Performance and egg qualities of old-laying hens fed with diets containing selected phytogenic feed additives

Abstract

Performance and egg qualities of old-laying hens fed with diets containing ginger, turmeric and garlic were evaluated in a twelve (12) week feeding trial. A total of 135 laying birds of Isa-Brown strain which were sixty-four (64) weeks old were used for the trial and arranged in a completely randomized design. Five diets were formulated for the trial: Diet 1 (control), Diet 2 (3% inclusion level of turmeric), Diet 3 (3% inclusion level of ginger), Diet 4 (turmeric and garlic at 2.25% and 0.75%, respectively) and Diet 5 (ginger and garlic at 2.25% and 0.75%, respectively). Proximate compositions of the Phytogenic Feed Additives (PFAs) were determined with the moisture content ranging between 5.03-7.50%; ash (3.26-6.11%); ether extract (7.39-14.58%); fibre (10.28-13.79%); protein (3.07-7.23%) and Nitrogen Free Extract (58.88-61.54%). The performance indices, though not significantly (P˃0.05) influenced by the test diets except for Hen Day Production (HDP) had the highest weight gained (0.16kg) recorded for birds fed on a diet containing ginger. The highest (62.92 and 62.04 %) HDP were observed in birds fed diets containing ginger and ginger + garlic; respectively. However, the lowest weight gained (0.04kg) was recorded in birds fed a diet containing turmeric + garlic; this diet also recorded the lowest % HDP and FCR with values of 57.50% and 2.37 respectively. The overall values for the qualities of eggs from laying hens fed the PFAs showed that only the Haugh Unit, yolk colour and albumen height were significantly (P˂0.05) affected; with those on Turmeric + Garlic diets having the highest for these parameters. However, the fatty acid variables were not significantly (P˃0.05) affected by the dietary treatments. It could be concluded that the inclusion of PFAs in the diets of laying hens especially at an older age would help to sustain performance with improved quality.

The Effect of Phytobiotics Supplementation and Magnetized Drinking Water on Production Performance and Egg Quality of Laying Hens

“…Phytobiotic is NGPs that are derived from plants. Phytobiotic has some functions such as growth-promoting effect, antimicrobial activity, anti-inflammation activity and improve the performance and egg quality of the laying hens (Ayeni et al, 2020;Gheisar and Kim, 2018;Hazrati et al, 2019). Phytobiotic optimizes the gut system and improves the performance production and egg quality of laying hens by utilizing the bioactive compounds which are contained in the plant.…”

Efficacy of Moringa oleifera Lam. extracts and Pediococcus pentosaceus, Lactobacillus acidophilus, Lactobacillus plantarum probiotic during starter period on growth performance of male broiler chicken

“…Phytobiotics have proven to have several functions, such as a growth-promoting effect, antimicrobial activity, anti-inflammation activity and improving performance. [2][3][4][5] They allows to control micro-organism growth in the digestive tract of poultry by increasing the metabolic activities in the body, making them potential feed additives in poultry.…”
