“…The ban on antibiotics as growth promoters in animal feeds (1 January 2006) has resulted in an increase in demand for finding alternatives that could replace them. Over the last decade, a significant increase in studies on the use of natural plant extracts as antimicrobial growth promoters in animal feeds have been observed [ 1 ]. Essential oils (EOs) are volatile, aromatic plant extracts, with several antimicrobial properties such as degradation of bacterial cell walls, increase in membrane permeability, coagulation of cytoplasm, and destruction of cytoplasmic membranes and membrane proteins [ 2 , 3 , 4 , 5 , 6 , 7 ].…”

Essential oils (EOs) are generally considered as an alternative to antibiotics because of their antimicrobial properties. Despite their vast variety, their volatile nature poses hindrance on their use in animal feeds, which demands a high degree of stability. This study aimed at testing the susceptibility of three EOs (mixtures of EOs based on cinnamaldehyde, named Olistat-Cyn, Olistat-G, and Olistat-P) in two forms (free: fEOs; and microencapsulated: mEOs) to in vitro ruminal degradation using the Ankom DaisyII technique. The microencapsulation was made using a matrix based on vegetable hydrogenated fatty acids. Compared to the fEOs, which were completely degraded within 48 h of in vitro incubation, the mEOs showed a low ruminal disappearance. In comparison to the fermentation profile at 0 h, Olistat-G significantly decreased the pH and the total protozoa number after 48 h, while the total VFAs increased. However, the other EOs (Olistat-Cyn and Olistat-P) had no effect on the rumen fermentation parameters. In conclusion, the protection of EOs from ruminal degradation by microencapsulation was found to be very effective to ensure rumen by-pass. Among the EOs, Olistat-G was capable of changing rumen fermentation, potentially reducing methane emissions.

“…Currently, there are several commercially available EO products which are given to ruminants, including dairy animals, in many parts of the world [ 7 , 45 , 46 , 47 ]. In general, essential oils have a positive influence when administrated with dairy sheep rations.…”

“…Feed additives such as antibiotics, hormones and other pharmaceutical substances, despite their financial benefits, have been prohibited in most countries of the world, mainly due to their potentially hazardous residues and due to the development of multi-drug resistance in bacteria [ 6 ]. The antimicrobial action of essential oils (EOs) has been known for decades and a large number of scientific studies have been carried out [ 7 ]. Recent scientific interest has focused on the addition of essential oils to ruminant nutrition in order to improve nutrient utilization efficiency and dairy product quality.…”

The effect of a diet supplemented with a novel cornus extract, enriched with essential oils of oregano and thyme, on the performance of Chios cross-bred dairy sheep was investigated during the summer period. The plant extracts were prepared using a “green” method based on aqueous extraction. A total of 45 lactating ewes were allocated into three equal groups in a randomized block design. The three groups were fed the same feed allowance, roughage based on Lucerne hay and wheat straw and a concentrate based on cereals and oil cakes (the control diet). The diet of two groups was fortified with cornus extract, with or without oregano and thyme essential oils, at a level 0.515 g of plant extract/essential oils per kg of concentrate. Individual milk yield was recorded weekly and feed refusals were recorded on a pen basis daily, during a six-week period of lactation. Milk samples were analyzed for the chemical composition of protein, fat, lactose and solids-not-fat constituents, somatic cell counts and total viable bacteria counts. Moreover, the milk of each group was used for yoghurt and Feta cheese production. The lipid oxidative stability, protein carbonyl content and fatty acid composition of milk, yoghurt and cheese samples were also evaluated. The results showed that the incorporation of novel plant extracts and essential oils increased the milk production per ewe. Dietary supplementation with cornus extracts and essential oils lowered lipid and protein oxidation in milk, yoghurt and cheese samples, compared to the control. However, diet supplementation with herbal extracts did not affect the fatty acid profile in milk, cheese and yoghurt or the serum biochemical parameters. In conclusion, dietary supplementation with cornus in combination with oregano and thyme has the potential to improve feed utilization and the performance of high-yield dairy Chios cross-bred ewes reared under heat stress.

The problem of increasing of livestock and poultry has led scientists to look for measures to improve productivity and reduce costs. One way to solve this problem is to use balancing supplements in the feeding. The study of feeding by protein-vitamin-mineral feed supplement “Efiprot” was carried out on three groups of young white pigs, 12 heads in each group. The experiment consisted of leveling of 15 and a basic period of 127 days. During the rearing period, the animals consumed the feed according to the growth phases, increasing the amount from 1 kg/head (8–15 kg of live weight), up to 1.5 kg/head per day (15–35 kg of live weight) and from 2 kg/head (35–65 kg of live weight) and up to 2.5 kg/head. per day (65–110 kg of live weight). While using in feeding of young pigs of PVMS “Efiprot”, a positive productive effect was obtained. Thus, when introduced to the diet of the tested yong pig the PVMS, the average daily growth of animals has increased by 33–58 g. Accordingly, has increased the final live weight of the animals by 4.05–7.18 kg against the control level. Due to the result of the studies, carrying out the control slaughter, it was found that feeding of the protein-vitamin-mineral supplement “Efiprot” for young pigs on rearing does not have a probable effect on the weight of the stomach, but causes changes in the thickness of the wall of the cardiac zone by 0.24 mm (2.75 %), and reducing the wall thickness relative to the control by 1.04 mm (11.91 %). In the fundus zone of the stomach, there is a tendency to thicken the walls due to the mucous and sere-muscular membranes by 0.36 mm (6.75 %) and 0.35 mm (6.56 %). In the study of the pyloric zone, the thickness of the walls was decreased by 0.46 mm (3.13 %) and 0.73 mm (4.97 %) compared to the control group.The reaction of the intestine to feeding of “Efiprot” to young pigs is caused by an increase in weight and length of 0.06 – 0.2 kg and 0.5 m – 0.83 m. Also it is shown a slight decrease in the thickness of the hollow shell by 0.5 mm (18.3 %) in the second group of animals 0.21 mm (7.69 %). A significant difference was found in the structure of the colon of experimental animals, where there was an increase in wall thickness in the first group by 0.13 mm (5.75 %) and a decrease in the second group by 0.16 mm (7.07 %).
