Effect of feeding chemically treated mustard cake on growth, thyroid and liver functions and carcass characteristics in kids

Comparative assessment of soybean meal with high and low glucosinolate rapeseed–mustard cake as protein supplement on performance of growing crossbred calves

“…However, the serum urea levels of calves remained close to the normal physiological values (8–27 mg dL −1 ) throughout the experiment 33. The comparable creatinine, AST and ALT levels observed in this study, as also reported by many earlier workers,35, 36 indicates no adverse effect of glucosinolates on kidney, liver and muscles. In contrary, other workers reported elevated SGOT values due to the influence of intermediate metabolites of glucosinolates present in mustard cake 24, 37…”

“…High erucic rapeseed oil was not metabolised, and reported to impair myocardial conductance and peripheral vascular system, decrease survival and coagulation time and increase blood cholesterol in human beings 2. The use of rapeseed–mustard cake (RMC) as a protein supplement to ruminants is constrained due to its higher level of glucosinolates that have variable adverse effect on palatability, dry matter (DM) intake, nutrient utilisation, thyroid hormone production, carcinogenicity and overall performance of the animals 3–5. Although single or double low (00) varieties (low erucic acid and low glucosinolate) of rapeseed have been developed in Canada, Europe and Australia, these varieties could not be introduced in India due to their poor production performance under Indian agronomic conditions.…”

A comparison of the proximate, fibre, mineral content, amino acid and the fatty acid profile of Marula (Sclerocarya birreacaffra) nut and soyabean (Glycine max) meals

“…Intensive livestock production is dependent on the availability of nutritionally adequate feed ingredients for the formulation of livestock feeds . The feed ingredients produced by crop agriculture in the region are characterized by seasonal availability and shortages in the case of dietary energy and protein sources . The challenges around seasonality and inadequate production are exacerbated by the competition between humans and livestock for dietary energy and protein sources .…”

Coprodutos de crambe (Crambe abyssinica hoechst) na alimentação de ruminantes

“…A irradiação por micro-ondas (2,450 MHz por 2 minutos e meio) em pré-condicionamento (umidade de 13 g/kg, por 24 horas, a 4 ºC) pode inativar a enzima mirosinase e os compostos de glicosinolatos (Maheshwari et al, 1980). Os tratamentos com sulfatos de zinco, cobre, ferro e níquel também podem ser utilizadas; Das and Singhal (2005) confirmaram a redução de glucosinolato após o tratamento de 1 kg de farelo de colza em dois litros de sulfato de cobre (6,25 g CuSO 4 . 5H 2 O), sendo posteriormente exposto a secagem em estufa, a 60 ºC.…”
