В связи с принятием в РФ законопроекта, ограничивающего использование кормовых антибиотиков на комплексах по выращиванию животных, настоящее время ведется поиск альтернативы кормовым антибиотикам, частности, применению эфиромасличных культур кормлении цыплят бройлеров. Цель данной работы – систематизация данных отечественных и зарубежных исследований изучению свойств фитобиотиков эффективности их использования при выращивания сельскохозяйственной птицы различных направлений, а также экономической целесообразности примененич современном птицеводстве. Снижение риска развития инфекционных патологий использовании связывают формированием здоровой микробиоты пищеварительного тракта, которая способна обеспечить высокую резистентность к колонизации кишечника патогенами благодаря синтезу летучих жирных кислот, бактериоцинов других соединений, сдерживающих рост развитие патогенных видов. Ассортимент отечественного производства пока беден, однако последнее начинается идет активное продвижение области фитобиотических добавок. Основная причина отставания является низкий уровень внедрения производство, низкая конкурентоспособность технологий высокоэффективных добавок, отсутствие комплексных сфере. In connection with the adoption in Russian Federation of a bill limiting use feed antibiotics animal husbandry complexes, an alternative to is currently being sought, particular, essential oil crops feeding broiler chickens. The purpose this work systematize data domestic and foreign studies on properties phytobiotics effectiveness their growing agricultural poultry various areas, as well economic feasibility modern farming. reduction risk infectious pathologies when using associated formation healthy microbiota digestive tract, which can provide high resistance intestinal colonization by pathogens due synthesis volatile fatty acids, bacteriocins other compounds that inhibit growth development pathogenic species. range domestically produced still poor, but recently there has been active promotion field production phytobiotic additives. main reason for lag low level implementation production, competitiveness technologies highly effective additives, lack comprehensive area.

Intestinal disease is becoming increasingly prevalent in poultry production; however, the effect of BEC laying hens challenged with C. perfringens and coccidia limited. This study aimed to investigate effects dietary supplementation on intestinal ovarian health coccidia. A total 80 Lohmann gray (35 weeks) were randomly assigned two groups supplemented (0 or 1000 mg/kg). Each group contained 40 replicates, one bird each (one hen per cage). During sixth week trial, half (n = 20) administered mL (2.5 × 1010 CFU/mL) 0.15 (55,000 sporangia/mL), while other phosphate-buffered saline (PBS). The results indicated that those had severely damaged jejunal histopathological morphology, increased oxidative damage, decreased cecal acetic acid butyric content (p < 0.05), resulted lower gut microbial richness diversity. diet mg/kg reduced pathological damage short-chain fatty acids (SCFAs) content, enhanced diversity 0.05) Furthermore, positive associated changes composition structure.

The Role of Nutraceuticals and Phytonutrients in Chickens’ Gastrointestinal Diseases

Animals, Journal Year: 2022, Volume and Issue: 12(7), P. 892 - 892

Published: March 31, 2022

In poultry, severe gastrointestinal diseases are caused by bacteria and coccidia, with important economic losses in the poultry industry requirement of treatments which, for years, were based on use antibiotics chemotherapies. Furthermore, Salmonella spp., Clostridium perfringens, Campylobacter jejuni can cause serious foodborne people, resulting from consumption meat, eggs, derived products. With spread antibiotic resistance, which affects both animals humans, restriction livestock production identification a list “critically antimicrobials” became necessary. For this reason, researchers focused natural compounds effective alternatives to prevent disease poultry. This review summarizes results several studies published last decade, describing different nutraceutical or phytonutrients industry. The these products not always encouraging. While some have proven be very promising, further will needed verify efficacy practical applicability other compounds.

Efficacy of Rumex nervosus leaves or Cinnamomum verum bark as natural growth promoters on the growth performance, immune responsiveness, and serum biochemical profile of broiler chickens

Italian Journal of Animal Science, Journal Year: 2022, Volume and Issue: 21(1), P. 792 - 801

Published: April 25, 2022

This study was conducted to evaluate the potential growth and health promotion of Rumex nervosus leaves (RNL) Cinnamomum verum bark (CVB) supplementation as phytogenic promoters on broilers. For 34 days, 540 day-old broiler chicks were randomly assigned nine groups. Birds fed basal diet supplemented with 1, 3, or 5 g/kg RNL, 2, 4, 6 CVB. In addition, birds complemented antibiotic (AGP), without feed additive controls. All bird vaccinated for IBV, IBDV, NDV except negative control (NC). The selected indicators measured analysed. Broilers given 1 g RNL numerically heavier at days gained more a degree comparable AGP group (p = .053). addition CVB 2 resulted in best-feed conversion up 21 d .04). Throughout study, dietary treatments had no impact intake. Except ALT, none immune-related parameters serum biochemical profile differed statistically between when compared group. When comparing non-vaccinated un-treated day 34, vaccination increased significantly antibody titres IBDV. conclusion, CVB, especially low doses, attempted maximise performance compromising chickens under typical conditions. Further research into use natural herbs challenging conditions is required performance, maintain animal productivity, achieve ultimate goal reducing poultry industry. HighlightsCinnamomum dose improved ratio during starter period.

Journal of Poultry Sciences and Avian Diseases, Journal Year: 2024, Volume and Issue: 2(2), P. 36 - 49

Published: Jan. 1, 2024

The global poultry industry relies heavily on antibiotics to prevent and treat diseases promote growth. However, the rise of antibiotic-resistant bacteria poses significant risks both animal human health, necessitating alternative approaches maintain health productivity. This review systematically examines evidence for medicinal plants their bioactive components as non-antibiotic interventions growth promoters in species. Numerous herbs, spices, plant extracts, essential oils, isolated phytochemicals demonstrate beneficial bioactivities relevant production vitro vivo, including antimicrobial, anti-inflammatory, immunomodulatory, antioxidant effects. While considerable research confirms positive impacts performance under experimental conditions, questions remain regarding bioavailability, mechanisms, efficacy, safety, feasibility, suitability commercial integration that currently impede widespread adoption antibiotic alternatives. Further high-quality controlled trials directly analyzing physiological responses, impacts, safety profiles, cost-effectiveness analysis are warranted support evidence-based phytogenic feed additives systems.
