This study aimed to determine the cellulase activity in broilers digestive tract after the treatment of soya wastes and palm kernel fermented by A.niger (AKBIS Prob) in the ration. This study used a complete randomized factorial design, which consists of two factors, namely the AKBIS Prob composition factor and the duration of AKBIS Prob. Twenty four broilers were divided into four groups by randomized and three replications of each. The feed supplement combinations were P0 (commercial), P1 (commercial and AKBIS Prob 2%), P2 (commercial and AKBIS Prob 4%), and P3 (commercial and AKBIS Prob 6%). The intestine preparation was taken at the 22 and 36 days to extraction and detection the cellulase activity concentration. Data were analyzed using variance analysis of factorial patterns. AKBIS Prob 2,4 and 6% was no effect (P 0.05) to the cellulase activity in the small and large intestine, while the treatment duration was significant (P0,05) in the small intestine but neither in the large intestine (P0,05) to the cellulase activity. The addition of AKBIS Prob 2.4 and 6% had no effect (P 0.05) on the concentration of cellulase activity in the small intestine and large intestine, while the duration the treatment was very significant (P 0.05) in the small intestine and neither in the large intestine (P 0.05) on the concentration of cellulase activity. The AKBIS administration in the ration for 22 days can increase the activity and concentration of cellulase activity in the small intestine of the digestive tract of broiler chickens.

We studied anatomy and histology of different segments of the digestive tract in postnatal growing broiler chickens  with regard to their location, shape, size and weight. A group of four chickens, each at day 1 (D1), days 14 (D14) and  days 28 (D28), total 12, were killed, their digestive tracts were dissected and described and shape, size and weight of  different segments were recorded. Samples from different segments were prepared and stained with haematoxylin  and eosin staining technique to study the histology under light microscope. The average lengths (cm) and weights  (gm) of esophagus, proventriculus (glandular stomach), gizzard (muscular stomach), small intestine and large  intestine were significantly higher (P<0.01) in chickens at D28 than that at D14 and at D1. The histological layers of  digestive tract were lamina epithelia, lamina propria, lamina muscularis, submucosa, tunica muscularis and serosa  with the exception in esophagus where outer adventitia was found. The esophageal glands were significantly more in  numbers at D1 (in cross section, 12 in number per focus under 100x) than at D14 (6 in number per focus under 100x)  and at D28 (2 in number per focus under 100x). The proventriculus consisted of macroscopic papillae with numerous  microscopic folds with lamina propria comprised of simple glands, which converged into a common cavity near the  surface. In gizzard, the cuticle, in the form of wavy lines ran parallel to the surface. The villi of small intestine and  large intestine were lined by simple columnar epithelium. The apical parts of villi of the duodenum were slightly  pointed and the basal parts of the villi were thicker than jejunum and ileum, whereas, the villi of the jejunum and ileum  became shorter and broader than duodenum and most of the villi had blunt apical part and the basal parts were  wider. The numbers of goblet cells were numerous in number in ileum than duodenum and jejunum. Plicae ran along  the inner surface of the distal two thirds of the cacea. However, in the colorectum, the villi appeared as numerous  long flat leaf-shaped structures which filled a large proportion of the lumen. The average lengths and widths of villi of  small and large intestine were significantly higher (P<0.01) in chickens at D28 than that at D14 and at D1. The number  of goblet cells in lamina epithelium and intestinal glands of the lamina propria were numerous in number at D28 than  the chickens at D14 and at D1.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12096   J.

Excessive hunting and poaching for commercial purpose of Varanus salvator in Indonesia can cause a decline in this animal population. However, the scientific information of this animal especially about the biologic of organ system is rarely reported. Therefore, this case opens up opportunities for researching, which aims to study the anatomy of digestive tract of water monitor macroscopically. This research has been conducted in Biology Laboratory, University of Muhammadiyah Kupang for 5 months from March to August 2016. The digestive organ of this animal that has been preserved in alcohol 70% was obtained before from two males of water monitors. Preservation process: the animal were anesthetized, exsanguinated, and fixated in 4 paraformaldehyde by tissue perfusion method. Observations were performed to the visceral site and morphometrical of digestive tract. The resulted data was analysed descriptively and presented in tables and figures. The digestive tract of water monitor consist of esophagus, stomach, small intestine, large intestine and cloaca. The dimension of each organ is different based on its structures and functions. The esophagus of water monitor connects the mouth cavity and the stomach and also as the entrance of food to the stomach. Water monitor stomach were found in cranial part of abdomen, in left side of liver. The small intestine was longer than stomach and it is a winding muscular tube in abdomen in posterior side of liver. The large intestine consist of colon and cloaca, while cecum was not found. This channel was extend lateromedially in abdomen to cloaca between left and right kidneys. The cloaca was the end of digestive tract which excreted feces and urine. From this research, we can conclude that the digestive tract of water monitor consists of esophagus, stomach, small intestine, and large intestine. It’s difficult to differentiate small intestine and large intestine because there are no cecum.

This paper provides a macro- and microscopic description of the digestive tract of the kultarr (Antechinomys laniger), a small dasyurid marsupial. The digestive tract was simple, with no external differentiation between the small and large intestine, and lacked a caecum. Mean gross length of the kultarr digestive tract was 165.2 ± 32.1 mm. Microscopically, the tissues had cell types similar to those of other mammals. The new information will aid future post-mortem investigations of captive kultarrs and future studies of nutrition.

Four Holstein steers with cannulae in the rumen, proximal duodenum (PD) and terminal ileum (TI) were fed diets containing: (1) no added Mo or S; (2) Mo added at 10 mg kg−1; (3) S added at 3.0 g kg−1; and (4) Mo and S added at 10 mg and 3.0 g kg−1, respectively, in a Latin square design. Effects of Mo and S on minerals in the digestive tract of steers were evaluated. The solubility of Cu was lower with Mo (P < 0.01) and S (P < 0.01) at the PD and TI, and with Mo plus S (P < 0.05) at the TI. With Mo more (P = 0.07) Cu tended to be excreted in feces. Effects of Mo: Mn, reduced (P < 0.05) input to stomach region and higher (P < 0.01) absorption distal to PD; Zn, lower (P < 0.01) solubility at TI with less (P < 0.05) absorbed from large intestine (LI); Fe, more (P = 0.06) absorbed from LI with lower (P < 0.01) fecal excretion; P, lower (P < 0.05) input to stomach region with a tendency for less (P = 0.08) absorbed from small intestine (SI); Na, less (P < 0.05) absorbed from LI; K, lower (P < 0.05) apparent digestibility. Effects of S: Mn, slight tendency for higher (P = 0.10) absorption distal to PD; Zn, lower (P < 0.05) solubility at PD; P, less (P < 0.05) absorbed from SI and LI; Mg, tendency for less (P = 0.07) absorbed from stomach region and trend for more (P = 0.08) absorbed distal to PD. Minerals other than Cu were influenced by Mo and S in the digestive tract of cattle. Key words: Cattle, molybdenum, sulfur, digestion, minerals

Two series of assays involving a total of 120 growing rats were carried out to investigate the effect of varying levels of raw lima bean (RLB) on pancreatic and intestinal trypsin EC 3.4.21.4) and chymotrypsin (EC 3.4.21.1) activities. Experiment one indicates significant (P<0.01) inhibtion of both pancreatic trypsin and chymotrypsin due to RLB feeding. Enzyme activities in both the small and large intestine were also significantly (P<0.01) depressed while enzyme values in the caecum were not. Age x Diet interaction was non significant with respect to these enzymes. Pancreatic trypsin and chymotrypsin correlated significantly (P<0.01; P<0.05) with RLB with respective R2, coefficient of multiple determination, of 0.94 and 0.67. Trypsin activity in both the small and large intestine was also significantly (P<0.01) correlated with respective R2 of 0.78 and 0.96. The second study suggests a less than 10% replacement of cooked lima bean by the raw to avert significant pancreatic proteinase inhibition, and a less than 15% replacement of the cooked lima bean by the raw to aver t significantinhibition of the proteinases especially in the small intestine.

Today, the ulcerogenic effect of nonsteroidal anti-inflammatory drugs is a key factor that significantly limits their clinical use and is a serious medical and social problem, as these drugs are among the most commonly used drugs – they are used annually by about 5­–7% of the world's population. The aim is to characterize the antiulcerogenic effect of cryopreserved placenta extract and its application against the background of low temperatures in the model of diclofenac sodium-induced ulcerogenesis in rats according to macroscopic studies of the proximal and distal digestive tract. The study was performed on 42 male rats weighing 200–220 g. Acute diclofenac sodium-induced gastrointestinal damage was replicated by a single intragastric administration of diclofenac sodium to rats at a dose of 50 mg/kg. Euthanasia of animals was performed after 24 hours. The condition of the mucous membrane of the digestive tract was assessed on a scale and calculated integrated indicators – ulcer index and antiulcer activity. Cryocell-cryoextract of placenta was administered to rats intramuscularly at a dose of 0.16 ml/kg body weight. Cryoirrigation was performed once by local injection of liquid nitrogen vapor (temperature – 120˚C) for 10 s. It was found that diclofenac sodium at a dose of 50 mg/kg led to erosive-ulcerative damage to the gastric mucosa in 100% of rats, and the ulcer index was 3.9. The most pronounced leveling of the ulcerogenic effect of diclofenac sodium was observed against the combined preventive use of placental cryoextract and low temperature effect – the ulcer index was 12.6 times lower than that of rats with diclofenac sodium-induced ulcerogenesis without correction. Macroscopic evaluation of the distal gastrointestinal tract showed that the introduction of diclofenac sodium led to a statistically significant (p < 0.05) lesion of the mucous membrane of the small and large intestine in 42.9% of rats. According to the magnitude of antiulcer effect (%) in the model of diclofenac sodium-induced ulcerogenesis, the investigated prophylactic approaches for antiulcer activity have the following priority: action of low temperatures + cryoextract of placenta (96.7%) > cryoextract of placenta (92.1%) ~ esomeprazole (88.2%) > action of low temperatures (72.1%). No lesions of both the small and large intestine on the background of the introduction of placental cryoextract in the model of diclofenac sodium-associated ulcerogenesis were detected.

Experimental Substantiation

Based on the analysis of morphological and morphometric data, the clinical and experimental results of the effect of hypoxia on the wall of the small and large intestine in newborns are presented. The clinical part is based on the study of 58 case histories of patients with necrotizing enterocolitis, which the operating material (resected sections of the small intestine, large intestine) was studied in detail. The experimental work included the modeling of chronic hypobaric hypoxia in different trimesters of pregnancy in 4 groups of white rats (24 females). The offspring was taken out of the experiment at 4-5 days after birth, followed by collection of the small and large intestine areas to study histoarchitectonics. It is proved that hypoxia affects the number of newborn offspring, its weight. The small intestine is most vulnerable to the effect of this factor. Analysis of the morphological and morphometric picture of the operating and experimental material convincingly proves that under the influence of hypoxia the destruction of the intestinal mucosa occurs and the growth of the connective tissue component in the muscle layer occurs. Changes from the microcirculation of blood and lymph provoke the development of pre-ulcerative, ulcerative defects and the formation of necrosis. Disturbance of the drainage function promotes the spread of destruction in the intestinal wall.

The utilization of Shea butter cake (SBC), a by-product of fat extraction from sheabutter nuts (Butyrospennum paradoxum) was compared with Palm Kernel Cake (PKC) to establish its potential as a poultry feedstuff. A 2 x 3 factorial experiment combining two factors, SBC and PKC at three levels of inclusion (5%, 10% and 15%) was designed. The six dietary treatments were fed to a total of 180 day-old chicks up to 56 days of age. Broilers fed SBC diets consumed more feed (P < 0.05) than those fed PKC diets between 0-28 days of age. During the finisher period (29-56d) and the entire period (0-56d)feed intakes of broilers were similar (P >0.05) on the treatment except the low consumption (P < 0.05) by those fed 5% SBC. Broiler chicks fed 5% attained the heaviest weight gain (P > 0.05) which compared with chicks fed 15% PKC between 0-28d. Between 29-56d, growth rates of broilers were uniformly higher (P < 0.05) on PKC than SBC diets. Broilers fed 15% SBC had the least (P < 0.05) weight gain at the three (0-28d; 29-56d and 0-56d) periods. Considering the entire period (0-56d), growth rates were not significantly (P >0.05) different on SBC diets up to 10%, and on PKC diets  up to 15%. Feed efficiency and protein efficiency rations of the broiler became poorer (P < 0.05) with increasing levels of SBC in both growth phases unlike broiler fed PKC which had similar values irrespective of the levels of inclusion. The intestinal tracts and visceral organs were not influenced (P > 0.05) by the sources and levels of test ingredients except abdominal fat which was higher on SBC than PKC at 10% and 15% levels of SBC 10% level was optimal.

Small And Large Intestine

Cyclical propagating waves of muscle contraction have been recorded in isolated small intestine or colon, referred to here as motor complexes (MCs). Small intestinal and colonic MCs are neurogenic, occur at similar frequencies, and propagate orally or aborally. Whether they can be coordinated between the different gut regions is unclear. Motor behavior of whole length mouse intestines, from duodenum to terminal rectum, was recorded by intraluminal multisensor catheter. Small intestinal MCs were recorded in 27/30 preparations, and colonic MCs were recorded in all preparations ( n = 30) with similar frequencies (0.54 ± 0.03 and 0.58 ± 0.02 counts/min, respectively). MCs propagated across the ileo-colonic junction in 10/30 preparations, forming “full intestine” MCs. The cholinesterase inhibitor physostigmine increased the probability of a full intestine MC but had no significant effect on frequency, speed, or direction. Nitric oxide synthesis blockade by Nω-nitro-l-arginine, after physostigmine, increased MC frequency in small intestine only. Hyoscine-resistant MCs were recorded in the colon but not small intestine ( n = 5). All MCs were abolished by hexamethonium ( n = 18) or tetrodotoxin ( n = 2). The enteric neural mechanism required for motor complexes is present along the full length of both the small and large intestine. In some cases, colonic MCs can be initiated in the distal colon and propagate through the ileo-colonic junction, all the way to duodenum. In conclusion, the ileo-colonic junction provides functional neural continuity for propagating motor activity that originates in the small or large intestine. NEW & NOTEWORTHY Intraluminal manometric recordings revealed motor complexes can propagate antegradely or retrogradely across the ileo-colonic junction, spanning the entire small and large intestines. The fundamental enteric neural mechanism(s) underlying cyclic motor complexes exists throughout the length of the small and large intestine.

The effect of heat treatment on canola meal (CM) dry matter (DM) and nitrogen (N) degradability in the rumen and digestion in the small and large intestines and total digestive tract of steers was determined. CM was moist-heat-treated at 127 °C for 15 and 45 min. The degradation of DM and N was estimated using small nylon bags in the rumen for 0.1, 4, 8, 12, 16, 24, 48 and 72 h. The mobile bag technique with an in vitro incubation in an acid-pepsin solution was used with a separate set of bags to estimate the digestion of each nutrient in the small and large intestines as well as the total digestive tract for rumen incubation times of 8, 16 and 24 h. Chemical analysis of heated CM showed a significant reduction in soluble N, sucrose and glucosinolate content while the concentration of ADIN increased. Treatment significantly reduced the degradation of DM and N in the rumen while the digestibility of DM and N in the small intestine increased with both treatments proportional to the decreased rumen degradation. Heat treatment had no effect on DM and N digestibility at the large intestine site. Total tract disappearance of DM and N were not affected by 15 min heating; however, after 45 min heating, DM and N disappearances were reduced. Moist heat treatment was effective in reducing rumen disappearance of CM nitrogen while it increased the N digestion in the small intestine. Key words: Heat treatment, canola meal, ruminant intestine, protein digestion
