Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....

The purpose of the study was: (1) to test if the reindeer mammary gland (udder) could tolerate regular long-term machine milking, (2) to record milk yield of reindeer exposed to regular long-term machine milking and (3) to document changes in milk composition through a 3 months experimental period (July, August and September 1999). Adult female reindeer were allotted to four groups of four. Tre...

Effects of dietary supplementation inulin in dairy cows were investigated this study. Thirty-six mid-lactation Holstein randomly divided into six groups with per group and offered a total mixed ration supplemented 0 (control), 50, 150, 200, 250 350 g/d head, respectively. The animals pre-fed for 2 weeks before rumen fluid, milk blood samples collected weekly 3 weeks. With increasing doses, yiel...

In the current study, 3 groups with similar characteristics were formed in Uşak Cattle Breeders Association Research Farm. A total of 21 cows, which third and fourth lactation, selected grouped as including 7 Holstein cows each group. The animals first group given 143 g / kg calcium propionate second give 30 mg trisodium citrate orally for two months. received no additives a control farm where ...

The objectives were to investigate effects of nutritional plane and Se supply during gestation on yield and nutrient composition of colostrum and milk in first parity ewes. Rambouillet ewe lambs (n = 84, age = 240 ± 17 d, BW = 52.1 ± 6.2 kg) were allocated to 6 treatments in a 2 × 3 factorial array. Factors included Se [adequate Se (ASe, 11.5 µg/kg of BW) or high Se (HSe, 77.0 µg/kg of BW)] ini...

background & objective: there are many common infections and inflammations among people over the world. this demands an affordable and reliable test with high sensitivity/specificity to predict or confirm the diagnosis of such cases in routinely clinical practice. in the present study, we aimed to find any potential correlation between serum levels of ggt and crp- q and/or hs- crp and wbc c...

Prophet of POU1F1 (PROP1) plays direct or indirect important roles in the morphogenesis of pituitary gonadotropes as well as lactotropes, somatotropes and caudomedial thyrotropes. It also controls the expression of growth hormone, prolactin and thyrotropin subunits through regulatory PIT1 factor. These hormones have important influences on production traits in most animal species including the ...
