Sowing Seed

There have been presented the study results on the effect of pre-sowing seed ozonation of narrowleaf lupin (Lupinus angustifolius) and common oat on their germination energy, germination capacity, productivity and product quality. The study was carried out in the period from 2018 to 2020 in laboratory and field conditions of the Kostroma RIA, the branch of the FSBSI “Russian Potato Research Center named after A.G. Lorkh”. The purpose of the current study was to find out the efficiency of pre-sowing seed treatment with an ozone-air flow and treatment with a biological product for their germination energy, germination capacity, productivity and product quality. The objects of the study were the common oats variety ‘Yakov’ and the narrowleaf lupin variety ‘Belozerny 110’. The seeds of the lupin-oat mixture were ozonized at a dose of 5.0 mg/m3 for 15 minutes and 30 minutes using an RIOS-10(20)-0.5 ozonizer. For comparison, the seeds were treated with the biological product ‘Fitosporin-M’. Ultimately, there were identified the best parameters of the pre-sowing seed treatment of the lupin-oat mixture. On average, over the years of study, pre-sowing seed ozonation greatly improves the germination energy of agricultural crops on 4.8–8.3%, laboratory germination was improved on 3.0–5.0%. The largest green mass productivity of lupin-oat mixture during pre-sowing seed treatment for three years was 26.1 t/ha in the variant with an ozone dose of 5.0 mg/m3 for 15 minutes, which was more than control on 29.2%. In the variant with ozonation time increase to 30 minutes, the average productivity was 23.2 t/ha, which was 14.8% more than in the control. Pre-sowing seed ozonation contributed to dry matter increase on 14.2–19.0%; crude protein yield increased on 32.8–53.2%; crude protein percentage in grain increased on 14.1–16.8%; metabolizable energy increased on 3.7–5,1%; fodder units increased on 4.3–6.5% compared to control. When treating seeds with a biological product ‘Fitosporin-M’, the average productivity was 22.8 t/ha, which was on 12.9% more than control, an increase in dry matter was on 16.6%, an increase in crude protein yield was on 19.6%, an increase in crude protein percentage in grain was on 0.8%, an increase in metabolizable energy was on 1.9%, an increase in fodder units was on 1.0%.

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.

Chemical Description

ABSTRACTA model has been developed to predict the true metabolizable energy (ME,) concentration in forages given to ruminants.The chemical description of forages is based on the concentrations of ash, crude protein, ether extract, sugars and α-glycans, β-glycans and lignin, volatile fatty acids and lactic acid. The model assumes complete fermentation of sugars, α-glycans and lactic acid. The extent of fermentation of β-glycans and crude protein is determined in part by rumen solid-phase outflow rate, which can itself be predicted from dry-matter intake.The model was tested using 121 graminaceous forages whose chemical composition and concentration of metabolizable energy had been measured in the Feedingstuffs Evaluation Unit at the Rowett Research Institute. The agreement between observed and predicted ME, for all classes of forage was nearly always as good as, or better than, the best prediction from single attributes of food chemistry which could only be determined retrospectively and were not consistent even within classes of forage. The model predicts a decline in ME, with increasing rumen solid-phase outflow rate which is determined mainly by the extent of fermentation of β-glycans.

Detailed Work

SUMMARYThe nutritional value of dried poultry excreta was investigated by determining the apparent digestibility of dry matter, organic matter, nitrogen, energy and copper in five diets containing 0 to 100% of this feed. Dried poultry excreta supplied 20·21% apparently digestible crude protein and approximately 1·57 or 1·74 Mcal of metabolizable energy per kg dry matter.The copper in dried poultry excreta was found to be less digestible than the copper in barley. It is concluded that, as far as copper levels are concerned, dried poultry excreta are safe for ruminants, and are a source ofcheap protein. More detailed work is needed to determine the metabolizable energy of the material accurately.

AbstractFour diets, barley/proprietary protein concentrate (B/PC), barley/maize gluten (B/MG), barley/rapeseed meal (B/RSM) and wheat/'rapeseed meal (W/RSM) were formulated to contain 165 g crude protein and 13·0 MJ metabolizable energy per kg dry matter. In experiment 1, all four diets were offered ad libitum to Charolais × Friesian bulls from 187 kg live weight to slaughter at about 488 kg live weight. In experiment 2, the B/PC and B/RSM were offered ad libitum to Charolais × (Hereford × Friesian) bulls from 222 kg live weight to slaughter at about 491 kg live weight. There were no significant differences between treatments in daily live-weight gain, percentage fat and lean in the live animal, slaughter weight or days on experiment in either experiment. In experiment 1, the carcasses from bulls given B/PC were 14 kg heavier than carcasses from bulls given W/RSM (P<0·05), but only 10 and 7 kg heavier than from bulls given B/MG and B/RSM respectively (P<0·05). The killing-out proportion of bulls given B/PC was significantly greater (P<0·05) than bulls given B/RSM. In experiment 2, carcass weights were similar but the killing-out proportion of bulls given B/PC were again greater (P < 0·001). It is concluded that B/MG and B/RSM were as effective as B/PC as finishing diets and that wheat can be successfully substituted for barley, when offered with rapeseed meal.

On Farm

Over a period of seven years farmers participated in trials in which common vetch (Vicia sativa (V)) or chickling (Lathyrus sativus (C)) replaced the fallow in a barley (Hordeum vulgare)–fallow rotation (F) or were introduced into continuous barley cropping (B) – giving a total of four rotations, B–F, B–B, B–V and B–C. Trials on 4 ha, 2 ha per phase of each rotation, were replicated on 6–8 farms. Some vetch and chickling crops were grazed in spring. Mean seven-year dry matter yields were 2.91 t ha−1 for B–F, 4.82 t for B–B, 5.02 t for B–C and 5.32 t for B–V; total crude protein outputs were twice as high from rotations including legumes; and the B–V rotation yielded most metabolizable energy. Realizing the benefit, farmers started to adopt vetch. In 1991 three farmers were growing vetch on 7 ha but by 1997 174 farmers in 15 villages were growing vetch on 420 ha. Forage legumes will not, however, become more widely grown until inexpensive and efficient mechanized methods of harvesting the mature crop are available in order to avoid the high cost of hand labour. Drought and cold tolerance, early maturation and high harvest index may also enhance farmers' interest in forage legumes.

SUMMARYFrom 6 weeks before calving to the end of lactation 2 groups of 8 cows were fed a ration incorporating a dairy nut containing 29 g/kg urea or an isocaloric isonitrogenous nut containing fish-meal and groundnut. During the 18 weeks after calving, concentrates were fed to appetite. 305-d yields of milk (7023 and 5796 kg) and lactose (345.7 and 273.4 kg) were significantly lower in the urea-fed cows (P< 0·05). Intakes of dry matter, metabolizable energy and digestible crude protein were similar in both groups until 18 weeks after calving when feeding according to yield commenced, but by 6 weeks after calving the urea-fed cows lost only 5% of their immediate post-calving weight compared with 7% in the controls. There was no evidence of ammonia toxicity in the urea-fed cows. Blood glucose concentrations were similar in both groups, but higher serum urea concentrations in the urea-fed cows suggested that there was poor utilization of ingested N. A model proposed by Royet al.(1977) has been used to calculate the requirements of rumen-degradable protein and undegraded protein (UDP) of the 2 groups from their energy intakes and milk yields. Between 4 and 11 weeks post-calving, dietary requirement for UDP closely matched intake of UDP. It is concluded that UDP intake was a major factor in determining the peak milk yield. Mechanisms by which the degradability of the dietary protein might influence milk yield are discussed.

Moringa oleifera is a plant that has high nutritional content. Post-harvest treatment take effect in improving product quality. This study was carried out to evaluate nutrient and antioxidant activity of steam blanched moringa oleifera leaves. Sample of moringa oleifera were prepared where the temperature 80°C in ±5 minutes for the steam blanched. The fresh M. oleifera and steam blanched M. oleifera leaves dried at 60°C were analyzed for their proximate, mineral, total phenol, total flavonoid, and antioxidant activity contents. The analysis revealed that steam blanched leaves contained more dry matter, crude protein, crude fat, phenolic total, and flavonoid than unblanched leaves. Therefore, its less fibre and mineral. This study showed steam blanching can serve as alternative post-harvest treatment to increase nutritional value of moringa oleifera leaves.

The research and economic experiment aimed at determining the most effective ratio of milk and vegetable protein in whole milk replacers WMR. It was carried out in four groups of calves with an initial live weight of 39.2–41.2 kg at the age of 10–30 days. The research has shown that WMR No. 1 consisted of (% by weight): dried whey – 53, vegetable fat – 16, vegetable protein – 30, vitamin-mineral complex – 1, No. 2 – skimmed milk powder – 15, whey powder – 47, vegetable fat – 16, vegetable protein – 21, vitamin- mineral complex – 1.0, No. 3 – 30; 41.5; 16.0; 11.5; 1.0. The ratio of vegetable and milk protein in the experimental WMR is made: 46 : 54; 37 : 63; 27.5 : 72.5 respectively. 1 kg of dairy product contained: 16.9 MJ of metabolizable energy and 196-200 g of crude protein. There was no significant difference in the consumption of crude protein between the groups. This indicator ranged within 309–317 g. The raw fat level in 1 kg of dry matter of diets for young experimental groups ranged within 186.9-190.1 g, concentration of metabolizable energy in dry matter of diet in experimental groups is made 17.48–18.02 MJ. 12.4–12.8 g of digestible protein accounted for 1 kg of metabolizable energy. It was established that the total protein content in blood serum of animals in experimental groups ranged within 45.3–50.7 g/l, which is 7.1–19.9 % higher than the reference value. As for sugar level in blood, one can trace the metabolic activity of carbohydrate metabolism of experimental calves’ body. Feeding young animals with milk replacer promoted the increase of glucose level by 5.7–17.1 % in comparison with the coevals of the control group. As a result, it was determined that in control group the whole milk in diets allowed to obtain higher average daily weight gain of 565, and in the experimental groups – 435–505 g, which is 11.2–23.0 % less. The research has shown that despite of higher body weight gain in the experimental group IV, the lower cost of WMR in group II allowed to reduce the diet cost by 26.5–39.2 % and the cost price of weight gain by 18.0–29.5 % compared with animals of the control, III and IV experimental groups. Key words: feed, WMR, young cattle, performance, economic efficiency.

ABSTRACTFour diets containing 9·6 MJ metabolizable energy (ME) per kg dry matter (DM) (LMEC), and four diets containing 11·3 MJ/kg DM (HMEC) were formulated. One diet of each ME concentration contained 90 g crude protein (CP) per kg DM and served as a negative control (NC). In the three other diets of each ME concentration, the level of CP was raised to 140 g/kg DM by inclusion of poultry litter (PL), non-protein nitrogen (NPN) or fish meal (FM). These diets were examined in a digestion and N balance trial and in a feeding trial.For the NC, PL, NPN and FM subtreatments of the LMEC diets, DM intakes were 107·1, 112·4, 100·6 and 130·2 g/kg M075 respectively; digestibility coefficients of organic matter (OM) were 0·64, 0·70, 0·67 and 0·71 respectively; and N retention 0·40, 0·76, 0·53 and 1·21 g/kg M075 respectively. For the respective subtreatments of the HMEC diets, the values were: 100·4, 119·4, 109·3, 107·5 for DM intake; 0·64, 0·73, 0·73, 0·73 for digestibility coefficients of OM and 0·40, 0·87, 1·06 and 1·03 g/kg M075 for N retention.Daily gain on the respective diets in the first 130 days of the feeding trial was 0·85, 0·90, 0·91, 1·04 kg for the LMEC and 1·09, 1·21, 119, 1·24 kg for the HMEC diets, and from the 131st day to slaughter was 0·98, 1·02, 100, 1·08 kg for the LMEC and 1·03, 1·02, 1·07, 1·05 kg for the HMEC diets respectively. Daily carcass gain was 0·49, 0·51, 0·51, 0·53 kg for the LMEC and 0·55, 0·59, 0·59, 0·60 kg for the HMEC diets, respectively.The relationship between ME concentration in the diet and source of CP is discussed.

ABSTRACTDuring weeks 3 to 26 of lactation, two groups of 24 cows were offered either a 60:40 (high) or a 40:60 (low) ratio of concentrate dry matter:silage dry matter. The 40:60 diet was restricted to give the same daily metabolizable energy and crude protein intake. The hooves of half the cows on each diet were trimmed prior to the experiment, the other half remaining untrimmed. The high concentrate ratio significantly increased locomotion score (high scores indicating poorer locomotion), and the number and duration of clinical cases of lameness. Trimming of hooves significantly reduced the number and diiration of clinical cases. Hoof growth was significantly increased by trimming. Hoof hardness was significantly reduced by the high concentrate ratio. The low concentrate ratio had 8/24 cows lame for an average of 3·3 weeks compared with 11 cows for 3·9 weeks on the high ratio. There were 7/24 trimmed cows lame for 3·1 weeks compared with 12 untrimmed cows lame for 4·2 weeks. The main hoof lesions were solar ulcers and heel erosion. There was no significant effect on milk yield, but milk protein was signficantly increased by the high concentrate ratio. Condition score was significantly negatively correlated with locomotion score.
