Effect of administration of rumen fungi on production performance of lactating buffaloes

Anaerobic fungi were orally dosed to lactating buffaloes to study their effect on the digestibility of a diet (composed of 50% wheat straw and 50% concentrate along with six kg maize green/animal/day), rumen fermentation patterns and milk production. Group I (control) was administered with fungus-free anaerobic broth, while group II and III were administered with Orpinomyces sp. C-14 or Piromyces sp. WNG-12 (250 ml; 3-5 days of growth/animal/ week), respectively. Milk production was higher in group II and III (8.42 and 8.48 kg/d) than in the control (8.03 kg/d) with virtually the same feed intake (i.e. 11.50 and 10.62 and 11.79 kg, respectively). There was an increase of 6% fat-corrected milk yield/animal/day in group II and III, respectively compared to the control. The milk fat was higher in the fungal culture administered groups than in the control group. The digestibility of dry matter, crude protein, neutral detergent fibre, acid detergent fibre, cellulose and digestible energy also increased significantly in group II and III. The pH and ammonia nitrogen were lower, whereas total volatile fatty acids, total nitrogen, trichloroacid precipitable nitrogen and number of zoospores/ml of rumen liquor were higher in group II and III when compared to the control. Hence, it can be stated that rumen fungi can be used as a direct-fed microbial in lactating buffaloes, to enhance the digestibility of wheat straw based diets leading to higher production.

This paper shows the results of production and chemical composition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

The study was conducted on sows (hybrids of wbp × pbz breeds) and their offspring (until day 75 of life) kept on a farm. The aim of the experiment was to compare the effects of different sources of selenium (Se) on the production performance of the animals, Se content in their blood, the level of Se in sow’s colostrum, as well as Gpx, haptoglobin and immunoglobulin levels in the serum of sows and their offspring. Experimental feed mixtures for pregnant sows (LP), lactating sows (LK) and piglets (prestarter and starter) in each treatment had an identical basic composition, differing only in the type of selenium forms. Group I received a mineral form of Se in an amount of 0.2 mg/kg; group II received a mixture of a Se amino acid chelate and the mineral form of Se (0.1 mg/kg of each); group III received a Se amino acid chelate (0.2 mg/kg), and group IV received Se-enriched yeasts (0.2 mg/kg). Beneficial effects of the organic forms of Se were evident already in the lactation period. Sows, especially those from group II receiving 0.2 mg/kg of organic Se, had a higher feed intake, which was related to a higher milk production during lactation. As a result, on the weaning day, piglets from this group were significantly heavier than the other piglets. After weaning, as well, the piglets in this group were significantly heavier. These results were confirmed by parameters of blood serum and whey colostrum. Selenium as a chelate was more available than the mineral and enriched yeast forms. For this reason, the animals receiving the chelate were healthier (fewer inflammations were noted). The animals in this group also showed a better feed conversion compared with the others. The Gpx level in sows’ serum varied depending on the treatment. The highest level of this parameter was determined in sows from group III (receiving 0.2 mg/kg of organic Se), and it differed significantly from its value in the control group. The results showed that the Gpx level was related to the Se concentration in blood serum, which was also confirmed by a higher production of selenocysteine (a part of Gpx). Cells of the animals from this group were better protected against free radicals. Administration of 0.1 mg/kg of organic Se positively affects the performance of animals, but the recommended level in feed is 0.2 mg/kg of a selenium-containing amino acid....

The Australian dairy sheep industry is small and mostly based on a natural grass grazing system which can limit productivity. The current study tested different plant oil-infused and rumen protected polyunsaturated fats and their interactions with sire breeds to improve lactation traits and body condition score (BCS) of ewes grazing low quality pastures. It was hypothesised that supplementing lactating ewe diets plant-derived polyunsaturated oils will improve milk production and composition without compromising BCS. Sixty ewes (n=10/treatment) in mid-lactation, balanced by sire breed, parity, milk yield, body condition score, and liveweight were supplemented with: 1) control: wheat-based pellets without oil inclusion; wheat-based pellets including 2) canola oil (CO); 3) rice bran oil (RBO); 4) flaxseed oil (FSO), 5); safflower oil (SFO) and 6) rumen protected fat containing eicosapentaenoic acid and docosahexaenoic acid (RPO).  Except for the control group, all supplementary diets included the same level of 50 ml/kg DM of oil and all diets were isocaloric and isonitrogenous. Experimental animals were grazed in the same paddock with ad libitum access to pasture, hay and water during the 10-week study. RPO was the most effective diet that enhanced milk, fat and protein yields by approximately 30, 13, and 31% respectively (P<0.0001). Significant increase in milk production was also observed in CO, RBO, and SFO (P<0.0001). Breed significantly influenced animal performance with higher milk yield recorded for crossbred Awassi x East Friesian (AW x EF) (578 g/day) vs purebred Awassi (452 g/day) (P<0.0001). This study provides empirical evidence for the use of rumen-protected and plant-derived oil-infused pellets as supplements under low quality pasture grazing conditions, to improve production performance of purebred Awassi and crossbred AW x EF ewes.

A study was conducted on samples of raw sheep milk and rennet cheese produced from it. The milk was obtained from ewes of the coloured variety of Polish Merino, from February to April. The sheep were housed indoors and fed preserved roughage and a mixture of concentrate feeds. Three feeding groups were established: group I ‒ control, fed without the addition of herbs to the concentrate feed, and groups II and III, in which a herb mixture was added to the concentrate feed in the amount of 10 and 20 g/sheep/day, respectively. Six experimental batches of bundz rennet cheese were made from the milk, and the effect of the addition of herbs to the diet on the lipid profile of the milk and cheese was analysed. The results indicated that the addition of herbs to the winter diet of sheep in the amount of 10 and 20 g/sheep/day significantly increased the content of the acid C4:0 in the raw milk used for cheese making, by 11.5% and 20.0%, respectively (P≤0.01), relative to the control group. C4:0 content in the raw milk was also increased in group III by 7.6% compared to group II (P≤0.05). The herbs had no statistically confirmed effect on other parameters of the health-promoting quality of the milk fat and the rennet cheese. In the cheese fat from group I produced from sheep milk obtained in the period from 69 to 137 days of lactation, there was an increase in the content of SFA and a decrease in UFA during the course of the experiment. The addition of herbs to the concentrate feed of the sheep improved the fatty acid profile of the fat of bundz cheese made from milk obtained from the 97th day of lactation. The experimental factor also reduced the cholesterol content in the raw milk in group II by 26.8% and in group III by 21.2% (P≤0.01) compared to group I. It did not affect the content of this lipid in rennet cheese.

Crude fibers (CF) take a special place in the growing rabbit`s nutrition. In depend on their origin and composition, CF have digestibility 17- 25% in the roughages and up to 40-50% in the green and concentrate feeds. They are very important in the regulation of the processes of both digestibility and bacterial synthesis. The optimal CF quantity for growing rabbits is 12-15%. Alfalfa hay is preferred source of CF for rabbits, but it is too expensive. But, there are other sources of CF which are more suitable because of their price are lower. The aim of the present study was to investigate the effect of different sources of CF in the mixed rations for rabbits on blood biochemical changes, Volatile Fatty Acids (VFA) production in the ceacum and some fermentative parameters. In this respect we have interest to study the next sources of crude fibers: dry distillers` grain of wheat (DDGSw), produced by Bulgarian firm as a source except for crude fiber - 13% and crude protein (CP) also - 32%; meadow hay and as well as wheat straw as main and chipper sources of CF in the growing rabbits diets. Three compound feeds were prepared. All compound feeds contained 20% oats, 15% barley, 16.40%wheat bran, 10% soybean meal, 5% sunflower meal. The main sources of CF for the diets were: 30% Alfalfa hay (control group); 10% DDGSw + 20% meadow hay (Experimental group I, EG I) and 15% DDGSw + 15% wheat straw (Experimental group II, EG II). The obtained results showed that there were no any incidences of digestive disorders in all investigated groups. Improvement of cecal fermentation led to better NGR and FOM. We made conclusion that DDGSw in combine with meadow hay or wheat straw could use as alternative sources of CF for growing rabbits.

To investigate the milk production limiting potential of a diet based on grass silage (40%), hay (15%), dried sugar beet pulp (13%) and grain compound mixture (32%), 28 multiparous cows in early lactation were randomly assigned to two treatment groups: a control group and a group receiving supplementary rumen protected methionine (RPMet) treatment (12 g intestinally available methionine/ cow/day, given 1–120 days postpartum; Smartamine™; RPAN’s technology). The diet was formulated to meet the requirements for protein and net energy. RPMet supplementation had no significant effect on DMI (kg/cow/day), milk dry mass, milk lactose and milk urea contents. Responses for mean daily milk yield, mean milk fat and milk protein yields were significantly higher (P < 0.05) in cows supplied with RPMet than in controls. Mean daily milk yield, milk protein and milk fat yields increased by 2.4 kg, 108 g and 124 g, respectively. The mean daily milk protein and casein contents were increased by 1.8 g and 0.9 g and milk fat content by 1.2 g in 1 kg of milk, respectively. The results suggest that in cows fed grass silage and a grain compound mixture milk production is limited by methionine insufficiency, but milk production performance can be increased significantly by the addition of RPMet to the diet.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.
