Commercial heifers (n = 120) were randomly assigned to 12 pens (10 heifers/pen) and fed one of four grain diets in combination with barley silage and vitamin premix. Treatments were 100% barley control, 100% triticale, 50% triticale 50% barley, 25% triticale 75% barley. Treatment differences were not significant (P > 0.05) for body weight (BW), average daily gain (ADG), feed intake (FI) and feed:gain (FG).ADG, FI and FG for the 100% triticale treatment were 1.24 kg d−1, 7.88 kg d−1 and 6.29 kg kg−1 respectively, while in the control they were 1.23 kg d−1, 8.03 kg d and 6.39 kg kg−1.

A total of eight 11-wk trials were conducted to evaluate the productivity and aggression at grouping of grower-finisher pigs [initial body weight (BW) = 31.8 ± 5.4 kg (mean ± SD), n = 2304] in two group size treatments (18 and 108 pigs pen-1). Pigs were housed on fully-slatted floors, provided one wet/dry feeder space for every nine pigs, and a floor space allowance of 0.76 m2 pig-1 in both group sizes. The level of aggression at grouping was recorded for 2 h starting 0, 24 and 48 h following grouping into small and large groups. Pigs were weighed on weeks 0, 2, 5, 7 and 11, and average daily gain (ADG) was obtained. Average daily feed intake (ADFI) was recorded during two periods (weeks 2 to 5 and 7 to 11). There was no difference in percentage of time spent on aggression between two group sizes up to 48 h following grouping. ADG for the entire 11-wk trial was affected (2%) by large group size (0.971 and 0.955 kg d-1 for groups of 18 and 108, respectively; P < 0.05). However, the greatest effect on ADG was observed during the first 2 wk following grouping (0.919 and 0.833 kg d-1 for groups of 18 and 108, respectively; P < 0.001). There were no significant effects due to group size on ADFI, feed efficiency, variability in final BW within a pen, carcass traits or mortality and morbidity (P > 0.05). In summary, the overall productivity and aggression at grouping did not differ substantially between group sizes of 18 and 108 pigs pen-1.

Five corn-soybean-based diets were formulated to contain 0, 15, 20, 25, or 30% raw peas and fed for 35 d to ninety-six 21-d-old pigs. Raw peas were included at the expense of corn and soybean meal. Increasing levels of raw peas depressed daily gain (P = 0.07), feed intake (P = 0.04) from days 21 to 56. Specifically, pigs fed diet with 25% peas had 19 and 25% lower average daily gain (ADG) and average daily feed intake (ADFI), respectively, than pigs fed the diet with 0% peas. The body weight (BW) was also linearly reduced (P = 0.10) on day 56. However, diets did not affect feed efficiency. Key words: Growth performance, peas, pig

The objective of this work was to evaluate performance, efficiency parameters and phenotypic correlations among measurements of energy efficiency of Nellore cattle selected for post weaning weight and classified according to residual feed intake, calculated by the difference between observed and predicted intake, based on average metabolic body weight and average daily gain. Thus, animals were classified within three groups: high (> mean + 0.5 standard deviation, less efficient); medium (±0.5 standard deviation of the mean); and low (< mean - 0.5 standard deviation, more efficient) residual feed intake. No differences were observed at initial and final body weights, average daily gain and dry matter intake among groups. Animals with low residual feed intake also had greater feed efficiency, feed conversion and partial efficiency of growth and did not differ from the other animals regarding to relative growth rate and Kleiber ratio. Residual feed intake was significantly correlated to feed efficiency (-0.25), feed conversion (0.25), partial efficiency of growth (-0.37) and dry matter intake (0.16) but it did not present significant correlation with body weight (0.04), average daily gain (-0.02), relative growth rate (-0.03) and Kleiber ratio (-0.05). Significant correlations were found between feed conversion and initial body weight (0.34) and average daily gain (-0.46). Partial efficiency of growth presented significant correlation with all other efficiency parameters analyzed. Residual feed intake has high potential in productive efficiency, when compared to the other energy efficiency measurements, being independent of growth and size of the animals.

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.

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

This study aimed to (1) investigate the effect of birth and weaning body weight (BW) on performance indicators of grow-finisher pigs and (2) estimate birth and weaning BW cut-off values in order to identify slow growing pigs (SGP). Pigs (n = 144) were classified as SMALL (0.9 ± 0.13 kg) or BIG (1.4 ± 0.20 kg) at birth and re-classified as SMALL (5.4 ± 1.6 kg) or BIG (6.3 ± 1.91 kg) at weaning. Individual BW was recorded bi-weekly, and feed intake was recorded on a daily basis. Average daily gain (ADG) and feed intake, feed conversion ratio (FCR) and days to target slaughter weight (TSW) were calculated. SMALL–SMALL pigs had lower ADG (p < 0.05) requiring 167.1 days (i.e., 14.2 extra days) to TSW (p < 0.05) compared with BIG pigs at birth and/or weaning. However, FCR was similar between groups (p > 0.05). Pigs weaned at <3.7 kg BW would likely be SGP. Pigs born at ≥1.1 kg BW or weaned at ≥6.4 kg BW are more likely to reach TSW at 22 weeks of age. The results suggest that birth BW might not be the best predictor for subsequent performance, as some small-born pigs were able to catch up with their bigger counterparts. The cut-off values identified could be used to design specific management and nutritional strategies for SGP.

Sixty-seven pigs were weaned at 5 wk of age and assigned to pens with either plastic-coated expanded metal or woven-wire floorings. The feet of each pig were examined at weaning and at the end of a 28-d starter period for soundness. Eleven gilts which had been on plastic-coated flooring and 12 gilts which had been on woven-wire flooring were moved at the end of the starter period to 1.2 × 1.2-m pens with the same floor types. These pigs were fed ad libitum until slaughter at 94 kg bodyweight. At weaning, the incidence of foot lesions was only 7%. Floor type did not have any significant (P > 0.05) effect on average daily gain, average daily feed intake or feed:gain ratios of pigs during the starter (8–22 kg), grower (22–55 kg) or finisher (55–94 kg) periods. Foot lesions were most severe (P < 0.01) in starter pigs which were penned on woven-wire flooring. There was also a tendency (P < 0.06) towards more severe hind-toe lesions in 94-kg gilts which were penned on woven-wire flooring. In general, the lateral digits of the feet of these gilts had more severe lesions (P < 0.01) than the medial digits. The severity of osteochondrosis of the condyles of the femur and humerus, of the articular cartilage of the proximal ulna and radius and of the distal ulnar physis were not significantly (P > 0.05) affected by floor type. The influence of floor type on the locomotory system appeared therefore to be confined to local foot abrasions and did not extend to the knee and elbow joints.

This study aimed to assess the performance, carcass traits, and non-carcass components of feedlot finished Texel crossbred lambs from different residual feed intake classes (RFI). Forty-seven uncastrated male Texel crossbred lambs (¾ Texel + ¼ Pantaneira) tested here were 4-month-old with an initial weight of 29.9 ± 5.5 kg. The lambs were confined for 70 days for individual dry matter intake (DMI) and average daily gain (ADG) assessment. The diet containing corn silage was provided as roughage, while the concentrate consisted of corn grain, soybean meal, urea, and mineral mixture with a 40:60 roughage to concentrate ratio and 76.34% total digestible nutrients (TDN). After confinement for 70 days, the lambs were slaughtered to assess carcass traits and non-carcass components. Based on the RFI, lambs were divided into three classes according to the standard deviation (sd): Positive RFI (inefficient, 0.5 above the mean), Negative RFI (efficient, 0.5 below the mean), and Medium RFI (intermediate). Classes with Negative (efficient) and Positive RFI (inefficient) showed no differences in ADG (0.321 vs 0.306 kg; P > 0.05). Dry matter intake (g d-1), and percentage of body weight (BW) differed significantly between the RFI classes (P < 0.05). Compared to lambs in the inefficient class, those in the efficient class (Negative RFI) showed a 9% reduction in DMI and had the same ADG. The lambs in either Positive or Negative RFI classes showed no weight differences between non-carcass components (P > 0.05). The RFI classes showed no differences in shrunk body weight, hot carcass weight, hot dressing, and weight of commercial cuts (P > 0.05). They showed no differences in neck, shoulder + shank, loin, rack, flank steak, rack cap off, and leg weights (P > 0.05). Our results indicate that improvement in feed efficiency, as a function of the RFI index, does not compromise performance and carcass traits of Texel crossbred lambs.

Phosphorus excretion may have a major impact on the environment if it is not managed properly. The success of management strategies for reducing P excretion of pigs is dependent partly on more accurate estimates of P requirements, specifically digestible instead of total P requirements. Performance and metabolism studies were conducted to determine digestible P requirements of grower pigs based on performance, plasma and bone P, and P excretion and retention variables, using 200 pigs (23 ± 0.9 kg) and 20 barrows (54 ± 3.1 kg), respectively. Pigs were fed one of five concentrations of dietary digestible P (0.19, 0.24, 0.33, 0.35, and 0.38%). Increasing digestible P quadratically increased average daily gain (ADG) (P < 0.01), feed intake (P < 0.05), and feed efficiency (P < 0.001). Barrows had a higher ADG than gilts (0.890 vs. 0.838 kg d-1; P < 0.05); however, digestible P requirement was higher for gilts than for barrows (6.92 vs. 6.17 g d-1 or 0.36 vs. 0.32% in diet; P < 0.05). In barrows, increasing digestible P intake quadratically increased P in plasma and urine (P < 0.01), and linearly increased P in faeces (P < 0.01), suggesting that P excretion depends on excess P intake. Using regression analysis, digestible P requirements were 6.45 g d-1 with ADG, 7.46 g d-1 with bone P, 6.01 g d-1 with plasma P, 3.61 g d-1 with urinary P, 5.86 g d-1 with retained P, and 5.11 g d-1 with retained N. Feeding P closer to pig requirements will reduce P excretion. Key words: Phosphorus, requirement, pig
