Effects Of Supplementing Methionine And Lysine In A Lactation Diet Containing High Concentrations Of Corn By-Products (2011), C.R. Mullins, D. Weber, E. Block, John F. Smith
Kansas Agricultural Experiment Station Research Reports
Ninety-six lactating Holstein cows were used to determine the effects of using commercial supplements to supply additional lysine and methionine in diets containing large proportions of corn by-products. Cows were assigned to 1 of 8 pens. Pens were offered rations formulated to differ in metabolizable lysine and methionine supply. The study was divided into 2 periods. During period 1, cows received similar diets, but the treatment diet supplied supplemental lysine and methionine. During period 2, the treatment diet was modified to reduce dietary crude protein. Feed intake and production were monitored daily, and milk components were analyzed 3 days per …

The objective of this research was to increase the proportion of cows with at least 1 functional corpus luteum (CL) and elevated progesterone at the onset of the timed artificial insemination (TAI) program. Postpartum Holstein cows in 1 herd were stratified by lactation number at calving (September 2009 through August 2010) and assigned randomly to 1 of 2 treatments: (1) Presynch-10 (n = 105): two 25-mg injections of prostaglandin F2α(PG) 14 days apart (Presynch); and (2) PG-3-G (n = 105): one 25-mg injection of PG 3 days before 100 μg gonadotropin- releasing hormone (GnRH; Pre-GnRH), with the PG injection administered …
Influence Of Dairy Housing On Freshwater Usage On Commercial Dairies In Western Kansas (2011), J.P. Potts, Michael J. Brouk
Influence Of Dairy Housing On Freshwater Usage On Commercial Dairies In Western Kansas (2011), J.P. Potts, Michael J. Brouk
Kansas Agricultural Experiment Station Research Reports
Fresh water pumping records were obtained from 24 western Kansas dairy farms for a 10-year period from 2000 through 2009. Farms were divided by facility type: dry lot (DL), free stall (FS), or a combination (DL+FS). Of the facility types studied, DL averaged smaller (P<0.05) demand for water at 52.6 gal/cow per day compared with FS at 61.3 gal/cow. Both DL and FS facilities had less water demand than the combination facilities of DL+FS at 71.1 gal/cow of water daily. In all cases, average freshwater pumping was less than the daily amount of 134.7 gal/cow commonly used in dairy facility design. The difference may result from water conservation efforts of the dairies and the efficiency gained from operating larger milking parlors.; Dairy Day, 2011, Kansas State University, Manhattan, KS, 2011; Dairy Research, 2011 is known as Dairy Day, 2011

Thirty-two Holstein transition cows were used to determine the effects of monensin (Rumensin, Elanco Animal Health, Greenfield, IN; 400 mg/cow daily) on metabolism and feeding behavior. Cows were assigned randomly, based on calving date, to control or monensin treatments (n = 16 per treatment) 21 days before their expected calving date, and cows remained on treatments through 21 days in milk. Feeding behavior and water intake data were collected daily. Blood samples were collected at 8 different time points during the experimental period. Monensin decreased mean and peak plasma ketone concentrations, and also decreased time between meals before and after …
Effects Of Dietary Amylase And Sucrose On Productivity Of Cows Fed Low-Starch Diets (2011), C.F. Vargas, Barry J. Bradford

Exogenous amylase, sucrose, or a combination was used in diets with reduced starch content. The trial was performed in 48 lactating Holstein cows, and milk yield, milk composition, and dry matter intake were measured. Treatments did not affect production traits, but with slightly decreased feed intake and slightly greater milk production in amylase-fed cows, the calculated value of amylase in this study was $0.37/cow per day.; Dairy Day, 2011, Kansas State University, Manhattan, KS, 2011; Dairy Research, 2011 is known as Dairy Day, 2011

Twenty-five Holstein cows were fed 5 different diets to evaluate amounts of metabolizable methionine provided to dairy cows from a mechanically extracted soybean meal (meSBM) with methionine added during manufacture. The control diet was designed to be deficient in metabolizable methionine supply. Two amounts of methionine were added from either a commercially available ruminally protected product (RPMet) or from a meSBM with methionine added during manufacture (meSBM-Met). Average milk yield was 98.8 lb/day, average milk fat was 2.81%, and milk urea nitrogen (MUN) averaged 8.6 mg/dL. Milk protein yield was not responsive to metabolizable methionine supply, suggesting that milk protein …

Inflammation has been proposed as a contributor to metabolic disorders in transition dairy cows. The purpose of this experiment was to determine whether a non-steroidal anti-inflammatory drug, sodium salicylate (SS), benefits transition cows. At calving, 78 cows (primiparous, n = 39; second lactation, n = 28; ≥3 lactations, n = 11) were assigned alternately to either a control (CON) or SS treatment for 7 days and remained on study until 21 days postpartum. Treatment was administered via individual water bowls at a concentration of 2.5 g/L, delivering a mean of 183 ± 8.5 g/day SS during the 7 days of …

Our objectives were to determine: (1) the effectiveness of an injection of PGF2αto regress the corpus luteum before initiating an timed artificial insemination (TAI) program, (2) ovulation response to gonadotropin-releasing hormone (GnRH), and (3) pregnancy outcomes in dairy heifers inseminated with conventional and gender-biased semen. Heifers (n = 545) from 3 locations (Florida, Kansas, and Mississippi) were assigned randomly to 1 of 2 treatments: (1) 25-mg prostaglandin F2α(PGF2α) injection and controlled internal drug release (CIDR) insert on day −7 followed by 100 μg of GnRH administered on day −5, and a 25-mg PGF2α injection at CIDR insert removal (7D) on …

Enhancing Cysteine Content In Yogurt (2011), Soumya Bala, Karen A. Schmidt
Kansas Agricultural Experiment Station Research Reports
Cysteine is considered a conditional amino acid for certain subpopulations. For example, in elderly people, cysteine has been associated with diverse functional properties as a general antioxidant as well as a specific role linked to cataract reduction or prevention. Yogurt is an excellent source of protein, the sulfur-containing amino acids methionine and cysteine in particular. Heat, however, can denature these amino acids and affect their bioavailability. A yogurt mix supplemented with whey proteins (an abundant source of cystiene) coupled with minimal pasteurization of yogurt mixes may increase the availability of cysteine in the final product. In this study, yogurt mixes …
