Because grains comprise the major portion of diets for finishing beef cattle, and grains contain little calcium, limestone is typically added to finishing diets at levels of .7 to more than 1% of the dry matter. Feedgrade limestone varies in quality and consistency, which could alter performance responses by finishing beef steers. Selection of superior sources of limestone and(or) treatment of ...

Introduction Load-carrying capacity of gears, especially the surface durability, is influenced by their tooth surface roughness in addition to their tooth profiles and tooth traces (Refs. 1 and 2). The harder the gears are, the smoother their tooth surfaces and the more accurately their tooth profiles should be finished in order to obtain high load-carrying capacity. Through research, the relat...

A genetically modified corn hybrid homozygous for the lpa1 allele, containing low phytate (LP), and its nearly isogenic equivalent hybrid (normal) were compared in two experiments with growing-finishing swine. In Exp. 1, 210 barrows (27 kg) were allotted to one of six dietary treatments with two corn hybrids (LP and normal) and three P feeding regimens. There were five replicate pens (seven pig...

AIMS The aims of this study were to evaluate the effect of various finishing and polishing procedures on the surface roughness of six different composite resin materials (Artemis Enamel, TPH Spectrum, Filtek A-110, Filtek Supreme Enamel, Solitaire 2, and Filtek P-60) as well as to evaluate the effectiveness of the surface sealant application (BisCover) on the surface roughness after finishing a...

Virtually all products that are finished require some pre-finishing procedure such as cleaning, stripping, or pickling. Without a properly cleaned surface, even the most expensive coating will fail to adhere or protect the workpiece. Depending on the process being performed, the degree of cleanliness will vary. Finishing operations such as phosphating, chromating, or electropolishing do not req...

Two studies were conducted to determine the effects of eliminating the supplemental vitamin and minerals during the last 30 d of finishing on pig performance. The first study was conducted in a controlled university environment and the second under field conditions. Deletion of vitamin and mineral supplements for the last 30 d of finishing had no effects on pig performance or general health of ...

background: in recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. objectives: this study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing chal lambs. methods: eighteen male ...

BACKGROUND Ready-to-use supplementary food (RUSF) is increasingly used as a component of food rations for adults with HIV. METHODS We undertook a qualitative study to evaluate the acceptability and use of peanut-based RUSF compared to corn-soy blend (CSB) among adults living with HIV in rural Haiti who had been enrolled in a prospective, randomized trial comparing the impact of those rations....

The objective of the trial was to study the relationship between the methane (CH4) production and the Cornell Net Carbohydrate and Protein System (CNCPS) carbohydrate fractions of feeds for cattle and the suitability of CNCPS carbohydrate fractions as the dietary variables in modeling the CH4 production in rumen fermentation. Forty-five rations for cattle with the concentrate/roughage ratios of...

Analyses of rats diurnal/nocturnal feeding behaviour were made according to the caloric density of the lipid ration. Adult male Sprague-Dawley rats were simultaneously offered three pure macronutrient diet rations: protein, carbohydrate, and lipid. The last was either kept isocaloric to protein and carbohydrate rations or was hypercaloric. Measurements of the food intake were recorded at 12-h i...
