Kansas Agricultural Experiment Station Research Reports
Current consumer trends highlight the need for developing convenient and ready-to-eat snack foods that render health benefits when consumed. Rising popularity of protein-enriched foods and beverages have led to increasing awareness among consumers of health benefits related to a dairy-rich diet. The vast majority of people have adopted this lifestyle, spotting the protein’s importance in delivering vital nutrients for health and maintenance of the body, curbing hunger, sustaining a slow release of energy, and speeding the metabolism. Innovation is the key driver for the dairy snack market. The primary objective of this project was to develop an American-sourced predominantly dairy …
Effect Of Draining Volume On The Yield And Enrichment Ratio During Foam Fractionation Of Greek Yogurt Whey, Y. B. Ma, J. Amamcharla
Effect Of Draining Volume On The Yield And Enrichment Ratio During Foam Fractionation Of Greek Yogurt Whey, Y. B. Ma, J. Amamcharla
Kansas Agricultural Experiment Station Research Reports
Foam fractionation was evaluated as a cost-effective method to add value to Greek yogurt whey (GYW), a co-product of Greek yogurt manufacturing. Two separate batches of GYW were obtained from a Greek yogurt manufacturer. Whey proteins present in GYW can be concentrated and manufactured as food ingredients using a low-cost foam fractionation. The objective of this study was to apply foam fractionation with different draining volumes to GYW and evaluate its enrichment and yield of whey protein. A benchtop foam fractionation setup was built in-house, and three different foam draining volumes were used to identify the optimal processing parameters for …
Gestation Length And Overall Performance In The Subsequent Lactation Of Dairy Cows Conceiving To Holstein, Jersey, Or Angus Semen: An Observational Study, A. L. Scanavez, L. G. Mendonça
Gestation Length And Overall Performance In The Subsequent Lactation Of Dairy Cows Conceiving To Holstein, Jersey, Or Angus Semen: An Observational Study, A. L. Scanavez, L. G. Mendonça
Kansas Agricultural Experiment Station Research Reports
Breeding strategies adopted by commercial dairy herds have evolved in recent years by incorporating the use of several breeds, including beef sires. Results of such strategies on offspring performance have been studied but reports on the effects on dam’s overall performance after calving are still lacking. The goal of this observational study was to investigate the associations between sire breed of previous conception, gestation length, and postpartum performance of dairy cows. Records from Holstein and crossbred cows from a Kansas commercial herd were extracted. Data pertaining to cows that conceived from Holstein, Jersey, or Angus sires and initiated second lactation …
Relationship Between Body Condition Score Change During The Prepartum Period And Week Four Milk Yield Of Dairy Cows, C. A. Gamarra, A. L. Scanavez, L. G. Mendonça
Relationship Between Body Condition Score Change During The Prepartum Period And Week Four Milk Yield Of Dairy Cows, C. A. Gamarra, A. L. Scanavez, L. G. Mendonça
Kansas Agricultural Experiment Station Research Reports
The objectives of the study were to (1) evaluate the association between body condition score (BCS) change in the prepartum period and week four milk yield and (2) explore whether average week four milk yield can be used as an indicator of the percentage of cows having BCS loss before calving at the herd level. Cows that had excessive BCS loss had decreased milk yield in early lactation relative to cows that did not change BCS or had moderate BCS loss in the dry period. Nonetheless, monitoring average week four milk yield does not appear to be a reliable indicator …

Dairy cows can convert feeds unsuitable and unpalatable for humans into milk and play a key role in food security. Feed efficiency is usually calculated as the ratio between nutrients secreted in milk and nutrient intake, but this metric does not address concerns about human/livestock feed competition. This study aimed to evaluate whether cows fed a “zero land use” diet (diet that does not affect land used for production of human food), with or without rumen-protected amino acids, can maintain milk compared to a conventional lactation diet. Twelve second-lactation dairy cows were used in a 3×3 Latin square design experiment …
Physiologic Responses To Feeding Rumen-Protected Glucose To Lactating Dairy Cows, J. A. Sauls-Hiesterman, S. Banuelos, B. Atanasov, B. Bradford, J. S. Stevenson

Lactating Holstein cows were enrolled in a study beginning before first insemination. Cows were supplemented with a rumen-protected glucose (RPG) product to test the hypothesis that circulating progesterone concentrations could be increased by increasing blood glucose, which causes an increase in insulin, subsequently decreasing progesterone clearance by liver enzymes. Supplementation occurred at 0, 2.2, 4.4, or 8.8 lb per head per day to test a dose response. Treatment began 3 days before ovulation and continued until day 12 of the estrous cycle. Rumen-protected glucose did not impact serum concentration of glucose before or after feeding, but the change in insulin …
Impact Of Saccharomyces Cerevisiae Fermentation Product On Feed Intake Parameters, Lactation Performance, And Metabolism Of Transition Dairy Cattle, K. Olagaray, S. E. Sivinski, B. A. Saylor, L. K. Mamedova, J. A. Sauls, I. Yoon, B. J. Bradford

ASaccharomyces cerevisiaefermentation product (NutriTek; Diamond V, Cedar Rapids, IA) was fed from 29 ± 5 days before calving and through 42 days in milk (DIM) to evaluate the effects on feed intake parameters, milk production, and metabolism. Treatments were control (n= 30) or 18 g/d NutriTek (NT,n= 34) provided as total mixed rations. Cows were individually fed 3×/day prepartum and 2×/day postpartum. Cows were milked 2×/day with samples taken 2×/week for composition analysis. Body weight (BW) was measured at enrollment (day -29 ± 5), day 0, and day 42 relative to calving, and body …

Dominance Of Right Ovary Structures In Lactating Dairy Cows, J. S. Stevenson
Kansas Agricultural Experiment Station Research Reports
The objectives were to determine the absolute and relative ovary location of dominant and preovulatory follicles and corpora lutea (CL) present in ovaries before and during hormone synchronization and their associations with CL regression, ovulation, and pregnancy rates in lactating dairy cows. Cows were exposed to presynchronization treatments of PGF2a, GnRH, or both, 3 to 4 weeks before initiating a timed artificial insemination (AI) program (GnRH-1 – 7 days – PGF2α[1 dose or 2 doses 24 hours apart] – 56 hours after first or only dose of PGF2α– GnRH-2 – 16 hours – timed …
