Abstract. The welfare of alpacas in farming varies and is influenced by various factors, including environmental conditions, nutrition, interactions with humans, and grooming and breeding practices. It is crucial to provide adequate space for the animals both indoors and in outdoor areas due to their herd-oriented nature. Interactions with humans play a significant role in alpaca farming. Proper handling and gentle treatment positively affect their behavior. However, excessive contact at a young age may lead to undesirable behaviors such as Berserker syndrome. Processes such as birthing, weaning, shearing, as well as other breeding practices, impact the welfare of alpacas. Understanding the animal natural needs and minimizing stress are essential to providing optimal living conditions for them.

Abstract. Domestic goose is a species strongly associated with the agricultural landscape, tradition and culture of local communities. Currently, a unique collection of 14 breeds of geese kept on four farms across the country is included in the programme for the protection of the goose population in Poland. Endangered geese are protected using an in situ method - keeping live animals in their natural environment. All goose breeds included in the protection programme represent a valuable part of the genetic diversity of the species. Based on the analysis of the results for the 2021 or 2022 period, it was found that these geese maintain good health, achieve good production and hatchability parameters, and their mating method protects them from an inbred increase.

Abstract. Pig production profitability is dependent on a number of factors that determine the extent of expenses incurred, taking into account the prices of slaughter animals, the production system and the prices of cereals included in compound feed. However, the most crucial factor is the cost of pig feeding. The aim of this work was to assess the impact of partial replacement of protein concentrate with legume seeds in complete feeds on pig growth rate and fattening efficiency under rearing conditions of a conventional farm. The polish breed crossbred fatteners were divided into two groups with different composition of the fed feed mixture. The analysis covered fattening characteristics and slaughter characteristics. In addition, the value of sales and cost of pig feeding were analysing. In this study, the fatteners fed a feed mixture with legume seeds had higher warm carcass weights, thinner backfat, and higher carcass meat content compared to pigs from control group, which ultimately translated into higher profit on fattener production. A minimum proportion of legume seeds in a feed mixture for pigs has been shown to have a significant impact on growth rate and slaughter value.
