Dynamics of follicular growth and progesterone concentrations in cyclic and anestrous suckling Nelore cows (Bos indicus) treated with progesterone, equine chorionic gonadotropin, or temporary calf removal
(ElsevierNova York, 2014-03-15)
The objective of this study was to investigate the effects of eCG and temporary calf removal (TCR) associated with progesterone (P4) treatment on the dynamics of follicular growth, CL size, and P4 concentrations in cyclic ...
Use of supplements and variation in the stocking rate in cow-calf systems on temperate pastures in Chile: a simulation approach
(CSIRO PUBLISHING, 2009)
A simulation model was developed to evaluate the productive and economic effect of the variation in feed practices and stocking rate of a cow-calf system in Chile. Winter supplementation at grazing, stocking rate and ...

Evaluation of mannan-oligosaccharides offered in milk replacers or calf starters and their effect on performance and rumen development of dairy calves
(REVISTA BRASILEIRA ZOOTECNIA BRAZILIAN JOURNAL ANIMAL SCIVICOSA-MG, 2012)
The objective of this study was to evaluate the route of administration of mannan-oligosaccharides in the diet of dairy calves and their effects on performance and plasma parameters indicative of rumen development. Following ...
Effects of temperament and acclimation to handling on feedlot performance of Bos taurus feeder cattle originated from a rangeland-based cow-calf system
(Amer Soc Animal Science, 2012-12-01)
Two experiments evaluated the effects of temperament and acclimation to handling on performance of Angus x Hereford feeder cattle reared in extensive rangeland systems until weaning. In Exp. 1, 200 calves (n = 97 for yr ...
Dispersion of bamboo type multi-wall carbon nanotubes in calf-thymus double stranded DNA
(2013)
We report for the first time the use of double stranded calf-thymus DNA (dsDNA) to successfully disperse
bamboo-like multi-walled carbon nanotubes (bCNT). The dispersion and the modified electrodes were
studied by different ...
Interaction of Cu-dipeptide complexes with Calf Thymus DNA and antiproliferative activity of [Cu(ala-phe)] in osteosarcoma-derived cells
(Pergamon-Elsevier ScienceOxford, 2009-08)
In this work the study of Calf Thymus DNA interaction with several Cu(l-dipeptide) complexes was reported. The binding stoichiometry (Cu(mmol)/DNAmol base) was determined and in an attempt to clarify the binding mode, EPR ...
Effect of temporary calf removal numbers in timed artificial insemination protocols on weaning weight from nelore calves
(2013-01-01)
This study was conducted to evaluate the effect on the weaning weight of Nelore calves from two factors: the number of times the calves were temporarily removed from their mothers during a timed artificial insemination ...
Isolation and molecular characterization of a new Neospora caninum isolate from cattle in Argentina
(Academic Press Inc Elsevier Science, 2015-08)
Neospora caninum is one of the most important causes of bovine abortion, but isolation of live parasites from infected tissue is difficult. The aims of the present study were to obtain new isolates of N. caninum from ...
