Evaluation of as a Feed Additive in Low-Protein Diets of Broilers.

is a natural antioxidant product that has the ability to improve the performance of poultry. Therefore, the present study aimed to evaluate the effect of using as a feed additive in broiler diets. A total of 252 daily male Ross 308 chicks were randomly assigned to six groups.

Effects of Different Packaging Types and Storage Periods on Physicochemical and Antioxidant Properties of Honeys.

Preserving the nutritional value of honey without compromising its properties until consumption is crucial. However, different types of honey may respond differently to packaging and storage conditions. This study aimed to assess the effects of different packaging materials (tin cans, light-colored glass jars, and dark-colored glass jars) and storage durations (initial, 6 months, and 12 months) on the physicochemical and antioxidant properties of pine, flower, and thyme honey.

Effects of cage type and the light-dark cycle on the behavior of hens subjected to forced molting.

In this study, the effects of cage type and the light-dark cycle on the behavior of hens before, during, and after forced molting were determined. For this purpose, 73-week-old hens were placed in the two different cage types used in the experiment. The barley method was used to induce molting at 75 weeks of age.

Comparison of fattening performance, carcass traits, meat quality, and leg bone traits among three goose genotypes reared under intensive conditions.

This study aimed to evaluate fattening performance, carcass traits, meat quality, and leg bone traits in geese reared under an intensive production system, depending on genotypes. In the study, a total of 210 goslings (70 goslings for each genotype such as Linda, Toulouse, and Mast) were obtained from 168-week-old breeders. The geese were fed ad libitum with the same feeds during 12 weeks.

Effects of abrupt and gradual light/dark switching on growth performance, behavior, villus development, meat characteristics, and immunity of broilers.

The aim of this study is to determine the effect of abrupt and gradual light/dark switching on growth performance, behavior, villus development, meat characteristics, and immunity of broilers. A total of 270 daily male broiler chicks were used in the experiment. The study comprised three groups based on whether the transitions between light and dark periods were abrupt or gradual.

Tibia properties in broilers raised on their own commercial diets with different growth rates and sex during a 10-week rearing period.

Background: Genetic selection applied to broilers results in fast growth and an increase in meat yield. However, this situation causes welfare problems in broilers.

Objectives: The aim of this study is to determine the weekly changes in the tibia characteristics in broilers raised on their own commercial diets.

Carcass, visceral organ, and meat quality properties of two broiler hybrids differing in growth rates.

This study aimed to determine the carcass, visceral organ, and meat properties according to the sex in slow growing broilers (SGB) and fast growing broilers (FGB). Six broilers from each genotype and sex group were slaughtered every week. It was determined that the difference between SGB and FGB in terms of carcass yield occurred at the highest level at 5 weeks and this difference continued until the age of 10 weeks.

The effects of using UV light instead of formaldehyde in disinfection of hatching eggs on shell microbial load, embryo development, hatchability, and chick characteristics.

In this study, it was aimed to determine the effects of using UV light instead of formaldehyde in disinfection of hatching eggs on the microbial load, shell and yolk compositions, embryo development, hatching results and chick characteristics. 552 hatching eggs were divided into formaldehyde fumigation and disinfection with UV groups. After disinfection, bacteriological growth was not observed in groups.

Egg mineral levels, hatching results and bone properties in embryos and chicks obtained from broiler breeders at different ages.

It is inevitable to obtain chicks from breeders of different ages in broiler fattening. However, breeder age has an effect on eggs. There is no detailed study on the changes in mineral levels in eggs and bones of these effects.

Age and sex related changes in fattening performance, dermatitis, intestinal histomorphology, and serum IgG level of slow- and fast-growing broilers under the intensive system.

Due to consumers' concerns about broiler welfare, slow-growing broilers (SGB) have also been used in production. Fast-growing broilers (FGB) reach slaughter weight earlier the slow growing. This study was aimed to determine the sex-related changes in fattening performance, dermatitis, intestinal histomorphology, and serum IgG level of SGB and FGB under the intensive system during the 10 weeks.

Effects of the genotype, cage type and time period on the behaviour of laying hybrids at the same egg production level.

Hybrids with different morphological and yield characteristics are used in the table egg production. There is no change in the cage systems according to the different hybrids in the regulation. This study aimed to investigate the effects of genotype (brown laying hybrids (BLH) and white laying hybrids (WLH)) and cage type (conventional and enriched cages) on behaviours of hens at the 90% egg production level.

Effect of alternative litter materials on the behaviour of male broilers.

The welfare of broilers is strongly dependent on the litter material because they spend their life in contact with it. The purpose of this study was to determine the effects of alternative litter materials on broiler behaviour. Two hundred eighty-eight 1-day old male broiler chicks were used.

Comparison of litter quality, performance, and some welfare parameters of broilers reared on the sepiolite-supplemented paper waste sludge.

Waste management is the protection of the environment and the health of the population. Paper waste sludge is produced during paper production and sepiolite is a natural clay mineral. The aim of the study was to investigate the usability of sepiolite-added paper waste sludge as a bedding material in the broiler production.

Effects of coated hatching eggs obtained from old broiler breeders with chitosan on embryonic growth, hatching results and chick quality.

The aim of this research was to determine the effects of coating broiler hatching eggs with chitosan on egg quality, embryonic growth, hatching results and chick quality. Eggs obtained from old broiler breeder, aged 59 weeks, were used. Eggs were divided into two groups (coated with chitosan and uncoated) groups.
