Housing lactating sows with piglets in a multi-suckling pen from around 14 days post-farrowing is common practice in Swedish organic piglet production. However, nursing-suckling interaction is less frequent in multi-suckling pens than in individual farrowing pens, thus affecting piglet performance, e.g., piglet growth. Moreover, piglet mortality is higher in systems using multi-suckling pens. T...

the objective of this study was to determine the effects of supplemented selenium (se) on plasma cortisol, red blood cell glutathione peroxidase activity (rbc gsh-px-1), concentration of immunoglobulin g (igg) and body weight in pneumonic suckling calves. ten holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...

Marshall, Ronald G. (Army Chemical Corps, Fredrick, Md.), and Peter J. Gerone. Susceptibility of suckling mice to variola virus. J. Bacteriol. 82:15-19. 1961.-The susceptibility of suckling mice inoculated intraperitoneally or intracerebrally with variola virus was investigated. Data are presented that define the death patterns, the relationship of incubation period to dose of virus inoculated,...

The reproductive performance of postpartum cows is affected by factors such as suckling and nutrition. We investigated the effect of a restricted suckling period on the superovulatory response and the fertility after flushing in postpartum Japanese Black cows. Forty-seven postpartum cows were used in this study. At 7 days postpartum, the cows were divided into 2 groups: (1) continuous access to...

BACKGROUND & AIMS Previous studies have suggested that iron absorption in suckling mammals is refractory to stimuli that normally would decrease absorption in adults. To better understand the regulation of iron absorption during suckling, we have characterized the relationship between hepcidin, ferroportin, and iron absorption at this crucial stage of life. METHODS To determine whether ferrop...

evaluation of gastric emptying rate using nuclear scintigraphy as the gold standard method has been studied in various animals, but there is no report in suckling lambs. the aim of this study was to develop a nuclear scintigraphic method to visualize and measure abomasal emptying rate by estimation of scintigraphic half emptying time (t1/2) in the live neonatal lamb. five healthy, female irania...

Hatano high-avoidance (HAA) and low-avoidance (LAA) animals were originally selected from Sprague-Dawley rats for good and poor active avoidance learning in a shuttle box. We studied the endocrinological profile in lactating rats to determine the effect of suckling during mid-lactation in HAA and LAA rats. The pups were separated from their mother rats 6 h before the onset of suckling and blood...

a total of 20 suckling sanjabi lambs, comprised of 10 males and 10 females with respective liveweights of 13.40±1.34 and 11.62±0.85 kg were employed in a 2x2 factorial experimental arrangement. the lambs within their sexes were grouped according to their liveweights and then randomly allocated to either one of the two treatments namely: ad libitum good quality alfalfa hay plus free suckling (co...

The objective of this study was to determine the effects of supplemented selenium (Se) on plasma cortisol, red blood cell glutathione peroxidase activity (RBC GSH-PX-1), concentration of immunoglobulin G (IgG) and body weight in pneumonic suckling calves. Ten Holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...
