Hisardale male lambs (n=24, 4-5 month of age) were maintained on a conventional ration for a month, to equilibrate the body mineral status. Six lambs were sacrificed after one month of feeding; the samples of organs were analyzed to ascertain mineral status. The remaining 18 lambs were divided into 3 groups of 6 each on body weight basis. Three dietary treatments containing 100 (T 1 ), 110 (T 2 ) and 120% (T 3 ) of minerals (Ca, P, S, Zn and Mn) as specified by NRC (1985) were formulated and each treatment was alloted ad libitum to a group for 120 days. Blood and wool samples were collected at monthly intervals. At the end of the experiment a balance trial of 5 days duration was conducted to study the balance of mineral elements. The effective intake of minerals was Ca, 111 and 120, P, 110 and 122; S, 112 and 129; Zn, 112 and 126 and Mn, 109 and 123 percent in T 2 and T 3 , respectively, in comparison to T 1 (100). The additional mineral supplementation had no significant effect on dry matter intake. The average daily weight gain was higher (p<0.01) in T 2 and T 3 than the control (T 1 ). The lambs under treatments T 2 (8.72) and T 3 (8.47 kg) consumed apparently lesser amount of dry matter per unit gain as compared to T 1 (10.81 kg). Significantly higher (p<0.05) dry matter and crude protein digestibility (%) were observed in T 2 and T 3 than in T 1 . The mean balances for different elements were
The quality of roadside soil along the NH3 highway of high traffic density at Morena-M.P. was studied during 2010-11 at 12 different locations. The roadside soil was found to be highly contaminated. This is evident from the modification of the soil pH, Electrical conductance, Water holding capacity and other Physico-chemical properties when compared to natural soil. The presence of heavy metals like Zn, Cu, Mn, Fe in the roadside soil was also considerable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
