Management factors affecting mortality, feed intake and feed conversion ratio of grow-finishing pigs.
The aim of this study was to determine the effect of animal management and farm facilities on total feed intake (TFI), feed conversion ratio (FCR) and mortality rate (MORT) of grower-finishing pigs. In total, 310 batches from 244 grower-finishing farms, consisting of 454 855 Pietrain sired pigs in six Spanish pig companies were used. Data collection consisted of a survey on management practices...
متن کاملFactors affecting the daily feed intake and feed conversion ratio of pigs in grow-finishing units: the case of a company
BACKGROUND The aim of this study was to use mathematical modeling to identify and quantify the main factors that affect daily feed intake (DFI) and feed conversion ratio (FCR) in grow-finishing (GF) pig units. We evaluated the production records of 93 GF farms between 2010 and 2013, linked to a company, working in a cooperative system, located in western Paraná State, Brazil. A total of 683 bat...
متن کاملFeed-conversion ratio of finisher pigs in the USA.
Although the feed-conversion ratio is recognized as a prominent indicator of profitability for pork producers, only 212 (50.7%) of 418 producers who were asked the feed-conversion ratio for finisher pigs provided a response during the USA National Animal Health Monitoring System 1995 National Swine Study. Of these, 126 (59.4%) producers furnished a feed-conversion ratio which they characterized...
متن کاملFeed intake pattern of group-housed growing-finishing pigs monitored using a computerized feed intake recording system.
The feed intake pattern and growth performance of boars, barrows, and gilts fed diets differing in lysine and protein content were measured on 120 crossbred pigs from 27 (SD 3.7) to 81.5 (SD 9.2) kg live weight. The pigs were housed in eight mixed-sex groups with five pigs of each sex in each group. They were fed from an electronic feed station that recorded individual meal sizes and the time a...
متن کاملInfluence of protein level, amino acid ratio and caloric density of the diet on feed intake and performance of pigs.
U N D E R conditions of ad libitum feeding, performance of swine is determined mainly by the voluntary feed consumption and the adequacy of nutrient levels in the diet. Recent emphasis has been on the establishment of optimum relationships between energy concentration and the levels of other nutrients in the diet. The relationship of source and concentration of dietary energy to level and quali...
