Modelling the lactation curve of dairy cows using the differentials of growth functions [PDF]

open access: yes, 2008
Descriptions of entire lactations were investigated using six mathematical equations. comprising the differentials of four growth functions (logistic. Gompertz, Schumacher and Morgan) and two other equations (Wood and Dijkstra).

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Estimation of Genetic Parameters for Milk Production Rate and Its Stability in Holstein Population

open access: yesAnimals
Milk production rate (MPR) refers to the rate of milk secretion per hour (kg/h), calculated from the harvested milk yield and milking interval, and it is considered an appropriate measure to evaluate the production potential of cows.

Genetic relationship between weaning weight and milk yield in Nguni cattle

open access: yesAnimal, 2018
A study was conducted to estimate the genetic relationship between weaning weight and milk yield in Nguni cattle. Milk yield data (n=125) were collected from 116 Nguni cows from Mara Research Station located in Limpopo Province and Loskop South Farm ...

Effect of forage legumes on feed intake, milk production and milk quality – a review [PDF]

open access: yes, 2010
Literature data from experiments with lactating dairy cows offered silage-based diets was reviewed to evaluate the effects of the grassland legume species Trifolium repens (WC, white clover), Trifolium pratense (RC, red clover) and Medicago sativa (M ...

Measurement of Liner Slips, Milking Time, and Milk Yield

open access: yesJournal of Dairy Science, 1996
Liner slip or rapid air leakage past the mouthpiece of the milking machine liner is related to high rates of new cases of mastitis. A real time technique was developed to monitor the air flow into the milking machine cluster during liner slips as well as to monitor milking time and milk yield using a commercial type pipeline milking system.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

open access: yesMolecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Hubungan Masa Kosong dengan Produktivitas pada Sapi Perah Friesian Holstein di Baturraden, Indonesia

open access: yesMedia Peternakan, 2011
Productivity of dairy cows not only expresed by milk yield, but also the reproductive performance. General speaking that the milk yield depends on reproductive performance and vice versa.

Estimation of the Genetic Parameters for Test-Day Milk, in Teleorman Black Head Sheep

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The objective of this study was to determine the genetic parameters represented by heritability for test-day milk yield and the genetic correlation between test-days milk yield and the breeding value for Teleorman Black Head sheep. The genetic parameters

Response profiles of dairy cows to a single 24-h milking interval in relation with milk proteolysis, udder expansion and immune traits

open access: yesAnimal, 2019
An extended milking interval of 24 h (24-h milking interval (24h-MI)) constitutes the acute phase of cow adaptation to once-daily milking (ODM). A recent trial including 724 24h-MI challenges demonstrated that milk yield responses to this acute phase of ...
