Effects of extruded flaxseed and Salmate inclusion in the diet on milk yield and composition, ruminal fermentation and degradation, and kinetic flow of digesta and fluid in lactating dairy cows in the subtropics.

Background And Aim: Dietary supplements play pivotal roles in promoting productive and reproductive performance in ruminant animals. The aims of the present study were to evaluate the effects of extruded flaxseed and Salmate (Ballard Group, Inc, OH, USA) inclusion in diets on milk yield and composition, ruminal degradation and fermentation, and flow of fluids and digesta in lactating cattle.

Materials And Methods: Six rumen-fistulated Holstein lactating cows were distributed to a 6 × 6 design of Latin square (L.

Sex preselection of sٍheep embryo by altering the minerals of maternal nutrition.

Several methods have been conducted for embryo sex preselection, which includes X- and Y- sperm separation, changing the pH of the female reproductive tract, time of mating before or after ovulation, and feeding formula, such as altering the presence of minerals in diet content before breeding may affect the embryo sex preselection ratio. In this study, three food formulas to feed female sheep were created with the cooperation of the Arabian Agricultural Services Company (Arasco). Ewes were fed with modified food formulas for one month before mating with males.
