Colostrum is a nutrient-dense fluid secreted by female mammals for the first few days following birth. Colostrum can be supplemented to poultry diets as a feed additive due to its nutritious and performance-enhancing properties. This study was conducted to determine the effect of dietary colostrum powder (CL-P, Alpha Lipid Lifeline Colostrum, New Zealand) on growing performance, carcass weight and yield, organ weights, serum vitamins and malondialdehyde (MDA) levels in quails (Coturnix coturnix japonica). A total of 90 birds, one day old, were divided into 3 groups consisting of 6 replicate cages, 5 birds per cage. Birds were randomly fed on one of three diets: basal diet and basal diet supplemented with 2.5% or 5% of CL-P. At the end of the period of 42 days, CL-P supplementation increased final body weight (P < .0001), weight gain (P < .0001), feed intake (P = .03), feed efficiency (P < .0001), carcass weight (P < .0001) and carcass yield (P < .01). Amounts of serum MDA (P < .001) levels also increased with increasing supplemental CL-P. As a result, growth performance can be improved and serum lipid peroxidation can effectively be attenuated by dietary CL-P supplementation at 5% of diets in Japanese quail.

This study aimed to determine the effects of parenteral selenium (Se) and vitamin E supplementation on economic impact, milk yield, and some reproductive parameters in high-yield dairy cows in the dry period and in those at the beginning of lactation. At the beginning of the dry period, cows (n = 323) were randomly divided into three groups as follows: Treatment 1 (T1), Treatment 2 (T2), and Control (C). Cows in group T1 received this preparation 21 days before calving and on calving day, and cows in group T2 received it only on calving day. The cows in the control group did not receive this preparation. Supplementation with Se increased Se serum levels of cows treated at calving day (p<0.05). Differences in milk yield at all weeks and the electrical conductivity values at the 8th and 12th weeks were significant (p<0.05). Supplementation with Se and Vitamin E decreased the incidence of metritis, the number of services per conception and the service period, but had no effects on the incidence of retained fetal membrane. A partial budgeting analysis indicated that Se supplementation was economically profitable; cows in group T1 averaged 240.6$ per cow, those in group T2 averaged 224.6$ per cow. Supplementation with Se and Vitamin E has been found to increase serum Se levels, milk yield, and has positive effects on udder health by decreasing milk conductivity values and incidence of sub-clinical mastitis.

This experiment was carried out to determine the effect of dietary supplementation of Rosemary (Rosmarinus officinalis) ethanol extract, on performance and blood parameters of broilers. One hundred twenty 1-day-old male Ross-308 broiler chicks were used in this experiment. The chickens were divided into 3 groups, including one control and 2 treatment containing 40 birds each. Each group was divided into four replicates and the study lasted 42 days. Group 1 (Control group) was fed with only basal diets. Group 2 (ROE 100mg/kg) was fed basal diet supplemented with 100 mg/kg R. officinalis L. Group 3 (ROE 200mg/kg), was fed basal diet supplemented with 200 mg/kg R. officinalis L. At the end of experiment blood samples collected. Body weight gain (P<0.01) and feed consumption (P<0.001) were decreased when compared with control group, while feed conversion ratio is not affected. Besides, it is detected that rosemary ethanol extract increases the enzymes antioxidant (SOD, GPx, CAT), GSH; reduces lipid peroxidation (MDA) and reduces the ALT, AST, blood glucose level (P>0.05) and LDL-cholesterol (P<0.01). The results of this study showed that lipid peroxidation, oxidative stress parameters significantly decreased after ROE application. Rosemary (R. officinalis L.) ethanol extract at 200 mg/kg administered group was found to create a more positive effect on some biochemical parameters and can be a viable alternative growth promoter in the feeding of broilers.

Summary:In order to investigate the producer & production characteristics and disease control applications at Turkish dairy herds, an interview survey was carried out in randomly selected 91 dairy herds out of 1684 Turkish Dairy Breeding Association herds in Burdur, Kırklareli and Konya provinces in July 2004. The study depicted that percentages of producers having education level higher than primary school, and not having any job training relate to dairy farming were 21% and 79% respectively. The majority of the producers did not follow innovations (46%) and, was not aware of somatic cell counts and subclinical mastitis (93-97%), and the European Union's regulations related to dairy farming (76%). Amongst the producers interviewed, 13% used antiseptic when cleaning udder and 37% dried udder after washing. The percentage of producers using post milking teat dip, dry cow therapy, vaccination against mastitis, California Mastitis Test (CMT), and regularly keeping records for clinical cases were 18%, 62%, 29%, 15% and 20% respectively. The findings differed amongst the provinces and between the herd sizes. For majority of the questions the differences amongst the provinces were found to be significant at p<0.05. However, the statistical associations between the herd size were not statistically significant at, p<0.05. The study concluded that the producers in general, applied well-known methods for treatment and control of mastitis, but had lack in knowledge related to basic rules of hygiene applications and disease preventions. These problems are likely to have strong links with the level of formal education and job training of the producers. These findings emphasise that improvements in education and job training of the dairy farmers are as important as the efforts to improve farm size during the process of Turkey's integration to the European Union.Key words: Dairy farming, mastitis control, milk hygiene, producers' profiles, production characteristicsTürkiye'de Konya, Burdur ve Kırklareli İl'lerindeki süt sığırcılık işletmelerinde üretici ve üretim özellikleri ile mastitis kontrol uygulamaları Özet: Türkiye'deki süt sığırcılığı işletmelerinde, üretim yapısı, hijyen uygulamaları ve mastitis kontrol faaliyetlerini incelemek amacıyla, Temmuz 2004 tarihinde Burdur, Kırklareli ve Konya illerinde Damızlık Sığır Yetiştiriciliği Merkez Birliği'ne bağlı 91 adet süt sığırcılığı işletmesine anket uygulanmıştır.
