“…While an optimal intake of BC is hypothesized to have positive effects upon reproductive outcomes both in ruminant (Arellano-Rodriguez et al 2007) and monogastric (Krammer and Aurich 2010) species, results have been contradictory, with studies reporting both positive (Kawashima et al 2009(Kawashima et al , 2012 and negative (Folman et al 1987) effects. Nonetheless, a positive relationship between BC supplementation, metabolic and endocrine status as well as reproductive outcomes has been previously proposed.…”

“…Nonetheless, a positive relationship between BC supplementation, metabolic and endocrine status as well as reproductive outcomes has been previously proposed. Short-term BC supplementation positively affected ovarian follicular development and ovulation rate in adult goats (Arellano-Rodriguez et al 2007), increased both corpus luteum diameter as well as progesterone synthesis (Arellano-Rodriguez et al 2009). Besides, short-term BC supplementation in the adult goat increased ovarian activity and enhanced serum concentrations of insulin (Meza-Herrera et al 2013a), although without increases in serum luteinizing hormone (LH) concentrations, LH-pulse or LH-area under the curve (LH-AUC) (Meza-Herrera et al 2013b).…”

(2017): Beta-carotene supplementation positively affects selected blood metabolites across time around the onset of puberty in goats. Czech J. Anim. Sci., 62, 22-31.The possible effect of beta-carotene supplementation upon peripubertal changes in serum concentrations across time for total protein (TP), urea (UR), cholesterol (CHOL), and glucose (GLU) around puberty onset was evaluated. The experiment was carried out from June to November and prepubertal goats (n = 17, 3 months old, 7/8 Saanen-Alpine, 1/8 Criollo) were randomly assigned to: (1) beta-carotene group (BC) (n = 9; 17.3 ± 1.0 kg live weight (LW), 3.3 ± 0.12 body condition score (BCS), oral supplementation with 50 mg beta-carotene per day per goat) and (2) control group (CC) (n = 8; 16.1 ± 1.0 kg LW, 3.1 ± 0.12 BCS). Serum blood samples were collected along the experiment to quantify progesterone concentrations (P4) through radioimmunoassay, while TP, UR, CHOL, and GLU through spectrophotometric analyses. No differences (P > 0.05) occurred between treatments regarding LW and BCS, and TP (67.6 ± 2.4 g/l), UR (3.8 ± 0.17 mmol/l), GLU (5.06 ± 0.09 mmol/l), and CHOL (1.62 ± 0.07 mmol/l) concentrations. However, while a treatment × time interaction occurred between treatments for TP, GLU, CHOL (P < 0.05) favouring the BC group, an increased serum UR levels occurred in the CC group. Nonetheless, such general serum metabolite profile was related neither to the age

“…Nonetheless, inconsistent results regarding the effect of BETA-supplementation upon reproductive function have been described, with negative effects [5], positive effects [6] and even no effects [7]. From a reproductive stand point, BETA-supplementation has been associated with increased steroidogenesis in both the corpus luteum and the follicular tissue [6,[8][9][10][11].…”

“…Interestingly, nutritional supplementation with a mixture of BETA, polyphenolic compounds, and probiotics demonstrated to up-regulate genes involved in both the activation of cellular gonadotropes and up-regulation of GnRH genes [23]. While the involvement nutritional supplementation as a modulator of the HPG axis has been proposed [8][9][10][11][12][13][14][15][16]20,[23][24][25], previous studies of our group have demonstrated an interesting role of BETA as a modulator not only of serum insulin [18], triiodothyronine [26], as well as the GH-IGF-1 system [6] but also upon some selected blood metabolites [27]. Building on these previous findings, we hypothesized an out-of-season positive effect of BETA supply on both ovarian function and the releasing pattern of LH across time in yearling goats; this study attempts to solve such inquires.…”

The possible out-of-season effect of beta-carotene supplementation on ovulation rate (OR), antral follicles (AFN), and total ovarian activity (TOA = OR + AFN) as related to the LH release pattern in yearling anestrous goats was evaluated. In late April, Alpine-Saanen-Nubian x Criollo goats (n = 22, 26 N) were randomly allotted to: (1) Beta-carotene (BETA; n = 10, orally supplemented with 50 mg/goat/d; 36.4 ± 1.07 kg live weight (LW), 3.5 ± 0.20 units, body condition score (BCS) or (2) Non-supplemented (CONT; n = 12, 35.2 ± 1.07 kg LW, 3.4 ± 0.2 units BCS). Upon estrus synchronization, an intensive blood sampling (6 h × 15 min) was accomplished in May for LH quantifications; response variables included (pulsatility-PULSE, time to first pulse-TTFP, amplitude-AMPL, nadir-NAD and area under the curve-AUC). Thereafter, an ultrasonography scanning was completed to assess OR and AFN. The Munro algorithm was used to quantify LH pulsatility; if significant effects of time, treatment or interaction were identified, data were compared across time. Neither LW nor BCS (p > 0.05) or even the LH (p > 0.05); PULSE (4.1 ± 0.9 pulses/6 h), NAD (0.47 ± 0.13 ng) and AUC (51.7 ± 18.6 units) differed between treatments. Nonetheless, OR (1.57 vs. 0.87 ± 0.18 units) and TOA (3.44 vs. 1.87 ± 0.45 units) escorted by a reduced TTFP (33 vs. 126 ± 31.9 min) and an increased AMPL (0.55 vs. 0.24 ± 0.9 ng), favored to the BETA supplemented group (p < 0.05), possibly through a GnRH-LH enhanced pathway and(or) a direct effect at ovarian level. Results are relevant to speed-up the out-of-season reproductive outcomes in goats while may embrace translational applications.

“…An explanation is that the response to a feed supplementation alters glucose, insulin, leptin or IGF-I and probably other metabolic hormones (Scaramuzzi et al, 2006). Arellano-Rodriguez et al, 2007;(Arellano-Rodriguez et al, 2009). Haddad et al (2005) supplemented postpartum Awassi ewes lambing in November with two levels of ruminally undegradable intake protein (RUIP) for 2 months.…”

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.
