Effects of pregnancy on daily milk yield of Holstein–Friesian dairy cattle

Livestock Production Science, 2004
First, second and third lactation curves of 21,885 first lactation dairy cows were allowed to vary depending on the months in milk at which the cow became pregnant. The curves were modelled using a 4th degree polynomial of days in milk. In the models for second and third lactation daily yield, days open in the previous lactation was included as a ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Effect of improving management system on camel milk production [PDF]

, 2015
Twenty four lactating she-Camels of the Sudanese Kabbabish breed and were divided into two equal groups of 12 animals. The first group was managed in a semi intensive system by offering concentrates and roughage, free access to water and veterinary care.

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

ASSESSMENT OF PERSISTENCE COMPONENTS OF MILK FROM SIMMENTAL COWS-HEIFERS OF DIFFERENT ORIGIN [PDF]

Russian Journal of Agricultural and Socio-Economic Sciences, 2014
It was found that the persistence of milk components positively correlated with the dynamics of daily milk yield per lactation. Mass fraction of fat and protein in milk reached lows in mid-lactation, while the time of launch in protein content were ...

Estimation of daily milk yield of Nellore cows grazing tropical pastures

Tropical Animal Health and Production, 2018
Beef cows' milk yield is typically determined by measuring milk yield once daily and then doubling this value to estimate daily production. However, it is not known whether this is accurate. Thus, we aimed to determine the association between morning and afternoon milk yield in grazing Nellore cows. Eighty Nellore cows were used, with initial weight of

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

Advanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess
