Khaki Campbell Ducks

Background: In present scenario cost of common feed ingredients like maize and soybean are in rising trends due to less availability. Thus, the feed industry is forced to search the way to combat the feed cost. Rice Distillers Dried Grains with Solubles, is one of the best alternative source of feed ingredient. It has good source of energy, protein, vitamins and minerals. Presently, rice as subtract for bioethanol production is increasing due to its relative lower price, higher production and easy availability leads to increased availability of co-product rice distillers dried grains with solubles. In present study Nutrisigma® has been used. ‘Nutrisigma®’is rice distillers dried grains with solubles produced by IFB Agro Industries limited, Kolkata. In consideration of the above fact, the present experiment was designed to study the effects of “Nutrisigma®” on productive performance of Khaki Campbell ducks. Methods: A total of nine hundred female Khaki Campbell ducks of the same genetic background and of comparable body weight at 72 wks of age, were randomly assigned into 3 dietary treatments that is Control (C), Treatment 1 (T1) and Treatment 2 (T2) each with 3 replicates of 100 ducks and they were studied for 60 days. All the experimental ducks were fed 120gm/duck/day concentrate mixture. Treatment group received (T1 group @ 3 gm/duck/day and T2 group @ 5 gm/duck/day) ‘Nutrisigma®’ in addition to concentrate mixture. Result: In our experiment egg production (%), fertile egg production per day, fertility%, hatchable egg weight (gm) and hatchability% were increased significantly (p is less than 0.05) in treated groups compared with control group. Better economic efficiency was observed in T1 group compared to T2 and control groups. In conclusion, Nutrisigma ® with concentrate mixture could be used economically up to 5gm/head/day (T2) without any harmful effect on productive performance, however, the use of 3 gm/head/day (T1) is more economical than 5 gm/head/day.

Dietary Treatments

Alternative growth promoters are able to not only effectively replace the traditional use of antibiotics but also provide additional health benefits for livestock and reduce food safety concerns. This study investigated the effects of dry Hydrastis canadensis on the laying performance and fecal microbial community of laying hens. Twenty-four Lohmann (LSL, white layer strain) hens were reared from 40 to 48 weeks of age and randomly allotted to four dietary treatments (six birds/treatment). The dietary treatments comprised a basal diet with no treatment as control, a basal diet plus 0.6% powder of dry Hydrastis canadensis roots (R) or leaves (L), and a basal diet plus 0.6% powder of a mixture of dry Hydrastis canadensis roots and leaves (1:1, LR). No mortality was observed in the whole experimental period. The results indicated that albumen height in the LR group was significantly greater than that in the control group. The diet supplemented with Hydrastis canadensis had no significant effects on egg production rate, egg weight, eggshell strength, eggshell thickness, Haugh unit, or yolk height during the whole experimental phase. However, principal coordinate analysis, comparative heat map analysis, and cluster dendrogram analysis of cecal microbiota showed distinct clusters among the groups treated with Hydrastis canadensis and the control group. Regarding blood biochemical parameters, serum cholesterol levels were significantly lower in all Hydrastis canadensis-treated groups compared with those in the control group. Moreover, serum low-density lipoprotein levels were lower in hens supplemented with the leaf of Hydrastis canadensis. The abundances of the phyla Fusobacteria and Kiritimatiellaeota were increased (p < 0.05) in laying hens fed with 0.6% Hydrastis canadensis leaves, whereas the abundance of the phylum Firmicutes in cecum digesta decreased in response to treatment with Hydrastis canadensis roots and leaves. The relative abundance of the Fusobacterium genus was higher in the LR group compared with that in the control. On the contrary, we found a different trend in the Synergistes genus. The potential influences of these microbiota on the performance of laying hens were discussed. The results demonstrate that Hydrastis canadensis can improve the egg albumen height and modulate the cecum digesta microbiota composition of laying hens.

: The effects of dietary inclusion of distillers dried grains with solubles in laying hen diets with and without exogenous enzyme mixture (EEM) on performance and egg characteristics were evaluated. One of the main objectives of this study was to examine the effects of distillers dried grains with solubles (DDGS) and enzyme cocktail on egg yolk fatty acids. The study used total of 144 Hisex Brown laying hens in a 4 × 2 factorial arrangement, including four levels of DDGS (0, 6, 12, and 18% of diet) and two levels of enzyme cocktail (0 or 250 mg EEM/kg of diet) through 32–42 weeks of the age. The inclusion of 18% DDGS was associated with the worst (p ≤ 0.001) egg production and the lowest daily feed intake. Numerically, hens fed 6% DDGS diet consumed more feed and had the greatest egg production. The best feed conversion ratio (FCR) was recorded in the control, while the worst was recorded in the 18% DDGS group. Compared with EEM-free diets, EEM supplementation improved FCR by about 2.79%, but the difference was not significant. Shell thickness and shell percentage were significantly increased in hens fed 6% DDGS diet compared to other groups. Egg weights in the 6% and 12% DDGS groups were significantly higher than those in the control and 18% DDGS groups. Non-significant increases in shell and albumin percentages were recorded in groups fed EEM-supplemented diets. The interaction effect of DDGS and EEM was significant (p ≤ 0.01) for the majority of egg characteristics. As dietary DDGS level increased, yolk color density increased. Elevating DDGS level up to 18% increased yolk cholesterol, total fat, and total unsaturated fatty acids. The effects of EEM supplementation on egg yolk fatty acid composition and the interaction effects between DDGS and EEM were not significant. Considering these results, it could be concluded that DDGS is an acceptable feed ingredient in layer diets and that the maximum inclusion level of DDGS should not exceed 12% of the whole diet.

The study was conducted to determine the effect of antiprolactin drug (Bromergon®) and Peppermint (Mentha piperita L.) on broodiness, laying performance and egg quality in indigenous hens. The effect of modulation of prolactin concentration on egg production, sequence length and inter sequence pauses were studied by analyzing the oviposition records. Total sixty indigenous laying hens (30-40 weeks of age), were assigned for treatment with peppermint solution and Bromergon®. Sixty laying hens were randomly divided into 4 groups (A, B, C and D) and each group remained 15 hens. Group A was kept for control, Group B was treated with bromocriptine (Bromergon® SANDOZ) orally @ 640 ?g per bird per day, Group C with 50% peppermint solution @ 10 g per bird orally and Group D was with peppermint and Bromergon® combined at previous dose. Over the course of trial, incremental dietary peppermint (Group C) significantly (p?0.05) increased egg production, body weight of treated indigenous hens than other groups. Egg shell percentage, thickness and haugh unit of hens fed diets supplemented with peppermint were greater than that of hens fed the control diet. However, peppermint supplementation did not influence other egg quality characteristics like albumen and yolk percentages and albumen height. The treated birds had comparatively longer sequences and fewer pauses. It is concluded that the physiological pauses occur during ovulatory sequences can be disrupted effectively using Bromergon® and peppermint. Prolactin levels modulated which may interfere with follicular recruitment and subsequent oviposition thereby improves egg laying potential of the indigenous hens.Asian J. Med. Biol. Res.

A 12-week study was conducted at the Teaching and Research Farm of the Obafemi Awolowo University, Ile-Ife to evaluate the effect of dietary inclusion of LAYPLUS® (LP) on fertility and egg parameters of female Japanese quails, Coturnix coturnix japonica. Two hundred and ten birds of average weight of 167.75±3.94g were used for this study, and they were allocated randomly into seven treatment groups and replicated thrice. Group 1 served as control without inclusion of LAYPLUS®, while groups 2, 3, 4 and 5 had 250 mg/kg, 500 mg/kg, 750mg/kg and 1000mg/kg inclusion of LP and group 6 had 240mg/kg of vitamin E, respectively, and group 7 clomiphene citrate. Eggs were collected daily and egg production was calculated on a bird-day basis. The data obtained were analyzed using one-way ANOVA. There was significant increase (p<0.05) in the egg production parameters namely egg weight, egg laid per hen and percentage laying rate of LP500mg/kg compared with other groups. The highest percentage egg production was by the LP500mg/kg at 57% while the lowest was by the LP250mg/kg at 41%. There was no significant difference in the egg weight and Haugh unit among the supplemented birds and the control group. There was significant difference among the treatments in the percentage hatchability of the eggs with LP500mg/kg eggs recording the highest value of 95.68%. It can be concluded from this experiment that supplementation of the feed with LP at 500mg/kg had beneficial effect on quail production through improved effect on egg production and hatchability.

This study investigated the dietary effects of Moringa oleifera leaves supplementation on egg quality, laying performance, excreta ammonia concentrations and serum biochemistry of laying chickens during the late laying period. A total of 240 64-week-old Hy-Line Brown hens were assigned to four treatment diets including Moringa oleifera leaves at 0, 3, 6 or 9 g/kg, respectively, for eight weeks. The treatments had twelve replicates with five hens each. The results revealed that incremental dietary Moringa oleifera leaves significantly increased (p < 0.01) egg weight, production, and mass through 64–68, 68–72 and 64–72 weeks of age. Simultaneously, feed conversion ratio was significantly improved (p < 0.01) with Moringa oleifera leaves supplementation compared with the control. Haugh units and the thickness of eggshells significantly improved as a response to diets supplemented with 3, 6 and 9 g/kg Moringa oleifera leaves at 72 weeks of age. Interestingly, excreta ammonia concentrations, serum cholesterol, aspartate transaminase and alanine aminotransferase significantly decreased by Moringa oleifera leaves supplementation compared with the control group. In conclusion, introducing Moringa oleifera leaves supplementation at 3, 6 and 9 g/kg increased egg production, eggshell quality, Haugh units, and decreased serum cholesterol, triglycerides, excreta ammonia concentrations besides serum liver enzymes, uric acid and creatinine. Overall, based on the observed results, Moringa oleifera leaves supplementation was very promising and these leaves could be used as an effective feed additive in laying hens’ diet during the late laying period.

In the context of increasing awareness on the dietary supplementation of organic selenium in commercial poultry production and ensuring safe egg production, the present study investigated the effects of selenium on the pharmacokinetics of the therapeutic use of florfenicol and enrofloxacin from perspectives of laying performance, selenium deposition in eggs, and drug residue in plasma, organs, and eggs. A 2 × 3 factorial arrangement with two kinds of drugs (florfenicol vs. enrofloxacin, 200 mg/kg) and three levels of dietary organic selenium SCIP (selenium conjugated to insect protein) (0, 2, and 5 mg/kg) was designed together with a blank control group. Healthy Hy-Line Brown laying hens (n = 252, 40-week-old and 90.0 ± 1.7% of egg production rate) were randomly allocated into one of seven treatments with six replicates and six hens per replicate. The experiment lasted for 42 days and consisted of three periods (adjusted stage, depositional stage, and eliminating stage) of 14 days each. These stages entail feeding of the laying hens with basal diets, addition of drugs and selenium synchronously into the diets, drug withdrawal from diet, and supply of selenium uninterruptedly in the diet. Egg production and feed intake were recorded on daily and weekly bases, respectively. The selenium content in egg yolk, egg white, and whole eggs and the drug residues in eggs, plasma, liver, kidney, and breast muscle were determined on days 2, 3, 5, 6, 7, 9, 11, and 14 of the depositional and eliminating stages. There was no significant difference (p &gt; 0.05) in egg production among the dietary treatments, but feed intake decreased significantly (p &lt; 0.05) in the drug treatment group compared to other groups. Dietary organic selenium decreased the residue of drugs in tissues and eggs, while the metabolism and deposition of selenium in laying hens were suppressed due to drug effects. The results of the present study are of significance to enrich the knowledge of the pharmacokinetics of florfenicol and enrofloxacin in laying hens and ensure the quality of poultry products.

Abstract In the era of increased antibiotic resistance and ever stricter control on antibiotic use, it is urgent to develop green, safe and non-residue alternatives to antibiotics applied to the poultry industry. To this end, we supplied the potential Lactobacillus Plantarum (L. Plantarum) fermented Astragalus in the diet of laying hens, with a final addition of 3‰. Its effects have been assessed on laying performance, egg quality, antioxidant and immunological status and intestinal microbiota, and are compared to the control group, to the Astragalus group containing 3‰ unfermented Astragalus, and to the L. Plantarum group containing 2% L. Plantarum (1 × 108 CFU/mL). During the second half of the experimental period (15 to 28 days), the egg production rate was significantly higher in the fermented Astragalus group than that in the other groups, with the fermented Astragalus group having the lowest feed conversion ratio. No significant difference (P > 0.05) was observed among treatments on egg quality. Fermented Astragalus-treated hens exhibited significantly increased catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in serum, and reduced malondialdehyde (MDA) in serum. Furthermore, fermented Astragalus supplementation resulted in a significant increase in ileal microbiota abundance relative to control. In conclusion, feeding laying hens with L. Plantarum fermented Astragalus has beneficial effects on production, antioxidant potential, immunity and ileal microbiota. L. Plantarum fermented Astragalus is expected to be a novel feed additive used in poultry production.

This experiment was carried out to determine the effects of using L-carnitine and humate alone or in combination in quail diets on laying performance, egg traits and blood parameters. A total of 280 Japanese quails aged 10 weeks, divided into one control group and three treatment groups, were used. The diets of the first, second and third treatment groups were supplemented with 100 mg L-carnitine/kg, 1.5 g humate (Farmagülatör® Dry Plus)/kg and 100 mg L-carnitine + 1.5 g humate/kg, respectively. The experimental period lasted 16 weeks. The addition of L-carnitine and sodium humate alone or in combination did not significantly affect body weight, feed consumption, egg production, feed conversion ratio, mortality, egg-shell thickness, egg yolk index and the percentages of egg-shell, albumen and yolk. Egg weight increased (P < 0.001) with L-carnitine supplementation. The values of egg albumen height (P < 0.05), egg albumen index (P < 0.01) and egg Haugh unit (P < 0.05) were increased with humate supplementation. Egg cholesterol content and blood serum parameters were not affected by the supplementation of L-carnitine with or without humate. The results in this study demonstrated that L-carnitine supplementation increased egg weight while humate addition increased egg albumen index and egg Haugh unit of laying quails. However, the combined administration of L-carnitine and humate did not have any significant effects on the parameters measured.
