Correct projection of breakeven prices is essential to profitable cattle feeding. In order to calculate breakevens correctly, feedlot performance must be predicted accurately. Average daily feed intake (ADFI), average daily gain (ADG), feed conversion (F/G), days on feed, carcass characteristics, morbidity and mortality can vary greatly from one group of cattle to another. This paper will revie...
A Texel muscling quantitative trait locus (TM-QTL) has been identified on chromosome 18, which increases loin muscling, but may also have a negative impact on mechanically-measured loin tenderness in crossbred lambs, depending on conditioning time. This study investigated the influence of a range of conditioning times (3, 5, 7 or 9 days) on the effect of TM-QTL on loin muscle tenderness. Using ...
مقدمه : سرطان سینه از جمله شایعترین بدخیمی ها در زنان ایرانی می باشد که میزان بروز آن 09/17% در هر 100 هزار زن می باشد. میزان بقای 5 ساله این بدخیمی در حدود 75% گزارش شده است. سرطان پستان شایعترین علت مرگ در زنان پس از سرطان ریه بوده و شایعترین محل درگیری آن در ربع فوقانی-خارجی سینه می باشد. مبتلایان به سرطان سینه به دلیل مصرف داروهای مختلف از جمله مهارکننده های آروماتاز در معرض ابتلا به کاهش چ...
With the adoption of visual instrument grading, the calculated yield grade can be used for payment to cattle producers selling on grid pricing systems. The USDA beef carcass grading standards include a relationship between required LM area (LMA) and HCW that is an important component of the final yield grade. As noted on a USDA yield grade LMA grid, a 272-kg (600-lb) carcass requires a 71-cm(2)...
Knowledge of breed effects on carcass and pork quality traits is required to develop commercial crossbreeding programs that emphasize product quality. A 2 x 2 diallel mating system involving Landrace and Duroc pigs was used to estimate individual heterosis, direct breed effects and reciprocal cross differences for post-weaning growth, real-time ultrasound, carcass, and pork quality traits. Data...
abstract this study scrutinized the interaction between linguistic and strategic variables in reading comprehension test performance of iranian efl learners. to this end, the interaction among the participants’ reading comprehension test performance, use of test-taking strategies, and level of language proficiency was analyzed. the participants comprised 286 students who answered a reading comp...
In this issue of Molecular Pharmacology (p. 665), Pannacione et al. provide evidence of a role for the voltage-gated potassium channel alpha subunit Kv3.4 and its ancillary subunit MiRP2 in beta-amyloid (Abeta) peptide-mediated neuronal death. The MiRP2-Kv3.4 channel complex-previously found to be important in skeletal myocyte physiology-is now argued to be a molecular correlate of the transien...
(Co)variance components were estimated for visual scores of conformation (CY), early finishing (PY) and muscling (MY) at 550 days of age (yearling), average daily gain from weaning to yearling (GWY), conformation (CW), early finishing (PW) and muscling (MW) scores at weaning, and average daily gain from birth to weaning (GBW) in animals forming the Brazilian Brangus breed born between 1986 and ...
Myostatin, a member of the TGF-beta family, negatively regulates skeletal muscle development. Depression of myostatin activity leads to increased muscle growth and carcass lean yield. In an attempt to down-regulate myostatin, transgenic mice were produced with a ribozyme-based construct or a myostatin pro domain construct. Though the expression of the ribozyme was detected, muscle development w...
