Abstract The objective of this study was to evaluate the effects of a synthetic analogue of the bovine appeasing pheromone (i.e. bovine appeasing substance; BAS) on growth and temperament of heifers. At weaning (d 0), 30 heifers (Aberdeen Angus ′ Nelore; 8 ± 1 mo) were stratified by body weight (199.8 ± 16 kg) and randomly assigned to receive a single dose of BAS (n = 15; SecureCattle; Nutricorp, Araras, SP, Brazil) or saline (CON; n = 15; saline 0.9% NaCl). Treatments (5 ml) were topically applied to the nuchal skin area of each animal on d0. Body weight was collected on d 0, 6, 15, 45, and 150. Chute score (1 to 5; 1 = calm, no movement; 5 = violent and continuous struggling) and chute entrance and exit score (1 to 3; 1 = slow; 3 = fast) were collected on d 0, 2, 6, 15, 45 and 150. Scores were averaged across 4 trained technicians. Data were analyzed using the MIXED procedure of SAS. Heifers assigned to BAS had greater (P < 0.01) average daily gain (ADG) than heifers assigned to CON treatment from d 6 to 15 (2.35 and 1.88 kg/d ± 0.16) and from d 15 to 45 (1.79 vs. 1.56 kg/d ± 0.08). Heifers assigned to BAS had lower (P < 0.01) chute entrance score on d 6, 15, and 45, and chute exit score on d 2 to 45 (P = 0.05) when compared to heifers assigned to CON. Additionally, heifers assigned to BAS tended (P = 0.08) to have lower chute score, from d 1 to 150 than heifers assigned to CON. The application of BAS at weaning improved heifers ADG, likely due to an improvement in temperament, suggesting that BAS application has calming effects in the beef cattle herd.

Abstract The objective of this study was to evaluate the effects of a synthetic analogue of the bovine appeasing pheromone (i.e. bovine appeasing substance; BAS) on growth and temperament of weaned calves grazing Capim-Marandú (Urochloa brizantha cv Marandú). At weaning (d 0), 86 calves (47 steers and 39 heifers; Aberdeen Angus ′ Nelore; 8 ± 1 mo) were stratified by body weight (197.9 ± 24.9 kg) and randomly assigned to receive a single dose of BAS (n = 43; SecureCattle; Nutricorp, Araras, SP, Brazil) or saline (CON; n = 43; saline 0.9% NaCl). Treatments (5 ml) were topically applied to the nuchal skin area of each animal on d0. Body weight was collected on d 0, 8, 15, 51 and 100. Chute score (1 to 5; 1 = calm, no movement; 5 = violent and continuous struggling) and chute entrance and exit scores (1 to 3; 1 = slow; 3 = fast) were collected on d 3, 8, 15, 51 and 100. Scores were averaged across 3 trained technicians. Data were analyzed using the MIXED procedure of SAS. Calves assigned to BAS treatment had greater (P < 0.01) average daily gain (ADG) from d 8 to 15 (0.158 and -0.284 kg/d ± 0.07). Calves assigned to BAS treatment tended (P = 0.10) to have lower chute entrance score on d 8 and 51 and had lower (P = 0.02) chute exit score on d 8 than calves assigned to CON treatment. Additionally, calves assigned to BAS treatment tended (P = 0.07) to have lower chute score on d 8 when compared to calves assigned to CON treatment. The application of BAS at weaning improved calf ADG and improved calf temperament as observed by chute score and chute entrance and exit scores, suggesting that BAS application has calming effects.

This experiment was conducted to evaluate the effects of corn or soybean hull incorporation into haylage-based diets on backgrounding calf performance and subsequent feedlot performance. Crossbred steers [n = 48, initial body weight (BW) = 303 ± 3.4 kg] were individually fed dietary treatments consisting of: (1) haylage [17.5% crude protein, dry matter (DM) basis; control], (2) haylage + 20% (DM basis) cracked corn, and (3) haylage + 20% (DM basis) soybean hulls during a 112-d backgrounding period. After the backgrounding period, all steers were adapted to a common high moisture corn-based finishing diet and fed until an ultrasound estimated backfat thickness of 7 mm was obtained. During the backgrounding period, steers fed cracked corn or soybean hulls had greater (P < 0.01) average daily gain, dry matter intake and gain:feed and lower (P = 0.05) plasma urea N as compared with controls. However, when finished on a common high-concentrate diet, steers previously fed cracked corn had greater (P < 0.08) average daily gain, final body weight, and longissimus muscle area than those fed soybean hulls, suggesting that source of supplemental energy during the backgrounding period may influence subsequent feedlot performance. Key words: Beef cattle, backgrounding, energy supplementation

Abstract Frequent measurements of body weight (BW) in livestock production systems are very important because they allow the assessment of growth development of animals. However, monitoring animal growth through traditional weighing scales is laborious and stressful for animals. Thus, the objectives of this study were to: 1) assess the predictive quality of an automated computer vision system used to predict BW and average daily gain (ADG) in beef cattle; and 2) compare different predictive approaches (Multiple Linear Regression: MLR, Least Absolute Shrinkage and Selection Operator: LASSO, Partial Least Squares: PLS, and Artificial Neutral Networks: ANN). A total of 234 images of Nellore beef cattle were collected during weaning, stocker and feedlot phase. Biometric body measurements from each animal were performed using 3D images captured with the Kinect® sensor, together with their respective BW acquired using an electronic scale. The biometric measurements were used as explanatory variables for each predictive model. Prediction quality was assessed using a leave-one-out cross-validation strategy. The ANN approach resulted on higher precision and accuracy for BW prediction compared to the other methods, with Root Mean Square Error of Prediction (RMSEP) and squared predictive correlation (r2) equal to: RMSEP = 8.6 kg and r2= 0.91 for weaning; RMSEP = 11.4 kg and r2= 0.79 for stocker, and RMSEP = 7.7 kg and r2= 0.92 for beginning of feedlot. The ANN was also superior for prediction of ADG for the weaning to stocker, weaning to beginning of feedlot, weaning to end of feedlot, stocker to beginning of feedlot and beginning to end of feedlot, with RMSEP: 0.02, 0.02, 0.03, 0.10 and 0.09 kg/d, and r2: 0.67, 0.85, 0.80, 0.51 and 0.82, respectively. Overall, results indicate that an automated computer vision system is a potential tool for real-time measurement of BW and ADG in beef cattle.

Abstract Synthetic appeasing pheromone (SAP) is expected to have a calming effect in cattle experiencing stressful situations, including weaning and feedlot arrival. In Exp. 1, 186 Bos indicus-influenced calves (73 heifers, 133 bulls) were weaned at 211 ± 1 d of age (d 0). Upon weaning, calves were ranked by sex and body weight (BW), and assigned to receive SAP (Nutricorp, Araras, SP, Brazil; n = 94) or water (CON; n = 92). Treatments (5 mL) were topically applied to the forehead of each animal. Calf BW was recorded on d 15 and 45. Calves that received SAP had greater (P < 0.01) average daily again (ADG) from d 0 to 15, and BW on d 15 compared with CON (0.94 vs. 0.73 kg/d and 249 vs. 246 kg; respectively). Calf ADG from d 15 to 45 was similar (P = 0.97) between treatments. Overall ADG and BW on d 45 were also greater in SAP vs. CON (0.36 vs. 0.29 kg/d and 251 vs. 248 kg; respectively). In Exp. 2, 140 Bos indicus-influenced bulls (~27 mo of age) were transported from a cow-calf ranch to a commercial feedlot (d -1), and maintained on a single pasture for 24 h. On d 0, bulls were ranked by BW and assigned to receive SAP (n = 70) or CON (n = 70) as in Exp. 1. Bulls receiving SAP had greater (P = 0.04) ADG from d 0 to 15, but less (P <0.01) ADG from d 15 to 45 compared to CON (1.65 vs. 1.45 kg/d and 1.42 vs. 1.65 kg/d; respectively). No other treatment effects were detected (P ≥ 0.18). Therefore, SAP administration to beef cattle at weaning or feedlot entry had immediate benefits to ADG, which were sustained for 45 d in weaned calves but not in feedlot cattle

Abstract This experiment evaluated the impacts of bovine appeasing substance (BAS) administration on performance, behavioral, and physiological responses of beef calves upon weaning. Eighty Angus-influenced calves (40 heifers, 40 steers) were weaned at 233 ± 2 d of age (d 0), ranked by age and body weight (BW), and assigned to receive BAS (Nutricorp, Araras, SP, Brazil; n = 40) or placebo (diethylene glycol monoethyl ether; CON; n = 40). Treatments (5 mL) were topically applied to the nuchal skin area of each animal. Within treatment, calves were allocated to 1 of 8 drylot pens (4 pens/treatment) and received a free-choice total mixed ration (TMR) from d 0 to 42, intake of which was assessed daily. On d 0, calves were fitted with a pedometer behind their right shoulder, and pedometer results were recorded weekly during the experiment (d 0 to 42) concurrently with full BW collection and temperament evaluation. Blood samples were collected on d 0, 3, 7, 14, 28, and 42, and hair samples were collected from the tail switch on d 0, 14, 28, and 42. Average daily gain from d 0 to 42 did not differ between treatments (P = 0.52), but was greater (P = 0.05) in BAS vs. CON calves from d 0 to 28. Intake of TMR was greater during the first week for BAS vs. CON calves (P = 0.05), and similar (P ≥ 0.44) from wk 2 to 6 (treatment × week; P = 0.08). Exit velocity was greater (P = 0.03) for CON vs. BAS calves on d 14 and tended (P = 0.08) to be greater for CON vs. BAS calves on d 7 (treatment × day; P = 0.04). Physical activity was greater for CON vs. BAS calves on d 1 (P &lt; 0.01), but greater (P = 0.01) in BAS vs. CON on d 2 (treatment × day; P = 0.01). Mean plasma concentrations of haptoglobin were greater (P = 0.03) in CON vs. BAS calves during the experiment. Hair cortisol concentrations were greater (P = 0.0 5) in CON vs. BAS calves on d 14 (treatment × day interaction; P = 0.03). Results from this experiment indicate BAS calves habituated to their environment more rapidly through increased physical activity, which facilitated a lessened stress response associated with weaning, and accelerated adaptation to a novel environment. This was manifested through improved TMR intake and BW gain during the initial period of the experiment. Collectively, results suggest use of BAS as a strategy to improve calf welfare and productivity upon weaning.

In Exp. 1, 186 Bos indicus-influenced calves (73 heifers, 133 bulls) were weaned at 211 ± 1 d of age (d 0). Upon weaning, calves were ranked by sex and body weight (BW), and assigned to receive BAS (Nutricorp, Araras, SP, Brazil; n = 94) or water (CON; n = 92). Treatments (5-mL) were topically applied to the forehead of each animal. Calf BW was recorded and samples of blood and tail-switch hair collected on d 0, 15, and 45. Calves that received BAS had greater (P &lt; 0.01) average daily again (ADG) from d 0 to 15, and BW on d 15 compared with CON. Overall ADG and BW on d 45 were also greater (P &lt; 0.05) in BAS vs. CON. Plasma concentrations of haptoglobin were less (P &lt; 0.01) in BAS vs. CON cattle on d 15, whereas cortisol concentrations in plasma and tail-switch hair did not differ between treatments (P &gt; 0.16). In Exp. 2, 140 B. indicus-influenced bulls (~27 mo of age) were transported from a cow-calf ranch to a commercial feedlot (d -1), and maintained on a single pasture for 24 h. On d 0, bulls were ranked by BW and assigned to receive BAS (n = 70) or CON (n = 70) as in Exp. 1. Bulls receiving BAS had greater (P = 0.04) ADG from d 0 to 15, but less (P &lt; 0.01) ADG from d 15 to 45 compared to CON. No other treatment effects were detected (P &gt; 0.18). Therefore, BAS administration to beef cattle at weaning or feedlot entry had immediate benefits to ADG, which were sustained for 45 d in weaned calves but not in feedlot cattle.

Twelve adult (10 months old) castrated Korean black goats, with an average initial body weight of 24.98 ± 3.7 kg, were used in this experiment to determine their maintenance energy requirements. Dry matter intakes (g/d, p = 0.945) were not affected by energy levels, but metabolic energy intake (kcal/d, p < 0.002) and average daily gain (g/d, p < 0.001) were significantly increased at higher energy levels. Nutrient digestibility was similar in the treatments, but crude fat digestibility increased with the addition of protective fat powder (p = 0.001). The energy required for fattening the castrated Korean black goats was estimated using the correlation between metabolic energy intake per dietary body weight and average daily gain per dietary body weight. The Y-axis intercept value was calculated to be 108.76 kcal/kg BW0.75 (p < 0.05, r2 = 0.6036), which was the metabolic energy requirement for maintaining the lives of the fattening Korean black goats. The estimated energy requirements of the black goat can improve specification techniques, such as the energy level and the amount of feed supply required for domestic black goats.
