Effect of flaxseed supplementation on metabolic state,endocrine profiles,body composition and reproductive performance of sows

Objective:To assess the effect of flaxseed supplementation on metabolic profile,endocrine concentrations,non-esterified fatty acids(NEFA),body composition variables,and reproductive performance of sows.Methods:All the 21 crossbred Large White Yorkshire sows were considered in the study period starting at day 1 of current farrowing when the feeding of specific supplemental ration was started until the day of subsequent farrowing(days 150-155)and were equally allocated into three groups.Group 1 served as the control group and followed their normal feeding schedule.Group 2 and group 3,in addition to their normal feeding schedule,were supplemented with flaxseed at a rate of 0.5%and 1.0%of the dry matter,respectively.Blood samples were collected 15 days prior to farrowing,on the day of farrowing(day 0),at weekly intervals until day 28 of lactation and at monthly intervals during gestation to harvest the plasma.Plasma was used to assess the metabolic and endocrine status of sows.Body weight of each sow and individual birth weight of all piglets born were measured.Results:Flaxseed supplementation led to decrease in plasma cholesterol and triglyceride levels in the supplemented groups than in the control group(P<0.05).Plasma estradiol-17βlevel was higher in group 2 than that in group 1 and 3 on day 90 of the gestation period(P<0.05).The mean plasma level of insulin-like growth factor 1 was higher in group 3 than that in group 1 and 2 both in late lactation(day 28)as well as in early gestation(day 30)(P<0.05).Plasma NEFA and weight gain were greater in sows of group 2 and 3 compared to those fed with the normal control diets(P<0.05).The proportion of pregnant sows relative to sows bred was 100.0%in group 2 and 3 and 85.7%in the control group.Piglet mortality was lower in group 2 and 3 compared to group 1(P>0.05).Conclusions:Flaxseed improves endocrine profiles,NEFA concentrations and body weight,resulting in better pregnancy rate and litter size.

Precise review of a male's infertility assessment from a men's health specialist prospective

Infertility is a pervasive issue affecting a considerable proportion of couples in their reproductive years,with a projected 10%-15% prevalence.It is characterized by the incapability to achieve conception following a year of consistent,unprotected intercourse,and its far-reaching consequences can take a profound emotional,psychological,and social toll on couples,inducing feelings of melancholy,exasperation,and anxiety.The appraisal of infertile couples'cases is a multifaceted and daunting process,necessitating a holistic understanding of the intricate underlying factors contributing to their infertility.Consequently,an individualized evaluation should be conducted,considering diverse parameters,such as the couple's medical history,age,infertility duration,and other relevant criteria.This paper will provide an in-depth overview of the current approaches utilized in the evaluation of men with infertility,including the commonly employed diagnostic tools and procedures.Enhancing our comprehension of infertility assessment and management holds the promise of helping couples achieve their ultimate desire of conceiving and enriching their overall quality of life.
