This study investigated the effects of dietary probiotics (Lactobacillus reuteri E81 [LRE], Lactobacillus rhamnosus GG [LRG]), yeast (Saccharomyces cerevisiae S81 [SCS]), and their combined supplementation on fattening performance (BW, DWG, FI, and FCR), meat quality, and rumen and duodenum histology in lambs. The study material comprised ninety 2.5-month-old Anatolian Merino lambs, and the trial was conducted for 70 days. Nine trial groups, each composed of 10 animals, were established. This study demonstrated that, when compared to the control group, the best fattening performance was achieved in the lambs that received 600 ppm of dietary LRE. Neither visceral organ weights nor rumen and duodenum histology was affected in the groups that received the tested feed supplements. Of the meat colour parameters investigated, the L* value was observed to have increased in the groups that were given feed supplements, excluding Groups LRE-600 and SCS-300. It was determined that the probiotic supplements had no effect on the a* and b* colour parameters, but affected the meat pH value. In conclusion, the assessment of the effects of different doses of dietary probiotics, yeast, and probiotic-yeast combinations on performance parameters, visceral organ weights, and meat quality in Anatolian Merino lambs showed that the best results were achieved in the group that received 600 ppm of LRE alone.

İncele - MakaleAçık Erişim2020Scopus SJRQ3The impact of dietary tarragon (Artemisia dracunculus) on serum apelin, brain-derived neurotrophic factor, cardiac troponin concentrations and histopathology of liver tissue in laying hens housed at different stocking densities

Due to its association with several other stress factors (poultry house gases, inadequate ventilation, heat, cold and poor hygiene), the high stocking density is a major stress factor that adversely affects the health and performance of poultry and the quality of the poultry products. Therefore, this experimental study was aimed at analysing the impact of different doses of dietary tarragon (Artemisia dracunculus) on the serum apelin, plasma brain-derived neurotrophic factor (p-BDNF), and cardiac troponin I (cTnI) concentrations, and the correlation between these indicators in laying hens housed at different stocking densities. The aim of this study is to investigate the effects of adding tarragon in different ratios to laying hen rations in the 2ndovulation period on the cTnI, apelin, and BDNF hormone concentrations and the liver histopathology. The experiment was carried out over a period of eight weeks, with 192 Lohman Brown commercial hybrids at 50 weeks of age. Eight groups (four replicates each), composed of laying hens of equal body weight, which were housed at stocking densities of 580 cm2/hen and 810 cm2/hen and received 0, 1, 5 and 10 mmol/kg of tarragon (Artemisia dracunculus) in the feed, were established. At the end of the trial, 96 of the housed egg-laying hens (3 birds in each subgroup, a total of 12 birds in each group) were randomly selected and blood samples were taken from the vena subcutanea ulnaris. The samples collected were analysed for the apelin, p-BDNF, and cTnI contents. The analysis results demonstrated that tarragon supplementation had no effect on the serum apelin, p-BDNF and cTnI concentrations (P > 0.05). The Sub-Groups ST1, ST1.2, and ST6 presented with severe hyperaemia of the sinusoidal, portal and acinar blood vessels, whilst the hyperaemia of these blood vessels was moderate in Sub-Group ST12. Apelin, BDNF, and cTnI can act as protective factors against negative consequences of stress (e.g., stocking density or heat stress).

The aim of this trial was to study the effects of consuming water with apple cider vinegar (ACV) and feed including mushroom (Agaricus bisporus) stalk (MS) on performance and certain egg characteristics. The hens were separated into four treatment groups (with 4 replicates and 6 hens per replicate). The experimental groups were control (not consumed ACV and MS), ACV (3 ml/l drinking water), MS (20 g/kg feed) and ACV+MS (combination). At the end of the experiment, among the performance criteria tested, body weight, feed intake, egg production and weight of eggs, and feed efficiency were not affected by the treatments (P>0.05). Treatments had no effect on physical external and internal egg characteristics. The amount of yolk malondialdehyde of the ACV and MS groups was lower than the control group (P<0.05) in stored eggs (28 d) (P<0.05).

Organik olarak üretilen tavuk yumurtasının daha fazla besleyicilik ve duyusal özelliklere sahip olmasının yanı sıra sağlığa zararlı herhangi bir madde içermemesi, tüketicinin öncelikli beklentilerindendir. Araştırmalar, beklenenin aksine; kafes yumurtaları ile organik yumurtaların kuru madde, lipit ve yağ asitleri arasında önemli bir farklılık bulunmadığını göstermektedir. Organik yumurtanın kafes yumurtasına göre yaklaşık iki kat fiyata satılmasının sadece psikolojik ve etik motivasyon taşıdığı bildirilmektedir. Avrupa Birliği Konseyi organik yumurta üretiminde tavukların bazal rasyonun yanı sıra yeşil kaba yem materyallerine erişimini de gerekli görmektedir. Ancak bu erişimin sağlanması durumunda, organik olarak üretilen yumurta tüketici beklentilerine karşılık verebilir. Araştırmalar ülkemiz Organik Tarım Kanuna göre tavuk başına ayrılan 4 m2 'lik gezinti alanının bu talepleri karşılamada yeterli olmadığını göstermektedir. Bu durum tavuklara ayrılan gezinti alanının çeşitli yem bitkileri ile rotasyona uygun olarak ekili olmasını sağlayacak şekilde artırılmasını veya gezinti alanına dışarıdan ilave yeşil kaba yem materyallerinin getirilmesini zorunlu kılmaktadır. Böylece fonksiyonel gıda özelliği olan bir ürün elde etmenin yanı sıra gagalama ve kanibalizmin azalarak hayvan refahının arttığı bir üretim tarzına ulaşılmış olacaktır. Bu derlemede organik yumurta üretiminde başta karotenoidler olmak üzere yağ asitleri gibi kimyasal içeriklerin artırılması ile renk, koku ve tat gibi duyusal özelliklerin iyileştirilme olanaklarına yönelik uygulamalara yer verilmiştir.
