fourteen primiparous holstein cows (180.0 ± 4.3 days in milk) with a mean (±sd) daily milk yield of 35.0 ± 1.3 kg and a body condition score of 3.2 ± 0.2 were allotted into two groups (n = 7), and were fed a ration consisting of (dry matter basis) 35% corn silage, 25% alfalfa hay and 40% concentrates. salt was provided free choice. the experiment was performed during the period of heat stress, ...

water is a unique natural resource among all sources available on earth. it plays an important role in economic development and the general well-being of the country. this study aimed at using the application of water quality index in evaluating the ground water quality innorth-east area of jaipur in pre and post monsoon for public usage. total eleven physico–chemical characteristics; total dis...

The Colorado River is a principal source of water for 40 million people and farmlands in seven states the western US Republic Mexico. river has been under intense pressure from effects climate change anthropogenic activities associated with population growth leading to elevated total dissolved solid (TDS) suspended (TSS) concentrations. Elevated TDS- TSS-related issues basin have direct negativ...

Robust statistical tools were applied on the water quality datasets with the aim of determining the most significance parameters and their contribution towards temporal water quality variation. Surface water samples were collected from four different sampling points during dry and wet seasons and analyzed for their physicochemical constituents. Discriminant analysis (DA) provided better results...

the karkheh dam reservoir with a capacity of more than 5 billion cubic meter is the largest dam in iran with both agricultural and drinking usages. its hydrodynamics and water quality were modeled and simulated to analyze the total maximum daily load (tmdl) of total dissolved solids (tds). the simulation was supported with measurements of temperature and tds measurements during two years. a lat...

Tujuan dari ini adalah untuk mengetahui perubahan kadar tercemar setelah dalam waktu 24 jam tertentu. Sampel yang diambil berasal berlokasi Malang terindikasi cemaran limbah pasar. Air empat titik yaitu titik1 berjarak 250 meter sebelum pintu pembuangan pasar, 2 m...

Abstract The estuaries of Banten Bay have sandy sediment, and their main activity is fisheries. In order to maintain fishery productivity, good water quality required. sediment in this location can affect conditions at the point residue content. This study aims reveal solids content Bay. A survey was conducted four estuaries, namely Karangantu, Wadas, Cengkok, Pamong. TDS were measured situ Apr...

in recent years, the groundwater resources in guilan province have played an important role in irrigating paddy fields. the goal of this study was to evaluate temporal and spatial variations of groundwater quality in a 4-year period using ordinal kriging. water samples for this study were collected from 130 wells across guilan province, in september and march from 2003 to 2006.  maps of ec and ...

The drinking, borewell and sewage water in the Sanmugasikamani Nadar (S.N) street, Naivatti Nadar (N.N) street and Thiruthangal area of Sivakasi has been studied. The various constituents monitored include the physicochemical characters like pH, total solids, total dissolved solids, total suspended solids; chemical parameters like total alkalinity acidity free CO2, dissolved oxygen, total hardn...
