Consequences of infection pressure and protein nutrition on periparturient resistance to Teladorsagia circumcincta and performance in ewes
(2009)The consequences of protein nutrition on the degree of periparturient relaxation of immunity to nematode parasites in sheep may be more pronounced at higher levels of infection pressure. Here, we investigated interactive ... -
Effects of maternal protein nutrition and subsequent grazing on chicory (Cichorium intybus) on parasitism and performance of lambs
(2010)Forty-eight 4- to 5-yr-old Blackface x Bluefaced Leicester (Mule) ewes and their 24-d-old twin lambs were used to assess the effects of maternal protein nutrition and subsequent grazing on chicory (Cichorium intybus) on ... -
Nutritional sensitivity of periparturient resistance to nematode parasites in two breeds of sheep with different nutrient demands
(2010)The periparturient relaxation of immunity (PPRI) to parasites in mammals is sensitive to both metabolisable protein (MP) supply and animal genotype (different reproductive outputs). We tested the hypothesis that the ... -
Patterns of maternal-offspring behaviour of dairy sheep and potential association with mammary health
(2007)Behaviour during lactation and its relationship with mammary health was investigated in 12 dairy ewes (six with single lambs and six with twins) for 42 d after lambing. Behavioural recordings were made. Samples of teat ... -
Teat disorders predispose ewes to clinical mastitis after challenge with Mannheimia haemolytica
(2006)In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first ... -
Transmission of Mannheimia haemolytica from the tonsils of lambs to the teat of ewes during sucking
(2011)Objective of the work was to study whether Mannheimia haemolytica may be transmitted from the mouth of the lambs into the teat of the dam during sucking. We compared bacterial populations within the teat duct and milk of ...
