“…In this sense, chromium (Cr) supplementation, as Cr propionate or Cr methionine, has shown increases in the percentage of carcass muscle and decreased carcass fat in pigs and poultries (1). In ruminants, Cr requirements have not been clearly established (2) and there is limited information available on the effects of Cr on carcass characteristics in feedlot cattle (3) and in feedlot lambs (4). In a recent study (5), linear decreases (P = 0.02) in kidney-pelvicheart fat and fat thickness were observed in finishing steers supplemented with chelated Cr (as Cr-enriched yeast) at daily levels of 0, 5, 10, or 15 mg/head.…”

One of the main goals of the feedlot industry is to increase efficiency in the final stages of fattening. Therefore, the use of modulators of growth (hormones and beta-agonist agents) is widespread. The concern about the potential impact of the use of these growth promoters has furthered interest in the search for safe alternatives of modulating agents of growth in recent years. In this regards, the use of chelated minerals has shown interesting advantages in nonruminant species. In this sense, chromium (Cr) supplementation, as Cr propionate or Cr methionine, has shown increases in the percentage of carcass muscle and decreased carcass fat in pigs and poultries (1). In ruminants, Cr requirements have not been clearly established (2) and there is limited information available on the effects of Cr on carcass characteristics in feedlot cattle (3) and in feedlot lambs (4). In a recent study (5), linear decreases (P = 0.02) in kidney-pelvicheart fat and fat thickness were observed in finishing steers supplemented with chelated Cr (as Cr-enriched yeast) at daily levels of 0, 5, 10, or 15 mg/head. According to the above study, the maximum response levels were observed when cattle were fed with levels three-fold what is currently recommended. There is limited information regarding the effects of high levels of Cr supplementation on carcass characteristics and chemical composition of muscle of finished lambs. Therefore, the aim of this trial was to evaluate the effects of feeding different levels of chromium methionine on the carcass characteristics and chemical composition of the longissimus muscle (LM) in hairy lambs fed a high-energy diet. Twenty-four Pelibuey × Dorper (initial weight at start of experiment: 24.9 ± 0.2 kg) were assigned (six lambs/treatment) in indoor facilities in collective pens of 16 m 2 with automatic waterers and 1.2 m fence-line feed bunks. Lambs were fed ad libitum with a finishing diet formulated as follows (dry matter basis): 61.2% ground maize, 14.5% soybean meal, 12.6% Sudan grass hay, 7.7% molasses cane, 2.5% mineral premix, and 1.5% zeolite. The calculated composition of the basal diet dry matter basis (6) was as follows: crude protein, 17 g/kg; metabolizable energy, 12.09 MJ/kg; ether extract, 29 g/kg; calcium, 98 g/kg; and phosphorus, 36 g/kg. Lambs were adapted to the basal diet and facilities 14 day Abstract: Twenty-four male lambs (24.93 ± 0.93 kg) were used in order to evaluate the effects of chromium methionine (Cr) supplementation in high-energy finishing diets on the carcass characteristics and chemical composition of the longissimus muscle (LM). Treatments were 0.00, 0.60, 1.20, and 1.80 mg Cr/lamb daily. The experiment lasted 56 days. There were no effects of treatments on dry matter intake, feed to gain ratio, and final weight, which averaged 35.24 ± 1.01 kg. Supplemental Cr linearly decreased fat thickness enough to improve the estimated yield grade from 1.82 to 1.42 with no effect on the other carcass traits measured. Fat concentration in the LM decreased linearly as the lev...

“…103-109). In practice, the subclinical deficiencies of trace elements, along with hypovitaminosis and the hypervitaminosis, occur more frequently than clinical deficiencies and are often confused with a low consumption of energy or protein (Pallauf and Muller 2006). An inadequate intake of vitamins and trace elements can depress the immune system and determine the onset of disease from low-income, with serious damage to livestock production (Woodfield and Easton 2004).…”

A study was carried out to evaluate the influence of vitamin and trace mineral supplementation on milk production and composition in grazing dairy ewes during the dry season. Ewes (n = 50) were assigned at weaning to blocks and treatments. Ewes were daily conducted (8 h/day) on a pasture based on Italian ryegrass (Lolium multiflorum). At fold, ewes received a basal diet composed by ad libitum oat hay and a definite amount of a pelleted concentrate. Dietary treatments included: (1) the control concentrate containing background of vitamin and trace mineral only, and (2) the experimental concentrate containing the premix supplement (10 g/kg of dry matter). Vitamin and trace mineral supplementation did not affect ewes' body weight. Milk, fat- and protein-corrected milk, fat percentage, and clotting properties were improved in ewes fed supplemented concentrate. There was a week × treatment interaction (P < 0.05) for yield of milk and corrected milk that was greatest at peak production in ewes fed the premix. Our findings indicate that in grazing dairy ewe, the dietary vitamin and trace mineral supplementation during dry season led to an increase of milk production and quality, with positive improvement in milk clotting aptitude.

“…Both I and Se play vital roles in metabolic and reproductive processes but their concentrations in food are very low (Pallauf & Muller ). Thus, it is necessary to supplement inorganic I and Se to animals to meet their nutritional requirements and to increase their levels in animal products such as milk, eggs and meat.…”

“…The nutrient requirements of animals are considered the main input influencing the performance of ruminant livestock. Selenium (Se) and iodine (I) are integral part of different proteins and enzymes involved in important metabolic and antioxidant processes (Pallauf & Muller ). Moreover, both Se and I are highly essential for the function of the thyroid gland (Underwood ).…”

This study assessed the effects of dietary selenium (Se), iodine (I) and a combination of both on growth performance, thyroid gland activity, carcass characteristics and the concentration of iodine and selenium in Longissimus lumborum (LL) muscle in goats. Twenty-four bucks were randomly assigned to four dietary treatments: control (CON), basal diet without supplementation, basal diet + 0.6 mg Se/kg dry matter (DM) (SS), 0.6 mg I/kg DM (IP), or combination of 0.6 mg/kg DM Se and 0.6 mg/kg DM I (SSIP) and fed for 100 days. Animals fed diet SSIP exhibited higher (P < 0.05) body weight and better feed conversion ratio (FCR) than those fed other diets. Dressing percentage of goats fed the supplemented diets was higher (P < 0.05) than that of the control. Carcasses from the IP group had higher (P < 0.05) total fat proportion than the SSIP group. The levels of both elements were significantly elevated (P < 0.05) in LL muscle in supplemented goats. Thyroid follicular epithelial cells of IP and SSIP animals were significantly higher than those of CON and SS groups. The study demonstrated that the combined Se and I dietary supplementation improves growth performance, carcass dressing percentage and increases the retention of Se and I in goat meat.
