The present study was conducted at the Poultry Research Center, Faculty of Agriculture; Sebha University, Libya. The feeding trial lasted 42 days in total. A local hatchery provided 240 unsexed one-day-old broiler chicks (Ross 308). The birds were randomly distributed into four groups, and each group was then divided into four replicates, with 15 birds in each group. The objective of the current study was to examine the impact of ginger powder as a natural feed supplement on broiler chickens' growth performance, hematological parameters, and serum lipids. Four dietary treatments were formulated and supplemented with ginger powder at levels 0%, 0.2%, 0.4% and 0.6%. The findings exhibited substantial differences in body weight and weight gain across the experimental groups. Birds fed ginger-enriched diets had higher feed conversion and lower feed intake than control birds (P<0.05). Birds fed a 0.6% ginger powder diet compared to the control group had considerably superior productive performance (P<0.05), while feed consumption was lowered. Dietary ginger powder supplementation improved hematological parameters; white blood cells, lymphocytes, heterophils, and the lymphocyte to heterophil ratio were improved with dietary ginger powder supplementation (P<0.05). Additionally, as compared to the control group, ginger powder groups significantly (P<0.05) lowered serum triglycerides, total cholesterol, and very low-density lipoprotein. While supplementation of dietary ginger powder significantly increased (P<0.05), the levels of high-density lipoprotein against the control group. In conclusion, ginger supplementation had a positive …

A total of 240 1-day-old broiler chicks (Cobb500) were purchased from a local hatchery and randomly distributed into four dietary treatments. Each treatment comprised 5 replicates with 12 chicks each. Garlic powder (Allium sativum) was supplemented as follows: 0.0%, 0.1%, 0.2%, and 0.3%. The diets were formulated to be approximately isocaloric and cover all nutrient requirements for broilers throughout two stages of growth periods: starter diets (1–21 days) and finisher diets (22–42 days). At the end of the experiment, one bird was chosen from each replicate to measure the carcass characteristics and blood was collected.

The purpose of this study was to see how non-antibiotic growth boosters such as Probiotic, Prebiotic, Synbiotic, and medicinal herbs (Mixture of Origanum majorana, Foeniculum vulgare, and Carum carvi in a 1:1:1 ratio) affected carcass yield, immune response, blood hematological, and biochemical parameters in broilers fed test diets with two dietary protein levels (normal and low). The research was conducted at Alexandria University, Poultry Research Center, Faculty of Agriculture. The trial lasted 42 days in total. A total of 500 one-day-old Cobb broiler chicks with similar average live body weight were assigned to one of ten treatment groups. Each treatment has five replicates with ten chicks each. Ten experimental diets were developed to be nearly is caloric and to provide all nutrients required for broiler growth throughout two stages of development: starter diets (1 - 21 days) and grower diets (22 - 42 days). Ten experimental diets were made up of five feed-additive programs and two amounts of crude protein (recommended or low, 85 percent of recommended) (control, probiotic, prebiotic, synbiotic and medicinal plants). Among the additives, synbiotic had a positive effect on the WBCs, RBCs, in general, especially the Fabricius bursa Under the conditions of the current study, synbiotic had a significant impact on hematological parameters, carcass yield, and immunological organs of broiler. Furthermore, more research is required to confirm the existing findings.

The aim of this study was to investigate the response of broilers fed on test diets containing non-antibiotic growth promoters; Probiotic (BioPlus 2B), Prebiotic (TechnoMos), Synbiotic, and medicinal herbs (Mixture of Origanum majorana, Foeniculum vulgare, and Carum carvi in ratio 1: 1: 1), each within two dietary protein levels (normal and low), on these broiler performance. The study was carried out at the Poultry Research Center, Faculty of Agriculture; Alexandria University, Egypt. The experimental period lasted for 42 days. A total number of 500 days from Cobb broiler chicks, with similar average live body weight, were randomly distributed into 10 treatments. Each treatment comprised of 5 replicates of 10 chicks each. Ten experimental diets were formulated to be approximately isocaloric and cover all nutrients required for broiler throughout two stages of growth periods, starter diets (1-21) and finisher diets (22-42) days of age. Ten experimental diets were consisting of two levels of crude protein (recommended or low (85% of recommended)) and five feed-additive programmes (control, probiotic, prebiotic, synbiotic and medicinal plants). In general, feeding broiler lower crude protein levels (-10% of NRC) resulted in poorer growth performance, which was partially compensated with the non-antibiotic additives. Among the additives, synbiotic had positively significant effects on FCR, BW.
