Lamb fattening in cages or on straw litter

Egg comonents of the native fars chickens in cages and on deep-litter

Gaseous emissions during the fattening of pigs kept either on fully slatted floors or on straw flow.

The aim of this study was to compare the environmental impact of the straw-flow system for fattening pigs with the slatted-floor system by measuring pollutant gas emissions such as ammonia (NH3), nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2), manure nitrogen (N) content and emissions of water vapour (H2O). Three successive batches of 32 pigs were fattened. For each batch, pigs wer...

Evaluation of the Nutritional Value of Ammoniated Wheat Straw by Anhydrous Ammonia in Fattening Calves Feeding

Extended Abstract Introduction and Objective: Processing of agricultural by-products for animal feed can upgrade the supply of animal feed without increasing the current production and only by improving productivity via enhancing energy efficiency and maintaining it in the food supply chain, and at the same time, diminish the concerns of waste management, food security, resource constraints, a...

Effect of Feeding Dietary Treated Wheat Straw with Urea and Whey on Fattening Lambs Performance

This study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. About 4.5 kg urea and 1.5 kg salt were dissolved in 40 L water and mixed with 30 L of whey. The solution was spread over 100 kg chopped wheat straw. Thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...

Blood parameters in fattening pigs fed whole-ear corn silage and housed in group pens or in metabolic cages.

The aim of this work was to evaluate the effects of the inclusion of whole-ear corn silage (WECS) in diets for advanced fattening heavy pigs (substitution for part of the dry corn and wheat bran) allocated or not in metabolic cages on the main blood parameters. The high-moisture shelled corn is largely used in pig feeding while WECS is less often used despite the fact that it increases the DM c...
