The quality of nutrition of 22,249 men employed in Polish national economy was evaluated on the basis of own results and of literature data, obtained between years 1975-1984 in Poland. Energy content in the daily food ration (weighted mean) of the investigated men was 2879 kcal and was in agreement with the standard (lower level) recommended for men working moderately heavily. In the 14 publications considered, the mean value of energy content in the food ration fluctuated between 2495-3915 kcal/indiv. day. In the daily food ration (weighted mean), total protein content amounted to 93 g, with high participation of animal protein; it exceeded the recommended amount of protein. The amount of fat ingested daily by an average working man was 115 g, and exceeded the recommended fat intake by more than 20%. Evaluation of the daily food ration (weighted mean) from the standpoint of the groups of products showed that the daily intake of: a) meat, sausages and fish, 2) eggs and 3) fats, amounting to 292, 29.5 and 49 g, respectively, greatly exceeded that recommended by food standards, and accounted for 194, 177 and 141%, respectively, of the food allowance. In contrast, the mean daily intake of: 1) milk and its products, and 2) vegetables and fruits, was lowest, and accounted for 44 and 53%, respectively, of the food allowance.

Velvet bean is a native Indonesian legume containing L-dopa, yet it remains underutilized. The aim of this study was to analyze the effects of different types of tempe (soybean, velvet bean, and their combination) on cognitive function, brain histology, dopamine levels, and serum β-amyloid in rats, as well as to identify the parameters most influencing cognitive function, including brain mass and volume, hippocampal neuron count, and dopamine and β-amyloid levels. An experimental study was conducted using a completely randomized design with one factor: the protein source of diet.

This study aimed to evaluate the effect of autolyzed yeast (obtained from culture of Saccharomyces cerevisiae in sugarcane derivatives) supplementation on diet digestibility, feeding behavior, levels of blood metabolites associated with protein and energy metabolism, and performance of Dorper × Santa Ines lambs finished in feedlot. Twenty-four non-castrated male lambs with an average age of 4 months and a body weight (BW) of 19.49 ± 3.

Background: Ration composition may significantly impact the nutrient absorption, duodenal parameters, intestinal health and feed efficiency of animals.
Objectives: The objective of this study was to analyse the impact of concentrate- and forage-based diets on essential morphological parameters of the duodenum, including villus height, villus width, crypt depth and goblet cell density, in three different lamb breeds.
Methods: Forty-five lambs, aged between 2.

This study examined the effects of supplementing dairy cows with a mixture of essential oils on enteric CH emissions, apparent total-tract nutrient digestibility, N utilization, and lactational performance (production, components and efficiency). Thirty-two multiparous lactating Holstein cows were used in a randomized complete block design. Cows averaged (mean ± SD) 95 ± 15.

Decades of research have helped inform practices on how to care for calves, but little is known about how well these practices are adopted on commercial dairy farms. The primary aim of this study was to describe rearing practices of dairy calves in British Columbia, Canada. Measures of calf growth are sometimes used to assess success in calf rearing, so a secondary aim was to describe methods used to assess calf growth on these farms.
