This animal simulation model, named e-Cow, represents a single dairy cow at grazing. The model integrates algorithms from three previously published models: a model that predicts herbage dry matter (DM) intake by grazing dairy cows, a mammary gland model that predicts potential milk yield and a body lipid model that predicts genetically driven live weight (LW) and body condition score (BCS). Bo...

The effect of cow size on reproduction has become of in, respectively. The hip heights of the small, medium greater concern in recent years as a result of marked and large frame-size bulls used were 53, 55 and 57.5 in, increases in cow size in both purebred and commercial respectively, at 2 yr of age. The bulls were selected from herds and the extremely large effect of fertility on the within t...

Basil belongs to the Lamiaceae family, is one of the most important aromatic and medicinal plants, which it widely cultivated in many countries. The areal parts, especially leaves of sweet basil are widely used to enhance the flavor of foods such as salads, pasta, tomato products, vegetables, pizza, meat, soups, marine foods, confectioneries and other products. This study was conducted to inves...

OBJECTIVE To determine the response, in terms of fecal hemoglobin excretion and clinical symptoms, of normal 9 1/2-month-old infants to being fed cow milk. DESIGN Longitudinal (before-after) trial in which each infant was fed formula for 1 month (baseline) followed by 3 months during which cow milk was fed. SETTING Healthy infants living in Iowa City, Iowa, a town with a population of about...

pregnancy rate is one of the most important factors determining profit or loss. Considerable emphasis and focus is placed on the nutritional and reproductive management of the cow herd; but, unfortunately, in most operations little emphasis is placed on the bull. However, each bull is expected to impregnate from 15 40 females during the breeding season in a typical cow-calf operation and, thus,...

In this investigation, some epidemiological studies were run on subclinical mastitis for totally 350 dairy cows of different breeds, ages and distributed in different villages in Assiut governorate, Assiut, Egypt, along a whole year (during the period from June 2006 till July 2007) through field screening surveys by using of the California mastitis test (CMT) for each quarter milk sample follow...

BACKGROUND Cow hair and dander are important inducers of occupational allergies in cattle-exposed farmers. To estimate allergen exposure in farming environments, a sensitive enzyme immunoassay was developed to measure cow hair allergens. METHODS A sandwich ELISA was developed using polyclonal rabbitantibodies against a mixture of hair extracts from different cattle breeds. To assess the speci...

Study was carried out to understand and compare architecture of the proteins of erythrocyte cell surface of some mammals viz., Homo sapiens (human), Sus scorfa domestica (pig) and Bos taurus domestica (cow). In this study, we investigated the action of proteinases viz., trypsin and chymotrypsin and neuraminidase on the erythrocyte surface proteins and erythrocyte agglutination tendency with a l...

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. ...
