As well as cereal straw, the use of maize straw in ruminant feeding has been increasing as the feed shortage widens. In addition, cultivation of buckwheat with high straw yield potential is becoming widespread. Thus, performance of 15 female Karya yearlings fed with ration containing wheat, maize or buckwheat straws were compared. The yearlings fed either containing wheat, maize or buckwheat straws in three total mixed rations (30% straw in dry matter) that were consisted of, maize silage, concentrate and cracked maize, formulated to provide 150 g daily live weight gain for 21 d. Total mixed rations was prepared based on the nutritive value of wheat straw. Prior to feeding trial yearlings were acclimatized to their respective feed for a period of 14 d. Straws were included in total mixed rations following the chopping at 1-2 cm. Daily live weight gain and dry matter intake of yearlings fed with mixed ration containing wheat, maize or buckwheat straw were 88, 85 and 135 g/d (P=0.10) and 954, 931 and 1078 g/d (P=0.09), respectively. However, crude protein intake of yearlings (g/d) fed with the ration containing buckwheat straw 14% higher than yearlings fed with the ration containing wheat or maize straw. It was concluded that performance of yearling fed with ration containing buckwheat straws was superior to performance of yearlings fed with ration containing wheat and maize straw, while performance of yearling fed with ration containing wheat or maize straw was similar.

This study was carried out to reveal the present status of goat farms in Nigde, to detect basic priority problems and to offer some solutions to these problems. For this purpose, a survey was conducted to the goat breeders face to face in randomly selected total 38 goat farms.The survey questions; goat farms and growing core business activities of enterprises that reveals the overall structure, and also the level of satisfaction with the priority issues of breeders are designed to measure. Analyze the results was shown that a large portion of goat breeders (85.0%) were primary school graduates, 5.3%secondery school and also 5.3% high school graduates, goat farms have whole hair goat breed. Goat enterprises have rate of 44.7%, more than 500 goat, 92.1% of goat enterprises go out to highlands, also provided 73.7% of the shepherd's family. In addition, operating revenues were determined come from 50% of goat's milk. Goat breeders were evaluated only 39.5% the form of cheese production, as 60.5% of the cheese, butter, yogurt, and the sale of raw milk of the total milk yield. All business was assessed that owners a profitable goat farming as an occupation and the first five main problems were member alliance, ownership sufficient technical knowledge, serving the technical staff, buck mating and breeding presses, goat shelter, respectively. In addition, it was seen that according to Likert scale, at least the first five issues were satisfied that such as feed, labor, and electricity inputs, product marketing price, sold animals the price, market opportunities related to the sale of manufactured products and finacial supply, respectively. As a result, it could be said that the most important problem for goat enterprises in Nigde province is high production costs and low product prices.

This study was carried out to determine the influence of diets including different levels of protein and supplemented with probiotic-enzyme mixed on performance parameters and eggshell quality in laying quails. Japanese quails (n=120), 10 wk of age, were divided into 6 dietary treatment groups and the experiment lasted for 10 weeks. In each experiment group there were 5 replicates, and in each replicates there were 4 birds. Six diets, arranged a factorial design with three protein levels (16, 18 and 20 (control) %) and two levels of supplemented probiotic-enzyme mixed (0.0 and 1.0 g/kg) were used. Dietary crude protein levels and supplementation of probiotic-enzyme did not effect on the body weight gain, egg mass, feed intake, feed conversion, cracked egg yield, specific gravity and shell strength. However, egg production, eggshell thickness and eggshell weight were significantly increased by the addition of probiotic-enzymes mixed. Egg weight in group containing 18% crude protein was significantly higher than the containing 16% crude protein group. Results of the present study indicated that laying quails should be fed 18% crude protein and 1.0 g/kg of supplemental probiotic-enzyme mixed improved egg production and eggshell quality.

In this study, the effect of the lactation sequence and the calving season, which are one of the factors influencing the milk yield in Holstein Friesian breed cows, were studied with meta-analysis method. Meta-analysis is a statistical technique that allows a re-evaluation of the studies conducted by other researchers for the same purpose by bringing them together. Meta-analysis combines and summarizes the results of the studies conducted on various fields, and contributes in making a common judgment among researchers. For these reasons, the studies of 7 different researchers that have been made in this field were brought together and it was aimed to create a common view about the studied parameters. In addition, the heterogeneity in this study was investigated by Chi-Square and I2 test statistics, and these values were found as ×^2=50.205 and I2= 88%, respectively. Therefore, for combining the studies, the fixed effect model wasn’t used in meta-analysis. In this study, the results of the researchers’ studies’ regarding the subject in question were scanned with meta-analytical screening method, and were combined by using the odds ratio (OR) which is the effect size criterion in meta-analysis. As a result of the meta-analysis, the Odds ratio value was found as 0.759 and the effect level was determined middle. With this study conducted, as a result of this meta-analysis conducted, it was found that the contribution done by the lactation sequence on 305-day lactation milk yield in Holstein Friesian cattles in obtaining high milk yield was 0.759 times more compared to the calving season.
