Milk Replacers and Bovine Spongiform Encephalopathy in Calves, Japan
infection raise questions about the real pathogenic role of these viruses. As with other polyomaviruses, WUPyV and KIPyV could establish persistent and latent infections with likely asymptomatic reactivations (5), and detection of these viruses could also refl ect a long-term shedding from previous acute episode. Recently published studies have not shown a pathogenic role for these new polyomav...
متن کاملffects of Using Wheat Gluten and Rice Protein Concentrate in Dairy Calf Milk Replacers
There is a limited amount of peer reviewed data on feeding milk replacers (MR) containing either hydrolyzed wheat gluten (HWG; 80% CP) or rice protein concentrate (RPC; 80% CP) to calves under 2 mo of age. Male Holstein calves less than 7 d old from multiple farms (trial 1) and 2to 3-d-old calves from one dairy farm (trials 2 and 3) were used. Trial 1 compared feeding 0.454 kg/d of 20% CP, 20% ...
متن کاملProtein and fat sources for intensive milk replacers
Many dairy producers and calf growers evaluate milk replacers on the basis of cost without considering what value is received for the dollars spent. When someone sells a milk replacer at substantially lower prices than the competition, producers are confused and can’t see why prices differ so much. Frequently the old adage, “if something sounds too good to be true, it probably is” fits well in ...
متن کاملThe Limiting Sequence and Proper Ratio of Lysine, Methionine and Threonine for Calves Fed Milk Replacers Containing Soy Protein*
The limiting sequence and relative ratio of lysine (Lys), methionine (Met), and threonine (Thr) for calves about 2 mo of age fed milk replacers (MR) containing soy protein are not clearly defined. The objective of the study was to investigate the effect of supplementing MR containing 22% CP, half from soy protein concentrate (SPC, 40.56% CP, flour) and half from whey proteins, with Lys, Met, an...
متن کاملGrowth and body composition of dairy calves fed milk replacers containing different amounts of protein at two feeding rates.
Previous research has demonstrated that increasing the CP concentration from 16 to 26% in milk replacers fed to male preruminant dairy calves at 1.5% of BW (DM basis) daily resulted in increased ADG, G:F, and deposition of lean tissue. However, the effects of dietary CP would be expected to vary depending on ME intake. Here, male Holstein calves < 1 wk old were used to determine the effects of ...
