A 5 x 5 Latin square design was used to determine the effects of restricted and ad libitum intake of diets containing wheat middlings on the site and extent of digestion compared to ad libitum intake of a corn-based diet and ad libitum intake of chopped alfalfa hay. Five ruminally and duodenally cannulated Angus steers (519 +/- 41.5 kg BW) were used to compare five dietary treatments. The five ...

Four experiments involving 16 pens of 8 to 10 crossbred steer calves each were conducted at Yuma, Arizona. Initial and final weights were approximately 170 and 275 kg, respectively. The experimental design was a 2 x 2 x 4 factorial replicated over 2 yr with main effects for season (summer, winter), diet (H = ground alfalfa hay, H + G = 50% ground alfalfa, 47.5% dry-rolled wheat and 2.5% molasse...

The objective was to determine the effect of forage quality on apparent total tract digestibility and ruminal fermentation in cattle versus sheep. Five yearling English crossbred (Hereford × Angus) steers (440.4 ± 35.6 kg of initial BW) and 5 yearling whiteface (Rambouillet × Columbia × Debouillet) wethers (44.4 ± 4.6 kg of initial BW), each fitted with a ruminal cannula, were randomly assigned...

Our study aimed at investigating the effect of feed supplementation, from weaning, with 3 sensory feed additives (FA1, FA2, and FA3) on feed preferences, feed intake, and growth of piglets. The FA1 contained extract of Stevia rebaudiana (10 to 20%), extract of high-saponin plants (5 to 10%), and excipients (70 to 85%), the FA2 was mainly composed of a natural extract of Citrus sinensis (60 to 8...

Normally innocuous forages are sporadically associated with hepatogenous photosensitization outbreaks at certain times of the year or when grown and harvested during unusual environmental conditions, such as periods of excessive rainfall. Allegations of livestock illness following consumption of such moldy hays are associated with clinical syndromes uncharacteristic of known forage-related dise...

A variety of measures including Relative Feed Value (RFV), Relative Feed Quality (RFQ) and Total Digestible Nutrients (TDN) have been used to set the value of alfalfa hay for sale. However, components or characteristics of alfalfa in addition to these measures may prove useful in determining the real market and feeding value of alfalfa compared to other feeds.

the effect of different levels of alfalfa hay and corn silage, in early lactation diet, on milk production and on milk components in holstein cows was investigated. fifteen holstein cows (37 ±10 dim) were taken in a completely randomized design experiment, lasting for 9 weeks. three levels of hay and corn silage namely: 1) 10% alfalfa -30% silage corn (diet 1), 2) 20% alfalfa -20% silage corn (...

Two experiments were conducted with Polypay ewes nursing twin lambs to evaluate the effects of supplementing fat (calcium salts of palm oil fatty acids or hydrogenated tallow) on ewe lactation. In Exp. 1, ewes were fed a 52% concentrate:48% hay-based diet (as-fed basis) consisting of alfalfa hay (n = 4), endophyte-free fescue hay (n = 4), or fescue hay with 3.7% fatty acids (n = 4) from d 4 to ...
