Abstract

This study aimed at identifying the effects of propolis and honeybee pollen (HBP) on growth performance, fecundity and some hematological indices of liver and kidney functions of Nile tilapia ''Oreochromis niloticus'' supplemented with 2.5% of propolis or HBP in diet for 21 days. The results showed that dietary propolis or HBP significantly (P<0.05) improved Specific Growth Rate (SGR), Average Daily Gain (ADG) and Feed Efficiency ratio (FER). Propolis significantly (P<0.0001) increased the percentage of O. niloticus with ripened eggs. Microscopically, the ovaries were seen to contain a large number of oocytes >4 mm in the treated groups. In male, HBP feeding significantly (P<0.05) increased testicular weight, gonadosomatic index and improved the semen quality. Nevertheless, propolis treated males showed a significant (P<0.05) increase in head abnormalities among all groups. Sections from the testes of HBP-fed group appeared highly active and showed accumulated sperms in seminiferous tubules. Propolis or HBP significantly (P<0.001) decreased the serum ALT. Concluding that, supplementation of fish diet with either propolis or honeybee pollen is promising a beneficial effect for fisheries due to its potential improving effect on the growth rate and fecundity and preserving some biochemical indices of liver and kidney functions of O. niloticus.

Evaluation of the therapeutic effect of propolis on Fasciola gigantica and Clostridium novyi type B infections in sheep

“…In the untreated control group we observed short-term diarrhea, which leads to a loss of body weight. These results confirm that propolis supplements improved growth and carcass yield (Seven et al, 2008;Abbass et al, 2012;Kupczyñski et al, 2012;Morsy et al, 2013). The increased weights may be due to the anabolic activity of propolis.…”

New emerging fields of application of propolis

“…The test subjects have been different animal species, including poultry (chickens, laying hens, quails) [35][36][37][38][39][40][41][42][43][44][45][46][47][48], lambs [49,50], cattle [51], sheep [52], pigs [53], and fish: sea bass [54], rainbow trout [55][56][57], Nile tilapia [58][59][60], and carp [61] (Table 2). In general, propolis has a positive effect on the biochemical parameters, growth and productivity of the test animals, and is regarded as a possible alternative to antibiotics in animal feed.…”

Honey Bee Pollen in Meagre (Argyrosomus regius) Juvenile Diets: Effects on Growth, Diet Digestibility, Intestinal Traits, and Biochemical Markers Related to Health and Stress

“…The introduction of HBP in freshwater fish diets has led to improved growth and immune status [17], increase in the number of phagocytic cells, (i.e., neutrophils and monocytes), and reduction of the mortality caused by Aeromonas hydrophila in Nile tilapia (Oreochromis niloticus) [8].…”
