The objective of present study was to derive the economic values for number of inseminations to conception, calving interval, milk yield and stillbirth, using economic data of 10 Iranian Holstein herds. The economic values were derived by using the profit function methods and differentiating a profit equation with respect to the traits of interest. The cow fertility costs herd amortization or r...

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 ...

The aim of this present study is to describe changes occurring during the milking of cows in various periods following the introduction of an AMS (automatic milking system). The following cow milking parameters were analysed: milkings per cow per day, milking yield, milking speed and milking duration. An increase in milk yield in AMS barns has been found to be possible, but it is affected by a ...

The effects of dietary inclusion of freeze-dried goat and cow milk on the utilization of zinc and selenium, and on the metabolic fate of zinc, were studied in transected (control) and resected rats (resection of 50% of the distal small intestine). Intestinal resection reduced the apparent digestibility coefficient and zinc retention in the cow milk diet, whereas these biological indices were si...

Three lactating Holstein cows (634 to 698 kg) were dosed, respectively, with 65.6 mg (44.5 microCi/mg), 131.2 mg (20.1 microCi/mg), or 8.4 mg (141.3 microCi/mg) of [14C]nitrofurazone by intramammary, intrauterine, or topical ocular administration. Intramammary and intrauterine treatments were single doses; ocular treatment was daily for 4 consecutive d (2.1 mg/d). Cows were slaughtered after 72...

antigenicity of proteins found in cow's milk is age dependent. this is primarily due to infants possessing a more permeable intestinal wall than that in adults. thus infants may acquire cow's milk allergy during their first year of life. while milk antigen specific ige may cause allergy in susceptible subjects, there is some evidence indicating that milk antigen specific igg may play some role ...

Soy milk (SM) is widely consumed worldwide as a substitute for cow milk. It is a source of vitamins, carbohydrates and sugars, but its capacity to preserve cell viability has not been evaluated. The purpose of the present study was to investigate the efficacy of SM to maintain the viability of human fibroblasts at short periods compared with different cow milks. Human mouth fibroblasts were cul...

Background: Cow milk allergy is one of the most common food allergies in young children causing a wide range of clinical syndromes due to immunologic responses to cow milk proteins. In this report we introduce an infant with dietary protein proctitis due to a cow’s milk referred with hematuria and bloody stool. Case Presentation: Our case was a 10- month old m...

OBJECTIVE To determine whether chicken-based formula can replace soy-based formula in infants with cow milk allergy. SUBJECTS AND METHODS Thirty-eight infants with cow's milk allergy, aged between 2-24 months of age were randomized to receive either chicken-based formula or soy-based formula for 14 days. RESULTS In the group of soy-based formula, 12 out of 18 infants had evidence of intoler...
