Cattle Update: Fall Nutritional Considerations
Cattlenetwork.com
The fall season provides an opportunity for the spring calving cow/calf producer to economically restore body condition to thin cows. During this period most spring calving cows will be the mid-gestation stage of reproduction. As always the producer needs to be aware of the nutritional requirements of the cow at various production stages and have an understanding of forage quality in order to match up nutritional needs with forage options.
Nutrient requirements for cows in mid-gestation are the lowest of any production stage. This means that low quality feedstuffs can be utilized to meet nutrient requirements of cows that do not need to improve body condition and better quality feedstuffs can economically put gain on cows that need to improve body condition before late gestation. Using crude protein (CP) and total digestible nutrients (TDN) as indicators, the mid-gestation cow requires a diet containing 7.0 % CP and 48.8%TDN according to Beef NRC (National Research Council) recommendations. Remember that pregnant heifers still have a growth requirement that must be met in addition to body maintenance requirements, so their ration needs to provide higher levels of CP and TDN; somewhere in the 54 to 55 % range for TDN and around 8 to 8.5% CP at this mid-gestation stage.
