The effect of replacing imported fish meal (FM) with poultry visceral offal meal (PVOM) in the diets of 200 Isa brown laying hens on their performance characteristics and economy of egg production during 22 to 38 weeks of age were examined. PVOM replaced FM on an equal proteins basis at the grade levels of 1.18, 2.37, 3.55 and 4.73% of diet B,C,D and E respectively. The control diet A contained 4% fm as the sole source of animal protein. All diet contained ca 16% crude protein while their calculated metabolisable energy was ca 2600 kcal/kg diet. Observations were made at interval of 4 weeks and entire 16 weeks period. Neither feed intake or egg weight was affected (P>0.05) by dietary treatment during the 4, 28-day and entire 16- weeks periods. The result of feed intake: egg weight ratios on the respective diets for each 28-day period and entire study period showed significant difference (P<0.05) and similarity in the values of the parameter between some dietary treatment but the effect of PVOM inclusion level on this parameter did not follow any consistent trend to undermine the result of other parameters. Mean daily egg production was higher (P<0.05) on diet a than the rest diets during 22 to 26 week of age but these difference gradually disappeared towards 38 week of age. Daily egg yield per 10 birds on diets D and E were similar but lower (P<0.05) than on the rest of the diet whose egg yields were also similar for the entire 4-month period. The performance data for the 4-month period on mean daily feed in take (g/bird) stood at 78.81 (A), 80.32 (B), 85.31 (C), 81.70 (D) and 75.88 (E) while the feed intake: egg weight ratios were 1.46 (A), 1.51 (B), 1.58 (C) 1.52(D), and 1.41 (E). Mean daily egg yield 6.85, 6.88, 6.73, 6.25 and 6.14 for diets A,B,C,D and E respectively while mean (g) were 54.15(A), 53.23 (B), 54.00 (C), 53.75(D), and 53.88 (E) for some period. PVOM could not replace FM beyond 59.25% of it proportion in the control diet without detrimental effect feed intake and egg size but could further reduce feed cost.

This study was conducted to know the production performance of laying hen by using different graded level of linseed. At 56 weeks of age, a total of 160 laying hens were raised up to 63 weeks of age. All hens were fed a basal corn soyabean meal diet. The experiment was allowed 4 dietary treatments (T0, no addition of whole linseed in the basal diet; T1,  addition of 5% whole linseed; T2, addition of 10% whole linseed and T3, addition of 15% whole linseed) with 5 replications and per replication contains eight hens. Egg production, feed intake, egg weight of each treatment was recorded. Egg samples were collected and analyzed for egg quality. The results showed that egg production and egg mass (kg) exhibited for all dietary treatment groups were unaffected (P>0.05) by feeding linseed to the laying hens. Feed Conversion Ratio (FCR) was found significant difference within the four dietary group (P<0.05). Egg quality aspects such as yolk weight, egg weight, HU and yolk index were not differed significantly (P>0.05) among treatments.  A trend for lower yolk weight was observed in birds fed 10% linseed, where as the highest yolk weight percentage was recorded in control diet. There was no statistical difference among the different diets for yolk index. The results of the present trial suggested that feeding linseed to the laying hens has no detrimental effects on egg production and egg quality.

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%.

Abstract Previous studies examining the effects of deoxynivalenol (DON) intake in pigs have largely focused on young animals or have been over a short period of time. The objective of the present study was to determine the effects of long-term feeding of DON contaminated diets on growth performance of grower-finisher pigs. A total of 240 mixed-sex pigs (35.9 ± 1.1 kg) were group housed in 6 pigs/pen (n = 10/treatment) and were randomly assigned to 1 of 4 dietary treatments for 77 d. Diets consisted of a control diet (CON) containing no DON or a diet containing 1, 3, or 5 ppm DON (DON1, DON3, or DON5) achieved by adding DON-contaminated wheat and wheat screenings at the expense of clean wheat. In the grower period, DON5-fed pigs had reduced average daily gain (ADG) compared to CON, with DON1 and DON3-fed pigs being intermediate P &lt; 0.05). There was no effect of dietary treatment on ADG in the finisher period (P &gt; 0.05). Overall the entire study, DON3 and DON5-fed pigs had similar and reduced ADG (P &lt; 0.05) compared to CON and DON1, which did not differ (P &gt; 0.05). Feed intake was reduced in DON-fed pigs in the finisher period (3.12, 2.97, 2.96, and 2.88 ± 0.05; P&lt; 0.05) and in DON3 and DON5-fed pigs overall (2.62, 2.55, 2.47, 2.47 ± 0.03; P &lt; 0.05) compared to CON, with no overall effect observed in the grower period. There was no effect on feed efficiency in any period (P &gt; 0.05). The decrease in performance resulted in reduced final body weight in DON3 and DON5-fed pigs, compared to CON, with DON1-fed pigs being intermediate (P &gt; 0.05). Overall, the effects of DON-intake on performance were variable and generally occurred rapidly after initial exposure and appear to be largely due to the reduction in feed intake.

Abstract The present study aimed to evaluate the feeding performance of juvenile marble goby (Oxyeleotris marmorata) on acidified diets. Five fish meal-based diets at various pH levels (2.5, 3.2, 4.3, 5.3, and 6.0 (control)) were prepared, and each of them was fed to 10 wild-caught O. marmorata juveniles (body length 7.7–9.3 cm; each fish was placed in an aquarium, hence each dietary treatment was in 10 replicates) for 20 days. Throughout the feeding trial, O. marmorata juveniles showed clear increments in the daily ingestion ratio (IR) values of AD 2.5, AD 3.2, and AD 4.3. The control diet and AD 5.3 were almost totally rejected by the fish. On day 20, the IR of AD 2.5 (0.46) and AD 3.2 (0.36) were significantly higher (P < 0.05) than those of AD 5.3 (0.1) and the control diet (0.02). In addition, 70% of fish fed AD 2.5 achieved a high IR value (0.6 – 1.0), and this was the best result among all the treatments (AD 3.2, 60%; AD 4.3 50%; AD 5.3 and control, 10%). These results suggested that acidified diets can be used to wean O. marmorata juveniles, and the recommended pH level was 2.5.

Two experiments were conducted concurrently to assess the effect of different levels of fresh and dry Tridax procumbens on performance of layers. 720 Hbbard layers were grouped into 6 treatments of 60 birds per treatment in each experiment. The treatment in consisted of 0, 2, 4, 6, 8 and 10% inclusion rates of fresh and dry Tridax procumbens in first and second experiments, respectively. Tridax leaves, irrespective of the form and level had no significantly (P > 0.05) effect on egg production, egg weight and feed intake. Inclusion of Tridax either in fresh or dry form increased (P < 0.05) yolk colour, while the yolk colour intensity was more pronounced (P < 0.05) in the dry Tridax than the fresh Tridax experiment.

Vitamin E and zinc are necessary for preventing free radical damage to phospholipid membranes, enzymes and other important molecules. The objective of this study was to evaluate the effect of dietary vitamin E and zinc levels on performance and lipid oxidation in fresh and stored eggs of laying duck. A total of 90 of 22 weeks old ducks were randomly divided into 15 experimental units by assigning a completely randomized design with 5 treatments and 3 replications. The treatment diets were R1 (control diet), R2 (R1+40 IU vitamin E), R3 (R1+80 IU vitamin E), R4 (R1+100 ppm organic zinc), and R5 (R1+200 ppm organic zinc).The experiment was carried out for 8 wk. Parameters observed were feed intake, egg production, egg weight, feed conversion ratio, and Thiobarbituric Acid Reactive Substances (TBARS) value. The results showed that increasing of vitamin E from 40 IU to 80 IU and zinc from 100 ppm to 200 ppm did not affect feed intake and egg weight. Otherwise, the dietary Vitamin E and organic zinc significantly decreased (P<0.05) feed conversion ratio and significantly increased (P<0.05) egg production and decreased (P<0.01) TBARS values. It is concluded that dietary 40 IU vitamin E or 100 ppm organic zinc could increase the performance of laying ducks and dietary 200 ppm organic zinc was more efective to be antioxidant than 40 and 80 IU vitamin E.

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.

Three experiments were undertaken to investigate the coccidiostat, nicarbazin, on reproductive performance of layers. In trial 1, levels of 0, 5, 10, 20, 40, 80, 125, and 200 ppm nicarbazin were fed to White leghorn laying hens for 5 wk. By the 2nd week of nicarbazin treatment, egg production was significantly reduced in birds fed 125 and 200 ppm (P < 0.05). Similarly, increasing levels of nicarbazin resulted in decreasing egg weights (P < 0.01) and feed intake was significantly decreased. However, by the 2nd week post-nicarbazin treatment, egg production, egg weight, and feed intake had returned to normal. Nicarbazin had no effect on egg shell deformation or body weight. Nicarbazin had a marked effect on hatchability; levels of 125 and 200 ppm reduced hatchability significantly (P < 0.01) as well as producing an increased incidence of malpositions and malformations. When nicarbazin was withdrawn from the diet, hatchability returned to pretreatment values although malpositions and malformations were still in evidence. Experiments 2 and 3 were designed to study the effect of nicarbazin on production of brown-shelled eggs. In the 2nd experiment 0, 5, 10, 20, and 40 ppm of dietary nicarbazin resulted in significant loss of shell color at 20 and 40 ppm, whereas in exp. 3 with levels of 0, 80, 125, and 200 ppm, brown eggs lost virtually all their color. It is concluded that the adult White Leghorn bird can tolerate up to 125 ppm nicarbazin without significant (P < 0.01) loss of reproductive performance although lower levels show a trend for reduced production. Hatchability is depressed with nicarbazin levels in excess of 80 ppm, while trace levels will produce a visual loss of color in brown-shelled eggs.

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 (<I>P</I> < 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 (<I>P</I> < 0.001) egg weight (62.1 g vs. 60.7 g). The yolk proportion in egg weight was the highest (26.0%, <I>P</I> < 0.001) and the albumen weight ratio was the lowest (64.2%, <I>P</I> < 0.001) in group R8. Iodine supplementation improved (<I>P</I> < 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 (<I>P</I> < 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 (<I>P</I> < 0.05) in eggs of hens fed RS. The addition of I did not affect flavour, odour, taste or overall acceptability.
