Using a Multi‐Attribute Decision‐Making Method to Evaluate the Effect of in Ovo Injection of Valine and Tryptophan on the Growth Performance of Broiler Chickens [PDF]
He multiple‐attribute method aids management decisions in in ovo nutrition. In ovo amino acid administration reduces embryo mortality risk late in incubation. In ovo injection of 0.55% L‐tryptophan on day 14 improves broiler growth. In ovo 0.55% L‐tryptophan significantly influenced growth metrics at 21 days.

On‐farm study of walking ability in conventional broilers and those labelled as being higher welfare [PDF]
Abstract Background Multiple factors, including genetics and management practices, are known to influence the walking ability of broilers. This field survey aimed to assess the walking ability of broilers in two different production systems. Methods Thirty flocks of conventional (Ross 308) and 26 flocks of welfare‐labelled (Level 1; Ranger Gold/Rustic ...

Sex Detection in the Early Stage of Fertilized Chicken Eggs via Image Recognition [PDF]
Culling newly hatched male chicks in industrial hatcheries poses a serious ethical problem. Both laying and broiler breeders need males, but it is a problem because they are produced more than needed. Being able to determine the sex of chicks in the egg at the beginning or early stage of incubation can eliminate ethical problems as well as many ...

Response of modern broiler chickens to dietary calcium and phosphorus levels below recommendations
This study was carried out to investigate the effects of reduced dietary calcium (Ca) and non-phytate-phosphorus (NPP) levels on performance, carcase yield and bone mineralisation of modern broilers. 11,200 one-day-old chicks (Ross-308) were divided into

The effect of using fruit peel on broiler growth and health [PDF]
To ensure the long-term viability of broiler farming, producers must address a number of issues, including rising feed costs, a ban on antibiotic growth promoters, and growing consumer awareness of chemical residues in broiler chicken meat. Fruit peel is

Meta-analysis of commercial-scale trials as a means to improve decision-making processes in the poultry industry: a phytogenic feed additive case study [PDF]
Background and Objective: In the current study, we sought to determine the value of a meta-analysis to improve decision-making processes related to nutrition in the poultry industry. To this end, nine commercial size experiments were conducted to test the effect of a phytogenic feed additive and three approaches were applied to the data.
