Article Synopsis
  • The study evaluated the use of Zn hydroxy chloride (ZnOHCl) as a potential replacement for Zn sulfate (ZnSO) in the diet of pre-ruminant crossbred calves to assess its effects on health and nutritional status.
  • Twenty-four male calves were divided into four groups, receiving different levels and sources of zinc supplementation over a 90-day period, while all were fed according to established nutrient standards for growth.
  • Results showed no significant health status changes or hematological differences across the groups, but zinc supplementation improved certain biochemical markers and enhanced total antioxidant capacity and immune responses, with no notable differences among the types of zinc administered.

  • - The study investigates the effects of varying levels of nickel (Ni) supplementation on mineral balance and health in crossbred dairy calves, recognizing nickel's importance as a trace mineral, although its mechanisms are not yet clear.
  • - Twenty-four male calves were divided into four groups receiving different amounts of nickel (0, 5, 7.5, and 10 ppm) and were monitored for growth, mineral absorption, and health parameters over a 150-day period.
  • - Results showed that while nickel supplementation did not affect overall intake, weight gain, or nutrient digestibility, it did enhance the absorption and balance of essential minerals like iron, copper, and zinc in the calves' plasma.

Zinc (Zn), an important microelement in ruminant diet, plays a critical role in various enzymes, hormones and functional proteins involved in nutrient metabolism. The present study was conducted to assess the effect of zinc hydroxychloride (Zn(OH)Cl·HO [ZnOHCl] and zinc sulphate (ZnSO) on nutrient utilisation, mineral metabolism and biomarkers pertaining to growth performance in pre-ruminant crossbred calves. Twenty-four crossbred calves [body weight (BW); 31.

  • In a study with 12 Sahiwal bulls, groups were given different levels of iodine (0.250, 0.375, and 0.500 ppm) for 60 days to assess its effects on their health, hormones, and sperm quality.
  • Results showed that higher iodine intake improved testosterone and thyroxine levels, enhanced sperm viability and motility, reduced lipid peroxidation, and boosted sexual behavior, indicating that 0.500 ppm iodine supplementation is beneficial for these bulls.

  • Boron (B) is recognized as a beneficial micronutrient for certain farm animals, but its effects on energy balance and production performance during critical periods like transition need further exploration.
  • A study involving thirty pregnant Murrah buffaloes examined the impact of B supplementation at two levels (200 ppm and 400 ppm) on their nutrient utilization and performance before and after calving.
  • Results showed that B supplementation reduced levels of plasma nonesterified fatty acids (NEFA) and improved the absorption of certain minerals like magnesium and zinc, indicating its potential role in energy and mineral metabolism; however, more research is needed to fully understand these effects.

  • Boron (B) is believed to be important for bone growth and helps regulate minerals like calcium, phosphorus, and magnesium, which work together with vitamin D.
  • The study aimed to investigate the effects of different levels of boric acid (BA) supplementation on the bone health of growing crossbred calves over two phases.
  • Results indicated that higher doses of BA (200 and 400 ppm) positively influenced various bone health markers, such as plasma levels of alkaline phosphatase and osteocalcin, but did not change the levels of certain other markers like TRAP.

  • Calcium homeostasis and the immune-endocrine system undergo significant changes in dairy animals around the time of giving birth, affecting their health and productivity.
  • The study examined the effects of dietary boron supplementation on calcium metabolism, bone health, hormone levels, and antioxidants in pregnant Murrah buffaloes as they approached giving birth.
  • Results showed that boron supplementation increased essential mineral and vitamin D levels, reduced certain hormone levels, and improved antioxidant activity in buffaloes during the postpartum period.

  • * Studies indicate that REE supplementation can improve various performance metrics in farm animals, such as weight gain and milk production, though results are inconsistent and the mechanisms behind these benefits remain unclear.
  • * REE may benefit gut health and animal immunity through local action in the gastrointestinal tract, showing promise as a safe alternative feed additive, but further research is needed to clarify results and enhance effectiveness before wide adoption can occur.

Vanadium (V) has not been elucidated as an essential mineral in ruminants, though in lower organisms and rat model, its role is well known as insulin-a mimetic agent for catalyzing enzymatic activities. The objective of this study was to determine the effect of V supplementation on production performance, milk composition, and mineral profile in lactating goats. Twenty-four crossbred goats (body weight 34.

  • The study evaluated how inorganic vanadium (V) affects antioxidant enzymes, immune response, and blood biochemical traits in young crossbred calves over 150 days of feeding.
  • Twenty-four male Karan Fries calves were divided into four groups: a control group without V and groups receiving varying doses of V (3, 6, and 9 mg/kg diet).
  • Results showed that while V supplementation did not significantly impact daily growth or feed intake, the highest V dose reduced plasma cholesterol and increased glutathione peroxidase activity and immunoglobulin G levels.

  • Ultra-trace elements, like vanadium (V), play critical roles in biological processes such as glucose and lipid metabolism and may help alleviate stress in diabetes when used in low doses.
  • Vanadium competes with iron for transport in the body and inhibits certain enzymes that can help promote glucose uptake in cells, particularly with insulin present.
  • While most research has been conducted on lab animals, there is emerging evidence supporting vanadium's potential benefits and risks as a therapeutic agent for various diseases in humans and larger animals.
