Abstract Paper aims The objective of this paper is to evaluate the economic, social, and environmental impacts of logistics activities of a dairy producer located in Brazil. Originality The main contribution is to apply a quantitative approach to assessing sustainable logistics in the milk supply chain, serving as a basis for future work on this theme. Research method A single case study of a regional producer of dairy products in Brazil is carried out in this research. A sustainable logistics evaluation model was used that quantitatively measures the impact of transportation, storage (including inventory management and material handling activities), packaging, and acquisition activities in the economic, environmental, and social dimensions. Main findings It illustrates the challenge that a Small Medium Enterprise (SME) will have to expand its logistics actions, aiming to generate benefit to the consumer because of actions in the economic, environmental, and social dimensions. Implications for theory and practice This research expands the literature, as it brings together topics such as sustainability, logistics, supply chain, and agribusiness. The baseline is in the case study with quantitative data that allows us to answer the question of how to be sustainable now, rather than waiting for supply chains to do it first so we can discover it.
Foram avaliados o comportamento, as variáveis fisiológicas e o desempenho de bezerros Holandês e mestiços desmamados em diferentes telas de polipropileno e horas de fornecimento de concentrado. Utilizaram-se 24 bezerros, nove da raça Holandesa (H) e 15 mestiços de Holandês (MH), em piquetes parcialmente cobertos com tela de polipropileno com malha de 70 (S70) e 40% (S40) de sombra, recebendo concentrado em três horários: manhã (M), tarde (T) e dias alternados (DA). Os comportamentos comendo e ruminando deitado foram, respectivamente, mais frequentes no ambiente S70 (34,29 e 11,40%) do que no ambiente S40 (30,18 e 6,76%), indicando maior conforto térmico. Os comportamentos ruminando em pé e em pé foram, respectivamente, mais frequentes no ambiente S40 (6,42 e 40,25%) do que no ambiente S70 (5,24 e 31,18%). A temperatura da superfície do pelame apresentou maior valor no ambiente S40 para os animais H (33,87ºC) e MH (33,69ºC), principalmente nas horas mais quentes do dia, quando a radiação solar era maior. A frequência respiratória foi maior para os animais H tanto no ambiente S40 (55,66 mov. min.-1) quanto no ambiente S70 (60,98 mov. min.-1). O ganho de peso médio diário não variou conforme o fornecimento de ração, de sombra e entre grupos genéticos.
It was evaluated the behavior, the physiological variables and the performance of Holstein calves and crossbred calves weaned using different shade screens and hours of concentrate supplying. There were used nine Holstein calves (H) and 15 crossbred Holstein calves (MH), housed on partially covered paddocks with a polypropylene screen (shade) with a loop of 70% of shadow (S70) and 40% (S40) receiving concentrate at three times: morning (M), afternoon (A) and alternate days (AD). The behaviors eating and ruminating lying were, respectively, more frequent on the environment S70 (34.29 and 11.40%) than on the environment S40 (30.18 and 6.76%), showing greater termical comfort for calves. The behaviors ruminating standing and standing were, respectively, more frequent on the environment S40 (6.42 and 40.25%) than the environment S70 (5.24 and 31.18%). The haircoat surface temperature presented higher values on the environment S40 for animals H (33.87ºC) and MH (33.69ºC), mainly on the hottest hours of the day, where the solar radiation was higher. The respiratory rate (RR) was higher for animals H just about on the environment S40 (55.66 mov. min-1) as much as on the environment S70 (60.98 mov. min.-1). The daily average weight gain did not vary according to the ration supplying, shade and genetic groups.
