Resumo: Na cadeia produtiva de bovinos de corte é reconhecida a importância do comportamento materno para a sobrevivência e o desenvolvimento do bezerro recém-nascido. Neste caso, o sucesso da atividade depende de alguns componentes do comportamento
materno, dentre eles as relações estabelecidas entre a vaca e o bezerro nas primeiras horas após o parto, a aquisição de imunidade pela ingestão do colostro, o suprimento adequado de leite e a proteção ativa da cria contra eventuais predadores. Este último é conhecido como comportamento de proteção materna, que é caracterizado como a reação das vacas frente à presença de potenciais predadores, incluindo humanos. Após o parto, as vacas podem expressar diferentes comportamentos, desde rejeição do bezerro, que representaria uma falha na formação do vínculo natural entre mãe e filho, até comportamentos de proteção materna muito intensos. Alguns procedimentos de manejo importantes para os bezerros são realizados no primeiro dia após o parto, tais como verificar se houve ingestão do colostro, desinfecção do umbigo,
identificação dos bezerros, dentre outros. Se durante esse manejo os vaqueiros são percebidos como potenciais ameaças, uma vaca muito protetora pode expressar comportamentos agressivos em relação a eles na tentativa de proteger sua cria, aumentando o risco de acidentes com ambos, vaqueiro e bezerro. Assim, embora o comportamento de proteção materna seja uma característica desejável, é possível que se torne
um risco para a segurança dos trabalhadores. Nesta revisão será abordada a questão do comportamento de proteção materna em bovinos de corte, sua relação com a reatividade ao manejo, e potenciais implicações no desempenho dos bezerros à luz dos resultados das pesquisas realizadas até o momento. Abstract : In the beef cattle production chain, the importance of maternal behavior for survival and development of newborn calves is recognized. In this case, the business success depends on some components of maternal behavior, among them the establishment of the relationships between cow and calf during the first hours after calving, immunity acquisition through colostrum ingestion, adequate milk supply, and active protection against predators. The latter is known as maternal protective behavior, which is characterized as cow's reaction towards the presence of potential predators, humans included. After calving, cows can express different behaviors, from rejection of the newborn calf, which would represent a failure in natural bond between mother and calf, up to intense maternal protective behavior. Important procedures are undertaken with calves in the first day after calving, such as verification of colostrum consumption, navel disinfection, calf identification, among others. If during these first handling procedures workers are perceived as potential threats, a protective cow can express aggressive behavior towards them as an attempt to protect its offspring, increasing the risk of accidents for both, handler and calf. Therefore, although maternal protective behavior is a desirable trait, it may become a risk to the workers' safety. This review will address the issue of maternal protective behavior in beef cattle, their relationship with reactivity to handling, and potential implications on calves' performance in light of the results of the research conducted until now.

The aim of this study was to evaluate the inclusion of alfalfa grazing during 8 h continuous or partitioned in 2 separated sessions of 4 h after each milking, on nutrient intake, digestibility, ruminal fermentation, feeding behavior, milk production, milk composition, and milk fatty acid profile, in late-lactation cows fed a partial mixed ration (PMR). Twelve dairy cows (193 ± 83 d in milk, 584 ± 71 kg of body weight) were housed in individual outdoor pens and assigned to treatments according to a 3 × 3 Latin square design replicated 4 times. The treatments were as follows: (1) control (T0), cows were fed a total mixed ration (TMR) provided ad libitum 20.0% crude protein (CP), 32.2% neutral detergent fiber (NDF); (2) fed a diet combining a PMR which had the same ingredient composition as the TMR (60% of ad libitum intake) + 1 session of 8 h of pasture (T8), continuous grazing alfalfa (Medicago sativa; 20.6% CP, 35.8% NDF) after the p.m. milking; and (3) PMR (60% of ad libitum intake) + 2 daily sessions of 4 h of access to pasture after each milking (T4+4). The experiment lasted 57 d and was divided into 3 periods of 19 d each. The first 12 d of each period was used for diet adaptation, and the last 7 d was used for data collection. No differences among treatments were observed for any of the productive variables, feeding efficiency, or purine derivatives excretion. Cows in T0 had greater intake and apparent digestibility of dry matter, organic matter, and nonfibrous carbohydrates compared with T4+4 and T8. Compared with T0, alfalfa grazing increased the concentration of C18:1 trans-11 and decreased those of C16:0 and C17:0 in milk fat. Cows in T4+4 consumed 1.1 more kg DM/d of alfalfa and N provided by alfalfa in the diet was 3 percentage points higher compared with T8 cows (266 vs. 229 g/d, respectively). In addition, T4+4 cows had a greater daily range of ruminal pH than T8 (0.73 vs. 0.93), and the highest concentrations of NH3-N were recorded during the a.m. grazing session while in T8 cows it occurred during the night. In conclusion, including 8 h of alfalfa grazing in T8 and T4+4 treatments allowed the substitution between 35.8 and 38.7% of the total dry matter intake (DMI) of a PMR (with a similar CP concentration to alfalfa) for pasture, maintaining milk solids production and increasing the C18:1 trans-11 of milk fat compared with a TMR in mid late-lactation cows. In an herbage plus PMR diet, splitting the 1 continuous grazing session of 8 h into 2 sessions of 4 h increased the proportion of energy and N provided by alfalfa pasture and reduced PMR intake, without modifying the total nutrient intake or productive performance of cows. © 2023, The Authors.
