“…The lack of differences in the final body weight but higher carcass yield in EHS-fed broilers in the present study agreed with a recent study in which a lack of effect on the final body weight, but higher breast weight and yield were observed in broilers added with potassium humate [35]. Our results indicate that the FI and the intake of nutrients (see Table 5 below), the WG, and FCR were similar among treatments, but it might be that these nutrients were used differently inside the body.…”

“…In broilers, fed diets containing HS, increased antibody titers against the avian influenza virus [61] and Newcastle virus [47,62] has been reported. It has been suggested that the improved immune response in broilers fed HS-added diets may be due to the greater growth of immune organs such as the thymus and bursa of Fabricius [35]. It may be possible that through improvements of the immune response, the addition of EHS in the present study reduced the oocyst excretion.…”

Humic substances (HS) from different sources have been evaluated to replace or reduce the use of growth promoter antibiotics (GPA) in the feeds of broiler chickens. The objective was to evaluate the growth performance, tibia measurements, nutrient balance, meat quality, and microbiological status of broiler fed with an HS extract (EHS) under ad libitum (ADLIB) or feed restriction (REST). Individually caged broilers (n = 180, 14–35 day of age) were assigned to a factorial arrangement of three dietary treatments: (1) positive control with bacitracin methylene disalicylate (BMD) and salinomycin; (2) negative control without BMD nor salinomycin, and (3) same as negative control with 0.25% EHS, and two feeding regimens 1) ADLIB or REST for 24 h on d 1, 7, and 14. Results were subjected to ANOVA. Positive control and EHS-fed broilers showed higher carcass yield (p < 0.05) and lower oocyst excretion (p < 0.01) compared to negative control birds. Lactic acid bacteria (LAB) and Clostridium perfringens (C. perfringens) were higher in negative control and EHS-broilers compared to positive control (p < 0.01). In conclusion, higher carcass yield, lower C. perfringens and oocyst excretion were found in positive control and higher carcass yield, higher LAB and lower oocyst excretion were found in EHS-fed broilers. Broilers subjected to REST had reduced growth performance and meat quality. In conclusion, EHS could be used to increase the carcass yield and beneficial LAB in broilers.

“…In fact, the desirable blood metabolites levels realized in the current study indicates the potential of C. lanatus essential oil with phytogenic compounds in improving the general health status of layers. In other studies, compounds of similar nature were observed to reduce the hematological disorders associated with aflatoxins and mycotoxins in feeds ( Tehrani et al., 2012 , Disetlhe et al., 2018 ).…”

“…In the current study, it was observed that dietary inclusion of C. lanatus seed oil significantly improved TDPE, TW, TAW, and TBS. In particular, the observed increase in bone breaking force with inclusion of C. lanatus essential oil could be reflective of the ability of the oil to improve the bone health and general welfare of the birds which are supposed to stand for long periods of their productive life ( Świątkiewicz et al., 2014 , Disetlhe et al., 2018 , Kolakshyapati et al., 2019 ). To our knowledge, very few attempt have been made to assess the effects of essential oils on bone development in layer birds.…”

The study evaluated the effects of Citrullus lanatus essential oils inclusion in diet on egg production, egg quality, and physiological parameters in layer hens. A total of 72 White Leghorn point-of-lay hens at 18 wk were used for the study. The hens were randomly allocated to following 3 dietary treatments: 1) commercial layer diet (control), 2) commercial diet + 1 g C. lanatus essential oil/kg feed ( 1gCL ), and 3) commercial diet + 2 g C. lanatus essential oil/kg feed ( 2gCL ). Each treatment was replicated 8 times arranged in completely randomized design. From the results, an increase in total weight gain, average daily feed intake, and average daily gain was observed with inclusion of the C. lanatus essential oil. In addition, the inclusion of C. lanatus in diet improved the egg mass and feed conversion ratio ( FCR ). Hens fed C. lanatus –containing diets had higher egg mass (1gCL, 53.35 g ± 0.71; 2gCL, 53.99 ± 0.71 g) compared with the control (52.90 ± 0.71). The C. lanatus containing diets also had lower FCR than the control (1gCL [2.18 ± 0.22] and 2gCL [2.16 ± 0.22] vs. control [2.20 ± 0.71]). With regards to egg quality parameters, inclusion of C. lanatus oil appeared to reduce shell weight and shell ratio, while increasing albumen height and Haugh unit. Diets containing C. lanatus had significantly higher amounts of stearic acid, and linoleic acid was highest ( P < 0.05) in the 2gCL fed hens. Birds fed the 2gCL diet (15.29 ± 0.60) had the highest total polyunsaturated fatty acids, total n-6 fatty acids (14.81 ± 0.59) and also had the highest n-6/n-3 ratio. An increase hematological values was observed with inclusion of C. lanatus essential oils in diets. Moreover, tibia bone parameters were also significantly improved with inclusion of C. lanatus essential oils in diets. It can be concluded that C. lanatus essential oil positively affected egg production, and quality and health of layer hens can be used successfully as a natural feed additive.

“…The hepatoprotective ability of humic acids was observed in experiments on broilers using rapeseed meal containing an increased amount of secondary plant metabolites that could cause liver damage. The low AST level in the blood of chickens fed with humic acid indicates its hepatoprotective ability [20]. Use of liquid Reasil®HumicVet in feeding broiler chickens of the Cobb 500 cross at the age of 9 to 34 days and laying hens of the High-Line cross during the period of intensive egg laying in an amount of 0.06 ml per 1 kg of live weight contributed to an increase in productivity and the safety of poultry, an improvement in the morphological state of the liver and a decrease in AST and ALT indicators.…”

Humic Substance [Working Title]

The purpose of this chapter was to study the influence of humic substances on the formation of the safety and quality of poultry meat. The high abilities of the natural and organic complex of humic acids “Reasil®HumicHealth” (produced in Russia, Saratov) to sorb and desorb five mycotoxins of compound feed (aflatoxin B1, ochratoxin, toxin T-2, zearalenone and fuminisin B1) were experimentally established. The hepatoprotective ability of humic acids was observed in experiments on broilers using rapeseed meal containing an increased amount of secondary plant metabolites that could cause liver damage. It was found out that the inclusion of humic acids in the amount of 1 and 1.5 g per 1 kg of feed to the main diet of broiler chickens has a more stable positive effect, both in terms of slaughter indicators (yield of semieviscerated carcasses and carcasses of complete evisceration), and in the production of the most valuable natural semi-finished products (breast, chicken legs) due to the intensive growth of muscle tissue. A clear improvement in the morpho-biochemical and immunological parameters of blood and micromorphometric characteristics of the organs of the immune system of poultry was noted with the use of different concentrations of humic acid salts. The use of the additive at the rate of 1 and 1.5 g per 1 kg of feed does not negatively affect the sensory indicators of finished culinary products.
