In terms of nutrient requirements, the stage of gestation and lactation will impact the feeding
program. Four key factors that change as the cow moves through the six phases
of the gestation lactation cycle. These four factors are discussed below.
Factor 1. Milk production curve.
Milk production drives nutrient needs for dairy cows. Peak milk sets the lactation curve for
cows. Generally, Peak milk should occur 40 to 60 days after calving. First lactation cows should reach peak milk levels 75 percent or greater than that of the peak milk of older cows in the herd.
Factor 2. Milk fat and protein curve. Milk fat and protein levels will vary by breed. If milk
fat test is below milk protein test by 0.2 points, rumen acidosis could be occurring. If milk
protein test is below breed average. or if it shifts during various phases. consider the following reasons for low milk protein production:
• Low levels of fermentable carbohydrate lowers microbial protein synthesis and amino acids for milk protein synthesis;
• Low levels of dry matter intake reduce the supply of nutrients available for the rumen microbes and cow;
• Protein shortage and/or imbalance of amino acids;
• Use of fats and oils as energy sources - fat is not a source of rumen fermentable energy.
Factor 3. Dry matter intake curve. Increasing the cow's dry matter intake after calving can
avoid metabolic disorders. Minimize weight loss. and improve reproductive performance.
Factor 4. Bodyweight loss and gain curve. Monitoring weight changes in dairy cows provide valuable information on the energy status of cows. High-producing cows will lose weight to
provide the high energy levels needed in early lactation. Body condition scoring is a field
method to monitor weight changes. The following guidelines can be used to access
weight status:
• One body condition score (using the 1 to 5 system) is equal to 120 lbs. (54.4 kg) of body
weight;
• Cows should not lose more than 1 to 1.5 body condition score points (120 to 200 lbs. [54.6 to
90.9 kg] of weight);
• The maximum weight loss is 2 lbs. (.90 kg) per day to avoid negative effects on reproduction
and metabolic disorders;
• Cows should be at the optimum body condition score prior to drying off (3.25 to 3.75). If dry cows are too thin. limit weight gain to one-half body condition score - for example. shifting dry cows from 2.75 to 3.25. which is 60 lbs. (27.3 kg) in 60 dry days, or one pound (.45 kg) per day.
