the main objective of this study was to evaluate the effect of dietary inclusion of wheat or corn as the main source of starch in prepartum diets on colostrum composition, colostrum igg1 and igg2 concentrations, serum igg1 and igg2 concentrations of calves and efficiency of igg1, igg2 and total ig absorption. for this purpose, thirty primiparous and twenty multiparous holstein cows were used in...

Nemaguard has been the workhorse rootstock of the California almond industry for many decades. It is well adapted to the well-drained, non-calcareous loam and sandy loam soils common throughout the San Joaquin Valley. Nemaguard is vigorous, immune to rootknot nematode, compatible with all almond varieties, doesn’t sucker much, has decent anchorage and is easy to grow at the nursery. However, th...

Haplorchis popelkae n. sp. is described from the intestine of the short-necked turtles Elseya dentata and Emydura victoriae in Northern Territory, Australia. This slipper-shaped heterophyid digenean differs from the 9 previously known species of Haplorchis in its larger overall size, a forebody that is wider than the hindbody, comparatively short ceca, and a ventral sucker that is less heavily ...

We examined the behavioural ecology of mothers and calves during the first year of life to identify variables predicting calf mortality among bottlenose dolphins. Specifically, we investigated whether the primary cause of calf mortality was poor calf condition or shark predation. Seventy-five per cent of calves that died (NZ 12) showed visible signs of poor health compared with 4.7% of the surv...

Context Baleen whale calves rapidly increase in size and improve locomotion abilities, while on their low-latitude breeding ground, allowing them to undertake a successful migration high-latitude feeding grounds. Aims We investigated energy expenditure resting behaviour of humpback (Megaptera novaeangliae) mother–calf pairs regard changes calf length an undisturbed breeding/resting ground off E...

Antibodies to purified calf thymus Fl, and to chromatographically purified subfractions of calf thymus Fl histones were induced by immunization of rabbits with histone-RNA complexes. Complement fixation studies with these antibodies demonstrated structural differences between the subfractions in one organ and between those of different organs and species. The anti-F1 sera showed varying reactiv...
