A field study was conducted in Ghaziabad District to observe the effect of mineral mixture feeding on milk yield in Buffalo. Animals were selected randomly from 5 villages of Ghaziabad, Uttar Pradesh viz. Muradnagar, Noorpur, Kanoja, Kusalia, and Badka. 20 Buffaloes were selected in their 2nd and 3rd stage of lactation and divided into two groups of 10 animals each. First group (T) was fed with 60 gm mineral mixture daily till 90 days of lactation. Other groups (C) of 10 animals were not fed additional mineral mixture, which is farmers practice in that particular area. The farmers were not fed scientific method of feeding. They could not added proper quantity of mineral mixture in balance ration. To keeping in mind a trial was conducted in Ghaziabad District since 2016-17 to 2017-18. Milk yield of these animals was recorded by their owners and these values were averaged for fortnightly interval. Milk production parameters like average daily milk yield, peak yield and total milk yield were compared between treatment and control groups. It was observed that average daily milk yield, peak yield and total milk yield were found significantly (P less than 0.05) higher by 11.04, 12.37 and 11.61% in mineral mixture fed group than control group. On the basis of this, it is recommended that continuous feeding of mineral mixture bettered performance of milk yield in buffaloes.

SummaryTwo experiments are described in which spring-calved Ayrshire cows were fed supplementary food when grazing good, leafy pasture.In the first experiment 6 lb of a mixture of three parts bruised oats and one part flaked maize was fed daily to three groups of five cows. One group received the supplement from 1 July until 30 October, and the other two groups from 1 August and 1 September respectively. A control group received no supplement.In no month was there any statistical difference in daily milk yield between supplemented and unsupplemented groups of cows. The group fed from 1 July gave the highest total milk yield in the period June to October, but with a return of only 1 gal of milk from 34 lb of meal.The length of the lactation was not significantly affected by the treatment.In the second experiment, three groups of four cows on a 9-week change-over trial (4 May-5 July) grazed herbage containing an average of only 17·6% dry matter and 3·8% crude fibre. On the three treatments the cows ate pasture only, pasture plus 1·6 lb hay/day and pasture plus 5·7 lb of meal/day. The meal consisted of four parts by weight of undecorticated cotton cake, four of bruised oats and three of locust beans.Milk yield was significantly increased from 41·8 lb on the all-grass ration to 43·2 lb/day on the meal treatment but the hay did not affect milk yield.The fat content of the milk was significantly increased from 3·77 to 3·91% on the hay treatment, whereas the solids-not-fat content of the milk was not significantly affected by any of the treatments.At the present-day prices of the feeds and with cows on good leafy pasture it was clearly uneconomic to feed the meal supplements.

In order to effectively provide the body of cows with energy during the increasing the milk yield without the risk of acidosis, progressive animal breeders of the Altai Territory include wet flattened corn grain in the composition of concentrated feed. The question of the expediency and economic effectiveness of using wet flattened corn grain for cows of various physiological groups – first-calf heifers and mature animals continues to be debatable. Therefore, a comparative assessment of two options for feeding wet flattened corn grain to cows under the conditions of the Altai Territory is considered promising in modern animal husbandry and is of great practical interest. The purpose of the work was to identify the optimal and economically feasible option for using wet flattened corn grain in the rations of lactating cows. When using wet flattened corn grains in an amount of 7,1 % of the nutritional value of the ration the first-calf heifers during the period of increasing the milk yield, productivity has increased by 20,9 %. The average daily milk yield was 17,3 kg, which significantly exceeded the indicator of the control group (P > 0,95). The inclusion of wet flattened corn grains in the ration of mature cows in the amount of 1 kg for 30–35 days before calving, then 4,5 kg from 15 to 75 days after calving allows us to get the average daily milk yield of 30 kg or 20,3 % higher than that of the control group of herdmates (P > 0,95). The effectiveness of the use of wet flattened corn grain had significant indicators: the total profit from the sale of dairy products of the first-calf heifers of the experimental group amounted to 16 251,3 rubles/head, and from the sale of milk of mature cows of the experimental group it was 30 346,43 rubles/head.

Изучены функциональные свойства вымени коров голштинской породы австралийской селекции, выращенных с использованием повышенных норм выпойки молока и добавлением пробиотического препарата целлобактерин . В сельхозпредприятии Краснодарского края, на потомках импортного скота голштинской породы австралийской селекции, завезенного в 2008 году. Для проведения опыта от нетелей линии Рефлекшн Соверинг 198998 получили телят и сформировали 4 группы подопытных телочек по 16 голов (n64): I контрольная, II, III, IV опытные. Животные были аналогами по происхождению, живой массе и возрасту. Различие между группами заключалось в технологии их выращивания. Телки контрольной группы выращивались по технологии принятой в хозяйстве, а животных II, III и IV опытных групп кормили опытными рационами. В состав кормовых рационов телочек опытных групп входило неодинаковое количество кормов животного происхождения и пробиотический препарат. После отела было установлено, что коровы опытных групп превосходили сверстниц I контрольной группы по обхвату вымени на 0,83,0 см. По 3 лактации различия по изучаемым промерам подопытных групп составили 1,33,5 см. При изучении промеров глубины вымени по 1 и 3 лактации установлена такая же закономерность по их увеличению, как и по обхвату вымени. Наиболее высокие суточные удои установлены у коров III группы 26,2 кг, превосходство над сверстницами контрольной группы по этому показателю составило 4,3 кг, или 19,6. По скорости молокоотдачи животные контрольной группы уступали сверстницам опытных групп. Индекс вымени во всех группах был достаточно высоким, и составлял по 1й лактации 44,846,2, по 3й 45,347,4. Суточные удои коров по 3 лактации возросли. Доказана зависимость между величиной вымени и удоем за лактацию. Интенсивное выращивание подопытных телок с добавлением пробиотического препарата положительно отразилось на увеличении у них промеров вымени, когда они стали коровами, что способствовало повышению удоев с 1по 3 лактации. Установлено, что коровы опытных групп по 1 лактации превышали сверстниц контрольной на 1,44,3 кг. По 3 лактации превышение составило 1,45,4 кг. Установлено, что коровы опытных групп превосходили сверстниц I контрольной группы по функциональным свойствам вымени.Functional properties of udders of Holstein cow breed of Australian selection grown with the use of increased norms of milk feeding and the addition of Cellobacterine probiotic preparation were studied. Research was carried out on the basis of agricultural enterprise located on the territory of Krasnodar region using the offspring of Hostein cow breed of Australian selection imported in 2008. 4 groups of test cow calves consisting of 16 animals (n64) received from Reflection Sovereign bred heifers 198998 were formed to carry out the experiment. There was group I which was used as control, and groups II, III, and IV which were used as test groups. Animals had similar origin, live weight and age. The groups were differentiated by growth technology. Cow calves from the control group were grown according to the traditional technology, and animals from group II, III, and IV received experimental feed. Nonuniform quantity of feeds of animal origin and probiotic preparation were included in feed rations of cow calves from test groups. After calving it was found that test cows were superior to animals from control group I in udder circumference by 0.83.0 cm. During the third lactation period the differences according to the studied measurements of test groups amounted to 1.3 3.5 cm. Analysis of udder depth measurements during the first and the third lactation period showed the same tendency towards increasing as during the analysis of udder circumference. The highest daily milk yield was registered in the cows from group III 26.2kg, the superiority to the cows from the control group in this parameter amounted to 4.3 kg or 19.6. Milk flow speed of control group animals was inferior to that of the cows from test groups. Udder index was rather high in all of the groups and during the first lactation period amounted to 44.846.2, the third 45.3.47.4. Daily milk yield increased during the third lactation period. The dependence of the size of the udder on milk yield per lactation was proved. Intensive growth of test cow calves with the addition of probiotic preparation positively influenced the increase in udder measurements when they became grown cows, which facilitated the increase in milk yield from the first to the third lactation period. It was found during the first lactation period test group cows were superior to the cows from the control group by 1.4 4.3 kg. The increase amounted to 1.4 5.4 kg during the third lactation period. It was also found that test group cows were superior to the cows from the control group in terms of udder functional properties.

The aim of this study was to analyze effect of genetic and environmental factors on milk production traits of indigenous Balkan goat breed. The average milk yield of 150.43 kg in lactation that lasted 211.09 days was significantly influenced by flock and lactation, while average daily milk yield (0.724 kg) was additional significantly affected by stage of lactation (PÂ0.001). Variability of milk components content (fat, protein and solid nonfat – SNF) was under significant effect of flock and stage of lactation, interaction of these two factors and random effect of animal (PÂ0.001), while strain and lactation did not have significant effect on these traits (P>0.05). Goats of AA genotype of alpha S1 casein had significantly higher fat, protein and SNF content than AF and FF genotype. These results provide important data that could be used as baseline for design of breeding program for improvement of production traits of Balkan goat breed.

The lasalocid supplement, Bovatec, was fed to dairy cows at 300 mg of active ingredient for ~3 weeks precalving to up to 16 weeks postcalving in a pasture-based system. Sixty primiparous cows and 120 multiparous cows were allocated to equivalent control and lasalocid groups based on expected calving date, size and previous production history. To facilitate the feeding of the lasalocid, it was mixed with maize silage (~1 kg DM/cow.day) and fed as one feed on a concrete feed pad early in the morning each day before calving and before the afternoon milking during lactation. The control group received the maize silage without lasalocid. Otherwise, the feeding of both groups was exactly the same. The key response associated with adding lasalocid to the diet differed between the primiparous and multiparous cows. Although the average daily milk yield responses to lasalocid were not significant (P > 0.05) at 1.1 and 0.6 kg/cow for the primiparous and multiparous cows, respectively, significant (P < 0.05) increases in the milk yield of the primiparous cows were consistently recorded between weeks 5 and 15 of lactation. With the multiparous cows, there was a significant (P < 0.05) decrease in the circulating concentrations of serum β-hydroxybutyrate in those fed the lasalocid, with this being related to a tendency (P = 0.087) for these animals to maintain higher body condition scores for much of the early lactation treatment period. There were no other treatment differences of biological importance.

Thirty-four procedures were used to estimate the weekly yields of milk, milk fat and milk protein of 19 grazing cows on five occasions between the third and eighth months of lactation. The standard deviation of daily milk yield, fat and protein percentage of individual cows averaged 1 .3 litres, 0.58% fat and 0 - 10% protein, respectively. The four factors involved were: sampling frequency, sampling distribution, basis of compositing subsamples for compositional analyses, and the use of total weekly yields or milk yields on day(s) of sampling, for estimating yields of fat and protein. There were no substantial interactions between the 34 procedures and stage of lactation. The average difference between the estimate of weekly milk yield from any one day's yield and the true weekly milk yield (accuracy) was 7.2 litres/week. The equivalent values for fat and protein yields were 0.59 and 0.22 kg/week. When sampling frequency and measurement of milk yield was increased from one to six days per week, the accuracy of the weekly estimate of milk yield (MY) improved by 5.7 litres/week and that of fat yield (FY) by 0.49 kg/week. If total weekly milk yield was used to estimate fat yield, instead of using milk yield on days of testing only, the improvement in accuracy ranged from 0. 15 to 0.03 kg/week for one and six samplings, respectively. Two equally spaced sampling days gave a marginally better (0.74 litres/week) estimate of milk yield than two consecutive days but a marginally poorer (0.10 kg/week) estimate of fat yield. Yield weighting of subsamples for fat or protein analyses did not improve the estimate of fat yield. As the day to day variation in level of protein in the milk was low, frequency and method of sampling for protein analysis was not important but the accuracy of estimating milk yield had a large effect on estimated weekly protein yield.

SummaryDuring the period 1962–73, the majority of the 92 lactations of imported British Friesian animals were initiated during the dry season (October–March). The following average values were obtained: lifetime number of lactations, 4·5; lifetime milk production, 9392 kg; age at producing first live calf, 39·6 months; milk yield of nine lactations, 2159 kg; lactation length, 336·5 days; daily milk yield, 6·3 kg; 305-day milk yield, 2012 kg; dry period, 173 days.Milk production was highest in the fourth lactation when the animals averaged 7 years old. Differences in milk yield among lactations were small. Peak daily milk yield was greatest in the third lactation and was reached within the first 21 days of each of the first four lactations. A second but lower peak with the highest milk production persistencies at a later stage of lactation apparently depended on feed availability. The 305-day milk yield was reasonably predicted from the 100- and 200-day yields.Lactations subsequent to abortions and stillbirths were slightly longer, gave less milk (P > 0·05) and were followed by longer dry periods than those initiated by normal births.

A total of 54 samples were collected from 18 milking cows from which nine were indigenous and nine were crossbred to evaluate the effects of different lactation number and different stage of lactation on the milk yield. The average daily milk yield of indigenous and crossbred cows at 1st, 2nd and 3rd lactation were 1.311, 1.633, 2.072 and 8.917, 9.567, 10.167 liter/day/cow respectively and represented the significant difference (p<0.01) within the daily milk yield of different lactations. Milk yield increased gradually from 1st to 3rd lactation. The highest milk yield was recorded in 3rd lactation and lowest was in 1st. The mean milk yield of indigenous and crossbred cows at early, middle & later stages of lactations were 1.617, 2.094, 1.306 and 9.389, 10.222, 9.039 liter/cow/day respectively that revealed stages of lactation had significant effect (p<0.01) on milk yield per day. It was observed that milk yield decreased after 2nd stage of lactation and decreased linearly up to the end of lactation. The highest milk yield was recorded in 2nd stage of lactation and lowest was in 3rd stage of lactation. The overall milk production in different lactation for indigenous cows was 1.672 liter/day and for crossbred cows was 9.550 liter/day that may be concluded as crossbred cows are superior to indigenous in concern of milk yield.Keywords: Indigenous cows; crossbred cows; lactation number; stage of lactation; milk yield.DOI: http://dx.doi.org/10.3329/ijns.v1i1.8614 International Journal of Natural Sciences (2011), 1(1):31-34

ABSTRACTMean daily milk yield, fat concentration and protein concentration in the milk of 579 303 British Friesian, 6 608 Shorthorn, 27 374 Ayrshire, 19 529 Jersey and 19 760 Guernsey cattle were recorded monthly from August 1978 to July 1979 inclusive, and classified by breed, parity, stage of lactation, and five geographical areas according to the location of the herd. Parameters of the function Y(n) = anbecn were estimated for each breed/parity/area group for yield, fat concentration and protein concentration (b and c describe the shape of the curve, a is a scalar, n the week of lactation and e the base of natural logarithms). Systematic deviations from the function were associated with the season of production, reflecting the spring and summer flush of milk yield. Fat and protein concentrations also exhibited seasonal variations from the underlying curve. After correction for the seasonal fluctuation in production, there was no variation in total yield, fat concentration or protein concentration associated with the month of calving.

AbstractThe objective of this work was to investigate phenotypic sources of variation in the sites of storage of milk within the udder. Ten primiparous and 10 multiparous dairy cows were studied over two successive lactations in order to investigate the effects of age, parity and stage of lactation. Cistern and alveolar milk volumes were estimated at a standard 8 h after a normal morning milking by catheter drainage and machine milking with oxytocin respectively. Measurements were made at approximately 9, 20, 30 and 42 weeks of the initial lactation and weeks 1, 4, 7, 10, 20 and 34 of the subsequent lactation. In the initial lactation, there was a significant difference between primiparous and multiparous animals in the rate of decline of total daily milk yield (P&lt; 0·001). Cistern milk yield (kg/8 h) from multiparous animals declined over the lactation whilst that for primiparous animals was maintained. The effect was shown as a significant interaction effect (P&lt; 0·05). For both multiparous and primiparous animals cistern proportion (cistern yield divided by total milk yield at 8h after a normal milking), increased over the lactation (P&lt; 0·001). This was largely a consequence of the reduced total milk yield. Eleven animals were studied through the subsequent lactation. Cistern yield followed a lactation curve of similar form to that for total yield. The decline in cistern yield over this lactation was much greater than the decline with multiparous animals in the previous year. This may, in part, reflect a faster decline in total daily yield. Stage of lactation and parity must be taken into account if a standardized evaluation of cistern characteristics is to be obtained.
