Structural Changes in the Digestive Tract of Broilers when Introducing a Probiotic

Abstract

The authors have studied the influence of a probiotic and a gastrointestinal adsorbent on the histostructure of the digestive tract of broilers. Day-old broilers were divided into groups of 50 heads each by the method of analog pairs in terms of live weight. Control broilers received a basic diet. Broilers of the 1st experimental group during the first three days of the experiment received probiotic Vetom-1.1 (0.006%) containing spores of Bacillus subtilis with the basic diet, and broilers of the 2nd experimental group received gastrointestinal adsorbent Enterosgel (0.008%). For histological studies, three heads of broilers were selected at day 1 of age, day 4 of age, and at the end of the experiment (after the end of feeding the preparation and before the transition to the basic diet) from the average weight of each group. Samples were excised from the middle of the crop, the glandular part of the stomach, the duodenum, the jejunum, and the proximal part of the cecum of birds. At the end of the experiment, the positive aftereffect of the preparation persisted in the crop and duodenum. At the same time, in the experimental group, the thickness of the submucous membrane of the stomach decreased, and in the cecum, the layer of villi increased.

Network and structural analysis of quail mucins with expression pattern of mucin 1 and mucin 4 in the intestines of the Iraqi common quail (Coturnix coturnix)

“…This study noted an unexpectedly high neutral MUC expression in the jejunum, which warrants further investigation regarding its functional significance. In various diseases, shifts in the equilibrium between acidic and neutral MUCs have been detected [ 44 , 45 ]. IBD in humans is characterized by a shift from neutral to acidic MUCs [ 46 , 47 ].…”

Развитие Бокаловидных Клеток Двенадцатиперстной Кишки Бройлеров При Скармливании Энтеросорбента Со Статовым Рационом

“…В исследовании механизмов адаптации ключевую роль играет желудочно-кишечный тракт, так как с его стенкой контактирует огромное количество компонентов корма, антигенов и бактерий. Следовательно, поверхность слизистой этих органов будет одной из первых реагировать на различные кормовые добавки [1].…”

“…В двенадцатиперстной кишке наблюдалось увеличении высоты ворсинок. В каудальном направлении действие этого препарата снижалось и в толстом отделе положительное влияние наблюдалось только в конце периода выращивания [1]. Так как самые значимые морфологические изменения наблюдались в начальном отделе кишечника, представляет интерес изучение влияния сорбента на количество и распределение бокаловидных клеток в двенадцатиперстной кишке птицы.…”
