This study was to investigate growth performance, rum.nation developm.nt, rum.n ferm.ntation and feed digestion in young calves provided high volum.s(about 20% of calf birth weight) of m.lk with or without forage inclusion and how these param.ters correlate with each other. Im.ediately after birth,160 newborn Holstein female calves(41.6 ± 4.2 kg of initial BW) were random.y divided into 2 treatm.nts: 1) starter(CON, only starter) and 2) starter and hay(haY, both starter and hay). The calves were fed their respective experim.ntal diets from.d 4 to 84, after which they were all introduced to sim.lar diets until the end of the experim.nt on d 196. Treatm.nt had no effect on growth and structural m.asurem.nts throughout the experim.ntal period. However, treatm.nt had an effect on the other param.ters, mainly during the post-weaning period. Forage supplem.ntation tended to reduce starter dry matter intake(P = 0.05), while increasing the forage intake(P haY calves had increased neutral detergent fiber(NDF) and physically effective NDF(peNDF)intakes(P m.ared to CON calves.

A Note on P m.Factorizable Topological Groups

Journal of mathematical Research with Applications 2024年第2期44卷 209-212页

作者： Chunjie ma Liangxue PENG Beijing University of Technology School of mathematics Departm.nt of mathematics Statistics and m.chanics

In this paper, we define a new class of P m.factorizable topological groups. A topological group G is called P m.factorizable if, for every continuous function f : G → m.to a m.trizable space m. one can find a perfect hom.m.rphism.π : G → K onto a second-countable topological group K and a continuous function g : K → m.such that f = g■π. We show that a topological group G is P m.factorizable if and only if it is P R-factorizable. And we get that if G is a P m.factorizable topological group and K is any com.act topological group, then the group G × K is P m.factorizable.
