The average minimum maximum room temperatures recorded from 14 42 days age were 26.1 37.5 °C, respectively, with relative humidity ranging 51% 55%. Five DEB treatments supplying 0, 50, 150, 250 350 (Na + +K –Cl − ) mEq/kg diet prepared by adding NaHCO 3 and/or NH 4...

A study was conducted to evaluate three different levels of Azadirachta indica dried leaf meal, using diets supplemented with 0 (negative control), 1.25 g antibiotic/kg (positive 1.25, 2.5 and 5.0 meal/kg feed. The chicks were randomly divided into 15 separate floor pens (each 10×15 feet) each comprising 20 (replicates) per treatment group following completely randomised design. At 28 42 d BW feed conversion ratio (FCR) determined. d, five birds pen slaughtered measure dressing percentage...

With the growing awareness among general public, demand for food products rich in omega-3 polyunsaturated fatty acids (n-3 PUFA) has increased over years. Hen eggs enriched with n-3 PUFA are serving this purpose. Several earlier trials indicated that addition of PUFA-enriched feed stuffs laying hen rations readily promoted contents egg yolks. A major increase was noticed linolenic acid content yolk and also long chain PUFA. The cholesterol decreased to some extent by feeding diets hens....

The present study was conducted to evaluate the effects of feeding whole linseed on laying performance and egg characteristics in hens kept at high ambient environmental temperatures (average 34 ºC; diurnal temperature range 26 ºC 41 ºC). Two hundred forty 38-wk-old white Leghorn were fed diets containing 0, 5, 10 or 15% (as a source n-3 polyunsaturated fatty acids) for period 12 weeks. Egg production recorded daily, while feed intake monitored weekly basis. results demonstrated that...

Feed production with different milling methods, thermal treatment, and particle size may influence mineral digestibility retention in eggs. The present study investigated the impact of roller (R) hammer (H) mills, mash (M) expandate (E) fine (F) coarse (C) sizes, on apparent ileal absorption (AIA) total (ATD) calcium, phosphorus, magnesium, zinc, manganese, copper iron yolk, albumen, shell. A 384 hens (Lohmann Brown), 19 weeks old, were assigned using a randomized design 2×2×2 factorial...

AbstractMoulting is a natural phenomenon in birds during which they replace old plumage with new feathers, reduce feed intake, lose body weight and suspend reproduction. Moulting laying hens can be induced by using photoperiods, deprivation or restriction diets containing minerals variable amounts of other ingredients. Induced moulting result higher egg production improved quality. It reduces mortality, costs investments farms hatcheries. While withdrawal has been most effective way to...

A number of 252, 70 week old, single comb white leghorn hens at the end their first production cycle were divided into two groups: group-I; molted by fasting and group-II; high dietary zinc to obtain second third cycle. Sampling was carried out 5%, peak 5% Serum decreased cycle, while increased in zinc-molted group. copper manganese Egg albumin as well cycles during yolk but iron Eggshell group, eggshell
