Reproductive Cycles

Zambian small-holders are dependent on natural grazing to supply the nutrient requirements of their cattle. During the dry season grazing is severely limited, production declines steeply, reproductive cycles become dormant and new-born calves are subject to a high mortality rate. A potential supplemental feed, maize stover, is poorly exploited resulting in extensive field losses. Collection and controlled feeding would greatly increase its efficiency of use, plus such a feed system offers the opportunity to chemically treat the maize stover pre-feeding. This study was conducted to identify the degree to which the nutritive value of this material could be improved using such techniques.

Metabolisable Energy

Approximately 80% of all production costs are related to the purchase of forages and other feeds in dairy enterprises in Mexico. Resource poor, smallholder (campesino) systems are heavily reliant on the use of maize stover, noncultivated/cultivated grass species and weeds to feed their dairy cattle, thus a nutritional understanding of local forage resources would be of considerable economic benefit. The objective of this study was to determine the nutritive value of non-cultivated pastures (NcP) across the growing season.

SUMMARYCereal residues are an important feed source for ruminants in smallholder crop-livestock systems in the (sub)tropics. In many areas of India maize is a relatively new cash crop where farmers and development agents alike generally perceive maize stover to have limited utility, in contrast with the intensive feeding of other cereal residues in India and the intensive use of maize stover in sub-Saharan Africa and Latin America. A comparative assessment of maize stover quality (based on a brief review and a feeding trial) indeed confirms its potential as a ruminant feed according to its relative nutritive value. The paper then explores the apparent paradox through a scoping study of maize stover use (based on village surveys) in three contrasting maize-growing districts in India – including both traditional and non-traditional maize producers. The limited maize stover use appears to alleviate seasonal shortages, with tradition and technology helping explain the preferential use of other cereal residues. The paper thereby provides further impetus to India's apparent food-feed paradigm – whereby farmers’ staple food preferences coincide with crop residue feed preferences. The paper argues the case for investing in maize stover R&D in India and thus reigniting earlier feed research in general. Indeed, maize stover use is a relatively neglected area by India's agricultural R&D and merits more attention so as to exploit its potential contribution and alleviate eventual tradeoffs.

Growth Trial

ABSTRACTForty Menz rams weighing 20 to 22 kg and aged 13 to 18 months were individually offered 1·0 kg/day chopped maize stover and one of five supplements over a 70-day growth trial followed by a 10-day metabolism trial. The amounts of supplement offered were designed to supply 4·4 g nitrogen per day and with stover, sufficient nutrients to allow growth rates of 50 g/day. The control supplement, 80 g dry matter (DM) per day extracted noug (Guizotia abyssinica) meal, was compared with 194 to 212 g DM per day of fruits (pods (carpels) with seeds) of Acacia tortilis, A. albida, A. nilotica and A. sieberiana. For the control and four Acacia supplements respectively, mean growth rates were 32, 32, 21, 16, 4 (s.e.6) g/day and mean stover intakes 483, 430, 401, 347, 320 (s.e. 74) g DM per day. The low growth rates and intakes with A. sieberiana and to a lesser extent A. nilotica were probably related to their content of phenolic compounds including insoluble proanthocyanidins which may have lowered the digestibility of neutral-detergent fibre and nitrogen. A. tortilis and A. albida would appear to be of comparable nutritive value to noug meal as supplements to maize stover. Unlike noug meal Acacia fruits are widely available in rural areas of Africa. Further research is required to identify other tree species suitable for use as supplements and how to overcome the anti-nutritional factors.
