Concrete Mixer

Pasture hay of 18 per cent crude protein content was chaffed and sprayed with an 8 per cent solution of formaldehyde in a concrete mixer. This, or similar untreated chaffed hay was fed to Merino weaner sheep in four experiments as follows: 1. Twenty-four sheep grazing in a 0.9 ha paddock were penned individually three times a week and fed 700 g of either treated or untreated hay. During the intervening periods they were released and allowed to graze. 2. Twelve sheep penned indoors were given 300 g day-l of either treated or untreated hay as a supplement to a basal diet of hay which contained nine per cent crude protein. 3. Twelve sheep penned indoors were fed either treated or untreated hay ad libitum. 4. Six sheep in metabolism cages were fed either treated or untreated hay at a daily rate of 52 g kg-I liveweight0.75 A crossover experimental design was used. Wool production, body growth and, in experiment 4,nitrogen balance were recorded. Attempts were also made to gauge the effectiveness of the treatments in protecting the protein from ruminal degradation. Although the level of protection obtained compared favourably with that obtained by other workers with forages, significant differences in animal production were shown only in experiment 2, where the basal hay was utilized less efficiently for body growth when the supplement was treated, in experiment 3. where treated hay was utilized less efficiently for body growth, and in experiment 4, where wool growth was increased by 10 per cent and nitrogen retention was also increased by treatment of the hay. It was concluded that the magnitude of any likely beneficial response to treatment is too small to warrant this treatment of hay being undertaken on a large scale.

The proximate and mineral constituents of six plantain forms, raw green plantain (RGP), cooked green plantain (CGP), raw ripe plantain (RRP), cooked ripe plantain (CRP), green plantain meal (GPM) and ripe plantain meal (RPM) were determined by chemical analysis. 24 large white barrows, weighing initially, between 40-45 kg., were used to study the apparent digestibility of nutrients, digestible energy (DE), metabolizable energy (ME), metabolizable energy corrected for nitrogen retention (ME(n) and total digestible nutrients when the plantains served as the only source of nutrients. In a second experiment ME and ME(n) were measured for the plantain forms using 28 Large White barrows, with diets in which the plantains replaced 50% of maize in a basal diet. All the plantain forms had low fat, crude fibre and crude protein content but high in nitrogen-free extract, phosphorus, potassium and Iron. Identically high dry matter (D.M.) and nitrogen-free extract (N.F.E.) digestion coefficients were obtained for all the plantain forms except RPM, which had significantly lower values. Digestion coefficients for crude protein (46.9, 53.6, 51.8, 34.3,-32.7 %), crude fibre, (46.6, 49.5, 58.7, 62.6, 56.9, 39.6 %), ether extract (55.9, 56.6, 66.9, 69.2, 54.7 and 34.6 %) for RGP, CGP, RRP, CRP, GPM and RPM respectively were considerably lower than for D.M. and N.F.E. The DE, ME ME(n) and TDN values were comparable for all plantain forms except RPM, which had significantly lower values in most cases. The fresh green plantains and green plantain meals had slightly higher energy values than the ripe plantains, even though the nutrients in the ripe plantains were better digested than in the green forms. The results are discussed in relation to variations in the relative proportions of the simple and more complex carbohydrates during ripening.

ABSTRACTSixty entire male pigs between 7 and 28 days and 60 entire male pigs between 28 and 56 days of age were given ad libitum basal diets using peanut meal and wheat gluten with or without dried milk as the protein supplements. The diets contained between 7·0 and 10·7 g lysine per kg. These diets were supplemented with graded additions of synthetic L-lysine hydrochloride.It was found that the lysine required for maximum performance and nitrogen retention was at least 12·7 g/kg dry matter (DM) between 7 and 28 days of age and not greater than 12 g/kg DM between 28 and 56 days of age. These values are 4·7 and 5·3 g/kg dietary crude protein for the two ages or 0·81 and 0·79 g/MJ digestible energy.A method is discussed for the calculation of the most economical level of lysine supplementation. This is dependent on the cost of the basal diet and lysine, and the value of the weight gain.The concentration of free lysine in the blood plasma did not give a clear indication of lysine requirement of the pigs.

Weaner Pigs

Two experiments were carried out with 108 weaner pigs of the large White and Large X Landrace breeds, to determine the effects of feeding graded levels of Carbadox (Mecadox), a relatively new synthetic feed medicant with bactericidal and growth promotion properties, to weaner pigs on their levels of performance and their nutrient utilization abilities in the hot humid tropical environment. Two management conditions, a clean and an untidy conditions were tried. The basal diet was a 19% crude protein diet to which were added 0.0, 10.0, 25.0 and 50.0ppm levels of Carbadox to give a total of our diets which were fed either individually or in groups to the piglets within each of the four treatment group. Digestibility trial was carried out in the middle of experiment 1 only. In both experiments, pigs on the 50 ppm diet grew at a faster rate than the pigs on the other diets, but significantly faster in experiment 2 only. Feed consumption was slightly stimulated by the presence of Carbadox though not significantly, while the efficiency of feed utilization was significantly improved in experiment 2, being best for the 50 ppm diet and worst for the control Carbadox diet. The difference in the nutrients digestion coefficients and nitrogen retention, all of which were close for all treatments, with no consistent trends

The effect of post ruminal methionine, dietary methionine or dietary sulfur (S) supplementation on nitrogen retention and S excretion was determined by using three Holstein steers fitted with abomasal cannula in a 3 × 3 Latin square design. The basal diet was fed ad libitum and consisted of ground timothy hay and concentrate in a 5:1 ratio. The diet contained 12% crude protein with urea contributing about 40% of the total nitrogen. Elemental S (0.05%) or methionine (0.22%) was added to the diet while a similar quantity of methionine was infused into the abomasum. Abomasal infused methionine compared with supplemental dietary S or methionine resulted in a 16.6 and 23.9% increase in percent of absorbed nitrogen retained, which was not statistically significant (probability approximately 0.25). Sulfur intake and apparent S digestibility was similar for all treatments; however, urinary S concentration tended to be lower for the elemental S treatment (probability approximately 0.10). Sulfur retention was higher (P < 0.05) with supplementary elemental S than when a similar amount of S was consumed or infused in the form of methionine.

The Difference

Pre-pressed, solvent-extracted rapeseed and solvent-extracted soybean meals were fed with a basal diet to Holstein bull calves at levels to support maintenance or growth. Maintenance requirement was based on digestible energy (DE) = 145 W0.75 (kg). Growth rates of 0.55 and 0.75 kg per day were supported by intakes of 1.66 and 1.92 × maintenance for rape-basal and soy-basal diets. The digestibility of proximate components and energy were determined by the "difference" procedure. The derived crude protein digestion coefficients of rapeseed and soybean meals were 89 and 93%, resulting in digestible protein contents of 35 and 47%, respectively. The gross energy digestion coefficient was lower (P < 0.01) at the maintenance level of intake than at the level for growth, for both mixed rations (81, 89 for rapeseed meal and 78, 88 for soybean meal). The mean caloric values of rapeseed and soybean meals derived by difference were 3213 and 2926 kcal DE/kg dry matter, respectively. It was concluded that rapeseed meal is lower in digestible protein content but equal to or greater in DE value than soybean meal.

Feathers are naturally made up of non-digestible proteins. Under thermal processing, total tract digestibility can be partially improved. Furthermore, Bacillus subtilis (Bs) has shown a hydrolytic effect In vitro. Then, a Bs FTC01 was selected to hydrolyze enough feathers to produce a meal, and then test the quality and inclusion in the dog’s diet to measure the apparent total tract digestibility coefficient (ATTDC) in vivo and the microorganism’s ability to survive in the gastrointestinal tract. A basal diet was added with 9.09% hydrolyzed Bs feather meal (HFMBs) or 9.09% thermally hydrolyzed feather meal (HFMT). Nine adult dogs were randomized into two 10-day blocks and fed different diets. Microbial counts were performed on feather meal, diets and feces. The Bs was less effective in digesting the feathers, which reduced the ATTDC of dry matter, crude protein, energy and increased the production of fecal DM, but the fecal score was maintained (p > 0.05). The digestible energy of HFMT and HFMBs was 18,590 J/kg and 9196 J/kg, respectively. Bacillus subtilis showed limitation to digest feather in large scale, but the resistance of Bs to digestion was observed since it grown on feces culture.

Dietary Treatments

Alternative growth promoters are able to not only effectively replace the traditional use of antibiotics but also provide additional health benefits for livestock and reduce food safety concerns. This study investigated the effects of dry Hydrastis canadensis on the laying performance and fecal microbial community of laying hens. Twenty-four Lohmann (LSL, white layer strain) hens were reared from 40 to 48 weeks of age and randomly allotted to four dietary treatments (six birds/treatment). The dietary treatments comprised a basal diet with no treatment as control, a basal diet plus 0.6% powder of dry Hydrastis canadensis roots (R) or leaves (L), and a basal diet plus 0.6% powder of a mixture of dry Hydrastis canadensis roots and leaves (1:1, LR). No mortality was observed in the whole experimental period. The results indicated that albumen height in the LR group was significantly greater than that in the control group. The diet supplemented with Hydrastis canadensis had no significant effects on egg production rate, egg weight, eggshell strength, eggshell thickness, Haugh unit, or yolk height during the whole experimental phase. However, principal coordinate analysis, comparative heat map analysis, and cluster dendrogram analysis of cecal microbiota showed distinct clusters among the groups treated with Hydrastis canadensis and the control group. Regarding blood biochemical parameters, serum cholesterol levels were significantly lower in all Hydrastis canadensis-treated groups compared with those in the control group. Moreover, serum low-density lipoprotein levels were lower in hens supplemented with the leaf of Hydrastis canadensis. The abundances of the phyla Fusobacteria and Kiritimatiellaeota were increased (p < 0.05) in laying hens fed with 0.6% Hydrastis canadensis leaves, whereas the abundance of the phylum Firmicutes in cecum digesta decreased in response to treatment with Hydrastis canadensis roots and leaves. The relative abundance of the Fusobacterium genus was higher in the LR group compared with that in the control. On the contrary, we found a different trend in the Synergistes genus. The potential influences of these microbiota on the performance of laying hens were discussed. The results demonstrate that Hydrastis canadensis can improve the egg albumen height and modulate the cecum digesta microbiota composition of laying hens.

Rate Of Accumulation

Carrots were grown on soils polluted by heavy metal salts. Each particular microelement reached a high concentration [molybdenum (Mo) 39.00, cadmium (Cd) 2.30, lead (Pb) 4.01, mercury (Hg) 30.00, and selenium (Se) 36.20 mg/kg dry matter] in the carrot. In a metabolic balance trial conducted with 15 male and 15 female New Zealand White rabbits, the control animals (n = 5) were fed ad libitum with concentrate as basal diet, while the other rabbits received the basal diet and carrots containing the particular microelement. Blood samples were taken to determine the activity of serum enzymes. To investigate the metabolism of Mo, Cd, Pb, Hg and Se, samples were taken from the heart, liver, lungs, kidneys, spleen, ovaries/testicles, entire digestive tract, adipose tissue, femur, hair, faeces and urine. Carrot had significantly higher digestibility for all nutrients than the rabbit concentrate. Carrot samples of high Pb content had the lowest digestibility of crude protein. The microelements differed in their rate of accumulation in the organs examined: Mo and Cd accumulated in the kidneys, Pb in the kidneys, liver, bones and lungs, Hg in the kidneys and liver, while Se in the liver, kidneys and heart. The proportions of microelements eliminated from the body either via the faeces and urine (Mo 80.18% and Se 47.41%) or via the faeces (Cd 37.86%, Pb 66.39%, Hg 64.65%) were determined. Pathohistological examination revealed that the rate of spermatogenesis was reduced in the Mo, Cd, Pb and Hg groups compared to the control. Lead, Cd and Hg intake resulted in a considerable decrease in gamma-glutamyltransferase (GGT) and in an increase of alkaline phosphatase (ALP) activity because of damages to the kidneys and bones. All experimental treatments decreased the activity of cholinesterase (CHE) because of lesions in the liver.

SUMMARYThe digestibility, the voluntary intake and the nitrogen balance of 108 diets corresponding to 94 silages prepared from 20 fresh crops were measured in growing sheep. Series of silages were made from the same fresh forage. Each series included two controls: a direct-cut silage without additive and a direct-cut silage with formic acid, with a variable number of experimental silages with different additives.Rumen ammonia concentration, measured on rumen-fistulated sheep, decreased when an additive was used. It increased with nitrogen intake and was inversely related to the organic-matter digestibility and the crude-fibre digestibility. It varied with the silage composition.The crude-protein digestibility of direct-cut silages without additives was similar to or slightly higher than the crude-protein digestibility of the fresh crops. The addition of formic acid depressed the digestibility, but the addition of formaldehyde decreased it even more. The urinary nitrogen loss was higher for silages without additive than for the fresh crops and was decreased by the addition of formic acid. The addition of formaldehyde to formic acid had an additive effect.Retained nitrogen was lower in silages without additives (12% of nitrogen intake) than in parent crops (15·7%). It increased when formic acid (15·8%) was added. The addition of formaldehyde at a low rate (1·5 l/t green fodder) to the formic acid did not increase the nitrogen retention whether expressed in g/day or as percentage of nitrogen intake, but the addition of formaldehyde at a high rate (3·5 l/t green fodder) to formic acid decreased nitrogen retention. The other additives based on cereals or whey did not improve the nitrogen balance compared with formic acid. Nitrogen retention differed according to plant species.Retained nitrogen increased with digestible organic-matter intake and nitrogen intake. It increased with the silage water-soluble carbohydrate content. The higher the silage fermentation product content (ammonia, lactic acid, propionic acid), the lower the retained nitrogen. It appears that the nitrogen value of silages can be high provided that the silages are well preserved and that excessive protein breakdown is avoided.

Feeding trials involving a total of 78 Holstein steers and utilizing barley diets were conducted to determine the effects of vitamin E and trace minerals, hay, diethylstilbestrol, and physical form of the barley on rate of gain, feed efficiency and carcass characteristics.In the first trial, a basal diet containing 13.2% crude protein was used. Inclusion of a vitamin E, manganese, zinc, copper and sulfur supplement, 10% hay, or urea in the pelleted diets, or implantation with 9 mg of diethylstilbestrol at the initial weight of 92 kg did not improve rate of gain or dressing percent (P < 0.05). The inclusion of 10% hay reduced feed efficiency (P < 0.05).In the second trial in which dry-rolled, steam-rolled, dry-rolled and pelleted, and steam-rolled and pelleted barley diets were fed, the dry-rolled diet gave slower gains than the diets containing steam-rolled barley or steam-rolled, pelleted barley (P < 0.05). Implanting steers fed the steam-rolled, pelleted diet with 24 mg of diethylstilbestrol at 240 kg liveweight increased rate of gain over other treatments (P < 0.05). Treatments did not affect feed efficiency. Dressing percent was increased in steers fed steam-rolled barley in comparison with those fed dry-rolled barley.
