Effects Of Shell Thickness, Shell Pores And Egg Weight Loss On Hatchability On Japanese Quail Eggs, S. Kudret Saylam, Musa Sarica Jan 1999

Effects Of Shell Thickness, Shell Pores And Egg Weight Loss On Hatchability On Japanese Quail Eggs, S. Kudret Saylam, Musa Sarica

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to determine the effects of eggshell thickness, pores, and weight loss on hatchability on Japanese quail eggs. A total of 477 eggs, collected within 5 days, placed in an incubator after determining individual egg weights, and eggs were individually weighted on 5, 10, 14, and 18th days of incubation. Percentage egg weight loss was calculated for individual eggs for each incubation interval. On day 18 of incubation, all unhatched eggs were opened and examined macroscopically for evidence of stage of embryonic development. Egg types were classified as infertile (INF), early dead (ED), late dead (LD), embryos …

The Effect Of Different Levels Of Nutrition At Last Period Of Gestation On Liveweight Of Ewes, Growth And Survival Rates Of Their Lambs, İsmai̇l Fi̇lya, Ali̇ Karabulut, Vedat Akgündüz

Turkish Journal of Veterinary & Animal Sciences

The animal material of the research was 3, 4 and 5 years old 210 Merino ewes and their lambs. The research was started at the beginning of the last 1.5 months period of gestation and continued until the lambs were reached 60 days age. It has been determined that 500 g and more (especially 1500 g) concentrate feed given fed ewes daily at the last 1.5 months period of gestation increased the liveweight and decreased the weight loss of ewes and increased birth weight, growth and survival rates of lambs.

The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt Jan 1999

The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt

Turkish Journal of Veterinary & Animal Sciences

In general, marine fish larvae require \omega-3 HUFA, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Larval growth, survival and larval activity are affected by dietary levels of essantial fatty acids. Some pathological signs, such as abnormal pigmentation, hydrops etc. and low feed conversion efficiency, poor growth, mass mortality are related to \omega-3 HUFA series fatty acids deficiency in larvae food. EPA/DHA ratio in live foods or microencapsuled diets is an important factor in larval development and survival.
