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...... 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 gr...... hiện toàn bộ Protective effects of melatonin on the in vitro developmental competence of bovine oocytes Tập 89 Số 4 - Trang 648-660 - 2018

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 me...... hiện toàn bộ Quantitative expression of candidate genes affecting eggshell color Tập 85 Số 5 - Trang 506-510 - 2014

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 ... hiện toàn bộ Kaempferol alleviates the reduction of developmental competence during aging of porcine oocytes Tập 90 Số 11 - Trang 1417-1425 - 2019

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 agi...... hiện toàn bộ
