Special Issue Information

Dear Colleagues,

The “Special Issue on Rational Use of Feed to Promote Animal Healthy Feeding” explores the critical intersection of animal nutrition, health, and sustainability. Today, we face increasing challenges in global food production (climate change, resource scarcity, and an increasing population) while ensuring appropriate and responsible use of animal feed. The valorization of underutilized feed resources or by-products from the agri-food sector for animal farming is crucial in maintaining production efficiency and ensuring food security within the context of a circular bioeconomy. It can be used for improving the nutritional value of animal feed to strengthen the immune system, maintain a “healthy” digestive tract, and improve production performance through innovative methods. This Special Issue aims to focus on different aspects of farming practices, strategies, and solutions to reduce the environmental impact of livestock operations, improve feed conversion, and minimize waste. Contributors from various fields, including agriculture, nutrition, veterinary science, and environmental science, will collaborate to provide holistic insights into the complex issue of rational feed utilization. 

We cordially invite you to submit relevant articles to this Special Issue and hope that your valuable contributions will enrich the current level of knowledge.

The study aimed to assess the effects of including linseeds or hempseeds in the diets of late lactation Murciano-Granadina dairy goats on the nutritional quality of the milk and cheese fat, expressed by the fatty acids profile and the healthy lipid indices. Thirty-six goats were randomly distributed in 3 groups of 12 animals each, according to a 3 × 3 Latin square design, and fed three different diets: group CON (control, with sunflower meal, 11.5% DM basis); group LIN, where sunflower meal was replaced by linseed; and group HMP, where sunflower meal was replaced by hempseeds. The replacement had no effects on the milk yields and the milk protein content as no significant differences were detected among groups. The significant increase of the fat content in the case of the LIN and HMP groups was accompanied by significant decreases in saturated fatty acids concentration and very significant increases in monounsaturated fatty acids. The content of n3 and n6-PUFAs (polyunsaturated fatty acids) increased, mainly due to a 4.1 times higher proportion of alpha-linolenic acid (ALA; C 18:3n-3) in LIN diet milk and a 1.3 times higher proportion of linoleic acid (LA; C 18:2n6c) in HMP diet milk. The conjugated linoleic acid (CLA; isomer c9, t11) was 1.9 times higher for the LIN diet and 5.05 times higher for the HMP diet. Feeding either linseed or hempseeds contributed to the reduction of the atherogenic and thrombogenic indices, increased the hypocholesterolemic: hypercholesterolemic ratio as well as the proportion of other desired fatty acids in the milk fat. The improved nutritional quality of milk, which has potentially far-reaching human health benefits, is maintained in cheese through the increase of the n3 and n6-PUFAs, especially for the LIN diet where the n6/n3 ratio decreased significantly, compared with the CON diet (3.62 vs. 6.88). The CLA concentration was significantly higher (p < 0.001) for the HMP cheese compared with the CON diet (1.89% vs. 0.78%). These effects highlight the opportunity of obtaining dairy products with improved nutritional quality using local feed resources. Full article

Enhancing the quality of eggs by using natural food sources has become a very important topic in the last decade. The objective of this study was to determine the influence of natural (marigold and paprika extracts) pigments on the shelf life of eggs from laying hens. This research was carried out for a 6-week period on 168 Lohmann Brown laying hens (45 weeks age) divided into four groups (C, E1, E2 and E3) to assess the performances, external and internal egg quality parameters, egg yolk color, and antioxidant profile. The control group (C) was fed a standard diet (16.39% PB, 2750 kcal EM/kg compound feed) and the experimental diets were supplemented with 0.07% marigold extract (E1), 0.07% paprika extract (E2), and a mixture containing 0.07% of both extracts (E3). In summary, the study demonstrated that adding natural pigments from marigold and paprika extract with highly antioxidant lipid capacity into the diets of laying hens improved egg quality when eggs were stored at 28 days, under both storage temperature conditions (4 °C and 20 °C).

The objective of this study was to assess the impact that diets supplemented with grape seed cake rich in polyphenols had on lactating goats. The study investigated the quantity and quality of goat milk, the metabolic profile of blood, and the antioxidative status. The study involved 24 French Alpine dairy goats throughout their lactation period. The goats were, on average, 5 years old (±three months) and in the fourth lactation. The experiment lasted for 58 days. The control group (CON) had a diet without grape seed cake (GSC). The experimental groups were given a diet containing 5% and 10% GSC on a dry matter basis (GSC5 and GSC10, respectively). A slightly higher milk production, as well as protein and fat milk content, were found in GSC5 and GSC10, but the differences were not significant. Goat milk in the GSC10 group exhibited significantly higher activity of superoxide dismutase and glutathione reductase, as well as decreased concentrations of GUK and SCC. The feeding treatments did not affect significant differences in hematological and biochemical indicators, except for the BHB content, which can be associated with a higher energy value of feed containing GSC. There was an observed elevation in the activity of SOD within the blood of GSC5, and GSC10 was measured as well. The determined changes justify the supplementation of GSC rich in polyphenols to goat feed, especially in the amount of 10%, as it can reduce stress caused by lactation, which is known as a very stressful production period for animals.
