Carnitine for lactating dairy cows
… of supplemental carnitine for lactating dairy cows. In the first experiment, carnitine (ca. 6 g/d) was administered into either the rumen or abomasum. Concentrations of carnitine in milk, plasma, liver, and urine increased similarly for both sites of carnitine administration. Milk yield and …

Impact of relocation on dairy cows
… the impact of relocation on lactating dairy cows. In experiment one, locomotion was scored on a 4-point scale where 1 = normal and 4 = lame. Cleanliness was scored on a 4-point scale where 1 = little or no manure visible and 4 = heavy plaques of manure on 3 body regions: udder, lower leg, and …

Increasing estrus expression in lactating dairy cows
… before inducing luteolysis or (2) exposing cows to estradiol cypionate (ECP) or testosterone propionate (TP) after luteolysis would increase occurrence and intensity of estrus. In experiment 1, cows (n = 154) were fitted with an AMS collar and a pressure-sensitive, rump-mounted device (HW) …

Effects of Feeding Leptaden to Dairy Cows
… harmful effects on the health of women or cows. On the basis of the lactogenic and galactagogue properties of the Leptaden, the research reported in this thesis was undertaken with the following objectives: 1. To determine the effects of feeding Leptaden to dairy cows on milk production and …

Urea-N Recycling in Lactating Dairy Cows
… microbial N flow. Eight mid-lactation Holstein cows were assigned to a repeated 4 x 4 Latin square. The diets were isoenergetic with RDP and RUP concentrations arranged in a factorial design (10.0 and 12.5% RDP and 5.6 and 8.1% RUP as a percentage of DM). The 10.0% RDP diets resulted in greater …

L-Carnitine Supplementation for Periparturient Dairy Cows
… and decreases liver lipid accumulation in dairy cows. In experiment 1, 8 mid-lactation cows were abomasally-infused with water or 20 g/d of L-carnitine in combination with ad libitum or restricted dry matter intake. Carnitine infusion increased in vitro fatty acid oxidation by liver slices and …

Niacin-lipid interactions in lactating dairy cows
Niacin-lipid interactions in lactating dairy cows were investigated. Treatments were: control, nicotinic acid (12 g/d), calcium salts of long chain fatty acids (3% diet dry matter), and calcium salts of fatty acids with nicotinic acid. Cows received treatment diets from week 2 to week 14 postpartum.

A digestion trial with two Holstein cows
… of a digestion trial made with two Holstein cows, one being feed maintenance ration plus protein, the other maintenance ration plus carbohydrate. The digestive co-efficient of both cows were about normal. The cow which received the maintenance ration plus B. Albumen digested 67.87% of whole …

Comparison of maternal performance of reciprocal crossbred cows
… performance of reciprocal two-breed cross cows between Angus, Herefords and Shorthorns was compared in 249 matings over a four year period. These cows were mated to bulls of the same three breeds to produce three-breed and baekcross calvea. Shorthorn x Angus cows (sire breed first) weaned …

Grazing and Feeding Management of Lactating Dairy Cows
… to determine time patterns of grazing between cows supplemented with different forms and amounts of corn. Also rumen fermentation parameters were measured in cows supplemented with two different types of corn. In study 2, milk yield was measured when grazing pasture was supplemented to …

Artificial Induction of Lactation in Nonbreeder Dairy Cows
Thirty-four cows (26 Holsteins and 8 Jerseys) were subjected to an estrous synchronization protocol administering 2 PGF2Æ Ã injections 11 d apart prior to beginning the lactation-induction protocol. Artificial induction of lactation yielded a 92% success rate for Holstein cows with success defined …
