“…In previous studies, starch contents of triticale varied from 630 to 730 g/kg DM (Leon et al, 1996;Hughes & Cooper, 2002;Çiftci et al, 2003). The contents found in the current study were lower than these values, the highest starch content being in cultivar H127, a trial name of triticale cultivar that was later commercialised as 'Bogong'.…”

Ten high-yielding cultivars of triticale obtained from a breeding group at the University of New England, harvested in 2008 and 2009, were assessed for nutrient composition and nutrient digestibility. The cultivars tested were AT528, H20, H127, H128, H157, H249, H418, H426, JRCT74 and Tahara. Their nutrient characteristics, including dry matter, crude protein, crude fat, ash and gross energy, starch content and composition, and concentrations of non-starch polysaccharides, minerals, phytate-P content and amino acids, were determined. The in vitro digestibility and viscosity during digestion were also measured. There was low variability between the cultivars tested and harvest years (the difference between wet and dry conditions) had little effect on nutrient composition.

“…In a laying hen feeding experiment based on four dietary types (600 g wheat, 600 g triticale, 330 g maize + 300 g triticale and 300 g wheat + 300 g triticale kg −1 ) and two enzyme levels (0 and 1 g kg −1 xylanase-based enzyme), there were no significant effects (P > 0.05) of diet type, enzyme supplementation or diet type × enzyme supplementation interaction on hen performance. 51 Grindazym reduced eggshell weight and thickness of both experimental and control birds (P < 0.05). There was no clear explanation for these effects, and more work needs to be done to clarify the possible reasons.…”

“…There are some reports indicating that enzyme supplementation of laying hen diets had no influence on eggshell quality and thickness. 51,52 However, in a study by Jaroni and Scheideler 53 it was noted that the specific gravity of eggs declined significantly (P < 0.01) in diets with xylanase supplementation compared with diets without enzyme supplementation; the authors suggested that this decline could have been a result of improved egg size (as indicated by increased albumen and yolk) and correspondingly thinner shells.…”

Cumin seed meal as an alternative to wheat bran in commercial laying hen diets

To evaluate the nutritional significance of cumin seed meal (CSM) as a commercial poultry feedstuff on laying hen performance and quality of laid eggs, an experiment was conducted using 144 (48-week-old) laying hens receiving diets containing 0, 25 and 50 g CSM kg −1 with or without polyethylene glycol (PEG 6000) and xylanase enzyme (Grindazym  GP 15000) for 9 weeks. Body weight on the first and last days of the experiment and daily egg production and egg weight and weekly feed intake during the first, fifth and ninth weeks of the experiment were recorded. Shell weight, shell thickness, Haugh unit and yolk colour were measured during the last week of the experiment. The results showed that inclusion of CSM in laying hen diets had no negative influence on the parameters measured compared with the control diet (P > 0.05), but enhanced egg yolk colour (P < 0.05). PEG increased the daily feed intake of birds receiving CSM diets (P < 0.01) and tended to enhance daily egg production and egg weight, although not significantly. Grindazym decreased shell weight and thickness of laid eggs (P < 0.05) and tended to increase hen body weight, but had no influence on other parameters measured. The results demonstrated that CSM can be substituted for wheat bran in layer diets at 25 or 50 g kg −1 dietary inclusion level without any adverse effect on hen performance or egg quality, and might enhance egg yolk colour. In view of the low price of CSM, it could be concluded that inclusion of CSM in the diet might be beneficial to the commercial laying hen industry and reduce the overall cost of egg production.

“…Since developing embryos utilize calcium from the eggshell, developmental stage can be expected to cause eggshell thinning (Vanderstoep and Richards, 1970;Bunck et al, 1985;Bennett, 1995;Castilla et al, 2007;Karlsson and Lilja, 2008). Additionally, eggshell thickness appears to be influenced by many factors including genetics, egg colour and size, the time the eggs spend in the uterus, female characteristics (condition, age, stress, health status), and the diet of the females (Kennedy and Vevers, 1973;Nys et al, 1991;Francesch et al, 1997;Ciftci et al, 2003;Boersma et al, 2004;Riczu et al, 2004;Castilla et al, 2007Castilla et al, , 2009bBirchard and Deeming, 2010). More recent studies have shown that Mycoplasma infection also produced egg abnormalities and eggshell thinning (Feberwee et al, 2009).…”
