The feed consumption of goats was only reduced after considerable Se depletion. The conversion of Se-depleted animals to an Se-rich ration increased feed consumption within one day. An intrauterine Se deficiency (less than 38 micrograms Se/kg DM of the ration) did not induce intrauterine growth depression in kids. Se depletion led to a highly significant postnatal growth depression which increased with advancing Se depletion both during the lactation period and after weaning.

Aflatoxin is a mycotoxin produced by fungi of the genus Aspergillus that is present in various foods. Probiotics are well-established products in aquaculture, and due to their effective contribution to the intestine, they can be used as an aflatoxin adsorbent. This study evaluated the effects of aflatoxin B1 (AFB1) on enzymatic activity and intestinal function in Piaractus mesopotamicus (pacu) fingerlings fed diets containing a probiotic-based adsorbent (PBA).

Water is an essential resource for dairy cows, and its consumption is closely linked to feed intake. Social competition can lead to changes in drinking behavior, especially for subordinate cows. We studied how changes in stocking density at the feeder (1 or 2 cows per feeder), and drinker (6 or 12 cows per drinker) and a temporal feed restriction (14- or 24-h access) affects drinking in 4 groups of 6 cows each, following a Latin square design.

During the harvest of Ilex paraguariensis, approximately 2-5 tons per hectare of thick stems are left on the soil surface. The outer portion of these stems, referred to as the coproduct, constitutes 30% of the total residue mass. Although this coproduct has been partially characterized in terms of its phytochemical profile, its technological applications remain unexplored.

Fine grinding using a stirred ball mill can enhance ore liberation but incurs high energy consumption, which can be minimized by optimizing operating conditions. This study explores the impact of key operational parameters-grinding time, stirrer tip speed, solid concentration, and feed size-on grinding efficiency, evaluated using specific energy inputs, in stirred milling of Egyptian copper ore. The particle size distribution (PSD) of ground products was simulated using the Gates-Gaudin-Schuhmann model (GGS) and the Rosin-Rammler-Benne (RRB) function.

The domesticated silkworm, Bombyx mori, is crucial for global silk production, which is a significant economic activity supporting millions of livelihoods worldwide. Beyond traditional silk production, the growing demand for insect larvae in cosmetics, biomedical products, and animal feed underscores the need to enhance B. mori productivity.
