Feeding behavior and responses in grazing lactating cows supplemented with peanut cake

Abstract

-This experiment was conducted to study the substitution of soybean meal with peanut cake in the supplement by assessing the feeding behavior and the interaction between the thermal environment and the physiological responses of eight crossbred cows with an average live weight of 500 kg. Cows were divided into two 4 × 4 Latin squares and managed on pasture. The peanut cake was included at the levels of 0, 330, 660, and 1,000 g kg −1 in the supplement as a replacement for soybean meal. The feeding behavior variables were not affected by the levels of peanut cake. No differences were found for the physiological parameters of the animals with the replacement of soybean meal for peanut cake in the supplements. Peanut cake can replace up to 100% soybean meal in the supplement of grazing lactating crossbred cows without altering the feeding behavior or physiological parameters of the animals.

Fatty acid profiles of milk and Minas frescal cheese from lactating grazed cows supplemented with peanut cake

“…By-products from the biofuel industry are among the types of food sources that are lower in cost and have potential use in ruminant feed (Oliveira et al 2015b). Furthermore, the inclusion of cakes from palm fruits in ruminant diets has attracted the attention of the scientific community and stimulated research (Costa et al 2015; Silva et al 2015) on the influence of these products on the production and quality of milk and cheese (Oliveira et al 2015b). Peanut cake is a by-product of the extraction of peanut seed oil and has a high nutritional value, particularly in terms of the levels of protein (41–45%) and lipids (8–9%) (Abdalla et al 2008; Oliveira et al 2013; Gonzaga Neto et al 2015).…”

Fatty Acid Profile of Milk and Cheese from Dairy Cows Supplemented a Diet with Palm Kernel Cake

“…The inclusion of cakes from palm fruits in ruminant diets has attracted the attention of the scientific community and stimulated research [3,4,5] on the influence of these new feedstuffs on production and quality of milk and cheese [4,6,7]. Palm kernel cake, a byproduct of this industrial process of Oil palm cultivation ( Elaeis guineensis ), has been used in ruminant feed because it is a low cost supplement in relation to traditional ingredients (corn and soybean), and it has a reasonable total digestible nutrients concentration (65% to 70%) [8].…”

Reabilitação e monitoramento de um grupo de maritacas (Psittacara leucophtalmus Statius Muller, 1776) proveniente de apreensão, em um condomínio de chácaras no Triângulo Mineiro

“…O Conselho de bem-estar de animais de produção de 1967, estabeleceu que os animais em cativeiro devem estar livres: de fome, sede e desnutrição; de desconforto; de dor, injúrias e doenças; para expressar o comportamento natural da espécie; de medo e estresse (Saad et al, 2011), o que corrobora com Broom e Molento ( 2004), em que os efeitos sobre o bem-estar animal devem atuar em diferentes aspectos. Portanto, esse cuidado com os animais não humanos deve ser aplicado em qualquer situação, como na produção para o consumo, produção de trabalhos científicos, manutenção em cativeiro, ou criação como animais domésticos (Costa et al, 2015). De acordo com Webster (2005) O enriquecimento ambiental traz inúmeros benefícios aos animais em cativeiro, como: redução do estresse e, por consequência, da incidência de infecções; menor ocorrência de comportamentos estereotipados; melhoria das habilidades cognitivas e, consequente, melhora no bem-estar psicológico do animal; menor possibilidade de perda de massa óssea, devido à prática de exercícios físicos; melhores condições de lidar com situações imprevisíveis, e aumento de comportamentos exploratórios (Coulton et al 1996;Boom & Molento, 2004, Pizzutto et al, 2009Simões, 2009;Melo et al, 2014;Telles et al, 2015).…”
