“…Table 3 shows that betaine supplementation generated lower rectal temperature and respiration rate than non-supplemented birds (p<0.01). Exposure to heat stress leads to stressful behavioral responses and severe physiological dysfunctions, such as panting and an elevated respiratory rate in poultry [17]. The results of this study show that the osmoprotective function of betaine can maintain the rectal temperature and respiration rate.…”

The high environmental temperature in the tropics adversely affects the physiology and performance of poultry. Betaine is an organic osmolyte that assists the birds in counteracting the deleterious effects of heat stress. This study observed the physiological parameters of laying quail raised in tropical environments and receiving betaine supplementation in the diet. A total of 224 21-day-old quails were distributed to two treatments with seven replicates of 16 birds. The treatments were the basal diet (Control) and the basal diet supplemented with 1.5 g/kg betaine (Betaine). The rectal temperature, respiration rate, and tonic immobility were measured in the morning (07.00h), afternoon (13.00h), and evening (19.00h). The temperature humidity index in the morning, afternoon, and evening were 24.7, 29.4, and 27.6, respectively, suggesting the birds expressing heat stress. Administering betaine in the diet reduces the rectal temperature, respiration rate, and tonic immobility in all measurement times (P<0.01), indicating that betaine maintains the physiological condition in quail. In conclusion, betaine functions as an organic osmolyte to assist the birds in coping with heat stress

This review focuses on the osmoregulatory function of betaine and its effect in terms of alleviating heat stress in poultry. Poultry appear to be particularly sensitive to temperature‐associated environmental challenges, especially heat stress. High ambient temperatures are deleterious to productive performance in poultry, including broilers, laying hens, quails and turkeys, resulting in considerable economic losses. Heat stress impairs overall poultry production by decreasing feed intake and negatively affecting intestinal development, leading to reduced nutrient digestibility. Apart from inducing a high mortality rate, heat stress is known to depress growth rate and reduce meat yield in broilers. In layers, lower feed intake impairs ovarian function, leading to decreased feed efficiency, egg production and egg quality. In addition, reduced immune functions, such as thyroid activity and antibody production, are evident in poultry exposed to heat stress. Heat stress increases the production of oxidants, causing oxidative stress and lipid peroxidation of cell membranes. Poultry respond physiologically and behaviourally when encountering the negative effects of heat stress, attempting to return the body to homeostasis. This requires energy at the expense of weight gain or egg production. Due to its zwitterionic structure, betaine has osmoprotective properties that aid in protecting intestinal cell proteins and enzymes from environmental stress, including high ambient temperature, thereby counteracting performance losses. Betaine also exerts an osmoregulatory role in cells, regulating water balance, and this results in more stable tissue metabolism. Inclusion of betaine in the diet may be beneficial for alleviating physical reactions to heat stress, as indicated by increases in nutrient digestibility. In broilers, betaine supplementation increases weight gain and breast muscle yield, while improving feed conversion. In layers, betaine supplementation improves egg production, egg quality traits and immune indices. In conclusion, due to its osmoregulatory functions, betaine plays an important role in alleviating heat stress in poultry.

Three different diets were formulated with three levels of metabolizable energy (ME) (optimum; 2900, restricted; 2800 and low; 2700 kcal ME/kg diet) without or with (0 and 0.15%) betaine supplementation in 2 × 3 factorial design to evaluate the effect of six experimental diets on performance, proteins and lipids profiles, bioenergetics, peroxidation and meat quality of Japanese quail. Therefore, 360 quails allocated into six groups in a 23-day experiment. Dietary betaine and ME levels did not affect the performance, meat energy indices (ATP and AMP) and malondialdehyde (MDA) levels of Japanese quail meat. Dietary betaine and/or ME levels induced significant changes in serum triacylglycerol (TAG), total cholesterols (TC), low-density lipoprotein cholesterol (LDL-c), very low-density lipoprotein cholesterol (VLDL-c), meat total lipids and cholesterol of Japanese quail. Optimum and restricted ME levels reduced total volatile basic nitrogen (TVBN) whereas dietary betaine increased ecosapentaenoic (EPA), docosahexaenoic acids (DHA) and glutamine concentrations in breast meat of Japanese quail. Dietary betaine and low energy diet improved cooking loss, thawing loss (ThL) and water holding capacity (WHC) in breast meat of Japanese quail. Conclusively, dietary betaine improved meat quality of Japanese quail fed diets containing either restricted or low ME by enrichments the meat with omega-3 fatty acids and reduction of lipids levels.
