The selenium requirement of the puppy.
Current selenium (Se) recommendations for the puppy are based on extrapolation from other species (0.11 mg Se/kg diet). The purpose of this study was to experimentally determine the Se requirement in puppies. Thirty beagle puppies (average = 8.8 weeks old) were utilized in a randomized complete block design with age, litter and gender used as blocking criteria. Puppies were fed a low Se (0.04 mg Se/kg diet) torula yeast-based diet for 14 days (pre-test period) after which this same diet was supplemented with five levels of Na2SeO3 for 21 days (experimental period) to construct a response curve (0, 0.13, 0.26, 0.39 or 0.52 mg Se/kg diet). Response variables included Se concentrations and Se-dependent glutathione peroxidase activities (GSHpx) in serum as well as serum total triiodothyronine (TT3), serum total thyroxine (TT4) and serum free T4 (FT4). No significant changes in food intake and body weight gain occurred, and no clinical signs of Se deficiency were observed. A breakpoint for serum GSHpx could not be determined in our study due to analytical difficulties. A broken-line, two-slope response in serum Se occurred with a breakpoint at 0.17 mg Se/kg diet. When Se from the basal diet was added to this estimate, the breakpoint for serum Se equated to 0.21 mg Se/kg diet. TT3 increased linearly with increasing Se intake, whereas TT4 was unchanged. However, the ratio of TT4 : TT3 decreased linearly in response to supplemental Se. In summary, although we estimated the selenium requirement for the puppy based on serum Se, our 0.21 mg Se/kg diet estimate is higher than that seen for adult dogs, kittens, rats or poultry (0.13, 0.15, 0.15 and 0.15 mg Se/kg diet respectively). This difference may be due to the fact that GSHpx was used as the biomarker of Se status.

Wedekind KJ, Yu S, Combs GF..The Original Bulldog Club ->> The Bulldog Club of Milan ->>To promote and encourage the Breeding of Pure Bulldogs in all of the World, but more especially In the provinces of England, to Ireland, and in Scotland, in Italy, in Lombardy and in Milan.
Honorary President, Ever and Forever, Mrs. D.N. and Mr. Les Thorpe. Bulldog Club, creato per celebrare la incredibile nascita proprio a Milano, per merito esclusivo di Tuffnuts Bulldogs, in collaborazione con il The Bulldog International Research Center e con Ocobo Show Bulldogs, di quelli che, secondo i più profondi studi mondialmente dimostrabili, risulterebbero essere i più diretti discendenti e, quindi, i legittimi eredi di Rosa, il capostipite della Razza Bulldog, con genealogia integralmente inglese, Lincolnshire, Tuffnuts Ocobo. Il Club si è formato, infatti, nel Dicembre 2004 alla nascita di Tuffnuts Snow Angel Tuffnuts, dedicata al Maggiore L.A. Jackson ed a Dr. Les Cotton, il secondo Original Pure Breed Bulldog, nato a Milano ed in Italia dopo Tully, nato nel 2000, sempre nell ' Allevamento Tuffnuts Snow Angel. Per supportare la razza e tutti coloro che possiedono un Bulldog Inglese. Cucciolate disponibli, affidamento bulldogs, problemi di salute, riproduttori disponibili, etc..Il primo Club che si pone l'obiettivo di selezionare ed allevare anche il Bulldog Originale di Razza Pura, come era fino all' inizio del 20° secolo, con una genealogia completamente inglese, discendente dai più famosi Campioni della Storia.
