The in vivo effects of 1,25-(OH)2D3 were assessed using fetuses from normal and thyroparathyroidectomized (TPTX) pregnant rats. 21.5-day old decapitated fetuses from TPTX mothers exhibited lowered basal plasma calcium, elevated basal plasma phosphate and an increased percentage of total ash compared to intact littermates. In decapitated fetuses from normal mothers, neither plasma calcium nor pl...

Adsorption is an effective remediation technique for petroleum hydrocarbons because of its ease of use and high efficiency. The utilization of high-carbon content industrial by-products in such applications can present significant economic and environmental advantages. In this study, batch adsorption tests and petrographic analyses were used to investigate the adsorption of two nonpolar petrole...

Sixty gravid crossbred gilts were allotted to a 2 x 3 x 2 factorial arrangement of treatments: two Ca sources (sun-cured alfalfa meal and CaCO3), three dietary concentrations of Ca (50, 75, and 100% of NRC requirements), and two phases of gestation (55 and 105 d). The objectives were to determine the effect of Ca source, dietary Ca concentration, and gestation phase on bone characteristics (bon...

A study was conducted with gravid gilts to determine the bioavailability of Ca in sun-cured alfalfa meal (AM) and the effect of dietary Ca concentration on bone and blood characteristics during two phases of gestation. Two Ca sources (AM and CaCO3), three dietary concentrations of Ca (50, 75, and 100% of the NRC requirement), and two gestation phases (55 and 105 d) were used in a 2 x 3 x 2 fact...

wide variety of timings and techniques has been used based on the housing, production, availability of requirements etc. this current study was done for a morphologic evaluation of the cow's digit in different trimming times. a dairy herd with 2200 milking cow, free stalls barns, average daily production of 36 liters per cow was selected. forty cows were assigned to four groups based on hoof tr...

An experiment was conducted to study the eff ect of phytase enzyme (Natuphos 500) supplementation in Japanese quail (Coturnix japonica) (3 to 45 days of age) on body weight, carcass performance, percentage of tibia bone ash and tibia phosphorus. Data were analyzed as a completely randomized design arranged with fi ve levels (150, 300, 600, 1200 and 2400 FTU/Kg) of phytase enzyme as treatments 1...

an anatomic study on ovine hoof to find a proper hoof trimming method was done. fore and hindlimbs of 15, two years old ewes. were studied all legs were transferred to vet college and divided by fore and hindlimbs, left and right and lateral and medial digits. toe height to ground and to the solar surface, heel height, sole length, toe length, toe length to the sensitive tissue, sole thickness ...

The Mistaken Point and Trepassey formations (Conception and St. John’s groups, respectively) comprise a terminal Neoproterozoic, deep-marine succession of fine-grained turbidites and volcanogenic deposits that are part of the Avalonian Terrane. Debris-flow beds, slumped units, the low dispersion of turbidity-current paleoflow directions, and the absence of wave-generated structures together ind...
