İneklerde reprodüktif bozukluklar, üreme verimliliğinin azalmasının ana belirleyici faktörüdür. Dünyada olduğu gibi ülkemizde de süt üretimindeki ekonomik kayıpların en önemli nedeni sistemi enfeksiyonlarıdır. Enfeksiyon kaynaklı infertilitenin büyük bir bölümüne bakteriyel etkenler neden olur. Bu çalışma, 56 adet Holstein ırkı düvede 3 grup halinde yürütülmüştür. Grup I; bulanık ve irinli çara...

Fast Breeder Test Reactor (FBTR) operating at IGCAR since 1985 is testimony of maturity India has attained in Fast Breeder Technology. The reactor has operated exceedingly well thus established the competence of Indian engineers in handling this difficult technology where large quantity of sodium is used for cooling of reactors. INDIA took quantum leap from 40 MWe FBTR to launch of 500 MWe Fast...

Trace minerals, such as Zn, Mn, and Cu, are components of eggs that are essential for broiler breeder performance as well as chicken embryo development [1, 2]. These trace minerals are constituents of several proteins involved in intermediary metabolism, hormone secretion, and the immune system [3] and are required in small amounts in the diet. The effects of Zn, Mn, and Cu deficiencies on bree...

Past research on feed restriction methods with turkey breeder hens has involved the feeding of 1) high-fiber or low-energy diets, 2) low dietary protein, 3) limited quantities of feed, 4) rations on a skip-a-day program, 5) distasteful compounds, or 6) combinations of these methods. In general, feed-restricted turkey breeder hens showed a reduction in BW and a delay in sexual maturity at time o...
