The objective of this study was to evaluate effects of cow breed-type (two-breed rotations of Simmental x Hereford, Angus x Hereford, and Tarentaise x Hereford) and breeding system (rotational vs terminal sires) on production efficiency to weaning. Cows were limit fed in drylot for one year to simulate weight change of range cows. Both cow breed-type and sire type significantly affected efficie...

For the rapid and accurate identification of cow reproduction and healthy behavior from mass surveillance video, in this study, 400 head of young cows and lactating cows were taken as the research object and analyzed cow behavior from the dairy activity area and milk hall ramp. The method of object recognition based on image entropy was proposed, aiming at the identification of motional cow obj...

Previously reported allergic reactions to orgotein (superoxide dismutase) injections has assigned responsibility to this molecule, which is obtained from bovine liver. We report an anaphylactic shock probably caused by impurities contained in an orgotein preparation. Prick test to PeroxinormTM (orgotein), BSA, and cow liver extract were positive but resulted negative with chymotrypsin, milk, me...

Fourier transform infrared (FTIR) spectroscopy combined with chemometrics of partial least square (PLS) and discriminant analysis (DA) has been developed for simple analysis of lard in the mixtures with body fats of lamb (LBF), cow (Cow-BF), and chicken (Ch-BF). The spectral bands correlated with lard, LBF, CowBF and Ch-BF as well as their lard blends were scanned, interpreted, and identified. ...

We studied the effects of goat and cow milk fat on the digestive utilization of this nutrient and on some of the biochemical parameters that are related to the metabolisim of lipids, using rats with a resection of 50% of the distal small intestine and control animals (transected). The fat content in all the diets was 10% but the lipid quality was varied: the standard diet was based on olive oil...

PAVLOVIĆ H., HARDI J., SLAČANAC V., HALT M., KOCEVSKI D. (2006): Inhibitory effect of goat and cow milk fermented by Bifidobacterium longum on Serratia marcescens and Campylobacter jejuni. Czech J. Food Sci., 24: 164–171. This study was performed to determine the influence of fermented goat and cow milk produced by the use of Bifidobacterium longum Bb-46 on pathogenic Serratia marcescens and Ca...

PURPOSE We characterize aqueous angiography as a real-time aqueous humor outflow imaging (AHO) modality in cow eyes with two tracers of different molecular characteristics. METHODS Cow enucleated eyes (n = 31) were obtained and perfused with balanced salt solution via a Lewicky AC maintainer through a 1-mm side-port. Fluorescein (2.5%) or indocyanine green (ICG; 0.4%) were introduced intracam...

BACKGROUND Lactose, as the primary osmotic component in milk, is the major determinant of milk volume. Glucose is the primary precursor of lactose. However, the effect of glucose on lactose synthesis in dairy cow mammary glands and the mechanism governing this process are poorly understood. RESULTS Here we showed that glucose has the ability to induce lactose synthesis in dairy cow mammary ep...

Dairy heifers were treated 0 to 90 d, 90 to 180 d, or 180 to 270 d prepartum with one of five different antibiotic products to determine the best time and with which product they should be treated prior to calving. Two hundred thirty-three heifers were included in the study. At the initial sampling, 56.5% of quarters were infected with some type of organism and 15.4% of quarters were infected w...

Soy-protein formulas are widely used for feeding babies with cow-milk allergy. When they first were marketed, these formulas were the only available cow-milk substitute and they ensured a normal life for many children who were affected by the large spectrum of clinical manifestations of cow-milk allergy. Soy-protein formulas were also given to allergy-prone infants for the prevention of atopic ...
