Abstract

Three management tools consistently increase milk yield in lactating dairy cows during established lactation: administrating exogenous bovine somatotropin, increased milking frequency, and increased photoperiod. Short day length during the dry period also increases milk yield postpartum. Season of year affects both yield and composition of milk. Seasonal variables known to impact milk and composition yield are photoperiod and thermal environmental variables such as temperature, wind speed, solar infrared load, and humidity. Milk composition can also be markedly altered by nutritional management. This permits the opportunity to improve the nutritional value of milk by altering milk composition through dietary management.
