Fifty-two litters involving 380 pigs from Duroc (D), Landrace (L) and D × L breed groups were used in one experiment and 12 rats in another to assess the nutritive value of broken rice and corn as energy sources in starting diets of pigs from 3 to 10 wk of age and in diets of rats from 21 to 49 days of age. Dietary treatments in the pig experiment consisted of either broken rice, corn, or a broken rice/corn mixture (1:1) as the major ingredients or a control diet based on corn and soybean meal with 20% dried skim milk. Similar diets based on broken rice, corn or the mixture were used in the rat experiment. No significant differences were found during the pre-weaning period, but postweaning body weight at 8 and 10 wk of age, feed consumption and rate of gain were significantly (P < 0.05) greater for pigs fed the control diet. Rate of gain was significantly (P < 0.05) less and feed:gain ratios were significantly (P < 0.05) greater for broken rice than other diets in the pig experiment. Digestibility of energy was greater for broken rice than for other diets but digestibility of nitrogen was low for all diets. Lower feed intake and daily gain of pigs from Duroc and crossbred gilt breed groups was noted compared with pigs from Landrace or crossbred sow groups. No significant differences between dietary treatments were noted in the rat experiment. Digestible energy was estimated for all diets at 3,300–3,400 kcal/kg for pigs and 3,500–3,550 kcal/kg for rats.

Twenty-four 6-wk-old pigs were housed in individual metabolism cages and exposed for 6 wk to either 2 C or 20 C with ad libitum feed and water. The pigs at 20 C and 2 C had an average daily gain (ADG) of 544 g and 343 g (P < 0.01), respectively. Feed consumption was similar for both treatments, with feed:gain ratios being significantly lower in the 20 C group during the 1st and 3rd 2-wk periods. Spleen and kidney weights were a larger percent of ingesta-free body weight in pigs housed at 2 C. The percent body weight of livers, thyroids, testicles, seminal vesicles and bulbo-urethral glands were not statistically different between 20 C and 2 C housed pigs. Body protein and ash were 5 and 1.3% lower in the 2 C pigs. Differences in plasma ACTH between treatments within day were significant. Consistently lower levels of plasma ACTH were obtained from pigs housed at 2 C.

Feeding trials were conducted to determine the significance of the reduction in feed consumption observed when growing pigs were fed complete diets containing approximately 6 ppm vomitoxin. Sixty Landrace weaners, weighing on average 22 kg, were randomly assigned to four dietary treatments. The dietary treatments were: (1) control cereal soybean diet fed ad libitum (mycotoxin free); (2) vomitoxin diet fed ad libitum in which 100% of the clean wheat included in the control diet was replaced by moldy wheat containing 10.32 ppm vomitoxin; (3) control diet fed restricted to the average daily intake of pigs fed the vomitoxin diet; and (4) upgraded vomitoxin diet fed ad libitum and containing approximately 20% more energy, crude protein, minerals and vitamins. Individual feed consumption was recorded daily for 12 wk. The control diet promoted significantly (P < 0.05) greater total body weight gains and also the greatest feed consumption. Body weight gains were not different (P > 0.05) for the vomitoxin and restricted control dietary treatments. The vomitoxin upgraded treatment resulted in greater total body weight gains (P < 0.05) than the vomitoxin treatment. During the 12-wk period, animals in the vomitoxin and restricted-control-fed groups consumed 71% as much feed as the control group fed ad libitum while the vomitoxin upgraded group consumed 77% as much as the control. Analysis for blood urea nitrogen, creatinine, plasma protein and alkaline phosphatase revealed no differences (P > 0.05) between dietary treatments. With respect to animal performance and blood biochemical profiles, the effect of vomitoxin appears to be primarily limited to feed acceptability and intake, with no apparent consequences on the metabolic function of the animal.

An experiment was conducted for a period of 56 days with 36 healthy New Zealand White (NZW) rabbits aged about one months having weight from 370 to 390g to evaluate the effects of dietary citric acid on growth performance, feed consumption and digestibility of nutrients as well as immune status. The experiment was designed with 6 dietary treatments having 6 rabbits per treatment. Rabbits of control treatment (T1) were given the diet without citric acid (CA) but the dietary treatments T2, T3, T4, T5 and T6 contained 0.5, 1.0, 1.5, 2.0 and 2.5% CA respectively. Green grass was supplied on ad libitum basis. The total body weight gain was Addition of CA at the level of 2% enhanced body weight significantly (P<0.05). (P<0.05)(P<0.05) T 734, 776, 812, 862, 911 and 740g for the rabbits fed 0, 0.5, 1.0, 1.5, 2.0 and 2.5% CA containing diets respectively. Total DM intake also increased with increasing the percentage of CA up to 2% level . Incase of feed conversion ratio, there was no significant difference in addition to different levels of CA. Supplementation of CA improved dry matter, crude protein and ether extract digestibility but incase of crude fiber and nitrogen free extract, there was no significant difference. Non significant difference was also found incase of acidity of feed and feces. The highest lymphocyte (73%) was counted in dietary treatment T6 having 2.5% CA, which was 17% higher than the control diet. From the result of this experiment, it may be concluded that the addition of CA up to 2% level in diet improves performance, digestibility of nutrients and immune status of growing rabbit.

Feeding trials were conducted to evaluate the effect of including vomitoxin-contaminated wheat (VCW) containing 6.9 mg vomitoxin per kilogram in the complete diet of gilts during gestation and lactation (3 wk) and in the initial diet of weanling pigs up to approximately 23 kg liveweight. Four groups of four littermate gilts were assigned to four dietary treatments (one littermate per treatment) as follows: (1) control with 69% clean wheat (CW) in the diet with 16% crude protein; (2) 1/3 replacement of the CW with VCW; (3) 2/3 replacement of the CW with VCW; and (4) 100% replacement of the CW with the VCW. During gestation gilts were fed 2.3 kg/day of the diet in two meals, and the same diet ad libitum during lactation. The level of vomitoxin (VT) did not have any detrimental effect on body weight change of the gilt during gestation and after farrowing. Ad libitum feed consumption of the gilts during lactation was not significantly different among treatments. Litter size and weight at birth and at weaning time was not affected by the level of VT intake during gestation. One hundred and four weanling piglets (56 males and 48 females) weighing approximately 7.0 kg each were included in an 8-wk feeding trial. Four dietary treatments, including the control diet (treatment 1), contained 73.2% CW and 22% crude protein, and treatments 2, 3 and 4 in which VCW replaced 1/3, 2/3 and 100% CW, respectively. A significant (P < 0.05) reduction in body weight gain in the 8-wk period was observed only when 100% of the cereal included in the diet was VCW. This effect was due to a significant reduction in feed consumption of the piglets. Thus, feed efficiency was not affected by the level of VT content of the diet.

Abstract Two trials were conducted to assess the acceptance, safety and digestibility of diets containing various inclusion levels of partially defatted black soldier fly (Hermetia illucens) larvae (BSFL) meal and BSFL oil by dogs. In Trial 1, five extruded diets were evaluated for acceptance in adult Beagle dogs (n=20; 10 male, 10 female) during a 48-hour period. Diets contained graded levels of BSFL meal (5.0, 10.0, and 20.0%), or graded levels of BSFL oil (2.5 and 5.0%), and all diets were well-accepted. Thus, a digestibility trial (Trial 2) was run with 56 adult dogs (16 male, 40 female) allocated into seven dietary treatments; dogs were offered an extruded control diet containing no BSFL meal or oil, or extruded diets where BSFL meal partially replaced poultry by-product meal and corn meal at dietary levels of 5, 10, or 20% inclusion, or diets with BSFL oil partially replacing poultry fat at a 1:1 ratio at levels of 1, 2.5, or 5% inclusion. The treatment diets were fed for 28 days, during which time dogs were monitored for health (via physical examinations, clinical observations, and blood chemistry and hematology) and ingredient evaluation (via body weight, feed consumption, stool observation, and fecal nutrient apparent total tract digestibility). There were no significant differences in body weight or food consumption between treatment groups (P &gt; 0.05) and daily observations indicated that the general health of the animals was maintained throughout the study. Stool quality was maintained at 3.2 to 3.4 (on a five-point scale with a score of one being watery diarrhea and a score of five being hard, dry and crumbly) per treatment group over the fecal observation period (days 22-27), indicating a well-formed, sticky stool. All group mean hematology and blood chemistry parameters remained within normal limits for dogs. Apparent total tract digestibility of dry matter, protein, fat, and calories was not affected by treatment (P &gt; 0.05). In general, amino acid digestibility was not impacted by treatment although some minor changes were observed. Apparent total tract digestibility was high for all nutrients examined. Overall, it was concluded that BSFL meal and BSFL oil are well-tolerated by dogs and their consumption results in no impact to physiology that would be concerning. Based on these data, BSFL meal and oil did not affect general health and could be included safely in dog diets.

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

Abstract A total of 109 sows (Line 241; DNA, Columbus, NE) were used in a study to evaluate the effect of increasing phytase concentration in lactation diets on sow and litter performance. On d 107 of gestation, sows were blocked by body weight and parity and allotted to 1 of 3 dietary treatments of increasing phytase concentration (0, 1,000, or 3,000 FYT/kg; Ronozyme HiPhos 2700; DSM Nutritional Products, Inc., Parsippany, NJ). The control diet contained no phytase and was formulated to contain 0.50% standardized total tract digestible phosphorus (STTD P; 0.45% available P) and 0.62% STTD calcium (0.90% total Ca). The same STTD P and Ca concentrations were formulated for the phytase diets considering a release of 0.132 STTD P and 0.094 STTD Ca in both diets. Diets were fed from d 107 of gestation until weaning (d 18 ± 2). Litters were cross-fostered within treatment until 48 h post-farrowing to equalize litter size. Linear and quadratic response to phytase concentration was evaluated using the lmer function in R. There was no evidence for difference in sow body weight change, farrowing performance, wean-to-estrus interval, or litter size among dietary treatments. Sow average daily feed intake from farrowing to weaning tended to increase (linear, P=0.093) as phytase increased. Although not significant (linear, P =0.226), farrowing duration decreased as phytase increased. Litter weaning weight increased (quadratic, P=0.039) and overall litter gain increased (quadratic, P=0.047) with 1,000 FYT of phytase. In summary, sow feed intake tended to increase linearly with increasing phytase; however, feeding 1,000 FYT/kg maximized overall litter gain and weaning weight. This small-scale study suggests sow and litter performance benefits due to high inclusions of dietary phytase; however, a commercial trial with more sows is warranted to confirm these results.

The aim of this research was the visual characterization and investigating the effects of Alternaria spp. contaminated wheat grains in the starter stage of broilers nutrition on productive parameters and oxidative stress. The research was divided into two phases. Bunches of wheat in post-harvest period of year 2020 was collected from a various locality in Serbia and Albania. In the first phase, collected samples were visual characterized by Alternaria spp. presence by color measurement methods. Gained results are conferred in the range of the color properties of grain color properties of Alternaria toxins. Wheat grain samples were significantly different (p < 0.05) in terms of all measured color parameters (L*, a*, b*). Classification of field fungi in analyzed wheat grain samples showed that the significant field fungi were Rhizopus spp., followed by Alternaria spp., and Fusarium spp. In the second phase, biological tests with chickens were carried out during the broiler chickens’ dietary starter period in the first 14th days of age. At the beginning of the experiment, a total of 180-day-old Ross 308 strain broilers were equally distributed into three dietary treatments, with four replicates each. Dietary treatments in the experiments were as follows: basal diet without visual contamination of Alternaria spp. with 25% wheat (A1), a basal diet with visual contamination of Alternaria spp. with 25% wheat from Serbia (A2), basal diet with visual contamination of Alternaria spp. with 25% wheat from Albania (A3). The trial with chickens lasted for 14 days. After the first experimental week, wheat infected with Alternaria spp. in treatment A2 and A3 expressed adverse effects. The highest body weight of chickens of 140.40 g was recorded in broilers on control treatment A1 with statistically significant differences (p < 0.05) compared to treatments A2 (137.32 g) and A3 (135.35 g). At the end of the second week of test period, a statistically significant (p < 0.05) difference in body weight of broiler chickens could be noticed. The highest body weight of 352.68 g was recorded in control treatment A1, with statistically significant differences compared to other Alternaria spp. treatments. The lowest body weight of chickens was recorded in treatment A3 (335.93 g). Results of feed consumption and feed conversion ratio showed some numerical differences between treatments but without any statistically significant differences (p > 0.05). Alternaria spp. contaminated diet increased glutathione (GSH), glutathione reductase (GR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) and decreased peroxidase (POD) and superoxide dismutase (SOD) serum levels, respectively. Built on the achieved results, it can be concluded that the wheat contaminated with Alternaria spp. in broilers nutrition negatively affected growth, decreased oxidative protection and interrupted chicken welfare in the first period of life.

Abstract An experiment was conducted to test the hypothesis that addition of Val, Ile, or Trp alone or in combination will reduce the negative effects of excess Leu in diets for growing pigs. A total of 288 growing pigs (28.6 ± 2.5 kg) were randomly assigned to 1 of 9 dietary treatments in a randomized complete block design. There were 2 barrows and 2 gilts in each pen and 8 replicate pens per treatment. A control diet based on corn and soybean meal and 8 diets based on corn and a high-protein corn product (48% crude protein) with 2 levels of crystalline L-Val (0 or 0.10%), L-Ile (0 or 0.10%), and L-Trp (0 or 0.05%) were formulated. The crystalline L-Val, L-Ile, and L-Trp increased standardized ileal digestible (SID) Val:Lys from 70 to 80%, SID Ile:Lys from 53 to 63%, and SID Trp:Lys from 18 to 23%, respectively. All diets were formulated to contain 1.00% SID Lys and the 8 diets containing corn protein contained 171% SID Leu:Lys. Individual pig weights were recorded at the beginning and at the conclusion of the 28-d experiment. Data were analyzed using the PROC MIXED of SAS with a pen as the experimental unit. Diet was the fixed effect and block and replicate within block were random effects. Results indicated that final body weight and average daily gain were not different between pigs fed the control diet and pigs fed the diet with Val and Trp addition, but greater (P &lt; 0.001) than for pigs fed the diet with Val addition, Ile addition, Trp addition, Val and Ile addition, Ile and Trp addition, or Val, Ile, and Trp addition (Table 1). In conclusion, addition of Val and Trp to diets with excess Leu may prevent negative effects of excess Leu in diets for growing pigs.

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.
