Appraisal of Hematological Indices and Humoral Immunity in Commercial Laying Hens Fed Rations Consisting Cottonseed Meal and Sodium Bentonite
The objective of this study was to evaluate the effects of cottonseed meal (CSM) treated with sodium bentonite (SB) on certain blood components and immune response of laying hens. A 3 × 3 factorial arrangement with 3 levels of SB (0, 10, and 20 g/kg of diet) and 3 levels of CSM (0, 100 and 200 g/kg of diet) were used within 9 dietary treatments of 4 replicates each. Nine mash diets were fed to ...
متن کاملRequirement of Digestible Sulfur Amino Acids in Laying Hens Fed Sorghum- and Soybean Meal-Based Diets
Two experiments were done to evaluate the effect of increasing levels of dietary digestible methionine (Met) and Met:cysteine (Met:Cys) ratio on the productivity of Hy-Line W-36 laying hens fed sorghumand soybean meal-based diets. In Exp. 1, 160 hens from 68 to 75 weeks of age were assigned to four dietary levels of digestible Met (0.20 0.24, 0.28 and 0.32%). The digestible total sulfur amino a...
متن کاملPhytase supplementation improved P utilisation of the laying hens fed barley - oats - soybean meal based diets
The objective of the study was to determine the effect of Quantum Blue phytase on P utilisation and bone parameter in laying hens fed barley, oat and soybean meal based diets. Over a period of 40 days 64 laying hens (from 29 weeks of age) were distributed to 4 treatments (8 cages, two birds each). Experimental diets with no inorganic P added were supplemented with 0, 150, 300 or 1200 FTU phytas...
متن کاملPerformance and nutrient utilization of laying hens fed low-phosphorus corn-soybean and wheat-soybean diets supplemented with microbial phytase.
Two experiments were conducted with laying hens (Lohmann Brown) in an individual cage system and with single feeding conditions. Experiment 1 (n = 24) was a performance trial (22 to 61 wk) to evaluate phytase effects on performance and nutrient utilization in corn-soybean meal (CSM1) and wheat-soybean meal (WSM1) basal diets (0.12% NPP; 3.1% Ca) supplemented (300 U/kg) with an experimental micr...
متن کاملProcessing, Products, and Food Safety I
to determine the effect of graded levels of low glucosinolate CM, up to complete replacement of soybean meal, on the performance of laying hens. Wheat-based diets were formulated on a digestible amino acid basis with 4 levels of CM (0 to 16.7%) and fed to 3 commercial laying hen strains, Lohmann Brown (LOH), ISA Brown (ISA), and Lohmann LSL (LSL). Rations were fed from 19 to 59 wks of age, with...
