Adsorption of dye methylene blue from aqueous solution on the surface of sheep wool and cotton fibers was accomplished under the optimize conditions of temperature, concentration, pH, stay time duration and quantity of adsorbent. Spectrometric technique was used for the measurements of concentration of dye before and after adsorption. The percentage removal and distribution constant (KD) values...

Ocular microangiopathic syndrome is found frequently in patients with AIDS or severe HIV infection. Symptoms of this microvascular syndrome can include cotton-wool spots, hemorrhages, and Roth's spots. The clinical and functional significance of HIV-related ocular microangiopathic syndrome has not been clarified as yet. The objective of this study was to evaluate a possible association between ...

Substantial rhythms in clean wool, wax and suint production have been observed for dry, spring-shorn Merino ewes maintained od a uniform plane of nutrition in exposed pens. Changes can be related directly to mean daily temperatures. Reversed rhythms were recorded for dry, spring-shorn, grazing sheep where both nutrition and climate were changing. Thus climate corrections would enhance the nutri...

Production data from 681 yearling ewes were evaluated for the effect of ewe breed and management system on fertility, prolificacy, lamb birth weight, lamb survival, lamb weaning weight, ewe fleece weight, and total lamb weight weaned per ewe exposed. Two hundred seven straightbred Targhee (T) and 474 1/4 Finn-1/4 Dorset-1/2 Targhee (FDT) crossbred ewes managed in a range or farm flock system we...

Current status of rabbit production worldwide The rabbit is now recognized as one of the world’s major livestock species, with an estimated global yield of one million tonnedyear of rabbit carcass (Lebas et al. 1986). Europe remains the centre of world meat-rabbit production with the USSR, France, Italy and Spain supplying approximately two-thirds of this estimated world production. In the UK t...

We tested whether the abundance of C(4) vegetation in grasslands of the Mongolian plateau is influenced by grazing conditions. The analysis exploited the politically originated contrast that exists between Mongolia (low stocking rate, transhumant system) and the district of Inner Mongolia, China (high stocking rate, sedentary system). We estimated the proportion of C(4) carbon (P(C4)) in grazed...

Wool fiber diameter (WFD) is the most important economic trait of wool. However, the genes specifically controlling WFD remain elusive. In this study, the expression profiles of skin from two groups of Gansu Alpine merino sheep with different WFD (a super-fine wool group [FD = 18.0 ± 0.5 μm, n=3] and a fine wool group [FD=23.0 ± 0.5 μm, n=3]) were analyzed using next-generation sequencing-based...

The group of man-made mineral or vitreous fibres (MMMFs or MMVFs) includes glass wool, rock wool, slag wool, glass filaments and microfibres, and refractory ceramic fibres (RCFs). Experimental observations have provided evidence that some types of MMVF are bioactive under certain conditions. The critical role of size parameters has been demonstrated in cellular and animal experiments, when inta...

Thyroidectomy surgery performed late in gestation results in perturbations in wool follicle development in foetal sheep, showing the importance of thyroid hormones for wool follicle development. The aim of this study was to determine the influence of transient manipulation of thyroid hormone status at a time corresponding with foetal primary wool follicle initiation. Pregnant Merino ewes (n = 1...

effects of lamb and parents coefficient of inbreeding (ci) on wool weight were studied using 10,868 wool records belonging to 3,244 iran black lambs (1,633 males and 1,611 females) representing 96 rams and 995 ewes collected during 1983-2006 from animal breeding station of abbas abad. year and month of shearing, ci of lamb and dam, sex and birth type had significant affect on wool weight among ...
