Impact of Housing Patterns on Physiological and Production Performance for Egyptian Buffaloes and Cows in Nile Valley

Abstract

The present study was connected in Nile Valley (Beni Suef Governorate). Data was collected from the seven districts within Governorate (from December 2013 to June 2015). The main objects were to study the impact of different patterns of roof house on physiological and productive performance for buffaloes and cows under environmental condition in Nile Valley. Also, to study the relationship between bedding under animal and gases emissions of house to mat modifications to reduced impact of climatic change. Addition to the best system of animal housing under this environmental conditions. Meteorological data including air temperature (AT °C), relative humidity (RH %), during the experimental period to calculate temperature humidity index (THI). The productive performance: recording total milk yield (TMY/kg) and lactation period (LP/ day). Physiological performance: recording respiration rate (RR r/min). Recording emission gas (N2O/L) from bedded under animal and (CO2/L) was estimated from N2O. The semi open System was the lower value of heat dissipation (HD/°C) under environmental in Nile valley. The best roof was mat and maize stoke respectively for two species. Cottonwood good bedded compared with rice straw to reduce emission gas. Dirt land only was good without any bedded from values of RR r/min, heat dissipation from house (HDH/°C) and gas emissions (GE/L) for two species. Values of total milk yield were high for two species under mat and maize stoke roof, and the higher value was for buffalo compared with cow. The data was recorded highly significant effect (P ≤ 0.001) for the interactions between type of roof and type of bedded on all items under this study., and the best system of animal house under the environmental conditions in Nile valley was semi open system , the roof from meat and the dirty land without bedded .
