Three trials were conducted comparing hatch weight as a percentage of egg weight with feed conversion of five selected lines (selected for low or high feed conversion) within two populations (broiler and randombred) of chickens. In each trial all eggs were weighed and divided into groups of 1...
In a first trial glycerol was tested as a feed ingredient for broiler chickens. The influence of glycerol supplementation on weight gain, feed intake, feed conversion ratio and N‐balance was proved. 90 Broiler chickens (Lohmann Meat) were fed ad libitum in 6 groups with nearly isoenergetic ...
The sad truth is that the feed conversion rate for chickens raised by nearly all backyard hobbyists is two, three, or even four times as high as the ratio for industrial chickens. Yes, you do end up with a higher quality chicken that lived a happier life if you raise it yourself, but...
[46] reported an effect of Lactobacillus on growth and fat deposition in broiler chickens. Some genera of the family Lactobacillaceae were involved in the production of antimicrobial bacteriocins, which are related to gut microbiome composition [47]. A species of the genus Lactobacillus with the ...
The aim of the present study was to investigate the effect of exogenous in ovo ghrelin on hatching weight, post-hatching performance (feed intake, weight gain, and feed conversion ratio), and carcass characteristics of broiler chickens. Show abstract Neuropeptide Y, peptide YY and aluminum in ...
In this study the starch digestion rates in broiler chickens from 18 samples of 5 commonly used feed grains (sorghum, wheat, maize, barley, triticale) were determined. The methodology to determine starch digestion rates in
Effect of particle size and enzyme supplementation of diets based on dehulled peas on the nutritive value for broiler chickens The effect of diets based on dehulled peas on live weights, cumulative feed intake, feed conve...
An understanding of possible microbiota drivers of these differences has potentially important benefits for industry. In this study, differences in cecal and jejunal microbiota between broiler chickens with extreme feed conversion capabilities were analysed in order to identify candidate bacteria that may ...
The effect of hatch time and the timing of access to feed on growth rate and breast muscle development was assessed in Ross 308 broiler chickens. Chicks were removed from the incubator upon hatching, and classified as early (EH), midterm (MH), or late (LH) hatchers, based on the duratio...
