Milk production potential and reproductive performance of Egyptian buffalo cows

SUMARYThis paper describes the Malvi camel, a very distinctive breed from northern Madhya Pradesh (India), which is characterized by considerable milk production potential. Although the Malvi camel has long been recognized as a distinct population by local camel breeders, scientists were previously not aware of the existence of this breed. Information about the distribution area, estimated population size, and physical characteristics of the Malvi camel is provided and the prevailing management and production system is described. It is concluded that the Malvi camel represents a valuable genetic resource and that steps are necessary to ensure its survival as a separate gene-pool. The way in which this breed was discovered also demonstrates the need for utilizing local indigenous knowledge in the identification and documentation process of animal genetic resources.

ABSTRACTThe level of body reserves in first-litter sows was manipulated by giving gilts one of three levels (high (H), medium (M) or low (L)) of food from selection (44 kg live weight) to parturition. The aim of this experiment was either to maintain or to mobilize these reserves during lactation (31·4 days) by feeding sows to appetite (high (H)) or 2·0 kg/day (low (L)).When the level of body reserves was increased prior to farrowing (171 kg live weight, 32 mm backfat) sows had a lower voluntary food intake during lactation than those animals that farrowed with a low level of body reserves (126 kg live weight, 20 mm backfat) (H-H v. L-H, 3·4 v. 4·9 kg/day; P < 0·001). Both groups had a normal return to oestrous activity after weaning (mean interval between weaning and mating of 14 days) but the heavier animals mobilized more of their body reserves (H-H −30·7 kg live weight, -4·3 mm backfat; L-H -3·6 kg live weight +0·9 mm backfat; P < 0·001). When food intake during lactation was restricted to 2·0 kg/day the interval between weaning and mating was increased by 50% regardless of the level of body reserves present at farrowing. For the same animals, there were insufficient body reserves to support milk production at the same level as for those animals given food t o appetite.

The present study attempts to examine the scenario of buffalo production in Bangladesh. The buffalo plays a very important role in the South Asian region which constitutes 77.5% of world buffalo population. This region has a great biodiversity in buffalo germplasm, including the world famous source promising buffaloes Murrah and Nili-Ravi - renowned for high milk production potential. It is estimated that about 96.05 % of Asia and 93.19 % of world buffalo milk are produced in South Asian countries. Besides, buffalo milk in South Asian countries is around 54.95 % of the total milk production. The India and Pakistan share 67.99% and 23.96%, of world buffalo milk production respectively. About 71.4% of world buffalo meat is produced in South Asian countries. Although buffalo is an integral part of livestock production system in South Asian countries, it has never been addressed in Bangladesh and always neglected despite their important role in the national economy. In Bangladesh, the total buffalo population are 1.464 million heads that are managed in household subsistence farming as well as extensive free range (Bathan) farming in saline coastal region that are used as a draught animal and partially for milk and meat production. The contribution of buffalo in total milk and meat production in Bangladesh is only 2.0% and 0.94%, respectively. This review has tried to unearth the present scenario of buffalo production in Bangladesh, describing the benefits and values of buffalo milk and meat, advantages of buffalo husbandry over cattle, constraints in buffalo production and recommendations for buffalo development in Bangladesh.SAARC J.

The relationship between mean skin thickness or hair follicle depth of the skin from the midside (12th rib) area and milk production levels of pure Friesian (Holstein)cattle breeds, their ¾ and 7/8 crosses with White Fulani zebu, and pure White Fulanis, maintained in South-Western Nigeria were studied. A strongly positive linear correlation (r = 0.9), significant at 1% level was found between skin thickness and hair follicle depth, and milk production levels in these breeds. The results indicate that for cows maintained in a hot humid tropical environment, comparative midside skin thickness and hair follicle depth could be used as indices of the milk production potential of cows. It could be a useful field tool for selection of cows for milk production when considered along with other characteristics

SUMMARYBlood samples were taken from 428 Friesian (Holstein) bulls on three occasions, on average at approximately 3-monthly intervals, between 3 and 15 months of age, and also from 214 of them on three occasions at 6-monthly intervals when they were between 2 and 6 years of age.The average concentrations of blood glucose and haemoglobin and of serum cholesterol, urea, albumin, globulin, inorganic phosphate, Ca, Mg, Na, K and Cu were calculated for each of these periods and correlated with improved contemporary comparisons of milk yield and quality.Repeatability estimates were similar within each of the two periods but were lower when mean concentrations calculated between 3 and 15 months of age were compared with those between 2 and 6 years. The main exceptions were cholesterol (0·52) and Cu (0·54) for which repeatability estimates were similar to those derived within the above two periods. The constituents with the next highest levels of repeatability were magnesium (0·44), globulin (0·43) and inorganic phosphate (0·39), which were approximately 30% lower than those obtained within the two periods.Correlations between blood concentrations and improved contemporary comparisons were negligible, indicating that it is not possible to use these blood constituents to predict the milk production potential of a bull's daughters.
