An experiment was conducted to evaluate the effect of graded levels of Chromolaena odorata leaf meal (COLM) on production performance, egg quality characteristics, and serum biochemical parameters on Brahma laying hens. A total of forty-five local laying hens aged 4 to 5 months were weighed and assigned to three treatment groups in a completely randomized design. COLM was used as a supplement and incorporated into the diets at 0, 1, and 2% in diets T0, T1, and T2 respectively. Data were collected on production performance, egg quality characteristics, and serum biochemistry. Results from the study indicate that body weight gain, average weight, and egg volume were low (p<0.05) with treatment T2 compared to control (T0) and the best was obtained with treatment T1. The Haugh unit and percentage hen day production were not negatively affected by the treatment levels of COLM. There were significant (p<0.05) differences in triglyceride, total cholesterol, and urea. Results obtained from this study revealed that the inclusion of 1% of COLM improved the egg quality as well as the health status of the birds without having any detrimental effect on the birds.

Five weeks old layer Japanese quail (Coturnix coturnix japonica) birds (180 nos) were randomly distributed into 4 dietary groups with 3 replicates each for 98 days to study the effect of dietary inclusion of acid ensiled fish waste silage on the production performance, egg quality, feed cost, and serum biochemical profile. Fish meal in control diet was replaced by supplementing fish silage at 3%, 6% and 12% of the diet. Significant increase in egg production (p>0.05) and the lowest feed conversion ratio were recorded when birds were fed with 3% silage. But the egg production or feed conversion ratio was not adversely affected by 6% or 12% inclusion of fish silage. Egg quality attributes like weight, shape index, Haugh score, albumen index or yolk index did not differ significantly with the increasing content of silage in the feed. The yolk concentration increased significantly (p>0.05) with increase in fish silage in the diet. The concentration of serum biochemical constituents (total protein, albumen, globulin, cholesterol, triglyceride, alkaline phosphatase, urea and creatinine concentration) did not vary significantly (p>0.05) among the treatments. Serum glucose concentration was the highest in birds fed with 3% fish silage. Lowest cost of feed/kg egg mass was obtained by inclusion of 3% of fish silage in the diet. It was concluded that acid ensilage from freshwater fish waste can replace fishmeal in layer Japanese quail diets without affecting the production of birds besides resulting in reduction of feed cost.

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.

Feed Form

One of the most important factors that determine feed utilization by chickens is the feed form. Although it is generally believed that pellet diets have a positive effect on chicken growth, there are some studies that have indicated no difference between pellet and mash on chickens performance. This study was conducted to assess the effects of feed form on production performance, egg quality, nutrient metabolism and intestinal morphology in two breed laying hens. Two hundred and sixteen 25-week-old Hy-Line brown (n = 108) and Hy-Line grey (n = 108) hens were selected. Each breed was randomly allocated into two treatments with 6 replications (9 birds in each replication), which were fed mash and pellet diets, respectively. Production performances were recorded daily and egg quality traits were measured every two weeks. At 42 weeks of age, one bird per replication from each experimental group was selected for metabolism determination and intestine morphology observation. Compared with mash diets, pellet diets improved laying rate (p < 0.05), ADFI (average daily feed intake, p < 0.05), egg weight, shell strength, yolk proportion and Haugh unit (p < 0.05) in both breeds and reduced the FCR (feed conversion ratio, p < 0.05) in Hy-Line grey. The apparent digestibility of DM% (dry matter) and CP% (crude protein) were significantly higher (p < 0.05) in both breed laying hens fed pellet than those fed mash. The apparent digestibility of P% (phosphorus) and Ca% (calcium) was higher in Hy-Line grey fed pellet and was higher in Hy-Line brown fed mash. Compared to mash diets, pellet diets increased the VH (villus height), CD (crypt depth) and VCR (ratio of villus height to crypt depth) of the small intestine of Hy-Line grey, and increased the VH and CD of duodenum and ileum of Hy-Line brown. Overall, pellet diets improved production performance and nutrition metabolism through positive changes in the laying rate, feed intake, egg albumen quality and apparent digestibility of laying hens. The current findings provided support for the advantages of feeding pellets during the peak egg laying period for the two popular laying hen strains, Hy-Line brown and Hy-Line grey.
