The silent information regulator (Sir2) family proteins are NAD+-dependent deacetylases. Although a few substrates have been identified, functions of the bacteria Sir2-like protein (CobB) still remain unclear. Here the role of CobB on Escherichia coli chemotaxis was investigated. We used Western blotting and mass spectrometry to show that the response regulator CheY is a substrate of CobB. Surf...

The influence of Moringa oleifera (MO) leaf extract as a dietary supplement on the growth performance and antioxidant parameters was evaluated on broiler meat and the compounds responsible for the corresponding antioxidant activity were identified. 0.5%, 1.0%, and 1.5% w/v of MO leaf aqueous extracts (MOLE) were prepared, and nutritional feed supplemented with 0%, 0.5%, 1.0%, and 1.5% w/w of MO...

UNLABELLED Spinal curvatures alter measured stature and may influence the evaluation of skeletal maturity and growth based on stature measurements. METHODS A dataset of calibrated measurements of vertebral positions of 407 radiographs in the frontal plane, together with clinically measured Cobb angles was used to determine the difference between spinal length and spinal height ('height loss')...

An experiment was conducted to assess how hatchability performance of eggs is affected by line and age female broiler breeders. Response variables analyzed were hatchability, infertility, pipping (i.e., pipped shell but not emerged), embryonic mortality (1st, 2nd, 3rd wk), malposition. The trials involved a total 2,880 fertile from two breeder lines (Ross 308 Cobb 500) at different ages (30 50 ...

This experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (Cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. The chicks were randomly distr...

The aim of this paper was to examine the influence of sex, age and nutrition system on mass and yield of major parts in broiler chicken carcass from different genotypes. Research material was one-day chicken of Hubbard Classic and Cobb 500 genotypes fattened 49 days in production conditions. The chicken used two nutrition systems. The first nutrition system had higher level of energy and E : P ...

El objetivo del estudio fue evaluar el efecto de dos niveles (0.5 y 1%) inclusión harina laritaco (Vernonanthura patens) en comportamiento productivo morfometría intestinal pollos engorde. Se utilizaron 588 pollitos machos la línea Cobb 500, distribuidos un diseño bloques tres tratamientos con siete repeticiones cada uno, considerándose como unidad experimental grupo 28 pollos. No hubo diferenc...
