Was evaluated the pattern of growth among females and males of tambaqui by Gompertz nonlinear regression model. Five traits of economic importance were measured on 145 animals during the three years, totaling 981 morphometric data analyzed. Different curves were adjusted between males and females for body weight, height and head length and only one curve was adjusted to the width and body lengt...
Growth and carcass measurements were made on 2,411 Hereford steers slaughtered at a constant weight from a designed reference sire program involving 137 sires. A second data set consisted of ultrasound measures of backfat (USFAT) and longissimus muscle area (USREA) from 3,482 yearling Hereford cattle representing 441 sires. Restricted maximum likelihood procedures were used to estimate genetic ...
Growth performance and meat quality traits of 24 Massese suckling lambs reared up to 69 days age in different farming systems were evaluated. Three groups considered: stall (S) indoors fed concentrate hay; pasture (P) outdoor semi free-range (F) during the night at day, concentrate, hay herbage. The remained constantly with their dams for whole period, having thus always access mothers’ milk. A...
Live measurements of weight, height, length, girth, fat depth, stifleand hip-width were obtained prior to slaughter to develop prediction equations for carcass traits. The animals were boned out after slaughter and comprised 182 steers from the Southern Crossbreeding Program (progeny from Hereford cows crossed with seven sire breeds: Angus, Belgian Blue, Hereford, Jersey, Limousin, South Devon ...
Appetite-related neuropeptides proopiomelanocortin (POMC) and Neuropeptide Y (NPY) are essential for regulating feeding behavior and energy homeostasis. The objective of this study was to evaluate the effects of variants in POMC and NPY genes on growth, carcass and meat quality traits in rabbits. A total of six SNPs were identified for POMC (n = 2) and NPY (n = 4) genes by direct sequencing. Th...
Aim: The objective of this study was to evaluate the effects of introducing Sugar Beet bulb as a cheap substitute for grains in rations formulated for sheep fattening. Materials and Methods: This trial was conducted at the Experimental unit of Rural Development and extension center, Faculty of animal production, University of Gezira. Twenty four Sudanese desert lambs (Ashgur ecotype) were purch...
The objective of this experiment was to compare the effects of belt grill and Open Hearth electric broiler cookery on palatability and cooking traits of longissimus steaks. The longissimus thoracis from carcasses of grain-fed steers or heifers was used. Duplicate measurements were made for Warner-Bratzler shear force at 3 and at 14 d after slaughter (n = 180) and trained sensory evaluation at 1...
little scientific information is available that has evaluated safflower (carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. the objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (tmrs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. two consecutive trials were conducted us...
Abstract The aims of this study were to determine the prevalence carcass lesions in slaughtered pigs and quantify their relationships with different animal characteristics, pre-slaughter factors, blood measurements, performance indices, composition meat quality traits. Data was recorded for 30 journeys referring 1080 market-weight that originated from 15 commercial small-scale finishing farms. ...
