This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...

This study presents a life cycle assessment (LCA) comparing laying hen to broiler chicken production. Sustainability and protein conversion efficiency are considered. The protein-to-protein was calculated per 1t of feed consumed by birds 1 kg in end products for human consumption. Additionally, part the commercial replaced live black soldier fly larvae, reared on Gainesville diet, fruit vegetab...

For the effective development of poultry farming in Kazakhstan, it is necessary to overcome a number constraining factors, one which insufficient modern safety control system throughout meat production chain. The article develops flowchart semi-finished product process based on meat-broiler with soy flour, examines possible risks (hazards) for management measures products, identifies three crit...

The economics of poultry meat production depends on numerous factors, but most important is general economic policy. For the economic analyses, net profit, gross return, net return, Benefit to Cost Ratio (BCR), productivity, etc. have to be computed. In this study, various Artificial Neural Network (ANN) models were developed to estimate the BCR of broiler farms in tropical regions of Iran. To ...

Sustainable feed formulation (defined here as nutritional and economic feed optimization) is substantial in feed chain production from crop farmers to livestock producers. Diet formulation employing a static linear programming (LP) approach, which is widely used in trading firms and feed production facilities, does not allow for intertemporal flexibility. Our approach allows the interaction bet...

This study aimed to assess the effect of the number of straw bales (SBs) provided on the behaviour and leg health of commercial broiler chickens. Houses containing ~23 000 broiler chickens were assigned to one of two treatments: (1) access to 30 SBs per house, '30SB' or (2) access to 45 SB per house, '45SB'. This equated to bale densities of 1 bale/44 m2 and 1 bale/29 m2 of floor space within h...

Broiler chicken production is widely dispersed across the globe, and one important issue for growers is the selection of adequate bedding material, as the availability and price of substrates varies among countries and regions within a same country. This study aimed at applying a multiple criteria analysis approach for the selection of the most appropriate bedding material for broiler productio...

An experiment was conducted to investigate the effects of environmental temperature and dietary Mn on egg production performance, egg quality, and some plasma biochemical traits of broiler breeders. A completely randomized factorial design involved 2 environmental temperatures (a normal temperature, 21 ± 1°C, and a high temperature, 32 ± 1°C) × 3 dietary Mn treatments (a Mn-unsupplemented corn–...

The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environm...
