BACKGROUND The objective of this study was to investigate the association between average daily gain and the number of Lawsonia intracellularis bacteria in faeces of growing pigs with different levels of diarrhoea. METHODS A longitudinal field study (n = 150 pigs) was performed in a Danish herd from day 29 to 47 post weaning. Every third day all pigs were weighed, subjected to a clinical exam...

A simulation model was developed to predict corn crop residue yield and quality and intake and performance of growing cattle grazing cornstalks. The model is wholly deterministic and integrates the effects of weather, residue supply and animal components. Low temperatures increase animal energy requirements, whereas snow cover decreases residue available. Residual grain and leaf are calculated ...

Two experiments were conducted to determine the effect of varying dietary selenium (Se) levels and Se source on growing swine. In Exp. 1, seleniferous wheat and oats were used to formulate diets containing .47, 2.58, 5.60 or 8.40 micrograms/g organic Se. Dietary Se level had no effect on pig performance during the 6-wk experiment as measured by daily gain, daily feed intake or feed/gain. Blood ...

An investigation was conducted to evaluate the management effect of feeding triticale on the performance of crossbred feedlot cattle. Steers were weighed at fortnightly intervals until 83 days. Steers were weighed at 0700hr and fed upon (7 animals/treatment) at weighing on d 0, 20, 40, and 83 of the trial. Measurements were made of daily feed intake, average daily gain, body weight gain and fee...

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, gro...

In 40 Polish Landrace, 38 Polish Large White and 14 Pietrain fatteners the longissimus lumborum (LL) muscle fibres were characterized and LL quality indicators determined. The correlation was estimated between the LL fibres traits and daily live weight gain, muscle pH and texture parametres. Muscle fibres were identified as I, IIA and IIB types based upon their dehydrogenase (NADH) activity. Th...

1 Dry distillers grains improved gain and efficienicy relative to corn. Heifers supplemented daily consumed more hay and gained faster, but were not more efficient than those supplemented three times weekly. Summary An experiment was conducted with 120 crossbred heifers to determine the value of dry distillers grains (DDG) in high-forage diets, and to evaluate the effect of supplementing daily ...

The aim of this study was to evaluate the effect of a higher protein intake on lean body mass (LBM) gain in postmenopausal women practicing resistance exercise and compare it to the Recommended Dietary Allowance (RDA) recommendation. Twenty-three postmenopausal women (63.2 ± 7.8 years) were randomized into two groups. The group with higher protein intake (n = 11) (HP) received a dietary plan wi...
