Partial Calcium Depletion During Membrane Filtration Affects Gelation Of Reconstituted Milk Protein Concentrates, H. Eshpari, R. Jiménez-Flores, P. S. Tong, M. Corredig Dec 2015

Partial Calcium Depletion During Membrane Filtration Affects Gelation Of Reconstituted Milk Protein Concentrates, H. Eshpari, R. Jiménez-Flores, P. S. Tong, M. Corredig

Dairy Science

Milk protein concentrate powders (MPC) with improved rehydration properties are often manufactured using processing steps, such as acidification and high-pressure processing, and with addition of other ingredients, such as sodium chloride, during their production. These steps are known to increase the amount of serum caseins or modify the mineral equilibrium, hence improving solubility of the retentates. The processing functionality of the micelles may be affected. The aim of this study was to investigate the effects of partial acidification by adding glucono-δ-lactone (GDL) to skim milk during membrane filtration on the structural changes of the casein micelles by observing their chymosin-induced ...

Animal, Dairy, and Veterinary Science Faculty Publications

The present retrospective study investigates pregnancy rates, incidence of pregnancy losses and large offspring syndrome (LOS), and immune-related gene expression of sheep and goat somatic cell nuclear transfer (SCNT) pregnancies. We hypothesized that significantly higher pregnancy losses observed in sheep SCNT pregnancies compared to goats are due to the increased amounts of T-helper 1 cytokines and pro-inflammatory mediators at the maternal-fetal interface. Sheep and goat SCNT pregnancies were generated using the same procedure. Control pregnancies were established by natural breeding. Although SCNT pregnancy rates at 45 days were similar in both species, pregnancy losses between 45 and 60 days and ...

Nutrition, Dietetics, and Food Sciences Faculty Publications

Cheese can be modeled as a filled gel whereby milkfat globules are dispersed in a casein gel network. We determined the filler effects using Sephadex beads (GE Healthcare Life Sciences, Pittsburgh, PA) as a model filler particle. Ideally, such a model could be used to test novel filler particles to replace milkfat in low-fat cheese. Low-filler (6% particles), reduced-filler (16%), and full-filler (33%) cheeses were produced using either Sephadex beads of varying sizes (20 to 150 μm diameter) or milkfat. Small- and large-strain rheological tests were run on each treatment at 8, 12, and 18 wk after cheese manufacturing. Differences ...

Tri-State Dairy Youth Expo has been a long standing program that has been in existence since the early 1980’s. A donation from the Iowa State Dairy Association allowed a group to develop the Iowa Dairy Expo, now known as Tri-State Dairy Youth Expo. It began in 1984 at the Waterloo Cattle Congress as a dairy cattle judging show with commercial exhibits and informational seminars targeted mainly at dairy producers. As dairy farms changed and Iowa saw a decrease in dairy farms, the dairy sale diminished and locations changed from Waterloo to Dubuque to Decorah, and eventually to Calmar, Iowa ...


Impact Of Including Calf Gender In Models To Predict Breeding Values For Lactation Yields In Dairy Cattle, Melanie K. Hayr, Andrew S. Hess, Dorian J. Garrick Jan 2015

Impact Of Including Calf Gender In Models To Predict Breeding Values For Lactation Yields In Dairy Cattle, Melanie K. Hayr, Andrew S. Hess, Dorian J. Garrick

Animal Industry Report

Foetal calves produce sex hormones that can enter the maternal bloodstream. Male calves typically have longer gestations than female calves resulting in shorter lactations in pastoral production systems. Both of these phenomena could influence milk yields of the dam. North American and French studies have reported conflicting results as to the size of calf gender effects on milk yield. This study used a dataset from New Zealand dairy cattle to fit calf gender effects and quantify the impact of including calf gender when estimating breeding values. The regressions of lactation yield on days in milk were different for second parity ...
