  The essentiality of nutrients keeps on changing with the advancement in nutritional research and genetic gain. The genetic gain especially in poultry sector is very high which results in increase in nutrient requirement of both the essential and non-essential nutrients. For the rapid growth the requirement of essential nutrients reaches many folds which are in direct relation with the performance, but the requirement for non-essential nutrients is an indirect one. Most of the dispensable amino acids, vitamin C, carnitine, etc. which are being synthesized endogenously are now a days unable to meet the birds requirements that warrants the dietary supply. Another important nutrient is coenzyme Q10 (CoQ10) which endogenously synthesized is now gaining much attention as a supplement for fast growing broilers. The CoQ10 can be termed as multi-functionary as each and every cell in the body needs this but quantity is being high for very active organs like heart, lungs, liver, kidney, etc. They are essential for cellular oxidative phosphorylation and regenerative antioxidant. The supplementation of CoQ10 improved the feed efficiency with reducing the electron leaks from mitochondria and increases total antioxidant capacity. For this property, CoQ10 is widely used in human medicine especially persons suffering from cardiac, neurological disorder, hypercholesterolemic condition and also even in cancer. The CoQ10 in poultry draws first attention when it is found to reducing the ascites mortality in marketable broilers. Thereafter, the advantages of CoQ10 is started to exploit with much attention to ascites, feed efficiency, cholesterol lowering effect nutraceutical and nutrigenomic property both in poultry and swine industry.

  The three naked neck broiler genotypes (NaNa, Nana and nana) were investigated for the effect of temperature on juvenile body weights, shank length, immune competence and carcass characteristics. Weekly body weights were recorded from day old to six weeks (n = 417). The body weights were significantly higher in naked neck genotypes (NaNa and Nana) at 4th, 5th and 6th week of age. Birds with NaNa and Nana genotype recorded significantly (p≤0.05) higher weight gains during 4th (211.17 g) and 5th (207.96 g) week, respectively than nana genotype. The body weight gains were numerically higher at all ages either in NaNa or Nana genotypes without any significant difference. The shank length did not show any significant variation among the genotypes, which ranged from 78.54 mm in full feathered (nana) birds to 79.67 mm in heterozygous (Nana) population with an overall mean of 79.13 mm. Mean anti SRBC titre, anti NDV titre and response to PHA-P ranged from 3.55-5.6, 2.75-5.10 and 1.35-1.47 mm, respectively in different genetic groups. The dressing percentage was significantly higher in NaNa genotypes (71.96) than their normal (nana) siblings (69.66), which can be attributed to higher body weight and less losses due to lack of feathers in naked neck chicken. The liver, heart and gizzard weights are numerically higher in NaNa and Nana genotypes. The present study invariably concluded that Na gene in homozygous and heterozygous condition is more beneficial to exploit for better performance of Naked neck in tropical conditions.
