“…Moreover, growing rabbits administered royal jelly have improved their physiological conditions , while adult males have experienced reduced summer infertility under heat stress (Elnagar, 2010). Also, pregnancy rate and overall reproductive performance was improved in ewes administered royal jelly (Kridli et al, 2003;Husein and Haddad, 2006;Kridli and AlKhetib, 2006). Thus, results from this and previous studies confirm the beneficial antioxidative effect of royal jelly in reducing the incidence of apoptosis in oocytes during IVM, which was coupled with enhancing mitochondria activity.…”

Royal jelly (RJ) was supplemented to goat oocyte in vitro maturation (IVM) medium at three different concentrations (2.5, 5, and 10 mg/ml). Maturation rate, embryo cleavage, and blastocyst rate were recorded. Gene expression of apoptosis-related transcripts was investigated in matured oocytes. Percentage of oocytes that reached MII-stage was increased in RJ-treated groups compared to the control group. Glutathione (GSH) content of mature oocytes was enhanced when RJ was added to IVM medium at any supplementation compared with control. Percentage of cleaved embryos and blastocysts was higher in the RJ-treated groups at a concentration of 5 mg/ml than in the 2.5 mg/ml and control group. Total number of cells per blastocyst was not different in the control and RJtreated group at 5 mg/ml. However, number of apoptotic cells per blastocyst was higher in the control group than in the RJ-treated group at 5 mg/ml. Expression profile of Bax, and p53 was down-regulated while Bcl-2 was upregulated in oocytes treated with RJ at 5 and 10 mg/ml compared with the control group. Addition of RJ at concentrations of 5 mg/ml improved embryo production through increasing maturation rate. RJ seems to improve the IVM microenvironment by reducing expression of genes inducing apoptosis, enhancing GSH content, and reducing incidence of apoptosis in blastocysts.

“…However, continuous usage of eCG can result in the generation of antibodies that render future usage of such hormone ineffective (Bodin et al, 1997). For this reason, several studies examined the effects of replacing eCG with royal jelly (a honeybee product) on reproductive parameters in Awassi ewes (Husein and Kridli, 2002;Kridli et al, 2003;Husein and Haddad, 2006;Kridli and Al-Khetib, 2006). Results indicated that royal jelly can effectively be incorporated into estrus synchronization programs to replace eCG.…”

“…La administración del eCG puede dar como resultado la creación de anticuerpos que dan pie al uso futuro de tales hormonas ineficaces (Bodin et al, 1997). Por este motivo, varios estudios han evaluado los efectos de sustituir eCG por jalea real (un producto de las abejas) en los parámetros reproductivos de las ovejas Awassi (Husein y Kridli, 2002;Kridli et al, 2003;Husein y Haddad, 2006;Kridli y Al-Khetib, 2006). Los resultados muestran que la jalea real puede ser incorporada de forma efectiva en los programas de sincronización del estro para sustituir el eCG.…”

RESUMENJordania es un país predominantemente semiárido. La mayor parte de la tierra es incultivable y sólo se puede utilizar para el pastoreo de rumiantes pequeños. La oveja Awassi de cola gruesa es la raza nativa de ovejas en Jordania. Esta raza es popular por varias razones, tales como su adaptabilidad a ecosistemas difíciles, su producción lechera y por tener una carne con buenas características y un buen sabor. La industria ovejera en Jordania enfrenta muchos retos, el más importante es la escases de agua, que conlleva a una baja disponibilidad de forrajes y a un alza en los precios de los alimentos. A pesar de las dificultades, se realizan esfuerzos para mejorar la productividad de las ovejas Awassi mediante la selección, el cuidado veterinario, la evaluación de fuentes alternativas de alimentación y tratamientos hormonales para mejorar su fertilidad y fecundidad. Este estudio enfatiza la investigación principal llevada a cabo en ovejas Awassi en Jordania en la última década con un énfasis especial en el rendimiento reproductivo. ABSTRACTJordan is a predominantly semi arid country. Much of the land area is uncultivable and can only be used as a range for grazing small ruminants. Fat tailed Awassi is the indigenous sheep breed of Jordan. The breed is popular for many reasons such as the adaptability to harsh ecosystems, milk production ability and having favorable meat flavor and characteristics. The sheep industry in Jordan faces many challenges, the most important of which is water shortage leading to low forage availability and high feed prices. Despite such hardships, efforts are made to improve productivity of Awassi sheep through selection, veterinary care, evaluating alternative feed sources and hormonal treatments to improve fertility and fecundity. This review highlights the major research conducted on Awassi sheep in Jordan over the last decade with special emphasis on reproductive performance.

“…Há demonstrações de que a resposta ao estro e a taxa de prenhez foram melhoradas em ovelhas quando a geleia real foi administrada em conjunto com o tratamento de progesterona intravaginal (Kridli et al, 2003). Husein e Haddad (2006) verificaram que a geleia real produziu efeito semelhante aos produzidos pela gonadotrofina coriônica equina (eCG) sobre o ciclo estral de ovelhas, aumentando a expressão do estro, diminuindo o intervalo entre estros e aumentando a taxa de gestação.…”

Estudaram-se os efeitos da geleia real sobre a espermatogênese de coelhos tratados com diferentes concentrações de geleia real. Os tratamentos foram formados por três grupos: grupo-controle; grupo que recebeu 0,5mg/dia de geleia real; e grupo que recebeu 1,0mg/dia de geleia real. O estudo envolveu a morfometria testicular. Não houve diferença entre os tratamentos quanto aos pesos corporal (T1=3,20±0,19kg, T2=2,96±0,30kg e T3=3,21±0,37kg) e gonadal (T1=2,36±0,33g, T2=2,53±0,33g e T3=2,64±0,39g) e quanto aos índices gonadossomático (T1=0,15±0,02%, T2=0,17±0,03% e T3=0,16±0,02%) e tubulossomático (T1=0,06±0,01%; T2=0,07±0,01% e T3=0,06±0,01%). O diâmetro médio dos túbulos seminíferos (T1=225,95±13,27µm, T2=239,68±21,50µm e T3=231,57±15,94µm), a altura do epitélio seminífero (T1=66,05±5,37µm, T2= 73,47±9,11µm e T3=63,34±4,79µm) e o comprimento de túbulos seminíferos por testículo (T1=46,63±13,44m, T2=43,58±12,17m e T3=46,96±9,54m) e por grama de testículo (T1=19,50±2,68m, T2=17,12±3,91m e T3=17,78±1,98m) não diferiram entre tratamentos. Conclui-se que a suplementação com geleia real, nas doses utilizadas, não altera as características testiculares avaliadas.
