Genetic differences in natural vs hormone-induced ovulation rates were compared in immature female mice from five lines that had undergone long-term single-trait and antagonistic index selection for litter size and(or) 6-wk BW. Lines used were control (K); high litter size (L+); high BW (W+); low litter size and high BW (L-W+); and high litter size and low BW (L+W-). Natural ovulation rate at a...

In this paper we determine the sequences of join spaces and Atanassov's intuitionistic fuzzy sets associated with all i.p.s. hypergroups of order less than or equal to 6, focusing on the calculation of their lengths.

Background & Aims: Asthma is a chronic inflammatory disease of the airways which is associated with the triad of cough, wheezing and dyspnea. Allergic asthma is often associated with a personal or family history of allergic diseases and mostly begins at early childhood. Mold is one of the most common irritants of asthma and allergic rhinitis. In the last 20 years there has been 30% increase in ...

The recent efforts to mount an R&D response public health emergencies of international concern have led the formation what we term a biochemical infrastructure vaccine development and production. In principle, this is expected not only curtail existing pandemics but also anticipate contain yet-to-emerge future threats. Critically, by nature its geographical distribution technical modularity, th...

Three experiments were conducted to determine the effects of excess arginine on performance, plasma amino acid levels and N balance of young pigs (initial weights 6.9, 7.0 and 10.3 kg, respectively). In a 28-d growth trial, various amounts of arginine (0 to 1.6%) were added to a conventional starter diet. Addition of arginine decreased (P less than .01) average daily feed intake (ADFI) and gain...

1. Urinary kallikrein excreted by normal rats is significantly increased (P less than 0-001) 2 h after: (a) water loading, (b) water loading plus frusemide, 0-27 mmol (10 mg) per rat, (c) salt loading. In water-loaded rats, 5 i.u. of renin strikingly reduced kallikrein excretion (P less than 0-01) but considerably increased sodium excretion (P less than 0-001). 2. Renal kallikrein, measured by ...

An experiment was conducted to evaluate the effects of breed, sex and plane of nutrition on the growth response to zeranol in Angus and crossbred calves prior to weaning. Eighty-eight heifers and 118 steers received either a high or low plane of nutrition using a first and last grazing technique. Half of the calves in each nutrition group received a zeranol implant (36 mg) at an average age of ...
