Abstract.  A research has been conducted to study the potency of probiotics as antibiotic replacements in terms of egg production and income over feed cost at commercial duck farms. The treatments were control, probiotic administration (P1=5 and P2=7 ml/kg feed), and antibiotic administration (A1=0.5 and A2=1 dose). Thus, there were 5 treatment units which were replicated 4 times.  Each unit had 30 laying ducks, so in total there were 600 local laying ducks. Parameters observed were egg production as Hen Day Production and egg mass. Hen Day Production was measured by calculating the number of eggs, divided by the number of female ducks in percentage. Egg mass was calculated by the number of eggs multiplied by the weight of the eggs, divided by the number of ducks. The results showed that egg production in control, P1, P2, A1 and A2 was 50.95%, 62.90%, 60.85%, 56.75% and 65.40% respectively. For egg mass, the data were 36.07+3.25; 44.58+3.63; 42.64+4.31; 41.44+3.76; and 45.27+4.57 respectively. Statistical analysis revealed that, for both parameters, there was a significant difference (P<0.05) between control and treatments but not a significant difference among treatment groups. It seemed that probiotics and antibiotics had similar effects on Hen Day Production and egg mass. It can be concluded that probiotics could replace antibiotic administration for laying ducks in terms of egg production.

Production Response

The effect of photo-induced changes on egg production and reproductive performance of female guinea fowl was studied by exposing the birds to three photo-regimens, namely natural daylight all day for 12 weeks (NDL), 8 hours of light per day for 8 weeks (8L-16D) plus supplementary light for 16 hours per day for 4 weeks (16L-8D) (RSL), and provided natural daylight all day for 8 weeks plus supplementary light at 16 hours per day for 4 weeks (SL). Weight gain during the pre-laying period was similar (P>0.05) in all the treatment groups between 20-36 weeks of age. The reverse was the case during the laying period between 36-52 weeks, which coincided with the age at sexual maturity. Feed intake was similar (P>0.05) for the NDL and SL groups during the pre-laying period but the RSL group had significantly lower (P<0.05) feed intake than the others. Overall laying mortality was lowest in the RSL birds. There was no significant difference (P>0.05) in body weight for all the groups. Age at first egg was significantly lower (P<0.05) in the RSL (207 d) than in the NDL (249 d) and SL (235 d) birds which were similar (P>0.05). The guinea fowls which received 8 weeks of restricted light (RSL) responded more rapidly in terms of day-to-first-egg after exposure to 16 hours of light and achieved significantly higher (P<0.05) level of egg production than the other two groups. The overall economy of production, in terms of cost, revealed that RSL birds performed better than the NDL and SL, in that it cost N36.58 and 127.05 more to produce each NDL and SL guinea fowl at point of lay respectively. The results indicate that different light regimes altered the time during which egg production response took place and apparently affected the genetic potentials of the groups with regard to egg mass and total number of eggs laid during the period covered by this trial.

The experiment was conducted to study the comparative performance of Gririaja birds reared on different feeding regime in Nepal. A total of 384 Giriraja birds of aged 40 weeks were assigned to four treatment groups in four replications with 24 birds (20 female and 4 male) per replication over a period of 180 days. The birds of control group were provided with 130g of feed in confinement. In group 1, 10% feed was replaced by green seasonal forage mainly oat and birds were kept on scavenging, while in group 2, 10 % feed was replaced by similar forage but the birds were in confinement. However, in group 3, birds were provided 10 % less feed on scavenging without forage supplementation. The result showed that the feed consumption required for dozen of egg production was lower (P<0.01) at 2610 g/bird in group 1 and higher (3114 g/bird) in control group. The birds kept in control and in group 1 was found significantly (P<0.05) superior in egg production as compared with the second and third treatment groups (15.05 and 16.15 vs. 15.55 and 14.31 in number, respectively). There was no significant difference on egg weight between the groups. Feed cost for dozen of egg production was recorded $1.17 and more gross returns from sale of eggs ($ 0.27) was observed in treatment group 1 but less return ($ 0.04) was obtained from control group. The result showed that rearing of Gririaja birds with forage supplementation having the facilities of outdoor range is a good profitable venture, considering the minimum feed consumption and feed cost with maximum egg production.Bang.

Jasus Edwardsii

The annual commercial catch from the Southern Zone of the South Australian rock lobster (Jasus edwardsii) fishery is ~1900 tonnes, representing ~50% of total landings from south-east Australia. A single minimum legal size (MLS) of 98.5 mm carapace length (CL) exists across the entire zone. Fecundity (F), size at onset of maturity (SOM) and relative reproductive potential (RRP) of female rock lobsters were investigated in two major fishing regions, i.e. the North Southern Zone (NSZ) and South Southern Zone (SSZ) with a view to providing a basis for future fine-scale spatial management of the resource. F ranged from 45,292 to 466,800 eggs per female and increased proportionally with CL according to the relationship: F = 0.0584 × CL3.1642. F was significantly higher in the NSZ compared to the SSZ but was attributed to differences in lobster size between regions. There was no significant difference in the number of eggs · g−1 of egg mass between areas. SOM, estimated as the size at which 50% of females reached sexual maturity (L50) was higher in the NSZ (104.1 mm CL) compared to SSZ (92.3 mm CL). Approximately 20% of lobsters above the MLS in the commercial catch in the NSZ were under the L50 estimate. RRP, as a measure of egg production, was calculated for each size-class from the product of F, SOM and population length–frequency. The modal RRP size-classes in the NSZ were 117.5–122.5 mm CL, while in the SSZ it was 97.5–102.5 mm CL. Only 6% of RRP was contributed by female rock lobsters below the MLS in the NSZ, compared to 34% in the SSZ. Regional differences in SOM and RRP in the Southern Zone of South Australia suggest that different MLSs may be beneficial, particularly if the fishery is to be effectively managed at finer spatial scales.

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.

 In order to examine the effect of phytase supplementation in the diet of laying hen this experiment was conducted with 30 commercial hybrid Babcock-380 layers of 73 weeks of age. The hens were grouped into 3 treatment groups and given microbial phytase (Rena Phytase 400) at levels 2.5, 1.5 and 0 (control) g/kg feed in addition to their basal diet (110 g commercial pellet/day). Records on egg production/group/day, egg mass weight/day, body weight of hens at the end of experimental period were taken and analysed. Results revealed that hen house egg production (HHEP) and egg weight (EW) varied (p<0.05) among the treatment groups but level of phytase did not affect (p<0.05) body weight of hens. Both HHEP and EW were in order of 2.5>1.5>0 g/kg feed phytase group and all the means were significantly (p<0.05) different from each other within treatment groups. Microbial phytase supplementation in layer ration proved to be beneficial in terms of egg production and egg size even after 72 weeks of age of hens. Layer farms in Malaysia can use this technology to earn more profit.

The study was conducted at Bangladesh Livestock Research Institute to evaluate the productive and reproductive performances of 4 pure lines conserving for the production of next generation. A total of 2000 pedigree hatched day-old chicks were wing banded and reared up to 40 weeks of age. Data were kept on daily feed intake (g/bird/day), weekly body weight (g), age at sexual maturity (days), daily egg production (%) and egg weight (g). There were highly significant differences (p<0.01) in body weight at 38 weeks, age at sexual maturity, egg production up to 40 weeks and egg weight at 38 weeks of age among the treatment groups. There were no significant differences (P>0.05) in fertility, hatchability, dead in germ, sound chick and dead in shell percentage among the treatment except cull chicks where L1 showed the highest percent of cull chicks.  Egg production at 23-28 and 35-40 weeks of age differ significantly (p<0.01) except at 29-34 weeks of age (p>0.05). Significant variations for FCR observed at 35-40 weeks of age while it was non-significant (p>0.05) at 23-28 and 29-34 weeks of age. It is revealed that line-2 is superior in terms of egg production, age at sexual maturity and egg mass where line-1 was better in terms of FCR value. Considering the results it may be concluded that there are significant variations exists regarding egg production performances among the experimental pure lines, thus could be utilized successfully for the production of high yielding strains through proper breeding programme.

The purpose of this study was to determine the effect of adding coated sodium butyrate at various levels to the rations of laying hens on their performance, egg quality, and some blood parameters. In this study, a total of 72 laying hens at the age of 60 weeks were fed for 56 days with the control ration and the rations containing sodium butyrate at various levels (300, 600, and 1200 mg/kg). The study was carried out in 4 treatment groups, each with 6 replicates. As a result of the study, there was no statistically significant difference between the treatment groups in terms of live weight change, egg yield, feed consumption, feed conversion ratio, egg weight, and egg mass. The addition of sodium butyrate to the rations of laying hens did not have a statistically significant effect on the egg shell breaking strength, eggshell ratio, shell thickness, egg shape index, albumen-yolk index, damaged egg ratio, and egg yolk colour criteria (L*, a*, and b*). Whereas there was no statistically significant difference between the treatment groups in terms of the levels of cholesterol, HDL, albumin, Ca, and P; some statistically significant differences were observed in terms of the levels of serum globulin, total protein, and uric acid. Based on the findings of the study, it was concluded that there was no need to add sodium butyrate to the ration for improving the performance and egg quality in the laying hens at the age of 60 weeks.

The present study aimed to determine the effects of borax (Na2B4O7.10H2O) addition on the changes of histological cerebrum imaging in the brains of white mice (Rattus norvegicus). The current research was an experimental study with randomization of 24 white mice that were divided into four treatment groups with five replications. Borax was dissolved for each treatment with a dose of 19 mg/mouse/day, 26 mg/mouse/day, and 37 mg/mouse/day, and it was administered orally for 14 days. Then, it was analyzed statistically using the Kruskal-Wallis test. The statistical analysis results suggested that there were significantly different results in each treatment group. The control treatment with an administration dose of 26 mg/rat/day had a significantly different result in the worst cloudy swelling degeneration of cerebrum in histopathology imaging on Wistar rats (Rattus norvegicus). Using the Mann-Whitney test, it was found that the dose of borax at 37 mg/rat/day led to significant difference, compared to the other treatment groups, which means that 37 mg/rat/day of borax caused the worst pyramidal cell necrosis in histopathology imaging of the cerebrum on white mice. Borax exposure on Wistar rats (Rattus norvegicus) can cause cloudy swelling at a dose of 26mg/head/day, and pyramidal cell necrosis at a dose of 37 mg/head/day.

The aim of this study was to determine the effects of adding orange peel (PKY), lemon peel essential oils (LKY) and PKY+LKY (respectively 300, 300, 150+150 mg/kg) to laying quail diets on performance, egg internal and external quality parameters and hatchability parameters. The eight-week trial was conducted in 20 subgroups, with 4 treatment groups and 5 replications for each treatment, and a total of 120 Japanese quails at 10 weeks of age were randomly distributed, with 6 quails (4 females, 2 males) in each subgroup. Feed intake with the addition of LKY to the diet, egg production and egg mass with the addition of PKY + LKY decreased significantly compared to the control group, and the eggshell breaking resistance with the addition of LKY and PKY + LKY increased significantly compared to the control group. However, the addition of LKY, PKY and PKY+LKY to the diet did not affect hatchability and reproduction parameters. According to these results, the addition of 300 mg/kg PKY and 300 mg/kg (150+150) PKY+LKY to breeder quail diets had an effect on the increase of eggshell qualityi, although the performance was adversely affected.

The objective of this study was to evaluate different inclusion levels of distillers dried grains with solubles (DDGS) from corn in the diet of quails. A total of 210 japanese quails (Coturnix coturnix japonica) were distributed in a completely randomized design of five treatments and six replicates, with seven quails per experimental unit. The treatments used were: control feed; inclusion of 5, 10, 15 and 20% of DDGS. The variables assessed were: feed intake, feed conversion per dozen and egg mass, egg production, egg weight, specific gravity, yolk color and economic analysis. Data were analyzed by regression model and Dunnett’s test at 5% probability. For individual feed intake, laying rate, and feed conversion per egg mass, specific gravity and yolk color by color fan, there was effect caused by inclusion of DDGS (p < 0.05), but the other variables did not show significant difference. By Dunnett’s test, for feed intake, feed conversion per egg mass, specific gravity and digital colorimeter’s L parameter, there was effect (p < 0.05). As for economic analysis, DDGS presented low cost. It can be concluded that DDGS can be used in feed at a 20% level without impairing the performance and quality of quails eggs.
