Background: Egg production efficiency is typically measured through age and body weight at sexual maturity, egg number and egg weight during certain production periods. Increased egg weight and number of eggs are the primary purpose of the laying bird breeding programmes. Partial period analysis enhances selection process as the variations occurring throughout the bird’s productive life are identified and helps in the selection decisions. The current study aimed to study the genetic parameters such as heritability, phenotypic and genetic correlations to improve egg production performance and egg quality traits in Japanese quail reared at the Central Avian Research Institute (CARI).Methods: In present investigation, data recording was carried out from the Japanese quail population at experimental quail farm, CARI during 2019-2020. The individual mating was conducted between 180 sires and 180 dams of three varieties of Japanese quails were randomly selected from the base populations to develop first generation of experimental population. The hatched chicks were wing banded and the pedigree details recorded. For economic traits such as egg production and egg quality estimation, 40 sires and 40 dams were selected and parameters were evaluated. Result: In this present investigation, egg number from 10-16th week of age exhibited moderate to high heritable values. Egg weight was estimated moderate heritability traits. In egg quality traits, all values were moderate to high heritable values except yolk density in all the three varieties.

Enzyme Supplementation

The present study was conducted to assess the effect of supplementation of Multi-enzymes with lysophospholipids on production performance of pure line White Leghorn layers. Body weights before and after the experiment did not differ significantly across the experimental diets. Irrespective of the dietary treatments, the birds gained 3.83 per cent of live weight relative to its initial body weight. Mean per cent Hen housed egg production was significantly (Pis less than 0.05) higher in diet supplemented with 0.10 MEC-L than other groups. Mean egg weight and average daily feed consumption during 25 to 35 weeks of age indicated no significant effect of enzyme supplementation. Average daily feed consumption per bird in control, 0.05 % and 0.1% multi-enzyme supplemented groups was 108.13, 105.66 and 107.67 g respectively and birds offered control diet recorded numerically more feed intake than enzyme supplemented groups. Comparatively low feed per egg was observed in 0.10 per cent group followed by 0.05 per cent group which offers economic benefits than control diets. However, the egg quality traits between different dietary enzyme supplementation groups showed no significant difference.

This study was to investigate the effects of Bacillus subtilis on production performance and bone pathophysiological characteristics of layers. Twenty-four 48-week-old Lohmann Pink-shell laying hens were randomly divided into two groups: a basic diet (control) and the basic diet mixed with Bacillus subtilis (0.5 g/kg) for a 60-day trial. Statistically, independent-sample t-test was used to assess the treatment differences. The results showed that Bacillus subtilis supplementation improved the percent of marketable eggs (p < 0.05) with reduced numbers of broken and soft-shelled eggs but had no effects on egg weight, height of albumen, yolk color, and Haugh unit (p > 0.05). Bacillus subtilis supplement also elevated maximum load (p = 0.06), maximum stress (p = 0.01), stiffness (p < 0.01), and Young’s modulus (p < 0.01) but suppressed maximum strain (p = 0.06) in the femur. In addition, compared with control birds, phosphorous concentration (p < 0.01) was reduced in serum at day 61 but increased in the femur (p < 0.05) in Bacillus subtilis fed birds. Bacillus subtilis fed birds also had lower magnesium concentrations in both femur (p = 0.04) and feces (p = 0.09). Furthermore, Bacillus subtilis increased plasma estrogen concentration (p = 0.01) and femur TNF receptor superfamily member 11b (OPG) expression (p < 0.05) but reduced plasma IL-1 (p < 0.01) and TNF-α (p < 0.01) concentrations. These results indicate that Bacillus subtilis could be used as a health promotor to reduce overproduction-induced inflammation and associated bone damage and to increase marketable egg production. The data provide evidence for developing a management strategy to use Bacillus subtilis as a feed additive to improve marketable egg production and health and welfare status of laying hens.

This experiment was conducted to evaluate the egg production performance in zebrafish (Danio rerio) in different pH treatments. Zebrafish were reared continuously 15 days in 3 different pH treatments like control (pH 6.8-7.4), acidic (pH 5.0-6.0) and basic (pH 9.0-10.0) media and then eggs were collected from them. Numbers of egg collection from the acidic and basic media were significantly varied from the control. Collected eggs from acidic, basic and control media were then incubated at different pH treatments ranging from pH 2.0-12.0. Significant differences were observed in hatching rate and time in control medium from two other different treatments.Progressive Agriculture 26:85-89, 2015

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.
