Milk production in the villages of Mauritius can be characterised as follows: about 90% of the ‘dairy’ cows on the island are owned by villagers. Cattle-rearing is a side-line activity of the family. Most villagers own one cow With a calf. No forage is cultivated. Forage sources for the cattle include sugar cane tops from June to December (harvest season) and shrubs and mixed grasses from road sides and common lands all the year round. All forages are available free and are collected by hand. There is very little or no use of concentrate supplements.The cattle are a mixture of the local Creole breed, Friesians and their crosses. Artificial insemination is widely used. Milk production is generally low (1200-1500 litres per lactation) when compared with European dairy cows. Lactations are normally relatively short (225-250 days) and calving intervals long (15-18 months).Since these cattle contribute more than 90% of the national production of fresh milk it Was decided, within the context of a project financed by the United Nations Development Programme, to investigate the extent to Which their productivity could be improved.

Pre-1990 published responses to supplementation at pasture ranged from 0.4 to 0.6kg milk/kg concentrate fed. However since 1990 higher responses to concentrate supplementation at pasture have been published (Delaby 2001). The objective of this study was to determine if milk production responses of Holstein-Friesian dairy cows to concentrate supplementation at pasture are influenced by genetic merit (milk yield potential) in a spring calving grass based system of milk production.

Concentrates are the main cash expenditure in smallholder campesino dairying in the highlands of Central Mexico. Improved, low-cost, appropriate feeding strategies have been therefore identified by campesinos as a priority. An on-farm trial was undertaken in 1998 to evaluate the response to supplementation with concentrates by dairy cows in early lactation during the rainy season with restricted access to grazing of ryegrass/white clover pastures. A base of 3·0 kg commercial concentrate/cow/day (S3) was compared against the higher rate used by farmers of 5·0 kg/cow/day (S5). Three farmers with one, and one farmer with two pairs of freshly calved upgraded Holstein cows participated in the trial (24±10·7 days into lactation). Data were analysed by a random block split-plot design where supplementation treatments were main plots and measurement periods were split-plots. Milk yield was recorded once per week for 9 weeks, and live weight and condition score for four 28 day periods. Milk yields were 21·8 for S3 and 21·9 for S5 (±0·714) kg milk/day/cow (P > 0·05); live weight S3 = 444·0 and S5 = 496·0 (±12·663) kg/cow (P > 0·05), and condition score S3 = 1·9, and S5 = 1·8 (±1·127) (P >0·05). There were no significant (P> 0·05) effects of measurement periods, and there was no significant (P > 0·05) interaction. The lack of response in milk yield, live weight or condition score to increased concentrate supplementation demonstrates that at these levels of production and management, the access to grazing of improved pastures, plus limited concentrate, enables cows in campesino systems to meet their nutrient requirements, and the feasibility of efficient milk production from grazed pastures as an appropriate technology. It is also concluded that it is an appropriate technology and that the results have implications for research and extension workers in rural development who have promoted large amounts of concentrate to dairy cows as the only way towards high yields and efficient milk production.

Two Factors

The efficient use of forages for milk production by dairy goats requires reliable estimates of the responses in intake and milk production to concentrate supplementation. Based on the results of experiments with dairy cows, two factors of particular importance are likely to be amount of concentrates and quality of the protein.

The effects of concentrate supplementation of timothy hay cut at the late-boot and early-bloom was tested with dairy cows during two feeding and two digestibility trials. The diets for each trial contained the following hay to concentrate ratios: 100:0, 85:15, 70:30 and 55:45. Daily dry matter intake and fat-corrected milk production, respectively, were 15.1, 16.8, 18.6, 19.4 kg; 16.7, 20.7, 23.1, 21.0 kg for the four diets containing early-cut timothy hay and 11.0, 14.7, 17.2, 19.8 kg; 8.4, 10.7, 13.3 and 15.9 kg for the late-cut timothy hay. Percent digestibilities of the four diets containing early-cut and late-cut timothy hay, respectively, were 65.6, 65.6, 66.9, 66.8 and 53.6, 53.6, 60.2, 62.9 for dry matter; 62.5, 63.7, 65.2, 65.3 and 24.0, 39.3, 53.3, 60.0 for nitrogen; 70.3, 70.3, 68.4, 67.8 and 53.7, 53.4, 60.1, 62.6 for gross energy; 66.4, 65.3, 67.1, 66.6 and 55.0, 54.5, 61.4, 63.5 for cell wall constituents; 68.2, 65.8, 64.9, 63.4 and 50.8, 48.2, 52.7, 52.1 for acid detergent fiber. Timothy hay cut at late-boot stage as sole source of feed supported a daily milk production of 16.7 kg compared to 15.9 kg for cows consuming timothy hay cut at late-bloom stage supplemented with 9 kg of concentrate.
