two experiments were conducted to determine threonine (thr) requirements of two commercial strains, ross 308 and cobb 500, based on standardized ileal digestibility from 15 to 28d of age. basal diet consisted of wheat, triticale, and corn gluten meal was formulated according to quick chick (2006) to be adequate in all nutrients except for thr. incremental levels of supplemental thr were added t...

Forty steers and 40 heifers were allocated by gender and previous treatment to eight 12-acre Kentucky-31 tall fescue pastures. Each pasture was assigned to one of four supplement treatments to test the ability of either supplemental energy or two levels of supplemental escape protein to correct a possible ruminal imbalance of protein and energy found in high quality forages. Supplementation tre...

Two hundred twenty-eight crossbred steers (304 kg) were used in a 125-d comparative slaughter trial to evaluate the influence of level and source of supplemental fats on their feeding value for feedlot cattle. Dietary treatments consisted of a steam-rolled, barley-based finishing diet containing 1) no supplemental fat; 2) 4% yellow grease (YG); 3) 4% blended animal-vegetable fat (BVF); 4) 8% YG...

This experiment was conducted to investigate the effects of supplemental phytase in a corn-wheatsoybean meal basal diet on phosphorus (P) digestibility and performance of broiler chicks. 378 one-day old broiler chicks (Ross 308) were allocated to 3×3 factorial arrangements with three levels of phytase enzyme (0, 500 and 1000 FTU/kg) and three levels of non-phytate P (100, 80 and 60% of NRC requ...

While free amino acids are routinely used in feeds for terrestrial farm animals, it is – except for few aqua species – not commonly practiced in finfish and shrimp nutrition. Reasons for not using free amino acids are often related to doubts on the efficiency and availability of these ingredients. This paper discusses aspects on the availability and efficiency of supplemental amino acids in fis...

The aim of the present paper is to assess local residents' awareness of utilizing Supplemental Nutrition Assistance Program (SNAP) benefits to purchase fresh produce at local farmers' markets, and to determine internet use and media preferences of study participants prior to implementation of a social marketing campaign. A needs assessment was conducted to collect baseline data in an underserve...

Twenty-four lambs, averaging 29 kg, were used to determine the effect of supplemental dietary Fe on performance and Cu, P, Zn and Mn utilization. Treatments consisted of supplemental Fe at 0, 300, 600 or 1,200 mg/kg diet as ferrous carbonate. The basal diet contained 154 mg Fe/kg diet and consisted of 90% Coastal bermudagrass pellets, 9.45% group corn, .5% sodium chloride and .05% vitamin mix. ...

and Implication We tested the hypothesis that supplemental dietary vitamin D3 could be used to improve tenderness of pork. On the basis of elevation of blood calcium concentration and constant feed intake, we determined that 500,000 IU daily for three days before slaughter was the optimal dosage. This dosage resulted in no improvement in pork tenderness as based on two commonly used tenderness ...
