Evaluation of an inexpensive needle test for the diagnosis of phosphorus deficiency and management of phosphorus supplementation for cattle: A multiple case study Anais da ABC (AABC)
MALAFAIA,PEDRO; GARCIA,FELIPE Z.; LOPES,SAMARA P.; SOUZA,VINÍCIUS C.; CANELLA FILHO,CAMILLO F.C.; COSTA,DIOGO F.A.; VEIGA,CRISTIANO C.P..
ABSTRACT The needle test (NT) is a point-of-care test developed in Brazil to evaluate the Phosphorus (P) status in cattle. Based on bone resistance, the NT is a very inexpensive method which allows the diagnosis of any degree of P deficiency in a fast and simple way in vivo and directly on farm. The NT measures three levels of resistance in the transverse process (TP) of the lumbar vertebrae: a) TP that are impenetrable and result in warping of the needle (P healthy animals); b) TP offering some resistance to the penetration (animals with subclinical P deficiency); and c) TP which has minimal resistance to penetration (clinical P deficiency). This manuscript presents results from a series of case studies to evaluate the hypothesis that the NT could be used...

Mineral deficiencies in beef cattle from southern Brazil Braz. J. Vet. Res. Anim. Sci.
Valle,Stella de Faria; González,Félix Diaz; Rocha,Dimas; Scalzilli,Haydée Beatriz; Campo,Rómulo; Larosa,Verônica Lima.
Minerals play an important role in the cattle metabolism with great impact in productive and reproductive performance of animals raised on extensive grasslands. At present, there is a lack of information concerning mineral deficiency throughout the analysis of biological fluids in Rio Grande do Sul State (southern Brazil). The Central Valley region of this State is characterized by extensive production on natural pastures with poor mineral supplementation. The low levels of minerals found by previous studies on pastures in this area motivated this research. The aim of the present work was to detect possible mineral deficiencies in beef cows by determining concentrations of minerals in biological fluids and in pasture. There were determined concentrations...

Peripheral neuropathy in a copper-deficient goat Ciência Rural
Almeida,Valdir Morais de; Chaves,Hisadora Advincula da Silva; Silva Filho,Givaldo Bom da; Ribeiro,Danielle Pimentel; Braga,Thaiza Campelo; Mendonça,Fábio de Souza.
ABSTRACT: This report aimed to describe a case of peripheral neuropathy in a copper-deficient goat, and highlights the clinical, and pathological features of the disease. The goat had low body score, hyporexia, alopecia, achromotrichia, left hindlimb protraction, paralysis with dragging of digit and difficulty to stand up and microcytic normochromic anemia. Copper concentration in serum was markedly lower (2.0µmol L-1) whereas the iron serum content was significantly increased (51.0µmol L-1). The main gross alteration was the reduction of the quadriceps vastus laterallis muscle volume. Histologically, there was atrophy of the quadriceps vastus laterallis muscle and presence of satellite cells, infiltration of lymphocytes, macrophages and replacement of the...
