乳中含有2%~5%的脂质,乳中的脂质由乳腺上皮细胞分泌并以乳脂肪球的形式分散在乳中。大部分乳脂(约98%)以甘油酯的形式存在于乳脂肪球内部,其余(约2%)包括甘油磷脂、鞘脂、糖脂等在内的少部分极性脂质则主要分布在乳脂肪球膜表面。乳极性脂质虽然在乳脂中占比较少,但却对哺乳动物的生长发育有着不可或缺的作用。本文首先介绍乳中极性脂质的种类,比较奶牛乳、水牛乳、牦牛乳、绵羊乳、山羊乳、驴乳、骆驼乳、人乳等不同乳源的乳极性脂质种类及含量差异,随后探讨乳极性脂质的生理功能,包括抑制中性脂肪吸收、调节肠道微生物群落组成、预防心血管疾病、预防非酒精性脂肪肝、促进认知功能与神经系统发育、抗炎作用等,以期为功能性乳脂产品的研发提供参考。

The first search for the doubly heavyΩ^(0)_(bc)baryon and a search for the E^(0)_(bc)baryon are performed using pp collision data collected via the lHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^(-1).The baryons are reconstructed via their decays to Λ^(+)_(c)π^(-)and E^(+)_(c)π^(-).no significant excess is fbund for invariant masses between 6700 and 7300 MeV/c^(2),in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ω^(0)_(bc)and E^(0)_(bc)production cross-section times the branching fraction to Λ^(+)_(c)π^(-)(E^(+)_(c)π^(-))relative to that of the Λ^(0)_(b)(E^(0)_(b))baryon,for different lifetime hypotheses,at 95%confidence *** upper limits range from 0.5 x 10^(-4)to 2.5 x 10^(-4)for theΩ^(0)_(bc)→Λ^(+)_(c)π^(-)(E^(0)_(bc)→Λ^(+)_(c)π^(-))decay,and from 1.4x 10^(-3)to 6.9 x 10^(-3)for theΩ^(0)_(bc)→E^(+)_(c)π^(-)(E^(0)_(bc)→E^(+)_(c)π^(-))decay,depending on the considered mass and lifetime of theΩ^(0)_(bc)(E^(0)_(bc))baryon.

为提高大恒肉鸡S06M系的选择效率,对其选育的遗传进展进行分析。结果表明:目前已开展的6个世代选育对S06M系主要性状的选择有效,特别是生长速度的选择对繁殖性能未造成不利影响,表现为繁殖性能的各项指标在选育中均取得不同程度的进展,特别是68周产蛋量进展明显。虽然在第2个世代后选育进展明显降低,但依然保持在较高的水平,同时性状趋于稳定。
