Fetal uninephrectomy (uni-x) results in hypertension at a later age in female than male sheep. We hypothesized that dysregulation of tubular sodium handling contributes to the reduced ability to regulate extracellular fluid (ECF) homeostasis in older females born with a congenital nephron deficit. Following renal excretory balance studies, the response to inhibition of the Na(+)K(+)2Cl(-) cotra...

Abstract Fetal microchimerism has been detected in maternal tissues of humans and rodents during after pregnancy. Studies focusing on fetal DNA transfer to domestic animals are limited, especially sheep. ram was observed the circulation pregnancy, but it is not known if this chimerism persists soft parturition. The objectives exploratory study were to: 1) determine male detectable mature ewes p...

Background and Aim: Healthy meat production is an important aspect of increasing sheep productivity. This study aimed to examine the influence protected kapok seed oil (KSO) in combination with choline chloride (CC) on feed utilization, lipid status, performance thin-tailed sheep. Materials Methods: Thirty male (approximately 6 months old, average body weight 12.59 ± 1.48 kg) were divided into ...

background: testis tissue xenografting and the resultant sperm in a xenograft may provide a unique approach to rescue the genetic material of males that die prematurely and is a model for the study of human spermatogenesis and can represent an alternative approach for fertility preservation in cancer patients. this study was aimed to evaluate the xenogenic dog sperm in formation of male pronucl...

This study was conducted to evaluate the effects of providing shade on growth performance, welfare, and meat quality of grazing sheep under high ambient temperature. A total of 120 healthy male Ujumqin wool sheep (a local breed; BW = 18.7 ± 1.27 kg; 14 wk old) were randomly and equally divided into shaded and unshaded treatments with 3 pens per treatment. Sheep were grazed on an unshaded pastur...

ABSTRACT The objective of this study was to evaluate the effect replacing Tifton 85 hay with maniçoba in diets based on spineless cactus nutrient intake and digestibility, ingestive behaviour ruminal parameters confined sheep. In order do this, eight male sheep cannulae were used, distributed across four levels (0, 333, 666 1.000 g kg-1 dry matter) replacement a double Latin square experimental...

sarcocystis is one of the most prevalent parasites of domestic ruminants worldwide. this study was aimed to determine prevalence of sarcocystis infection and molecular discrimination of sarcocystis gigantea and sarcocystis medusiformis infecting domestic sheep. tissue samples from 638 sheep slaughtered at urmia abattoir were randomly collected from february 2011 to january 2012. genomic dna ext...

histomorphologic and histomorphometric studies on the pancreas of mehraban male sheep were done in four age groups: fetus, neonate, young adult and old age in this respect, we used special stainings, light microscope and ocular micrometer. the results showed that the smooth muscles were absent in capsule. the tubular portion of exocrine pancreas was more prominent. neuroinsular complex and beta...

Infection by Trypanosoma vivax and other African trypanosomes plays an important role in reproductive disorders in male and female livestock. Outbreaks of T. vivax in the semi-arid region of northeastern Brazil are characterized by wasting disease in cattle, sheep and goats with hematological, cardiac and nervous compromises in addition to reproductive failures. Similar to reports from Africa, ...

A case of ovine listeriosis was examined in a flock of sheep. The index case was a male lamb, which was part of a flock of 85 sheep located in central Iowa. Because the sheep were raised on a premise where soybean sprouts were also cultivated for the organic foods market, the potential of a public health concern was addressed. To identify the source of contaminations, clinical and environmental...
