Conditioned Flavor

Piglets can prefer flavors that are presented to pregnant sows, hence this study intended to estimate the effect of prenatal exposure of piglets to flavors on the intake of flavored creep feed and performance. Gestational sows were fed either a flavored (garlic or aniseed; n24) or an unflavored diet (n24) from days 90 to 114 of gestation. Their litters were offered either garlic, aniseed, or unflavored creep feed during the suckling period, and its intake was measured as well as animal’s final body weight (BW) and average daily gain (ADG). Data was analyzed taking into account the diet offered to both sows and piglets, as well as the interaction between these variables. As previous experiments have shown, flavor learning did not affect a piglet’s performance during the suckling period, finding no differences for creep feed intake, ADG, or BW according to diets (p > 0.05). Repeated exposure of piglets to previously learned flavors without clear post-ingestive benefits could nullify the strategies proposed. Moreover, milk and creep feed diets show a great reward contrast that may accelerate learning extinction. Results of the present and previous experiments suggest that current flavor continuity strategies that are proposed for pig production systems need to be reconsidered.

This experiment was determined the effect of weaning time on growth performance, rumen fermentation, and microbial bacterial community of lambs. Forty eight Hu lambs were randomly divided into 4 treatments. Control lambs were ewe-reared (ER), while others were weaned at d 10, 20, or 30 after birth (EW10, EW20 and EW30) and fed milk replacer artificially until d 60. All lambs had ad libitum access to same creep feed from d 15 to 90. Results showed that average daily gain, creep feed intake, final body weight, hot carcass and rumen weight of EW10, EW20 and EW30 were greater (P less than 0.05) than ER. The ammonia N concentration of EW20 and EW30 was greater (P less than 0.05) than EW10 and ER. Butyric acid in EW10 and EW20 was greater (P less than 0.05) than EW30 and ER. The richness and biodiversity of bacterial communities had no difference (P > 0.05). The predominated rumen bacterial composition in phyla level had no difference, but the minor phyla present, Proteobacteria, had difference. These results demonstrated that weaning time could improve the growth performance and rumen weight and slightly affect rumen fermentation. Weaning at d 10 was recommended to farmer to maintain prior rumen development and performance in lambs.

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.

Effect Of Feeding

The aim of this study was to investigate the effect of two dietary treatments (liquid creep feed (LCF) and dry creep feed (DCF)) offered during the suckling period on feed disappearance, number of eaters, and intestinal enzymatic development at weaning in an on-farm study with 347 piglets. Piglets were allocated to either the DCF or LCF treatment from day 10 to day 24 postpartum for 9 h a day. Red ferric oxide (1%) was added to the diet to categorize piglets into eating categories (good eaters, moderate eaters, or non-eaters) via faecal swabs. At weaning, 40 piglets were sampled for intestinal enzymatic development. The LCF treatment increased the dry matter disappearance from day 10–18 (p < 0.001). The percentage of good eaters, moderate eaters and non-eaters did not differ between treatments (p > 0.05). The DCF pigs displayed greater average daily gain (ADG) pre-weaning (p = 0.024), and a greater body weight (BW) at day 61 (p < 0.001). The activity of lactase, maltase and sucrase in the proximal part of the small intestine were greatest (p < 0.001) in the DCF pigs.

Abstract This study was conducted with the objective of evaluating the performance, carcass and meat characteristics of castrated and intact Dorper male lambs slaughtered at three different body condition scores. Thirty-five lambs, approximately 3 months old, 21.6 ± 4.0 kg of body weight and 3.1 ± 0.5 of body condition score (BCS), were used. The BCS scale used varied from 1.0 (very thin) to 5.0 (very fat). Four weeks prior to the experiment, 17 lambs were castrated. Lambs were further divided into three groups, according to the criteria for slaughter: BCS of 3.5, 4.0 and 4.5. All animals received the same diet. BCS were achieved after 27, 84 and 130 days in feedlot, respectively. There were no interactions (P > 0.05) between sexual conditions and slaughter criteria. Average daily gain of weight (ADG) was different (P < 0.05) for the three BCS (average of 0.263). However, final body weight (28.6 ± 1.7; 42.7 ± 1.8 and 56.8 ± 1.7 kg) and back fat thickness (0.5 ± 0.5; 4.2 ± 0.5 and 7.3 ± 0.5 mm) were different (P < 0.05) among BCS criteria, panelists found that meats from lambs slaughtered with greater fat content were less (P < 0.05) desirable. We can conclude by the performance and meat results that it is better to slaughter Dorper lambs with BCS with no more than 4.0, or 4.2 mm of back fat cover, and for the best acceptability of the meat the lambs should be castrated.

The objective of this experiment was to evaluate the effects of metabolizable energy (ME) levels in diets with high digestible lysine concentration on performance, carcass traits, and meat quality of barrows from 95 to 158 days of age. Eighty commercial hybrid barrows (50 ± 1.82 kg) selected for lean meat deposition, were assigned to four dietary treatments (3,150, 3,235, 3,320, and 3,400 kcal EM kg-1) in a randomized design with 10 replicate pens per treatment and two pigs per pen. From 95 to 116 days of age, we observed no effects of ME on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME levels (? = 5.79961 - 0.00096790X - r2 = 0.89). From 95 to 137 days of age, no effects of ME were observed on final body weight (FBW), average daily gain (ADG), metabolizable energy intake (MEI), and feed conversion (F: G). Average daily feed intake (ADFI) decreased linearly with increasing ME (?= 6.1176 - 0.001X - r2= 0.97). From 95 to 158 days, of age no effects of ME were observed on FBW and ADG. Dietary ME influenced the ADFI and F: G, which decreased linearly with increasing ME concentrations (?= 8.12951 - 0.00149X - r2= 0.99; ?= 6.0914 - 0.001X - r² = 0.75, respectively). There was a linear increase in loin eye area (LEA) with increasing ME (? = - 29.851 + 0.0207 X - r² = 0.87). Backfat thickness, pH, and temperature, measured at different times after slaughter (0 min, 45 min, 3 h, and 24 h), were not affected by dietary ME. The level of ME also did not affect the meat quality parameters Color L*, Color a*, Color b*, Warner-Bratzler shear force, thaw water losses, cooking water losses, sum of water losses, intramuscular fat content, and TBARS. Diets with 3,400 kcal kg-1 ME, corresponding to 2.75, 2.57, and 2.31 g digestible lysine/Mcal of ME for pigs from 95 to 116, 116 to 137, and 95 to 158 days of age, respectively, resulted in best performance and carcass traits, without negative effects on meat quality.

 The aim of this study was to evaluate the replacement of Tifton 85 hay (Cynodon spp.) by maniçoba hay or silage (Manihot glaziovii Muell. Arg) on sheep intake and performance. Twenty-four male Santa Ines animals were used, with initial body weight of 19.77 ± 1.95 kg and average age of 160 days. The animals were distributed in three treatments (Tifton 85 hay-TH, Maniçoba hay-MH and Maniçoba silage-MS), arranged in a randomized blocks design, with 8 replicates per treatment. The feedlot period lasted for 71 days. The means of the variables were tested by Tukey’s test at 5% probability. Sheep fed MH presented higher dry matter intake (p > 0.05) than those fed TH (1.17 kg day-1 vs 1.06 kg day-1). Neutral detergent fiber intake was higher (p > 0.05) for MH-fed sheep (0.394 kg day-1) when compared to MS (0.340 kg day-1). The digestibility of total carbohydrates was higher (p > 0.05) for MH diet (0.71 g kg-1) than TH (0.67 g kg-1). The average daily gain and body weight at slaughter did not differ (p > 0.05) among treatments. Maniçoba hay or silage can replace Tifton 85 hay in sheep diets.

Abstract. A study was conducted to find out the effect of birth weight and sex on growth rate of piglets in pre-weaning period. A total of 466 piglets from 48 litters of multiparous sows (Landrace) were involved in the experiment. Using a clustering approach piglets were assigned into three birth weight groups (Heavy (H), Intermediate (I), Light (L)). For the analysis of growth performance, pigs were weighed every 7 days until weaning at 28 days of age and average daily gain (ADG) was calculated. During lactation, body weight of L piglets was 5.5-fold increased, whereas the increase in I and H piglets were only 4.7-fold and 3.4-fold, respectively. Piglets of L group were significantly lighter at all studied ages compared to piglets of I and H group. The highest ADG was noted in the second week for all three groups; thereafter it decreased in H and L piglets (24% and 17%, respectively). The average birth weight of piglets was positively and significantly correlated with body weight at days 7, 14, 21 and 28. Sex did not affect significantly the ADG of the investigated animals during the four weeks of lactation. The present results indicate that neither milk production after the second week of lactation nor consumption of creep feed are sufficient enough to cover nutrition needs of fast growing piglets. There’s still a lack of optimization of nutrition in pre-weaning period especially for heavier piglets with their higher growth potential.

The effects of four stocking rates (0.070, 0.093, 0.116 and 0.140m2/ bird) on the performance of two hybrids of commercial broilers were investigated. There were significant hybrid effects on initial and final body weights (P< 0.01) and on feed effici­ency (P <0.05) but not on average daily gain and feed consumption and mortality. Stocking effects which were not signi­ficant for initial body weight, feed efficiency and mortality were highly significant for final body weight, average daily gain and feed consumption, (P < 0.01). There were significant interactions bet­ween hybrid and stocking rate for average daily gain (P <0.01) and mortality (P < 0.05). It is suggested that in the humid tropics, the stocking rates of 0.116 and 0.140m2/ bird would be appropriate for rearing broilers. The results of the study also show­ed that different hybrids do vary on space requirements in respect • of certain produc­tion traits.

The current study was presented to conclude the influence of different ratio of pomegranate peel powder (PP) in feed of Karadi male lambs, they divided to 4 groups (0% as a control, 1% treatment 1, 2% treatment 2 and 4% as treatment 3), on scrotal circumference (SC), scrotum height (SH), body weight (BW) and blood serum testosterone concentration (T). In this study, sixteen (16) of Karadi male lambs used with 24.30 ± 0.40 kg weight and with 4-5 months old, all lambs have been randomly divided equally into four (4) groups and individually penned in a box for during 63 days. Results in our study showed that SC was significantly different and recorded higher 17.875±0.54 cm in group that fed on 1% PP, also SH recorded higher and significant different in group fed on 1% PP compared with other groups 10.000±0.32 cm. Average blood serum testosterone reduces in all groups compared to control group that fed on 0% of PP (11.418±0.15 n.mol/L). Final body weight in our study had significantly different (P < 0.05) between groups, 1% PP recorded higher weight (34.9 ± 0.58) kg. Each average daily gain, total body gain and initial body weight had not significant different in all groups. Correlation coefficient between SC, SH, blood serum testosterone concentration and final BW computed and ranged between (-0.397 to + 0.914).

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.
