Industrial cities are a particularly dynamic element of nineteenth century Walloon demography. The new slightly hybrid urban model, grown from small rural communities but which never looked like classical cities, was characterised by a very quick demographic growth, resulting from a high number of births and a relatively low mortality together with a relatively high in-migration (Eggerickx, 199...

The data on the role of consanguinity in male infertility are scarce. The presence of systematic sperm defects in consanguineous respect to non-consanguineous population was demonstrated. Systematic defects are characterized by a specific alteration present in sperm for the whole life of the carrier. This study was aimed at exploring the sperm quality in selected infertile consanguineous patien...

Guidelines for the clinical management of obese, reproductive age women with reduced fertility in the USA are limited. Clinical professional organizations have yet to publish practice guidelines on this topic. Thus, treatment decisions are made at the provider and/or clinic level and the variation in clinic policy regarding fertility treatment for obese women is not readily available. Globally,...

Body condition score (BCS) records of primiparous Holstein cows were analyzed both as a single measure per animal and as repeated measures per sire of cow. The former resulted in a single, average, genetic evaluation for each sire, and the latter resulted in separate genetic evaluations per day of lactation. Repeated measure analysis yielded genetic correlations of less than unity between days ...

This paper, with No.22 State Farm, Agricultural Division No.2, XPCC as the example and under support of GIS, takes cultivated land plot as the evaluation unit and chooses 13 influence factors from five aspects of nutrient of cultivation layer, physical and chemical properties of cultivation layer, soil management, climate conditions and obstacle factor to establish desert oasis cultivated land ...

Background: It is assumed in polycystic ovary syndrome (PCOS) that follicular development, maturation, ovulation and implantation are impaired due to hormonal imbalance and vascular impairment of the ovarian and uterine vasculatures. The mechanism of action of laparoscopic ovarian drilling (LOD) is largely unexplained. To date, only limited studies have been conducted utilizing 3D ultrasonograp...

The objective of this study was to estimate the heritability of a number of traditional and endocrine fertility traits in addition to d-56 predicted milk yield (MY56), and the genetic and phenotypic correlations between these traits. Various fixed effects such as season, year, herd, lactation number, diet, percentage Holstein (PCH) of the cow, and occurrence of uterine infection (UI), dystocia ...

22 Introduction/Purpose. Exercise improves health but few data are available regarding benefits of 23 exercise in offspring exposed to developmental programming. There is currently a worldwide 24 epidemic of obesity. Obesity in pregnant women predisposes offspring to obesity. Maternal 25 obesity has well documented effects on offspring reproduction. Few studies address ability of 26 offspring e...

The aim of study was to determine the relationships between morphological characteristics roosters and fertility in broiler breeders at different age periods. A total 48 480 hens Ross 308 breeder were used. body weight, comb width length, wattle tarsus length measured for 42, 53 weeks age. 1500 eggs incubated 37.7 °C 50-55% relative humidity 18 d, then 36.6 60% 3 d. effect on index (P=0.002), (...
