This experiment was conducted to investigate the effects of different levels of L-carnitine on productive performance, egg quality and blood parameters in laying hens. Forty-eight Hy-Line W-36 egg Layers were weighed at 90 weeks of age and randomly allocated into 16 cages (three hens per cage). Four dietary treatments were prepared by supplementing L-carnitine (0, 50, 100 and 150 mg/kg of diet)...

in this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of leghorn-type laying hens (hy-line w-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. the treatment groups were: 1) control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

The objective of this study was to determine the effects of various levels of dietary black cumin seed on egg production, egg weight, feed conversion ratio, egg shell quality, and egg yolk cholesterol. In this study, eighty 27-wk-old laying hens (Hyline-5 White) were randomly assigned into 4 groups with 4 replicates of 5 birds each (20 laying hens per group) and fed diets supplemented with 1, 2...

The African green monkey has previously been found to be a promising model for the study of atherosclerosis. We have compared the plasma and HDL cholesterol response to dietary manipulation in the two subspecies of African green monkeys (vervets and grivets) most often imported for biomedical research purposes. Twenty vervets and 20 grivets were fed, in succession, diets containing safflower oi...

In this experiment, a total of 128 Hy-line W36 hens at 63 weeks of age were used. The hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of Spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. All birds were housed in commercial cages, had ad libitum access ...

Fish oils rich in n-3 fatty acids lower plasma triglyceride profoundly but the effect on plasma cholesterol is not clear. This study tested the capacity of MaxEPA oil to modify the rise in lipoprotein cholesterol during cholesterol-rich diets. Six subjects were tested with three diets: 1) habitual (P/S 0.47, cholesterol 710 mg/d); 2) fish oil (40 g/d MaxEPA, P/S 1.62, cholesterol 190 mg/d); 3) ...

This study aims to the productivity and quality of Isa Brown chicken eggs given tuna fish oil in ration. The design used was a completely randomized (CRD) with 200 chickens 4 treatments 5 replications each replication consisted 10 chickens. P0 : Ration without use oil, P1 0.25 % P2 ration 0.50% P3 0.75% oil. feed is composed ingredients, namely corn, bran, KLS Super Plus. variables observed inc...

This experiment was carried out to evaluate the effects of feeding green tea powder on laying performance and egg quality in hens. A total 180 “Tetran Brown” laying hens aged 40 weeks were assigned to 6 treatments in a completely randomized design. Each treatment consisted of five replicates accommodating six layers per replication. The experimental diets were a negative control containing no g...

The practical usage of untraditional feedstuffs such as sunflower meal (SFM) in laying hens nutrition developing countries has received considerable attention. SFM is a by-product the oil industry and been progressively added to bird’s diets. Sunflower gaining great interest feed ingredient due its eminent crude protein content, low anti-nutritional compounds, price. current experiment was aime...
