Abstract Probiotics are being considered as an alternative means to reduce pathogen infection and improve animal health especially around the time of weaning. The objective of our study was to evaluate the effects of the use of a probiotic in diets for piglets on their performance and intestinal integrity during nursery phase. Thirty-six piglets (18 barrows and 18 females), weaned at 24 days of age were distributed in a randomized block design, with six repetitions per treatment (with or without addition of 50g/ton of the probiotic Bacillus subtilis DSM 32315, GutCare®, Evonik Industries) and each repetition with three pigs per experimental unit. During the experimental period, performance parameters evaluated were body weight (BW), daily feed intake (ADFI), feed conversion, average daily weight gain (ADG) and the intestinal integrity assessed via galactose absorption capacity. The performance data were submitted to the PDIFF option of the SAS and compared using the Tukey test. During phase 1 (24 to 31 days of age) the use of the probiotic tended (P = 0.07) to improve ADG (+76 g/ d) in comparison to control. As for phase 2 (32 to 39 days of age), 3 (40 to 53 days of age) and 4 (54 to 70 days of age) the use of the probiotic increased the ADFI (+118, +66 and +162 g/ d, respectively; P < 0.05) and ADG (+5 and +8%, respectively for phase 2 and 3; P < 0.05) compared to control. The use of the probiotic improved (P = 0.05) nursery end BW (+1.3 kg) and overall ADFI (+8%; P = 0.046). The intestinal integrity was not affected by treatments (P > 0.10) at any stage. In conclusion, the use of the probiotic Bacillus subtilis DSM 32315 in diets for weaned piglets can be used as a viable formulation strategy to improve performance and the intestinal health of the animals during nursery phase.

Blood Creatinine

Ninety barrow piglets weaned at 21 days old were used to evaluate the effects of guanidinoacetic acid (GAA) supplementation on their performance and blood creatinine and creatine kinase (CK) levels during the nursery phase (21 to 63 days old). The piglets were distributed in a randomized block design with five treatments (0, 0.05, 0.10, 0.15, and 0.20% GAA inclusion), six repetitions, and three animals per repetition. The experimental rations were formulated to meet the nutritional requirements for the phases of 21 to 32, 33 to 42 and 43 to 63 days of age. The experimental diets and water were offered ad libitum throughout the experimental period. At 42 and 63 days old, blood was collected from one animal in each experimental unit for creatinine and creatine kinase analysis. The analysed variables were daily weight gain (DFG), daily feed intake (DFI), and feed conversion (FC) in the 21 to 42 days old and 21 to 63 days old of the nursery phase. All variables were subjected to analysis of variance and regression analysis. We adopted ? = 0.05, and considered a trend to be present when ? was between 0.05 and 0.10. In the pre-initial period (21 to 42 days old), there was an increasing trend in daily weight (P = 0.069), which increased to the level of 0.97% of GAA inclusion. The DFI and FC were not significantly affected by the addition of different GAA levels in the diet. Creatinine levels in the blood at 42 and 63 days old were not significantly influenced by the treatments. The level of CK at 42 days old showed an increasing trend (P = 0.077) that occurred quadratically to the level of 0.085% of GAA inclusion, with no significant difference for this variable at 63 days old. The use of GAA did not promote improvements in performance or blood creatinine and CK levels in piglets in the nursery phase.

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.

And Behavior

In modern pig farming, the search for systems that promote environmental quality and welfare is an important issue. In this sense, the present study evaluated the effects of environmental enrichment on the performance and behavior of piglets. In a completely randomized block design, 32 piglets (7.43kg mean weight), weaned at 28 days of age, were distributed into four treatments (control without enrichment, environmental enrichment with wood shavings as bedding; environmental enrichment with hanging toys and environmental enrichment with wood shavings + hanging toys). Four repetitions were performed for each treatment, with two animals per experimental unit. The instant scan sampling technique was used to record the behavior of each piglet for 20h. Animals receiving environmental enrichment with wood shavings + hanging toys were heavier at 70 days (P=0.02), exhibited higher total and daily weight gain (P=0.04 and P=0.02, respectively) and better feed conversion (P=0.02). Environmental enrichment increased the interaction of animals with the environment, allowing them to exhibit natural behaviors.

ABSTRACT: The present study was performed to evaluate the association of chromium-yeast and selenium-yeast as nutritional additives to enhance performance and quantitative characteristics in the carcass of finishing barrows. A total of 48 barrows, commercial hybrid, with initial weight of 68.3±3.5 kg and final weight of 99.6±3.6 kg, were utilized for the study. The animals were distributed in a randomized complete block design, consisting of three levels of chromium-yeast and selenium-yeast (i.e., without supplementation of chromium-yeast and selenium-yeast, supplementation of 0.4 mg kg-1 chromium-yeast and 0.3 mg kg-1 selenium-yeast, and supplementation of 0.8 mg kg-1 chromium-yeast and 0.6 mg kg-1 selenium-yeast) with eight replicates and two animals per experimental unit. The supplementation of chromium and selenium-yeast did not significantly affect (P>0.05) the average daily feed intake, digestible lysine, crude protein and metabolizable energy intake, average daily weight gain, feed conversion, weight and carcass length, back fat thickness, muscle depth, percentage and amount of lean meat, and carcass allowance. These findings suggest that supplementation of chromium and selenium-yeast does not affect the performance or quantitative characteristics in the carcass of finishing barrows.

The aim of this study was to assess the influence of various diet processing methods and physical forms on digestibility and zootechnical performance parameters of nursery piglets. The study was performed in 2 phases. The first phase was performed twice with 120 piglets per experiment, for a total of 240 newly weaned piglets, in a randomized block design with 6 treatments and 5 replicates (30 pens). The following experimental diets were offered from weaning to 21 days after weaning (initial nursery phase) and included the following: mash diet (M); mash diet conditioned at 60ºC (CM); diet pelleted at 60ºC/matrix 2.5 mm (P2.5); diet pelleted at 60ºC/matrix 2.5 mm and crumbled (P2.5C); diet pelleted at 60ºC/matrix 4.75 mm (P4.75); and diet pelleted at 60ºC/matrix 4.75 mm and crumbled (P4.75C). The animals’ daily weight gain (DWG), daily feed intake (DFI) and feed conversion (FC) were assessed. Phase 2 used 24 piglets (33 days old) from Phase 1, which were lodged in individual metabolic cages. The experiment employed a randomized block design with 4 treatments and 6 replicates: mash diet (M); mash diet conditioned at 60ºC (CM); diet pelleted at 60ºC/matrix 2.5 mm (P2.5); and diet pelleted at 60ºC/matrix 4.75 mm (P4.75). Feces were collected to analyze the digestibility of and apparent digestible energy in dry matter, gross energy and ether extract. The processing and physical form of the diets did not affect the DWG and DFI of the 21- to 39-day-old piglets. The 2.5-mm-diameter pellets induced better FC compared to the crumbled and conditioned crumbled diets (P < 0.05), which might be attributed to the better digestibility of the ether extract in the pelleted diets. Pellet size had no effect on the performance parameters.

Standardized Ileal Digestible Lysine

The experiment was conducted to evaluate five nutritional plans based on sequences of standardized ileal digestible lysine: 0.90-0.80-0.70, 1.00-0.90-0.80, 1.10-1.00-0.90, 1.20-1.10-1.00, and 1.30-1.20-1.10% fed to gilts from 60 to 99, 129 to 100, and 130 to 148 days of age, respectively. Eighty commercial hybrid gilts, selected for lean gain, with initial weight of 23.46±0.27kg were allotted in a randomized block design, with five treatments, eight replicates, and two pigs per experimental unit. No effect (P>0.05) of the nutritional plans was verified on daily feed intake, daily weight gain and feed conversion. The nutritional plans had no influence (P>0.05) on any of the carcass traits evaluated (carcass yield, meat amount, and meat yield). The nutritional plan of 0.90-0.80-0.70% standardized ileal digestible lysine fed to gilts from 60 to 99, 100 to 129, and 130 to 148 days of age, respectively, meets the standardized ileal digestible lysine requirements of gilts from 60 to 148 days of age.

Abstract The objective of this study was to compare Activo Liquid supplemented via the water agaisnt Mecadox 50 on nursery pigs’ growth performance and survival. Activo Liquid is a combination of secondary plant compounds plus organic acid (antimicrobial) supplemented in the water to support gut health and improve performance. The study design of this trial was a Split Plot with 36 replicates (9 replicates/treatment) with 10 pigs/pen. Pigs were allotted by a Randomized Complete Block Design by weight at weaning. Pigs were around 5.7 kg and 19 days of age average on body weight and weaning age, respectively. The nursery houses were not washed for two turns to expose the animals to serious pathogens. The data were analyzed by analysis of variance with pen as the experimental unit. Significant differences were established by P < 0.05. Treatments were Control with 50g/ton of Mecadox for all nursery phases and three Activo Liquid treatments (6 oz per 128 gallon of drinking water administered either for 3, 5 or 7 days post-weaning). A typical nursery feeding program was followed: Phase 1 from d 0 to d 7, Phase2 from d 8 to d 21 and Phase 3 from d 22 to d4 2. They contain 23%, 21% and 19% crude protein respectively. The results showed no significant difference on final body weight among the treatments. All Activo treatments had improved (P < 0.05) feed conversion (Feed:Gain) when compared with the medicated treatment. Activo Liquid 5d treatment post-weaning had numerically lower mortality when compared with all the other treatments. In conclusion, the results of this trial showed that the supplementation of Activo Liquid for 5 d post-weaning at 6 oz/128 gallon of water can safely replace Mecadox 50 g/ton. More research is needed to validate the repeatability of these results and understand Activo Liquid’s mode of action as a powerful antimicrobial.

Two experiments were conducted to evaluate the performance, the energy and nutrient balance and economic viability of production of growing pigs fed diets with reduced levels and phytase. In experiment 1, 60 barrows and gilts (initial weight 25 ± 1.72 kg) were housed in a randomized block design with three diets, ten replicates and two animals per experimental unit (one male and one female). One of the diets was formulated with a reduced level with phytase and evaluated in comparison to a positive-control diet that was formulated according to the nutritional recommendations for animals of this breed, and a negative-control diet without phytase. The different diets did not affect feed intake, but the diet with phytase promoted better final weight, daily weight gain and feed conversion, although it did not differ from the positive control diet. In experiment 2, 27 barrows (initial weight 49 ± 3.67 kg) were housed in random blocks with three diets and nine replicates with experimental plot represented by one animal. The diets did not affect the balance of energy and nutrients but had a significant effect on the efficiency of utilization of calcium and phosphorus, which was the lowest in animals that received the positive-control diet. Economic viability improved when nutrients were reduced and phytase was added in the ration. The addition of phytase (500 ftu/kg) in rations formulated with nutritional levels reduced for growing swines improves rearing productivity and it is economical viable.

Randomized Block Design

It was used 72 pigs, 36 castrated males and 36 females, with initial weight of 14.97 ± 0.36 kg to evaluate levels of dietary available phosphorus (aP). The animals were distributed in a completely randomized block design, with six levels of aP (0.107; 0.214; 0.321; 0.428; 0.535 and 0.642%), six replicates and two animals (one castrated male and one female) per experimental unit. Air temperature and relative humidity in the room were kept at 24.5 ± 1.2°C and 76.3 ± 8.5%, respectively. The levels of aP influenced both daily feed intake and daily weight gain, which increased in a quadratic way up to the estimated levels of 0.420% and 0.443%, respectively and feed conversion, which improved in a quadratic manner up to the estimated level of 0.461%. It was observed the effects of levels of aP on quantity of phosphorus and ash in the bone, which increased in a quadratic manner up to the estimated levels of 0.525% and 0.520%, respectively. Levels of Ap affected daily protein deposition in the carcass, which increased in a quadratic way up to the estimated level of 0.394%. There was no effect of levels of aP on daily fat carcass deposition. Levels of aP that provided the best results for daily weight gain, feed conversion and bone mineralization in swines with high genetic potential for lean meat kept in thermoneutral environment, from 15 to 30 kg are 0.443, 0.461 and 0.525%, respectively, corresponding to estimated daily intakes of 5.25, 5.45 and 6.14 g of aP.

This study was carried out to evaluate the effects of increasing levels of digestible methionine+cystine on performance and carcass composition of high genetic potential barrows for lean deposition. Sixty-four barrows with initial weight of 95.46 ± 1.09 kg were allotted to a completely randomized block design, with four levels of digestible methionine+cystine (0.427, 0.466, 0.504, and 0.545%, corresponding to the digestible methionine+cystine:digestible lysine ratios of 57.0, 62.0, 67.0 and 73.0%, respectively), with eight replicates, and two animals per experimental unit. Experimental diets and water were provided ad libitum until the end of the experimental period when pigs reached 125.21 ± 2.49 kg. Levels of digestible methionine+cystine did not affect daily intake, daily weight gain and feed conversion of the animals, but they affected daily intake of digestible methionine+cystine which increased linearly. Levels of digestible methionine+cystine did not affect carcass weight, meat amount, backfat thickness at P2, and daily meat deposition. The digestible methionine+cystine level of 0.427%, corresponding to the digestible methionine+cystine:lysine ratio of 57.0% and to a daily digestible methionine+cystine intake of 14.20 g/d, provides the best performance and carcass traits for high genetic potential barrows in the phase of 95 to 125 kg.
