“…In addition, the growth traits and BF were influenced by the interaction of sex with RFI or RWI class. The difference observed between sexes for carcass traits agrees with the literature, showing a smaller REA and greater BF in females compared to males [ 10 , 36 , 37 ]. The differences in carcass traits between sexes can be explained by the fact that males have a higher anabolic rate of muscle tissue deposition than females, in addition to late adipose tissue deposition [ 38 , 39 ].…”

Feed and water efficiency are important traits to improve beef cattle production’s economic and environmental sustainability. This study evaluated residual feed intake (RFI) and residual water intake (RWI) and their relationship with performance, ingestive behavior, and carcass traits in Caracu beef cattle. The data were analyzed using a generalized linear model with least squares means. The ingestive behavior, performance, and carcass traits were influenced by sex (p < 0.05). Males showed higher dry matter intake (DMI), average daily gain (ADG), mid-test metabolic weight (BW0.75), rib eye area, and rump fat thickness than females, besides spending more time drinking and eating. Low RFI animals exhibited higher DMI than high RFI animals. Low RWI animals ingested 3.89 L/d of water further than high RWI animals. The interaction between sex and RWI influenced the DMI, BW0.75, and backfat thickness. The ingestive behavior of low and high RFI animals was similar, although high RWI animals visited a smaller number of drinkers than low RWI animals. Water intake positively affects productive efficiency, and the combined use of RWI and RFI may help improve the selection of more efficient animals contributing to reducing the costs of beef cattle production and improving environmental sustainability.

“…Similarly to these results, Lage et al (2012; data not included) reported in crossbred Zebu cattle that gender had no effect (P > 0.05) on performance, intake, digestibility of DM and all nutrients evaluated, feed efficiency, or carcass characteristics. With respect to gender, there was no difference in growth, diet OMD, or carcass and slaughter characteristics.…”

Quantitative meta-analysis was run on 108 publications featuring 116 experiments and 399 treatments dealing with the effect of trough or pasture feeding environment (FE) on ruminant performances. The objective was to compare the effect of trough or pasture FE on ADG, diet OM digestibility (OMD), various carcass characteristics, and the interaction between FE and complementation modalities. Live weight was adjusted to compare results between species. Results showed that trough-fed animals had higher ADG (+17.89%; P < 0.001), hot carcass yield (HYield; + 2.47%; P < 0.001) and carcass fat content (+ 24.87%; P < 0.001) than pasture-fed animals but lower carcass muscle and bone percentages (-1.60% [P = 0.010] and -7.63% [P = 0.003], respectively). Feeding environment had no effect on diet OMD (P = 0.818), but the number of observations was low. After considering the addition or not of concentrate in the diet (addiCO), FE effect persisted on ADG (P = 0.024) and carcass fat content (P = 0.027) but not on HYield (P = 0.078) or muscle and bone percentages (P = 0.119 and P = 0.581, respectively). After considering the nature of the concentrate (natCO), FE effect persisted on ADG (P < 0.001) and HYield (P = 0.004). Considering the percentage of concentrate in the diet (PCO) erased FE effect on ADG (P = 0.891) and HYield (P = 0.128). In contrast, considering the quantity of concentrate(QCO) erased FE effect on ADG (P = 0.084) but not on HYield (P = 0.006) or on carcass fat and muscle contents (P = 0.040 and P = 0.040, respectively) although the FE effect on carcass bone content persisted (P = 0.550). Animal species and physiological stage had no effect on any of the variables studied (P > 0.05) but experiment did (P ≤ 0.001). The increase in ADG was positively correlated to HYield in cattle (P = 0.002) and small ruminants (P = 0.003) and positively linked to carcass fat content (P = 0.007) but not carcass muscle content, which actually decreased (P = 0.001). Overall, this meta-analysis confirmed previous reports of FE effects and revealed how the differences generally reported result from a confounding effect of FE and nature of the diet. Indeed, in most of the studies used, trough-fed animals were supplemented with concentrate whereas pasture-fed animals were not. This research also highlighted the fact that pasture-fed animals have the potential to achieve the same performances as trough-fed animals when fed a similar diet.

This study aimed to evaluate differences in efficiency of feed utilization between young Nellore males and females by comparing growth traits, feed intake, blood parameters, and ingestive behavior of the animals. Data from 768 Nellore males and females that participated in eight performance tests for individual feed intake evaluation were used. Performance and feed efficiency measures, efficiency-related hematological, metabolic and hormonal variables, and data regarding ingestive behavior were collected. Feed efficiency measures were defined by the relationship between performance and feed intake. Data were analyzed using mixed models that included the fixed effects of sex, herd, and the covariate age within sex and the random effects of facility within year, year, and residual. Significant differences between males and females were observed for traits related to weight gain and feed intake. Although individual dynamics of feed efficiency measures differed between males and females, no significant differences in residual feed intake, feed efficiency, or relative growth rate were observed between sexes. Significant differences between sexes were found for platelets, red blood cells, hemoglobin, creatinine, glucose, urea, triglycerides, insulin, cortisol, and IGF-I. Females spent more time feeding and less time ruminating when compared to males. However, males exhibited higher feeding efficiency and lower rumination efficiency than females. Growing Nellore males and females are efficient in feed utilization, and the differences in blood variables observed are probably due to differences in body size and feed intake. Males spend less time eating, consume more food, and spend more time ruminating than females.
