Factors affecting meat quality in farm animals

Meat has been one of the most basic nutrients since the first day of humanity. As food, meat is expressed as the muscle and fat found between the bones and skin of animals. It has an important place in human nutrition due to the protein (amino acids), fatty acids, minerals (iron and zinc) and vitamins (especially B12) it contains. Thanks to these nutrients, vital activities such as growth and development of individuals, regeneration of cells, repair and growth of tissues, formation of vital fluid blood, functioning of body systems, development of immunity and reproduction are ensured. As with other animal products, there are factors such as species, breed, feeding, environmental temperature, stress or processing that affect meat yield and quality in farm animals. In the current study, similar biotic and abiotic factors affecting the meat quality of farm animals are discussed

The effects on feed performance and carcass features of chick quality and pre- starter feed application in broiler chicks

In the study, it was aimed to determine the qualitative parameters which are used to classify the chick’s quality after hatching and to investigate the effects on the fattening performance during 35-42 day fattening period. In the experiment, one day old 400 chicks (200 male and 200 female) were allocated into two groups (one control+one treatment), each group had five subgroups with 40 chicks (20 male+20 female) At the beginning of the experiment, a sex discrimination was made on chicks and then divided into two different (high and low quality) groups. While the gender and quality classified chicks were being grouped, the groups were formed as the live weights were closer to eachother in order to eliminate the diffreneces depending upon the initial body weights. The chicks were fed with 3 different diets to meet the nutrient requirements that vary according to their period. The chicks were kept total 5 weeks in trial, feed and water were given as ad libitum. The chicks were weighted weekly to calculate body weight gain, feed conversion rate and feed intake. The results obtained from this study showed that, the differences of initial body weights between the groups were statistically significant (P0.05). The differences in the feed conversion rates between the groups at the 4th week were statistically significant(P<0.05). According to the data of hot carcass weight,cold carcass weight, abdominal fat weight, carcass yield and abdominal fat ratio after the slaughter, the difference between groups in male gender is not statistically significant but ın female gender, only abdominal fat ratio was statistically significant among the groups (P<0.05).We are grateful to the Çukurova University Scientific Research Projects Unit for their financial support to this project (Proje No: FLY-2018-9946)

THE EFFECTS ON FEED PERFORMANCE AND CARCASS FEATURES OF CHICK QUALITY AND PRE-STARTER FEED APPLICATION IN BROILER CHICKS

With the increase of the population, it has become inevitable to increase the production of poultry meat and to increase the quality of poultry meat production in order to meet the increasing demand for animal food and to ensure that people are fed on a balanced basis. There are many factors affecting the economy, quantity and quality in poultry meat production (genetic factors, herd age, hatching egg quality, egg collection time, egg storage, hatching temperature, chick quality etc.). These factors include a long period of time from the feeding of breeding animals to the cutting of chickens. Depending on the effects of all these factors, chicks are produced in different qualities. Among these factors, chick quality is the most essential for high efficiency as it is a combination of all other parameters. Because the quality of daily chicks is very important for a good start and cutting performance in production (Meijerhof, 2009). The present study was conducted to determine parameters to be used in chicks quality classification after incubation and investigate the effects of pre-starter feeding in the first five days on fattening period lasting 35-40 days for chicks classified low and high quality.This study was supported by Çukurova University Scientific Research Projects Unit (Project Number: FLY-2018-9946)

Microbiological and Nutrient Analysis of Spiriluna platensis Produced in Poultry Manure Enriched Medium

Spirulina platensis is an interesting source of important protein for both human and animal consumption, which is cyanobacteria, is a crucial functional food additive. Spirulina platensis which is a photosynthetic micro algae, contains high crude protein content (62-70%) as well as precious metabolites (Fox, 1996). Recent studies have propound that dry chicken manure can be used as low-cost nitrogen source in cultivation of Spirulina platensis (Ungsethaphand at al., 2007). Dry chicken manure(DCM) contains most of elements particularly nitrogen (N) and phosphorus (P) which microalg need for growth and flourish. In Turkey, about 7 million tons of poultry manure creates environmental problems per year(Eleroğlu at al., 2013). The aim of study, cell density was counted and dry biomass were analyzed (DCM medium) was to compare the microbiological quality of Spirulina platensis cultured in standart medium and DCM medium.Çukurova University Scientific Research Project Commission (Project Number: CUBAP-09/2017-9767)
