The IgE levels and food-allergen-specific IgE- and IgG-antibodies (Ab) to ovalbumin (OA), ovomucoid (OVO) and beta-lactoglobulin (BLG) were determined up to 18 months of age in 163 infants born to women who were atopic. A high (HIGH group) or a low (REDUCED group) intake of hen's egg and cow's milk ...

Does the system work? After having been on a controlled heifer replacement program for 3 to 5 years, the entire herd will develop a short calving season resulting in more weaned calf weight per cow exposed to breeding. Wiltbank has reported on the advantage of feeding heifers for a selected ...

One hundred and fifty-eight healthy mature newborns were divided into 3 groups according to their risk of allergy: Group A, no risk (n = 62), group B, low risk (n = 30) and Group C, high risk (n = 66). Saliva was collected at birth and after 3 and 6 ...

The hind claws of 10 heifers, 10 second-calf cows, and 10 mature cows in the University of Saskatchewan's dairy herd were examined on four consecutive occasions, four and two months before calving, at calving, and two months after calving. A high prevalence of haemorrhages was observed in the sole of ...

Postmortem aging of carcasses obtained from Angus-Hereford (n = 8) and 5/8 Brahman crossbred (n = 8) heifers was investigated to determine the cause of variation in meat tenderness. Raw longissimus muscle (LM) myofibril fragmentation index was lower and cooked LM Warner-Bratzler shear force was greater for the 5/8 Brahman ...

Type information collected by the Holstein Association of Canada was combined with calving ease data from the Quebec Dairy Herd Analysis Service. Type traits considered were overall score, general appearance, dairy character, capacity, rump, rump thurl width, rump pin setting, and set of rear legs. Calving ease was considered as ...

Propolis has been used since ancient times in folk medicine for its alleged beneficial effects. It is a potent sensitizer and is well recognized as a cause of occupational allergic eczematous contact dermatitis in apiarists. Recently, there has been an increase in allergic eczematous contact dermatitis because of nonoccupational exposure ...

A cohort of 1749 newborns from the municipality of Odense born during 1985 at the University Hospital were followed prospectively for the development of IgE-mediated and non-IgE-mediated cow milk allergy (CMA) during their first year.

Secretory immunoglobulin A (SIgA) anti-casein and SIgA anti-beta-lactoglobulin (BLG) were determined in the saliva of 158 healthy mature infants at birth and in breast milk samples using a direct Elisa technique. IgG anti-casein and anti-BLG were measured in serum samples from mothers and newborns (cord blood). A high risk of ...

A 3 1/2-month-old male infant presented with hematemesis due to erosive gastritis following whole-cow's-milk feeding. The presence of eosinophilic gastritis, the disappearance of symptoms after withdrawal of whole-cow's-milk feeding, and the association with facial eczema suggest that gastritis was induced by cow's milk. Cow's-milk intolerance should be considered in the ...

A murine model for in vivo and in vitro studies of contact sensitization to methyl alkanesulphonate derivatives has been developed. Contact sensitivity was quantified in vivo by measuring the ear thickness increase, and the influence of the alkyl chain length (hexyl, dodecyl, hexadecyl) was investigated. Long chain methyl alkanesulphonates (dodecyl ...

Serum levels of IgE, IgE antibodies to egg white (EW) and cow's milk (CM), IgG, and IgA antibodies to ovalbumin (OA) and beta-lactoglobulin (BLG) were measured in a group of 115 infants with a family history of atopy/allergy at birth and at 3, 6, 9, 12, and 18 months of ...

Streptococcus agalactiae was identified as the cause of mastitis in a 240-cow dairy herd. Forty-five per cent of the herd had cell counts over 500,000/ml, and 28 per cent had cell counts over 1,000,000/ml. Dry cow therapy was used regularly but teat dipping had not been used for three years. ...

Beta-lactoglobulin (BLG) is probably the major cow milk antigen. Serum levels of anti-BLG antibodies were determined prospectively in mothers. The results were analyzed according to the existence of allergic manifestations in infants during the first months of life. Mothers of babies who developed allergy had statistically lower IgG anti-BLG concentrations ...

Two feeding trials (early and late lactation) were conducted to measure ad libitum forage intake by beef cows from three breed groups of similar mature weight, but with different milk production potential. Twenty-four cow-calf units, eight from each milk production level (low, medium and high) were grouped (two/pen) based on ...

Eleven infants who were suspected clinically of having cows' milk protein sensitive enteropathy were fed with a protein hydrolysate formula for six to eight weeks, after which they had jejunal and rectal biopsies taken before and 24 hours after challenge with cows' milk protein. When challenged six infants (group 1) ...

The effects of size, management and size x management interactions on reproduction in beef cattle were determined by using 3,126 breeding and calving records from 1980 to 1985. Cows were from three synthetic lines that differed in mature size (small, medium and large). The lines differed also in the percentages ...

Body measurements (heart and paunch girths, wither height, chest depth, pelvic length and width, and body length), body weight, and calving evaluation data (calf birth weight, calf sex, calf presentation, and calving assistance needed) were collected from 1974 parities of 762 Holstein cows between 1968 and 1986. Degree of calving ...

A study of parturient calf mortality in a herd of 250 Shorthorn cattle on the Southern Tablelands of New South Wales is reported. Death rates as high as 44% from heifer groups are described. There were 30 parturient deaths of which 27 were confirmed as due to maternal dystocia. Pathological ...

The effect of feeding different infant formulas on incidence of atopic disease was assessed in a prospective double-blind randomized controlled trial among "high risk" infants with family history of atopy among first-degree relatives. The incidence of atopic eczema, wheezing, rhinitis, gastrointestinal symptoms, and colic was noted and serum IgE antibodies ...

It has been shown in an animal model that cow's milk (CM) protein hydrolysates do not elicit an antibody response to CM proteins and do not induce passive cutaneous anaphylaxis. In addition, babies fed with these formulae during the first months of life do not show antibodies to betalactoglobulin (BLG). ...

Some infants intolerant to cow's milk protein (CMP) are often also intolerant to other food proteins including soy protein (SP). The effect of CMP and SP in infants recovering from diarrhoeal disease was studied in 22 infants who were maintained on an hypo-allergenic formula for 4-6 weeks. The infants were ...

Fifteen Jersey sires, with significant impact on the breed in the United States, were assayed for activity of uridine monophosphate (UMP) synthase. Six of these bulls were the highest ranking Jersey bulls, as July 1987, with cheese yield dollars averaging $165. These 15 bulls sired over one-third of all Jersey ...

A 2-yr study was conducted to evaluate the effects of a high-energy creep feed, preweaning zeranol implants and breed type on calf and cow performance. Two hundred calves sired by Brahman and Romana Red bulls out of Angus and Angus x Brown Swiss reciprocal crossbred (F1) dams were stratified by ...

During a period of 30 months, cow's milk- or soy protein-induced colitis was diagnosed in 22 infants. All patients presented with hematochezia. Only three patients had substantial diarrhea. Colonoscopic evaluations demonstrated a characteristic mucosal appearance, manifested by aphthoid ulcerations with intervening, normal-appearing mucosa. Histologic findings included surface ulcerations and associated ...

The presence of Pityrosporum ovale was investigated in four groups of infants age 1 to 24 months, 15 with infantile seborrheic dermatitis, 15 with infantile atopic dermatitis, 15 with other infantile dermatoses, and 15 healthy infants.
