Given the growing concern in recent years for a healthier diet, attention must also be directed towards improving the quality profile of meat products and transforming them, as much as possible, into functional foods that combine the benefits of plant-based products with those of animal-origin products. With this in mind, we aimed to develop a functional meat product, given the recent scrutiny these products have faced, by using an oil with antioxidant effects to enhance the antioxidant profile of products with insignificant endogenous antioxidant levels. To achieve this, three batches of pork tenderloin were injected with 1%, 3%, and 5% sea buckthorn oil, and were analyzed in terms of antioxidant capacity, physicochemical and microbiological quality, and sensory perception. Most results showed highly significant differences (p < 0.001) between batches, with superior quality observed in the batch injected with 5% sea buckthorn oil and subjected to heat treatment. However, consumers preferred the batch injected with 3% sea buckthorn oil due to its more balanced taste. This research underscores the potential to develop meat-based functional foods with enhanced nutritional benefits.

Trichinosis is a disease caused by a nematode parasite of the genus Trichinella spp. This zoonosis has been a major public health problem in many countries. The main source of infection in our country is the domestic pig. It is contaminated by eating food scraps containing raw meat infested with Trichinella spp., eating rats, mice or their droppings or by contact with wild animals. Secondary sources of infection are wild boar and bear. Humans get sick after eating meat infested with larvae enclosed in muscle tissue, insufficiently cooked, curd, roast or smoked. The difficulty in establishing the diagnosis is due to the fact that this disease does not manifest itself clinically and does not present pathognomonic signs and the parasite and its larvae are not visible to the naked eye. The main diagnostic method is represented by the trichinelloscopic examination performed by the veterinarian from a sample of meat collected from certain areas, mainly from the diaphragmatic pillars. In humans, the clinical manifestations are represented by fever, diarrhea, muscle pain, facial edema, eye hemorrhages - retinal and subconjunctival and subungual. All organs, meat and by-products obtained from pigs infected with Trichinella spp. are forbidden to be consumed and are destroyed by burning.

The present study investigates the chemical composition of seeds from Foeniculum vulgare (fennel), Trigonella foenum-graecum (fenugreek), and Cuminum cyminum (cumin) to assess their suitability as food supplements for enhancing milk production in cows. The dry matter, ash content, total nitrogen, total carbon, protein and fiber levels were analyzed to provide comprehensive insights into the nutritional value of these seeds. The experiments in this study were all conducted in triplicate. Results were defined as mean values ± standard deviations. The results are part of a larger project and these findings are integral to the broader project, which aims to develop optimized dietary supplements for dairy cattle. Considering the essential role of nutrition in dairy cattle health and milk production, the identified nutritional components in these seeds hold promise for incorporating them into cattle diets.

This work aims to evaluate the impact of sodium erythorbate (C6H7NaO6) in different amounts (0.05%; 0.1%) on physicochemical quality parameters in a functional product with heterogeneous structure. We aimed to test two main anatomical areas used in the process of obtaining the finished product: Musculus gluteus maximus and Musculus longissimus dorsi from Sus scrofa domestica. Data distribution was evaluated using SPSS Statistics 26.0 software. Multivariate Analysis of Variance (MANOVA) is used to determine if there are significant differences between the amounts of C6H7NaO6 and anatomical area on physicochemical parameters considering their interactions. Pearson correlation was used to analyse the degree of association between the amounts of C6H7NaO6, the anatomical zone, and the physicochemical quality parameters of the finished product. Based on the results obtained, recommendations can be made on the optimal concentration of C6H7NaO6 % to achieve the desired effects on physicochemical quality parameters without compromising consumer safety.

Consumer demand for functional yogurts has been rising recently, particularly for those made by adding plant-based ingredients or their bioactive components. Grape, Vitis vinifera L., is abundant in antioxidant-rich phenolic compounds and dietary fiber. Although grape pomace is an agro-industrial by-product and its handling can lead to socioeconomic and environmental issues, it can be possible to valorise by extracting its bioactive components. The goal of this study was to develop functional yogurt by adding 1 and 2% of grape pomace (YGP1 and YGP2). The impact of fortification was assessed on the enhanced yogurts' physicochemical properties, total phenolic content, antioxidant activity, and sensory acceptance. Grape pomace powder had high total polyphenols contents (20.39 ± 0.23 mg GAE/g d.w.) and antioxidant activity (88.16 ± 0.45%). Values of polyphenols (8.88± 0.06 mg GAE/g d.w.) and antioxidant activity (89.47 ± 0.39%) significantly increased in fortified yogurts compared to control sample. Therefore, it is possible to conclude that grape pomace powder can be used to produce novel, functional yogurt.

The fatty acid composition of 24-hour white brined cheese produced from goat's milk from three groups of animals- Bulgarian White Dairy (BWD) breed and its crosses with Anglo-Nubian (BWD x AN) and Togenburg (BWD x TG) breeds during the lactation and the fatty acid composition of the milk fat of the product has been evaluated as a healthy source for human nutrition. Goat white brined cheese at the 24th hour after production, from the three groups of animals is characterized by a high level of saturated fatty acids from 75.52 g/100 g fat at BWD to 76.09 g/100 g fat at BWD x TG breed. MUFAs predominate in purebred goat cheese- 24.98 g per100 g fat and MUFA in the crosses of BWD x AN breed- 3.32 g/100 g fat. The lipid preventive score is highest in BWD cheese - 53.85 g per 100 g cheese, and the atherogenic and thrombogenic index in BWD x TG breed cheese respectively 2.60 and 2.71. The analysed cheeses at the 24th hour from three goat groups is defined as having low content of TFA according to Regulation (EC) No1924/2006.

One of the breeding objectives for Shagya Arabian breed in Rădăuți Stud Farm, Romania, focuses on increasing the height at withers for mares. The current research aimed to study the entire female progeny (175 foals) of 58 broodmares and 44 stallions included in the breeding activity for 40 years The objective was to determine the influence of breeders’ height and the foaling number (rank) on the foals’ biometrics. The average value of this measurement in female foals has consistently increased from first foaling (157.63 cm) to the fifth one (158.80 cm) throughout 40 years of breeding, indicating the fulfilment of the breeding goal over consecutive reproductive seasons. According to the simulation based on the linear trend equation, the progeny's height at withers could match the fathers' height by the 10th foaling if the same breeding practices were continued. In addition, stallions would have much more influence than broodmares in increasing the height of the foals. Continuing the forecast analysis based on the variations, the required average height at withers values in stallions and mares can be computed to attain a certain value for the descendants.

Following the slaughtering and processing of animals for meat, only one-third of them is meat, while the remainder consists of byproducts and waste, which need to be processed and utilized appropriately. Industrial byproducts constitute costly losses for these industries and pose challenges in their eco-friendly disposal. These costs can be offset through innovation to generate value-added products that increase profitability. Efficient utilization of byproducts has a direct impact on the economy and the environment. This study explores the potential to create collagen-rich bone broths and to this end, four batches were developed, two made from bones sourced from adult cattle and two from bones sourced from juvenile cattle. These were analyzed physicochemically and microbiologically to characterize them qualitatively. The findings suggest that both types of bone broths offer significant nutritional value, with variations influenced by the age of the cattle and the vegetable additions, as evidenced by highly significant differences (p < 0.001) among batches obtained through statistical processing. These findings underscore the importance of efficiently exploiting resources and the potential to develop valuable food products from seemingly residual sources.

Alternative protein sources to replace fish meal in aquaculture feeds are continuously sought after. The fish meal industry is unsustainable, from an economic point of view and because of its impact on wild aquatic ecosystems. This review presents the use of gastropod species (class Gastropoda) in aquaculture feeds. Gastropods have been studied for their potential use in aquaculture feeds, mainly as an alternative source of protein to fish meal. Gathered studies from various databases encompass gastropods nutritional value, and their performance in rearing aquatic organisms. Fish meal replacement with meals sourced from gastropods is closely analysed in this paper. Synthesized information from this review will benefit future research on this subject.
