Drought is a frequent challenge to beef producers, and many operations would benefit from developing a better drought management plan. Producers should be constantly aware of their pasture conditions, stored forage supplies, animal feed demand, and long-term weather forecasts. The recent widespread drought across the Southern U.S. has led to large harvested forage shortages, depressed local cat...

Global consumption of poultry products, especially poultry meat, has consistently increased over the years, and this trend is expected to continue. Much of the increase in global demand for poultry products will be in developing countries. Such growth in the poultry industry is having a profound effect on the demand for feed and raw materials. However, it is also becoming clear that the require...

Physiologically horses have evolved to consume structural herbage, which takes a considerable amount longer to chew than cereals or processed feeds. Previous research has highlighted a significant reduction in chewing rates for concentrate feed As the principal stimulus to saliva production in the horse is mastication, the amount of saliva produced therefore can also be compromised when feeding...

In Exp. 1, individual performance and daily DMI was measured on 70 crossbred weaned calves during a 70-d period using a GrowSafe system (GrowSafe Systems Ltd., Airdrie, AB, Canada) at the University of Florida North Florida Research and Education Center Feed Efficiency Facility (FEF). Calves were fed a low-concentrate (LC) growing diet, blocked by weight and sex, and then randomly assigned to p...

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...

This study aims to determine the effect of conventional vegetable oil as feed additive, according soybean oil, coconut corn and efficiency, conversion ratio (FCR) fat content red tilapia. Feeding trial in this had used Completely randomized design (CRD), with 4 treatments repeated times. Red tilapia much 160 initial weight 25-40g/head, kept an aquarium a volume 20 dm3 density 2 ind./L, fed pell...

The aim of this study was to evaluate the effect of castration and slaughter age on performance and meat quality of Holstein bulls fed a high-concentrate diet. A total of 132 animals (116 ± 3.7 kg of BW and 97 ± 2.4 d of age) were randomly allocated in 6 pens using a 3 × 3 factorial arrangement of treatments. Three castration ages [bulls, animals castrated at 3 mo (CAS3), and animals castrated ...

This study reports a potential role that fish may play in the transmission of Mycobacterium ulcerans disease (Buruli ulcer). Fish found positive for M. ulcerans DNA all appear to feed on insects or plankton and are believed to concentrate M. ulcerans from this usual food source. These observations provide additional data supporting our previous hypothesis on sources of M. ulcerans and modes of ...
