Animal feed: Garlic Properties
Garlic has been used since ancient times as a natural remedy to prevent and treat various diseases.
At the end of the 20th century, great advances were seen in various areas of the animal husbandry, but they had serious consequences on the consumer confidence.
In Europe, there is a growing tendency to reject the use of antimicrobials or antibiotics, which has led to the appearance of several alternative strategies, including the use of natural plant extracts and their intrinsic active substances.
Although there is a wide range of herbal and oil species available for inclusion in animal feed, the one that is receiving more attention is garlic. Garlic (Allium sativum L.) is a plant native from Central Asia and has been widely used as food since ancient times, acquiring a reputation as a therapeutic agent in the folklore of many cultures. It has been used as a natural remedy to prevent and treat various diseases. Multiple studies have shown that garlic has antibacterial, antifungal and antiviral properties, in addition, it can increase the palatability of food and, therefore, food consumption.
The effects of garlic have been associated with its high content in sulfuric components such as alliin, allicin, ajoene, diallyl disulfide and S-allylcysteine, among others. Allicin has been identified as the main active component of garlic.
Among the different properties associated with the use of garlic in animal feed are the following:
The first to describe the microbiocidal effects of garlic juice was Louis Pasteur. Garlic has a broad spectrum of activity, against gram positives and gram negatives, and also anthelmintic properties. It has been used as a natural alternative to growth-promoting antibiotics.
It has been proved that the addition of garlic extract modifies the structure of the intestinal wall, increasing the height of intestinal villi and the depth of the crypts of the intestine epithelium.
Food utilization is proportional to the surface of the epithelium that is in contact with the intestinal content, and it is therefore related to the integrity of the tissue. Higher height of intestinal villi and greater crypts depth of mean there is a greater contact surface that will result in better absorption of nutrients.
Improves intestinal absorption of calcium
Garlic extract promotes intestinal absorption of calcium, as it modulates some of the enzymes involved, such as intestinal alkaline phosphatase and calcium-activated ATPase, so it can be used, for example, in the feeding of layers and also as a replacement of the enzyme phytase.
In addition to these properties, garlicâ€™s immunostimulant and antioxidant properties have been observed various trials, as well as a hypocholesterolemic effect.
