This study developed an innovative fish burger using Atlantic bonito, an abundant but undervalued species rich in lipids and protein. The burger was enriched with chickpea, seaweed (Spirulina and Fucus vesiculosus), and hydrocolloids (xanthan and carrageenan). Using a Taguchi design, the effects of varying concentrations of these ingredients on the physicochemical properties, texture, phenolic content, and anti...
Rearing entire male pigs presents several benefits, including enhanced feed efficiency, reduced environmental impact, and improved animal welfare. However, the risk of boar taint poses a significant challenge to pork quality. The objective of this pilot study is to evaluate growth performance, meat quality and the incidence of boar taint in intact male pigs of the Bısara breed (BI) and a terminal cross (TC). Fi...
Managing boar taint involves addressing welfare concerns related to castration, understanding the compounds causing the taint, and developing reliable detection methods. Surgical castration of piglets is common but raises welfare issues, prompting calls for alternatives. The European Union has seen slow progress in banning castration without pain relief, with varying national approaches. Boar taint, caused by a...
Fish is a highly nutritious food, rich in protein, unsaturated fats, vitamins, and minerals, and its consumption has increased due to the associated health benefits. However, fish processing generates substantial waste, accounting for more than 50% of the total weight of the fish, leading to economic losses. Utilising these byproducts presents an opportunity to reduce waste while enhancing the nutritional profi...
Boar taint is an unpleasant odour found in the carcasses of entire male pigs, resulting from androstenone and skatole accumulation during pubertal development, and impacting pork quality. This study proposes the validation of an adapted chromatographic method for quantifying skatole and androstenone in the pigs’ liquid fat using fluorescence detection. A good chromatographic separation was achieved, with skatol...
Immunocastration can be an alternative to surgical castration in Bísaro pigs when there is a need to keep animals on the farm until at least 8 months old. As an autochthonous breed, some particularities must be addressed when doing immunocastration, for which 3 different protocols were tested and two control groups were made with surgically castrated males (SC) and boars (Bo). Two protocols were made in prepube...
Food security is a core global sustainability challenge and priority of the UN Sustainable Development Goals. Events like COVID-19, extreme weather, and global conflicts have significantly impacted food prices, as evidenced by the FAO food price index rising from 95.1 in 2019 to 143.7 in 2022, heightening EU food security concerns. The European Commission responded with a food supply contingency plan. According...
Aim of study: To assess the boar taint prevalence in the Portuguese pork industry through an observational study model by measuring skatole and androstenone levels in fat and to compare it with the estimated thresholds for these compounds among Portuguese consumers. Area of study: Portugal. Material and methods: Adipose tissue samples from 140 animals (102 entire males and 38 females) were collected in three Po...
Traditional outdoor pig farming is renowned for its emphasis on animal welfare and the production of highly valued, quality meat. While seasonality is known to impact certain animals, particularly those raised outdoors, there is a lack of research on Bísaro boars, a native Portuguese breed. This research study was conducted on a total of 20 male entire Bísaro pigs, reared in outdoor pens from 4 to 13 months old...
Background: Mastitis is the most important disease in dairy cattle with impact in welfare of animals and the economy of the dairy farming activity. Attempts have been made to produce vaccines to prevent the disease, however, resultshave been dubious. Aim: The aim of this study was to evaluate the efficacy of the mastitis vaccination in dairy cattle by merging several trials to allow evidence synthesis. Methods:...
