratio (P &lt; 0.05). Additionally, the integrity of intestinal morphology (Villus height, Crypt depth, and Villus height/Crypt depth) and tight junction (ZO-1 and Occludin), and the secretion of sIgA in the intestine were enhanced by the supplementation of Rg1 in chicken diet (P &lt; 0.05). The immune organ index showed that the weight of the thymus, spleen, and bursa was significantly increased at the early stage in ginsenoside Rg1 supplementation groups (P &lt; 0.05). Our findings might demonstrate that ginsenoside Rg1 could serve as a promising antibiotic alternative to improve the growth performance and gut health for broiler chickens mainly through its amelioration of inflammatory and oxidative activities.

This study aimed to investigate the effect of dietary sunflower meal (SFM) and multi-enzyme levels on performance, carcass traits, intestinal histomorphology and pancreatic enzyme production in quails. Three hundred and twenty, 1-day-old quail chicks were divided into 8 groups with 4 replicates consisting of 10 birds each in the group. The experiment was randomized design consisting of a 4 × 2 factorial arrangement, with four levels of SFM (0%, 10%, 15%, or 20%) and two levels of multi-enzyme (0.0 or 1.0 g/kg) inclusion in the diet. The body weight, body weight gain, and feed conversion ratio were negatively influenced by the 15% and 20% SFM (p < 0.01) but were not affected by the 10% SFM for 6 week age. The relative gizzard (p < 0.05) weights significantly increased with 20% SFM, but the relative breast weight decreased (p < 0.01). The relative liver weight increased by the addition of enzymes in the diet (p < 0.05). The villus width (p < 0.01) and villus surface area (p < 0.05) of ileum increased linearly with SFM, whereas the villus height (p < 0.01), villus height: crypt depth (p < 0.01) and tunica muscularis thickness (p < 0.01) decreased linearly with SFM. Consequently, it is possible to say that the birds with the least absorptive same weight are the most efficient. The addition of multi-enzyme increased villus height and crypt depth but decreased tunica muscularis thickness of ileum (p < 0.01). Chymotrypsin activity in the pancreas decreased linearly with SFM (p < 0.01). Amylase activity in the pancreas decreased significantly with the addition of the multi-enzyme (p < 0.05). As a result of the study, SFM can be used at a 10% level in growing quail diets with beneficial effects on the absorption surface area. The effects of enzyme supplementation on parameters measured were less pronounced than the SFM inclusion level that higher villus height and lower tunica muscularis thickness were determined in multi-enzyme-fed birds compared to those untreated counterparts.

Abstract Rosemary (Rosmarinus officinalis L.) extract (RE) has multiple pharmacological and biological activities, including use as a food additive and medicine. This study was conducted to investigate the effects of dietary RE supplementation on the growth performance, nutrient digestibility, antioxidant capacity, intestinal morphology and microbiota of weaning piglets. A total of 192 crossbred weaned piglets [Duroc × (Large White × Landrace)] (initial body weight = 6.65 ± 0.33 kg, weaned days = 23 ± 1 d) were group housed (six pigs per pen; n = 8 pens/treatment). Pigs were fed a corn-soybean meal-based control diet or the basal diet supplemented with 100, 200 or 400 mg/kg RE. Pigs were allowed ad libitum access to fed for 21-d. The growth performance and apparent total tract digestibility of nutrients, and intestinal morphology and antioxidant status were evaluated. The components of the microbial microflora were also determined in the cecal samples. Compared with the control, dietary supplementation with RE increased the final body weight, average daily gain and average daily feed intake (linear, P = 0.038, 0.016, and 0.009, respectively), and decreased the diarrhea ratio in piglets (linear, P &lt; 0.05). The digestibility of crude protein (linear, P = 0.034) and gross energy (linear, P = 0.046) increased with treatment with RE. Piglets fed RE showed longer villus height (linear, P = 0.037 and 0.028, respectively) and villus height/crypt depth (linear, P = 0.004 and 0.012; quadratic, P = 0.023 and 0.036, respectively) in the jejunum and ileum, in addition to a lesser crypt depth in the jejunum (linear, P = 0.019) and ileum (quadratic, P = 0.042). The addition of RE increased the activity of superoxide dismutase (linear, P = 0.035 and 0.008 respectively) and glutathione peroxidase activity (linear, P = 0.027 and 0.039 respectively), and decreased the content of malondialdehyde (linear, P = 0.041 and 0.013; quadratic, P = 0.023 and 0.005 respectively) in the serum and liver. Dietary RE supplementation, compared with the control, increased the number of Bifidobacterium (linear, P = 0.034) and Bacteroidetes (linear, P = 0.029), while decreased Escherichia coli (linear, P = 0.008; quadratic, P = 0.014) in the cecal contents. Thus, dietary RE supplementation can improve growth performance, nutrient digestibility, antioxidant capacity, intestinal morphology and the microbiota in weaned piglets, and 200 mg/kg may be considered the optimum dosage.

The objective of this study was to evaluate the efficacy of mycotoxin binders in reducing the adverse effects of co-occurring dietary aflatoxin B1 (AFB1), deoxynivalenol (DON) and ochratoxin A (OTA) on laying hens. Three hundred and sixty 26-week-old Roman laying hens were randomly allocated into four experimental groups with 10 replicates of nine birds each. The four groups received either a basal diet (BD; Control), a BD supplemented with 0.15 mg/kg AFB1 + 1.5 mg/kg DON + 0.12 mg/kg OTA (Toxins), a BD + Toxins with Toxo-HP binder (Toxins + HP), or a BD + Toxins with TOXO XL binder (Toxins + XL) for 12 weeks. Compared to the control, dietary supplementation of mycotoxins decreased (P < 0.10) total feed intake, total egg weight, and egg-laying rate, but increased feed/egg ratio by 2.5–6.1% and mortality during various experimental periods. These alterations induced by mycotoxins were alleviated by supplementation with both TOXO HP and XL binders (P < 0.10). Furthermore, dietary mycotoxins reduced (P < 0.05) eggshell strength by 12.3% and caused an accumulation of 249 μg/kg of DON in eggs at week 12, while dietary supplementation with TOXO HP or XL mitigated DON-induced changes on eggshell strength and prevented accumulation of DON in eggs (P < 0.05). Moreover, dietary mycotoxins increased relative liver weight, but decreased spleen and proventriculus relative weights by 11.6–22.4% (P < 0.05). Mycotoxin exposure also increased alanine aminotransferase activity and reduced immunoglobulin (Ig) A, IgM, and IgG concentrations in serum by 9.2–26.1% (P < 0.05). Additionally, mycotoxin exposure induced histopathological damage and reduced villus height, villus height/crypt depth, and crypt depth in duodenum, jejunum and (or) ileum (P < 0.05). Notably, most of these histological changes were mitigated by supplementation with both TOXO HP and XL (P < 0.05). In conclusion, the present study demonstrated that the mycotoxin binders TOXO HP and XL can help to mitigate the combined effects of AFB1, DON, and OTA on laying hen performance, egg quality, and health.
