Background: Are dietary patterns, substantiated by biomarkers, associated with semen quality? Materials and Methods: In 161 men of subfertile couples undergoing in vitro fertilization treatment in a tertiary referral clinic in Rotterdam, the Netherlands, we assessed nutrient intakes and performed principal component factor analysis to identify dietary patterns. Total homocysteine (tHcy), folate...

World Health Organization (WHO) defines infertility as the inability of a sexually active, non-contraceptive couple to achieve pregnancy in 1 year (1). Overall, the worldwide incidence is about 15 % and a male factor is responsible in 20–50% of cases (2). Medical history, physical examination and semen analysis remain...

Seven bermudagrass hays were fed to growing steers to determine the relationship between average daily gain (ADO) and Quality Index (QI). Voluntary intake and digestibility were measured with cattle and sheep, respectively. The range in ADG was from -.3 to 1.7 lb/d, and QI ranged from .9 to1.9. The correlation between ADG and QI was quite high (r = .92). For growing steers, QI is a valid expres...

Four years of grazing trials were conducted with Brassica forages to evaluate their chemical composition and effect on ADG of fattening lambs and breeding ewes in late fall. Brassicas tested included kales (Brassica oleracea L. var. acephala DC), turnips (B. rapa L.), and a chinese cabbage hybrid (B. rapa L. x B. pekinensis [Lour.] Rupr.). Daily gains of lambs varied widely among years (19 to 3...

Estimated breeding value was calculated based on individual phenotype (SP), an index of individual phenotype and full- and half-sib family averages (SI), or Best Linear Unbiased Prediction (BLUP). Traits considered were litter size (LS), backfat (BF), and ADG. Estimated breeding values were calculated using all data and after deletion of the poorest 5, 10, 15, or 20% of the records for BF and A...

Abstract Study question In men with Raised Sperm DNA Fragmentation Index (DFI), Would advance sperm preparation techniques at Intra-Cytoplasmic Injection (ICSI) alter embryo euploidy status? Summary answer raised DFI, use of selection are safe and do not appear to ploidy status the embryos What is known already MACS (Magnetic Activated Cell Sorting), Microfluidic Sorting (MF), surgically retrie...

BACKGROUND The study evaluated the effect of New Neonatal Porcine Diarrhoea Syndrome (NNPDS) on average daily gain (ADG) and mortality and described the clinical manifestations in four herds suffering from the syndrome. NNPDS is a diarrhoeic syndrome affecting piglets within the first week of life, which is not caused by enterotoxigenic Escherichia coli (ETEC), Clostridium perfringens (C. perfr...

Four experiments were conducted to investigate the effects of deoxynivalenol (DON) from naturally contaminated dried distillers grains with solubles (DDGS) and the efficacy of feed additives in nursery pig diets. In Exp. 1, 180 pigs (10.3 ± 0.2 kg BW) were fed 1 of 5 diets for 21 d. Diets were 1) Positive Control (PC; < 0.5 mg/kg DON), 2) Negative Control (NC; 4 mg/kg DON), 3) NC + 0.10% Biofix...

OBJECTIVE To examine the relationship among sperm apoptosis, sperm chromatin status, and DNA ploidy in different sperm fractions. DESIGN Prospective study. SETTING Reproductive research center in a tertiary care hospital. INTERVENTION(S) Sperm prepared by density gradient were evaluated for sperm count, motility, apoptosis, and sperm chromatin assessment. MAIN OUTCOME MEASURE(S) Sperm c...

OBJECTIVE To examine sperm DNA fragmentation in semen used for assisted reproduction procedures to establish this factor's prognostic role in fertilization rate, embryo development, pregnancy rate, and outcome. DESIGN Prospective study. SETTING Department of Medicine and Biology of Reproduction of the Edouard Herriot Hospital in Lyon, France. PATIENT(S) 322 couples, divided into 88 cycles...
