Introduction Even though many of the cattle finished in the United States are fed in large feedlots there are still many small finishing operations that lack the equipment and facilities of commercial feedlots and there are individuals that have an interest in fattening their own beef; 4-H projects or locker beef are prime examples. When finishing cattle, the nutritional requirements do not var...

The objectives of this study were to investigate the effects of feeding barley naturally contaminated with Fusarium mycotoxins on growth performance, vulva swelling, and digestibility of dry matter, organic matter, and crude protein of gilts and the recovery of gilts fed normal diets immediately after the exposure to contaminated diets by measuring growth performance and vulva swelling. In Exp....

The objectives of this study were to examine the impact of corn- or wheat-based dried distillers grains with solubles (CDDGS or WDDGS) on enteric methane (CH4) emissions from growing beef cattle and determine if the oil in CDDGS was responsible for any response observed. Effects of CDDGS or WDDGS on total N excretion and partitioning between urine and fecal N were also examined in this replicat...

The effects of the carbohydrate composition of finishing diet (fed from 80 to 107 kg of body weight) and the length of pre-slaughter fasting on pork quality were studied in a 2 × 2 factorial experiment with 80 crossbred pigs. The control finishing diet was based on barley and soybean meal, and the fibrous finishing diet was based on barley, barley fibre, faba beans, and rapeseed cake. These die...

Indigestible neutral detergent fibers (iNDF) accurately predict forage digestibility when measured in situ. The objective of this study was to determine the effects of rumen incubation times on the estimated concentrations of iNDF for four forages (alfalfa hay, corn silage, wheat straw and orchard grass), four concentrates (barley grain, soybean meal, beet pulp and wheat bran) and two ...

BACKGROUND Growth in normal and malignant tissues has been linked to hyperinsulinemia and insulin-like growth factors (IGFs). We hypothesized that IGF and IGF-binding protein (IGFBP) responses may be acutely affected by differences in the glycemic index (GI) of foods. OBJECTIVE We compared the postprandial responses of IGFs and IGFBP to 2 foods of similar macronutrient composition but with gr...

Producers and consumers perceive that group rearing of slaughter pigs in deep bedded hoop barns is more welfare-friendly for pigs and produces pork with more desirable eating quality compared to conventional systems. However, little research supports this perception. Our objectives in two separate experiments were to evaluate the effects of housing system on pig welfare, meat quality, growth of...

The distillery sector is among the biggest industrial water user in United Kingdom (UK) and simultaneously delivers valuable by-products traditionally used for cattle feed, but recent years increasingly bioenergy generation. Our research provides new insight into these two aspects of alcohol production by 1) presenting first scarcity footprint Scottish single malt whisky, 2) comparing potential...

Metabolizable protein (MP) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources. Effects on production efficiency and N utilization of early post-partum dairy cows were determined. Forty-two multiparous and 16 primiparous Holstein cows were assigned to the diets in a randomized complete block design immediately after part...
