AbstractThe aim of the study was to carry out a research on the use of milking robots compared to utilization of milking parlors. There was no such study in literature on the milking farms in Poland and abroad. The presented study, except for scientific knowledge, provides also practical utilization as a good agriculture practice on the farm. Tests were carried out simultaneously in two barns belonging to the same farm. In barn K, milking was used in the rib bone milking parlor, and in barn N with milking robots. The results covering three years of research from 2016 to 2018 were presented. It was concluded that the milk yield of young cows in both barns was almost identical, while in the second and subsequent lactation, cows in barn N had higher yield. In barn N, about 3% more milk was obtained from LKS below 400 thaus. ml−1, compared to barn K. Time of cows’ utilization in both cowsheds was similar, while in barn N the life efficiency of culled cows was higher by about 1,000 kg of milk. The level of deficiency and its structure, due to the number and stage of lactation, were very similar in both barns. In barn N, the uniformity of milk production throughout the year was more even compared to barn K. There were reserves in the use of the milking robot due to the low number of cows per milking stand and the need to better adaptation of milking times to current cow performance. The milking robot improves cow welfare and ensures high milk yield and good cytological quality of milk.

Quality Of Milk

In tropical smallholding, goats are a common source of milk either for sale of self-consumption. Concentrates are commonly use to support milk production during the dry season where many trees shed their leaves and are no longer available for feeding. Silage making might be an adequate technology for using forage trees as quality supplements along the year. Few studies have been conducted with forage tree silages to evaluate the resultant animal performance especially regarding milk production. The objective of the present experiment was to evaluate milk production and quality of milk of goats fed grass and supplemented with grains or forage tree silage.

The study focussed on the Romanian spotted breed-Simmental type was aimed to evaluating the productive potential and some reproductive indices in the period 2013-2015 in Sona farm from Brasov county. The main indicators taken into consideration to analyze the whole herd were the following: milk yield, milk quality, age of first calving, mammary repose and calving interval. Analyzing milk production, this was increasing from 5439 kg in 2013 to 7400 kg in 2015, with an average for the entire period of 6324.33 kg with 4.23% fat and 3.42% protein. Also the fat and protein content have increased over this period, from 4.13 % for fat and 3.25 % for protein in 2013, to 4.34 % and 3.56 respectively in 2015. Analyzing the main indicators of reproduction for a period of three years it was found that calving interval is on average of 401 days and mammary repose is around of 54 days. It is clearly observed that during this period the production is increasing, this shows that cows from the Sona farm records genetic progress regarding qualitative and quantitative milk production. The research has done much to show the productive potential and popularity of the Romanian spotted breed-Simmental type in Transylvania region.

The effect of substituting peas for soybean and canola meals as a protein source in a high-producing dairy herd was studied in 66 Holstein cows, divided into two groups based on stage of lactation, parity, level of milk production and days in milk. Two 18.5% crude protein grain concentrate diets were formulated based on the nutrient analyses of the forages available. The control grain mix contained standard protein sources, principally soybean and canola meal (SBM\CM) while the test grain mix was formulated to contain approximately 25% field peas as the major source of protein. Both grain rations were formulated to the same nutrient specifications and balanced for undegradable protein. The duration of the trial was 6 mo during which grain feeding levels were adjusted monthly based on milk yield. For cows in early lactation, 4% fat-corrected milk yield was higher (P < 0.05) for cows fed pea based concentrates (31.3 kg d−1) than for cows fed SBM\CM supplement (29.7 kg d−1). Fat-corrected milk yield was not affected by source of protein in mid- and late-lactation cows. Fat-corrected milk production was not different (P > 0.05) for cows fed SBM\CM compared with cows fed the pea supplement when cows across all stages of lactation were included in the analyses. Milk fat percent was significantly higher (P < 0.05) for early- and mid-lactation cows fed the pea supplement. The results suggest that peas can be substituted for SBM\CM as a protein source for high-producing dairy cows.

Three trials in dairy cows were carried out to study the effects of replacing grass silage (GS) with wholecrop silage (WCS) made of barley (BS) or wheat (WS) harvested at dough stage with a dry matter (DM) concentration of 300-450 g kg-1. All silages were ensiled using a formic acid based additive 5 l t-1. Milk production responses to energy and protein supplementation of diets were studied. In Exp. 1, BS replaced GS at the rates of 0, 200, 400 or 600 g kg-1 forage DM. Also 10 kg of concentrate containing 0 or 2 kg of rape seed meal was fed. In Exp. 2, barley was harvested at three times (BS1, BS2, BS3) at one week intervals. Barley silages were fed as a mixture with GS (40:60) and in addition BS2 and GS alone. Silages were supplemented with a cereal based farm-made concentrate (FC) or a commercial compound having a lower concentration of starch than FC. In Exp. 3, barley and wheat were harvested at two week intervals, fed as a mixture with GS (40:60) and supplemented with low or high amount of concentrate. The fermentation quality of whole crop silages was good. Weather conditions and maturity affected the proportion of ear in the crop and subsequently the ratio of non-structural carbohydrates to NDF in the silage. The inclusion of WCS depressed diet OM digestibility depending on the digestibility of GS and the proportion of WCS in the diet. However, mixing GS and WCS did not depress intake. Subsequently the use of mixtures maintained or even increased milk yield as compared with GS diet in Exp. 2 and 3. In Exp. 1, higher proportions (400, 600 g kg-1) of BS decreased milk yield. Minor effects of growth stage on milk production were observed with barley whereas delaying wheat harvest increased milk yield. Different types and levels of concentrate induced mainly similar intake and milk yield responses with diets based on GS alone or on mixtures of GS and WCS. The synergistic effect of mixing GS and WCS was more positive in experiments where the protein concentration of concentrate was high (200 g kg-1 DM).;

Milk Characteristics

Success in making a cheese acceptable in both flavour and texture depends partly on curd properties which determine the retention of fat and moisture and, thus, cheese yield and composition (Green & Grandison, 1993). When considering farmhouse and/or Appelation d'Origine Contrôlée cheese where milk treatments are not allowed, curd properties depend only on milk composition and clotting characteristics, which are subject to wide fluctuations over the year owing to the cow's stage of lactation and nutritional factors (O'Keeffe, 1984; Macheboeuf et al. 1993). These variations often result in seasonal differences in the chemical or sensory properties of the cheese (Kefford et al. 1995) which are sometimes difficult to understand (Grandison et al. 1985). Only a few studies have assessed the cheesemaking quality of milk by actually making ripened cheese; most studies report milk coagulation properties and curd firmness.The object of this work was to study the influence of the chemical composition and clotting characteristics of the milk on the chemical and sensory properties of ripened cheeses when milk characteristics vary widely.

The organization of feeding of highly productive cows is one of the most difficult tasks in dairy cattle breeding. The purpose of the work was to study the influence of natural mineral additive on the productivity, composition and some technological qualities of milk of cows of Black-and-White breed of Ural type. Research and production experiment has been carried out in CJSC “Glinki” in the Ketovsky district in the Kurgan region on Black-and-White cows. The influence of bentonite additive in the ration of highly productive cows during the period of increasing the milk yield on the composition and technological quality of milk and dairy products has been determined. In general, for the first 100 days of lactation the cows of the experimental group have produced by 191 kg more natural fat milk or 8,4 %, compared to the control group. In terms of 4 % milk from animals of the experimental group has been got by 233 kg or 9,3 % more than of the control group. The yield of milk fat in the experimental group was by 10,44 kg or 12,9 % more than the control group. The difference in milk protein yield for 100 days of lactation was 7,34 kg or 9,8 %. The economic indicators (prime-cost, profitability) of milk production when feeding the mineral additive bentonite to cows have been calculated. With an increase in the total cost of obtaining milk from cows of the experimental group, caused by higher milk yields and the purchase of bentonite, the revenue from the sale of milk from this group was by 7,83 thousand rubles or 8,4 % more. As a result, milk production from animals of the experimental group was by 3,44 % more efficient. It has been found that the inclusion of bentonite in the composition of concentrated feed in the amount of 400 g/head/day allowed to reduce their expenditure, as well as EFU and digestible protein, which ultimately provided a higher level of profitability of milk production.

The Relationship

The records of 2400 cows on test at the London Dairy Show between the years 1922 and 1934 have been examined for the relationship between the gross physiological efficiency of milk production and the factors of breed, size of cow within a breed, actual yield of milk and stage of lactation. (“Gross Efficiency” is here the ratio of energy in the milk to the energy in the digestible nutrients consumed.)(1) It is shown that among the best representatives of the various dairy breeds there is little difference in gross efficiency of milk production. The lactation stimulus has been bred approximately in proportion to the size of the breed.(2) Cows, in spite of their greater weight, are more efficient than heifers, and animals milked thrice daily than those milked twice daily.(3) Within the breed there is a slight though definite tendency for gross efficiency to decrease with increase in live weight.(4) Greater than any of the foregoing differences in gross efficiency is that which exists within a breed due to differences in actual milk yield.(5) Stage of lactation has also much to do with gross efficiency. There is a steady decline in efficiency with advance in lactation from 38·75 to 29·25 per cent.

The aim of the study was to determine the influence of the stage of lactation on the yield and quality of sheep milk. The material for the investigation was milk from morning milking of 30 East Friesian sheep in their third to fifth lactation. Milking began after the lambs were weaned and continued for about 120 days. Milk samples were collected individually from the sheep in three stages of lactation: at its peak, during the stabilized stage and at the end (late) lactation. Daily milk yield, total bacterial count, somatic cell count and the basic composition of the milk were determined. The microbiological quality of the milk was very high and the somatic cell count was favourable. As lactation progressed the somatic cell count increased while microbiological quality remained stable. At the end of lactation a significant increase was noted in the concentration of dry matter, protein and fat, accompanied by a decrease in lactose concentration, in comparison with the peak of lactation. Yield was shown to be negatively correlated with fat (–0.63; p≤0.01) and dry matter (–0.53; p≤0.01) and positively correlated with lactose (0.61; p≤0.01).
