“…Interestingly, the current study demonstrated that dietary GA supplementation linearly reduces the contents of lysine in the breast and thigh muscles of laying hens. Although there is no information available to explain these results, a previous trial recorded that dietary humic acids decrease the level of lysine in the breast muscles of broiler chickens [ 40 ].…”

Guanidinoacetic acid (GA) is a natural precursor of creatine in the body and is usually used to improve the feed conversion and cellular energy metabolism of broiler chickens. The objective was to elucidate the effect of dietary supplementation of GA on carcass yield, muscle amino acid profile, and concentrations of brain neurotransmitters in laying hens. In total, 128 72-week-old ISA Brown laying hens were assigned to four equal groups (32 birds, eight replicates per group). The control group (T1) was fed a basal diet with no supplements, while the other experimental groups were fed a basal diet supplemented with 0.5 (T2), 1.0 (T3), and 1.5 (T4) g GA kg−1 diet. The T3 and T4 groups showed higher hen-day egg production and carcass yield compared to the control group (p = 0.016 and 0.039, respectively). The serum creatine level increased linearly with the increased level of dietary GA (p = 0.007). Among the essential amino acids of breast muscle, a GA-supplemented diet linearly increased the levels of leucine, isoleucine, phenylalanine, methionine, and threonine in the breast (p = 0.003, 0.047, 0.001, 0.001, and 0.015, respectively) and thigh (p = 0.026, 0.001, 0.020, 0.009, and 0.028, respectively) muscles. GA supplementation linearly reduced the level of brain serotonin compared to the control group (p = 0.010). Furthermore, supplementation of GA in the diet of laying hens linearly increased the level of brain dopamine (p = 0.011), but reduced the level of brain Gamma-aminobutyric acid (p = 0.027). Meanwhile, the concentration of brain nitric oxide did not differ between the experimental groups (p = 0.080). In conclusion, the dietary supplementation of GA may improve the carcass yield and levels of essential amino acids in the breast muscles, as well as the brain neurotransmitters in aged laying hens.

Abstract. Phytobiotics have a significant impact on the health of animals and increase productive qualities. At the same time, the question of studying the effect of individual herbal supplements on the physiological and productive indicators of poultry remains open. In this regard, the purpose of this study was to evaluate the effect of combinations of 4-hexylresorcinol with other herbal preparations on weight growth, as well as morphological and biochemical blood compositions of broiler chickens. Methods. The studies were conducted on 125 heads of 7-day-old broiler chickens (cross Arbor Icres, 5 groups, n = 25). Experimental scheme: control group – basic diet (BD); I experimental (BD + 4-hexylresorcinol; at a dosage of 0.5 mg /kg of live weight per day); II experimental (BD + 4-hexylresorcinol + gamma-octalactone at dosages of 0.4 mg/kg and 0.1 ml/kg of live weight per day); III experimental (BD + 4-hexylresorcin + 7-hydroxycoumarin in dosages of 0.1 mg/kg and 0.15 ml/kg of live weight per day); IV experimental (BD + 4-hexylresorcin+gamma-octalactone + 7-hydroxycoumarin in dosages of 0.05 mg/kg, 0.15 ml/kg and 0.01 mg/kg of live weight per day). The scientific novelty lies in the fact that for the first time the effect of the use of the herbal preparation 4-hexylresorcin in combination with other phytobiotics on the physiological parameters of broiler chickens has been studied. Results. It was found that chickens of the I, II and IV experimental groups at the age of 35 days were superior in live weight to individuals from the control group, with the maximum difference in relation to broiler chickens receiving a basic feeding diet. The introduction of the tested herbal preparations into the diet of the experimental bird had an ambiguous effect on the morphological and biochemical composition of the blood, which was expressed in the form of an increase in the level of individual elements with a significant decrease in others.
