The productive performance of Red Kandhari cattle were studied at different locations in the breeding tract. The idea behind the collection of data in breeding tract of Red Kandhari cattle from the farmers and breeders herd of Red Kandhari rather than on the organized farm to obtain the real picture of productive performance of breed in the breeding tract. The productive traits often help in judging the economic value of the animal. The overall least square means for lactation milk yield (LMY) of Red Kandhari cattle was recorded as 417.28 + 1.09 kg. The effect of block and season were found significant to highly significant on LMY whereas, the effect of colour was found non-significant. The overall least square means for peak milk yield (PMY) of Red Kandhari cattle was recorded as 2.63 + 0.01 kg. The effect of block, colour and season were found non-significant on PMY. The overall least square means for days to reach peak milk yield (DRPMY) of Red Kandhari cattle was recorded as 39.48 + 0.09 days. The effect of block, colour and season were found non-significant on DRPMY. The overall least square means for lactation period (LP) of Red Kandhari cattle was recorded as 242.64 + 0.46 days. The effect of block was found highly significant on LP whereas, the effect of colour and season were found non-significant. The overall least square means for dry period (DP) of Red Kandhari cattle was recorded as 180.79 + 0.56 days. The effect of block and colour were found non-significant on DP whereas, the effect of season was found significant. The improvement in productive characteristics of indigenous breeds has become essential to make the economically viable dairy animals.

The study was conducted to understand the effect of season, parity and stage of lactation on productive performance of Sahiwal cattle. The data of productive traits of 133 Sahiwal cattle from 2016 to 2018 maintained at the Livestock Research Center, Karnal, Haryana, were used for this study. The production data were analyzed using least-square procedures based on season, parity and stage of lactation. Results indicated that the parity had significant (p less than 0.05) influence on monthly milk yield (MMY) whereas, the stage of lactation had highly significant (P less than 0.01) influence on monthly milk yield (MMY) and test day milk yield (TDMY). However, there was no significant effect of season on different productive performance traits in Sahiwal cattle. The phenotypic parameter estimates indicated that the parity and stage of lactation of cattle can be used as a selection tool for improvement of productive traits considering its high positive phenotypic correlations with succeeding productive traits in Sahiwal cows.

Dairy Animals

The rate of milk secretion in dairy animals displays a trend throughout the lactation period. It increases to a maximum in a few weeks following parturition and decreases thereafter until the animal goes dry.This trend draws a certain curve, namely the lactation curve.The milk yield of a single lactation may be influenced by many factors but the general shape of the lactation curve defined by the locus of weekly yields remains substantially unchanged. It rises rapidly to the peak within a few weeks after calving followed by a more or less gradual decline until the end of lactation.The analysis of the lactation curve, i.e. the week to week output of milk and trend of increase and decrease in yield with advancement of lactation is important for day to day management and forward planning of dairy herds by reliable forecasting of week by week milk production, seasonal variation and the total milk yield of individual cows or groups of cows.A number of reports pertaining to dairy cattle have been published but very few studies have been concerned with buffaloes. In most of the countries, the buffaloes have been used for draught purpose but it is in the Indian subcontinent that this animal is seen at its greatest advantage as a source of animal protein, i.e. milk and meat for human consumption.

Often the only way to ensure profitability of Lacaune dairy sheep is intensive management, which requires appropriate dry-period treatment to ensure animal productivity and health. The present study aimed to investigate the effects of intramammary antibiotic dry therapy on the performance and health of Lacaune sheep under intensive management. We recorded data for 5981 complete lactation periods that followed a dry period. A total of 2402 lactation periods were preceded by a dry period involving intramammary administration of 300 mg of cephapirin benzathine (antibiotic group) and 3579 lactation periods were preceded by dry periods with no treatment (control group). The following on-farm yield data were collected for individual lactation periods: length of the subsequent lactation period; total milk yield per lactation period; daily milk yield and length of the subsequent dry period. Data on confounding factors that might affect productivity were also recorded, including the individual ewe, number of lactation periods and length of the previous dry period. Milk quality was assessed using data on somatic cell count (SCC) and content of protein and fat taken from the Spanish National Official Milk Yield Recording System. Antibiotic dry therapy significantly improved total yield per lactation period, which was 429±151·1 l in the antibiotic group and 412±165·5 l in the control group, as well as the daily milk yield, which was 1986±497·0 and 1851±543·2 ml/d, respectively (both P<0·0001). The initial dry period was significantly longer in the antibiotic group than in the control group, and dry period length correlated inversely with yield variables such us total yield per lactation period (r=−0·055; P<0·0001) and yield per day in milk (r=−0·039; P<0·0001). As a result, milk yield records systematically underestimated the positive effects of antibiotic dry therapy. Antibiotic dry therapy also significantly improved milk quality. Milk from the antibiotic group showed 50% lower SCC (573±1326 vs. 1022±2126 cells/ml; P<0·0001) and slightly higher content in fat (7·33±0·91 vs. 7·15±0·87%) and protein (5·63±0·44 vs. 5·44±0·4%). The results of this study suggest that cephalosporin dry therapy of Lacaune dairy sheep increases milk production and improves milk quality during subsequent lactation periods.

Abstract The aim of this study is to estimate the genetic parameters and the effect of non-genetic factors for some milk traits including total milk yield (TMY/kg), Lactation period (LP/day), number of services per conception (NSC), days open (DO), calving interval (CI) and dry period (DP). Data were collected from two farms. Experimental Farm belonging to (APRI) data included 1829 records. The statistical analysis has been adopted using animal models. Actual means of TMY/kg, LP/day, NSC/services, DO/day, CI/day and DP/day were 791.3, 171.1, 1.8, 109, 402.7 and 79.3 respectively. Estimated heritability (h2) of TMY, LP, NSC, DO, CI, and DP were 0.18± 0.01, 0.18± 0.001, 0.07± 0.016, 0.09± 0.041 and 0.09±0.001 respectively. The ranges of breeding values BV of cows for TMY/kg, LP/day, NSC, /services, DO/day, CI/day and DP/day were 776.5, 26.7, 6.7, 13.4, 77.1 and 11.5 respectively. The estimated Predicted Breeding Value PBV for all traits varied widely. The genetic trends of cow breeding values were significant for all studied traits. This confirms that the genetic improvement of these traits leads to increased milk production traits. The study recommends preserving the Native Egyptian dairy cattle because they represent a national wealth that must be preserved from extinction through inventorying the genetic resources, characterization and evaluation of this local breed to benefit from it in improving animal breeds of high economic value. Due to the distinction of Egyptian domestic cows for their resistance to various environmental conditions.

The data on 481 lactation records including 204 records of Red Kandhari cows and 277 records of Jersey x Red Kandhari crossbred cows were collected from Cattle Unit, College of Veterinary and Animal Sciences, (MAFSU), Parbhani over a period of 27 years (1977-2004). The lactation milk yield for first, second, third, fourth and fifth and above lactations for Red Kandhari cows were 375.16±34.15 kg, 458.17±37.62 kg, 450.91±26.74 kg, 532.69±67.74 kg and 674.29±82.09 kg, respectively and for Jersey x Red Kandhari crossbred were 1100.28±73.18 Kg, 1318.50±135.20 Kg and 1353.92±91.61 Kg, 1549.77±188.47 kg and 1438.37±48.89 kg, respectively. The first lactation length and first dry period in Red Kandhari cows were 273.30±10.33 days and 239.05±21.88 days, while in Jersey x Red Kandhari crossbred cows were 302.68±9.19 days and 86.72±8.90 days, respectively. The least square analysis of variance for first, second and third and more than three lactations for lactation milk yield, lactation length and dry period showed that the genetic group had significant source of variation for all traits in all lactations except first and second lactation length. Sire within genetic group had significant source of variation for first lactation milk yield and all traits of third and more than three lactations. Season and period of calving had non-significant influence on all the traits in all lactations except first dry period. It was also observed that the improved performance in all the traits under study in Red Kandhari cow and Jersey x Red Kandhari crossbred cow was observed in fourth and fifth and above lactations.
