The influence of somatic growth and genetic selection on the whole blood oxygen equilibrium curve (OEC) was measured under standard conditions in double-muscled and dairy calves during their first 3 mo of life. Crossbreed animals were also investigated. Hemoglobin, 2,3-diphosphoglycerate (DPG), Cl, and Pi concentrations were also measured. The percentage of fetal hemoglobin (HbF) was determined...

Two experimental factors (dietary treatment with or without pelleted-concentrate supplement (PCS) and sex) were investigated in crossbreed post-weaning calves to monitor their effects on performance, hematological profile, and plasma mineral concentration. Twenty-four post-weaning calves were classified according to sexually (either male or female) and randomly distributed into two dietary trea...

Abstract Previous research has shown surplus dairy calves arrive at ‘formula-fed’ veal operations in North America sub-optimal condition; however, little is known about the condition of ‘bob’ on arrival abattoirs. The objectives this study were to assess bob an abattoir Ohio and determine risk factors for poor health outcomes. On arrival, 35 each 12 cohorts (n = 420 calves) assessed using a sta...

Ongole Grade cattle development continues to be carried out, because it has a uniform physical form and genetic composition, as well the ability adapt environmental constraints. Selection of beef can done by considering quantitative characteristics cattle, so that with best performance obtained. The aim study was analyze birth weight, weaning weight (205 days), yearling in at BPTU-HPT Sembawa f...

This study aimed to compare the ferning score based on pH of cervical mucus and its relation with gestation calf gender cows. Ten Holstein Friesian crossbreed cows which were detected in estrus about be artificially inseminated, used for this study. Sample was collected using Metricheck observations. Pregnancy diagnosis conducted two months after insemination, calves recorded at parturition. in...

Tears and skin detachments were observed in a newborn calf after umbilical revision. The presumptive diagnosis of Dermatosparaxis was based on the anamnesis typical clinical signs disease, such as high fragility total detachment fragments. Three staining techniques (HE, PAS Masson’s trichrome) performed samples from affected animal, using same region normal animal with age crossbreed, ranch use...

A series of studies were conducted to determine the effect of supplemental trace mineral source on growth performance, morbidity, and trace mineral status in growing beef cattle. The first experiment evaluated supplemental trace minerals from sulfate, organic, or hydroxy sources on growth performance and morbidity. Crossbreed beef calves were assigned to 1 of 3 treatments consisting of suppleme...

Recent advances in genomics resources and tools are facilitating quantitative trait locus mapping. We developed a crossbreed pedigree for mapping quantitative trait loci for hip dysplasia in dogs by crossing dysplastic Labrador Retrievers and normal Greyhounds. We show that one advantage to using a crossbreed pedigree is the increased marker informativeness in the backcross/F2 population relati...

ABSTRACT Cryptosporidium spp. are important enteropathogen protozoan parasites that infect humans and other animals throughout the world. Cryptosporidiosis in cattle industry leads to considerable economic losses due diarrhea, dehydration, growth retardation, weight loss, possibly death, however, data on occurrence ofCryptosporidiumspp. Colombia limited. Therefore, this study aimed investigate ...
