Abstract Background Lameness is defined as altered or abnormal gait due to dysfunction of the locomotor system, and a health issue feedlot cattle, having major economic, labour, welfare implications. Digital dermatitis (DD—a lesion plantar surface foot) foot rot (FR—affects interdigital cleft) are common infectious causes lameness in feedlots. These hoof lesions can occur alone combination (DD + FR) same hoof. A total 208 swabs were collected from three commercial feedlots located southern...

The immunoglobulin G (IgG) uptake and enterocyte nucleus position in the villous were studied newborn goat kids fed or lyophilized bovine colostrum. Two groups of 15 kids, each received 5% body weight colostrum (GC) (LBC) containing 55 mg/mL at 0, 7 14 h life. Three animals sampled just after birth, receiving no intake, to be used as control. Samples duodenum, medium jejunum ileum collected 18, 36 96 IgG vacuoles not observed duodenum throughout experiment regardless all experimental time...

Samples duodenum, jejunum, ileum, liver were collected at 18, 36 96 life quantify total protein, DNA RNA contents. In jejunum highest levels protein higher protein/ ratio observed 18...

The present study investigated enterocyte ultrastructure using transmission electron microscopy during IgG uptake in postnatal goat kids fed with colostrum. Six animals received 5% of body weight colostrum at 0, 7 and 14 h life were randomly slaughtered 18, 36 96 (n = 2) for the collection duodenum, jejunum ileum. Two other sampled immediately after birth without ingestion constituting a 0 group. enteric tissues analyzed characteristics, immunocytochemistry labeling immunoglobulin G (IgG),...

Bovine colostrum in natura or lyophilized was evaluated as an alternative source of passive immunity for goat kids. Twenty-five female newborn kids were randomly allotted into five treatments: A (GCA) bovine (BCA) with 45–55 mg/mL IgG, (LBC) B (GCB) (BCB) 15–25 mg/mL. The animals received 5% body weight at 0, 12 and 24 h after birth, then, cow milk twice a day concentrate ad libitum until 60 days age. Blood samples collected 0 to age determine total serum protein (TP) fractions by...

Colostrum intake in newborn goat kids is essential for the acquisition of immunoglobulins (Ig) and influencing development gastrointestinal mucosa. The present study investigated small intestine structure postnatal kid fed lyophilized bovine colostrum, an alternative source antibodies to ruminants, or colostrum using scanning electron microscopy technique. At 0, 7 14 h life 15 male newborns received 5% body weight (LBC) (GC), both with 55 mg/mL IgG. Samples duodenum, medium jejunum ileum...

Growth performance was evaluated in juvenile pacu (Piaractus mesopotamicus) and dourado (Salminus brasiliensis) fed diets containing 0%, 10% 20% of lyophilized bovine colostrum for 60 days. The variables weight gain, relative feed intake, conversion ratio, specific growth rate, total protein intake efficiency ratio were as well apparent digestibility coefficients energy the diets. Inclusion did not induce differences (P > 0.05), indicating that adequate met nutritional needs juveniles. both...

Digital dermatitis (DD) is a costly hoof infection, causing lameness and pain in feedlot cattle. DD lesions can develop nonlinearly through series of clinical stages, which be classified by Dopfer’s M-stage scoring system. This widely adopted lesion system recognizes five where M1 (early lesion), M2 (acute ulcerative M4.1 (chronic proliferative with new developing lesion) are considered active but separate stages the disease. study assessed skin surface microbiota The from three commercial...
