The aims of this study were to evaluate the traits of reproductive, milking and growth performance of Saanen and Saanen × Hair crossbreds (F1, B1 and B2) raised at the Bandırma Sheep Research Institute. The data were collected from 868 goats for reproductive performance and milk yield and from 1077 kids for survival performance between 2009-2012. Milk components (fat, protein, lactose and non-fat dry matter) of goats (n=162) and body weight changes of kid’s (n=64) were evaluated for one year in 2012. Estrus rates and survival rates were similar among all genotypes. Kidding rate was significantly higher in F1 goats than Saanen goats. Saanen goat had the lowest average mean daily milk yield compared with other genotypes. The effect of year and age were significant on milk yield. Goats in F1 and B1 genotypes had higher milk protein percentage and non-fat dry matter content in comparison with Saanen and B2 genotype. Milk fat and lactose contents were similar among genotypes. Birth weight and monthly live weight were similar between genotypes while weaning weight, six month live weight and yearling live weight were higher in B1 kids in comparison with Saanen kids. The effect of dam age and birth type were significant on birth weight, monthly live weight and weaning weight. The findings related to performance characteristics in goat genotypes investigated show that B1 genotype could be recommend for semi-intensive production system in the Western Anatolia.

This study was conducted to investigate the hatching parameters differences between the hatching eggs which were controlled or not for fertility at 18th day of embryo development in the hatchery unit. Hatching was conducted with hatching eggs of Atak-S commercial layers parent stocks. Four treatment groups were constituted; 1) 95% fertility, fertility control at 18th day, 2) 95% fertility, no fertility control at 18th day, 3) 75% fertility, no fertility control at 18th day and 4) 50% fertility, no fertility control at 18th day. There were no significant differences between the groups in terms of fertility rate, hatching efficiency hatchability of fertile eggs and early-, middle and late period embryo mortality. Chick quality according to Pasgar score chick quality assessment differed significantly between the treatment groups. The results of the present study indicate that transferring of eggs to the hatcher without fertility control at 18th day of embryo development did not affect the hatching results, but chick quality decreased when the fertility rate decreased below 45%.

This study was conducted to examine the soil fertility of the Büyük Menderes Basin, where wheat is widely cultivated. Soil samples were taken from 50 different points at a depth of 0-30 cm and various physical and chemical properties and amounts of nutrient elements were determined. With regard to the results of the study, the soils were generally sandy-clay-loam in texture, with slightly alkaline reaction, limy, rich in organic matter and showed no risk of salinity. The examined soils were found to be insufficient as 34% for total N, 14% for available K, 26% Mg, 10% Fe, 94% Zn and 98% Mn contents while all of the soils were determined as sufficient in terms of available P, Cu and Ca contents. When relationships between nutrient elements and soil physical-chemical properties were examined, negative correlations were found between soil pH and EC, organic matter, total N, available K, Zn; lime contents and available Mg, Fe, Cu; clay and available K and Mn contents. The positive correlations were found between EC and available K, Ca and Zn; organic matter % and total N, available K, Cu, Zn and Mn; sand % and available Mn; clay % and available Fe contents. Investigation of relationships between plant nutrients demonstrated that, there were positive correlations between total N and available K, Cu, Zn, Mn; available P and Zn; available K and Cu, Zn, Mn; available Ca and Fe; available Mg and Fe, Cu; available Fe and Cu, Mn; available Cu and Mn contents. The results of the study showed that attention should be paid to fertilization programs to fertilization with Zn and Mn, which were found to be insufficient in the greater part of the basin’s soils, and also to nitrogen deficiency is observed, as this directly affects the protein content of wheat.

This study was carried out to determine the effect of non-genetic factors on growth and reproductive traits in Saanen goats. For this aim, total of 274 Saanen goats and kids were investigated for growth and reproductive traits in South Marmara Region of Turkey. Fertility parameters were evaluated during two reproductive years. Saanen kids were measured from birth to 6 months of life. The average live weights at birth, weaning, 60th, 90th, 120th and 180th days of age were calculated and determined as 3.05±0.04kg, 11.80±0.27kg, 12.26±0.08kg, 14.20±0.32kg, 17.41±0.45kg, 25.01±0.65kg, respectively. The effects of sex and birth type on live weights until 90th days of age; maternal age only on birth weight; month at birth on all of investigated days were found significant statistically. The pregnancy, birth rate per pregnancy (BRP), birth rate per mating (BRM), infertility, abortion, kidding rate (single, twin or triplet), survival rate (until weaning), number of kids per parturition (NKP), number of kids per mating (NKM) were found; 92.98%, 85.07%, 91.25%, 7.02%, 8.75%, 36.12%, 49.00%, 14.88%, 89.13% and 1.74±0.06, 1.42±0.07 respectively. The effects of maternal age on all rates (out of BRM and abortion rate); the year on birth, abortion, single kidding rate, survival rate and NKM were found significant for reproductive traits. The advanced reproductive performance and rapid growth rates were observed in Saanen goats. Environmental factors such as age, year, sex, birth type and month at birth were found significant on some growth and reproductive traits in Saanen. So consideration of these factors could be useful as a selection criteria in dairy goat breeding.

This study was conducted to determine the effect of rearing quails in different rearing systems on egg production, egg quality characteristics, and incubation results. The 360 quails were distributed equally to 3 different rearing groups (cage, enriched cage, and floor) in a male:female mixed at the age of 3 weeks. The eggs were individually weighed and recorded one by one daily (5487 eggs) for 3 months. To determine egg quality and incubation characteristics, 750 eggs were broken, and 3284 eggs were incubated, respectively. The results showed that female quail in the floor group have lower body weight at 6 weeks old (177.19 g), and they reached sexual maturity (age of first egg laying) later (65.36 day, P<0.01), The lowest egg production (61.14%) occurred in the floor group during the 3-month egg production period (P<0.05). The lowest average egg weight (9.07 g) was determined in the floor group (P<0.05). It was determined that the eggs of quails raised in the enriched group had a rounder shape index because they have larger widths (P<0.01). While the highest average yolk height (11.24 mm) was determined in the enriched cage group (P<0.01), the highest averages of albumen length (72.41 mm) and lowest averages of yolk index (48.43%) were determined in the cage group (P<0.01). The lowest average values (113.17) in Haugh unit were detected in the floor group (P<0.05). The highest fertility rate (98.44%) was in Floor♂:Cage♀, the highest hatchability of fertile egg rate (94.67%) was obtained from Enriched♂:Cage♀, and the highest hatchability (89.10%) was obtained from Floor♂:Cage♀ pairing (P<0.05). The lowest fertility rate (88.00%) was obtained from the Enriched♂:Floor♀, the lowest hatchability of fertile egg rate (86.01%) was obtained from the Enriched♂:Enriched♀, and the lowest hatchability (75.62%) was obtained from the Enriched♂: Enriched♀ groups. As a result, it has been revealed that the effect of various rearing systems is different on egg production, egg quality traits, and hatching results in quails. Thus, it has been shown that different programs at the rearing period to be applied to the male and female quails can achieve better incubation results and reproductive success.
