2017
Sema Satık | Mevlüt günal
The aim of this study was to investigate the effect of kefir as a probiotic on the performance and health status of calves. Thirty Holstein female calves with 3-day-old were randomly allocated to three treatment groups: Control (without any probiotic), probiotic (a commercial probiotic mixture-3 g/d/calf bacteria-based and 2 g/d/calf yeast-based) and kefir (20 ml/d/calf). The calves were weaned at 56 days of age. The experiment was performed in 70 days. Treatment had no effect (P>0.05) on weaning and final body weight and starter intake. Although differences in weight gain were not significant (P>0.05), there were trend to increase by probiotic treatments during 0-14 days. Probiotic treatments tended to have a positive effect on the population of the fecal lactic acid bacteria at 14 days. The results of the study indicated that kefir as a natural probiotic in calf nutrition may be beneficial during the first weeks of life.

The purpose of this study is to investigate the environmental factors on the milking time milk yield of Red Holstein cows. For this aim, 172,826 morning milk yield (MMY) and 172,771 evening milk yield (EMY) data collected between 2001 and 2010 from a dairy farm in Aydin Province, Turkey were used. The THI is over 72 from June to August in the region. The effects of calving month, calving year, parity, lactation month and milking month on MMY and EMY were found to be statistically significant. For every month, year and parity, the MMY means were higher than those of the EMY. The peak daily milk yield was determined on the 46th day of lactation (31.7±0.013 kg). For parity, the highest milk yield means were detected for the third parity: 13.69±0.023 kg for MMY and 11.70±0.021 kg for EMY. In conclusion, taking precautions to protect the cows from heat stress especially for the cows calved in summer and keeping the milking interval equal for whole year would help increasing the milk yield.

Plants have developed mechanical and chemical defense strategies that are effective against herbivores. Plants contain chemicals that are known as secondary metabolites (allelochemical) and these chemicals do not directly involve in organisms’ reproduction and growth, on the other hand, they affect survival, growth and behavior of species. These compounds usually take ecological tasks and plants use these compounds against diseases, parasites, and predators for interspecies competition. It is known through the observations on feeding of herbivorous insects that these compounds act as deterrent chemicals or they are toxic against them. Feeding is one of the most fundamental and the most important behaviors for herbivorous insects. Even though host plant preference of herbivores is partially depend on nutrients, this behavior greatly depends on secondary chemistry of plants. Effects of secondary compounds on herbivorous insects can be positive or negative.

In this study, it was aimed to determine the approaches of primary school students’ parents participating in the school milk programme in the Isparta province. The data obtained by the questionnaire method were used from 359 students’ parents who were included in the school milk programme. The families were divided into four groups according to the household income. It was determined that the families consumed more pasteurized milk. The average age of the interviewed individuals was 37.14 years. About 36.21% of the parents were high school graduates. 53.48% of them spend money on milk less than 50 TL. Household size was 4.05 persons. 21.84% of them consume milk hot. The attitude of the parents to the school milk programme was generally positive (82.17%). The school milk programme was believed to be a habit of consuming milk. It was found that 33.33% of the surveyed parents were negative about the school milk programme because they did not trust the content of the milk distributed. In the study, 49.30% of the parents thought that the school milk programme increased the milk consumption habits of the children and 67.97% thought that there was not more supply of milk distributed. For the purpose of implementing the school milk programme, 48.75% of the families had a judge to love the milk and make milk drinking habit. The majority of the families (62.40%) were preferred daily milk in the products distributed and 44% believed that drinking milk was subjected to nutritional analysis. It is suggested that the Ministry of National Education and the Ministry of Health should inform families about the benefits of milk and school milk programme.

Syp, Alina
Agriculture is the second, after energy sector, emitter of greenhouse gasses (GHG), of which increased concentrations in the atmosphere are caused by human activities. In order to reduce GHG, parties ratifying the Kioto protocol have committed to prepare annual emission reports and pledged to reduce emissions. The aim of the study was to analyse changes of agricultural emissions in the World, the European Union (EU) and Poland in 1990-2014. The research uses the United Nations Food and Agricultural database (FAOSTAT), United Nations Framework Convention on Climate Chang (UNFCCC) and World Resources Institute (CAIT) databases. The analysis shows that in the World, in the examined period the total GHG emissions increased by 85%, whereas in agriculture by 15%. However, the EU as a member of Annex I parties had reduced total and agricultural emissions by 24% and 23%, respectively. The reduction of emissions was the result of the implementation of pro-environmental regulations. / Synopsis. Rolnictwo jest drugim po sektorze energii emitentem gazów cieplarnianych (GHG), których stężenie w atmosferze wzrasta w wyniku działalności człowieka. W celu ograniczenia emisji GHG kraje ratyfikujące porozumienie z Kioto zobowiązały się do sporządzania rocznych raportów emisji oraz do ich redukcji. Celem badań była analiza zmian wielkości emisji z rolnictwa na świecie, w Unii Europejskiej (UE) i Polsce w latach 1990-2014. W badaniach wykorzystano bazę danych Organizacji Narodów Zjednoczonych do Spraw Wyżywienia i Rolnictwa (FAOSTAT), Ramowej Konwencji Narodów Zjednoczonych w sprawie zmian klimatu (UNFCCC) oraz Światowego Instytutu Zasobów (CAIT). Z przeprowadzonej analizy wynika, że w badanym okresie na świecie nastąpił wzrost emisji GHG ogółem o 85%, a w rolnictwie o 15%. Jednakże UE należąca do grupy krajów rozwiniętych tj. Aneksu I obniżyła emisje ogółem i z rolnictwa odpowiednio o 24 i 23%. Redukcja emisji była efektem wdrażania pro środowiskowych regulacji prawnych.

There are small number of tables that show digestibility and energy contents of compound feeds produced by feed factory in different regions of Turkey. Thus, in this paper, four different compound feed types (dairy cattle, beef cattle, calf and lamb growing feeds), totalling 78 compound feeds were analysed to determine their feeding value, dry matter (DM), organic matter (OM) digestibility and energy content (digestible energy (DE), metabolisable energy (ME) and net energy for lactation (NEL). As a result of this study, the crude fiber (CF) levels were higher than standard values in calf and lamb compound feeds and beef cattle compound feeds; however, in the dairy cattle and calf and lamb compound feeds, the crude protein (CP) values were lower than standard values. These findings are considered highly important for the region’s animal feeding. According to our results, the compound feeds for dairy cattle and lamb being used for ruminant nutrition in Diyarbakir Province of Turkey were found to have low nutrient qualities; however, in the calf feed both the metabolisable energy level and nutrient quantities were low.

The difficulty of sex determination in most poultry species causes significant financial losses for poultry production as birds cannot be separated at early stages of growth for meat or egg production. Therefore it is important to determine bird’s sex with zoometric parameters. This study was carried out to determine the sex of Japanese quails with zoometric measurements, such as live weight, body length, chest depth and chest width. Eighty-eight male and female Japanese quail chicks were used individually for live weight, chest depth (mm), chest width (mm) and body length (mm) with using digital scaled balance and caliper for every week over a period of six weeks. The weekly collected data were applied to t test for estimating the sex discrimination. The Pearson’s correlation was applied for examining the interrelationship between sex and biometric traits. The results indicated that there was a significant positive correlation between live weight and body length beginning with the 2nd week. Therefore, zoometric measurement of these body traits is suitable for discriminating the sex of Japanese quails in early phase of life.

Water which has become commodity product which is an important product today. Turkey is not a water rich country. In this study, agricultural enterprises in the field of Irrigation Project in Dinar Karakuyu which was implemented in 1992 by DSI. The study analysed which factors affect the willingness to pay additional irrigation water rate with the help of logit model and the irrigation knowledge of farmers was determined by Likert scale. Dinar Karakuyu irrigation network has begun to lose the function in the region. It was supposed 100% irrigation rate but decreased by approximately 9% today. In this context, DSI (General Directorate of State Hydraulic Works) plans to rehabilitation work in the same area. The main material of this study was data obtained from 67 agricultural enterprises through a survey covered by the Irrigation Rehabilitation Project in the province of Afyonkarahisar Karakuyu Dinar. The data was gathered with the help of questionnaires which were answered by farmers in Karakuyu Dinar region. The results indicated that 74.6% of farmers were willingness to pay additional water charge. The data were statistically analysed with the use of the logit model. The model results show that agricultural income, farmers’ educational level, computer ownership, attendance of agricultural training activities, family size and agricultural experience were positive factors affect farmers’ willingness to pay additional water fee.

Grochowska, Renata | Ambroziak, Adam A.
Tendencies in national actions against foreign products currently observed in the European Union indicate protectionism or at least discrimination. The aim of this article is describe economic mechanisms of applying selected import-related policy instruments of Member States and to identify some potential directions of their impact on the functioning of the EU agri-food internal market. The presented mechanisms are related to three situations: (a) hindering the market entry through retargeting of consumer demand; (b) promotion of own products contrary to the fair rules of competition; (c) limiting economic activity of foreign companies. The analyses carried out allowed to identify economic activity areas, where negative effects could reveal and to state that the potential result of these activities may be selective reduction of trade or change of its directions.
