The experiment was undertaken on 20 pre-pubescent dromedary camels of 300 ± 7.0 kg average bodyweight (BW) and 1.5-2 years of age to determine change in body weight, blood biochemical and mineral profiles and morphometric parameters on rangeland grazing (GR) and supplementary stall feeding (GS) at arid northwestern part of Rajasthan over a period of 80 days. GR camels were maintained only on grazing, while GS camels were fed semi-intensively ad-lib groundnut haulms along with formulated concentrate and mineral mixture to meet maintenance requirement. Intake of young camels was determined using chromium(III) oxide as internal marker. The biomass yield of rangeland estimated was 0.54 t DM/ha. Dry matter intake (kg/day) by GR camels on rangeland grazing was lower than that by GS camels fed on supplementary feeding. The nutrient digestibility of dry matter and organic matter (P < 0.05) and crude protein was higher in GS camels than that in GR camels. Likewise, intake of digestible crude protein (P < 0.05) and metabolizable energy were higher in stall-fed young camels. Pre-pubescent camels fed on grazing had significantly (P < 0.01) low glucose and higher urea concentration compared to stall-fed camels. Final body weight of camels differed significantly (P < 0.05) between groups. The camels fed on supplementary stall feeding had significantly (P < 0.01) higher total gain (kg) and average daily gain (ADG) compared to camels on grazing. Among morphometric parameters, body length and body height showed more significant increase in GS compared to GR camels. Intake of digestible crude protein (DCP) by GR group was 43% low compared to the requirement for growing camel of 300 kg body weight. Despite this, GR camels were able to maintain body weight due to better recycling of urea which was significantly higher in comparison to GS camels. The findings of significantly (P < 0.01) low serum glucose and higher urea concentration and lower body weight gain of GR camels suggest the need of locally available protein and energy supplement in addition to grazing for better growth performance.

Biological activity of water can be apparently judged by the colonization of bacteria (microbes). In order to find out the extent of pollution and the relationship between inorganic matters and microbiota, a quantitative and qualitative analysis of bacteria in various types of sewage waters, namely sewage water by the residential colonies (group I), industrial waste water (group II), sewage treatment hub (group III), unorganized collected waste water (group IV) and old residential waste collection center (group V), of Bikaner city (Rajasthan, India) was carried out from February, 2010 to May, 2010. Water samples were taken from surface only owing to low depth and investigated for various abiotic factors (viz. transparency, pH, carbonate, bicarbonate, total alkalinity, total hardness, salinity, chloride, calcium, magnesium, sulphate, nitrate, silica, and inorganic phosphorous) and biotic factors (viz. number and diversity of bacteria). The domestic sewage water causes major water borne diseases basing upon Total Bacterial Count (TBC) and coliform Count (CC). The coliform count in the present study ranged from 2.5 to 5.12 MPN/mL. Comparision of microbial population in sewage water from all different Groups was done and the higher values of TBC and CC were recorded only in Sewage treatement hub (Group III)

On April 7, 2020, at 10h00 a living nest of White-eyed Buzzard was found in Sardarshar, Churu, Rajasthan. On April 27, 2020, at 14:00 successful hatching of all four nestlings was reported. After 20 days we examined the nest again and found only 3 nestlings in the nest.

Rhodococcus equi has been isolated from variety of land and water animals. The organism is present in soil in all continents except Antarctica. It thrives in freshwater and marine habitats, and can live in the intestine of bloodsucking arthropods. The incidence of R. equi infection has subsequently increased markedly, coincident with the era of HIV infection, advances in organ transplantation and cancer treatment.
