Growth Trial

The nutritive value of five lots of rapeseed meal (RSM) from Brassica campestris or B. napus with different levels of glucosinolates (GL) was investigated in a digestibility and balance trial with a 5 x 5 Latin square design and in a growth trial with 140 growing-finishing pigs. The RSM’s were prepared from the cultivars: Span-Torch, Sigga, Gulliver and Topas, and a heat-treated RSM was also studied, their total GL contents (µmol/g defatted meal) being 42, 11, 98, 27 and 8, respectively. Cv. Sigga had yellow hulls and a lower ADF content than the other cultivars. The hat-treated RSM had a reduced lysine content. There were no significant (P > 0.05) differences in organic matter or crude protein digestibilities between the RSM’s with different GL levels or the RSM’s prepared from B. campestris and B. napus, when RSM was used as the only protein supplement at a level of 20—25 % in a barley-based diet. Heat treatment reduced the organic matter and crude protein digestibilities (P < 0.01). Nitrogen retention and protein utilization were lower (P < 0.01) on the diet supplemented with heat-treated RSM than on the diets with the other RSM’s but otherwise there were no significant differences between them (P > 0.05). In the growth trial supplementation with HGL-RSM Gulliver (14 % in diet) caused some palatability problems and this led to reduced performance (P < 0.05), but there were no differences between the other groups receiving 14—15 % RSM and the SBM control group (P > 0.05). The carcass quality was similar in all the groups. The weight of the thyroid gland was higher in the pigs receiving RSM than in the SBM controls, by 6—57 % (P < 0.05). In the present study a fairly high RSM supplements from cultivars with a moderate high GL content could be used in the diet of growing pigs without impairing their performance, when the diet was formulated on the basis of the digestible nutrients of RSM. Heat-treated RSM, with protein of low rumen degradability, is of poor value in pig feeding due to the low digestibility and availability of its protein.

Nutritive Values

This study was conducted to determine the nutritive values of shelled, unshelled oak nuts and their shells. For the estimation of dry matter (DM), organic matter (OM) and crude protein (CP), degradability characteristics, digestibilities, energy values and tannin contents of these feedstuffs the nylon bag technique, cellulose feed system and enzyme methods were used. In spite of the fact that in situ dry matter, organic matter and crude protein degradabilities of shelled and unshelled oak nuts were high, the degradabilities of shells were found lower. Degradability characteristics (a, b, a + b) and effective degradabilities were high in unshelled and shelled oak nuts and low in shells. The differences between the oak nut shells and the other two groups were significant for DM and OM degradabilities (P &lt; 0.01). Pepsin digestible N contents were lower in shelled and unshelled oak nuts and high in shells. Unshelled and shelled oak nuts were significantly different from the oak nut shells for digestibility of DM and OM. Energy values were highest in unshelled oak nuts and lowest in shells. Oak nuts can be used as a forage source in regions with their high natural production. &nbsp;

Six diets were prepared using Bonanza barley (B, 1.78% N), Neepawa spring wheat (SW, 2.50% N) or Norstar winter wheat (WW, 2.11% N) with canola meal (CM, 5.70% N) or soybean meal (SBM, 7.62% N) as the protein supplement. Four of the diets (B-15%SBM, B-22%CM, SW-5%CM and WW-15%CM) were formulated to contain 16% crude protein (CP, N × 6.25), while the other diets (SW-15%CM, 18% CP; WW-5%CM, 14% CP) were included to facilitate comparison of both CM inclusion rates in diets based on each wheat. One pen, containing two females and two male castrates, was assigned to receive each diet, ad libitum, from two initial weights (averaging 22.6 and 31.7 kg) to market weight (91 kg). Among pigs receiving the 16% CP diets, growth rates favored the barley-fed groups (802 g∙pig−1∙day−1) and were lowest for those fed the SW-5% CM diet (732 g∙pig−1∙day−1, P < 0.05). Feed:gain ratios ranged from 3.48:1 (B-22%CM) to 3.93:1 (SW-5%CM). Carcass measurements revealed a corresponding pattern with barley-fed pigs producing the leaner carcasses. Results from pigs fed the four wheat-based diets suggested that cultivar effects were minor when the same level of protein supplement was used. Apparent digestibilities of energy ranged from 76% for B diets to 89% for SW and WW diets while coefficients of N digestibility were 68% (B diets), 85% (WW diets) and 88% (SW diets). A palatability study, based on relative consumption of paired diets, revealed a preference for Neepawa over Norstar and for the lower CM levels. Key words: Barley, canola, growing pigs, wheat

Methods Of Evaluation

Commercial samples of solvent-extracted rapeseed meal (RM), 44% crude protein soybean meal (SM) and 50% crude protein SM were evaluated for digestible energy (DE), metabolizable energy (ME), nitrogen-corrected ME (MEn) and digestible nitrogen (DN), using two methods of evaluation. A comparison of results from feeding the test meals for two different lengths of time prior to conducting the determinations was also made. Sixteen castrate male pigs were allotted to each of the two evaluation methods, with four pigs assigned to each of three treatment groups, and four pigs assigned to the basal control group for each method. The two SM samples had higher DE, ME, MEn and DN than the RM sample. The DE, ME and MEn values in kcal/g dry matter for RM were 3.37, 3.13 and 2.76, and for SM they we’re 4.42, 4.21 and 3.71, respectively. The overall mean coefficient for DN was 79.2% for RM and 92.8% for SM. There were no significant differences observed between methods or between the two time periods. The values for the basal diets were uniform throughout the trial, as indicated by low standard errors.

Digestible Crude Protein

Most dry dog foods are based on cereals, but very little published information and few comparative studies are available on the nutritive value of various cereals in dogs. To determine the apparent nutrient digestibilities and feed values of five different autoclave-processed and ground cereals: oat groats, barley, wheat, corn and rice, a digestibility trial was carried out on twelve adult huskies according to a 6 x 4 cyclic changeover design. Total tract organic matter (OM), crude carbohydrate and gross energy (GE) digestibilities were higher in rice than in all the other cereals. Apparent crude protein (CP) and acid hydrolyzed fat digestibilities of rice (80% and 94%, respectively) were as good as for oat groats (81% and 93%). However, oat groats had higher OM, CP and GE digestibilities than barley, wheat and corn. The amount of digestible crude protein (118 g kg-1 DM) was higher in oat groats than in the other cereals. Digestible energy contents (MJ kg-1 DM) of oat groats, rice, corn, wheat and barley were 17.1, 16.0, 15.7, 15.6 and 15.5, respectively. The quantity of excreted wet faeces increased and the percentage of dry matter (DM) in faeces decreased when oat groats, barley, wheat or corn were supplemented to the basal diet, in contrast to rice, which had the opposite effect on wet faeces excretion. Oat groats are good substitutes for rice or other cereals in dry dog foods.;

The digestibility and nutritive value of two rapeseed meals (Brassica campestris) , one prepared from the medium-glucosinolate varieties Span and Torch, and the other from a low-glucosinolate variety Candle, were determined for three pigs weighing about 45 kg. The pigs received 1600 g barley and 600 g rapeseed meal daily. The composition of the Candle meal was better than that of Span-Torch and its digestibility and nutritive value higher (P < 0.01). When the fat content of Candle meal was corrected to the 1.5 % level of Span-Torch meal, the ME values were 13.6 and 10.4 MJ/kg DM, the NE values 1.01 and 0.78 FU/kg DM (FU = 0.7 kg starch), and the DCP values 318 and 248 g DCP/kg DM for Candle and Span-Torch, respectively (P < 0.01). The difference in the nitrogen balance was also significant (P < 0.01). Thus the Candle meal has about 30 % higher nutritive value for pigs than the Span-Torch meal.

Digestibility and nutritive value for growing pigs, liveweight 40-70 kg, were determined for high glucosinolate (HG) Span and Torch (Brassica campestris) rapeseed meals (RSM) and cakes (RSC), and for low glucosinolate (LG)Regent (B. napus) RSM and DF-15 (B. campestris) RSC in barley based diets in one year or two successive years. Some of the feeds were evaluated also for sheep. The level of RSM and RSC was 20 or 30 % of diets for pigs and 32 % for sheep. The observed net energy value of commercial Span-Torch RSM for pigs was in two successive years 0.80 and 0,79 f.u./kg dry matter (DM) ( f.u. = feed unit = 0.7kg starch equivalent).The protein values were 281 and 291 g digestible crude protein (DCP)/kg DM, respectively. The 8 %-units higher fat content together with a little better digestibility of organic components raised the f.u. value of RSC about 30 % above that of RSM. For pigs there were only slight differences in the digestibility and palatability of the HG Span-Torch and the LG Regent and DF-15 meals and cakes, but there was a clear difference in the palatability in successive years. The nitrogen balances for pigs on the RSM or RSC and barley diets were 20.4-22.2 g N/d, and the biological values of protein of the RSM and RSC were 67-68. The net energy value of Span-Torch rapeseed meal for sheep was 0.91 f.u./kg DM, and the protein value 309 g DCP/kg DM. The digestibility of cakes was nearly equal to meal, but the 8 %-units higher fat content raised the f.u. value of RSC about 20 %. The digestibility of organic matter of LG DF-15 cakes was a little better (P < 0.05) than that of Span-Torch cakes. The sheep willingly ate RSM and RSC at a 32 % level of the diets.

Two experiments of a factorial design (sex × treatment) were conducted to determine the effects of enzyme and salinomycin supplementation on the nutritive value of barley or rye-based diets for growing pigs fed from approximately 20 to 85 kg. For exp. 1, 72 crossbred pigs were fed either a barley-based control diet or a similar diet supplemented with enzyme (Aspergillus niger; 750 units g−1 beta-glucanase and 650 units g−1 pentosanase), salinomycin (25 ppm) or both additives in combination. For exp. 2, two replicates of 48 pigs were fed either a barley-based diet, an unsupplemented rye-based diet or a rye-based diet supplemented with enzyme, salinomycin or both additives. During both experiments, chromic oxide (0.5%) was added to the diet of four to six pigs/treatment to act as a digestibility indicator starting when the pigs reached 42 kg. Neither enzyme nor salinomycin, alone or in combination, significantly improved the growth rate or feed efficiency of pigs fed barley or rye. Supplementation of barley with the combination of additives significantly (P < 0.05) improved protein digestibility while neither enzyme nor salinomycin had any effect on nutrient digestibility when fed alone. In rye-based diets, salinomycin, both alone and in combination, significantly (P < 0.05) improved the digestibility of crude protein and energy. Dry matter digestibility of the rye-based diets was unaffected by treatment. Key words: Swine, rye, barley, beta-glucanase, pentosanase, salinomycin

По результатам научных исследований, выполненных за ряд лет в растениеводстве и животноводстве, показана целесообразность интродукции в кормопроизводство Пермского края новой многолетней бобовой культуры эспарцета песчаного. По четырёхлетним наблюдениям (2012 2015 годы) в полевых опытах культура не уступала по урожайности кормовой массы традиционному для региона клеверу луговому, а по концентрации обменной энергии и сырого протеина в сухом веществе была на уровне клевера лугового и люцерны изменчивой, но в разы превосходила их по содержанию сахара. Сенаж это единственный вид зимнего корма, максимально сохраняющий обменную энергию, протеин, сахар, каротин, достаточно концентрированный, чтобы обеспечивать потребности высокопродуктивных животных. В 2018 году на Лобановском молочном комплексе ООО Русь в Пермском районе Пермского края были проведены научнохозяйственный и физиологический опыты по скармливанию сенажа из эспарцета песчаного голштинизированным коровам чёрнопёстрой породы. При использовании сенажа из эспарцета песчаного животные в сутки потребляли сухого вещества на 2,3 3,9 кг на голову больше по сравнению с группой, где в рационе было сено (контроль). В результате использования сенажа из эспарцета песчаного переваримость сухого вещества рациона у опытных групп животных была выше на 2,55 5,80 по сравнению с контрольной органического вещества на 2,54 4,14 . За учётный период научнохозяйственного опыта (120 дней) от коров опытных групп получено по 399327,2 и 414431,9 кг молока, что со средней степенью достоверности выше продуктивности животных контрольной группы (391045,4). По содержанию молочного жира и молочного белка преимущество достоверно также было за опытными группами. Затраты корма на 1 кг молока составили в контроле 0,74 энергетических корм. ед. (ЭКЕ), в опытных группах 0,71 и 0,69 ЭКЕ. Hungarian sainfoin was shown to be an effective perennial legume crop in the forage production of the Perm Territory. For 4 years (2012 2015) this crop produced forage mass, exchange energy and crude protein comparable to the ones of red clover and bastard alfalfa but exceeded them significantly in carbohydrate content. Haylage is the only type of winter forage that has sufficient concentrations of exchange energy, protein, carbohydrates and carotene, satisfying needs of highproductive livestock in nutrients. Haylage from Hungarian sainfoin was fed to Holstein BlackandWhite cows in the frame of experiments conducted in 2018. Cows consumed 2.3 3.9 kg more of dry matter (DM) with the haylage, compared to hay (control). Digestibilities of DM and organic matter were 2.55 5.80 and 2.54 4.14 higher than in the control group, respectively. For 120 days the experimental groups produced 3993 27.2 and 4144 31.9 kg of milk versus 3910 45.4 kg of the control one. The former also exceeded the latter in milk fat and protein contents. Fodder costs per 1 kg of milk amounted to 0.74 energy feed units in the control and 0.71 and 0.69 energy feed units in the experimental groups.

In two digestibility and balance trials with growing pigs, whey protein concentrate (WPC) was compared as a protein supplement with casein (CAS) and dried skim milk (DSM), and, 30 % lactose (40 % dried whey, DW) was compared as a sugar supplement with the same amounts of hydrolysed lactose (HYLA) and sucrose (SUC). The effects of these supplements on protein and mineral metabolism of the pigs were investigated, WPC contained 42.2 % crude protein and had a high content of lysine, 8.6 g, and sulphur containing amino acids: cystine 2.8 and methionine 2.2g/16 g N, These exceeded the values for DSM. The hydrolysing degree of the enzymatically treated lactose syrup was 73 %. WPC had high crude protein digestibility, 99.1 % as compared to 95.4 for CAS and 95.0 % for DSM. Dried whey had low crude protein digestibility, 72.5 %. The amino acids in the WPC diet were highly digestible, but low values were obtained for the DW diet. On the WPC diet, nitrogen retention was higher than with the other protein supplements (P > 0.05), urinary urea excretion was low and the biological value very high. On a combination of WPC and HYLA protein utilisation was higher than on dried whole whey. On the diets supplemented with different sugars, none of the blood parameters differed statistically significantly (P > 0.05) and all values lay within the reference range. Water intake was on average 49 % greater on diets with sugar supplements than without. Urinary excretion of reducing sugars averaged 40.2, 8.3 and 6.6 g/d on the HYLA, SUC and DW diets, while on the diets without sugar supplements the values were 0.8—1.2 g/d. The following mean daily mineral retention values were obtained: P 4.0 g, Ca 5,9 g. Mg 0,4 g, Na 1.9g, K 2.9 g, Fe 27 mg, Cu 6.4 mg, Zn 65 mg and Mn 4.0 mg. The surplus Na and K on the DW diet were excreted in the urine and the pigs did not have diarrhoea.

The development of the yield and nutritive value of timothy (Phleum pratense L.) both in the primary growth and in the regrowth were studied at MTT Plant Production Research, a unit of MTT Agrifood Research Finland, in Rovaniemi (66°35´N) in 1999–2001. The dry matter yield and leaf:stem ratio were measured from the crop samples, and the contents of crude protein and organic matter digestibility of both whole plant samples and leaf and stem fractions were analysed. In primary growth, the most rapid increase of dry matter, 220–240 kg ha-1 per day, was measured around the beginning of the heading stage. There was a very strong positive correlation between the proportion of stems and the amount of dry matter in the primary yield. The daily growth rate of the regrowth was less than half of that of the primary growth. The fastest decrease, 1 percentage unit per day, in crude protein content was measured at the pasture stage (4–5-leaf stage). During the entire sampling period, the average daily decline in crude protein content in the primary growth of timothy was 0.65 percentage units. The main cause for the rapid decline in crude protein content was the high proportion of stem matter and its low protein content. In the regrowth, during the last four weeks before the harvest, the average daily decline in crude protein content was 0.28 percentage units.The average decline in organic matter digestibility from early pasture stage to late silage stage was 0.9 percentage units per day. The most remarkable change was noticed at the growth stage of timothy when about the half of stems were heading and it was then that the digestibility decreased by more than one percentage unit per day. The rapid decline in organic matter digestibility was due to the low digestibility of stem matter. The daily change in forage digestibility in the regrowth was very small, on average 0.11%.;
