Abstract Inadequate nutrition during gestation has been shown to impair growth and metabolism of affected offspring can predispose them lifelong inefficiency poor performance. Development throughout preweaning studied compared carcass performance; however, the impact nutrient challenge on post weaning growth, efficiency, utilization is not well known. Thus, our objective was investigate impacts...

I. In Expt I , four adult wether sheep were given diets of hay or dried grass in an alternating sequence of feeding treatments. Each treatment period lasted for 20 days and blood samples were taken from the sheep on the last day of each period. When the diet of hay (linoleic: linolenic acid ratio 1.40) was replaced by one of dried grass (1inoleic:linoltnic acid ratio 0.28), there was an increas...

We consider the nonlinear Schr\odinger equation with combined nonlinearities, where leading term is an intracritical focusing power-type nonlinearity, and perturbation given by a defocusing one. completely answer question wether ground state energy, which threshold between global existence formation of singularities, achieved. For any prescribed mass, for mass-supercritical or mass-critical per...

A graph homomorphism from a graph G to a graph H is a mapping h : V (G)→ V (H) such that h(u) ∼ h(v) if u ∼ v. Graph homomorphisms are well studied objects and, for suitable choices of eitherG orH, many classical graph properties can be formulated in terms of homomorphisms. For example the question of wether there exists a homomorphism from G to H = Kq is the same as asking wether G is q-colour...

Twelve Dorper × Pelibuey wether lambs (26.8 ± 1.6 kg initial BW, 5 mo of age) were used to evaluate effects of zilpaterol hydrochloride (ZH) on feedlot performance, and effects of ZH and ZH supplementation period (15 and 30 d) on nutrient intake and digestibility. Lambs were blocked by initial BW, and assigned randomly within BW blocks to 1 of 2 treatments: i) control (no ZH), and ii) supplemen...

We present the main results of a complete study concerning a small metallic statuette. A collaboration involving metallurgy, optics, computer graphics, archaeology and engineering specialists was needed. The virtual optical aspect computations obtained by spectral simulation is founded on optical measurements of metallic samples wether smooth or rough. The scientific study concerns a small stat...

Over a 2-year period, crossbred lambs resulting from the mating of Texel (T), Romanov (R), and St. Croix (S) rams with Polypay (P) and S ewes, were finished during the summer and late fall to determine feedlot performance and carcass characteristics. A total of 175 wether lambs of the five genotypes (R x P, R x S, S x S, T x P and T x S) were fed a high-energy diet for an average of 110 d (Expe...

Defined mixtures of two grass (orchardgrass, perennial ryegrass) and two legume (alfalfa, red clover) hays, harvested in two cuttings in 2 yr, were fed in digestibility, intake and mineral balance trials to wether lambs. Each mixture was fed in ad libitum amounts to six crossbred wether lambs weighing 35 to 45 kg. The effect of increasing proportion of legume in mixtures on dry matter digestibi...
