The objective of the study was to compare 305-day lactation milk yield in first and second lactations and selected fertility traits (number of services per conception, service period (days between first and last insemination), age at insemination and calving, gestation length, calving to conception period, calving interval period) in 2620 conventionally and automatically milked Polish Holstein-Friesian

Legumes are important protein source in human and animal nutrition. The experiment was performed on 32 weaned piglets divided into four groups. Animals were fed cereal-based diets with 109 g/kg of soybean meal and 150 g/kg of raw (LLR) or micronized (LLM) blue sweet lupin seeds or diets without soybean meal and with 300 g/kg of raw (HLR) or micronized (HLM) lupin seeds for 21 days. At the end of experiment

In weaned piglet diets, about 20% of the total protein and amino acids (AA) comes from the inclusion of sorghum or yellow corn. Therefore, the fraction of digestible amino acids of these ingredients is important for diet formulations. The ileal-cannulated pig model is not used in younger pigs due to difficulties related to implanting T-cannula in the distal ileum and possible subsequent problems. Thus

A major cost component in livestock production is feed, which suggests improved feed efficiency as a promising strategy to improve both competitiveness and environmental sustainability. This study has investigated the technical and economic efficiency of using two alternatives to the standard feeds in livestock production in Norway. Data was generated from two controlled feeding experiments involving

Heat stress is a great concern in the layer industry because it decreases egg production and egg quality. Orthosiphon stamineus extract (OE) has the potential to relieve heat stress, and rosmarinic acid (RA) is the main effective constituent of OE. However, the effects and mechanisms of OE and RA on heat stress in commercial laying hens remain unclear. In the current study, four hundred eighty 56 wk
