Feeding Diets

Purified diets containing 25% lactose, agar, wood cellulose or raw potato starch, or 10% arabinose were compared with a control diet containing cornstarch as the only carbohydrate for effects upon dry weights of cleaned gastrointestinal organs in rats. Many effects of diets upon absolute organ weights and upon organ weights relative to body weight were found. When the lactose diet was fed for 1 week from weaning, the relative small intestine weight and the absolute and relative weights of both the cecum and the colon plus rectum were increased over the controls. When all of the diets were fed for 4–5 weeks, organ weights were increased by diets as follows: relative stomach weight by agar and cellulose, absolute and relative small intestine weights by lactose, relative small intestine weight by arabinose, absolute and relative cecum weights by all experimental diets except cellulose, and absolute and relative colon plus rectum weights by all five experimental diets. Thus, stomach growth is affected by diet little or not at all, while intestine growth is differently affected in its different regions by various diets. Increases in dry weights or numbers of fecal pellets were not at all related to increases in small intestine or cecum weight, and were not well related to increases in colon plus rectum weight. Using these facts and knowledge of certain properties of the various substances, certain ideas as to modes of action of diets in producing the observed changes were excluded.

Optimal intestinal development in gilts is a prerequisite for a better farrowing and a higher feed intake in lactation, and these are important facets in improving animal welfare for sows in a high-performance situation. The present study aimed to evaluate the effects of a fiber-rich diet on these topics. Studies with 20 male Topigs castrates and a performance study with 38 female siblings were conducted. Pigs in both of the groups were offered either a control diet (CG) or a high fiber diet (FG) during the second half of the rearing phase (~97 kg BW) until 7 days a.p. At the time of the insemination of the gilts (body weight >170 kg), the castrates were slaughtered and the morphological parameters of the gastrointestinal tract were taken. In the performance study, the feed intake as well as the number and weight of the live and stillborn piglets and the weaning weight of the litters were recorded. The results indicated that the high fiber diet with a greater swelling capacity was beneficial to the development of the gastrointestinal tract (stomach weight CG = 714 g, FG = 812 g, p = 0.007), increased the litter weight (CG =15.9 kg, FG = 20.6 kg, p = 0.045) and resulted in a higher feed intake during lactation overall (CG = 196 kg, FG = 211 kg, p = 0.035).

Compared to feeding basal (67%) cornstarch or 25% glucose or 25% sucrose diets, feeding a 15% cellobiose diet to rats for 4–5 weeks resulted in diarrhea, smaller body weight gains, greater small gut weight relative to body weight, greater absolute and relative weights of the cecum and of the colon plus rectum, and several differences in stomach weight. In a separate 4–4 1/2-week feeding experiment, the absolute and relative weights of the stomach in three dietary groups were in the order: 67% glucose > 67% sucrose > 67% cornstarch. Also 67% sucrose exceeded 67% cornstarch in absolute and relative small gut weights and in small gut weight: length ratio.

Carcass traits and relative organ weights of growing rabbits fed graded levels of processed (ash treated and rumen liquor fermented) kola nut (Cola nitida) pod husks (PKPH) were investigated. One hundred and twenty (120) weaner rabbits of mixed breeds (New-Zealand white × Chinchilla) of equal sexes and average body weight 525.46g were randomly allotted to four (4) dietary treatments at 0 (0.00 % PKPH), 10 (10 % PKPH), 20 (20 % PKPH), and 30 % (30 % PKPH) inclusion levels and designated as diets 1, 2, 3, and 4, respectively. Each treatment group was replicated ten (10) times with three (3) rabbits per replicate and was fed ad-libitum for 56 days. The highest slaughter weight (1813.80 g/r), dressing weight (1068.70 g/r) and dressing percentage (58.54 %) recorded in rabbits fed diet 3 (20% PKPH) were similar to those fed the control diet (0 % PKPH) and diet 2 (10% PKPH) but was significantly (P<0.05) higher than those fed diet 4 (30 % PKPH). The lungs, liver, kidney, heart, and spleen of the rabbits fed dietary treatments were not significantly influenced. It was concluded that processed kolanut pod husk had no deleterious effect on carcass and relative organs weight of weaner rabbits.

AbstractDietary fibre fermentation in humans and monogastric animals is considered to occur in the hindgut, but it may also occur in the lower small intestine. This study aimed to compare ileal and hindgut fermentation in the growing pig fed a human-type diet using a combined in vivo/in vitro methodology. Five pigs (23 (sd 1·6) kg body weight) were fed a human-type diet. On day 15, pigs were euthanised. Digesta from terminal jejunum and terminal ileum were collected as substrates for fermentation. Ileal and caecal digesta were collected for preparing microbial inocula. Terminal jejunal digesta were fermented in vitro with a pooled ileal digesta inoculum for 2 h, whereas terminal ileal digesta were fermented in vitro with a pooled caecal digesta inoculum for 24 h. The ileal organic matter fermentability (28 %) was not different from hindgut fermentation (35 %). However, the organic matter fermented was 66 % greater for ileal fermentation than hindgut fermentation (P = 0·04). Total numbers of bacteria in ileal and caecal digesta did not differ (P = 0·09). Differences (P < 0·05) were observed in the taxonomic composition. For instance, ileal digesta contained 32-fold greater number of the genus Enterococcus, whereas caecal digesta had a 227-fold greater number of the genus Ruminococcus. Acetate synthesis and iso-valerate synthesis were greater (P < 0·05) for ileal fermentation than hindgut fermentation, but propionate, butyrate and valerate synthesis was lower. SCFA were absorbed in the gastrointestinal tract location where they were synthesised. In conclusion, a quantitatively important degree of fermentation occurs in the ileum of the growing pig fed a human-type diet.

A 28-day feeding trial was conducted to evaluate the effect of honey-flavoured diets on performance, nutrient retention, organ weights and economy of production. 0ne hundred and twenty 4-weeks old 'Anak 2000' broiler chicks were randomly allotted to four treatments, replicated three times with 10 birds each in a completely randomized design (CRD). Four diets were formulated such that diet 1(0%) contained no honey and served as the control, while diets 2, 3 and 4 contained 0.5, 1.0 and 1.5% honey-flavour, respectively. The results showed that diet 4 containing 1.5% honey flavour significantly (P < 0.05) improved the final body weight (1977g), weight gain (1327g), daily weight gain (47.29), feed/gain (2.18) and protein efficiency ratio (2.16) than broiler fed other diets including the control. Broilers on the control diet had the least values of body weight gain (1754g), weight gain (1104g), daily weight gain (39.43g), worst feed/gain (2.59) and protein efficiency ratio (1.80). Broilers fed diet 4 had the highest (P<0.05) nutrient retention of protein (83.80 %), ether extract (86.80 %) and crude fibre (70.50%) while broilers on the control diet had the lowest retention values of protein (65.20%), crude fibre (63.30%) and ether extract (73.70%). The dry matter retentions were similar across the treatments with highest numerical values of 82.80% recorded by birds on diet 4 and least value of 78.80% on diet 1(control). The liver, heart, lungs, kidney and caecum weights did not differ significantly (P>0.05) across the treatments but were numerically higher with increased in the honey-flavoured diets. The gizzard and caecum weights were significantly (P<0.05) increased with increase in honey flavoured diets. Cost per kg feed increased as the level of honey-flavoured inclusion in the diets increased 1.5 % with value of ? 58.00/kg compared to the control diet with ? 47.01/kg while the revenue generated showed that birds fed diet 4 (1.5% honey) were the most economical to produce with value of ? 597.15/bird compared with those on the control (₦ 496.80/bird). Addition of honey at 1.5% demonstrated superiority in this study with no adverse effect on bird's performance and organ.

ABSTRACT. Penelitian bertujuan untuk mengkaji perkembangan bakteri usus halus dan performan ayam kampung silangan kampung-leghorn (KL) akibat ditambahkan ekstrak umbi dahlia dalam ransum. Ternak percobaan yang digunakan adalah persilangan ayam kampung silangan KL sebanyak 200 ekor umur 22 hari dengan rata-rata bobot badan 180,46 ± 1,21 g. Bahan perlakuan meliputi umbi dahlia, ethanol 70%, kertas saring halus serta bahan pakan penyusun ransum (jagung giling, bekatul, bungkil kedelai, tepung ikan, CaCO3 dan mineral dan vitamin mix). Rancangan percobaan yang digunakan rancangan acak lengkap dengan 4 perlakuan dan 5 ulangan (masing-masing unit percobaan diisi 10 ekor). Perlakuan yang diterapkan meliputi: P0=Ransum kontrol/RK, P1=RK+0,39% ekstrak umbi dahlia, P2=RK+0,78 ekstrak umbi dahlia, dan P3= RK+1,17 ekstrak umbi dahlia. Parameter yang diukur meliputi populasi bakteri asam laktat, Escherichia coli, pH digesta tiap masing-masing segmen usus halus dan pertambahan bobot badan harian (PBBH). Data dianalisis dengan menggunakan uji sidik ragam dan jika berpengaruh nyata dilakukan uji beda nyata Duncan pada taraf 5%. Hasil penelitian menunjukkan bahwa penambahan ekstrak umbi dahlia berpengaruh nyata terhadap populasi bakteri asam laktat, Escherichia coli, pH digesta tiap masing-masing segmen usus halus dan PBBH. Kesimpulan adalah penambahan ekstrak umbi dahlia sampai taraf 1,17% sebagai sumber inulin di dalam ransum dapat meningkatkan populasi bakteri asam laktat, menurunkan pH dan Escherichia coli pada masing-masing segmen usus halus serta memperlambat laju digesta dan meningkatkan PBBH.  (Population of small intestine bacteria and performance of native chicken-leghorn crossbreed duo to feeding of dahlia tuber extract) ABSTRAK. This study aims to examine the development of small intestine bacteria and the performances of native chicken-leghorn crossbreed due to the addition of dahlia tuber extract in the diet. Experimental animals were 200 unsex native chicken-leghorn crossbreed, 22 days old with an average body weight of 180.46 ± 1.21 g. Treatment materials include dahlia tuber, ethanol 70%, fine filter paper and feed stuff (yellow corn, rice bran, soy bean meal, fish meal, CaCO3, and vitamin-mineral mix). The present experiment was assigned in a completely randomized with 4 treatments and 5 replications (10 birds each). The treatments were: P0=Control Diet/CD, P1=CD+0,39% dahlia tuber extract, P2=CD+0,78% dahlia tuber extract and P3=CD+1,17% dahlia tuber extract. Parameters measured were the number of Lactic Acid Bacteria (LAB), Escherichia coli, intestinal potential hydrogen (pH) (duodenal, jejunal and ileal), rate of passage and daily body weight gain (DBWG). Data were subjected to ANOVA and followed by Duncan Multiple Range Test on 5% level. The results indicated that feeding native chicken-leghorn crossbreed with the diet containing dahlia tuber extract (DTE) significantly (P0.05) increased LAB population and DBWG, decreased E. coli population and intestinal pH, and slow the rate of passage down. In conclusion, feeding of dahlia tubers as a source of inulin in the form of dahlia tuber extract to a level of 1.17% increased the population of lactic acid bacteria, reduced pH and Escherichia coli in each segment of the small intestine and retard the rate of digestion and increased body weight gain.

Selection Of

Three classes of highly inbred 16-week-old mice, of strain A 2 G / Tb , were studied: (i) controls, kept at 21 °C; (ii) ‘new stock’, of the first or second generations reared in a room kept at –3 °C; (iii) ‘old stock’, of the fourteenth generation reared at –3 °C. All were bred at the same time. The new - stock mice were lighter than the controls, their tails were shorter, and they (especially the females) had less fat. They contained more water, and less nitrogen and collagen. The males, but not the females, had less calcium and phosphorus. The heart, stomach and small intestine were heavier than in the controls, and the intestine was longer. Liver and kidneys, too, were heavier, but these differences were large only in the females. The shaved skin was lighter, but the hair, especially in the females, heavier. Gonad weights were lower. The spleen tended to be lighter, but varied greatly. Most of these differences from the controls resemble those seen in adult laboratory rats exposed to cold for a few weeks. The old stock , of both sexes, had almost the same body-weight as the controls, but re­sembled the new stock in tail-length: hence the effect of cold on growth of the tail was inde­pendent of body-weight. The old-stock males had more fat than the controls, while the females were intermediate between the controls and the new stock. The males contained less water than the controls; while in nitrogen, collagen, calcium and phosphorus they did not differ significantly. The tendency to return towards the control state was less marked in the females. In weights of stomach, intestine and liver the old-stock males again resembled the controls; and their kidneys were lighter . They had, however, longer intestines than the controls and, like the new stock, they had heavier hearts. Their skin was lighter but hair, heavier. The spleen was lighter. Except in their kidneys and spleen, the old-stock females resembled the new-stock females, rather than the controls. Since other work has shown that the old-stock females are more efficient mothers than the new-stock, the old-stock mice of both sexes were clearly better adapted to cold than the new. This may have been due to intracellular changes making individual tissues more efficient. The change in the old stock cannot be due to selection of favourable genotypes; it may be due to a cumulative maternal effect.

Abstract We assessed the effect of maternal feed restriction at different stages of gestation on growth and development of organs and small intestine of newborn goats. A total of 14 pregnant dams were randomly divided into one of the follow dietary treatments: Animals fed at 50% of maintenance requirement from 8-84 d of gestation and then fed at 100% maintenance requirement from day 85 of gestation to parturition (R-M, n = 6), and animals fed at 100% of maintenance requirement from 8-84 d of gestation and then fed at 50% maintenance requirement from day 85 of gestation to parturition (M-R, n = 8). At birth, newborns were slaughtered for collection of corporal components. No differences were observed among treatments for birth weight (P = 0.46). The weight of the complex reticulum-rumen-omasum tended to be heavier (P = 0.057) in the M-R group, when expressed per kg of body weight. The small intestine (P = 0.038) and total intestine (P = 0.038) were heavier in the offspring of the M-R group when expressed in kg of body weight. The M-R newborns had greater length of the small intestine (P = 0.043) and total intestine (P = 0.026). Maternal feed restriction did not influence the intestinal villi height (P = 0.406). However, newborn from R-M group had lower villus height:crypt depth ratio (P = 0.016), due to the tendency of the greater of crypt depth in these animals (P = 0.081). No differences among treatments were observed in mRNA expression of the MGAM and GLP-2R in the jejunum of the offspring (P &gt; 0.12). Newborns of the M-R group tended to present greater mRNA abundance of the SLC5A1 (P = 0.091), SLC2A2 (P = 0.091), and OCLN (P = 0.061). In summary, restriction in the first half of gestation may be more detrimental to the performance and health of offspring throughout life due to increased impairment of intestinal development.

Feeding Diets

Three experiments were conducted to determine the effects of feeding diets containing laboratory synthesized deoxynivalenol (DON), or Fusarium (naturally) contaminated wheat containing DON on performance and health of young pigs (32.8–41.1 kg body weight). Diets containing 3.4–19.1 mg DON kg−1 were fed to pigs ad libitum for 14 d (exps. 1 and 2) or 7 wk (exp. 3) after which time each pig was slaughtered and blood, tissue and organ samples taken for analysis. All pigs responded to DON-contaminated diets with an immediate reduction in feed intake and body weight gain followed by some degree of recovery that was dependent on the dietary DON concentration. Negative linear relationships were found between feed intake or body weight gain and dietary DON concentration with pure DON and naturally contaminated wheat diets. Feed intake and weight gain were, respectively, 18 and 23% lower when a diet containing naturally contaminated wheat was fed compared to a diet containing an equivalent concentration of pure DON. Effects of DON on organ weights, relative to body weight, were inconsistent among experiments. The gastric mucosa was thinner and more eroded and had a higher degree of folding in the esophageal region in most groups fed DON-contaminated diets compared to those fed the control diet. Effects of DON on the fundic and cardiac regions of the stomach were inconsistent among treatments and experiments. There was little or no effect of DON on most of the blood parameters measured.

In 3 experiments growing rabbits were divided into 2 groups. In each case half received a basal ration while the other half was given this ration supplemented with a ground fibrous material: 20% hay, 10% straw or 10% paper. All the diets were fed in pelleted form. In all the experiments the rabbits fed on the diets containing the added fibrous materials gained in weight slightly more rapidly and had slightly higher food conversion ratios than did those on the control diet, but the differences in the means were not significant. A study of the small intestine and caecum weights expressed as percentages of body weight and as the weights of 1-cm lengths showed that the added fibrous materials increased these weights except in 1 instance where the results were the same. Significant changes were recorded in the case of hay in both the percentage weight and the weight of 1-cm lengths of caecum and in the straw experiment in the weight of 1-cm lengths of small intestine. There were no significant changes in the results from the paper-fed rabbits.
