n-3 enrichment of chicken meat. 1. Use of very long-chain fatty acids in chicken diets and their influence on meat quality: fish oil2001 •
Most of the carcass fat and the saturated ones in particular, have a great effect in raising blood cholesterol concentration, which contributes to the process of coronary atherosclerosis, the main cause of coronary heart disease.. In most cases, the lesions attract platelets and fibrin which block the coronary artery and cause ischemia. The consumer has been aware of the health problems associated with consuming the broiler chickens, carcass fat, and so a demand for leaner birds. Accordingly, the poultry industry has been faced with the problem of producing leaner birds and reducing fat deposition in the broiler carcasses in order to meet the consumer demand. At the research level, many scientists have investigated ways of decreasing abdominal and carcass fats in broiler chickens. It has been established that fat accretion is governed by the genetic constitution of the bird, and is closely influenced by the nutritional and management practices, in addition to the effect of environmental temperature, sex, and age. However, most influencing agent in this respect is the dietary factors which include energy level and source, protein level and quality, energy protein balance and feeding system.
Abstract A feeding trial was conducted to evaluate the effect of replacing different levels of solvent extracted rapeseed (Brassica carinata) meal (RSM) for soybean meal (SBM) on dry matter (DM) intake, growth performance, carcass characteristics, and economics of commercial broiler chicks. Three hundred thirty day-old Hubbard classic unsexed commercial chicks with initial body weight of 43.56 ± 0.66 g were used for the experiment. Chicks with completely randomized design were distributed to 15 pens of 22 chicks each, which was further randomly distributed to 5 treatment rations. Treatments were replacement of RSM for SBM with the percentage of 0, 25, 50, 75 and 100%. Daily DM intake, during starter phase was reduced beyond 25%, but it was not significantly influenced up to 50% during the finisher phase. The final and daily body weight gain, weight of breast, drumstick-thigh, liver and gizzard for the entire experimental period were significantly reduced (P<0.001) beyond 25% replacement of RSM for SBM. In general, replacement of solvent extracted RSM for SBM beyond 25% hampered growth rate, reduced marketable carcass parts and resulted in enlargement of some edible and non-edible carcass offal.

Abstract The worldwide increasing demand for proteins as human nutrition and animal feeding leads to a growing interest on other protein sources. Therefore, rapeseed as an established raw material for the production of edible oils could be a promising alternative protein sources for animals. Mustard seed or rapeseed meals are one of the major protein sources for animals in most parts of the world. The utilization and marketing of these rapeseed meals is very limited due to the presence of anti-nutritional factors in the form of mainly Glucosinolates and erucic acid. But there are still a lot of techniques which reduces the Glucosinolates content to a substantial level and made available as protein source in the diets of livestock and poultry. Therefore, the purpose of this review paper is to identify the limitations and explore the opportunities of using rape seed meal/cake in livestock and poultry diets and propose a recommendation for better use of the resources. The anti-nutritional factors in rapeseed can be reduced by a number of techniques including physical, chemical, biological and crop breeding. But their efficacy varies from one treatment method to the other. Amongst these, crop breeding is the most effective one which is followed by solvent extraction of oil which does not affect the nutritional composition of the feed. Ruminant animals are less susceptible to glucosinolates and other anti-nutritional factors than mono gastric animals. Conventional rapeseed meal can be included up to 10-15% in broiler diets and 7-8 % in layers diets and can replace up to 50% of the soybean meal. But canola seeds can be used up to 20% in compound feed formulation and replacing 25-30% of the dietary soybean meal in layers ration without significantly affecting laying performance. This low glucosinolate rapeseed meal can be used freely as soybean meal in the diets of ruminants and up to 20% in broiler diets and 15 in finishing pigs diets. But for better use of these products, further research on development of varieties, treatment methods, economics of feeding, further investigation on amino acid composition and digestibility of different varieties are very important and introduction and evaluation of canola varaties is required.

Effect of Graded Levels of Slaughter House Residues on Growth Performance and Haematological Parameters in Broiler Chicken's Ration2018 •
This study was aimed to investigate the effect of graded levels of slaughterhouse residue (SHR) on performance and haematological parameters of broiler chickens over the period of 35 days. One hundred day-old chicks were fed diets containing SHR at 0 (control), 5, 10 and 15% dietary levels represented as T1, T2, T3 and T4, respectively. Diets were fed to experimental birds in a completely randomized design (CRD). Each treatment was replicated five times consisting 5 birds Original Research Article
This study was planned to determine the effect of normal protein/normal energy diet of adult Japanese quail (G1) compared with a low protein/low energy diet (G2), on some laying performances, egg quality, some reproductive performance traits, tibia ash contents, and some serum biochemical parameters. Each group was divided into 3 replicates 10 quails each, with sex ratio 1:4. The 2 diets were formulated to have the same calorie/protein ratio (145). The G1 of (20% CP and 2,900 kcal/kg diet, the second cost-effective diet G2 was 18% CP and 2,610 kcal/kg diet. The experimental period lasted 12 wk. The t-test was used to compare the values of means between the 2 groups (P < 0.05) and results indicated that dietary manipulation of G2 did not significantly (P < 0.05) differ from G1 in body weight change, daily feed intake, daily protein intake, egg production, egg weight, feed efficiency, mortality, egg shell thickness, egg albumen index, egg yolk index. Hatchability and fertility was significantly (P < 0.05) in G2 than G1, there were nonstatistical differences in hatched chick weight between G1 and G2. It was concluded that, dietary manipulation and using of 2%-low protein/low energy diets (with normal calorie/protein ratio-145) for laying Japanese quail may not affect the production.
