In 1989, records showed a population of approximate 210.000, while today just 14 000 buffalo remain. In the past, buffalo played an essential role in the economy of many peasant homesteads. Contemporary buffalo farms have not evolved much regarding size, most farms exploit an average of 1.6 head, extremely low, as data from the Association of buffalo breeders in Transylvania show. Too little research is done. The actual milk yields and reproductive traits need to be analysed, as improvement is needed. This present study aims to showcase the dramatically reduced population and farm size and milk yields. Data was obtained from the Association, regarding buffalo registered for control. The information was analysed and conclusions derived. Most facilities have been indicated as homesteads with very few animals. 126 units have been grouped in farm sizes of 1-2, 3-4 and over 5 animals. Production data have higher values in units with over 5 buffalo. It is shown that extra support is needed for conserving, and expanding the numbers of buffalo reared. Production levels are low, need for improvement and genetic research is high.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The first series was not treated with HCl (N0 = 12), while the second series was treated with HCl 1N (N1 = 12) to adjust its pH to about 2. Then all samples (series 1 and 2) were subject to a group of microbiological analyzes targeting identification and enumeration of total aerobic mesophilic flora; fecal and total coliforms; Clostridium perfringens; Staphylococcus aureus; Salmonella spp. as well as yeasts and molds. The results revealed that after lowering the pH to about 2, the 2nd series samples were considered of satisfactory quality, with reference to Algerian microbiological standards for livestock feeds. The reduction rates of germs in the 2nd series compared to the 1st series were as follows: total aerobic mesophilic flora (86.45%), total coliforms (96.43%), faecal coliforms (70.41). %), Clostridium perfringens (88.4%), yeast and mold (87.75%).

The aim of this study was to determine the effect of farming management system and breed on the milk yield, and fatty acid composition of the milk from 50 confinement-fed cows that were fed a total mixed ration, and 52 pasture-fed cows grazed together in rangeland. Individual milk samples (N = 102) were collected once in February. Milk from local breed was characterized by a significantly lower milk yield, and somatic cell count, and a higher protein content than the Holstein breed. The fatty acid composition was relatively the same in both breeds. The result showed that farming management system has no significant effect on the milk yield, somatic cell count, and fat contents, while there was a significant effect on protein content and fatty acid composition. The milk of Holstein cows from extensive system was characterized by more favorable fat fractions with significantly lower concentrations of C10:0, C12:0, C14:0, the sum of short and medium chain saturated fatty acids and n-6: n-3 ratio, and also by higher concentration of unsaturated fatty acids and the sum of n-3 than the milk of Holstein from intensive system.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

An in vitro experiment was carried out on five fistulated females for rumen fermentation activity, while 15 males were used for digestibility trials. Treatment with EM caused less cell wall content. GS and CtP had higher feed intake (FI) and digestibility coefficients; the lower was found for JM as well less FI. SBP and JM had a higher pH and NH3 concentration, while they were less for GS and CtP. Those had higher total volatile fatty acids (TVFA's) concentration, percentage of acetate, and acetic to propionic (A/P) ratio. JM had less acetate, A/P and higher propionate and butyrate. Higher gas volume after 24h fermentation was noticed for GS and CtP, they were higher kinetic parameters as well, but they were less methane production and more ME (MJ/kg DM), OMD (%) and microbial protein syntheses. Therefore, in conclusion, feeding Bokashi of GS or CtP to sheep can improve productivity, while using Bokashi of JM should be combined with other feeds.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Artificial intelligence is a computer science sub-field that is materialized by algorithms developed starting from the logical or mathematical models of the cognition, perception and action processes. Globally, large agricultural companies are trying to grasp concepts such as big data, artificial intelligence (AI), machine learning and analysis. These areas have moved rapidly towards the agro-livestock sector too, but most companies have not been prepared to deal thoroughly with these new technologies. It really sounds interesting, but what does it take to take the next steps? The voice of the expert says: “If we really want to have a global impact on food sustainability, production and safety, we need to think about data standards, data sharing, benchmarking and analysis on aggregated data sets. Today, we see farmers who are reluctant to share data with agritech companies that have developed closed systems, which will hinder the evolution of things” (Claudia Roessler, IT specialist, Microsoft).","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Thus, using suitable feeding regimes of cows, fatty acid (FA) profile of milk fats can be improved by increasing the concentration in functional FA (C18:1 trans-11, vaccenic acid; C18:3 n-3, acid linolenic and C18:2 cis-9 trans-11, isomer of conjugated linoleic acid), considered as beneficial for consumer’s health. These suitable feeding regimes of cows aim using green fodder (pastures), preserving the fodder by drying or silage, supplementing the food with fats rich FA polyunsaturated (PUFA) and ensuring an optimal ratio between volume and ration concentrates. Milk yielded from grazing cows shows a considerably higher concentration of functional FA and lipophilic antioxidants (tocopherols, retinol and carotenes) and a lower content of saturated FA compared to that yielded from cows fed in shelter with TMR (total mixed ration). Also, hay-based feed rations, mainly those containing small amounts of concentrates or those supplemented with vegetable fats, ensure a milk yield with a fatty acid profile more favorable for human health and a better oxidative stability of compared to those with feed-based rations on silage or those high in concentrates.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.
