Digestive Processes

The aim of researches is to develop physiological bases of sheep productivity through improved adaptive capacity of the organism. In comparative aspect the peculiarities of the digestive processes in sheep of different genotypes: the domestic sheep and their hybrids with argali. The experiments were carried out in L. K. Ernst Institute of Animal Husbandry in tree groups of sheep of different origins (n=3) with a rumen fistula. Animals of group I – sheep-valukh the Romanov breed II – the hybrids of the second generation ewes of the Romanov breed with argali (25% of kinship) and III – hybrids of the third generation of Edilbaj breed (50% of kinship), of the Romanov breed (37.5% of kinship) and argali (12.5% of kinship). Higher feed intake was observed in hybrid animals. So, consumption of dry matter in the second group it was higher by 14.6%, the third with 15.4%, compared to the control, obviously, was determined breed differences in the intensity of the digestive processes. Set that the origin of the animals affects the orientation of enzymatic processes. In the proventriculus hybrid animals it was more intense compared with the number purebred. This is evidenced by a statistically significant increase in hybrid animals of the concentration of volatile fatty acids (12-21.6% to nursing and 8.7-12% after nursing), a significant increase of amylolytic activity of the rumen fluid (1.5-2.04 E/ml), some reduction in the ammonia concentration. Had higher content of total quantity of microbial mass in the hybrids of the Romanov sheep and argali compared to purebred sheep-valukh (227.1-258.0 mg/100 ml). Of further interest is the comparative study of digestive and metabolic processes at hybrid animals for the op for determining the optimal type and structure of diets.

SUMMARYA grazing experiment, conducted for 22 weeks in 1992/93 at Aorangi Research Station, AgResearch Grasslands, Manawatu, New Zealand, compared the productivity of weaned lambs grazing Lotus corniculatus (birdsfoot trefoil) and lucerne (Medicago sativa). Effects of condensed tannins (CT) in lotus were evaluated by studying the responses of lambs to twice daily oral supplementation with polyethylene glycol (PEG). A rotational grazing system with restricted feed allowance was used. Measurements were made of pre- and post-grazing herbage mass, the composition of the feed on offer and diet selected, voluntary feed intake (VFI), liveweight gain (LWG), carcass growth, wool growth and the concentration of metabolites in rumen fluid. For both lotus and lucerne swards, the diet selected was mainly leaf. Lotus contained 34 g total CT/kg dry matter in the diet selected, whilst there were essentially no CT in lucerne. Compared to lambs grazing lucerne, lambs grazing lotus had slightly lower VFI, and higher LWG, carcass weight gain, carcass dressing-out percentage and wool growth. PEG supplementation had no effect on these measurements or upon the composition of rumen fluid in lambs grazing lucerne. However, in lambs grazing lotus, PEG supplementation reduced wool growth (10·9 ν. 12·1 g/day), slightly reduced LWG (188 ν. 203 g/day), increased rumen ammonia concentration, and increased the molar proportions of /.so-butyric, isovaleric and n-valeric acids and protozoa numbers in rumen fluid. PEG supplementation did not affect carcass gain, carcass fatness or the molar proportion of rumen acetic, propionic or n-butyric acids in lambs grazing lotus. It was concluded that the principal effect of CT in growing lambs grazing lotus was to increase wool growth without affecting VFI, thereby increasing the efficiency of wool production, that the greater rate of carcass gain of lambs grazing lotus than those grazing lucerne was mainly caused by factors other than CT and that CT did not affect the rumen fermentation of carbohydrate to major volatile fatty acids.

Medicinal herbs have been used for several thousand years in traditional medicine and are known to be inexpensive, effective, readily available, and safe to use, with almost no side effects. As no previous research focused on the effect of ginger powder (Zingiber officinale) on acid-base balance in sheep, the goal of this study was studying the effects of ginger (Zingiber officinale) powder on acid-base balance, rumen, and blood constituents. Ten Egyptian ewes were given ginger powder 500mg/kg bwt orally in the morning before feeding for 5 days. Blood and rumen juice samples were collected in the morning on 0 (control), 3rd, and 5th day before feeding. Results generally showed a significant increase in rumen fluid pH, WBCS, lymphocytes, MCH, and MCHC. Significant decrease in total volatile fatty acids, serum total protein, and globulin were recorded. Ginger maintained acid-base balance, rumen protozoa activity, total protozoa count, rumen ammonia concentration, RBCs, PCV, Hemoglobin, neutrophils, albumin, BUN, Creatinine, GGT, and AST within normal range. Depending on changes in blood and rumen constituents we may suggest a recommendation for using ginger supplementation as 500mg/kg bwt orally for 3-5days as an immune stimulant and in the treatment of rumen acidosis and respiratory affections in sheep.

SUMMARYDiurnal variations in microbial protein nitrogen, total volatile fatty acids and ammonia were examined in two wethers fed once and twice daily with 0·4 kg of concentrateand 0·4 kg hay/day. The total protein nitrogen varied during the day from 76·9 to 130·2 mg/100 ml of rumen fluid. The greatest amount of protein nitrogen was noted immediately before feeding and the smallest 4 h after feeding. The protein nitrogen of rumen protozoa formed about 39·8–53·4% of total protein nitrogen in rumen fluid. Volatile fatty acids varied from 74·0 to 130·5 m-mol/1 of rumen fluid and ammonia from 187·0 to 305·6 mg/1. The higher concentration of total and protozoal protein nitrogen and of VFA was observed when animals were fed twice daily. The changing of feeding frequency from once to twice daily caused an increase of ammonia concentration in the rumen of only one wether. The results obtained are discussed.

The aim of this study was to investigate the prevalence and therapeutic management of indigestion in milch cows in and around Bhubaneswar, Odisha. Crossbred milch cows (n=257) with the history of anorexia presented to Teaching Veterinary Clinical Complex, College of Veterinary Science and Animal Husbandry, OUAT, Bhubaneswar and in private herds in and around Bhubaneswar were examined for indigestion following standard procedures to identify the type of indigestion leading to decrease in milk yield. Clinical examination, determination of pH, study of rumen protozoa, rumen bacteria were carried out in three different types of indigestion. Amongst the affected animals, 48.33 % (n=58), 21.67 % (n=26) and 30.00 % (n=36) were detected to be affected with simple, acid and alkaline indigestion, respectively. Simple indigestion was higher (p < 0.05) as compared to acid and alkaline and alkaline indigestion (30 %) was found to be the next to simple indigestion. Ruminal movement varied from 1-4 per 5 min and pH of the rumen fluid ranged from 7.5-8.6 and the idophillic activity of the rumen protozoa was moderate type (+++). Average total count of protozoa was estimated to be 3.5 - 4.6 x 105 per ml with an average of 4.1 x 105 per ml of rumen liquor and drugs used in the study were found efficacious to treat the different types of indigestion.. Rumen bacteria have played role resulting in production of volatile fatty acids and lactic acid thereby decreasing / disturbing the rumen pH to non-physiological levels, reducing efficiency of rumen microflora.

The accuracy of two different methods in measuring the ammonia nitrogen (N-NH3) concentration in rumen fluid were evaluated: a catalyzed indophenol colorimetric reaction (CICR) and the Kjeldahl distillation (KD). Five buffered standard solutions containing volatile fatty acids, true protein, and known ammonia concentrations (0, 3, 6, 12, and 24 N-NH3 mg/dL) were used to simulate rumen fluid. Different ratios (10:1, 7.5:1, 5:1, 2.5:1, 1:1, 1:2.5, 1:5, 1:7.5, and 1:10) of a potassium hydroxide solution (KOH, 2 mol/L) to standard solutions were evaluated by the KD method. The accuracy of each method was evaluated by adjusting a simple linear regression model of the estimated N-NH3 concentrations on the N-NH3 concentrations in the standard solutions. When the KD method was used, N-NH3 was observed to be released from the deamination of true protein (P<0.05), and an incomplete recovery of N-NH3 was observed (P<0.05), except for 7.5:1 and 5:1 ratios of KOH solution to standard solutions (P>0.05). The estimates of the N-NH3 concentration obtained by the CICR method were found to be accurate (P>0.05). After the accuracy evaluation, ninety-three samples of rumen fluid were evaluated by the CICR and KD methods (using the 5:1 ratio of KOH solution to rumen fluid sample), assuming that the CICR estimates would be accurate. The N-NH3 concentrations obtained by the two methods were observed to be different (P<0.05) but strongly correlated (r = 0.9701). Thus, it was concluded that the estimates obtained by the Kjeldahl distillation using a 5:1 ratio of KOH solution to rumen fluid sample can be adjusted to avoid biases. Furthermore, a model to adjust the N-NH3 concentration is suggested.

AbstractThe objective of this study was to determine the effects on animal performance and rumen digestion characteristics of supplementing cattle grazing autumn grass offered at two levels of allowance, with concentrates formulated from different carbohydrate sources. Seventy-two steers (494 (s.e. 38·4) kg) were assigned to one of six treatments which were arranged in a two grass allowances (5·5 or 11 kg grass dry matter (DM) per head per day) by three concentrate types (starch, starch + fibre or fibre-based diets) factorial design. The experiment commenced on 22 August and had a mean duration of 84 days. Concentrates were formulated to have similar metabolizable energy and crude protein and animals were offered 5 kg per head daily. Grass allowances were offered daily and concentrates were offered individually. Six rumen fistulated steers were used concurrently in a Latin square design to determine the effect of the diets on rumen digestion characteristics. Grass and concentrates degradabilities were measured using the nylon bag technique. The concentrate DM was degraded at 0·189, 0·102 and 0·094 per h for the starch, starch + fibre and fibre-based diets, respectively. Concentrate carbohydrate source and grass allowance did not affect (P> 0·05) degradation rate of grass DM or nitrogen in the rumen, rumen fluid pH, rumen fluid concentration of volatile fatty acids, total lactic acid or ammonia concentration or plasma concentration of glucose, urea or beta-hydroxybutyrate. Animals offered the low grass allowance had larger (P< 0·05) diurnal variation in the rumen fluid acetate: propionate ratio than those offered the high grass allowance. Increasing grass allowance increased (P< 0·01) carcass gain whereas concentrate type had no effect. There was no interaction between concentrate carbohydrate source and grass allowance on any of the production variables measured. It is concluded that the rumen environment in cattle grazing autumn grass buffered the effects of concentrate carbohydrate degradability such that similar productivity was achieved with each concentrate.

In two in vitro experiments with the RUSITEC-apparatus, Brachiaria dictyoneura was tested alone and with legumes at dietary proportions of 1/3, 2/3, or 3/3 of Arachis pintoi (Expt 1) and 1/3 of Arachis pintoi, Cratylia argentea, or Calliandra calothyrsus (Expt 2). In Expt 2, all diets were evaluated with and without 80 mg/g diet of Sapindus saponaria fruits. In Expt 1, the stepwise replacement of the grass by A. pintoi curvi-linearly increased rumen fluid concentrations of ammonia, volatile fatty acids, bacteria, and protozoa. Methane release rates were 1.7, 7.3, 8.8, and 9.0�mmol/day. With increasing legume proportion, more organic matter and protein were degraded, the latter being only partially recovered as ammonia. In Expt 2, 1/3 of A. pintoi basically had the same effects as in Expt 1. Cratylia argentea was less effective in modifying the fermentation pattern. In association with a higher nutrient degradation and rumen ammonia concentration, C. argentea and A. pintoi increased methane release to about 3- and 4-fold levels. Calliandra calothyrsus reduced nutrient degradation and methane release per gram of organic matter degraded. Tannins, predominant in C. calothyrsus, might have affected methanogenesis. Sapindus saponaria reduced methanogenesis by 11% on average in grass-alone and legume-supplemented diets.

Abstract Background and aims: Gestational diabetes represents a form of diabetes diagnosed during pregnancy that is not clearly overt diabetes. In the last trimester of gestation the growth of fetoplacental unit takes place, thus maternal hyperglycemia will determine an increased transplacental passage, hyperinsulinemia and fetal macrosomia. The aim of our study was that o analyzing the effect of maternal glycemia from the last trimester of pregnancy over fetal weight. Material and method: We run an observational study on a group of 46 pregnant women taken into evidence from the first trimester of pregnancy, separated in two groups according to blood glucose determined in the third trimester (before birth): group I normoglycemic and group II with hyperglycemia (>92mg/dl). Results: The mean value of third trimester glycemia for the entire group was of 87.13±22.03. The mean value of the glycemia determined in the third trimester of pregnancy was higher in the second group (109.17 mg/dl) in comparison to the first group (74.,21 mg/dl). The ROC curve for third trimester glycemia as fetal macrosomia appreciation test has an AUC of 0.517. Conclusions: Glycemia determined in the last trimester of pregnancy cannot be used alone as the predictive factor for fetal macrosomia.

The rumen contains abundant microorganisms that aid in the digestion of lignocellulosic feed and are associated with host phenotype traits. Cows with extremely high milk protein and fat percentages (HPF; n = 3) and low milk protein and fat percentages (LPF; n = 3) were selected from 4000 lactating Holstein cows under the same nutritional and management conditions. We found that the total concentration of volatile fatty acids, acetate, butyrate, and propionate in the rumen fluid was significantly higher in the HPF group than in the LPF group. Moreover, we identified 38 most abundant species displaying differential richness between the two groups, in which Prevotella accounted for 68.8% of the species, with the highest abundance in the HPF group. Functional annotation based on the Kyoto Encyclopedia of Gene and Genome (KEGG), evolutionary genealogy of genes: Non-supervised Orthologous Groups (eggNOG), and Carbohydrate-Active enzymes (CAZy) databases showed that the significantly more abundant species in the HPF group are enriched in carbohydrate, amino acid, pyruvate, insulin, and lipid metabolism and transportation. Furthermore, Spearman’s rank correlation analysis revealed that specific microbial taxa (mainly the Prevotella species and Neocallimastix californiae) are positively correlated with total volatile fatty acids (VFA). Collectively, we found that the HPF group was enriched with several Prevotella species related to the total VFA, acetate, and amino acid synthesis. Thereby, these fulfilled the host’s needs for energy, fat, and rumen microbial protein, which can be used for increased biosynthesis of milk fat and milk protein. Our findings provide novel information for elucidation of the regulatory mechanism of the rumen in the formation of milk composition.
