The aim of the study was to investigate the effect of different levels of protein in a diet on the incorporation of endogenous urea nitrogen (EUN) into individual amino acids (AA) of the ruminal bacteria of goats fed a low- (LP), medium- (MP), or high-protein diet (HP) in a 3 × 3 Latin square design. Three Alpine goats of about 35 kg body weight fitted with cannula into the rumen and catheter into the jugular vein were fed three isoenergetic diets containing 11% (LP), 13% (MP), or 16% (HP) crude protein in dry matter. The goats were infused for 6 days continuously with an 15N urea solution into the jugular vein. Ruminal bacteria were hydrolysed with 6M HCl. Next, butyl derivatives of free bacterial AA were obtained using HCl in butanol, then N-acylated using trifluoroacetic acid anhydride and analysed by gas chromatography using a mass-selective detector. The concentration of urea in plasma was 178, 356 and 667 mg · l–1 in goats from groups LP, MP and HP, respectively. 15N-excess during the infusion of labelled urea was significantly higher (P < 0.05) in the vast majority of AA of ruminal bacteria from goats fed the LP diet in comparison with goats fed the HP diet. Therefore, the level of protein in the diets affects the incorporation of EUN into bacterial AA. With the LP diet, EUN was incorporated mostly into glutamic acid, isoleucine and arginine, while in the case of the HP diet, into glutamic acid and arginine, as well as methionine. Regardless of the level of nitrogen in the diets, the incorporation of 15N into proline was very low. Irrespective of the dietary nitrogen level, EUN appears to be predominantly used for synthesis of glutamic acid in ruminal bacteria.

Festuca arundinacea (Fa) is one of the most drought-tolerant species within the Lolium-Festuca complex. In the current work the protein level of chloroplastic Cu-Zn SOD (superoxide dismutase) in two Fa plants with extreme values of drought tolerance during exposition to water deficit was investigated. The obtain results revealed higher level of enzyme accumulation in more drought-tolerant Fa genotype. In less-drought tolerant plant the increase of dismutase level during stress treatment was only slight.

Festuca arundinacea (Fa) jest jednym z najbardziej odpornych na suszę gatunków w obrębie kompleksu Lolium-Festuca. W niniejszej pracy badano wpływ deficytu wodnego na poziom białka Cu-Zn SOD (dysmutaza ponadtlenkowa) u dwóch genotypów Fa charakteryzujących się skrajnymi wartościami tolerancji na suszę. Wysoką akumulację enzymu podczas stresu obserwowano u rośliny bardziej odpornej na suszę, podczas gdy u rośliny mniej odpornej wzrost poziomu dysmutazy był jedynie nieznaczny.

Possibility of reduction of protein level in feed mixtures of similar content of amino acids digestible in the small intestine and its influence on fattener’s performance and nitrogen retention were determined. Thirty pigs (35 kg) were divided into 3 groups. The control animals were fed with diets with crude protein level suggested by polish pig feeding standards (Normy żywienia... 1993) – 17% in grower and 15% in finisher diet. In the experimental groups (I and II) the protein level was reduced about 10 or 20% respectively. No significant effect on feed intake, weight gains and feed utilization was found. The animals from the both experimental group utilized less crude protein (P=0.001) than in Control group. The significant (P=0.001) reduction in nitrogen excreted in urine and total N-excretion in both group with reduced protein level in feed mixtures, were observed. Nitrogen retention in g/day was higher for group I compared to other groups and N-retention : N intake were significantly higher (P<0.05) in both experimental groups. The reduction of crude protein level in the experimental diets did not affect slaughter performance but in group II the tendency to increase (P=0.064) in back fat thickness and decrease meat content in carcass, were observed. The results suggest that lowering the protein level in diets for high-meat crossbred pigs (Polish Large White × Polish Landrace) × (Hampshire × Pietrain) from 170 and 150 g kg⁻¹ to 136 g and 115 g kg⁻¹ in grower and finisher diets, respectively, but supplemented with synthetic amino acids, did not impact negatively production results of fatteners, but decreased nitrogen emission to the environment and cost of feed.

Celem badań było określenie wpływu obniżenia poziomu białka w mieszankach dla tuczników, zbilansowanych pod względem zawartości aminokwasów strawnych w jelicie cienkim, na wyniki produkcyjne, wydalanie azotu i jakość tuszy. Trzydzieści świń (35 kg) podzielono na 3 grupy. Zwierzęta kontrolne otrzymywały mieszanki z poziomami białka rekomendowanymi przez Normy żywienia... 1993 – 17% w mieszance grower i 15% w mieszance finiszer. W grupach doświadczalnych (I i II) poziom białka był obniżony o odpowiednio 10 lub 20% w stosunku do grupy kontrolnej. Nie stwierdzono znaczących różnic w pobraniu pasz, dziennych przyrostach masy ciała oraz wykorzystaniu paszy. Zwierzęta z obu grup doświadczalnych pobierały mniej białka ogólnego niż zwierzęta z grupy kontrolnej (P=0.001). Stwierdzono istotne (P=0.001) obniżenie ilości całkowitego wydalonego azotu i azotu wydalonego w moczu w obu grupach doświadczalnych w porównaniu z grupą kontrolną. Retencja azotu w g/dzień oraz stosunek retencji azotu do azotu pobranego były istotnie wyższe (P<0.05) w obu grupach doświadczalnych w stosunku do grupy kontrolnej. Redukcja poziomu białka w mieszankach doświadczalnych nie wpłynęła istotnie na wydajność rzeźną świń, jednakże w grupie II zaobserwowano tendencję (P=0.064) do wzrostu grubości słoniny i obniżenie udziału mięsa w tuszy. Wyniki badań sugerują, że obniżenie poziomu białka w mieszankach dla wysoko mięsnych tuczników (wbp × pbz) × (Ha × Pi) ze 170 na 136 g kg⁻¹ w mieszance grower i ze 150 na 115 g kg⁻¹ w mieszance finiszer, z jednoczesnym uzupełnieniem niedoborów aminokwasów za pomocą aminokwasów krystalicznych, nie wpływa negatywnie na wyniki produkcyjne tuczników, ale obniża wydalanie azotu do środowiska i koszt żywienia.

H. pylori ureA and ureB genes encoding both subunits of urease were expressed transgenically in a low-alkaloid line of tobacco (LA Burley 21). Analysis of transgene expression at both the mRNA and protein levels revealed a significant increase (up to 8-fold) in ammonia concentration correlated with an amount of UreB protein detected in the leaves, and an increase (up to 2-fold) in urease activity in transformants as compared to control plants.
