Effect of Type of Cow-Calf Contact on Health, Blood Parameters, and Performance of Dairy Cows and Calves [PDF]

open access: yesFrontiers in Veterinary Science, 2022
Prolonged cow-calf contact (CCC) could potentially improve dairy calf welfare. However, it is currently unknown how different types of CCC affect animals' biological functions. We evaluated health and performance parameters of dairy calves and their dams,

Factors contributing to milk yield variation among cows in a cow–calf contact system in early lactation [PDF]

open access: yesJDS Communications, 2022
The conventional dairy production system involves separation of the cow and calf at around 24 h after birth. Due to public concerns regarding this early separation, a few farmers are taking up the cow–calf contact system. However, some farmers have cited

Exploring factors influencing machine milk yield of dairy cows in cow-calf contact systems: Cow behavior, animal characteristics, and milking management [PDF]

open access: yesJDS Communications
The objective of this study was to explore factors contributing to low machine milk yield of cows with cow-calf contact. Danish Holstein dairy cows were assigned to 1 of 3 cow-calf contact treatments: full-time with the calf (n = 24), part-time with the ...

Time budgets of dairy cows in a cow-calf contact system with automatic milking [PDF]

open access: yesJDS Communications
Daily time budgets can be used to determine the amount of time cows allocate to different behaviors throughout the day and can be useful when evaluating housing and management systems. There is a growing interest in keeping dairy cows and calves together

Methods for estimating milk production of dairy cows with full cow-calf contact [PDF]

open access: yesJDS Communications
Dairy cows with full cow-calf contact can nurse their calves and perform maternal behaviors without hindrance. Owing to the unrestricted suckling, the total milk production of the suckled cows (i.e., machine milk yield [MMY] and milk consumed by the calf)

Effect of debonding on stress indicators in cows and calves in a cow-calf contact system [PDF]

open access: yesJDS Communications
Premature separation, entailing a mixture of stressful events, follows a period of cow-calf contact in dairy production. We hypothesized that timing and length of debonding (i.e., gradually adapting cow and calf to separation) may affect behavioral ...

Brief research report: Fertility, teat, and body condition of foster cows in a cow–calf contact system [PDF]

open access: yesFrontiers in Veterinary Science
One alternative to early cow–calf separation is continuous foster cow-calf contact, where one cow nurses two to four calves without being milked. However, multiple sucklings may compromise teat and body condition and affect fertility.

Suckling and allosuckling behavior of dairy calves in indoor dam-rearing systems [PDF]

open access: yesFrontiers in Veterinary Science
An important element in dairy cow-calf contact (CCC) systems is to ensure sufficient milk intake by calves. However, little is known about possible changes in suckling behavior during suckling periods for calves up to 15 weeks old, and the prevalence of ...

Cow-calf contact: a single-herd observational study of AMS yield during the first 100 days in milk [PDF]

open access: yesActa Veterinaria Scandinavica
An increasing number of dairy farmers plan to implement cow-calf contact (CCC) in their herd which necessitates descriptions of the cows` performance in different systems. The aim of the study was to describe (1) Automatic milking system (AMS) milk yield

Maternal contact and age-dependent succession influence the assembly of the calf rumen microbiome and virome [PDF]

open access: yesMicrobiology Spectrum
Early-life colonization of the rumen is particularly important; however, the processes by which microbial and viral communities are transmitted and developed remain poorly understood.
