Ninety-six Yorkshire barrows and gilts were used in each of two experiments conducted in the spring-summer (exp. 1), and fall-winter (exp. 2) months, respectively, to evaluate 15% Tower rapeseed meal (RSM) as a partial replacement for soybean meal (SBM) on an isonitrogenous basis in corn-based diets for pigs from 23 to 91 kg body weight. At 91 kg, half the number of pigs in each dietary group were slaughtered. Then, three levels of protein (12, 14 and 16%) in both corn-SBM and corn-SBM-RSM diets were fed to the remaining pigs in each group up to a final body weight of 125 kg. The energy level in the RSM diets was not adjusted to equal that in the SBM diets. In the 23- to 91-kg gain period, average daily gain (ADG) (P < 0.01) and backfat (P < 0.05) were lower in the RSM-fed pigs compared to SBM-fed pigs only in exp. 2. From 91 to 125 kg body weight, ADG (P < 0.05), feed intake (P < 0.01) and backfat (P < 0.01) were lower for RSM-fed pigs only in exp. 2. The heavy weight pigs fed RSM diets had a lower (P < 0.01) dressing percentage than SBM fed pigs in exp. 1. Reduction of dietary protein from the 16% fed up to 91 kg body weight to either 14 or 12% in the 91- to 125-kg gain period did not affect performance.

An experiment was conducted during the late fall and winter months with 96 Yorkshire barrows and gilts to study the effects on pig performance of feeding corn-soybean meal (SBM) and lysine-HCl (0.1%) supplemented corn-SBM-Tower rapeseed meal (RSM) and corn-SBM-Candle RSM diets, in the form of mash (corn was medium-ground) and steam pellets. Average daily gain (ADG), feed intake, efficiency of feed conversion (feed to gain ratio, F/G) and carcass backfat thickness were measured in pigs reared from 23 kg to 91 kg liveweight. The energy level in the RSM diets was not adjusted to equal that in the corn-SBM diet. Pigs fed Tower RSM had a lower (P < 0.01) feed intake and backfat thickness and pigs fed Candle RSM had a lower (P < 0.01) ADG and feed intake and higher (P < 0.01) F/G compared to the pigs fed SBM. The pigs fed corn-SBM-Tower RSM had a higher (P < 0.01) ADG and feed intake and lower (P < 0.01) F/G ratio than those fed Candle RSM diets. Steam pelleting of the corn-SBM and corn-SBM-RSM diets improved ADG, feed intake and F/G of the pigs, with the effects being greatest for the RSM diets.

Two trials were carried out to assess the extent to which commercial, prepressed, solvent-extracted rapeseed meal could be substituted for soybean meal in starter concentrates for replacement calves. In trial I, rapeseed meal comprised 0, 8, 16, and 24% of the mixes, but still did not replace all of the soybean meal. When offered from 10 days of age, along with a "limited" milk feeding program and dry hay, there were no significant differences (P < 0.05) in feed consumption or average daily gain (ADG) to a final body weight of 114 kg. In trial II, rapeseed meal was used at three levels of replacement for protein from soybean meal: 0, 50, and 100%. This represented actual levels of rapeseed meal in the starter of 0, 14.5, and 29.8%. In addition, half the calves were fed a low-fat milk replacer and half a high-fat milk replacer. There was no significant interaction between milk replacers and the starter diets, nor did the milk replacers have any significant effect on feed intake or ADG over the whole trial to the final body weight of 114 kg. Replacement of all the soybean meal in the starter did result in a significant decrease in ADG because of lower feed intake per day. It is concluded that if a calf starter is to be pelletted it is possible to include up to 20% of rapeseed meal.

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.

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 was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p < 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p < 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.

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 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).

Two experiments were conducted to study the effects of supplementing broiler rations with a multiple cellulolytic enzymes system (Driselase) on the performance of chicks raised to 4 wk of age (exp. 1) and to 8 wk of age (exp. 2). Four broiler rations unsupplemented or supplemented with 0.03% Driselase were used in the study. One of the rations was based on soybean meal and wheat while the other three contained 20% rapeseed meal (produced from Regent, Candle and Turret cultivars of rapeseed) as a partial replacement for soybean meal. The results obtained in both experiments indicated a lack of response in body weight and feed conversion of the chicks to Driselase supplementation. In both experiments, the chicks receiving the rations containing rapeseed meal showed varying degrees of thyroid enlargement depending on the cultivar of rapeseed from which the meal was produced, with Turret meal causing the greatest increase in thyroid size.

The study was conducted to investigate the effects of Broussonetia papyrifera (BP) on growth performance, rumen fermentation, digestion and meat quality in Huanghuai white goats. Diets were developed with increasing doses of BP to replace maize silage [0% (control), 15% (BP15), 30% (BP30) and 45% (BP45)]. The design was completely randomized with 4 groups of 10 animals each, totalizing 40 animals (aged 150 ± 10 days and body weight of 25.32 ± 0.52 kg). Final body weight, average daily gain and average daily feed intake increased (linear and quadratic, P &lt; 0.05) as BP increased in the diet. The highest body weight and average daily gain were seen in the BP30 group. Feed conversion ratio also improved significantly (linear and quadratic, P &lt; 0.05) with the increasing level of BP. Although the concentration of microbial protein (MCP) in a linear (P = 0.0028) and quadratic (P = 0.0035) fashion with increasing level of BP, however, NH<sub>3</sub>-N in a quadratic (P = 0.0841) fashion with increasing level of BP. Crude protein was increased with increasing BP in the diets (linear and quadratic, P &lt; 0.05). Nitrogen intake, urinary excretion nitrogen and nitrogen retention were significantly improved (linear and quadratic, P &lt; 0.05) with dietary BP addition in goats. Dietary BP supplementation increased pH (linear and quadratic, P &lt; 0.05) and tended to reduce L* (lightness) (linear and quadratic, P &lt; 0.05). Additionally, the redness value of meat was significantly improved by BP addition (linear and quadratic, P &lt; 0.05). The inclusion of BP in the goat diet promotes growth and increases the digestibility of crude protein in addition to improving the meat colour and rumen fermentation.
