Este estudio evaluó el secuestro de carbono orgánico del suelo (COS) en cuatro coberturas vegetales (vegetación secundaria [VS], plantaciones forestales Eucalyptus globulus [EUC] y Pinus patula [PIN] pasturas [PAS]) su correlación con las propiedades fisicoquímicas suelo. Se tomaron muestras a dos profundidades horizonte A (0-10 10-20 cm). Igualmente, se midieron variables para evaluar relación...

six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. the chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. each treatment had 150 bir...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal sciences university poultry farm to find out the effects of different oils on productive performance of broilers. the chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. each treatment had 150 birds, with...

Porcine Epidemic Diarrhea Virus (PEDV), Porcine Delta Corona Virus (PDCoV), and Transmissible Gastroenteritis Virus (TGEV) are major threats to swine health and contaminated feed plays a role in virus transmission. The objective of our study was to characterize inactivation of PEDV, PDCoV, and TGEV in various feed ingredient matrices. Samples of complete feed, spray dried porcine plasma, meat m...

Effects of addition of a mycotoxin detoxifier in poultry feed were studied in broilers. Aflatoxins were present in the poultry feed as 28 ppb (normal feed), 78 ppb (contaminated feed) and 170 ppb (highly contaminated feed). The mycotoxin detoxifier was used in 3 concentrations i.e. 1, 3 and 5 kg/ton of feed. Aflatoxins reduced the body weight in broiler chicken and treatment of contaminated fee...

AIM To study the effect of enteral feeding on splanchnic blood flow velocity in preterm infants. METHOD Coeliac axis and superior mesenteric artery (SMA) blood flow velocity were measured longitudinally in a cohort of 61 babies using Doppler ultrasound. RESULTS Babies fed 1 hourly had significantly higher preprandial SMA peak systolic velocity (PSV) than those fed 3 hourly (70 vs 53 cm/s). ...

Web feeds are a popular way to access updates for content in the World Wide Web. Unfortunately, the technology behind web feeds is based on polling. Thus, clients ask the feed server regularly for updates. There are two concurrent problems with this approach. First, many times a client asks for updates, there is no new item and second, if the client’s update interval is too large it might be no...
