Journal ArticleDOI
Productive performance and egg quality of brown egg-laying hens in the late phase of production as influenced by level and source of calcium in the diet.
H. M. Safaa,Martina Pérez Serrano,D. G. Valencia,M. Frikha,E. Jiménez-Moreno,Gonzalo Gonzalez Mateos +5 more
TL;DR: It was concluded that Brown egg-laying hens in the late phase of production require more than 3.5% Ca in the diet and that the substitution of 40% of fine LIM with COA or OYS does not affect productive performance and has little impact on shell quality and tibia characteristics.
Journal ArticleDOI
Effects of increasing levels of pea hulls in the diet on productive performance, development of the gastrointestinal tract, and nutrient retention of broilers from one to eighteen days of age
TL;DR: It is concluded that the size of the digestive organs increases with increasing levels of PH in the diet and young broilers have a requirement for a minimum amount of dietary fibre.
Journal ArticleDOI
Effects of the Levels of Methionine, Linoleic Acid, and Added Fat in the Diet on Productive Performance and Egg Quality of Brown Laying Hens in the Late Phase of Production
H. M. Safaa,H. M. Safaa,Martina Pérez Serrano,D. G. Valencia,X. Arbe,E. Jiménez-Moreno,R.P. Lázaro,Gonzalo Gonzalez Mateos +7 more
TL;DR: It is concluded that reducing the level of SFAT from 3.0 to 1.1% might decrease productivity and the percentage of extra large eggs and eggshell quality was not affected by any of the dietary treatments.
Journal ArticleDOI
Effect of main cereal of the diet and particle size of the cereal on productive performance and egg quality of brown egg-laying hens in early phase of production
H. M. Safaa,E. Jiménez-Moreno,D. G. Valencia,M. Frikha,Martina Pérez Serrano,Gonzalo Gonzalez Mateos +5 more
TL;DR: It is concluded that neither type of cereal nor GMD affected productive performance or egg quality of young brown hens, except for feed intake that increased with the coarser particle size.
Journal ArticleDOI
Influence of the main cereal and feed form of the diet on performance and digestive tract traits of brown-egg laying pullets
TL;DR: It is concluded that wheat can be used in substitution of corn in pullet diets with only a slight reduction in BW gain and that feeding pellets from 1 to 45 d of age increasedBW gain and pH of the gizzard and reduced the relative weight of thegizzard and the length of the gastrointestinal tract at 120 d ofAge.
