Influence Of Neck-Rail Placement On Free-Stall Preference, Use, And Cleanliness, Cassandra B. Tucker, Daniel M. Weary, David Fraser Aug 2005

Influence Of Neck-Rail Placement On Free-Stall Preference, Use, And Cleanliness, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

Three experiments examined how the presence of a neck rail at different heights and locations influenced dairy cattle behavior and stall cleanliness. Experiment 1 compared 4 levels of neck-rail height (102, 114, and 127 cm and no neck rail; presented at 160 or 180 cm from the curb) in a preference test. Cows (n = 10) showed no consistent preference based on neck-rail height, regardless of the horizontal position of the neck rail. When cows were restricted to each treatment in turn, however, time spent standing fully (with all 4 hooves) in the stall was least in the stall with …

Effect Of Fat And Casein Particles In Milk On The Scattering Of Elliptically Polarized Light, Czarena L. Crofcheck, Jeremie Wade, Janakiraman N. Swamy, Mustafa M. Aslan, M. Pinar Mengüç May 2005

Effect Of Fat And Casein Particles In Milk On The Scattering Of Elliptically Polarized Light, Czarena L. Crofcheck, Jeremie Wade, Janakiraman N. Swamy, Mustafa M. Aslan, M. Pinar Mengüç

Biosystems and Agricultural Engineering Faculty Publications

In this article, we present an experimental approach to determine the milk fat content using scattered light intensity profiles. The elements of the scattering (Mueller) matrix have been shown to provide valuable information about variation of the optical properties of scattering particles. The scattering behavior of fat and casein in terms of the scattering matrix elements was experimentally determined for milk with varying fat levels ranging from 0.05 wt% (skim) to 3.20 wt% (whole). Three of the scattering Mueller matrix elements, specifically S11, S12/S11, and S33/S11, were found to be …

Physical Properties Of Yogurt Fortified With Various Commercial Whey Protein Concentrates, Isabelle Sodini, John Montella, Phillip S. Tong Apr 2005

Physical Properties Of Yogurt Fortified With Various Commercial Whey Protein Concentrates, Isabelle Sodini, John Montella, Phillip S. Tong

Dairy Science

The effects of whey protein concentrates on physical and rheological properties of yogurt were studied. Five commercial whey protein concentrates (340 g kg−1 protein nominal) were used to fortify milk to 45 g protein kg−1. Fermentation was performed with two different starters (ropy and non-ropy). Resulting yogurts were compared with a control yogurt enriched with skim milk powder. The water-holding capacity of the yogurt fortified with skim milk powder was 500 g kg−1 and ranged from 600 to 638 g kg−1 when fortified with whey protein concentrates. Significant rheological differences have been noticed between the …

Effects Of A Proteolytic Feed Enzyme On Intake, Digestion, Ruminal Fermentation, And Milk Production, Jong-Su Eun, K. A. Beauchemin Jan 2005

Effects Of A Proteolytic Feed Enzyme On Intake, Digestion, Ruminal Fermentation, And Milk Production, Jong-Su Eun, K. A. Beauchemin

Animal, Dairy, and Veterinary Science Faculty Publications

The effects of exogenous proteolytic enzyme (EPE) on intake, digestibility, ruminal fermentation, and lactational performance were determined using 8 lactating Holstein cows in a double 4 ×4 Latin square experiment with a 2 ×2 factorial arrangement of treatments. Diets based on barley silage and alfalfa hay as the forage sources were formulated to maintain different forage to concentrate ratios [60:40 vs. 34:66, dry matter (DM) basis]. Four dietary treatments were tested: high forage (HF) without EPE (HF−EPE), HF with EPE (HF+EPE), low forage (LF) without EPE (LF–EPE), and LF with EPE (LF+EPE). The EPE, which contained proteolytic activity but negligible …
