“…The antigenotoxicity and genotoxicity as well as antiestrogenic and estrogenic activity of Cystus incanus L. and Salix alba L. of BP and its processed extracts in human and yeast cells were tested, and it was found that they were neither estrogenic nor genotoxic and able to reduce the damage of chromosome induced by the used cancer drugs, thus supporting their use as a chemoprotective agent ( 95 , 96 ). BP and mannan oligosaccharides improved the antioxidant status and semen quality of rabbit bucks during the Egyptian summer season ( 167 ). Studies have shown that BP individually or coupled with metformin effectively suppressed the levels of TNF-α, Ki67, and NO while boosting mature follicles and P53 in polycystic ovary syndrome-treated rats ( 118 ).…”

Pollen grains are the male reproductive part of the flowering plants. It is collected by forager honey bees and mixed with their salivary secretions, enzymes, and nectar, which form fermented pollen or “bee bread” which is stored in cells of wax honeycombs. Bee pollen (BP) is a valuable apitherapeutic product and is considered a nutritional healthy food appreciated by natural medicine from ancient times. Recently, BP has been considered a beneficial food supplement and a value-added product that contains approximately 250 different bioactive components. It contains numerous beneficial elements such as Mg, Ca, Mn, K, and phenolic compounds. BP possesses strong antioxidant, anti-inflammatory, antimicrobial, antiviral, analgesic, immunostimulant, neuroprotective, anti-cancer, and hepatoprotective properties. It is used for different purposes for the welfare of mankind. Additionally, there is a growing interest in honey bee products harvesting and utilizing for many purposes as a natural remedy and nutritive function. In this review, the impacts of BP on different organisms in different ways by highlighting its apitherapeutic efficacy are described.

RESUMENLa fisiología digestiva y capacidad reproductiva hacen del conejo una especie con potencial para la producción de carne. En clima templado, su adecuado manejo reproductivo permite obtener entre 6 y 10 partos anuales con camadas de 6 y hasta 12 gazapos. En zonas tropicales, el estrés calórico disminuye su capacidad reproductiva. Las hembras presentan un incremento en la secreción de corticosteroides, modificando la secreción de la hormona liberadora de gonadotropina (GnRH), la hormona estimulante del folículo (FSH) y la hormona luteinizante (LH), disminuyendo el crecimiento y desarrollo folicular, calidad de ovocitos y la ovulación, y con ello el número de partos y tamaño de camada. En los machos se afecta la libido y la capacidad de monta. En la calidad seminal, disminuye 7.8 % el volumen, 7.7 % la concentración, 1.7 % la morfología y 5.5 % la motilidad. El objetivo del presente trabajo fue describir las estrategias utilizadas para disminuir el estrés calórico, que incluyó regular la temperatura en las instalaciones, suplementos alimenticios, cruzamiento de razas locales con razas mejoradas, desarrollo de líneas genéticas para climas tropicales, implementación de biotecnologías reproductivas como la inseminación artificial o criopreservación de semen, mejorando el comportamiento reproductivo del conejo bajo condiciones tropicales.PALABRAS CLAVE: condiciones tropicales, conejos, estrés calórico, Oryctolagus cuniculus, comportamiento reproductivo. ABSTRACTThe digestive physiology and reproductive capacity of the rabbit make it a species with potential for meat production. In a temperate climate, its adequate reproductive management allows to obtain between 6 and 10 annual litters per female with 6 up to 12 kits per litter. In tropical areas, heat stress alters metabolism and hormonal function, decreasing their reproductive capacity. In females, the main changes include an increase in the secretion of corticosteroids, modifying the secretion of gonadotropinreleasing hormone (GnRH), stimulating follicle hormone (FSH) and luteinizing hormone (LH), decreasing the growth and follicular development, oocyte quality and ovulation, and with it the number of births and size of litter. In males, libido and ability to mate are affected. In the seminal quality, a decrease of 7.8 % in volume, 7.7 % in concentration, 1.7 % in morphology and 5.5 % in motility is observed. The objective of the present work was to describe the strategies used to reduce the caloric stress. These included regulating the temperature in the facilities, supplementary food, crossing of local breeds with improved breeds, development of genetic lines for tropical climates, implementation of reproductive biotechnologies such as artificial insemination or cryopreservation of semen, improving the reproductive behavior of the rabbit under tropical conditions.
