Turkish Journal of Veterinary & Animal Sciences

Seventeen Eastern Anatolian Red (EAR) bulls at 20 months of age were divided into 2 treatment groups and fed for either 168 days (S) or 210 days (L). Initial and final weights were not significantly different. While bulls in the L group had the highest total weight gain (149.0 vs. 177.2 kg), feed efficiency ratio was superior for the cattle fed for 168 days. Carcass weight, spleen and front + hind feet weights as a percentage of slaughter weight, weight of kidney fat, percentage of kidney, pelvic, and heart fat, and yield grade all increased (P < 0.05) with feeding time. Bulls in the L group received a higher (P < 0.05) panel rating for juiciness, and the panel juiciness score was closely associated with tenderness measurements such as panel tenderness score, Warner Bratzler shear force value, and number of chews before swallowing. It is concluded that duration of finishing significantly influenced carcass, slaughter, and organoleptic beef quality traits of young EAR bulls.

The Effects Of Feed Restriction On Performance And Carcass Composition Of Broilers In Finisher Period, Ergi̇n Öztürk, Musa Sarica

Turkish Journal of Veterinary & Animal Sciences

In this experiment, feed restriction was carried out on 1200 Ross broilers from days 35 to 42 and from days 42 to 49 days in order to determine the effects of feed restriction on performance and carcass traits. The birds consumed either a conventional finisher diet ad libitum, or a finisher diet reduced by 5, 10, 15 or 20%. While there were no changes in dressing percentage, thigh weight, chest weight, wing weight, back weight or feed utilization ratio as a result of feed restriction carried out during the 6th week, the abdominal fat weight, live weight and edible organ' …

Low Protein Rations Halve Bacon Pig Profits, N W. Godfrey

Journal of the Department of Agriculture, Western Australia, Series 4

For many years the department of agriculture has recommended that pig producers include meat meal or other protein concentrate in pig rations based on cereal grains. However, it is still common for pigs to be raised on cereal grains with little or no protein added.

Recent trials at the Department of Agriculture's Medina Pig Research Station have demonstrated the losses which can result from feeding pigs on low-protein cereal rations.

Beef Marketing As A Guide To Production Techniques, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

Until about a year ago beef was in strong demand. Almost anything was marketable at favourable prices and good profits could be made even if the production process was wasteful in some respects.

Now the tide has turned. The demand for beef is weak, prices are low and some types of beef are virtually unsaleable. Now more than ever it is important to look critically at the factors which affect beef quality and to seek ways of reducing waste in both feed used and end products marketed.

This article examines production and marketing of beef and points out some inadequacies …
