The use of phytobiotics in growth stimulation of weaned pigs

Phytogene feed additives (phytobiotics) are plant origin compounds used in animal nutrition in order to improve their productivity by improving the production performance of animals, feed properties and the quality of food of animal origin. These additives stimulate animal growth by using their natural and physiological potentials and mechanisms providing conditions for the realization of the genetically projected production volumes. Data on the use of phytobiotics as growth stimulators are incomplete and often very contradictory, especially those related to their impact on the health and performance of weaned pigs. Given the relevance and importance of these issues the feeding trial was organized by the group-control system. The experiment lasted for 40 days and it was divided into two phases of 20 days each. Trial was conducted on 24 piglets, F1 generation of Swedish Landrace and Pietrain, weaned from sows at the age of 35 days. Tests were carried out on piglets, with an average body weight of 8.61?1.59 kg, which were subjected to one of the two feeding treatments immediately after weaning. The control group was fed with a mixture without growth promoters, while the experimental group received a diet containing preparation of phytobiotic (Enviva EO 101, Danisco Animal Nutrition) in the amount recommended by the manufacturer (0.1 kg/t). The mixtures for piglets nutrition were formulated in accordance with the recommendations of the NRC (1998), and AEC (1993) and they met the nutritional requirements completely. During the experiment, there was no disturbance of health and/or the manifestation of clinical signs of disease. The control group, fed with the diet without added growth stimulators, achieved body weight (25.32?6.31 kg), average daily gain (0.42?0.12 kg), consumption (0.89 kg) and feed conversion (2.119 ) normal for a given race, age and housing conditions. The use of preparation of phytobiotics as growth promoters, led to better production results in regard to the control group, which was based on higher body weight (27.19?4.77 kg), higher average daily gain (0.46?0.09 kg) and better feed conversion (2.043). The use of phytobiotic, as an alternative option in growth stimulation of weaned pigs, has its nutritive, medical and economic justification.

This study was conducted to evaluate the effects of a toy on the behaviour and body weight of weaned pigs after mixing. Two groups (192 pigs in total, control: without toy; treatment: with toy placed on the floor) of weaned pigs housed in pens (1.8 m × 1.4 m, 4 pigs/pen) were This study was conducted to evaluate the effects of a toy on the behaviour and body weight of weaned pigs after mixing. Two were observed with the aid of video technology for nine consecutive hours in the early (days 1 and 2) and late (days 38 and 39) period after mixing. Bodyweight of pigs at the end of the study (Mann-Whitney U-test, Z = –2.46, P = 0.01) and the average daily gain (Z = –2.75, P < 0.01) were 10% higher in the treatment group than in the control group. The presence of the toy in the pen influenced the pig behaviours. In pens enriched with toys, there was an increase in feeding behaviour and a decrease in agonistic and belly nosing behaviours. Toy supply reduced negative social behaviours and thereby improved the bodyweight of weaned pigs. The results of this study suggest that toys used as environmental enrichment are useful for enhancing pig welfare and effective for farmers.

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.

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.

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.

The effect of feeding barley-wheat-soya finisher, gestation and lactation diets containing (A) 1979 National Research Council (NRC) recommended calcium-phosphorus (Ca-P) levels or (B) 150% of NRC levels from 65 kg body weight (Bwt) on growth and reproduction was studied in two experiments using Lacombe (L) and Yorkshire (Y) gilts. The number of gilts used were 299 (148 L + 151 Y) and 107 (53 Y + 54 Y) in exp. 1 and 216 (106 L + 110 Y) and 101 (49 L + 52 Y) in exp. 2 during finishing and gestation-lactation periods, respectively. The reproductive performance during second parity was measured only in exp. 2 using 85 (36 L + 49 Y) primiparous sows. All pigs were housed in confinement except during breeding and gestation, when they were housed in outside dirt-lot pens. Average daily gain, feed intake, and feed conversion were similar for gilts fed finisher diets A or B in both experiments. In exp. 1, both L and Y gilts fed gestation diet B had more (P < 0.05) total (9.5 ± 0.3 vs. 8.6 ± 0.3) and live pigs (9.2 ± 0.3 vs. 8.2 ± 0.3) born and weaned (7.7 ± 0.3 vs 6.9 ± 0.2) with lower piglet weight gains at 3 wk (3.5 ± 0.1 vs. 3.9 ± 0.1 kg) and 5 wk (6.9 ± 0.2 vs. 7.5 ± 0.2 kg) when compared to gestation diet A group. These differences were not significant in exp. 2. Higher dietary Ca-P levels elevated the serum P during both gestation (7.3 ± 0.1 vs. 7.0 ± 0.1 mg/dL) and lactation (6.2 ± 0.1 vs. 5.9 ± 0.1 mg/dL) periods in exp. 1 but not in exp. 2. The changes in body weight during gestation and lactation, piglet birth weights, and weaning to estrus interval were similar for both treatment groups. These results indicated that the 1979 NRC recommended dietary Ca-P levels may be adequate to support the maximum growth and reproduction in gilts during finishing and lactation but are too low for gestation.

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.

The effect of Bisolbi drug based on Bacillus subtilis on the physiological, biochemical and productive parameters of calves was studied. The research and production experiment was carried out in a dairy farm “Kupinskoe” of Samara Region on 30 calves of the Holstein-Frisian breed. The drug increases the intensity of the anabolic processes in animals: the amount of total protein in blood serum of calves of the experimental group at 120 days of age was higher by 8.9% (p≤0.05), albumin 9.2% (p≤0.01), compared with control animals. The purpose of Bisolbi contributed to the increase in the intensity of carbohydrate-lipid metabolism: cholesterol was higher by 23% (p≤0.01), glucose 0.4 mmol/l (p≤0.05) in blood 120-day calves of the experimental group, relative to the data of the control group. It was found that the body weight of calves in the control group at 100 days of age was 105.23±2.11 kg, in the experimental group -108.6±2.19 kg. The average daily gain in the experimental group was significantly higher by 0.075 kg (p≤0.01). At 120 days of age, the body weight of the experimental calves was higher by 4.19 kg (p≤0.05), the average daily increase by 0.080 kg (p≤0.05), relative to the control animals.
