“…Similarly, the findings of Galal et al (2008) showed that supplementing propolis at the levels of 100 and 150 mg propolis/kg diet significantly reduced AST and ALT concentration than those of the control group. Contrarily, Hashema et al (2013) found no significant effect due to propolis supplementation on AST and ALT in broilers.…”

One hundred and twenty eight, 28-weeks-old Lohmann LSL hybrid layers were used in this experiment, which lasted 12 weeks to investigate the effect of propolis supplementation on the productive performance, egg quality traits and haematological variables of laying hens. All hens were randomly classified into four equal experimental groups, eight replicates (4 birds/each). Hens in group 1 were fed on a commercial diet and considered as control group, while those in groups 2, 3 and 4 were fed on the same commercial diet and supplemented with 250, 500 and 1000 mg propolis/kg diet. The obtained results revealed that daily feed consumption/hen increased insignificantly with increasing propolis level than that of the control group. Regarding the means of egg mass and egg production rate, it was observed that the laying hens fed diets containing 250 and 1000 mg propolis/kg significantly (p < 0.05) produced more and heaver egg in comparison with control group. External egg quality traits have not affected with increasing the level of propolis, while eggshell weight was significantly (p < 0.05) increased. The internal egg quality traits except albumen and yolk percentages increased significantly (p < 0.05) with increasing propolis level for treated hens as compared to those in the control. Concerning the haematological parameters, the results showed that the levels of total protein and globulin increased significantly with increasing propolis level, while cholesterol and liver enzymes were significantly decreased (p < 0.05). Heterophils count of hens in the treated groups significantly decreased, whereas the lymphocyte count significantly increased, resulting in a decreased H/L ratio than that of the control group. Thus, it could be concluded that the supplementation of 250 mg propolis/kg diet is highly recommended to improving egg production, blood constituent and haematological parameters of the commercial laying hens.

“…This vitamin functions as anti-sterility function and its shortage results in the degeneration of germinal epithelium occurs. The continuous and small doses of this vitamin lead to improve the semen characteristics in domestic animals [39,45,46]. Youself also found that this vitamin has ameliorative effects on oxidative stress with dose of 2 IU/kg in pyrethroid induced toxicity (Figure 2).…”

“…For males, it has been demonstrated that propolis provides protection against infertility by improving sperm production, motility, count and quality, and increased the process of steroidogenesis and hence testosterone production. Hashem et al, (2013) observed that the dietary manipulation of ethanolic extract of the Egyptian propolis (150 mg/kg diet) offers an easily applicable measure for improving sexual activity and semen quality (high sperm concentration and viability) and testosterone concentrations of rabbit bucks during hot seasons in the subtropics. This sexual activity improvement was associated with the increasing of high density lipoprotein that has several pivotal biological functions including (1) facilitating transportation of hydrophobic lipid molecules like cholesterol and triglycerides to move within the water-based blood stream; (2) transporting cholesterol into steroidogenic organs such as the adrenal gland, ovary, and testis; and (3) removing the excess molecules of low density lipoprotein (LDL) through the liver (Hashem et al, 2013).…”

ropolis is a resinous substance collected by honeybees from buds and leaves of trees and plants, mixing with pollen as well as enzymes secreted by bees. Propolis is known to be active against gram positive bacteria, viruses, fungi, oxidants, inflammation, tumors, and parasites thus recently it have been considered among the natural feed alternative to antibiotics in ruminant diets. Propolis extracts were found to have a promising effect on decreasing energy lost as methane and total N losses, the most significant inefficiencies remaining in ruminant production systems that may limit production performance and contribute to the release of pollutants to the environment. However, these effects are divers among propolis types. In vitro, however alamo and green propolis were extracted with the same method, but alamo propolis presented a higher efficiency to reduce methane production than the green one and both of them had no effect on ammonia concentrations, gas production and ruminal degradability. Red and brown propolis extracted similarly had very different compositions and seemed to act in a similar way in modifying the ruminal degradation of nutrients and mitigating methane formation. In vivo studies involving ruminant metabolism, divers' effects of different propolis samples have been found on the total digestibility, ruminal digestibility, intestinal digestibility. However, similar effects were observed with the different propolis studies on reducing ammonia production and the number of ruminal ciliate protozoa in buffaloes and dairy cows, as well as in in viro trails. The inhibitory activity of different propolis samples were observed on both mature and immature hepatic worms, and intestinal eggs. Red propolis had good impact on general ewe health during critical periods such as flushing and found to have high efficacy against the gastro intestinal helminthiasis. Similar findings in growth performance in a study on feedlot lambs fed a diet supplemented with brown propolis, but the green propolis was not efficient. Often, in most studies, the type or the chemical composition of the propolis is not even specified in publications. The biological activity of propolis may vary, together with its chemical composition, as it comprises numerous constituents together with the method of extraction and concentrations of the solvent and propolis. Thus in order to ensure the propolis quality as feed additive and to be officially accepted by major health agencies, propolis requires a chemical standardization and identify the active component(s) of propolis and subsequently analyze these in commercial batches.
