Effects of feeding moderate-energy high-forage diets with reduced DCAD for twenty-one or forty-two days prepartum on mineral homeostasis and postpartum performance
… negative dietary cation-anion difference (DCAD) feeding in the prepartum diet would allow producers to utilize a one group dry cow pen; reducing social stress on cows while providing protection against hypocalcemia. High-fiber prepartum diets including wheat straw are inherently low in …

The effects of feeding a negative dietary cation-anion difference diet at two dietary calcium inclusion rates to close up dry cows on the subsequent lactation uterine health and fertility
… a negative dietary cation-anion difference (DCAD) diet in the prepartum phase been associated with increased biological active blood Ca levels (ionized Calcium; iCa) in the first days postpartum, linked with decrease incidences of hypocalcemia (HC) and subclinical hypocalcemia (SCH), as well …

Effects of dietary cation-anion difference (DCAD) and Na:K on dairy cows in early lactation, and the interaction of particle size reduction via mastication and rumination with digestion and passage in cattle
… the effects of dietary cation-anion difference (DCAD) and Na:K on lactating dairy cows. Replication of treatments within a 6 x 6 Latin square minimized the potential effects of outliers and allowed a surface covering a 3 × 3 matrix of DCAD and Na:K combinations to be examined. Ranges in DCAD and …

Dietary calcium and cation-anion difference influences calcium status and bone remodeling in exercising and sedentary Arabian horses
… and by dietary Ca and cationanion difference (DCAD). In experiment one, 12 Arabian horses were conditioned for 12 wk on a high speed equine treadmill. Diets were designated LH, which contained low Ca (.35%)-high Cl (.6%), LL, low Ca-low Cl (no added Cl), HH, high Ca (.7%)- high Cl, and HL, high …

Effects of Dietary Cation -Anion Difference on Performance, Acid-Base Status, and Nitrogen and Macromineral Metabolism of Lactating Dairy Cows
… used immediately after calving to compare two DCAD4 (22 and 47 meq/100 g of DM) in a completely randomized design. An additional 2.3 kg of alfalfa hay was fed during the first 5 days postpartum, and then milk, blood, and urine samples were collected weekly for 6 weeks. Repeated-measures, with …

Evaluating the inclusion of alfalfa hay in diets fed to pregnant and non-lactating Holstein cows during the prepartum period
… All diets had a dietary cation-anion difference (DCAD) below -190 mEq/kg/DM. Grass hay contained 7.5% CP, 74.9% NDF, 0.36% Ca, 0.02% Na, 1.88% K, 0.38% Cl, and 0.15% S. Alfalfa hay contained 19.6% CP, 45.6% NDF, 1.52% Ca, 0.16% Na, 2.5% K, 0.77% Cl, and 0.32% S. Cows consuming grass hay tended to …

Use of polyhalite mineral as an acidogenic product in the diets of close-up non-lactating dairy cows
Polyhalite is a natural mineral that could be fed as an acidogenic product to induce a metabolic acidosis and prevent clinical hypocalcemia in dairy cows after calving. The overall objective of this study was to determine if the use of polyhalite mineral in the diets of pre-partum non-lactating …

Sir John Finch’s (1626–1682) and Dr John Covel’s (1638–1722) Sensory Experiences in the Ottoman Empire, 1660-1690
This dissertation examines the sensory dimensions of Anglo-Ottoman encounters in the seventeenth century through a micro-history of Sir John Finch (1626–1682) and Dr John Covel (1638–1722), two English travellers whose experiences in the Ottoman Empire were shaped by cultivated perception and …
