Comparison Impact of Milk Yield on Economics and Profitable of Different Dairy Cattle Herds of Governmental and Private Sectors in Egypt

Abstract

The data was obtained from three commercial dairy herds. The Holstein Friesian cattle in San-Elhagar station of El-sharqia and second flock Michelle station in Dakahlia, German in the Compra station of Giza for Friesian cows and the third flock of the Baron Suisse at the station of Compra Giza. The fourth flock is a government herd in two herds (Sakha and El-Karada) for comparison of profitability of four flocks. Technical coefficient of productive traits, milk yield per day (MY/D), Initial milk yield (IMY), 305-day milk yield (dMY), Total milk yield (TMY), lactation length (LL) and dry period (DP) and Number of Complete seasons for milk Yield (NCSM) and reproductive traits age at first calving (AFC), number of services per fertilization (NSPF), Days Open (DO) and Calving interval (CI) were calculated. Average milk yield was 6780, 4185kg, 4223 and 2875kg/lactation, respectively for (H1, H2, H3and H4). (H1) increased by 2.6%, 2.6% and 3.9% times more than H2, H3, and H4 for total milk yield with the least standard deviation of the fourth herd (SD= 448.7Kg). Effects of all factors (month, year and herd) on all traits studied were highly significant (P<0.01) excluding effect of month and year of calving on (NSPF) that were not-significant. The herd high milk yield (H1) has a poorer reproductive performance with the least parity for each cow than that of H2, H3 and H4 were, respectively. Annual variable cost per cow of H1 is higher than the other three herds which is attributed mainly to feeding and this is the main cause of the variable cost and the Interest/cost ratio of H1 was 1.51 relative to 1.33, 1.31 and 1.34 for H1, H2, H3, and H4, respectively. While, the total gross output of for the whole lifetime production of H3, exceeded those of H1, H2, and H4 by 5.39%, 22.29%, and 10.97%, respectively. Moreover, the profit per cow during the lifetime of high milk yield herds H1 is higher than that of H2 by about 56.83%, higher than H3 by about 34.97% and higher than H4 by about 40.72%. at last, high milk producer cows. With a perfect period for calving interval and days open but shorter dry period and longer lactation length on the intensive farming system more gainful than those have shorter and longer calving interval and days open on semi-intensive farming system.
