Newborn calf welfare: A review focusing on mortality rates Tập 84 Số 2 - Trang 101-105 - 2013
Katsuji Uetake
AbstractCalf mortality control is vitally important for farmers, not only to
improve animal welfare, but also to increase productivity. High calf mortality
rates can be related to larger numbers of calves in a herd, employee
performance, severe weather, and the neonatal period covering the first 4 weeks
of life. Although the basic premise of preventing newborn calf mortality is
early detection and... hiện toàn bộ
Impact of restricting feed and probiotic supplementation on growth performance, mortality and carcass traits of meat‐type quails Tập 90 Số 10 - Trang 1388-1395 - 2019

AbstractThe objective of this study was to evaluate the effects of quantitative
feed restriction, along with dietary supplementation with a probiotic blend
(Protexin) as a natural growth promoter, on the performance, water consumption,
mortality rate and carcass traits of meat‐type quails. A total of 250 1‐day
unsexed quails were randomly allocated to five equal groups in a completely
randomized d... hiện toàn bộ
Silage fermentation and ruminal degradation of stylo prepared with lactic acid bacteria and cellulase Tập 88 Số 10 - Trang 1531-1537 - 2017
Mao Li, Hanlin Zhou, Xuejuan Zi, Yimin Cai
AbstractIn order to improve the silage fermentation of stylo (Stylosanthes
guianensis) in tropical areas, stylo silages were prepared with commercial
additives Lactobacillus plantarum Chikuso‐1 (CH1), L. rhamnasus Snow Lact L
(SN), Acremonium cellulase (CE) and their combination as SN+CE or CH1 + CE, and
the fermentation quality, chemical composition and ruminal degradation of these
silages were s... hiện toàn bộ
Protective effects of melatonin on the in vitro developmental competence of bovine oocytes Tập 89 Số 4 - Trang 648-660 - 2018
Yunwei Pang, Shanjiang Zhao, Yeqing Sun, Xiaolong Jiang, Haisheng Hao, Weihua Du, Huabin Zhu
AbstractThe present study investigated the effects of melatonin on bovine oocyte
maturation and subsequent embryonic development in vitro. Results showed that
the nuclear and cytoplasmic maturation, characterized by first polar body
extrusion, normal distribution of cortical granules and mitochondria, as well as
increased mitochondrial membrane potential, were significantly improved in
10−9 mol/L ... hiện toàn bộ
Quantitative expression of candidate genes affecting eggshell color Tập 85 Số 5 - Trang 506-510 - 2014
Chuanwei Zheng, Ze‐Sheng Li, Ning Yang, Zhonghua Ning
AbstractThere are three pigments that affect the color of an eggshell:
protoporphyrin, biliverdin and biliverdin‐zinc chelate. Protoporphyrin is the
main pigment in brown and light‐brown eggshells, whereas very little
protoporphyrin is found in white eggshells. Eggshell protoporphyrin is derived
from the heme formation in birds. Coproporphyrinogen III oxidase (CPOX) and
ferrochelatase (FECH) repre... hiện toàn bộ
Kaempferol alleviates the reduction of developmental competence during aging of porcine oocytes Tập 90 Số 11 - Trang 1417-1425 - 2019
Xuerui Yao, Hao Jiang, Yinghua Li, Qingshan Gao, Nianyin Zeng, Nam‐Hyung Kim
AbstractKaempferol (KAE) is a natural flavonoid present in different plant
species and exhibits anti‐inflammatory, antioxidant, and anticancer therapeutic
properties. In the present study, we investigated the influence and underlying
mechanisms of KAE supplementation on porcine oocytes during in vitro aging. The
results show that KAE treatment can alleviate the aging‐related reduction of
developme... hiện toàn bộ
