The influence of the protein content of the diet on glucose concentration (denoted by fluorescence intensity) and body weight was studied in the white rat. Rats of 30d of age received ad lib. a control diet containing 15% crude protein (Pl5), or a diet containing 23% crude protein (P23) or 35% crude protein (P35) and a fourth group of rats (P8) received the 8% crude protein contained diet. Afte...

Ram seminal plasma increases the fertility of frozen-thawed ram spermatozoa deposited into the cervix. The aim of the current study was to compare the effect of ram seminal plasma to that of bull seminal plasma, dog prostatic fluid, protein-free TALP TrilEq (Triladyl with 0.5 mt of Equex STM paste added to each 100 mt) and heat-treated skim milk on longevity and percentages of progressively mot...

Nutrition has an important impact on the reproductive performance of dairy and beef cattle. Energy is the major nutrient required by adult cattle. Inadequate energy intake has a detrimental effect on reproductive activity of female bovine. Cows under negative energy balance have lowered plasma glucose, insulin and IGF-I, reduced peak frequency of LH pulses, lowered plasma progesterone, and impa...

Prostate Secretory Protein of 94 amino acids (PSP94) is one of the major proteins present in the human seminal plasma. Though several functions have been predicted for this protein, its exact role either in sperm function or in prostate pathophysiology has not been clearly defined. Attempts to understand the mechanism of action of PSP94 has led to the search for its probable binding partners. T...

BACKGROUND The human seminal fluid is a complex body fluid. It is not known how many proteins are expressed in the seminal plasma; however in analog with the blood it is possible up to 10,000 proteins are expressed in the seminal plasma. The human seminal fluid is a rich source of potential biomarkers for male infertility and reproduction disorder. METHODS In this review, the ongoing list of ...

Seminal plasma is comprised of the extracellular sperm milieu from spermatogenesis in the testes, through to maturation in the epididymis, as well as secretions from the accessory sex glands. Consisting primarily of proteins, this substance has a multitude of functions in mammalian reproduction. Seminal plasma influences sperm physiology, success of semen freezing, migration of spermatozoa thro...

Ovulation in camelids is induced by an unidentified protein in the seminal plasma of the male termed 'ovulation-inducing factor'. This protein has been reported to be a 14-kDa protein under reducing conditions, which, when purified from seminal plasma, induces ovulation in llamas. The identification of this protein and investigation of its potential to induce ovulation in camelids may aid the d...

One of the non-classical human leukocyte antigen (HLA) class Ib proteins, HLA-G, is believed to exert important immunoregulatory functions, especially during pregnancy. The presence of HLA protein in paternal seminal fluid has been suggested to have an influence on the risk of developing pre-eclampsia. We have investigated whether HLA-G protein is present in human seminal plasma and in differen...

l- carnitine has been recognized as a new and important dietary supplementation, essential for human and animal nutrition. this study was conducted to evaluate the use of dietary l- carnitine supplementation and its effects on the growth (body final weight, daily growth rate (dgr), feed efficiency (fe), feed conversion ratio (fcr), daily feed intake  (dfi), protein efficiency ratio (per), lipid...

this experiment was conducted to evaluate the addition of seminal plasma to coated spermatozoa after 72 h. semen was collected from four taleshi rams by artificial vagina. to prepare coated spermatozoa, semen was collected in tube containing tris-fructose-15% egg yolk. after initial evaluation, the samples were mixed and centrifuged. after removal of supernatant and dilution, samples were divid...
