“…Apparent absorption and retention of zinc in lambs which obtained organic forms were higher in comparison to animals received this trace element as oxide. On the contrary, Spears (1989) in experiments on fattening lambs indicated that apparent absorption of zinc from zinc-methionine and oxide was similar. However, the zinc excretion in urine was lower for lambs which received zinc-methionine, what caused the increase of zinc retention.…”

On the other hand, Spears (1989) had not indicated the influence of zinc form (Zn-methionine vs. zinc oxide) in lambs on its level in blood serum.

The aim of the presented study was an estimation of the zinc bioavailability derived from amino acid complexes with methionine, lysine and glycine in growing lambs. 48 lambs, Polish Merino × Romanowski × Charolaise crossbreed, at age about 10 weeks and average body weight of 20 kg were randomly divided into 4 experimental groups. Animals were kept collectively and fed with concentrate and hay in amount: 0.7-1.2 and 0.3-0.5 kg/day/head, respectively. After rearing period 6 rams from each group with average body weight of about 30 kg were divided into digestibility-balance experiments. At the end of the experiment the blood samples were taken, then from each group 8 lambs were chosen, killed and during dissection tissue samples were taken (liver, pancreas, kidney and rib bone). In tissue samples as well as in fodders and excrements the content of zinc was determined. Obtained data in digestibility experiments allowed on calculation of apparent absorption and retention of zinc and the level of Zn determined in tissues' samples were used to the estimation of bioavailability of zinc from different ones applied in experiment sources.Apparent absorption and retention of zinc were higher (P≤0.01) in lambs receiving in mixtures amino acid complexes of zinc than in animals from the control group. The higher content of zinc in soft and hard tissues of lambs which received organic forms of zinc might indicate better assimilation and bioavailability of zinc from these forms than from oxide. Among tested organic forms of zinc, the zinc-lysine complex was characterized as having the most advantageous property.

“…Trace minerals are generally supplemented in the animal diet as inorganic salts. However, in recent years, chelated or organic minerals are being used as the bioavailability of these minerals is more than their inorganic counterparts (Spears, 1989). Lambs supplemented with zinc proteinate had higher Zn retention than lambs given a similar concentration of Zn from zinc oxide, an inorganic source (Lardy et al, 1992).…”

The effect of zinc supplementation from inorganic and organic sources on some physiological and biochemical profi le was investigated in 15 male crossbred calves (age 14-15 months, liveweight 226.0 ± 9.06 kg) randomly divided into three groups of fi ve animals in each. Animals in group I (control) were fed a basal diet comprised of wheat straw and concentrate mixture (33 mg Zn kg -1 diet) with out any supplemental Zn, while those in group 2 and group 3 were given basal diet supplemented with 35 mg Zn kg -1 feed from zinc sulphate and zinc propionate, respectively. All the animals were fed individually on these dietary treatments for a period of 180 days. Body weights of all the calves were recorded fortnightly. Blood samples were collected from all the animals at 0 day and subsequently at an interval of 30 days to estimate certain serum minerals, enzymes, vitamins and hormones. There was no signifi cant difference in the body weight gain among different groups. Zinc intake in groups 2 and 3 was signifi cantly (P<0.001) higher as compared to group 1, but serum zinc and copper concentration did not differ among the groups. Mean activity of alkaline phosphatase, glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and super oxide dismutase was also similar in control and Zn supplemented groups. Mean concentrations of different serum vitamins (retinol, ß-carotene and α-tocopherol) and hormones (triiodothyronine, thyroxin, insulin and testosterone) were not affected by zinc supplementation from inorganic and organic sources in crossbred calves.

“…In four consecutive studies conducted by [30], Zn was better retained when added as Zn methionine than ZnO in lambs and heifers. However, the observed improvement was not due to higher absorption but to a lower urinary Zn excretion in animals receiving Zn methionine, and only minor changes in blood parameters were noticed.…”

Trace minerals are dietary elements required by the body in minute amounts, ranging from 0.10 to 50.0 mg/kg dry matter in beef cattle diets [1]. These trace minerals are all necessary for the biochemical processes of the body that support proper growth and maintenance. For example, Cu is necessary for the function of superoxide dismutase and its removal of toxic byproducts from metabolic pathways [2]. The removal of these toxic byproducts allows for metabolism to proceed efficiently, uninhibited by damaging oxygen free radicals. Zinc, an important trace mineral for enzyme function, aides in the regulation of nucleic acid production, carbohydrate metabolism, and protein synthesis, thus providing a stable framework for development [3]. The immune system is part of the host's defense against destructive forces from outside the body, such as bacteria, viruses, and parasites, or from within, such as malignant cells or those that produce autoantibodies [4]. This system is composed of two branches: the innate or non-specific immune system, and the adaptive or specific immune system [5]. In this review paper, an attempt has been made to review effects of mineral supplements in Rumen Metabolism, effects on Immune Function in different species of animals.
