“…However, Musa et al (2005) reported 112 days for Sudanese cattle, while Ishag (2000) found that the dry period for crossbred dairy cattle was 90.5 days. It is commonly estimated that a twomonth dry period provides a complete regeneration of udder glandular tissue and is favorable for the high production in the forthcoming lactation (Annen et al, 2004;Andersen et al, 2005).…”

Calving records of Holstein cows from January 1983 to December 2006 comprising 1,190 herds with 384,717 calving events were used to evaluate factors affecting the dry period length and effect of current dry days on the next productive and reproductive performances of Holstein cows. Statistical analyses of dry days, productive and reproductive traits in this study were performed as linear mixed models. Dry period length (DD) of cows was grouped into 14 classes from < 10 days through > 130 days. Average DD was 100.46 days in Holstein cows. Primiparous cows had the lowest DD and the mean of DD decreased over the years from 1983 to 2006 and summer calvers had the shortest DD (p < 0.001). Cows within the DD classes of 51-60 and 61-70 had the greatest actual milk yield, mature equivalent milk yield, adjusted milk yield, adjusted fat yield, mature equivalent milk yield, adjusted protein yield and mature equivalent protein yield (p < 0.05). Also, cows within the DD class of 0-10 had the greatest adjusted fat percentage, mature equivalent fat percentage and adjusted protein percentage (p < 0.05). Our current results showed a reduction in calving interval and age at calving after cows had shorter dry days than with other longer dry period lengths (p < 0.05). Given the recent advocacy for shortened dry periods, it is worthwhile to emphasize that 51 to 70 DD does provide maximal performance in Holstein cows.Additional key words: dairy cow; dry days; productive performance; reproductive performance.

“…Other well-known beef-dairy cattle are Ogaden cattle (Small East African Zebu) ( Rege and Tawah, 1999 ), Jiddu cattle (Zenga) (Box, 1968), and Fogera cattle (Zenga) ( Gebremedhin et al, 2007 ). While the Kenana and Butana cattle from Sudan are amongst the best milk producing zebu breeds ( Musa et al, 2005 ).…”

At least 150 indigenous African cattle breeds have been named, but the majority of African cattle populations remain largely uncharacterized. As cattle breeds and populations in Africa adapted to various local environmental conditions, they acquired unique features. We know now that the history of African cattle was particularly complex and while several of its episodes remain debated, there is no doubt that African cattle population evolved dramatically over time. Today, we find a mosaic of genetically diverse population from the purest Bos taurus to the nearly pure Bos indicus. African cattle are now found all across the continent, with the exception of the Sahara and the river Congo basin. They are found on the rift valley highlands as well as below sea level in the Afar depression. These unique livestock genetic resources are in danger to disappear rapidly following uncontrolled crossbreeding and breed replacements with exotic breeds. Breeding improvement programs of African indigenous livestock remain too few while paradoxically the demand of livestock products is continually increasing. Many African indigenous breeds are endangered now, and their unique adaptive traits may be lost forever. This paper reviews the unique known characteristics of indigenous African cattle populations while describing the opportunities, the necessity and urgency to understand and utilize these resources to respond to the needs of the people of the continent and to the benefit of African farmers.

“…Cattle are the main source of milk and meat in the Sudan and despite the huge numbers of cattle in the country (36 million heads according to AOAD, 2004) the Sudan has to import an appreciable proportion of its milk requirements. Although highly adapted to the local environment and to the needs of stockholders the indigenous types of cattle are mostly poor milk producers, but there are some promising local types (SAEED et al, 1987;MUSA et al, 2005). The need for a quick solution to the problem of the deficit in milk production has led to the importation of high producing European dairy breeds.…”

Abstract. The data obtained from the dairy herd of the Arab Company for Agricultural Production and Processing (ACAPP) in a semi arid area 40 km south of Khartoum involved 337 cows with a total of 1049 records from 16 years between 1986 and 2002. The least squares means for age at first calving, calving interval, days open, lactation milk yield, daily milk yield, lactation length and dry period were 29.76±0.40 months, 433.12 ± 6.70 days, 167.79±7.08 days, 3475.53±78.89 kg, 12.29±0.28 kg, 294.10±3.62 days and 164.08 ± 6.70 days, respectively. The analysis of variance showed that the parity number had significant (p<0.05) influences on all studied traits, while year-season of calving influenced (p<0.05) age at first calving, milk yield per lactation and daily milk yield. The sire of cow influenced (p<0.05) lactation yield, daily yield, lactation length and days open. The effects of linear and quadratic regressions of both lactation yield and daily yield on length of lactation were also highly significant (p<0.01). Heritability estimates of age at first calving, calving interval, milk yield per lactation, daily milk yield, lactation length and dry period were generally low (0.098±0.104, 0.047±0.046, 0.130±0.042, 0.123±0.041, 0.172±0.062 and 0.044±0.031, respectively) except the heritability of days open which was 0.51±0.37. The productivity of the herd in this study which averaged 12.3 kg/cow/day was much lower than the expected productivity of Holstein Friesian cows, which reflects the negative impact of the prevalent environment in the Sudan. More records and economic data are required to examine the economic feasibility of raising pure Friesians under Sudan conditions.
