Oral Administration of at Early Gestation Modulates Litter Size and the Expression of Inhibin, Insulin, IGF-I, CO Q10, and BMP-15 in Ewes Induced for Twinning.

Gestation in sheep necessitates the support of nutrients to avoid early embryonic mortalities. Therefore, this study investigates the effects of supplementing either L-arginine or Spirulina alga in the first trimester on the pregnancy rate, litter size, inhibin, insulin, IGF-I, CO Q10, and bone morphogenetic peptide 15 (BMP15) in maternal circulation. Animals were offered barley (500 g/head/day, 14% CP), alfalfa hay (1 kg/head/day, 12% CP), clean water, and balanced salt block licks as free choices.

Expression of Hormones, Cytokines, and Antioxidants in Heat-Stressed Subfertile Female Dromedaries.

The prevailing hot climate imposes heavy burdens on the productivity of the camel, goat, and sheep herds raised in the Gulf desert. Due to the lack of a reliable indicator for the various subfertility statuses in camel females, this study aimed to investigate the expression of inhibin, TGFά, ILß, FSH, sex and metabolic hormones, and antioxidants for the fertility status in camel females. Eighty-two subfertile and five fertile females were admitted to the university clinic with the complaint of repeat breeding with failed conception.

Spirulina Supplementation to the Semen Extender Influences the Quality and Antioxidant Parameters of Chilled or Cryopreserved Arabian Stallion Spermatozoa.

The present study attempted to investigate the effect of various concentrations of spirulina platensis additions to the semen extender on Arabian stallion spermatozoa quality. Semen samples were collected with artificial vagina from five fertile stallions and diluted with an extender containing spirulina (2, 4, 6, and 8 mg/100 mL) or without spirulina (control). Aliquots of diluted semen were cooled (5°C, 90 minutes) and frozen (-196°C, 7 days), then physical traits of thawed spermatozoa were examined.

Fifteen lambs (av. BW, 22.

Consequences of twinning induction to ewes by a recombinant human follicle-stimulating hormone compared with pituitary-derived porcine follicle-stimulating hormone on follicular dynamics, maternal biochemical attributes, and neonatal traits.

Aim: The aim of this study was to investigate the effectiveness of using recombinant human follicle-stimulating hormone (FSH) compared with pituitary-derived porcine FSH given as one dose or multiple doses on the neonatal traits, follicular dynamics, and maternal blood biochemical constituents in ewes.

Materials And Methods: A 3×2 factorial arrangement was designed utilizing 60 adults ewes to test the effects of using two sources of FSH ( vs) in addition to control, either given as a single total dose or six descending doses to provoke twinning. Six treatments (T) were tested (n=10 ewes/T).

Involvement of Quebracho tannins in diet alters productive and reproductive efficiency of postpartum buffalo cows.

This study was conducted to investigate the effects of 10 weeks supplementation of Quebracho tannins (QT; 0 [control], 100 [QT] or 200 g/[cow·d] [QT]) to 30 multiparous postpartum buffalo cows (10 cows per group) on milk yield and composition, blood metabolites and reproductive performance. Supplementation of QT had no significant effect on milk yield, whereas QT decreased ( < 0.05) this trait.

Consolidating probiotic with dandelion, coriander and date palm seeds extracts against mercury neurotoxicity and for maintaining normal testosterone levels in male rats.

Objective: Heavy metals are major elements polluting our universe. The inhalation, ingestion or even contacting human body with these elements results in huge health problems. The most common pollutant in our surrounding is mercury.

Azoospermia in male dromedary: Clinical findings, testicular biopsy, serum follicle stimulating hormone and seminal biomarkers.

Azoospermia is not an uncommon infertility problem in the male dromedary (Camelus dromedarius). Azoospermia was investigated via clinical findings, testicular biopsy as well as the evaluation of follicle stimulating hormone (FSH), concentration of camel testis protein (TEX101) and camel epididymis-specific extracellular matrix protein (ECM1) in seminal fluids. Azoospermic male camels (AZOO group, n = 28) that had been detected to be infertile as a result of lack of resulting pregnancies after repeated mating's for at least one season were included in this study.
