The delicate balance of trace mineral supplementation is critical for optimizing rumen function and overall ruminant health. This study evaluated the solubility of an advanced chelate technology-based supplement and assessed its impact on rumen degradability and apparent total tract digestibility (ATTD) when replacing inorganic sources. The solubility of the advanced trace minerals supplement (ACTM) was assessed at pH 5 and pH 2.

The present study aimed to evaluate the effect of thymol on growth performance and apparent total tract digestibility of nutrients in severely feed-restricted lambs. Twenty-one male Baluchi lambs were randomly blocked by live weight into three groups: control without feed restriction (CON), feed restricted (FR), and feed restricted plus thymol (FR + T). The lambs underwent a four-week feed restriction period followed by four weeks of realimentation.

Advanced chelate compounds technology is a novel technology that introduces a new generation of chelates to deliver trace elements better by polymerization of organic acids. In the present study, the over-supplementation effect of Bonzaplex7 supplement, which is designed based on the aforementioned technology, was evaluated on milk yield of dairy Holstein cattle through two experiments. In the first experiment (exp.

Poultry well-being and economic burden due to heat stress (HS) are of great importance to the poultry industry. Efficient design and effective evaluation of any strategies to alleviate the adverse effects of HS on poultry production require an accurate measurement of stress. However, current methods for monitoring stress in poultry are less than ideal, as they are invasive or subjective, and therefore variable.

Article Synopsis
  • Heat stress significantly hampers growth and leads to economic losses in the poultry industry, creating a need for effective mitigation strategies.
  • The study explored the effects of Noni, a tropical medicinal plant, on broiler chickens' feeding behaviors and stress-related gene expression under acute heat stress conditions.
  • Results showed that while Noni did not increase feed intake, it helped reduce core body temperature and modulated gene expression linked to stress response, indicating potential benefits for managing heat stress in poultry.

Article Synopsis
  • - Heat stress (HS) affects fat metabolism in broilers by decreasing feed intake and body weight while altering the expression of key proteins involved in fat synthesis and breakdown in the liver.
  • - A study examined the impact of both acute (2-hour) and chronic (3-week) HS on genes related to fat metabolism in broilers fed a control diet versus one supplemented with 0.2% dried Noni plant.
  • - Results showed that Noni supplementation influenced the expression of lipogenic proteins differently across HS exposure times, highlighting its potential to modulate fat metabolism, although it did not significantly affect growth performance.

The protein-sparing effect of condensed tannins (CT) was investigated in growing lambs fed a low- or high-protein diet during a 50-day period. Isocaloric diets containing 106 g crude protein/kg dry matter (DM) (low protein; LP) or 138 g crude protein/kg DM (high protein; HP) were formulated using 70 % concentrate, 15 % corn silage, and 15 % dried licorice leaves, providing CT (4.1 g/kg DM).
