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.

Effects of peripartum biotin supplementation of dairy cows on milk production and milk composition with emphasis on fatty acids profile [PDF]

open access: yes, 2008
Forty Holstein dairy cows receiving a 38% concentrate diet based on maize silage were assigned to either a control group, either a biotin group, receiving 20 mg of biotin per day from 15 days before expected calving date and for 120 days after calving ...

RELATIONSHIP OF UDDER AND BODY MEASUREMENTS WITH MILK IELD IN HOLSTEIN COWS REARED IN EGYPT [PDF]

open access: yesFayoum Journal of Agricultural Research and Development, 2019
The aim of the present study was to study the relationship of udder and body measurements with milk yield in Holstein cows in Egypt. Milk yield, udder and body measurements were recorded using 10 Holstein cows in first and second parity.

Whole-crop cereals in dairy production [PDF]

open access: yes, 2008
The four studies summarised and discussed in this thesis evaluate the use of whole-crop cereal silage (WCCS) for cattle in dairy production. The dry matter (DM) yield, chemical composition, digestibility, feed intake and milk production for WCCS were ...

Evaluation of reference lactation length in Chios dairy sheep

open access: yesAnimal, 2019
Definition and establishment of a fixed reference lactation length could provide useful tools for on-farm comparison of ewes and flock management as well as genetic evaluations for the breeding programme. The objectives of this study were to (i) evaluate

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

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 ...

Characteristics of milk production traits of Balkan goats raised under “low-input” production systems

open access: yesMljekarstvo, 2010
In order to analyse dairy production traits (milk yield in full lactation, milk fat content, daily milk yield and length of lactation) of Balkan goats raised under “low-input” production systems, data on 440 lactation records from 118 does raised on 9 ...

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 ...
