[ 1 ] - Performance, Health Status, and Colostrum Yield of Twin-Bearing Afshari Ewes as Well as Growth and Survival of Their Offspring are not Affected by Increasing Dietary Metabolizable Protein in Late Pregnancy
The aim of this study was to investigate the effects of two dietary metabolizable protein (MP) concentrations on the performance and health status of Afshari ewes and survival and growth of their lambs during late pregnancy. For 6 weeks prior to lambing, 32 Afshari ewes were randomly assigned to two dietary treatments, containing low (LMP) or high (HMP) MP concentrations. The ewes in LMP (n=16)...
[ 2 ] - Exogenous Polysaccharidases for Young Ruminants: A Review Interfacing Nutrition, Economics, and Health
Neonate ruminants possess little cell-wall and starch degrading enzyme activity. Importantly, early establishment of fibrolytic, amylolytic, and proteolytic capacities is influential for the early expansion of the reticulorumen epithelia. Such an early development in reticulorumen fermentation will enable a timely hepatic adaptation to volatile fatty acids assimilation. The early nutrient relea...
[ 3 ] - Eating Time Modulations of Physiology and Health: Life Lessons from Human and Ruminant Models
Tissue nutrient supply may be synchronized with endogenous physiological rhythms to optimize animal and human health. Glucose tolerance and insulin sensitivity have endogenous rhythms that are not essentially dependent on food type and eating. Human glucose tolerance declines as day comes into night. Based on such evolutionary findings, large evening meals must be avoided to reduce risks of vis...
[ 4 ] - A novel farm technology to quantify dairy cow cervix morphology: oestrus versus non-oestrus models
The objective was to quantify and compare cow cervical morphology on oestrus vs. non-oestrus daysusing a new farm technology. The cervical tissues were videotaped using a cervixscope involving newcamera equipment in four Holstein cows on multiple oestrus and non-oestrus days to score tissue morphology as altered by oestrus. The non-oestrous days were in diestrus phases. The videotaped records w...
