Effect of Dietary Protein Supplementation on Sheep Milk Coagulation Properties
نویسنده
چکیده مقاله:
The objectives of this experiment were to evaluate the effects of dietary protein supplementation in lactating dairy ewe’s diets on milk coagulation properties. Milk samples (n=126) were analyzed to assess the source of variation for rennet coagulation ability at the 6th (RCA6) and 12th hour (RCA12), milk clotting time (MCT, s) and an index of milk clotting time (IMCT, %). In addition, data were used to determine the influence of dietary protein source (sunflower meal (SFM) vs. rapeseed meal (RSM)) and lactating day (27, 35, 42, 49, 56, 63 and 70) on RCA6, RCA12 and MCT. Eighteen early lactation (4-10 weeks) dairy ewes from the synthetic Bulgarian dairy population breed (SBDP) were allocated into two isonitrogenous (crude protein (CP)=18%, dry matter (DM) basis) dietary treatments (n=9 per diet) formulated to contain equal amounts of fibre, energy, protein digestible in small intestines (PDI) and Ca:P ratio. The rates of MCT (s) were measured as time from rennet addition to onset of rennet-induced gel. RCA values were measured subjectively based on a scale of coagulum characteristics (score 1-3). Results showed a significant effect (P

Effects of sheep/goat whey protein dietary supplementation on the redox status of rats
The purpose of the present study is to estimate the effects of sheep/goat whey protein dietary supplementation on the redox status of blood and tissues of rats. Twelve male Wistar rats were divided into the control group (standard commercial diet) and whey group [standard commercial diet + sheep/goat whey protein (1 g kg b.w/day)] (6 rats/group). The animals were maintainted on their respective...
