Artificial rearing necessitates stressful cow-calf separation (Lefcourt and Elsasser, 1995; Hopster et al, 1995) and precipitates cross-suckling (Lidfors, 1993). Thus, suckling systems may improve the welfare of cows and calves, by alleviating 'stressful' cows-calf separation and satiating suckling motivation. The aim of this experiment was to compare behaviour in cows and calves in restricted suckling and non-suckling systems.Thirty six multiparous dairy cows and calves were divided at 4 days postpartum into three groups. The treatment groups were; non-suckled (NS) cows with calves artificially reared (AR), cows suckled by their own calf (RSM) and cows suckled by a foster calf (RSF). Suckling took place for 15 minutes following mechanical milking only.

AbstractInterest in dairy calf rearing systems with cow-calf contact during the milk feeding period is increasing among farmers, advisors and researchers, but socio-economic consequences have only scarcely been investigated yet. In this research reflection we develop a suggestion for a socio-economic methodical framework that is suitable for the wide variation of cow calf rearing systems, farm, market and societal conditions. Based on a literature based, system-theoretical structuring of involved elements, and on full cost accounting in an exemplary case study concerning two model farms, we itemize monetary factors, and additionally important non-monetary factors, that should be included in a socio-economic evaluation. This process also revealed further research needs. We propose as a next research step to gather a greater number of real farm data including different rearing systems and to perform individual full cost accountings, in order to identify input and output patterns on this basis. This might not only help to provide a robust basis for economic decision making, but also help to fill research gaps concerning long-term effects of calf rearing with cow contact. In addition, ways should be explored on how to take non-monetary effects into account.

Abstract. Suckling behaviour of nine beef cow-calf-pairs (Hereford and Charolais) and five dairy cow-calf-pair's (Polish Holstein-Friesian) was video-recorded from day one pp to day 70 (beef) or 82 (dairy) post partum (pp) regularly. Cows were only suckled during that time and milk yield could not be recorded. Bout was defined as all activities of the calf from the first contact between the mouth of the calf at a specific teat and the last contact at this teat, i.e., as a small sub-unit of a meal. Number of suckled teats, uniformity of relative shares of suckled teats, number of bouts, average bout and relative number of bout-teat-repetitions described the course of ontogeny of suckling behaviour. The first model included the effects breed, cow (breed), and day pp as regression. The analysis revealed the following: (i) number of teats, uniformity of relative shares between suckled teats, and number of bouts increased with increasing day pp. (ii) Average bout, relative number of bout-teat repetitions and mealbout- relationship decreased with increasing day pp. (iii) The same developments could be observed in both breeds, however, significantly slower in the dairy breed. The second model included the effects breed, cow (breed) and average bout as regression, representing milk yield. Breed changed from a very powerful into an almost negligible effect in that second analysis. The implications of the results for a wider group of mammalian species are discussed.

Calf Rearing

The effects of twin-foster calf rearing on calf weight at 200, 291 and 365 days postcalving, on calf weight produced per cow, and on reproductive performance of cows were evaluated using fall-born calves. Eleven Holstein × Angus or Holstein × Hereford 2- or 3-yr-old cows rearing 20 Holstein or Limousin crossbred calves were compared with cows of similar age and breeding rearing 13 single-suckled Limousin crossbred calves. Twin calves were significantly lighter than single calves, but calf production per cow at 200 days postcalving was increased 39% by twin fostering. At 291 and 365 days postcalving, production per cow from twin fostering was 50% and 55% greater than that from single-suckled cows whose calves were weaned at 291 days. Twin fostering did not depress reproductive performance of the cows. However, supplemental feed costs and labor required at fostering were considered to restrict applicability of this management practice. Weaning at 9 mo as opposed to 200 days of age increased calf production per single-suckled cow without a substantial increase in costs. Key words: Cow-calf, twin foster, single-suckled, fall calving

Isolation during calving is a common dairy cow behavior, however it has not been examined in large outdoor group settings. The provision of “hides” was monitored for its impact on calving location and cow–calf behavior. Stocking density and bedding management were either controlled (Phase 1) or managed according to farm practice (Phase 2). Hides were used for calving by 18% (Phase 1) and 22% (Phase 2) of the cows; a further 59% and 44% of cows moved into the hides after calving (Phase 1 and 2, respectively). When hides were not available, cows calved near the edges of the calving area. In Phase 2, as stocking density increased, cows tended to use the hides less. Older cows were less likely to isolate regardless of management. Cow–calf interaction with other cows and calves was lower when hides were available. There was no evidence that hides reduced incorrect matching of cows and calves by staff, however cases of “mismothering” (i.e., calves being taken by other dams) were observed. Since the majority of cows used the hides at some stage before or after calving, we suggest opportunities for seclusion should be provided in large calving groups.

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, allogrooming, suckling and cross-suckling, cows' eating and resting behaviour and finally vocal response to separation were assessed. After 3 d in an individual calving pen, pairs (n = 8) were moved to the CCC compartment with a cow area, a calf creep and a meeting area. During the next 31 d calves could suckle the cows whenever they visited the meeting area (suckling phase). Cows had free (group 1, n = 4 pairs) or restricted access to the calves based on previous activity in the automatic milking system (group 2, n = 4 pairs). SG's controlled cow traffic between the meeting area and the cow area, in which the cows could access resources such as feed, cubicles, and the automatic milking system. Following the suckling phase cow access into the meeting area was gradually decreased over 9 d (separation phase). During the suckling phase, cows paid frequent and short visits to their calves. Pairs spent in total approximately one h/d suckling and allogrooming. However, the duration and frequencies of these events varied among pairs and groups, as did the vocal response to separation. Restricted access − cows performed more (unrewarded) attempts to visit the calves who cross-suckled more. Collectively, free access to the calves may have been more intuitive and welfare friendly. Although a low sample size limits interpretation beyond description and enabling hypothesis formulation for future research, the results indicate that the cow is motivated to visit her calf, albeit through a SG, thus facilitating particular behaviours for which cow-calf pairs are highly motivated.

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. With more research in the area, there is a risk of inconsistencies emerging in the use of terminology. To create a better consensus in further discussions, the aim of this Research Reflection is to provide definitions and propose a common terminology for cow-calf contact in dairy production. We also suggest definitions for various systems allowing cow-calf contact and describe the distinct phases of cow-calf contact systems.

Weibull Equation

We describe preliminary attempts to fit a mathematical function to the slow-component eye velocity (SCV) over the time course of caloric-induced nystagmus. Initially, we consider a Weibull equation with three parameters. These parameters are estimated by a least-squares procedure to fit digitized SCV data. We present examples of SCV data and fitted curves to show how adjustments in the parameters of the model affect the fitted curve. The best fitting parameters are presented for curves fit to 120 warm caloric responses. The fitting parameters and the efficacy of the fitted curves are compared before and after the SCV data were smoothed to reduce response variability. We also consider a more flexible four-parameter Weibull equation that, for 98% of the smoothed caloric responses, yields fits that describe the data more precisely than a line through the mean. Finally, we consider advantages and problems in fitting the Weibull function to caloric data.
