2016
Kasım Özek
The efficiency of chelated forms of trace minerals in poultry nutrition and the trace minerals requirements of poultry were discussed in this review. Trace minerals are essential for all farm animals, and these minerals, individually or together with other mineral, take part in many events such as metabolic activities, development and repair of different tissues, growth, immune and reproductive systems. In the last years, lots of studies related to different organic forms of trace minerals on the effects of broiler and laying hens were carried out. The results of these studies have showed that organic trace minerals added to poultry diets at lower levels than inorganic trace minerals are more efficient than inorganic trace minerals and they provide some advantages in poultry nutrition. One of the most important advantages is the reduction of mineral amount excreted in faces. In addition, the results of researches conducted especially in the last few years have shown that the chelated forms of trace minerals strengthen the poultry immune system, and increase the use of other nutrients. However, there are inconsistent between the effects of different forms of trace minerals used in poultry diets on the performance.

Ali Bekret | Soner Çankaya | Sibel Silici
This study during the spring of 2014, effects of plant extract and oil mixture obtained from various plants added to the syrup given to the forces equalized bee on physiological characteristics of the colonies were examined. Bee colonies (10 colonies in each group) were randomly divided into two groups. When the first group feed syrup and plant extract oil mixture, at the same rate with feed syrup only test group to control group (1/1 sucrose-water) was applied. According to the research results, the plant extract-oil mixture was not effective on the number of frames and hive weight. The mixture although numerically increased the amount of brood rearing area, this effect was not statistically significant. However, provided statistically significant increase in honey production. We concluded that, while the plant extract-oil mixture tested is not effective in brood production, is effective on honey production.

2023
Serpil Gençoğlan
Sıcak bölgelerde ve yaz aylarındaki yüksek sıcaklıklar, yumurta tavuklarının verim ve üretkenliğini bozmaktadır. Bu çalışmada, sıcaklık stresinin yumurta tavuklarının verim ve üretkenlik üzerine etkilerine dikkat çekerek ortaya çıkan kayıpları azaltmak için alınacak önlemler hakkında detaylı bilgi vermek amaçlanmıştır. Sıcaklık stresi, bağışıklık tepkilerini engellenmesi nedeniyle yüksek ölüm oranları ile ticari yumurta tavuğu üretiminde önemli ekonomik kayıplara yol açan ve üretim performansının tüm parametrelerini, üretkenliği etkileyen en zorlu sorunlardan biridir. Yüksek vücut ısısı, sıcak-kuru deri, felç, baş ağrısı ve bilinç kaybı gibi nörolojik belirtilerle kendini gösterir. Sıcak krampları ve çarpması sonucu ölümlere sebep olmaktadır. Ayrıca sıcaklık stresi dişi-erkek yumurta tavuklarının üreme hormonlarının durumunu da bozar. Erkeklerde canlı sperm sayısı ve hareketini azaltarak kısırlığa neden olur. Sıcaklık stresinin etkisi yaşa, cinse, vücut ağırlığına, bağıl neme ve yüksek sıcaklıkta kalış süresine bağlıdır. Sıcaklık, optimum yumurta verimi ve kalitesi için 24°C’nin, refah ve üretkenlik için ise 27°C’nin üstüne çıkmamalıdır. Bu sıcaklığın üstünde tavuklarda hızlı nefes alma, vücutlarından çevreye ısı yaymama problemi, yem tüketimi ve canlı ağırlık artışında azalma görülmeye başlar. Yüksek sıcaklıklarda 34-35°C yumurta üretimi yaklaşık %30, yem alımı da %30-50 arasında azalmaktadır. Sonuç olarak, sıcaklık stresine karşı yem yönetimi, sıcaklık stresi azaltıcı katkı maddelerinin yeme ve suya eklenmesi, barınaklarda iklimsel çevre denetimi, erken yaşam şartlandırması ve sıcaklık stresine dayanıklı ırkların genetik seçimi gibi önlemler alınabilir.

Suat Dikel | Ilgın Özşahinoğlu | Mustafa Öz | İbrahim Demirkale
In the study, the growth performances of the Shibot fish (Tor grypus) with an average weight of 2.38 g were evaluated by feeding them with 3 different protein-containing feeds for 45 days. In order to create these evaluations, the experimental groups were designed as G1 (33%), G2 (37%) and G3 (41%) fed with different protein levels. Effects on body weight gain (BWG), Feed conversion rate (FCR), Specific growth rate (SGR), Survival rate, Economic conversion rate (ECR) and Economic profit index (EPI) as growth parameters has been researched. At the end of the study, the offspring reached a weight of 3.42±0.16 g, 4.17±0.06 g and 4.50±0.02 g, respectively. G3 and G2 group individuals showed similar performance in terms of end-trial FCR, EPI and ECR.

Sibel Alapala Demirhan | Murat Erdem
In the present study, it is aimed to determine the current state of the goat raising businesses operating in the city of Uşak and in its provinces, their problems and to come up with suggestions for solutions to these problems. In the current study, as the sampling of the study, 132 goat-raising businesses were selected by means of stratified random sampling method and they were administered a questionnaire consisted of 83 questions. The data obtained from the analysis of the questionnaires have revealed that high majority of the goat-raisers are elementary school graduates (86.4%) and they generally raise Hair goat (89.4%). Moreover, it has also been determined that for the mating of goats, male goats are brought into the herd in September and October and this mating process occurs in the form of free insemination, the age for female goats to be used as stock is 15-18 months old, additional feeding and synchronization are not generally practiced and weaning of baby goats occurs when they are 3-4 months old. Births are usually given in February-March and milking also starts in this period and lasts 6 months on average, the lactation milk yield is 60-80 liters, milking is performed once a day with hand and the produced milk is mostly used in cheese production. Moreover, in goat raising, transhumance is not a common practice and high majority of the breeders apply regular protective vaccines. As in many other regions, many problems such as high feed prices, the difficulty in finding a shepherd and price fluctuations force goat breeders to quit. For goat raising to be sustainable, technical and economic supports given to breeders should continue and improve. If the feed can be supplied with the internal resources of the businesses and if their products can be marketed directly without using intermediaries then some of the problems can be alleviated. Putting greater emphasis on this issue and developing incentive policies will make contributions to goat raising. As a result of the present study, it was concluded that developing goat raising businesses operating mostly as small-scale family businesses in the city of Uşak to large-scale businesses where intensive production is made by providing the necessary incentives and subsides is of great importance.

The poultry industry in the developing countries is facing some challenges, one of which is an increase in the cost of feed because of high prices of protein and energy sources. Moringa oleifera is a rich source of protein and crude fiber content. The crude protein (CP) content of Moringa ranges from 7.12 to 39.17%. Negligible content of tannins and other anti-nutritive compounds and offers an alternative source of protein to ruminants and non-ruminants. Although rich in nutrients such as protein and minerals, Moringa oleifera is one of those plants that have not been studied for many years. In addition, they are also faced with the problem of the development of antibiotic resistant pathogens due to unwise and excessive use of antibiotics. In this paper, feeding studies made on the Moringa oleifera used in nutrition of poultry and ruminant species have been reviewed.
