The objective of the experiment was to determine the optimal dose of copper oxide wire particles (COWPs) to reduce infection of Haemonchus contortus in male lambs. Five to six-month-old hair breed lambs were housed on concrete and fed 450 (L; n = 25) or 675 g (H; n = 25) corn/soybean meal supplement and bermudagrass hay. In July, lambs were inoculated with 10,000 L(3) larvae (97% H. contortus; ...

The objective of this study was to investigate the effect of maintenance system as well as the effect of Se, Zn, and vitamin E supplementation of ram-lambs on the slaughter value and concentration of mineral elements in the loin muscle of lambs. The experiment was conducted on 72 Polish Merino ram-lambs divided into three groups: group C, indoor with no supplement, 19 lambs; S, indoor with supp...

objectives: it has been noted that stuttering is more prevalent in bilinguals than in monolinguals. the similarities of the languages involved have been mentioned to justify the difference between stuttering prevalence among bilingual and monolingual speakers. the aim of this study is to investigate the effect of language similarities on prevalence of stuttering among kurdish-farsi bilingual st...

the aim of this study was identification of important factors and their effects on mortality of lori-bakhtiari lambs from birth to weaning. the data set used for statistical analysis were collected from 4991 lambs born between 1370 and 1384 in flock at lori-bakhtiari sheep breeding station. data was modeled using logistic regression. mortality variable as dependent and ewe weight at mating, ewe...

RATIONALE Inhaled nitric oxide (iNO) can reverse neonatal pulmonary hypertension and bronchoconstriction and reduce proliferation of cultured arterial and airway smooth muscle cells. OBJECTIVES To see if continuous iNO from birth might reduce pulmonary vascular and respiratory tract resistance (PVR, RE) and attenuate growth of arterial and airway smooth muscle in preterm lambs with chronic lu...

In the pulmonary vasculature, cGMP levels are regulated by soluble guanylate cyclase (sGC) and phosphodiesterase 5 (PDE5). We previously reported that lambs with persistent pulmonary hypertension of the newborn (PPHN) demonstrate increased reactive oxygen species (ROS) and altered sGC and PDE5 activity, with resultant decreased cGMP. The objective of this study was to evaluate the effects of hy...

Locoweeds ( Oxytropis and Astragalus spp.) are toxic plants found on many rangelands. Preferences for locoweed are learned; livestock often initially reject the plant, but learn to eat locoweed after continued exposure. Maternal influences are important in shaping diet selection in young animals. We studied the influence of ewe consumption of locoweed on lamb selection of the plant. Twenty-four...

INTRODUCTION Factors explaining the greater susceptibility of preterm infants to severe lower respiratory infections with respiratory syncytial virus (RSV) remain poorly understood. Fetal/newborn lambs are increasingly appreciated as a model to study key elements of RSV infection in newborn infants due to similarities in lung alveolar development, immune response, and susceptibility to RSV. Pre...
