PSIII-3 Metabolizable utilization of energy and protein for egg production by addition of dried citrus pulp and eggshell into diet for laying quails (coturnix japonica)

Abstract This study aimed to evaluate the effects of adding 0% (T1), 6% (T2), 12% (T3) and 18% (T4) of a mixture (83% dried citrus pulp (DCP) and 17% eggshell) into a sorghum-soybean meal-limestone based diet for laying quails, on production efficiency and quality of egg. Thirty-two quails were individually housed and randomly assigned (n = 8) to the four experimental diets, during the first 5 week of the laying cycle. Quail LW and feed intake were recorded weekly. Produced eggs were weighed (n = 457) and egg mass production recorded. Proportions of albumen, yolk and shell, egg yolk color, and shell thickness, were determined (n = 55/treatment). On week 5, total excreta of 24 laying quails (n = 6) were collected throughout 96 h, to determine metabolizable utilization of DM, energy, crude protein and ash. Statistical analyses were performed with SPSS® software. Initial and final LW, feed intake and egg production were similar (P >0.05) among treatments. Egg mass was higher (P < 0.05) in T2 than T4. Egg weight of quails fed T1 and T2 was higher than others (P < 0.05). The eggshell of quails fed T2 was thicker (248 vs 236 μm; P < 0.05) than T1. Eggshell proportion of quails fed the mixture was higher (P < 0.05) than in T1 (11.3 vs 10.5%). Yolk proportion of T1 was higher (P < 0.05). The b* parameter was lower (P < 0.05) for T1. Metabolizable utilization of dietary DM (72.1%) and energy (68.8%) of T1 was 13% higher (P < 0.05) than T4, however protein (avg 41.4%) and ash (avg 46.7%) utilization were similar (P > 0.05) among treatments. In conclusion, adding up to 12% of the mixture (83% DCP and 17% eggshell) in quail diets, resulted in similar egg production parameters, and metabolizable utilization of dietary DM, crude protein, energy and ash, however improved thickness of eggshell, compared to the control diet.

The aim of this study was to evaluate the effects of vegetable glycerin on performance and egg quality of red-egg layers in the second production cycle. A total of 252 Hy-Line Brown layers weighing 1.919 ± 0.095 kg, at 90 weeks, were used in a completely randomized design with six treatments and seven birds per replication. The experiment lasted 84 days. Treatments consisted of a control diet (no glycerin) and five diets with increasing levels of vegetable glycerin (2, 4, 6, 8, and 10%). The following variables were evaluated: feed intake (g/bird/day); egg production (%); egg weight (g); egg mass (g/bird/day); conversion per egg mass (kg kg) and per dozen eggs (kg/dz); percentages of albumen, yolk, and shell; eggshell thickness (mm); and egg specific gravity. (Y = 67.69 + 54.23X, R2 = 0.78) and egg mass (Y = 44.84 + 42.87X, R2 = 0.66) improved linearly with the glycerin levels. A quadratic effect was observed (Y = 114.11 + 336.96 X – 3,169.6 X2, R2 = 0.52) on feed intake. In conclusion, glycerin can be used to partially replace corn in diets for layers in the second production cycle at inclusion levels of up to 10%.

A total of 45 laying hens were fed a control diet, or one of four diets containing 50 g kg–1 fish silage and different levels of fish fat (1.8, 8.8, 16.8 or 24.8 g kg–1), to determine the effect of fish silage and fish fat in the diet on performance and egg quality. Fish silage did not affect feed intake, egg production, fatty acid composition of yolk, yolk color or sensory quality of eggs, compared with the control. The diets with 16.8 or 24.8 g kg–1 fish fat decreased feed intake (P < 0.001), egg production (P < 0.001), and hen-day egg production (P < 0.04), and increased yolk color index (P < 0.003). The proportions of the fatty acid C22:1 (P < 0.001), and PUFA as the sum of C18:2 n-6, C20:5 n-3, C22:5 n-3 and C22:6 n-3 (P < 0.02) in egg yolk were highest for the fish silage diets with 24.8, 16.8 or 8.8 g kg–1 fish fat, and lowest for the diet with 1.8 g kg–1 fish fat. Proportions of C18:1 (P < 0.001) and C20:1 (P < 0.001) were lowest for the diets with 16.8 or 24.8 g kg–1 fish fat. Egg yolk cholesterol did not differ among treatments. The diet with 16.8 g kg–1 fish fat resulted in a more intense egg albumen whiteness as measured by the sensory study, compared with the other diets (P < 0.05). There was a linear relationship between dietary fish fat level and increased off-taste intensity of egg yolk (P< 0.03). Key words: Fish silage, fish fat, laying hens, egg production, egg quality

This study was carried out to evaluate the energy levels in the diet to obtain better performance rates and quality of eggs from laying hens in the second production cycle. One hundred and eighty Bovans Goldline laying hens with 62 weeks of age were used during four 28-day periods. A completely randomized experimental design was used with four metabolizable energy levels (2,650, 2,725, 2,800, 2,875 and 2,950 kcal/kg), each with six replicates of six birds. The energy level of diet did not affect the weight of the egg, yolk, albumen and eggshell, the percentages of yolk, albumen and eggshell, yolk color and egg specific gravity. Feed intake, egg production, egg mass and feed conversion per egg mass and per dozen eggs increased significantly with increasing levels of metabolizable energy. Feed intake decreased linearly as the energy level in the diet increased. The metabolizable energy levels showed a quadratic effect on egg production, egg mass and feed conversion per egg mass and per dozen eggs. The metabolizable energy level of 2,830 kcal/kg was the most appropriate to promote better performance and quality of eggs from laying hens in the second production cycle.

Effect Of Feeding

The objective of the experiment was to evaluate the effect of the feeding of 80 g/kg (R8) and 100 g/kg (R10) of untreated rapeseed (RS) on egg quality including sensory quality in comparison with a control diet without rapeseed (R0). The addition of iodine (I) was also evaluated (1 mg/kg (R10) vs. 3 mg/kg (R10+I)). “Double zero” RS was used. The contents of energy and crude protein were almost the same in the diets. Laying hybrid ISABROWN was used in the experiment. The quality of eggs was analyzed 11 times every 28 days, from 19 to 64 weeks of age. 30 eggs per each group were always analyzed. Boiled eggs were assessed twice around the peak of egg production. Egg weight decreased (P < 0.001) with the increased level of RS (62.9 g, 61.8 g and 60.7 g, respectively). A reduction in egg weight in R8 and R10 diets resulted in the lower weight of albumen and eggshells. The addition of I to R10 diet increased (P < 0.001) egg weight (62.1 g vs. 60.7 g). The yolk proportion in egg weight was the highest (26.0%, P < 0.001) and the albumen weight ratio was the lowest (64.2%, P < 0.001) in group R8. Iodine supplementation improved (P < 0.001) yolk weight (15.7 g vs. 15.3 g). The proportion of RS in the diet did not affect the eggshell strength. An increase in the level of I improved (P < 0.001) eggshell quality (strength 36.1 N vs. 34.0 N and thickness 0.386 mm vs. 0.363 mm). Taste and overall acceptability were lower (P < 0.05) in eggs of hens fed RS. The addition of I did not affect flavour, odour, taste or overall acceptability.

ABSTRACTThe use of antibiotics in chicken feed is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the physical and chemical quality of Lohmann chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were no differences between treatments on the performance of laying hens (egg production, egg weight, egg mass, feed conversion); physical quality (eggshell, egg yolk, egg white, shell thickness, egg yolk, Haugh unit, egg index) and chemistry (superoxide dismutase production, thiobarbituric acid reactive substances (TBARS) and Lohmann chicken egg cholesterol) but there was a difference in feed intake. The uronic acid extracted from S. crassifolium has not been able to increase the production and quality of Lohmann chicken eggs.Keywords: lohmann chicken, quality of eggs, Sargassum crassifolium, uronic acid

Pullets were brought into production on a low-protein corn, soybean meal diet to which various nutrients including essential amino acids, choline, corn oil and feathermeal were supplemented. Production commenced between 18 and 20 wk of age and up to at least 60% production, hens fed the low protein diets (10% CP) produced at least as many eggs and as great an egg mass as these given a 17% protein corn, soybean meal control diet. Pullets fed the corn, soybean meal test diets, peaked at around 80% as compared to slightly over 90% for the control. Egg production immediately fell for birds fed the test diets to around 70% for most of the test treatments. Body weight remained constant or fell after peak production for birds fed the test diets as compared to a normal increase for birds on the control diet. Egg size increased for the test diets at a rate which was comparable to that of the control birds. In a second experiment, with older hens, supplementation of the 10% protein test diet with methionine, lysine, arginine and tryptophan, resulted in intakes of these amino acids which met NRC minimum requirement levels. However, egg mass output was reduced approximately 11% compared to the 17% protein control diet. While intakes of several essential amino acids fell below requirement levels, the degree that valine was calculated to be deficient in both experiments corresponded closely with the reduction in egg mass output of hens fed the test as compared to the control diet.

The present study was conducted to evaluate the optimum level of dietary inclusion and the form of feeding sapu-sapu fish (SSF) as a single protein source for feed components of small holder Mojosari duck farming. A total of 180 twenty four wk-old laying ducks were fed with two forms (sun-dried and ground-fresh) and three levels of SSF (10, 20 and 30%) from 24 to 32 wk of age. Experimental diets were formulated containing 105.1; 141.5 and 177.9 g/kg crude protein and 3078; 3065 and 3052 kcal metabolizable energy (ME) /kg diet. Production performance and egg quality were measured. The form of SSF had a significant effect (P<0.0001) on feed intake, egg production, feed conversion, egg mass and egg number except final body weight. No significant effects (P>0.05) were found on all of the performance parameters measured due to feeding levels of SSF except feed intake and final body weight. The interaction of form and feeding level was significant (P<0.05) on egg and body weights. Low performance and egg quality were observed in the birds fed a diet containing the dried SSF. It can be suggested that local ducks required 20% SSF as a single protein source for maximum egg production (41.2%) and total egg number per wk (3.1 eggs/bird/wk) during 8 wk of rearing period. Egg quality can be improved by feeding the fresh SSF. However, due to be sufficiently better processing technique, the dried SSF would be potential to replace the common fish for laying ducks.

Egg Fertility

The effect of two classes of exogenous enzymes on the egg fertility traits, egg production efficiency and oviduct micro-structure of laying hens was evaluated. Forty-five laying hens (30-weeks old, 1.32-1.40 kg) were randomly allotted into three dietary treatments with fifteen birds per treatment (five birds each in three replicates per treatment) in a completely randomized design. Diet one served as the control diet. Diet two (FS diet) contained a nutrient-targeted exogenous enzyme preparation (Fullzyme®) at 200 g/ton, while diet three (DS diet) contained a mycotoxin-targeted exogenous enzyme preparation (Detoxizyme®) at 500 g/ton. Data on fertility traits (egg volume, length and breadth, weight, yolk diameter, albumen height, air cell, shell thickness, Haugh’s unit, and egg-lay), and egg production (feed intake, egg lay, egg lay efficiency, and feed cost per egg laid) were collected for 42 days. At the end of the experiment, three randomly selected birds per group were euthanized, and their oviducts were harvested and processed for histopathology. Hens fed enzyme supplemented diets had significantly (p < 0.05) better egg fertility traits. Feed intake in the control group did not vary (p > 0.05)from feed intake in the DS or FS group. However, feed cost per egg laid and egg-lay efficiency was higher in the control diet group than in the FS group or DS diet group. No pathologies were observed in the oviduct of birds fed enzymes supplemented or control diet. Exogenous enzymes in diet improved egg fertility traits and production without altering the oviduct micro-structure of Layer hens.
