Data on birth weight, calving season, calf sex, and calving year were collected from 3168 Brown Swiss calves. The data were exposed to regression tree method, which is a tree-based and a non-parametric method. In this method, birth weight, an important trait in cattle breeding, was a response variable and environmental factors such as calf sex, calving season and year were accepted as explanatory variables. Statistical evaluations were done using SPSS (Exhaustive CHAID) statistical package program. In the present study, birth year was the most significant factor for birth weight (P<0.01), followed by sex (P<0.01) and calving season (P<0.01). The highest average birth weight was recorded for the calves born during the years 1999-2001. The calves born in summer and fall seasons of 2002-2004 years were lighter than those born in winter and spring seasons of same years. Sex of calf influenced birth weight of calves born between the years 1991 and 1995 (P<0.01). Among factors, calving season was a factor that had highly statistical influence on birth weight of the group of calves born between 2002 and 2004 years. As a result, use of regression tree method, which is not influenced by multicollinearity, outlier, and missing values is recommended with the objective to identify factors that can be statistically significant on birth weight of Brown Swiss calves.

Monthly milk yield records representing the test days milk yield of 777 Simmental cows were used to estimatelactation curve parameters by using Wood, Gaines, Parabolic, Hayashi, Dhanno and (second degree) polynomial modelsand to compare the shape of lactation season curves resulted from fitting all of these models. These models were given inexplanation of the parameters and according to the lactation season, the parameters a, b and c for these models at all theperiods were estimated. Secondly, the formula of some criteria, such as time to peak, peak production, turning point timeand turning point production, are presented in mathematical procedure and then t the criteria values are calculated for allof the examined models. Furthermore, partial derivatives of the models according to the parameters were given inmathematical procedure. For the season, winter, spring...

Treatments were 1) alfalfa without any additive (control), 2) alfalfa + OP (70% alfalfa mixed with 30% fresh OP, LAB0), 3) treatment 2 with 1.5 g LAB/ton (LAB1), 4) treatment 2 with 3 g LAB/ton (LAB2) and 5) treatment 2 with 4.5 g LAB/ton (LAB3). Treatments were replicated three times in laboratory mini silos for 90 d in a closed barn with a ambient temperature (15 to 18 o C). As a result of this study, the experimental treatments did not affect on DM of silage at the end of the ensiling period. Control treatment had the highest pH (4.5) among the experimental treatments (P<0.05). Supplementation alfalfa with OP resulted in significant increase in water soluble carbohydrate (WSC) and total volatile fatty acids (VFAs) (P<0.05). Treating alfalfa silage with OP and LAB improved aerobic stabilities of treatments significantly, as compared to LAB0. Supplementation of silage with OP and bacterial inoculant increased DM digestibility. These findings indicated that LAB can improve the aerobic stability and quality of silage in laboratory silos and also, OP and LAB might improve silage quality and cause better silage management in the farm.

Sut verimi uzerine akrabali yetistirmenin etkisini arastirmak icin, diger sistematik cevre faktorlerine gore duzeltilmis veriler iki farkli modelle analiz edilmistir. Birinci modelde, suru akrabali yetisenler ve akraba disi yetisenler olarak iki guruba ayrilmistir. Buna gore akrabali yetisen grup, laktasyon sut verimi bakimindan populasyon ortalamasindan 90 kg, akraba disi yetisen gruba gore ise 79 kg daha az sut vermistir. 305 gunluk sut veriminde ise akrabali yetisen grup populasyon ortalamasindan 55 kg, akraba disi yetisen guruptan ise 110 kg daha az sut vermistir. Ikinci modelde ise akrabali yetistirmenin verimlere etkisi basit dogrusal regresyon katsayilari kullanilarak incelenmistir. Buna gore akrabali yetistirme katsayisinin her %1 artisina karsilik laktasyon sut veriminde 6.14 kg, 305 gunluk sut...

Forty six Turkish Saanen Goat were used in the present investigations . These goats were milked with milking machine twice a day. The traits recorded were: daily milk yield (DMY), udder upper height (UUH), udder width (UW), udder length (UL), udder diameter (UD), teat angle (TA), udder volume (UV), somatic cell count (SCC), lactation length (LL), and lactation milk yield (LMY) , Respectively. In the multiple linear regression analysis, significa nt effects of and LT (P 50 0 among all the goats (Node 2) had the highest LMY (297.357 lt) or Node 4 as a group of the goats with LL > 191 days among the goats with TA < 50 0 provided higher LMY average except for Node 2. If there is a verification at gene...

In the current experiment, lactation period, daily milk yield, lactation milk yield, arithmetic somatic cell count (SCC), geometric SCC, Log10 SCC, udder upper height, udder bottom height, udder width, udder circumference, udder volume and teat angle was found to be 190.46±3.43 day, 1.24±0.04 kg, 237.65±9.67 kg, 892.17±100.87 * 10
