Cattle weights can be highly variable and are influenced by many factors, including time of weighing, ambient temperature, feed intake, and cattle handling. A protocol of limit feeding has been in use since the 1980s that was designed to reduce variation in gut fill due to differences in intakes. Cattle are penned and fed a 50% hay, 50% wet corn gluten feed or grain diet (DM basis) at an estima...
The fatty acid composition of the intramuscular lipids of cattle, pigs and birds were determined relative to breed and feeding regime. The cattle included Yellow Cattle, Hereford and Japanese Black; pigs included Wild-boar, Touyuens and Yorkshires; the birds were Wild-birds, Jungle-fowl and broilers. The pen fed animals such as Japanese Black cattle and Yorkshire pigs had a higher amounts of ol...
I . After a preliminary period of z weeks indoor feeding on hay, two groups of wethers grazed either a timothy pasture or a ryegrass-dominant pasture for 12 weeks. The timothy was particularly low in sodium and chlorine. 2. Within a week of turning out, saliva sodium fell and potassium increased in the timothy group, and by the end of the experiment, the sodium:potassium ratio was 1.9: I . The ...
Sulfur (S) is a requisite part of the ruminant diet, but may sometimes be present in excess, leading to decreased animal performance and illness. In this experiment, 96 crossbred yearling steers (321 ± 29 kg BW) were used to determine the effects of dietary S concentration of a supplement fed to cattle on pasture and of the total diet in the finishing period. Steers were blocked by weight and a...
The effects of abrupt dietary transition on the faecal microbiota of forage-fed horses over a 3-week period were investigated. Yearling Thoroughbred fillies reared as a cohort were exclusively fed on either an ensiled conserved forage-grain diet ("Group A"; n = 6) or pasture ("Group B"; n = 6) for three weeks prior to the study. After the Day 0 faecal samples were collected, horses of Group A w...
The present study aimed to evaluate the effects of agroforestry system on the feeding behavior of dairy cows in the Brazilian Amazon region. Nineteen cross breed dairy cows (14.0±3.30 kg/d of milk yield and 450±40.1 kg body weight) were used. The following treatments were evaluated: A) animals were maintained in opened pasture of Brachiaria brizantha during all the day; B) animals were...
Effect of different feeding strategies on lactation performance of Holstein and Normande dairy cows.
The dairy farming systems of Western Europe are based on a simple feeding system composed of grazed and preserved grass, maize silage and concentrates in variable proportions. There is, nevertheless, a great diversity of feeding strategies between dairy farms. Over 5 years, we studied the direct and delayed effects of four feeding strategies on the lactation and reproduction performances of Hol...
OBJECTIVE To identify factors associated with excessive proportions of early fetal losses associated with mare reproductive loss syndrome in central Kentucky during 2001. DESIGN Case-control study. PROCEDURE Questionnaires were used to collect information on farm-, pasture-, and individual animal-level factors purportedly associated with mare reproductive loss syndrome. Data were collected ...
