Managerial and Nutritional Manipulation to Reduce Swine Odor
… technologies, and dietary manipulation to reduce urine pH and swine odor. The first section, iron bioavailability, contains three experiments which were conducted as hemoglobin depletion/repletion studies involving newly weaned iron-deprived piglets. The experiments determined the iron …

Use of polyhalite mineral as an acidogenic product in the diets of close-up non-lactating dairy cows
… as an acidogenic product. We measured the urine pH, dry matter intake, milk yield, and calcium and magnesium concentration of urine and serum in pre-partum and non-lactating dairy cows consuming diets containing a low dose of polyhalite (200 g/cow/day), a high dose of polyhalite (400 …

Evaluating the inclusion of alfalfa hay in diets fed to pregnant and non-lactating Holstein cows during the prepartum period
… were to determine the dry matter intake, urine pH, Ca concentration in blood, Ca output in urine, and incidence of hypocalcemia from pregnant, non-lactating dairy cows during the prepartum period consuming diets containing either grass hay (GH) or alfalfa hay (AH) with the inclusion of …

Effects of nutritional strategies on rumen environment and performance in dairy cows
… 2007; Enemark, 2008). The effects of SARA on urine, fecal pH, milk yield and milk composition, and starch digestibility were determined. Six Holstein cows (HOL), six rumen-cannulated Holstein cows (CAN), and six Jersey cows (JER) were used in a replicated 3 × 3 Latin square design balanced to …

Effects of fermenten during the dry and early lactation periods of dairy cows
… contains anionic salts, and was found to reduce urine pH. Cows fed Fermenten had a higher incidence of metabolic disorders. Based on these results, Fermenten is not recommended in the diets of close-up dry cows.

Offering sodium bentonite and sodium bicarbonate free-choice to lactating dairy cattle
… of sodium bentonite and sodium bicarbonate on physiological and production parameters. Eight Jerseys and seventeen Holsteins (four fistulated) were randomly assigned to two groups to equalize stage of lactation, age and production history. Two diets were fed: diet 1 without added sodium …

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
… 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 as a host of other …

Investigating the effect of yeast and mineral dietary supplements during the periparturient period on the production, physical health, and innate immune system of dairy cows
… needs of lactation production. This homeorhetic phase requires the coordination of numerous hormones and tissues to mobilize fat for energy, stabilize mineral fluctuations such as calcium, and adjust the rumen environment to the change in diet. This transition is also the cause of common early …

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
… anions induced a metabolic acidosis reducing urine pH for 21-ND and 42-ND compared to CON. Prepartum DMI was not affected by prepartum anionic supplementation. Postpartum DMI tended to be higher for anionic diets than the control diet (20.1 vs. 18.1 kg/d). Prepartum anionic supplementation …

The effect of supplementary maize silage on rumen function in dairy cows grazing high quality pasture : A thesis submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
… silage altered the diurnal pattern of rumen pH, with the pH of maize supplemented cows being significantly higher than that of pasture-fed (control) animals for several intervals of the day. Consequently, the diurnal rumen pH curve was flatter as a result. This increase in mean rumen pH with …

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
… weekly and analyzed for components. Rumen and urine samples were collected and analyzed for pH on the last 3 d of each period. The MIXED procedure of SAS was used for ANOVA. There were no response surface effects of treatment on milk production and components, or DMI (P<0.05). Acetate, …

Development of novel fertilizer manufacturing processes using human urine
… of research on how to integrate and normalize urine as a resource has been conducted, including topics such as source-separation, fertilizer effectivity, public perception, and logistics. Another important aspect is the urine treatment method and how resources are recovered. This is because …
