Effect of dietary supplementation with Morinda citrifolia on productivity and egg quality of laying hens

Abstract

In order to evaluate the dietary supplementation of powdered leaves of Morinda citrifolia on productivity and egg quality of laying hens, a total of 160 White leghorn birds (Hybrid l-33 ) of 27 weeks of age were allotted during 70 days, according to completely randomized design. Dietary treatments consisted of a control diet fed without or with 0.5, 1.0 and 1.5% of powdered leaves of M. citrifolia. Supplementation of 1.0 and 1.5% of M. citrifolia powder increased the egg weight (P<0.05), however, laying intensity, body weight, feed intake, unsuitable eggs, eggshell surface, mass conversion, haugh units and height of the dense white and of the yolk showed no significant differences (P>0.05) among treatments. Also, supplementation of 0.5 and 1.0% of M. citrifolia increased the shell thickness and the yolk color was pigmented by this medicinal plant. It recommended the dietary supplementation of 1.0% of powdered leaves of M. citrifolia on laying hen diets to improve the egg weight, shell thickness and yolk color.Keywords: egg, laying hen, noni, productivity, quality. -Dairon Más-Toro, Yordan Martínez-Aguilar, Román Rodríguez-Bertot, Cesar Betancur-Hurtado, Osmani Rosabal-Nava ResumenPara evaluar la suplementación de polvo de hojas de Morinda citrifolia sobre la productividad y la calidad de huevos de gallinas ponedoras, un total de 160 aves White leghorn (híbridas l-33 ) de 27 semanas de edad, se ubicaron durante 70 días, según un diseño totalmente aleatorizado. los tratamientos consistieron en una dieta control sin o con 0.5, 1.0 y 1.5% de polvo de hojas de M. citrifolia. la suplementación de 1.0 y 1.5% de M. citrifolia incrementó el peso del huevo (P<0.05), sin embargo, la intensidad de puesta, el peso vivo, el consumo de alimento, los huevos no aptos, la superficie de la cáscara, la conversión masal, las unidades haugh y la altura de la clara densa y de la yema no mostraron diferencias significativas (P>0.05) entre tratamientos. Además, la suplementación de 0.5 y 1.0% de M. citrifolia incrementó el grosor de la cáscara y el color de la yema se pigmentó por esta planta medicinal.

Effects of noni leaf (Morinda citrifolia) extract on performance and egg quality of laying quail (Coturnix coturnix japonica)

“…The present study revealed that MC significantly elevates eggshell thickness by 4.75%. Similarly, Toro et al [30] found an improvement in eggshell thickness of White leghorn hen given 1% of noni leaf extract in the diet. For thicker shells, it is important to have a high absorption of calcium and other minerals in the intestine.…”

Fertility and hatchability in duck eggs

“…Egg quality has a significant effect on hatchability, as conditions of the microenvironment during the storage process and early incubation modify both the external and internal quality of eggs (Narushin and Romanov, 2002). External characteristics such as weight, index form (described as maximum breadth to length ratio), shell thickness, porosity, surface quality of the shell and resistance to breakage have been measured (Toro et al, 2015). Internal quality is determined by the height of the dense albumen and the yolk, in addition to Haugh Units.…”

“…Internal quality is determined by the height of the dense albumen and the yolk, in addition to Haugh Units. Haugh units are calculated as: HU=100 log (H+7.57−1.7W 0.37 ) where HU=Haugh units, H=albumin height and W=egg weight (Toro et al, 2015). Heavier eggs are more likely to hatch than those of low weight; however, there are contradictions about the weight of eggs that are not within the average values for incubation (King'ori, 2011).…”

“…Heavier eggs are more likely to hatch than those of low weight; however, there are contradictions about the weight of eggs that are not within the average values for incubation (King'ori, 2011). An increase in weight, shell thickness and internal contents of eggs leads to a higher total weight, which in turn reflects more reserves of nutrients and energy (Toro et al, 2015). Light weight eggs have relatively shorter incubation times (Weis et al, 2011) and the weight of hatchlings is higher from large eggs.…”
