The periparturient relaxation of immunity (PPRI) against parasites in ewes has a nutritional basis. We investigated whether ewes experience a reduction in food intake (anorexia) during PPRI and if the magnitude of anorexia is affected by host production potential and dietary protein supplementation. We also investigated whether nematode infection is linked to plasma leptin concentrations in per...

The symbiotic association of var. (formerly named ) with perennial ryegrass () leads to the production of ergovaline (EV) and lolitrem B (LB) that are toxic for livestock. The objectives of this study were to determine the effects of feeding endophyte-infected ryegrass (SE+) hay on 16 lactating ewes (BW 80 ± 10 kg) in comparison with endophyte-free ryegrass (SE-) hay to investigate the putative...

Ergovaline (EV) produced by symbiotic association of Epichloë coenophiala with tall fescue (Lolium arundinaceum) causes toxicoses in livestock. In this study, 16 lactating ewes (BW 76.0 ± 0.6 kg) were used to determine the effects of feeding endophyte-infected (FE+) or endophyte free (FE-) tall fescue hay on animal health and performances and to investigate the putative mechanisms of action of ...

  Background:Chronic active adrenocorticotropin hormone (ACTH) immunization of ewes (with a previous history of immunization) resulted in elevated titres of antibody against ACTH, which induced a reduction in circulating levels of cortisol. Objectives:<span style="color: win...

This simulation study investigated the farm-level economic benefits of a genetic improvement scheme using artificial insemination (AI) with fresh ram semen in dairy sheep of the Chios breed in Greece. Data were collected from 67 farms associated with the Chios Sheep Breeders' Cooperative 'Macedonia', describing the percentage of ewes that would be artificially inseminated in the flock, pregnanc...

background:chronic active adrenocorticotropin hormone (acth) immunization of ewes (with a previous history of immunization) resulted in elevated titres of antibody against acth, which induced a reduction in circulating levels of cortisol. objectives:the aim of the present study was to investigate: a) the influence of active immunization against acth on milk production of the ewe as assessed by ...

The aim of the study was to evaluate effect body condition score (BCS) at lambing over resumption ovarian and estrous postpartum activity in lactating Pelibuey ewes. Twenty ewes were assigned two groups, according BCS lambing: Low (LBC, n = 10) High (HBC, 10). Ovarian activities daily monitored from day 3 until first or 90 days postpartum. Continuous variables analyzed using Student´s t test bi...

AbstractThe current study aimed to evaluate milk fat and fatty acids profile, nutrients digestibility lactating ewes’ performance as a response supplementing diets with spirulina algae or fish oil in barki ewes. Three experimental were used follow: Control diet based on 60:10:30 concentrate feed mixture (CFM), clover hay, bean straw (T1); control supplemented 10 ml of oil/ kg DM (T2), 5 g Spiru...

Thin-tailed sheep are the most widely kept species in Indonesia. The neutrophils and lymphocytes (N/L) ratio can be a stress indicator for sheep. Stress conditions cause animals to experience impaired growth, productivity, behavioral changes. However, study of thr N/L during pregnancy lactation thin tailed is still lacking variations physiological status such as condition differences ratio. Thi...
