Performance, ruminal changes, behaviour and welfare of growing heifers fed a concentrate diet with or without barley straw.
Two experiments were conducted to ascertain the effects of feeding an all-concentrate diet to growing heifers on performance, ruminal fermentation, behaviour and welfare. In experiment 1, eight tethered rumen fistulated Holstein heifers (143 ± 8.7 kg, initial BW) were used to study the effects of treatment on intake, ruminal changes and behaviour. In experiment 2, 48 Friesian female calves (ini...
متن کاملFeeding behavior and ruminal acidosis in beef cattle offered a total mixed ration or dietary components separately.
Eighty continental crossbred beef heifers (414.9 ± 37.9 kg of BW), 16 of which were ruminally cannulated, were used in a 52-d experiment with a generalized randomized block design, to assess if self-selection of dietary ingredients modulates ruminal pH and improves rumen function of feedlot finishing cattle. Treatments were total mixed ration [TMR; 85% barley grain (BG), 10% corn silage (CS), 5...
متن کاملPerformance and meat quality of beef steers fed corn-based or bread by-product-based diets.
A feeding trial was conducted with beef breed steers (120) to determine the effects of substituting bread by-product (BBy) for whole shelled corn on performance and meat quality. Chemical analysis of each diet ingredient and in vitro rates of digestion from gas production of BBy and corn were determined to provide accurate information for diet evaluations using the 1996 Beef NRC Model Level 2. ...
متن کاملEffect of feeding method on intake and behaviour of individually reared beef heifers fed a concentrate diet from 115 to 185 kg of body weight.
A total of eight Simmental heifers (114 ± 3.2 days old and weighing 118 ± 3.8 kg BW) were used to study the effects of feeding method on intake and animal behaviour in a crossover design experiment. Treatments consisted of feeding concentrate and chopped barley straw as (1) choice (CH; concentrate and straw in separate feedbunks) or (2) total mixed ration (TMR; concentrate and straw in one feed...
متن کاملEffect of Forage Feeding Level on Performance, Meat Quality and Economic Costof Holstein Beef Calves Fed Organic Diet
The aim of this study was to compare conventional and organic diets in beef production. Thirty-two dairy beef calves were used in 4 treatments: organic diet with three levels of forage [70% of organic diet with high amount of forage (ORH), 55% of organic diet with medium amount of forage (ORM), 38% of organic diet with low amount of forage(ORL)] and conventional diet (CON). The dry matter intak...
