Annual variation in the feeding value of barley straw (Hordeum vulgare L. subsp. vulgare) is economically significant in the Mediterranean region. The relationship between the feeding value for sheep of several winter-planted barley cultivars and monthly meteorological data was analysed at Tel Hadya, northwest Syria (mean annual precipitation 330 mm) in 11 years. Indicators of feeding value included contents of neutral detergent fibre, acid detergent fibre and nitrogen (11 years), voluntary straw intake by sheep (10 years), voluntary digestible organic matter intake (9 years), in sacco dry matter loss and lignin content (8 years), in vitro digestibility (7 years) and in vitro gas production (6 years). Monthly meteorological data included total precipitation, mean minimum and mean maximum air temperatures.Conditions likely to decrease grain yield tended to increase the feeding value of straw. Low mean minimum temperature in February, low precipitation in January, February, March and April, and high mean maximum temperature in March, April and May increased one or more indicators of straw feeding value (by both bivariate and multiple regression, P<0·05). Precipitation before January affected grain and straw yield but had little effect on the feeding value of straw.Genotype × year interactions had a meteorological component; the superior feeding value of the straw of locally-adapted cultivars v. exotic cultivars was only seen in years with cool or wet springs. This has implications for the genetic selection of crops with better straw feeding value.Models based on monthly precipitation and temperature, calibrated for locations in the Mediterranean region, can predict the nutritive value of straw and aid the planning of rations for small ruminants.

This paper describes the clinical, laboratory and anatomopathologic findings of sheep affected by abomasum compaction. Clinically, the presence of a firm structure located in the abomasal region stands out. The hematology and ruminal fluid analyze revealed neutrofilia with regenerative left shift, hyperfibrinogenimia, fauna and flora impairment and chloride concentration of (39,33 mEq/L) respectively. Macroscopically, a distended and compacted abomasum was observed with the presence of type IV ulcers and diffuse serofibrinous peritonitis. These results confirm the severity of the abomasum compaction in small ruminants. Therefore, guidelines related to animal feed management practices, especially in times of drought are necessary to reduce the occurency of this disease.

SUMMARYThe establishment of leys for biomass production during the winter months could be an alternative feed resource of low cost for small ruminants in Mediterranean basin. For this purpose, an experiment was carried out with six plant species mixtures (PSM) that were cut up to seven times from seeding. The results showed that all the PSM had their highest growth at the 2nd cut withFestuca arundinacea,Lolium perenne,Dactylis glomerata,Trifolium repens(FLDT) being superior as the dry matter production concerns compared with the PSM that gave seven cuts. The crude protein and the ether extracts contents in all the PSM decreased from the 1st to the last cut, while that of NDF and ADF increased. The concentrations of myristic, palmitic, stearic, oleic and linoleic acid increased in all the PSMs from the 2nd to the 5th cut, while the opposite was observed for the α-linolenic acid content. The concentration of α-linolenic acid was higher in the FLDT PSM when compared to others during all cuts. Taking into account all the examined parameters together, the FLDT seems to be superior to the other PSMs as animal feed for small ruminants, particularly during the period where there is no available grass from natural grasslands.

Gastrointestinal nematodes are considered one of the most important sanitary problems affecting ruminants globally; whether parasitizing alone or acting with other pathogens, they are responsible for severe economic losses related to animal husbandry. Endoparasites in small ruminants are usually controlled with anti-helminthic drugs. However, certain strains of endoparasites are resistant to such drugs. Supplementation of the diet with protein-rich foods is one strategy for reducing the negative impact of gastrointestinal parasites. Cratylia argentea has anthelmintic properties and other characteristics that favor its use as an animal feed supplement. In the present study, we subdivided crossbred lambs into homogeneous groups and fed them C. argentea (G1), C. argentea plus Brachiaria spp. (G2), or Brachiaria spp. (G3) only. The animals in group G1 had a lower average number of eggs per gram of feces (EPG) at Day 42 (p < 0.05), and the average count was ten times lower than that in the control at the last evaluated time-point (Day 56). The animals exhibited linear weight gain, and those in group G1 gained the most weight. The combined use of drugs and plants containing bioactive compounds can minimize the evolution of multidrug resistance, prolonging the efficacy of the drugs. The FAMACHA® score showed little variation during the experiment (p > 0.05), indicating the absence of anemia and normal globular volume. This reinforces the importance of the measurement of EPG; this is a quantitative method and does not depend on the subjective interpretation of the results.

Physical And Chemical

The steady rise in emissions from burning fossil fuels has caused increasing concern about their environmental impact. Lignocellulosic biomass can produce alternatives for gasoline and diesel by thermal conversion. Sorghum is used for animal feed since the feed value of its grain is similar to corn. The grain has more protein and fat than corn, but is lower in vitamin A. When compared with corn on a per pound basis grain sorghum feeding value ranges from 90% to nearly equal to corn. The grain is highly palatable to livestock, and intake seldom limits livestock productivity. Sorghum bagasse is the residue of sorghum after milling. The present work had the objective of characterizing sorghum bagasse for energetic use, especially to produce bio-oil by fast pyrolysis. The first step in pyrolysis process is the biomass characterization, since some kinds of particles are not suitable to be processed and need a previous preparation. For sorghum bagasse the performed physical analyses were: size distribution and medium diameter, and solids true density; the main chemical analyses were: ultimate analysis, proximate analysis, chemical composition and gross calorific value.

Measurement Results

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.
