One hundred and forty-four (144) 45 week old laying hens of Black Nera strain were used in an experiment to determine the effect of replacing dietary fish meal (FM) or soybean meal (SBM) with shrimp waste meal (SWM) on the performance of laying birds. The birds were randomly allocated to three groups of 48 birds each. Each group was further divided into four replicates of twelve (12) birds each. Three iso-proteinous and iso-caloric diets were formulated such that a practical layer diet which served as the control diet (diet I) contained soybean meal (SBM) and fishmeal (FM) as the major protein sources. In diet 2, the FM in the control diet (25gkg') was replaced by SWM (40.43kg ') (protein for protein), while SWM (201.5gkg"') was made to replace the SBM (180gkg') in the control diet (protein for protein) in diet 3. The birds were given feed and water ad libitum. The experiment lasted 10 weeks. The performance in terms of feed intake, hen-day production, egg number and efficiency of egg production (i.e. dozen egg per kg feed) indicated that birds on diet ? (SWM/SBM) performed equally well as those in the control diet. Performance was however significantly (P<0.05) reduced when SWM replaced the protein supplied by SBM in which case about 20% of SWM was employed. There were no significant differences in the albumen height, shell thickness, egg shape index and haugh units of eggs produced. Birds on diet 3 however had the lowest (P<0.05) values of egg weight, egg length, egg breadth and the weights of yolk and albumen, Results of this study showed that shrimp waste-meal at minimal level (4%) can successfully replace fishmeal in a practical layers diet without negatively affecting performance or egg quality of the birds. However, replacing 180g SBM/kg with 201.5g SWM/kg diet had detrimental effect on performance probably because of the high level of SWM that was employed.

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

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

Main Effects

The effects of peeling and limestone flour level on the utilisation of Alocasia macrorrhiza corm meal (ACM) by laying hens were investigated. Maize-based diets with two concentrations of limestone flour (40 and 60 g/kg) and diets containing 200 g peeled and unpeeled ACM meal/kg with the same levels of limestone flour were fed to five replicate pens containing 10 20-week-old Shaver brown pullets (1635 ± 148 g), each for 105 days. Results showed no interaction or main effects of ACM or limestone concentration on feed intake, egg weight, egg mass, feed conversion efficiency, egg shape index, surface area and Haugh unit (P &gt; 0.05). Feeding whole ACM with 40 g limestone/kg diet reduced hen-day production and shell thickness (P &lt; 0.05) but this was overcome by increasing limestone concentration to 60 g/kg diet. Peeled ACM with both concentrations of limestone flour maintained laying performance and egg quality. We concluded that feeding 200 g whole ACM depresses egg production and shell quality in laying hens, but increasing dietary limestone concentration overcomes this adverse effect. The concentration of limestone flour in the diet has no effect on laying performance. Higher inclusion levels of ACM, calcium source and level that will maintain laying performance and reduce feed cost need to be investigated.

Effects of dietary Garcinia kola meal (bitter kola) on the performance and egg quality characteristics of laying hens were investigated. Four layers diets were made such that diet T0 (control) contained no Garcinia kola meal while diets T2.5, T5.0 and T7.5 contained 2.5%, 5.0% and 7.5% Garcinia kola meal, respectively. Each diet was fed to a group of 30 laying hens at 30 weeks of laying life for 84 days, using completely randomized design (CRD). Each group was further sub-divided into three replicates of 10 hens each. The layers on T2.5 and T5.0 diets added significantly (P < 0.05) less body weight than those on T0 and T7.5 diets. There were no significant differences in their feed intake (P > 0.05). T2.5 significantly (P < 0.05) depressed hen-day egg production but enhanced egg weight. Feed conversion ratio (g feed/ g egg) was not affected by the treatments (P > 0.05). Egg quality indices (egg shape index, egg specific gravity, Haugh unit, egg shell thickness, albumen index and yolk index) were not affected by the treatments (P > 0.05). Egg shell index was significantly (P<0.05) enhanced by Garcinia kola meal. At 2.5% level, it significantly enhanced percent albumin and reduced percent yolk (P<0.05). Cost of egg production (N/kg eggs) was adversely increased as the level of Garcinia kola meal increased.

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.

<p class="p1">The research aimed to determine the effect of shrimp waste on the quality of duck eggs. The research used 80 female ducks aged 21 weeks which were randomly distributed into four treatments consisted of four replicates of 5 ducks each. The ration consisted of yellow corn, rice bran, soybean meal, fish meal, premix, grit, vegetable oil and shrimp waste. The dietary treatments were formulated to contain 0 (control), 3, 6, and 9% shrimp waste. The experiment was performed for 3 periods of 28 days. Egg quality was assessed for 3 consecutive days on d 26,27 and 28 of every periods. The data were analysed using Analysis of Variance and continued with Duncan’s test for different results. Theuse of 9% shrimp waste in ration increased (P&lt;0.05) score of yolk colour from 6.94 to 7.79, but did not affect other measured variables. It can be concluded that shrimp waste enhanced yolk colour of duck eggs.</p>

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.

The objective of this study was to compare the effect of sodium selenite (SS) and selenium yeast (SY) on performance, egg quality, and selenium concentration in eggs and serum biochemical indices in laying hens. Seven hundred twenty healthy Roman laying hens (21 weeks old, 18 weeks in lay) with a similar laying rate (90.27% ± 1.05%) were randomly divided into 5 groups with 6 replicates of 24 hens each. Five diets were prepared as a 1+2×2 factorial arrangement with control and two sources of Se at two levels. Control diet (control) was prepared without adding exogenous selenium (analyzed basal Se content of 0.178 mg/kg). The other four diets were prepared with the control diet supplemented with SY or SS at 0.3 mg/kg (low; L) or 0.5 mg/kg (high; H) to give 5 diets designated as control, SY-L, SY-H, SS-L, and SS-H. The analyzed selenium content in the SY-L, SY-H, SS-L, and SS-H diets were 0.362, 0.572, 0.323, and 0.533 mg/kg respectively. The pre-trial period lasted 7 d, and the experimental period lasted 56 d (30 weeks old), during which the egg production, egg quality, and hen serum parameters were measured. Results showed that selenium source and level had no effect (P > 0.05) on average daily egg weight and feed conversion ratio (FCR). However, the laying rate was different at the L and H levels of supplementation, regardless of source, such that hens that were supplemented had a higher performance than that of the control, and the H level of supplementation lead to a higher laying rate than that of the L level (P < 0.05). There was a difference in average daily feed intake (ADFI) with an interaction in selenium source and level (P < 0.05), such that SS-L was higher than other selenium supplemented treatment or control. There were no significant differences in egg quality (P > 0.05); at the high level, SY had higher egg yolk selenium compared with SS. However, within SY, adding 0.5 mg/kg selenium led to higher egg yolk selenium than 0.3 mg/kg selenium (P < 0.05). Moreover, adding 0.3 mg/kg SY, 0.3 mg/kg, or 0.5 mg/kg SS to the basal diet had no significant effect on the selenium content in the egg (P > 0.05). There were no significant differences in serum biochemical indices among the five groups (P > 0.05). In conclusion, adding a high level of selenium in the diet of laying hens significantly increased egg production, and addition of a high level of selenium in the form of SY led to a higher deposition of selenium in the yolk than that of SS. These results indicate that adding 0.5 mg/kg of SY in the diet of laying hens would result in Se-enriched eggs.

Adaptation To Captivity

Abstract Seriola lalandi is an important species for aquaculture, due to its rapid growth, adaptation to captivity and formulated diets, and high commercial value. Due to the rise in fish meal (FM) price, efforts are made to replace it partially or entirely with vegetable meals in diets for carnivorous fish. The use of prebiotics when feeding vegetable meals has improved fish health. In this study, four experimental diets were assessed in juveniles, the control diet consisted of FM as the main protein source, the second diet included 2% GroBiotic®-A (FM-P), the third included FM with 25% replacement by soybean meal (SM25), and the fourth consisted in SM25 with 2% of GroBiotic®-A (SM25-P). RNA-seq of the liver tissue was performed, followed by differential expression analysis and functional annotation to identify genes affected by the diets. Growth was not affected by this level of FM replacement, but it was improved by the prebiotic. Annotation was achieved for 78,826 transcripts, of which 135 were up-regulated and 78 down-regulated among all treatments compared to the control. Transcriptomic profiles of control samples were clustered with those from fishes fed SM25 and SM25-P diets, and the most differentiated group was that one fed the FM-P diet. SM25-P showed the least amount of differentially expressed genes, maintaining general transcriptomic profiles of control diet in the liver, therefore this diet is a potential economic alternative to the FM diet, for S. lalandi juveniles. Assessment of the effects of this diet along the digestive tract is recommended.
