Four groups of blue fox (Alopex Lagopus) were fed from weaning to pelting with feed of two different protein levels. The metabolizable energy (ME) from protein amounted to 35/30 % in the control group and to 22/18 % in three low-protein groups during the early and late growth period, respectively. One of the low-protein groups received an unsupplemented diet. The second low-protein diet was fortified with methionine, and the third with methionine and lysine to the same level as in the control diet. Hematological values, urea and creatinine were lower in all low-protein groups as compared to the control group. The activities of amino acid metabolizing enzymes ASAT, ALAT and GOT in plasma were lower in the low-protein groups although the relative sizes of the liver and kidneys were greater. The lowered protein content in the feed was sufficient for growth, and only a slight negative effect on fur characteristics was observed. The dietary supplementation of methionine and lysine yielded no improvement in the fur quality or other parameters as compared to the unsupplemented low-protein feed, indicating that there was no deficiency of these amino acids in these low-protein feeds.

ABSTRACT The objective was to evaluate the effects of cranberry on blood and urinary parameters of dogs (experiment I), digestibility of nutrients (experiment II), palatability of diet (experiment III) and the influence of cranberry on E. coli UPEC-MRHA fimbriae in vitro (experiment IV). For experiment I and II, ten dogs were fed with diets containing 0% or 0.4% cranberry for 30 days. Experiment III compared the diets containing 0% and 0.4% cranberry using 16 adult dogs. There were no statistical differences (P>0.05) in the blood parameters evaluated. Dogs consuming cranberry presented lighter color and appearance of urine, compared to the control group (P<0.05). The diet containing cranberry showed higher digestibility of dry matter, organic matter, ether extract, higher metabolizable energy (P<0.05) and reduced fecal sialic acid concentration (P<0.05) compared to the control diet. There was no influence of cranberry on the formation of fimbriae of E. coli UPEC-MRHA. There was a lower intake ratio of the diet containing cranberry (P<0.05). The inclusion of 0.4% cranberry increases the digestibility of nutrients and influences the color and appearance of urine of dogs. However, it reduces diet palatability and does not alter the adhesion of E. coli UPEC-MRHA in vitro.

Pearl millet, which is comparable to maize in terms of its metabolizable energy content is an identified potential replacement for maize in broiler diets. However, as the competition and price of maize continues to spike, the continuous need to completely replace maize in broiler diets is imperative. Therefore, the objectives of this study were to investigate the effects of feeding diets containing pearl millet supplemented with enzyme NatuzymeTM on the carcass characteristics and haematological values of broiler chickens. 150 two weeks-old broilers were randomly divided into 5 groups with 10 birds per pen translating into 10 birds per replicate and fed an isonitrogenous (23%CP) starter diet of control diet (A); 0% (B); 10% (C); 20% (D); 30.01% and (E) 37.41 % pearl millet. Similarly, an isonitrogenous (21%CP) finisher diet of control diet (A); 0% (B); 10.64% pearl millet (C); 21.28% (D); 31.92% and (E) 39.27 % of pearl millet for 6 weeks. The birds were randomly allotted to the diets in a completely randomized design with feed and water given ad libitum. With the exception of drumstick of birds fed diet D which was significantly lower than the other diets, the results showed that the carcass values (parameters) of broilers fed 100% pearl millet were similar or non-superior to the control group and the other diets. Similarly, blood parameters were not significantly different between groups. These results show that pearl millet supplemented with enzyme can replace maize in broiler diets without affecting carcass yields and haematological parameters.

Nitrogen balance and myofibrillar protein breakdown were studied in 16 double-muscled Belgian Blue bulls during a low growth period (0.5 kg d−1) (LGP) of 4 mo (L4), 8 mo (L8), or 14 mo (L14) and the subsequent fattening period (rapid growth period, RGP). The control group (CG) was given a conventional fattening diet; the others received a low-energy, low-protein diet during LGP, and the same diet as the CG during RGP. Measurements were made halfway through the LGP, l mo after the beginning of the fattening period, and 1 mo before slaughter. Nitrogen balance was about half of CG (P < 0.001) during LGP, e.g., 50.8, 21.3, 25.8, and 23.8 g d−1, for CG, L4, L8, and L14, respectively. Between LGP and RGP, N balance increased by about 18 g N d−1 above the control in the compensating groups L4, L8 and L14. This was due to the higher digestibility and the higher metabolizability of the nitrogen in the fattening diet. Lower muscle protein accretion during the LGP resulted from decreased synthesis (P < 0.001) and degradation (P < 0.05) compared with the GC. When changing to RGP different evolution patterns were observed in the three formerly restricted groups, e.g. after a short restriction (L4) both synthesis and degradation rose during the RGP but declined towards the end. After a longer restriction (L8 and L14), synthesis and degradation increased and remained high. The magnitude of these increases was inversely proportional to the length of the restriction period.

AbstractThe optimum pattern and limiting order of some essential amino acids for growing-furring blue foxes were assessed from nitrogen (N) retention responses. Total tract digestibility and N balance trials were carried out on 24 weaned blue fox males in an 8 ✕ 5 cyclic change-over experiment. Eight experimental diets were prepared by removing proportionately about 0·4 of each of the amino acids studied – methionine + cystine, lysine, threonine, tryptophan and histidine – successively from the amino acid control diet. The main source of protein in the amino acid control diet was casein and an amino acid mixture was added to bring the calculated crude protein (CP) content up to the level of 170 g/kg dry matter (DM). Low-protein (CP 95·7 g/kg DM) and high-protein (CP 166·6 g/kg DM) diets, the protein proportion of which was casein protein, served as negative and positive control diets, respectively. The reduction in N retention when one amino acid in turn was deleted from the amino acid control diet was calculated, and a regression analysis was made between N retention and relative amino acid intake. Data on the animals’ intake of each limiting amino acid and those on the amino acid control diet were used. The optimum amino acid pattern, expressed relative to lysine = 100, proved to be: methionine + cystine 77, threonine 64, histidine 55 and tryptophan 22. The first-limiting amino acids were methionine + cystine. Blue fox responses (N retention, weight gain) to deletion of methionine + cystine from the diet were very severe and exceeded those to deletion of any other amino acid. Moreover, removing methionine + cystine from the diet significantly impaired the apparent digestibility of organic matter, reducing it to a level even lower than that of the low-protein diet. After methionine + cystine, the next-limiting amino acid in casein-based diets was threonine, followed by histidine and tryptophan. The results show the importance of verifying the sufficiency of dietary methionine + cystine in the practical feeding of blue foxes.

The objective of our study was to investigate the effects of excess Methionine (Met) on the growth performance, serum homocysteine levels, apoptotic rates, and Bax and Bcl-2 protein levels in geese and to study the role of Bet (betaine) in relieving excess Met-induced hyperhomocysteinemia (HHcy). In this study, 150 healthy male 14-day-old Yangzhou geese of similar body weight were randomly distributed into three groups with five replicates per treatment and 10 geese per replicate: the control group (fed a control diet), the Met toxicity group (fed the control diet +1% Met), and the Bet detoxification group (fed the control diet +1% Met +0.2% Bet). At 28, 49, and 70 d of age, the geese in the Met toxicity group had significantly lower body weights than those in the control group (p < 0.05). The serum homocysteine levels in geese at 70 d of age in the detoxification group were significantly lower than those in the Met toxicity group (p < 0.05). Compared with the control, Met significantly increased cardiomyocyte apoptosis rates, while Bet reduced them. In conclusion, our results suggest that excess methionine reduces body weight induced by myocardial apoptosis, and Bet can be used to effectively lower plasma homocysteine levels.

Salts Of Organic Acids

The present investigation was conducted to appraise the effect of different levels of salts of organic acids on the gut morphology and meat quality of broilers. A total 300 day-old commercial chicks were randomly divided into 5 treatments. Each treatment consists of 6 replicates having 10 birds per replicate. The control diet was formulated to contain approximately the same metabolizable energy (ME), crude protein and limiting amino acids (methionine and lysine) as per the requirements of birds. The first group (T1) was fed on control diet without any feed additives, while, groups (T2, T3, T4 and T5) were fed on basal diets containing sodium butyrate and calcium propionate @ 0.5% and 1.0% respectively. Six birds from each treatment (1 per replication) were randomly selected for slaughter and collection of samples and microbial study at day 42. Performance of birds in terms of body weight and feed conversion ratio was significantly improved in treated groups. Results showed that in gut morphology, pH was reduced significantly (P less than 0.05) in T3 and T5 (6.24 and 6.22, respectively) as compared to the control group (6.64) while significant improvement was observed in villus height and crypt depth in all treatment groups and were highest in T3 (539.50µm,135.67 µm). Lowest Coliform bacteria (log CFU/g.)was recorded in T3 (16.57) which was significantly differ with the T1 (19.17) and Lactobacilli count was significantly increased in all treatments as compared to control.Supplementation of organic acids reduced meat cholesterol level significantly and lowest was in T5(48.03mg/dL) followed by T3 (48.30mg/dL). Similarly SFA decreased while PUFA content was increased significantly on supplementation of salts as compared to control.

Abstract This study investigates the mechanism by which maternal protein restriction induces hepatic autophagy-related gene expression in the offspring of rats. Pregnant Sprague-Dawley rats were fed either a control diet (C, 18% energy from protein) or a low-protein diet (LP, 8.5% energy from protein) during gestation, followed by the control diet during lactation and post-weaning. Liver tissue was collected from the offspring at postnatal day 38 and divided into four groups according to sex and maternal diet (F-C, F-LP, M-C, and M-LP) for further analysis. Autophagy-related mRNA and protein levels were determined by real-time PCR and Western blotting, respectively. In addition, chromatin immunoprecipitation (ChIP) was performed to investigate the interactions between transcription factors and autophagy-related genes. Protein levels of p-eIF2a and ATF4 were increased only in the female offspring born to dams fed the LP diet. Correlatively, the mRNA expression of hepatic autophagy-related genes including Map1lc3b, P62/Sqstm1, Becn1, Atg3, Atg7, and Atg10 was significantly greater in the F-LP group than in the F-C group. Furthermore, ChIP results showed greater ATF4 and C/EBP homology protein (CHOP) binding at the regions of a set of autophagy-related genes in the F-LP group than in the F-C group. Our data demonstrated that a maternal LP diet transcriptionally programmed hepatic autophagy-related gene expression only in female rat offspring. This transcriptional program involved the activation of the eIF2α/ATF4 pathway and intricate regulation by transcription factors ATF4 and CHOP.

Crossbred Pigs

Four experiments were conducted with a total of 144 pigs to study the effects on rate of gain, efficiency of feed utilization, digestibility and retention of nutrients and carcass characteristics of adding 0.10% CuSO4∙5H2O to the diets of crossbred pigs, fed ad libitum or restricted to scale, from weaning to market weight. The diets contained either fishmeal or soybean meal as protein supplements and were formulated to contain 14 or 17% protein. For ad libitum-fed pigs, the addition of copper to the diet improved rate of gain by 6.2% and efficiency of feed utilization by 3.8% up to 50 kg liveweight, with a lesser improvement for restricted pigs. The increased gain and reduced feed per kg gain with copper supplements were more apparent when fishmeal rather than soybean meal and a high rather than a low protein level were fed. Rate of gain and efficiency of feed utilization were increased only slightly by copper supplements when the overall growth period to market weight was considered. In digestibility studies, chromium sesquioxide as an indicator and total fecal collection gave comparable results, but digestibility coefficients were higher when the total collection method was used. Energy digestibility and nitrogen digestibility and retention were not consistently influenced by supplemental copper. Metabolizable energy was not altered by supplemental copper in the diet. The carcasses of ad libitum-fed pigs receiving supplemental copper with high protein were generally lower in backfat, and had larger cross-sectional areas of the loin and higher carcass ROP scores, than those receiving no supplemental copper. However, pigs fed ad libitum copper-supplemented diets containing fishmeal yielded a large proportion of carcasses with soft fat. This softer consistency of fat was less apparent in carcasses of pigs fed soybean meal and did not occur at market weight in pigs fed diets restricted to scale.

The purpose of the research is to study the effect of extractive substances from a complex of herbs (R. Carthamoides, S. Coronate, F. ulmaria )on individual indicators of the metabolism of laboratory mice, pregnant sows and piglets obtained from them. A phytoextract containing ecdysteroids and flavonoids was orally administered to white mice ( three experimental and one control group of 15 mice) in doses of 0.1; 0.2 and 0.3 ml during 14 days that provided an increase in the average daily weight gain by 20.8-48.5% (P <0.05) in comparison with the control. The introduction into the diet of pregnant sows (three experimental groups and one control group of 10 sows) of an additive containing a phytoextract once a day at doses 3, 5 and 10 grams per head within 30 days before farrowing did not cause deviations from the norm of the studied biochemical blood parameters (total protein, albumin, cholesterol, calcium, phosphorus, magnesium, urea, creatinine, ALT, AST). The blood parameters of sows in the experimental groups characterizing the metabolic status of the organism were within the reference limits: total protein 60.7±0.4-62.0±0.3 g/l; albumin 44.2±0.4-52.7±1.8 g/l; cholesterol 2.14±0.04-2.90±0.01 mmol/l; Ca 2.50±0.05-2.62±0.01 mmol/l; P 2.91±0.0-3.16±0.04 mmol/l; Mg 0.92±0.02-1.28±0.01 mmol/l; AST 27.6±2.4-29.3±0.5 units; ALT 23.7±1.1-26.9±1.3 units; urea 4.8±0.2-7.9±0.5 mmol/l; creatinine 101.2±3.5-110.0±2.1 mkmol/l. The number of newborn piglets obtained from sows in the experimental groups exceeded the indicator in the control (127 heads) by 6.2%, of which live by 10.6% (in the control, 113 heads), the number transferred for weaning by 11.2% (in control 107 heads), gross growth by 9.8% (control 887 kg). The rest of the studied parameters of piglets (average weight of a piglet during transfer, average daily growth, survivability) did not differ significantly from the control (P> 0.05). It has been established that the phytoextract had an anabolic effect on white mice, did not cause a negative effect on the studied biochemical parameters of metabolism in pregnant sows, and contributed to an increase in the number of live newborns in comparison with the control.
