Abstract The objective of this experiment was to evaluate four levels of a natural vitamin E on lamb performance, blood metabolites, rumen metabolism and meat quality characteristics. Thirty-six male lambs (29.24 SD 2.54 kg Hampshire x Suffolk) were used in a completely randomized experimental design. Treatments consisted of dietary inclusion of Herbal E-50 (Nuproxa) at 0, 1, 2 and 3 g/kg dry matter (DM) for for 60 days in lambs that did not receive any additional source of vitamin E. A quadratic response was observed on daily gain, final body weight, feed conversion, intake blood cholesterol and glucose. The estimated optimal level of herbal E obtained of herbal E levels for average daily gain was 1.76 ± 0.10 g/kg and 1.84 ± 0.77 g/kg for feed conversion. Ruminal pH and the major volatile fatty acids were not affected by herbal E. A quadratic response was observed on blood cholesterol (P < 0.10) and glucose (P < 0.01). Dietary herbal E increased linearly counts of erythrocytes (P < 0.05), platelet (P < 0.10), proteins and globulins (P < 0.01) whereas the albumin/globulin ratio was linearly reduced (P < 0.01). Meat texture was improved (quadratic; P < 0.05) and the reducing/antioxidant capacity was improved linearly (P < 0.001) with herbal E. Redness measured at 7 d was also improved with herbal E (P < 0.05; lineal effect). The lamb performance can be improved with 1.8 g/kg Herbal E 50 in finishing lamb diets. The inclusion of herbal E feed plant additive improved the daily gain in finishing lambs, feed efficiency and improved meat oxidative stability.

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.

Calcium (Ca) propionate can be added to ruminant diets as a glucogenic substrate. However, due to its hypophagic effect, it is necessary to establish the optimal dose that can be used to replace grains in finishing diets for lambs. Therefore, the objective of this study was to assess the effect of four concentrations of Ca propionate in lamb diets on productive performance and rumen fermentation. Thirty two Hampshire x Suffolk lambs (23.82 ± 0.40 kg initial body weight), distributed in a completely randomized design, were given a diet with four concentrations of Ca propionate (g kg−1): 0, 10, 20 or 30 g, for 42 days. The results were tested for linear or quadratic responses. The final weight, average daily gain and feed: gain ratio showed quadratic responses (P ≤ 0.01). The optimal dose was established at 13.77 g kg−1 DM. Addition of Ca propionate did not affect variables related to rumen fermentation (pH, total volatile fatty acids, acetate, butyrate or rumen ammonia-N; P ≥ 0.05) . Nonetheless, glucose and propionate concentrations showed a quadratic response (P ≤ 0.05). The highest concentrations of propionate in rumen were observed with 15.14 g kg−1 DM. Results indicate that Ca propionate can be included in a dose of up to 13.77 g kg−1 DM in feedlot rations, to attain best lamb performance.

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.

Abstract Our objective was to evaluate the effects of different vitamin concentrations on growth performance of wean-to-finish pigs under commercial conditions. A total of 900 barrows and gilts (PIC337×Camborough; initially 5.34±0.13 kg) were used in a 136-d growth trial with 25 pigs per pen and 12 pens per treatment in a randomized complete block design. Experimental diets were fed in 3 phases during nursery (5-6, 6-13, and 13-26 kg) and 5 phases during grow-finish (26-44, 44-65, 65-87, 87-108, and 108-128 kg). Dietary treatments consisted of: 1) NRC: vitamin concentrations following NRC (2012) recommendations; 2) PIC: vitamin concentrations following PIC (2016) recommendations; 3) Low-PIC: vitamin concentrations that ranged from 0 to 91% of PIC recommendations. Data were analyzed using the GLIMMIX procedure of SAS with pen as the experimental unit. During the nursery period, pigs fed PIC and Low-PIC diets had greater (P&lt; 0.05) average daily feed intake (ADFI) compared to pigs fed NRC diets. There was no evidence (P &gt;0.10) for differences in average daily gain (ADG) and feed efficiency (G:F). During the grow-finish period, there was no evidence (P &gt;0.10) for differences in growth performance. During the overall wean-to-finish period, pigs fed PIC diets had lower (P&lt; 0.05) ADG and final body weight compared to pigs fed NRC and Low-PIC diets. There was no evidence (P &gt;0.10) for differences in ADFI or G:F. Pigs fed PIC diets had the greatest serum vitamin D3 at the end of nursery and finish periods (P&lt; 0.05) and the greatest serum Vitamin E at the end of nursery period (P&lt; 0.05). In summary, pigs fed PIC and Low-PIC diets had greater nursery feed intake and serum vitamin E and D3 concentrations compared to pigs fed NRC diets. Data from this study have demonstrated that pigs fed diets with reduced vitamin concentrations compared to PIC (2016) recommendations had improved wean-to-finish growth rate.

The objective of this study was to evaluate the effects of the addition of two levels of calcium propionate on lamb performance and some carcass characteristics. Twenty-one male Creole lambs with an initial weight of 25.3 ± 3.3 kg were randomly assigned to one of the following treatments: 0, 10, and 20 g of calcium propionate/kg of diet (dry matter basis). Intake, daily gain, feed conversion, carcass weight, and rib eye area were not affected (P < 0.05) by calcium propionate addition. Ruminal fermentation was not altered (rumen pH, volatile fatty acids concentration, and fermentation pattern), and ruminal ammonia-N presented a quadratic response (P < 0.05). In fat from the longissimus dorsi muscle, oleic acid showed a linear decrease (P < 0.05) and α-linolenic presented a linear increment (P < 0.05). The addition of 10 or 20 g of calcium propionate in diets containing 350 g/kg grain and 100 g/kg molasses did not modify the productive performance of lambs or ruminal fermentation, and minor changes were detected in long-chain fatty acid in intramuscular fat.

In order to evaluate the ethnoveterinary effect of Macleaya cordata extract on bacteria colony forming units (CFU) in different organs of gastrointestinal tract and productive parameters of broilers challenged with Salmonella typhimurium, eighty one day old Cobb broilers were randomly assigned either to a diet without additive or with additive at 50 g/ton during 21 days. The count of CFU of Salmonella typhimurium in crop, gizzard, and duodenum, at 21 days, showed broilers that received the Macleaya cordata extract had a reduction. The broilers also had higher final body weight, total gain, average daily gain and better feed conversion value as compared with those that had not received it. Feed intake was not affected. Results concluded that Macleaya cordata extract is an ethnoveterinary alternative efficient for control of Salmonella typhimurium and a growth promoter in broilers.

Abstract The objective of this study was to evaluate the performance and meat characteristics of castrated and intact Santa Inês male lambs slaughtered at three different thicknesses of subcutaneous fat. Thirty-four lambs, approximately 3 months of age, 19.37 ± 3.73 kg of body weight were used. Four weeks prior to the experiment, half of the animals were castrated. Lambs were further divided into three groups, according to the criteria for slaughter: fat thicknesses of 1, 3 and 6 mm; measured with an ultrasound equipment. All animals received the same diet. Criteria of 1 and 3 mm were achieved after 39 and 84 days in feedlot. As the criterion of 6 mm was not attained up to 130 days of confinement, lambs were slaughtered at that time, with 4 mm of fat thickness. Fat thickness measured with a caliper on the carcasses were 0.87, 3.11 and 3.60 mm. There were no interactions (P > 0.05) between sexual conditions and slaughter criteria. Average daily gain was similar (P > 0.05). Among criteria (average of 0.267 ± 0.052 kg/day). However, final body weight (29.94 ± 2.03; 40.42 ± 2.67 and 53.85 ± 2.03 kg) and feed conversion (4.17 ± 0.39; 4.71 ± 0.43 and 6.01 ± 0.39) were different (P0.05) among criteria, panelists found that lambs slaughtered with 3.6 mm of fat thickness were less (P < 0.05) desirable. Average daily gain (0.283 ± 0.013 vs 0.247 ± 0.012 kg) was greater (P < 0.05) for intact than castrated lambs; however, the meat of intact lambs was less desirable. The other traits were similar for both sexual conditions. We can conclude by the performance and meat results that it is better to slaughter Santa Inês lambs with 3 mm of fat cover, and for the best acceptability of the meat the lambs should be castrated.

Background: Due to the resistance that various pathogens have developed to the unplanned use of antibiotic growth promoters (AGPs) and the risk to consumers health that this implies, AGPs could be replaced by natural products such as plants, essential oils or extracts. The current study was aimed to investigate the effects of a feed additive based on papaveraceae roots and nanoclays (Sangromix 10x®) on broiler performance. Methods: One hundred and twenty Cobb broilers one d old, were randomly assigned to a diet without additive or with additive at 20 g/t during 49 d. Broilers had free access to concentrate and fresh water and were weighed daily. Feed intake and body weight was measured daily and where used to estimate average daily gain and feed conversion ratio. Result: Broilers that received Sangromix 10x®, had higher final body weight, total gain, average daily gain and better feed conversion value as compared with broilers with no additive. The additive did not affect feed intake. The inclusion of Sangromix 10x® increased final body weight and improved feed conversion value and it can be concluded that is an efficient alternative for broiler production. Nevertheless, further research is required to determine their effect on meat and carcass quality, internal organs and blood biochemistry.

Abstract The present study evaluated the effect of dietary inclusion levels of infertile eggs powder (IEP) from the hatchery processing industry on the performance of kampong chickens measured at 6 weeks. A total of 120 birds at 21 d (327±18 gram) were equally distributed to receive 10%, 20%, and 30% of IEP with control treatment without IEP. Each treatment group was replicated five times with eight birds in each, giving three dietary treatments including control. Diets were formulated to meet the Indonesia National Standard of the nutrient requirement for kampong chickens. Results showed that increasing dietary IEP at 10% and 20% significantly increased average daily gain (ADG), final body weight (BW), and decreased feed conversion when compared to control (p<0.05). When given at 30%, no effect on production performance parameters was observed. In conclusion, the present study suggests that infertile eggs powder can be partially used to substitute conventional protein sources in kampong chickens. Dietary inclusion of IEP up to 20% given in mixed with corn in the formula improves the performance of kampong chickens without negatively affecting feed intake.

Maize,which suppliesmost of the energy in poultry feeds, has low yields inNigeria and there is competition for the limited harvest of maize between industrial, livestock and human needs. Thus, this study was carried out to evaluate the effects on the growth and carcass characteristics of broiler chickens of replacing the high inputs grain,maize,with a low inputs grain, 'acha', or medium inputs grains, sorghum and millet. Four isocaloric and isonitrogenous diets for both the starter and finisher phases were formulated with maize, sorghum, millet and 'acha' as the main source of energy and were used as treatments 1, 2, 3 and 4, respectively.Marshall broiler birds were brooded up to 2 weeks before the treatments were introduced that lasted six weeks.Up to 8 weeks of age, body weight, average daily gain, feed conversion ratio and mortality were recorded weekly. The results of the study show no significant differences (P>0.05) between the four treatments in final body weight and average daily gain but birds on treatment 4 ('acha') had significantly lower feed intake and superior feed conversion ratio than the other experimental diets. Itwas concluded thatmaize can be replaced with sorghum, millet and 'acha' without adverse effects on the performance of broiler chickens.
