An experiment was conducted to investigate the effects of supplementing Lori ewes with rumen-undegradable protein (RUP) in late pregnancy on their performance and that of their lambs. Milk yield and blood metabolite profile were measured. Forty pregnant ewes were used in a completely randomized design trial with four treatments: 1) a basal diet (control); 2) with a supplement of 5% fishmeal; 3)...

Twenty-four barrows (78.1 +/- 1.7 kg of initial BW) were fed a control diet (2.5% sunflower oil) or an experimental diet containing 5% whole extruded linseed. Both diets were supplemented with 170 mg of vitamin E/kg of feed. At slaughter (160 +/- 9.2 kg of BW), 6 hams were collected per group and delivered to Stazione Sperimentale per l'Industria delle Conserve Alimentari of Parma for seasoning...

the aim of this study was to evaluate the effect of glycogenic diets supplemented with different poly unsaturated fatty acids on reproductive performance of iran black ewes in two different managing programs. ewes were allocated in two different groups; group a (n = 75) and group b (n = 25). ewes from group a were stopped from suckling followed by introducing to the rams on days 80 and 90, resp...

background: application of different sources of fatty acids and their effect on ovarian performance is a current issue in animal science and research centers. objectives: the purpose of this study was to determine the effect of different fatty acids in close-up period on population and size of follicles and measuring blood parameters related to the energy state of the body after calving of lact...

The objective of this study was to investigate the effect of incomplete milking during the first 5 days of lactation on the resting behavior of commercial dairy cows. The hypothesis was that the elevated intramammary pressure resulting from milk retained in the udder in incompletely milked cows could lead to a change in lying behavior. This study was a randomized controlled trial in which cows ...

OBJECTIVE This trial was performed to examine the effects of ruminally degradable starch (RDS) levels in total mixed ration (TMR) with low corn-based starch on the milk production, whole-tract nutrient digestibility and nitrogen balance in dairy cows. METHODS Eight multiparous Holstein cows (body weight [BW]: 717±63 kg; days in milk [DIM]: 169±29) were assigned to a crossover design with two ...
