The poultry gastrointestinal microbiome consists of more than 900 bacterial species and their metabolites; it serves as an indicator of bird health and is influenced by nutrition, medication, and other factors. Dysbiosis is a form of reduced microbial diversity, characterised…
The effects of poultry fat (PF) as an alternative to soy oil (SO) in broiler diets at a fixed energy:protein on field performance were investigated. Chick weight (CW), average daily weight gain (ADWG), average live weight (ALW), feed consumption (FC),…
The study aimed to assess the effect of different dietary levels of a probiotic blend (Probio Enzyme®) during the first 14 days of age (DOA) or up to 42 DOA, on growth performance, carcass and digestive tract traits, and haematological…
The objective of this study was to evaluate the dietary supplementation of Phyllanthus niruri L. powder (meniran powder, MeP) on the productivity, haematology profiles, and intestinal morphology of broilers. A total of 200 female, one-day-old chickens were allocated to five…
The aim of this study was to evaluate the effects of dietary Piriformospora indica (PI) and clove essence (CE) and a combination of them (synbiotic) on performance and biochemical parameters after induction of stress using dexamethasone. The experiment was performed…
The objective of this study was to evaluate the effect of dietary onion (Allium cepa) and ginger (Zingiber officinale) supplementation on growth, carcass quality, antioxidant status, and immune response in broilers under heat stress. A total of 700 day-old Hubbard…
Effects of dill powder (Anethum graveolens dhi) on performance and biochemical traits, immune response, blood cells and microbial population of cecum broilers after stress induced with dexamethasone were investigated. Two hundred and forty broilers were arrayed in completely randomized design…
Yeast cultures (YCs) are defined as promising feed additives that maintain the health of birds and improve growth performance by modulating gut microbiota. YCs contain effective metabolites such as glycine, fructose, inositol, galactose, and sucrose. This study investigated the effects…
The aim of the research was to determine whether enrichment of the atmosphere in an incubator with carbon dioxide (CO2) and oxygen (O2) and eggshell thickness (EST) affected embryonic death (ED), hatchability of fertile eggs (HFE) and hatching time (HT)…
The study evaluated supplementation of broiler diets with a protease enzyme. Six hundred Ross 308 female broiler chicks were acquired at one day of age and randomly distributed to three treatments with five replicates of 40 chicks each. The experimental…
The hypothesis was that owing to their high bioavailability, zinc oxide nanoparticles (NanoZnO) can effectively replace (Zn) salts and reduce Zn excretion with faeces. The objective of this study was to investigate the effects of NanoZnO on the development of…
This study assessed the effects of dietary supplementation of probiotics, antibiotics and an antibiotic-probiotics mixture on growth performance of broilers, and the fatty acid profile and oxidative stability of broiler breast muscle. A total of 480 one-day-old broiler chicks (Cobb…
This experiment was conducted to investigate the effects of various levels of organic acids and virginiamycin on performance, blood parameters, immunoglobulin and microbial population of broiler chickens. This trial was conducted in a completely randomized design using five treatments and…
The present study aimed at evaluating the effect of a phytogenic mixture in the diet on broiler production. A total of 400 day-old unsexed Cobb broiler chicks were randomly allotted to four treatment groups of 10 replications in a randomised…
Two experiments were conducted to investigate the effects of fortification of the pre-starter diet with glutamine in post-hatch broiler chicks. In the first experiment, male chicks were used to study the impact of glutamine supplementation at three levels (0%, 1%…
The study evaluated the effect of essential oils from lavender (Lavandula stoaches) (LEO), on growth performance, carcass quality and antioxidant status of broilers. Three nutritionally adequate diets were composed with the addition of LEO at 0, 24, and 48 mg/kg…
The present study was conducted with 288 one-day-old mixed broiler chicks (Ross 308) to investigate the effects of dietary supplementation with various levels of turmeric powder on blood constituents and antioxidant activity. The chicks were randomly assigned to eight dietary…
This study was conducted to investigate the effects of different levels of coriander (Coriandrum sativum) seed powder and extract on the performance and carcass characteristics of broiler chickens. A total of 420 day-old broiler chicks (Ross 308) were allocated randomly…
In this study, performance and carcass characteristics of slow-growing broiler chicks, reared in organic or conventional systems, and fed a diet with an essential oil mixture (EOM, 48 mg/kg diet), were evaluated in the autumn and spring seasons. The rearing…
There are increasing concerns about the impact of agriculture and livestock production on the environment. In this the greenhouse gas emissions (GHG) from South African pigs, ostriches, horses, donkeys, mules and poultry were calculated, using 2010 production data on a…
