Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...

OBJECTIVE To determine, by the creamatocrit measurement, the effect on the fat content of raw and pasteurized donor milk of freezing during 3 months at -20 °C. METHODS The evolution of the creamatocrit measurement (following Lucas technique) on frozen (-20 °C), raw and pasteurized human milk, was analyzed during 3 months. RESULTS The fat content of raw milk (n=44) was 3.19 g/dl at the begin...

Milk was obtained from two captive bred cheetahs. The nutrient content was 99.6 g protein; 64.8 g fat; and 40.21 g lactose per kg milk. Small amounts of oligosaccharides, glucose, galactose and fucose were noted. The protein fraction respectively consisted of 34.2 g caseins per kg milk and of 65.3 g whey proteins per kg milk. Very little variation in milk composition among the individual cheeta...

This experiment was conducted to evaluate the effect of supplementing a fat diet with selenium (Se) and vitamin E on performance of cows, blood antioxidant status and milk fatty acid composition. Sixty-three lactating Holstein cows were randomly divided into seven groups of nine cows each and each group was fed one of the following diets: i) a basal diet (control); ii) a basal diet with 0.15 mg...

this study investigated the effects of five levels of galanin on plasma concentrations of growth hormone , triiodothyronine, thyroxine and milk fat in dairy goat breed was sannan .15 breeds of dairy goats sannan all about the same age and weight were selected for this study and were randomly divided into five treatments ( three replicates per treatment ). levels of the hormone injection of gala...

current interests towards lowering fat content in food products and producing healthier and safer foods, have convinced ice cream manufacturers to substitute milk fat in ice cream with either carbohydrate or protein based fat replacers. in the present work, reduced-fat ice cream (5% fat) was produced using milk protein concentrate (65%) and inulin as fat replacers (0, 2 and 4%) as well as two t...

Milk is composed of a complex mixture of lipids, proteins, carbohydrates and various vitamins and minerals as a source of nutrition for young mammals. The composition of milk varies between individuals, with lipid composition in particular being highly heritable. Recent reports have highlighted a region of bovine chromosome 27 harbouring variants affecting milk fat percentage and fatty acid con...

It has been suggested that milk fat, due to its content of saturated fatty acids, may have a thrombogenic effect. In the present study the fatty acid profile of milk fat was modified by changing the feeding regimens of cows and the effect on haemostatic variables of a diet containing the modified milk fat (M) was compared with that of a diet containing milk fat of typical Danish composition (D)...

Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gen...

fifty six holstein lactating cows (71 days in milk; 35 kg/day milk production) were employed in a complete block randomized design of repeated measurements. cows were randomly allocated to two treatments based on their parity. cows in group 1 were fed a balanced total mixed ration (600 g concentrate /kg dm and 400 g forages /kg dm) with 50 g rumen protected methionine (rpm) per head per day (me...
