Sheep Milk

The current research was undertaken to use the genetic potential of animals to obtain high-quality dairy products. Single nucleotide polymorphisms (SNPs) in SLC27A3 gene were identified in Zošľachtená valaška sheep using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Correlations between genotypes and milk composition and nutritional value were analysed This study showed that milk from sheep with TT genotype in the SNP4 locus was characterised by higher (p < 0.01) fat and dry matter content and lower lactose concentration, compared to sheep with AA and TA genotypes, respectively. Moreover, it was found that animals with GG genotype in SNP1 produced milk with higher C18:1n9c, C18:1n7t, CLA, and other unsaturated fatty acids (UFAs) content than sheep with TT. Additionally, milk from animals with CC at the SNP3 locus had significantly higher (p < 0.01) levels of UFAs than milk from sheep with other genotypes in the SNP3. In summary, it may be concluded that milk from animals with TT genotype of SNP4 is characterised by higher fat and dry matter content. Whereas, milk from sheep with GG in SNP1 and with CC in SNP3 is characterised by higher content of UFAs, which increases milk value as material for functional food production.

Cutting Height

The goal of this study was to assess the dehydration curve and nutritional value of Tifton 85 bermudagrass at two cutting heights from ground level (4 and 8 cm) during 120 days of storage in a closed shed. The dehydration curve was determined using samples from the entire plant at eight different times. The experimental design consisted of randomized blocks with plots subdivided per times and five replicates. The second step consisted of assessing the nutritional value of the stored Tifton 85 bermudagrass in randomized blocks with plots subdivided per times and two treatments per plot: cutting height of four and eight centimeters from the ground, and five different times for the subplots, with five replicates. Dehydration of Tifton 85 bermudagrass at the two heights occurred in 48 hours, considered an ideal time for hay drying. The dry matter content responded quadratically to the time of storage of the two heights, only differing during baling and after 120 days of storage. Crude protein content had a quadratic behavior in the two cutting heights, with the smallest value after 30 days of storage (107.0 g kg-1) and the largest after 90 days (147.8 g kg-1) in the cutting height of eight centimeters. The ether extract exhibited a quadratic behavior in the two cutting heights, only differing after 90 days of storage. The neutral detergent fiber content had linear positive response according to the time of storage, with no difference between the cutting heights. For the neutral detergent fiber content in the two cutting heights, the quadratic regression model was the best fit to the data, differing between the heights after 30 and 60 days of storage. In vitro dry matter digestibility and in vitro cell wall digestibility values of the stored hay were lower than the values obtained at the time of cutting. Cutting performed at four centimeters from the ground was the most suitable for hay production due to higher dry matter production and nutritional value without difference between bailing treatments. Hay storage caused undesirable changes in the nutritional value, especially in fiber content and in vitro digestibility.

The average data for 2018–2019 are presented for yield, dry matter content in grain-haylage mass, nutritional value of test grain-haylage samples produced from plant mass of white lupin, oat and Sudan grass from single and mixed cenosis of different sowing times. The grain-haylage mass was harvested in the phase of brilliantly ripening lupin bean, milky-waxy ripeness of oats and the end of flowering of the Sudan grass. It’s revealed that variants of the second sowing date — 2 decade of May — have the best yield of grain-haylage mass and its dry matter content. The yield of grain-haylage mass in the best variants of the second sowing period exceeded by 7–8 t/ha. According to the nutritional value of grain silage samples (the content of metabolic energy, crude protein, crude ash and carotene), the best results were obtained in most variants of the first sowing period. In content of the metabolic energy and crude protein of 1 kg of dry matter of grain-haylage, the best were variants of the single-species cenosis of lupine and its mixture with oats of the first sowing period. Variants of single-species sowing of lupine and Sudan grass were distinguished by the content of carotene.

Gas Tight

Legume–grass forage was ensiled two seasons in 25-ton polyvinyl-encased stacks at dry matter (D.M.) levels of 22 to 37% or stored as field-cured hay. The polyvinyl sleeve coverings provided initial gas-tight conditions. High losses occurred in the high D.M. (32 to 37%) silage during the feeding-out period. Silage quality, as indicated by volatile fatty acid ratios, proximate principles, and digestibility coefficients, was not significantly influenced by D.M. content. When cows were fed the lower D.M. (22 to 29%) silages and hay, forage intake was inversely related to its dry matter content. Intake of high D.M. silage appeared abnormally low. Milk yields appeared to be more consistently influenced by small variations in grain intake than forage dry matter intake through both trials. Milk yields from silages were greater than from hay per unit of D.M. intake. Moisture content of forage had no significant effect on milk composition as indicated by percentage of butterfat, solids-not-fat, or protein.

Ad Libitum

Two experiments were carried out, using 36 lactating Holstein cows, to determine the effect of three levels (0, 4.5 and 9.0 kg/day) of alfalfa pellets (AP) on the ad libitum consumption of early and late harvested timothy grass silages of different dry matter (DM) content. Cows consumed significantly more wilted than nonwilted silage DM for both the early and late harvested grass, although milk yields were similar for both groups. For the early harvested, wilted and nonwilted silages, feeding AP did not significantly depress silage DM intake until a level of 9.0 kg/day was reached. Total ration DM intake increased significantly with each increment of AP. With the late harvested silages, AP at the 9.0 kg/day level reduced nonwilted silage DM intake while with the wilted silage each increase of AP significantly lowered silage DM intake. Both the 4.5 and 9.0 kg/day of AP increased total DM consumption with the nonwilted silage but 9.0 kg/day of AP was required to significantly increase total DM intake for cows fed the late harvested, wilted silage. Milk yield and milk composition were not changed by the level of AP supplementation or the type of silage fed.

ABSTRACTForty-four British Friesian, first-lactation heifers were used in a randomized block experiment over a 2-year period to examine the effects of two patterns of concentrate allocation during the post-calving, indoor feeding period. The animals, mean calving date 17 October (s.d. 15 days), were offered concentrates either on a high-low system consisting of 80kg/day for the first 90 days of lactation and thereafter 5-4kg/day, or on a uniform system in which 6-8 kg/day was offered from calving until going to pasture (mean of 182 days). In addition, all animals received access ad libitum to grass silage, with a mean dry-matter content and digestible organic matter in the dry matter value of 218 and 679g/kg respectively. During the 1st year all 22 animals were housed as a single group, but in the 2nd year the animals were housed in individual stalls and silage intakes recorded for all replicates. In each year all animals grazed as a single group at pasture without supplementary concentrates.Total concentrates consumed were 1163 and 1187 (s.e. 19·4)kg for the high-low and uniform treatments respectively. Although the animals on the high-low treatment reached a higher peak milk yield, there were no significant differences in milk yield over the winter period, 3257 and 3311 (s.e. 41·5) kg, or total lactation, 4862 and 4886 (s.e. 80·6)kg, for the high-low and uniform treatments respectively. The animals on the high-low treatment, however, were significantly lighter in body weight at the end of the winter but there was no difference between treatments at the end of lactation. Milk composition data are also presented.

Npk Fertilization

The storage roots of arracacha have high nutritional value, being rich in carbohydrates, minerals, vitamins A and C, and starch of high digestibility. However, in this crop one of the decisive factors for the production of roots with higher nutritional value is the balanced fertilization. The aim of this study was to evaluate the yield and nutritional quality of storage roots of arracacha, grown at increasing levels of NPK fertilization. The experiment was conducted in the randomized blocks design, with eight replications. The treatments consisted of three NPK levels (AD0 = unfertilized cultivation, AD1 = cultivation with 50% of recommended fertilization, and AD2 = cultivation with 100% ofrecommended fertilization). It was observedthat higher levels of NPK fertilization increase the number, size and marketable yield of storage roots of arracachacrop. NPK fertilization also increases the size and contentsof K, Mg, and Mn of storage roots, without interfering with the pulp pH and contentsof protein, Ca, Cu, and Fe. However, when the increase in root size is not accompanied by an increase in dry matter content, the starch, P, and Zn contents of the roots reduce with increasing levels of NPK fertilization.

The objective of the study was to compare the chemical composition and fatty acid profile in ten clinically healthy bulls of similar weight from eight meat cattle breeds. The animals were raised by extensive grazing under the same geographical conditions. Significant differences were observed between the monitored genotypes in terms of the dry matter content, nitrogenous matter and fats (P ≤ 0.05) in the musculus longissimus thoracis. The concentration of fats ranged from 68.5 ± 18.81 g (Galloway cattle) to 171.6 ± 43.3 g (Aberdeen Angus) per kg of dry matter. The total content of unsaturated fatty acids ranged from 20.0 ± 2.25 g (Aberdeen Angus) to 42.4 ± 7.87 g (Gascon); the total sum of monounsaurated fatty acids ranged from 17.0 ± 2.26 g (Aberdeen Angus) to 33.8 ± 3.61 g (Gascon); and the total sum of polyunsaturated fatty acids ranged from 3.0 ± 1.42 g (Aberdeen Angus) to 5.1 ± 3.99 g (Limousin) per 100 g of fat. The total content of n-6 fatty acids ranged from 2.4 ± 1.28 g (Aberdeen Angus) to 4.2 ± 3.59 g (Limousin) and the total content of n-3 fatty acids from 0.5 ± 0.16 g (Salers) to 1.1 ± 0.04 g (Gascon) per 100 g of fat. The properties we studied may predict the biological, dietetic, and culinary value of the meat.

Trifolium Repens L

In 2014-2016 at the Research Institute of Mountain Stockbreeding and Agriculture- Troyan, we followed the change in the qualitative composition of dry biomass from two-component grass mixtures. The grasslands with the mixture of Trifolium repens L. - Poa pratensis L. have the highest crude protein content (151.6 g kg-1 DM), mineral substances (75.6 g kg-1 DM) and crude fat (33.9 g kg-1 DM). The legume grass associated with perennial ryegrass forms forage matter with the highest carbohydrate amount (434.9 g kg-1 DM) and the lowest amount of crude fiber (269.8 g kg-1 DM). The biomass of Lotus corniculatus L. and Festuca rubra L. is the richest in Ca (19.1 g kg-1 DM), and the mixture of blue hybrid alfalfa - cock's foot has the highest dry matter content (909.7 g kg-1 DM). The biomass of blue hybrid alfalfa - cock's foot (16.99 MJ/kg DM) and red clover - meadow fescue (16.96 MJ/kg DM) is with the highest caloric values. Both mixtures have almost identical values regardless of the different botanical composition and the predominant component in the grassland. The mixture of Trifolium pratense L. with Phleum pratense L. has the highest energy nutritional value (FUM - 0.71 kg DM and FUG - 0.66 kg DM), and the biomass of the blue hybrid alfalfa - cock's foot registered the lowest amount of exchange energy (7.30 MJ/kg DM), as well as the smallest number of feed units (FUM - 0.67 kg DM and FUG - 0.61 kg DM) in the dry matter. For the experimental period with the lowest values of gross energy (16.70 MJ/kg DM) are the mixed grasslands of Trifolium repens L.
