Xylo oligosaccharide & Fructo oligosaccharide are the inner portion of yeast cell wall (naturall substances),
show many benefits when added to poultry feed as it has 3 main actions which is:
- Pathogen binding activities.
- Alteration of intestinal microbial
- Alteration of immune function. these functions leads to decrease losses from disease,
- improvemed feed conversion rate, improved health status, improvsd weight gain,
- stimulating the immune system & increase microflora in the gut.
Effects of Bacillus Subtilis:
- – Improve fertility and hatchability in breeders
- – Improve the semen quality in male birds
- – Increase the egg production
- – Better FCR and weight gain
- – Reduce post antibiotic stress
- – Decrease disease outbreak by improving body resistance
- – Natural feed additives, nonchemical, non-antibiotic
- – Antibacterial, Antiviral and Anticancer actions
Allicin (Garlic Extract):
that enhances immune functions and has antibacterial, antifungal and antivirus activities.
It is known to prevent platelet aggregation.
Medicinal properties of garlic rely upon organosulfur compounds mostly derived from alliin.
Organosulfur compounds originating from garlic inhibit carcinogen activation, boost phase 2 detoxifying processes.
In addition to its documented effect upon growth performance, immunostimulant and anticoccidial in broilers
Curcumin:
acts as an antioxidant, antimutagenic, anti-inflammatory and antimicrobial agent and protect liver against a variety of toxicants.
– Nowadays, alternative feed supplements enhancing bird health are sought by poultry producers.
Among different herbs and supplements, turmeric (Curcuma longa L.),
which contains bioactive secondary metabolites as curcuminoids, has been successfully used as a suitable feed supplement
for poultry. It induces a wide range of positive actions in birds, namely:
1. improvement of several haematological and biochemical indicators,
2. increase of antibody titers after vaccination (e.g., against Newcastle disease),
3. diminishment of heat stress by different mechanisms,
4. prevention from harmful effects of aflatoxins consumed together with diet,
5. increase of antioxidant activity of several organs (e.g., spleen),
6. decrease in some potentially pathogenic bacteria counts, i.e. Escherichia coli, in the ileal content of the farmed laying hens.
The aim of this review is to describe and analyse the use of turmeric as feed supplement for birds and its influence on animal health.
fenugreek
– Antimicrobial Effects: The seeds of the fenugreek herb possess toxic oils,
and other constituents of the fenugreek leaf have been shown to be toxic to bacteria,
parasites and fungi. A 2007 issue of Current Science journal noted the antifungal properties of fenugreek.
The research attempted to clone the substance defensins which are native to plants such as fenugreek to
test their effects in the petri dish. The defensins protect the plant from fungi which was extracted from leaf tissue.
– The 2004 Asia Pacific Journal of Clinical Nutrition article also noted that germination or sprouting of fenugreek
seeds increased their antioxidant profile and antimicrobial activity against H-pylori. Finally, a 2006 African Journal of
Biotechnology article compared the effectiveness of fenugreek against two common pathogenic bacteria.
Fenugreek was found to strongly inhibit the growth of Staphylococcus aureausand Pseudomonus aeruginosa in a petri dish .
– Antitumor activity: The Pretreatment with a fenugreek extract was found to enhance macrophage cell counts in rats.
When these rats were subsequently inoculated with tumor cells, tumor cell growth was inhibited .
– In 2008 Palaniswam al studied the In vitro anti-plasmodial activity of Trigonella foenum–graecum L. In vitro anti-plasmodial assay
of the extracted fractions of fenugreek leaves was carried out using chloroquine sensitive
and resistant Plasmodium falciparum isolates. Schizont maturation inhibition assay was used to analyze the potential of the extracts.
