“…Similar improvements in BWG were observed in birds with heat stress when graded levels of K (from 0.05 to 0.15%) were supplemented (Teeter and Smith, 1986). In the recent past, relatively high K (0.9-1.0%) resulted in better feed-efficacy (FCR), those levels being higher than recommended by NRC for birds kept in the condition of heat stress (Ribeiro et al, 2008). Heat stress is considered responsible for loss of plasma K, however, supplementing extra K in the diets does not exacerbate it further.…”

Electrolytes (sodium, potassium and chloride) are compounds that dissolve into positive and negative particles in solution. The relationship between these compounds, known as the 'dietary electrolyte balance' (DEB), is affected by either electrolyte or its supplemental salt source. The National Research Council recommended 0.20% sodium, chloride, and 0.30% potassium for starter phase and lower doses of sodium and chloride for the finisher phase of broilers. However, these requirements are increased under heat stress conditions, and birds perform better when increasing levels of these electrolytes are offered, maintaining a DEB of preferably 250 mEq/kg. Increased levels of these electrolytes, especially sodium, were found effective for growth but caused increased water consumption and ultimately higher litter moisture in summer. Potassium and chloride were found effective in the diets of heat-stressed broilers. Sodium bicarbonate and potassium chloride have been recognised as the best choice in salt selection for broiler diets, particularly under hot summer conditions. In conclusion, a combination of the electrolytes with higher levels of cations and lower level of anions is recommended. Furthermore, the requirements of these electrolytes should be explored, with reference to current poultry housing systems and modern genetics.

“…According to Ribeiro et al (2008a), under the heatstress conditions typical of Brazilian summers, higher Na levels (0.25% during the starter phase and 0.22% during the grower phase) improve feed conversion ratio. Those authors found that under the same hot conditions, better feed conversion and weight gain results were achieved when diets were formulated with HMTBA compared with DLM.…”

The objective of this study was to evaluate the influence of methionine sources (DL-methionine 99% powder (DLM) or methionine hydroxy analog liquid 88% (HMTBA)), arginine:lysine (Arg:Lys) ratio and sodium chloride (NaCl) content in the diet of broilers on their performance, carcass yield, serum biochemistry, duodenal mucosal morphology, and immune response. Birds were kept under high temperature conditions during the grower phase and were inoculated or not with an antigen. The use of HMTBA promoted better live performance and carcass yield than the use of DLM. Diets with 1.05 Arg:Lys ratio resulted in better live performance, higher carcass and breast meat yields, longer villi, shallower crypts, and stronger immune response when broilers were challenged than the 1.40 ratio. The dietary supplementation of 6.0 g NaCl/kg promoted better growth performance and carcass weight than 2.0 g NaCl/kg. There was no influence of the different methionine sources or NaCl concentrations on any evaluated intestinal morphology parameter or immune response, nor of any interactions between these sources of variation.
