13. Crossbreeding locally adapted hair sheep to improve productivity and meat quality
ABSTRACT: The use of lambs from crossing of local with specialized sheep breeds for meat production may lead to higher meat deposition and a smaller fat amount in the carcass, with a more adequate nutritional profile for human consumption. This study investigated the performance, carcass and meat characteristics of lambs from the Morada Nova and Santa Inês

14. Diagnostics of tuberculosis and differentiation of nonspecific tuberculin reactions in animals
Abstract Tuberculosis is a serious disease of humans and animals, caused by bacteria of the Mycobacterium genus. This leads to complications in the life of the sick person, and subsequently to death. The cattle, who have been diagnosed with this bacterium, are usually sent to the slaughter, with the result that their livestock is reduced. Mycobacteriosis is

15. Effects of Dietary Copper on Growth Performance, Slaughter Performance and Nutrient Content of Fecal in Growing Goslings from 28 to 70 Days of Age
ABSTRACT A dose-response experiment with four dietary copper concentrations (4.17, 8.17, 12.17 and 16.17 mg/kg) was conducted to estimate the growth performance, slaughter performance, nutrient content of fecal and liver copper concentrations of growing Goslings from 28 to 70 d of age. Two hundred healthy male Yangzhou geese with similar body weight were ran

16. Live Performance, Carcass, and Bone Quality Responses of Grower and Finisher Broilers to Dietary Metabolizable Energy Levels
ABSTRACT Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days of age. There are many evidences that broilers changed their feed intake capacity due to genetic selection, especially when good quality pellets are fed, which suggests that modern broiler strains may achieve good per

17. Effects of Transportation Distance, Slaughter Age, and Seasonal Factors on Total Losses in Broiler Chickens
ABSTRACT This study aimed at determining the total losses associated with the season, transportation distance, and slaughter age during the transportation of broilers from poultry farms to slaughterhouses in Turkey. All data and parameters were statistically analyzed and the change in total loss during transportation was evaluated by two-way analysis of vari

18. Effects of Guanidionoacetic Acid and Arginine Supplementation to Vegetable Diets Fed to Broiler Chickens Subjected to Heat Stress before Slaughter
ABSTRACT The objective of this study was to evaluate the supplementation of guanidinoacetic acid (GAA) and L-arginine (L-Arg) as creatine precursors to vegetable diets on the carcass yield and meat quality of broilers subjected to two days of heat stress before slaughter. A total of 1260 broiler chicks were distributed according to a completely randomized de

19. Effect of high energy intake on carcass composition and hypothalamic gene expression in Bos indicus heifers
ABSTRACT The objective of this study was to evaluate the effect of high or low energy intake on carcass composition and expression of hypothalamic genes related to the onset of puberty. Twenty-four prepubertal Nellore heifers, 18-20- months-old, with 275.3±18.0 kg body weight (BW), and 4.9±0.2 (1-9 scale) body condition score (BCS) were randomly assigned t

20. Breed and Sex Differences in the Gross Anatomy, Digesta pH and Histomorphology of the Gastrointestinal Tract of Gallus Gallus Domesticus
ABSTRACT A study was conducted to investigate the influence of breed and sex in the gross anatomy, digesta and histology of Ross 308 broiler and Venda chickens. Chickens were slaughtered at 90 days of age and the pH of the digestive organs was measured immediately after slaughter. The digestive organ weights and lengths of Ross 308 broiler and Venda chickens

21. Live weight, carcass, and meat evaluation of Nellore, Curraleiro Pé-Duro, and their crossbred products in Piauí State
ABSTRACT The objective of this study was to evaluate live weight and carcass traits, from birth to slaughter, and meat quality of Nellore (NEL), Curraleiro Pé-Duro (CPD), and crossbred (F1) products in the state of Piauí, Brazil. Progenies from CPD, NEL, and their F1 crossbred (½ NEL + ½ CPD), a total of 252, males and females, from birth to 24 months of

22. Volatile compounds in meat and meat products
Abstract Meaty flavor is composed of a few hundreds of volatile compounds, only minor part of which are responsible for the characteristic odor. It is developed as a result of multi-directional reactions proceeding between non-volatile precursors contained in raw meat under the influence of temperature. The volatile compounds are generated upon: Maillard rea

23. Dorper sheep utilizing feed resources efficiently: a Mediterranean case study
ABSTRACT The aim of the study was to determine the effect varying feeding systems would have on meat quality and production. The study looked at 45 Dorper lambs which were subjected to three different feeding protocols representing three alternate production systems: extensive grazing system (Group G), an intensive feedlot system being fed concentrate + alfa

24. Effect of Thermal Embryonic Manipulation on the Quality of Male and Female Broiler Meat Submitted to Thermal Stress Pre-Slaughter
ABSTRACT Adverse environmental conditions during rearing may negatively affect productivity and meat quality of the modern fast-growing broiler strains. Temperature manipulation during sensitive embryonic development periods may affect broilers' physiological responses to environmental conditions during rearing on commercial farms. The objective of this tria
