OBJECTIVES To evaluate the growth, tolerance, and safety of a new ultraconcentrated liquid human milk fortifier (LHMF) designed to provide optimal nutrients for preterm infants receiving human breast milk in a safe, nonpowder formulation. METHODS Preterm infants with a body weight ≤ 1250 g fed expressed and/or donor breast milk were randomized to receive a control powder human milk fortifier ...

Data of 42 balance measurements from dry and lactating Holstein cows and blood and urine samples from 24 Japanese Black cows were collected to evaluate the potential for predicting urinary nitrogen (N) excretion from plasma urea nitrogen (PUN). Similar positive correlations were obtained between N intake and apparent N absorption in dry and lactating cows. The regression equations of N intake o...

The analytical technique described in the preceding three papers lends itself peculiarly well to the determination of total uncoagulable nitrogen, urea and ammonia in blood, milk, eggs and other liquids where we are dealing with minute amounts of these different constituents. In two earlier papers results obtained by adaptations of these methods to blood analysis were published.’ The procedures...

this experiment was conducted to evaluate the effects of processing protein meals by tannin extracted from pistachio by-product on apparent total tract digestibility, ruminal fermentation and performance of dairy cows. for tannin extraction, one kilogram of sun-dried pistachio by-products was immersed in four liters of water for 48 h. then, pistachio by-products were removed from the water and ...

To determine the effects of dry period (DP) length on milk yield, milk composition, some blood metabolites, complete blood count (CBC), body weight and score and follicular status, twenty five primiparous and multiparous Holstein cows were assigned to a completely randomized design with DP-60 (n = 13) and DP-20 (n = 12) dry period lengths. Cows in the DP-60 produced more milk, protein, SNF, ser...

The liver of the cow is a cross-road of nitrogen metabolism in dairy cows. Urea is synthesized in the liver as a results of unused degradable protein in the rumen, the absorption of excess amino acids from rumen undegradable protein, and from the catabolism of amino acids that are not utilized for productive purposes. Dietary crude protein (CP, % of DM) is the one single dietary factor most clo...
