Book Description
This study examined fenceline contact between beef calves and cows at weaning and the subsequent comparisons for behavioral distress and related reductions in weight gain. Eighty-seven crossbred calves were randomly assigned to 3 treatment groups for eight weeks. Six replications were conducted to determine the effect of different weaning techniques on their subsequent growth while three replications were observed for behavioral differences. Treatments were 1) fenceline separation from dams for one week, 2) fenceline separation from dams for two weeks, and 3) total separation (abrupt weaning) from their dams. Calves were weighed on the day of weaning and at 7, 14, 35 and 56 days post-weaning. In the days following weaning, the one-week fenceline weaned calves spent more time eating (eating hay) than either the total separation or two week fenceline weaned treatments (P

Book Description
To assess the effects three different weaning methods have on beef calves' weight gain and behavior, 339 Angus and Angus-cross calves were weaned in 5 trials over 2 years. In each trial calves were equally divided into 3 weaning method treatments: traditional weaning, interval weaning, and fence-line weaning. Behavioral observations began on day 1 and continued to day 5 and included the observation of eating, drinking, walking, standing and lying down behaviors as well as the measurement of the amount of vocalizations emitted by each treatment group. Weights were obtained on days 0, 7, 14, and 28 and average daily gain (ADG) as well as cumulative weight gain was calculated for each period. Fence-line weaned calves vocalized more than interval weaned calves in the evenings (P = 0.02) but no other significant differences were seen. Interval weaned calves were observed eating more than traditionally weaned calves (P = 0.001). Fence-line calves did not differ from the other 2 groups in eating behavior. Traditionally weaned calves spent more time walking than interval weaned calves (P = 0.007). Fence-line weaned calves did not differ from traditionally weaned calves in walking behavior except on days 2 and 3 when they walked less (P = 0.0001 for day 2, P = 0.01 for day 3). Fence-line and interval weaned calves did not differ in walking behavior. Fence-line weaned calves spent more time lying down than traditionally weaned calves (P = 0.006) but no difference was seen between interval weaned calves and the other 2 groups. Fence-line weaned calves did not differ from the other 2 treatments for weight gain data. Interval weaned calves had a greater ADG on week 1 than traditionally weaned calves (P = 0.0003) but traditionally weaned calves had a greater ADG for week 2 than interval weaned calves (P = 0.002). For cumulative weight gain, interval weaned calves had greater weight gain than traditionally weaned calves for the 0 through 7 day period but weight gain did not differ between any of the three treatments for the 0 through 14 day period or the 0 through 28 day period. It was concluded that fence-line weaning provided minimal benefits to calf behavior during weaning and no benefits to weight gain compared to traditional weaning where as interval weaning provided benefits to behavior and weight gain during the first week of weaning compared to traditionally weaning making it a likely candidate to replace traditional weaning especially when calves are marketed the week after weaning occurs.

Book Description
Contains a selection of White Papers, commissioned to better inform the exploration of cattle welfare. These are prepared by notable experts in their field, to help provide factual context around selected topics that impact cattle welfare and production systems. Covers all aspects of cattle use in an accessible style, making this a must have volume for anyone interested in cattle welfare or cattle medicine. Provides an in-depth picture of the distinctive beef and dairy cattle welfare practices and issues, covering topics such as behavior, breeding and genetic manipulation, nutrition and feeding, housing and management, health and disease, and transport and slaughter. Written by acknowledged leaders in animal science, veterinary science, philosophy and animal welfare, presenting a truly multidisciplinary perspective on cattle welfare. Includes a section on understanding and managing animal welfare in both beef and dairy cattle, discussing how cattle perceive the world, animal handling and pain mitigation, and how to assure that the cows have a reasonably good life. The Welfare of Cattle offers an accurate, detailed account of the ethical and welfare concerns related to the human use of cattle. There is currently no significant book dealing with the welfare of cows, animals often seen as archetypal paradigms of 'farm animals'. Covering both beef and dairy cattle, the expert authors provide in-depth information on the husbandry roots of traditional agriculture, the replacement of this system of stewardship by an industrial model, and the resulting welfare challenges associated with industrial agriculture: feedlots, highly industrialized dairies, and slaughterhouses killing huge numbers of animals who have been transported great distances. This important book explores in detail the ways in which people who are providing care for cattle can take their first step, or their next step, toward enhancing the welfare of these animals.

Book Description
Two experiments examined growth performance and physiological measures of stress in pre- and postweaned Angus steers (313 ± 24.5 kg; n = 48/Exp.), where steers were fitted with (YD) or without (ND) an anti-suckling device (Exp. 1), or provided (YS) or not provided (NS) a supplement (Exp. 2) for 7 d and weaned (d 7) by fenceline (FS) or total separation (TS). Steers in Exp. 1 were weighed and bled on d 0, 3, 7, 10, 14, 21, and 42, and in Exp. 2, on d 0, 7, 10, 14, and 21 and provided a supplement on d 7-21. In Exp. 1, weight gain was not different (P = 0.74) between ND and YD steers during preweaning. The YD-FS steers lost weight (P = 0.01) by d 10 compared with YD-TS steers. Hematocrit (Hct) increased (P = 0.04) in YD but not ND steers on d 3. Neutrophil:lymphocyte (N:L) ratio increased (P
