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.

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.

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.

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.

This experiment was carried out to evaluate the animal performance, feed efficiency and carcass characteristics of 27 crossbred bulls (½ Angus vs. ½ Nellore), finished in feedlot for 120 days, with the addition of distinct levels of essential oils in the diets. The experiment was conducted in a completely randomized trial and animals were distributed into three treatments: control (CON), addition of 500 mg/kg of DM/animal/day of a mix of essential oils (E500), and addition of 1000 mg/kg of DM/animal/day of a mix of essential oils (E1000). The essential oils supplemented to the diets were based on a combination of vegetal extracts from: oregano, garlic, lemon, rosemary, thymus, eucalyptus and sweet orange. The bulls had an average age of 12±2 months and weight of 243.4±6.8 kg when the trial started. The roughage and concentrate ratio was 10% and 90%, respectively. The inclusion of essentials oils in the diets did not affect final body weight, average daily gain, and feed intake, but there was a tendency for improved feed efficiency for the E500 treatment. The ADG ranged from 1.55 to 1.70. Average DMI and feed conversion were 7.07 kg/day and 4.31, respectively. Essentials oil levels did not affect the carcass characteristics. More studies are needed to elucidate the synergism of combinations of essential oils in the rumen.

Noi chicken is one of the most popular native breeds in the South of Vietnam because their good meat quality and disease resistance. Therefore, although price of their products (eggs and meat) is always high, they are always preferred. However, there have not been many studies on the morphology of this breed yet. In the current study, a total of 355 Noi chickens (164 males and 191 females) at 28 days old were selected and randomly allotted to individual cages until they reached the market weight at 84 days old. During the experiment, Noi broilers were fed ad libitum a diet with 17% crude protein and 3.000 kcal/kg ME produced by GreenFeed Vietnam Joint Stock Company. Average daily gain, feed conversion ratio and some morphological dimensions were recorded at two different stages of age (28-56 and 56-84 days old). Results were demonstrated that (i) significant differences in feed intake (P=0.006), body weight (P=0.019), beak length (P=0.014), thigh length (P=0.004), shank length (P=0.003), breast diameter (P=0.000), and thigh diameter (P=0.001) were found between males and females as well as between different stages; and (ii) body weight and some dimensions will increase rapidly at the first stage. An understanding on these economic traits helps researchers and producers have a more detailed glance on developing of each part of Noi chicken at different stages of age which they are the basic scientific foundation for further studies on this breed.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.
