Prüfung auf reduzierende organische Verbindungen mit o-Dinitrobenzol in der Tüpfelanalyse

Abstract: Organische Verbindungen, die in alkalischer Losung als Wasserstoffdonatoren fungieren, reduzieren alkoholisch-alkalische Losungen von o- und p-Dinitrobenzol zu blauvioletten bzw. orangefarbigen wasserloslichen Alkalisalzen von chinoiden Stickstoffsauren. Die empfindliche Redoxreaktion mit o-Dinitrobenzol kann in der Tupfelanalyse als selektive Vorprufung verwendet werden. Die bei 16 Verbindungen ermittelten Erfassungsgrenzen liegen zwischen 2 und 25μg reduzierender Substanz im Tropfen.

Características qualitativas da pastagem de aveia preta e azevém manejada sob diferentes alturas, obtida por simulação de pastejo

Abstract: This trial aimed to evaluate the nutritive value of black oat and ryegrass pasture submitted to different heights of grazing. The study was carried out in Experimental Farm from Cooperativa Agropecuaria Mouraoense – COAMO in Campo Mourao city, Parana State, Brazil. Experimental area corresponded to 8 ha, with randomized blocks design, with four treatments, which corresponded to four heights of pasture: 7, 14, 21, 28 cm and two replications. Samples were collected by hand-plucking. Average values of crude protein were 23,8%; 21,8%; 20,8% and 20,9% for 7; 14; 21 and 28 cm, respectively. The crude protein contents presented quadratic response to height of pasture. Quantities of acid detergent fiber (ADF) were 25,5%; 28,0%; 27,2% e 26,0% for 7; 14; 21 and 28 cm, respectively. Values of neutral detergent fiber (NDF) were 58,5%; 62,2%; 59,7% e 60,5% for 7; 14; 21 and 28 cm treatments, respectively. The quantity of ADF and NDF did not show statistic difference between heights of grazing.

Genetic study of litter size and litter uniformity in Landrace pigs

Abstract: We aimed to estimate litter size and litter uniformity genetic parameters and genetic trends of Landrace pigs at birth and at three weeks by using multitrait analyses for 2,787 litters. The following litter traits were evaluated: number of piglets born alive (NBA), within-litter weight mean at birth (MBW), within-litter weight standard deviation at birth (SDB), within-litter weight coefficient of variation at birth (CVB), number of piglets at three weeks (NT), within-litter weight mean at three weeks (MT), within-litter weight [...]
