The present study was conducted to probe out the nutritive losses caused by Rhyzopertha dominica (F.) and Trogoderma granarium (Everts) were quantified in six rice genotypes (KSK-434, KSK-282, Irri-6, Shaheen basmati, Basmati 385 and Chenab basmati). Percent crude protein, ash and moisture content were measured for qualitative losses, while for quantitative losses, frass weight and weight loss were examined after infestation period of 90 days of. Highest weight losses (25.76%) and (15.37%) were observed in KSK-434 by infestation of R. dominica and T. granarium, respectively, compared with un-infested grains after a storage period of 90 days. Highest frass weight (8.57 g) was recorded for KSK-434 while relatively low frass weight (4.16 g) was recorded for Basmati 385 by infestation of R. dominica. Relatively low frass weights of 5.67, 4.46 and 4.01 g were recorded in KSK-434, Chenab basmati and Shaheen basmati, respectively by attack of T. granarium. Highest percentage moisture values (14.03 and 11.24%) were recorded for KSK-434 by infestations of both test insects compared to non-infested (controls). Percent crude protein was decreased (from 6.97% to the 4.92%) due to infestation of R. dominica values by strain were KSK-434 (4.54%), Shaheen basmati (4.89%) and chenab basmati (4.92%). In the case of T. granarium infestation, almost all the varieties sustained the low protein contents except KSK-434 (5.02%) and Basmiti 385 (5.17%) and Shaheen basmati, protein contents loss comparable to non-infested control (7.09%). Ash content was high in genotype KSK- 282 (0.68 %) compared to control. KSK-434 and Chenab basmati had relatively low ash percentage due to high infestation of T. granarium. R. dominica attack produced the highest percent ash content (0.66%) in KSK-282 and the least (0.44%) in KSK- 434. The tested rice genotypes were more susceptible to R. dominica than T. granarium among the different genotypes of selected cereals.

Pear fruits have a high biological and nutritional value; however, they are perishable products, storage of which is accompanied by certain difficulties. You can preserve the quality of fresh pears through the use of various packaging methods, among which the use of polyethylene liners is effective. The article presents the results of studies of weight loss and yield of pears during storage, depending on the variety and method of packaging. Conferencia, Noiabrska, and Osnovianska pears of the highest and first commodity varieties were pre-cooled and packed in wooden boxes №3, with a capacity of up to 25 kg (“control” option) and in boxes with a plastic bag liner inserted inside the package 45–50 μm followed by sealing (option “box with a polyethylene liner”). Pear fruits were stored for four months at a temperature of 0 ... + 3 ± 1 ºС and relative humidity of 92% ± 2%. Fruit weight losses were determined by the method of weighing fixed samples, the yield of marketable products - according to DSTU 8326:2015. It was found that during the storage period of pear fruits, their weight loss was 2.3–5%, depending on the variety and method of packaging. In terms of pomological varieties, according to average data, the highest weight loss was pears of the Osnovianska variety – 2.6%. The use of polyethylene liners during the storage of pears helped to reduce losses by 0.5–2.3% depending on the variety and duration of storage. It was found that in the conditions of free air access the share of standard products was 78.6–88.3% with the minimum value in the fruits of Conference and the maximum in the fruits of Noiabrska Moldova. It is proved that packing pear fruits in wooden boxes with polyethylene inserts caused an increase in the yield of marketable products to 90.2–98.4%, a decrease in the share of non-standard products to 1.6–7.0%, and waste to 2.8%. The weight loss of pear fruits of the Noiabrska Moldova variety was 0.3–1.5 lower compared to similar indicators of other varieties. The fruits of the same variety recorded a higher yield of marketable products – 88.3–98.4% depending on the method of storage.

ABSTRACTEighty-eight first-litter sows were used in a factorial experiment to examine the effects of energy and protein intakes during lactation on subsequent performance. Some received either 45 MJ (E,) or 60 to 63 MJ (E2) digestible energy per day and either 508 to 511 (P,) or 703 to 815 (P2) g crude protein per day during a 28-day lactation.Sows on the E2P2 treatment lost less body weight during lactation than sows on the other three treatments (P < 0·05). Average live-weight losses during lactation were 21·8, 20·8, 17·8 and 9·6 kg for the E1P1, E1P2, E2P1, and E2P2 sows, respectively. The corresponding reductions in backfat measurements during lactation were 5·5, 7·9, 3·2 and 4·0 mm. Backfat losses were greater for sows given either moderate energy intakes or high protein intakes (P < 0·01).Neither protein intake nor energy intake during lactation affected subsequent ovulation rate, but piglets sucking sows given high protein intakes grew faster, particularly during the last week of lactation, than piglets sucking sows receiving low protein intakes (P < 0·05).Within 8 days of weaning, more sows given high intakes of protein during lactation exhibited oestrus than did sows which received lower intakes of protein (27/44 v. 14/44, x2 = 7·7, P < 0·01). Protein intake during lactation affected the nitrogen balance of sows in a similar way. The nitrogen balances were estimated during the 3rd week of lactation, and for sows given rations E1P1, E1P2, E2P1, and E2P2were -20·2, -11·5, -17·5 and -7·2 g/day respectively.

Three cultivars ofVigna radiata, namely, NM-92, NM-98, and NM-06, were analyzed for their proximate composition. The samples were also tested by HPLC for amino acid content. The data showed that all the varieties had same moisture level. The maximum ash content (4.29%) was present in NM-92, and crude fat (2.26%) was highest in NM-98 while NM-06 contained maximum amount of crude protein. About eighteen types of amino acids were detected in each of the three varieties. Acidic amino acids, that is, aspartic and glutamic acids, were in considerable amount ranged from 13 to 23% followed by leucine, isoleucine, alanine, valine, lysine, phenyl alanine, serine, and arginine which fell in the range of 3–8% of total protein. The maximum amount (13.00 and 22.80%) of aspartic and glutamic acids was present in NM-98. Similarly arginine (6.83%) and serine (5.45%) were also in highest amount in this variety. Leucine (7.46%) was maximum in NM-92 variety. NM-06 contained almost all the amino acids in lesser quantity except for few like threonine, proline, glycine, and alanine. It was concluded from the present study that varieties were of different nutritional value and HPLC was a sensitive method for amino acids determination. Antioxidant activities of all three varieties were also assayed and showed significant results.

Sphenostylis Stenocarpa

The nutritional and mycoflora changes in dried African yam beans (Sphenostylis stenocarpa) were investigated during a storage period of twenty weeks. The result of the proximate analysis (g/100 g) showed that the following moisture content decreased from 11.15-9.80, fat 1.25-0.49, crude fibre 6.18-2.64, crude protein 77.92-62.14 while the ash content increased from 3.20-3.78, carbohydrate content 0.36-18.32. The mineral analysis (mg/100 g) showed a decrease in all parameters investigated, sodium (Na) 2.57-1.35, potassium (K) 42.26-31.75, calcium (Ca) 21.45-12.56, magnesium (Mg) 27.75-20.72, iron (Fe) 0.25-0.12, zinc (Zn) 0.06-0.05, copper (Cu) 0.03-0.03, phosphorus (P) 32.08-22.03, manganese (Mn) 0.11-0.06, chromium (Cr) 0.002-0.001. Lead (Pb), cadmium (Cd) and nickel (Ni) were not detected. Five fungi comprising four genera were isolated using direct plating, washing and dilution methods on Potato Dextrose Agar (PDA), and identified using their cultural and morphological features with reference to standard procedures. The fungi isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Mucor sp. and Phytophthora palmivora. It can be concluded that storage encourages proliferation of mycoflora thereby leading to reduction in the nutritional and mineral composition of the stored sample.

For ruminants, especially high-yielding animals in addition to the complete supply of animals with protein, its digestibility in the rumen is important. With low protein digestibility in the rumen, the released ammonia will be more effectively used by the rumen microflora, and the undigestible protein in the subsequent sections of the digestive tract can serve as a source of amino acids for the body. The use of concentrate mixtures with the inclusion of local, affordable and cheaper grain feeds, in particular a high-energy and protein ingredient- rapeseed presscake makes it possible to increase the milk productivity of cows throughout lactation. These presscakes are well balanced in their amino acid composition and belong to feeds whose protein has a low degree of digestibility in the rumen. The purpose of the researches was to study the digestibility of nutrients and milk productivity of cows when using the concentrate mixture with the inclusion of rapeseed presscake. In the scientific and economic experiment has been carried out on lactating cows, where the cows of the experimental group in the concentrate mixture of peas has been replaced with rapeseed presscake the digestibility of nutrients in the ration, energy metabolism and milk productivity have been studied. Studies have shown that almost all the nutrients were significantly better digested by the animals of the experimental group. Energy in milk was more allocated by cows of the experimental group by 6,29 MJ. From cows of the experimental group for 100 and 305 days of lactation has been obtained more milk by 6,27 and 7,06 %, respectively, than from control herdmates. The biochemical parameters of blood were within the limits of the physiological norm in animals of both groups. Thus, the replacement of peas with rapeseed presscake in the concentrate mixture did not have a negative influence on the metabolic processes and helped to increase the milk productivity of cows.

SUMMARYIn a factorial experiment the effect of two protein intakes and three patterns of feeding in the second pregnancy of 48 Large White x Wessex Saddleback sows was examined. The high protein (HP) diet (19·5% crude protein) contained 15% white fish meal. The low protein (LP) diet (10·5% crude protein) contained cereal protein only. Nutrient components of the diets differed in protein only. The pattern treatments involved allowances of 1·8 kg (L), 2·7 kg (C) and 3·6 kg (H) per day, the three pregnancy patterns being HL, C and LH with the changeovers made from the 49th to the 63rd day post coitum (p.c). Sows on the three pattern treatments received the same total amount of feed from 0–112 days p.c. and were treated alike at farrowing and during lactation.Fertility and parturition results were similar for all treatments, but the number of piglets alive after birth (when weighed) was least for LP sows on the HL pattern. At 3 weeks of age the size and weight of litters on HP sows were significantly greater than those on LP sows (P < 0·05 and < 0·001 respectively). More piglets were weaned by HP sows than LP sows (P < 0·05). HP sows gained more weight in pregnancy (P < 0·001) which was slightly longer, and lost more weight in lactation (P < 0·05) than LP sows.The HL pattern of feeding was associated with smaller live weight gains in pregnancy than the LH pattern (P < 0·001) and the total birth weight of HL litters was lighter than LH (P < 0·05), mean piglet weights being similar. Lactation performance was unaffected by pattern treatment.The main conclusion is that a low intake, particularly during the latter half of pregnancy, of protein which is of vegetable origin, is associated with decreased viability of the piglets at birth and in early suckling life, and with lower capacity of the sows for milk production.

Gastrointestinal Parasitism

Lactating rats experience a breakdown of immunity to parasites, i.e. they carry larger worm burdens after re-infection compared to their non-lactating counterparts. Feeding high-protein foods to lactating rats results in reduced worm burdens. This could be attributed to changes in gastrointestinal environment or to overcoming effects of nutrient scarcity on host immunity. The latter hypothesis was addressed through a manipulation of nutrient demand by manipulating litter size. Twenty-three rats were immunized prior to mating and re-infected on day 2 of lactation with 1600 infective Nippostrongylus brasiliensis larvae. From parturition onwards, rats received ad libitum a low-protein food (100 g crude protein/kg). Litter sizes were standardised to nine (LS9), six (LS6) or three (LS3) pups, by day 2 of lactation. After a further 10 d, LS9 and LS6 rats carried more worms than LS3 rats. However, feeding treatments did not affect concentrations of mucosal inflammatory cells. Achieved feed intake did not differ consistently between the treatment groups. However, LS9 and LS6 rats lost weight, whilst LS3 rats gained weight during lactation. The results support the view that resistance to N. brasiliensis is sensitive to changes in nutrient demand, and the improved resistance to N. brasiliensis is likely due to effects of overcoming nutrient scarcity on host immunity.

The diets contained 23% crude protein and 3100 Kcal ME/kg diet. Blood meal slightly reduced weight gain and feed intake but compared favourably with fish meal and chicken offal meal in efficiency of feed utilization. Parboiling of the blood slightly (P>0.05) depressed the performance of the pigs;even when the pigs had the same feed intake.. Fish meal increased (P<0.05) serum total protein and serum albumin levels.This study indicated that early weaned pigs fed soybean based diets supplemented with chicken offal meal and blood meal gave similar performance to those fed diet supplemented with fish meal.

In a laboratory study, the results of ensiling caged layer poultry waste with carbohydrate source to enhance its usefulness as feed ingredient for livestock were reported. Poultry waste (20%) mixed with cassava or sorghum flour was ensiled in test-tube silos and sampled at intervals during a 14-day storage period. In both mixtures, the dry matter (DM), crude protein (CP) and pH values were significantly. in Nigeria, poultry waste was affected (P<0.05) with time after ensiling. The DM values were higher (P<0.05) on day 10 than on day 0,5 or 14. The poultry waste-sorghum mixture increased in CP level (P<0.05) from 8.0% on day O to 9.1% on day 14 while in the  cassava mixture CP increased from 7.0% on day  7.6% on day 10. There was a drop in pH from 6.4 to 4.6 in both mixtures at the end of the storage period. The results showed that ensiling cassava or sorghum flour with poultry waste enriched the nitrogen content of the mixture thereby enhancing its usefulness  as livestock feed.
