Effect of replacing inorganic with organic trace minerals on growth performance, carcass characteristics and chemical composition of broiler thigh meat

Abstract

Micro minerals (Trace minerals) are required for normal growth and development in broilers. The present study was undertaken to compare the effect of replacing inorganic with organic trace minerals on growth performance, carcass characteristics and chemical composition of broiler thigh meat. A corn soybean based diet supplemented with organic trace minerals (OTM) (x) and an inorganic trace mineral (ITM) (y) was prepared. Four hundred eighty birds were stratified by weight and randomly assigned to 6 dietary treatments with four replicates per treatment (20 birds/replicate pen). The treatments were A) Positive control group diet (x) supplemented for whole period (0-5 wk). B) Fed diet (x) during starter and grower phase (1-4 wk) and diet (y) was offered in finisher phase (5 wk). C) 1 st 3 weeks were fed diet (x) and last two weeks were given diet (y). D) First 2 weeks were fed diet (x) while, diet (Y) offered in the last three weeks. In the treatment (E), diet (x) offered during initial phase and nourished with diet (y) during grower and finisher phase while in treatment (F), complete diet (y). The result showed that organic trace mineral supplementation did not affect growth performance in the first and last week of trail but during 2 nd , 3 rd and 4 th weeks organic trace mineral supplementation showed better growth performance than that of inorganic trace mineral supplementation. Chicken fed with organic trace mineral supplemented diets had the better growth performance which differed from that of inorganic supplemented diet groups. Additionally, organic trace minerals supplementation did not affect dressing percentage and giblets weight but shank and keel lengths were improved. While, OTM supplementation did not alter dry matter, ash and moisture content in thigh meat; however, crude protein content was improved in thigh meat. Overall results demonstrated that the quality of broiler chicken meat in high organic trace mineral supplement increased relative to the low supplemented groups. It is concluded that addition of organic trace mineral to feed can improve the growth performance of broiler particularly during growing phase.

Measures and Gap Analysis on the Impact of Non-Indigenous Species on the Black Sea Ecosystem

“…The CP values of the meat samples of this experiment, which ranged from 21.18±0.66 to 22.1±0.6%. Furthermore, the AC and MC of the chicken breasts ranging from 1.47±0.25 to 1.73±0.21% and 73.43±0.95 to 74.47±1.14%, respectively, were similar to the study of Baloch et al (2017). The unaltered proximate contents of the treated chicken samples will add to the monetary value and consumer acceptability of the meat because of saving nutritional losses.…”

Supplementation of minerals and vitamins in broiler diets: effect on performance and bone quality

“…The more bioavailable minerals offer greater stability and benefit from biochemical protection against the different chemical reactions that can occur when added to the diet itself, expecting a better bird performance and higher absorption and utilization of these minerals when supplemented (16) , as well as less environmental impact (13,17) . However, regardless of the form in which the micromineral element is presented, its functions are maintained, so the form of presentation interferes only with bioavailability.…”

Effect of organic minerals and alpha-ketoglutarate in pheasant diet on performance, hatchability and the composition of eggs

“…Studies in poultry have shown that even low-level replacement of inorganic minerals with organic forms optimises the growth performance of broilers and laying performance of hens and reduces the pressure on the environment of the excreted minerals. In addition, the use of organic forms reduces antagonism between certain elements, such as Zn and Cu, and the mineral components from the proteinates have a higher retention rate and better bioavailability than inorganic salts (1,7,39,48).…”
