A preliminary study on the feasibility of two different cow-calf contact systems in a pasture-based, seasonal calving dairy system: effects on cow production and health

Animal
Internationally, consumer dissatisfaction with cow-calf separation at birth has led to increased interest in alternative calf−rearing methods, specifically cow-calf contact (CCC) systems.

Perspective: Prolonged cow-calf contact—A dilemma or simply another step in the evolution of the dairy industry?

Journal of Dairy Science
: The contentious issue of cow-calf separation at birth is incongruent with many views on acceptable farming practices, and carries the risk of eroding public trust in the dairy industry if it is not addressed.

Effect of weaning and cow-calf contact on the physiological and clinical health, performance, and behaviour of dairy cows and their calves

Animal
Cow-calf contact (CCC) systems have become increasingly popular calf−rearing systems to promote positive welfare; however, weaning and separation may cause distress.

Growth and metabolism of calves in a dairy cow-calf contact system with gradual weaning and separation

Journal of Dairy Science
: In dairy cow-calf contact (CCC) systems, cows and calves stay together for a prolonged period, allowing for more suckling and strengthening of the maternal bond compared with the early separation of cow and calf in conventional dairy systems.

Methodological terminology and definitions for research and discussion of cow-calf contact systems [PDF]

Journal of Dairy Research, 2020
AbstractDue to increasing public concern regarding separation of the dairy cow and calf within the first days after birth, alternative systems, where cows and calves stay in contact for an extended period, are receiving increasing interest from a broad array of researchers and other stakeholders.

Investigating cow−calf contact in a cow-driven system: performance of cow and calf [PDF]

Journal of Dairy Research, 2021
AbstractIn this research communication we describe the performance of dairy cow−calf pairs in two cow-driven CCC-systems differing in cows' access to the calves through computer-controlled access gates (smart gates, SG). We investigated cows' machine milk yield in the automatic milking system (AMS), calf growth, and intake of supplemental milk and ...

Effects of whole-day versus half-day cow-calf contact on cows’ and calves’ performance

Animal
Cow-calf contact systems (CCCs), where dairy cows nurse their own calves for several weeks while being milked, have some advantages in terms of animal welfare.

Methodology for studying human attitudes and behaviour to cow−calf contact systems [PDF]

Journal of Dairy Research, 2020
AbstractThis position paper describes a common stand on methodology of human attitudes and behaviour that is suitable to use in studies regarding cow−calf contact (CCC) in dairy production, in order to create a common knowledge base and foundation for future recommendations of CCC systems.

A Pilot Study on the Feasibility of an Extended Suckling System for Pasture-Based Dairies

Animals, 2023
This study investigated cow-calf productivity in a 10-week, pasture-based, extended suckling system featuring part-time cow-calf contact and once-a-day milking.

Investigating cow−calf contact in cow-driven systems: behaviour of the dairy cow and calf [PDF]

Journal of Dairy Research, 2021
AbstractResearch is needed on how technology can facilitate cow−calf contact (CCC). This research communication describes the behaviour of dairy cow−calf pairs in two cow-driven CCC-systems differing in cows' access to the calves through computer-controlled access gates (smart gates, SG). Specifically, cow traffic through SG when visiting their calves,
