the present study was conducted to investigate effect of the fattening system and the duration of the fattening period on growth performance and carcass composition. in lori bakhtiary male lambs. sixty lambs were assigned to a factorial experiment of a completely randomized design comprised of two factors, including: fattening system (fs1: feedlot following weaning, and fs2: grazing on pasture ...

During growth and fattening, differences exist in the way nutrients are partitioned for deposition as fat and muscle protein. Knowledge of the partitioning of energy is of practical significance in the production of lean animals. In this review, emphasis will be placed on changes in fatty acid synthesis which occur during the growth and fattening of animals grown for meat, and on factors affect...

In the last decade considerable changes have taken place in the sheep industry in Hungary. Increasing numbers of sheep have been concentrated in newly established farms where intensive fattening methods have been practi­ sed. At present about 90 per cent of sheep are concentrated in large farms. Approximately 60-70 per cent of the total income of the sheep industry comes from the meat product i...

The aim of the study was presentation the differences in piglets sex proportion in litter and its effect weaning and fattening results. The study was carried out on 133 piglets belonging to 10 litters being progeny of PLW breeding sows and PL boars. Individual piglets growth rate from 1 to 28 day and also during fattening period were recorded. Obtained results were statisticaly analysed includi...

Skeletal abnormalities are most often used to describe defects in the arms or legs that are associated with genes or chromosomes, or that occur due to an event that happens during pregnancy. Spider lamb syndrome (SLS) is a congenital disorder in sheep breeding that is recognized by some deformities in skeletal system especially in the limbs.A dead day-old cross-breed white lamb with deformed li...

The purpose of the study was to determine the efficacy of Enterisol Ileitis vaccine administered orally in water against porcine proliferative enteropathy. For a comparison, two administration protocols were used for the vaccination: individual oral drench or via drinking water accessible to the herd. The efficacy of the vaccine was studied on breeding, commercial, and fattening swine farms. As...

As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices...

A Lamb wave-based crack detection method for aluminum plates health monitoring is developed in this paper. Piezoelectric disks are employed to actuate and capture the Lamb wave signals. The position of crack is assumed to be aligned with the sensor and actuator.  Extraction of high quality experimental results of lamb wave propagation in a plate-like structure is considerably complicated due to...

the data set used in this study contained 8793 records of lamb's longevity (days) from 320 sires and 2349 dams collected during 1989 to 2014, from the lori-bakhtiari flock at shooli station in shahrekord, iran. genetic parameters (partitioned into autosomal, sex-linked and maternal) and breeding values of cumulative lamb's longevity from birth up to yearling age (at 1, 2, 3, 6, 9 and ...
