“…Results showed that moulting hens with ZnO salt significantly decreased feed conversion ratio and increased egg production of the birds. This result agrees with reports by Durmus et al [18], Salem et al [19], who observed improvement in egg production and feed efficiency in hens moulted using zinc salts. According to McDaniel and Aske [20], increase in egg production can relate to profit for the egg industry, depending on bird and feed prices and demand for egg.…”

“…According to McDaniel and Aske [20], increase in egg production can relate to profit for the egg industry, depending on bird and feed prices and demand for egg. Increased egg production witnessed in the Zn treated birds may be attributed to the role of zinc in increasing blood plasma sex hormone concentration [18], and its interaction in metabolic processes in the animal like in protein synthesis, carbohydrate metabolism, reproduction, enzyme activation and growth [21]. In addition, increased post moult egg production in hens may be accounted for by the decline in the production of shell-less egg during the same period [12].…”

The aim of this study was to evaluate the ability of using zinc oxide salts to induce moulting, and their effects on post moult performance and organ characteristics of laying hens. Two hundred (75 weeks of age) Isa Brown hens were randomly assigned to five Treatments (T) groups of 40 hens, each namely; T 0 -non-moulted hens and T 1 , T 2 , T 3, T 4 , representing moulted hens fed, respectively, 0.5%, 1.0%, 1.5% and 2.0% Zinc Oxide (ZnO) supplementation per kg diet for 14 days. Organ evaluations of the hens were carried out 7 days post moult. Body weight loss and decline in feed intake of the birds were higher (P<0.01) for moulted hens. Cessation of egg production occurred earlier (P<0.05) in the same groups of birds. During post moult, the moulted hens exhibited greater (P<0.01) percentage body weight gain, when compared with the non-moulted hens. Feed intake and hen-day egg production of birds on 1.0%, 1.5% and 2.0% ZnO supplementation was higher (P<0.01), than those of other treatments. Feed conversion ratio was better (P<0.05) for the same groups of birds. Moulting with ZnO treatment influence highly (P<0.01) the number of days to resumption of egg production, with hens on 2.0% ZnO resuming egg production much later than hens on 0.5%, 1.0%, and 1.5% ZnO treatments. The ovary, liver and kidney of the hens were affected (P<0.05) by the dietary ZnO contents. A greenish coloration of the liver was observed in hens fed 1.5% and 2% ZnO supplementation. These results demonstrate that in order to achieve good post moult performance of laying hens in the humid tropics, farmers should practice the use of 1% ZnO inclusion per kg diet, as an effective method to achieve induced moulting. [6][7][8], etc. These alternative methods have been successfully used by scientist to induce moult in hens, and enhance the post moult egg production. Zinc is one of the several micronutrients that have attracted increased attention, because of their important role in maintaining health and nutrients condition. It is essential for physiologic and metabolic functions such as physical growth, immuno-competence, reproductive function, and neuron behavioral development [9]. Although abundant information exists in literature on the practical application of zinc salts as a means of achieving moulting in hen raised under temperate environment, there is a dearth of information on its application in the tropics, especially in most developing countries, where the method is uncommon. The study therefore was aimed at evaluating the effectiveness of using zinc oxide as a moulting agent for laying hens, on organ characteristics, and post moult production performance.

“…Whereas, egg index, shell percent, yolk percent, albumen percent, Haugh unit, and yolk index were not affected by the dietary supplementation. There was no difference in Haugh units, eggshell strength, or egg shape index among the groups (p > 0.05) in response to dietary M. oleifera leaves [34][35][36]. Ebenebe et al [37] reported that adding MOL had no effect on egg shape index that's correlated with the strength of an eggshell and the grade of eggs.…”

The present study aimed to evaluate the effect of dietary Moringa oleifera (M. oleifera) leaves and/or seed powder on laying Japanese quail performance in terms of egg production, egg quality, blood serum characteristics, and reproduction. In total, 168 Japanese quails (120 hens and 48 males) at eight weeks of age in laying period were randomly distributed to four treatment groups, with six replicates per group and seven birds (five hens and two males) per replicate. The first group (G1) served as a control group, while G2, G3 and G4 groups were supplemented with M. oleifera leaves (ML) and M. oleifera seeds (MS) and their combination ((1 g/kg ML; 1 g/kg MS; and 1 ML g/kg + 1 MS g/kg (MSL), respectively). From the results, feed consumption, feed conversion ratio, egg weight, fertility and hatchability from fertile eggs, egg and yolk index, and Haugh unit were not affected by dietary treatments. However, egg production, egg mass, eggshell thickness, and hatchability were significantly increased and blood aspartate transaminase (AST) and urea decreased in the MS treatment. Both triglycerides and total cholesterol were reduced (p < 0.05) in all treatments with ML, MS, and MSL, with no significant differences in alanine aminotransferase (ALT), albumin, total protein, globulin, and A/G ratio among dietary treatment. Our results clearly indicated that the inclusion of M. oleifera seeds in Japanese quail diet significantly increased egg production and improved hatchability, along with some egg quality parameters, and also lowered some blood biochemical components.

“…Taking multiple conditions into account by the selection decisions, the long lasting breeding progress led to the establishment of basically different layer genotypes. There exists a robust knowledge on the production (GARLICH et al, 1984), keeping (NURGIARTININGSIH et al, 2002;MIELENZ et al, 2005;STRUELENS et al, 2005), nutrition (CROSS et al, 1987;SUCHY et al, 1997;DURMUS et al, 2004), behavioural (MACHAL and JERABEK, 2000;RODENBURG et al, 2004) or body compositional characteristics of divergent layer lines. However, comparative studies are mainly performed to test the improvement, reached in genetics, health (resistence), production environment, molting, morphological alterations, handling during depopulation, transportation, and harvesting, nowadays more and more including also animal welfare aspects (MACHAL et al, 1994;HESTER, 2005).…”

A follow-up, comparative study was designed for the description of differences between two divergent laying hen strains, a Leghorn type and a medium heavy body (MHB) genotype (Hy-Line Brown), in chemical body composition and serum biochemical parameters determined at 3, 4, 6, 8, 10, 12, 14, 18, 20, 25, 30, 52 and 72 weeks of age; each time 5 birds of both genotypes were analysed and exterminated for body composition analysis.Resulting from the genotype-associated differences, the bodyweight of the populations differed from week 20 on. In the chemical body composition dry matter content was similar, while crude protein was higher on weeks 3, 8, 10, and after 18 weeks in the Leghorns. Crude fat content was higher in the brown birds (weeks 8, 10, 25, 30). Total serum protein and albumin showed slightly increasing trends, while serum creatinine concentration showed a downward trend in both genotypes, the MHB birds having higher values. Triglyceride concentration showed a drastic step-up at 17 weeks by changing to the pre-layer diet, coupled with marked between-genotype differences. This quick increase was matched by concentration drops in total and HDL cholesterol, the serum HDL cholesterol of Leghorns being always lower. Sodium concentration showed an increasing tendency with body DM content (R 2 =0.914, P<0.001, n=115). The Leghorns tended to show minimally higher Ca concentrations. The γ-GT activity was always higher in MHB birds, indicating a less effective hepatic adaptation to the peak production. Applying discriminant analysis to classify the genotypes, 94.4% of the original grouped cases was correctly classified, using all variables.
