Abstract
Measurements were made of the roughage and water intake of young Friesian cross males and females throughout a 12-month period. Results showed that the roughage consumption fell by 10–16% between the temperature range 11°–20°C and 21°–30°C and by 20–43% between the temperature range 11°–20°C and 31°–40°C. Water intake increased from 30–44% between 11°–20°C and 21°–30°C and by 45–92% between 11°–20°C and 31°–40°C.
Zusammenfassung
Rauhfutterverzehr und Wasserkonsum junger schwarzbunter Kreuzungsrinder wurden während eines Zeitraumes von zwölf Monaten gemessen. Die Ergebnisse zeigen, dass der Rauhfutterverzehr um 10–16% zurückging wenn die Lufttemperatur von 11°–20°C auf 21°–30°C stieg, und um 20–43% beim Anstieg von 11°–20°C auf 31°–40°C. Der Wasserkonsum nahm zwischen 11°–20°C und 21°–30°C um 30–44% und zwischen 11°–20°C und 31°–40°C um 45–92% zu.
Resume
Pendant une période de douze mois, on a cherché à mesurer la quantité d'eau et de foin consommée par un jeune bétail de race Friesian en Irak. Les résultats furent les suivants: Lors d'une augmentation de température de 11°–20°C à 21°–30°C, la consommation de foin diminua de 10 à 16%, allant même jusqu'à diminuer de 20 à 43% lors de températures augmentant de 11°–20°C à 31°–40°C. La consommation d'eau, quant à elle, augmenta de 30 à 44% dans le premier cas et de 45 à 92% dans le second.
