Even in winter the rearing of calves should be ensured by proper drinking technique while we we crave cold winter fireplace evenings and mulled wine to warm us, make low temperature newborn calves no problems. If because the potions of concentration is increased accordingly. Because the ambient temperature has a great influence on the energy consumption of the calf, the maintenance dose now increases with onset of frost. You should therefore necessarily when feeding on the drinking temperature and the concentration of potions! The thermoneutral zone is located in the calf in the first three weeks of life between 15 and 25 C. At lower ambient temperatures the conservation requirement increases with decreasing temperature according to. The maintenance dose to approximately 35% increases at-4 C! Following table shows the increase in the to vertrankenden amount of milk replacer after Martin Kaske (clinic for cattle, Foundation University of veterinary medicine Hannover) significantly. Ambient temperature ( C) per day in addition to vertrankende MAT (g) lot 20 0 15 65 10 130 5 200 0 265 5 330 10 400 15 465 20 530 practice usual concentration of exchanger of 120 g per liter of water at a lot of potions from four to five liters in sub-zero temperatures no longer sufficient to meet the energy needs of calves. The animals have to dismantle their few body’s energy reserves.
This in turn leads to a weight loss. It is difficult to achieve the increased needs of an increased amount of potions, because this quantity of the calves is often not fully absorbed. For this reason, it makes sense at least to increase the concentration of 160 g / litre. Also b egg three times to twice watering increases increased in several attempts to significantly. The levels of nutrition in the first few weeks has also impact on the future performance of the animal.
In different studies (Israel/United States / Germany) was explores the relationship between drinking plan in calf rearing and the later milk yields. Result is that the cell proliferation and organ growth determine the performance potential of the dairy cow in the first few months. The basis for high milk yield is thus placed in the first months of life (postnatal programming). The calf to the demands required in the first two months 1 kg milk replacer/day. That means a 125 g MAT/litre have potions volume of 8 litres 6 litres, 150-160 g MAT per litre must be touched (at thermoneutraler environment). Summary of United States: 50% higher supply in the watering phase brings higher milk yield. Investigation of performance difference milk Foldager and Krohn, 1994 1416 kg Foldager et al. 1998 523 kg Ballard et al. 2005 706 kg (200 days) Rincker et al. 2006 504 kg (305 days) Moallem et al. 2006 1145 kg Pollard et al. 2007 843 kg watch out in the winter, the animals to provide the milk as warm. Cool milk must be warmed themselves again veal calf stomach on body temperature. This costs energy unnecessarily. When mixing, the water from the power can be very cold. Heat the milk then higher setting back longer distances with the drinking bucket up to the calf. Provide fresh water your calves also at lower temperatures. Make sure that the water pipes don’t freeze. Keep in mind the calves of today are tomorrow’s cows and secure the future of their operation.
