General Concern

AbstractThe transport of weaned calves from cow–calf producers to fatteners is a general concern for the young bull industry due to its documented negative impact on the welfare, health and performance of the animals. These transfers are often managed by intermediaries who transport weaned calves to sorting centres, where they are grouped into batches before being sent to fattening units. In this study, we present an algorithm to limiting these transfer distances by appropriately selecting the sorting centre through which they must go. We tested the effectiveness of this algorithm on historical data from a French beef producer organization managing 136,892 transfers using 13 sorting centres. The results show a decrease in the transfer distances compared to the historical record, especially for the calves travelling over long distances (− 76 km, i.e. 18% on average for the 33% longest transfers). Moreover, the distribution of calves between the sorting centres proposed by the algorithm reveals differences in their efficiency in minimizing transfer distances. In addition to its usefulness as a management tool for the daily transport of cattle, this algorithm provides prospects for improving the management of the sorting centres themselves.

Abstract The aim of this study was to assess the effects of conditioning, rest, and post-rest transport duration on welfare indicators of 6–7 mo old beef calves. Three hundred and twenty-eight weaned calves (237 ± 29.7 kg BW) were randomly assigned to a 2 × 2 × 2 nested factorial design: conditioning, conditioned (C) or non-conditioned (N); rest, 0 (R0) or 8 (R8) h, and post-rest transport, 4 (T4) or 15 (T15) h. Calves were sampled prior to the first loading (L1), after 20h of transport, prior to and after the additional 4 or 15-h transport, and at 1, 2, 3, 5, 14, and 28 d after transport ended. Data were analyzed using the GLIMMIX procedure of SAS. Fixed effects included conditioning, transport and time nested within rest period, while random effects included animal and pen. Greater shrink (P < 0.01) was observed in C than N calves after the initial 20-h transport. The N calves had greater (P < 0.01) ADG than C calves between L1 and d 5, while C had greater (P < 0.01) ADG than N calves between 14 and 28 d. L-lactate concentrations and flight speed were greater (P ≤ 0.05) in C than N calves between L1 and d 5. The R8-T4 calves had greater (P < 0.01) ADG than R8-T15 calves between L1 and d 5. The R0-T4 calves had greater (P = 0.02) L-lactate concentrations than R0-T15 and R8-T4 calves on d 1. The R0 calves had greater (P < 0.01) ADG than R8 calves between 14 and 28 d. Preliminary results show physiological, behavioral, and performance differences across treatments, however, additional indicators are required to accurately assess the effect of conditioning, rest, and post-rest transport durations on calf welfare.

And Performance

Proper grazing management is the most effective practice to provide adequate forage quantity and quality to cow–calf systems, and optimise beef-calf performance in tropical and subtropical regions. Supplementation of beef calves is not a commonly used management practice in beef-cattle production, primarily because calves can benefit from the cow’s milk production to offset some limitations in forage quantity and quality. Creep-feeding and supplementation of early weaned calves are the two main strategies to supplement beef calves. Creep-feeding can be used to overcome limited herbage allowance, improve calves uniformity, supply extra nutrients for calves, provide adaptation to concentrate diets before weaning, and increase weaning weight. Early weaning is an effective management practice to increase the likelihood of re-breeding of first-calf beef heifers in the south-eastern USA; however, it was observed that concentrate supplementation is necessary for early weaned calves to achieve desirable levels of gain on pasture in tropical and subtropical regions. In addition, concentrate supplementation during early stages of a calf life may permanently change calf development and performance in a process called ‘metabolic imprinting’. The metabolic imprinting concept in production agriculture is in the early stages of knowledge and further research should elucidate the benefits of this management practice in beef-cattle production.

This study assessed the effects of different amounts of supplement on the productive performance, nutrional caracteristics and behaviour of suckling beef calves, as well as on the productive performance of their dams on tropical pastures. Forty-four male Nellore beef calves with an average age of 120 days and an initial average body weight (BW) of 145±3.7 kg and their respective dams, with an average BW of 449±6.9 kg, were used. The amounts of supplement evaluated were as follows: 0 = calves received only mineral mixture ad libitum; 3, 6, and 9 = calves received 3, 6, or 9 g kg-1 BW of supplement, respectively, containing 250 g CP kg-1 (as-fed). The experimental design was completely randomized. A positive linear effect (P < 0.01) was observed in the intakes of dry matter and organic matter, and a cubic effect (P < 0.07) was observed for the intake of neutral detergent fiber corrected for ash and protein. There was quadratic effect (P < 0.06) for total digestibility of neutral detergent fiber. A cubic effect (P < 0.01) was observed for the calves’ performance. However, the calves’ supplementation did not affect the milk yield and performance (P ? 0.21) of their dams. The supplementation decreased grazing time (P < 0.01) but did not influence suckling time (P ? 0.59). It is recommended supplying of supplement containing 250 g CP kg-1 (as-fed) in amount 6 g kg-1 BW to suckling beef calves managed in tropical pasture. Supplementation of suckling beef calves increases the intake of dry matter, decreases grazing time and forage intake. However, it does not affect the suckling time and productive performance of their dams.

Abstract This experiment evaluated the impacts of administering a bovine appeasing substance (BAS) to beef calves at weaning on their performance, physiological responses, and behavior during a 42-d preconditioning program. Eighty calves (40 heifers and 40 steers; 90% British × 10% Nellore) were weaned at 233 ± 2 d of age (day 0); ranked by sex, weaning age, and body weight (BW); and assigned to receive BAS (IRSEA Group, Quartier Salignan, France; n = 40) or placebo (diethylene glycol monoethyl ether; CON; n = 40). Treatments (5 mL) were topically applied to the nuchal skin area of each animal following dam separation. Within treatment, calves were allocated to one of eight drylot pens (four pens per treatment; pen being the experimental unit) and received a free-choice total mixed ration (TMR) from day 0 to 42, intake of which was assessed daily. Live behavior observations were conducted on days 1, 2, 4, 8, 16, and 32. Temperament was assessed and blood samples were collected via jugular venipuncture on days −21, 0, 3, 7, 14, 28, and 42. Hair samples were collected from the tail switch on days 0, 14, 28, and 42. Calves were vaccinated against bovine respiratory disease viruses on days −21 and 0. Average daily gain from day 0 to 42 did not differ between treatments (P = 0.57) but was greater (P = 0.05) in BAS vs. CON calves from day 0 to 28. Intake of TMR was greater (P = 0.05) during the first week for BAS vs. CON calves (treatment × week; P = 0.08). The mean proportion of calves feeding simultaneously and performance of social and play behaviors were greater (P ≤ 0.05) for BAS vs. CON calves. Escape attempts were greater (P &lt; 0.01) for BAS vs. CON calves on day 1 (treatment × day; P = 0.03). Exit velocity was greater (P = 0.04) for CON vs. BAS calves on day 14 and tended (P = 0.10) to be greater for CON vs. BAS calves on day 7 (treatment × day; P = 0.03). Mean plasma concentrations of haptoglobin were greater (P = 0.02) in CON vs. BAS calves. Hair cortisol concentrations were greater (P = 0.05) in CON vs. BAS calves on day 14 (treatment × day; P = 0.03). Mean serum concentrations of antibodies against bovine viral diarrhea virus were greater (P = 0.02) in BAS vs. CON calves. Collectively, BAS administration to beef calves at weaning alleviated stress-induced physiological reactions, improved temperament evaluated via chute exit velocity, enhanced humoral immunity acquired from vaccination, and appeared to have accelerated adaptation to novel management scheme and environment.
