Sex Identification. The sex of the animals from which meat is produced is important for a few practical reasons. For beef production, in particular, carcass and meat quality traits are usually better in steers than in heifers and meat from steers is better valued. Information provided on close-out sheets included start and end date, cattle per pen, sex, housing type, days on feed, initial and sale BW, feed efficiency (FE), percentage of concentrate, ADG, percentage death loss, feed cost and total cost/), percentage of concentrate, ADG, percentage death loss, feed cost and total cost/ kg of BW gain, breakeven sale price, non-feed variable cost, non-feed fixed Cited by: A study was conducted on 50 steers ( ± 4 kg initial body weight, 3 years of age) to assess effects of days in feedlot on performance, carcass characteristics and meat quality of Tanzania. Re-sults indicate that performance and profitability of cattle feeding are rather complex and are affected by housing type, season, initial BW, concentrate level, sex, and pen cattle population.
The objective of this study was to evaluate the effect of castration on carcass and meat quality traits of Nellore cattle harvested after 0, or days on feed. INTRODUCTION. Optimum slaughter age to obtain maximum net return and desired meat quality may differ depending on castration age, gender, nutrition, and genetics, together with economic factors such as feed costs and carcass prices (Mark et al., ; Pyatt et al., ).Knight et al. (a) studied different castration and slaughter ages in grazing crossbred beef animals and proposed Cited by: In beef cattle, low vitamin A in the diet does not affect average daily gain (ADG), average daily dry matter intake (DMI), or gain to feed ratio (G:F); however, quality grade tends to be greater. Human sex hormones have a dramatic impact upon bone growth, remodeling, and maintenance during each life stage. With this understanding and knowledge a clear picture is painted regarding the importance of estrogens and androgens in all ages of men and women for the healthy maintenance of bone.
The effect of GnRH vaccination on performance, carcass, and meat quality and hormonal the same effect is also observed in GnRH vaccinated GI and BA and which hormonal factors cause this sudden increase in feed intake. Carcass and meat quality are also affected by GnRH vaccination. have synergistic effects upon growth performance in both Cited by: The lb cattle consumed 32% less total feed per group and required 87 fewer days to reach slaughter weights than 1,lb cattle. Bulls had a slightly lower (P steer by: Request PDF | Influence of animal temperament on stress responsiveness on the carcass quality and beef tenderness of feedlot cattle | Three groups of steers (A, B, C) were used to study the effect. Anabolic agents used in beef cattle result in increased feed intake, daily weight gain, and carcass lean proportion, and decreased F:G. 93,94 However, when administered after castration, manufactured anabolic agents, exogenous androgens or/and estrogens had negligible effects on growth performance in pigs in some studies, and positive Cited by:
