“…reduction in serum T 3 and/or T 4 levels, were because of leucaena feeding wherein mimosine is converted to 3,4-DHP and to 2,3-DHP. The latter two are known to have goitrogenic effects (Hegarty et al 1979; Jones & Jones 1982; Jones & Hegarty 1984; Gupta et al 1988; Senani et al 1996; Haque et al 1996).…”

SU MMARYFour Karan/Friesian crossbred (HolsteinrTharparkar) dairy cows in late lactation (>200 days) were fed a basic diet of green maize and concentrates with an increasing proportion of Leucaena leucocephala (leucaena) leaf meal (LLM). The proportion was gradually increased from 0 . 25 of the dry matter intake (DMI) in the first week to 0 . 50 in the second, 0 . 75 in the third and ad libitum in the fourth week. Mimosine, 3,4-dihydroxy pyridine (3,4-DHP) and 2,3-dihydroxy pyridone (2,3-DHP) levels were determined in milk, serum, urine and faecal samples. On average DMI of leucaena was 0 . 023-0 . 025, 0 . 025-0 . 027, 0 . 027-0 . 028 and 0 . 022-0 . 025 of live weight (LW) during the first, second, third and fourth week, respectively. Mimosine, 3,4-DHP and 2,3-DHP appeared in the blood serum during leucaena feeding and continued appearing up to sixth week of experimental feeding even after the withdrawal of leucaena from the 34th day onwards. Similarly, excretion of mimosine, 3,4-DHP and 2,3-DHP were observed even after withdrawal of leucaena from the diet. The feeding of LLM resulted in a reduced level of T 3 (Triiodothyronine) and T 4 (Thyroxine) within a week of LLM feeding. The level of T 3 and T 4 improved to normal after withdrawal of LLM from the diet. The serum aspartate transferase (AST) and serum alanine transferase (ALT) activities were within the normal range. Leucaena feeding improved milk yield and composition only up to 3 weeks of feeding. The concentration of mimosine, 3,4-DHP and 2,3-DHP in milk was 0 . 33, 0 . 05 and 0 . 02 that of blood, respectively. The secretion of mimosine, 3,4-DHP and 2,3-DHP in the milk might be a concern for health of the offspring of leucaena-fed animals as well as human beings consuming such milk.

“…Some studies with goats fed goitrogenic feeds have dealt with the effects of iodine supplementation on TH (Haque et al, 1996;Pattanaik et al, 2001 and2004) and some blood metabolites (i.e. glucose and cholesterol; Pattanaik et al, 2004).…”

Aim of this work was to evaluate if long-term dietary supplementation of potassium iodide (KI) to dairy goats can influence metabolic and hormonal parameters. Thirty Sarda crossbred dairy goats were divided into three groups, which were orally administered 0 (control group; CON), 0.45 (low iodine group; LI) or 0.90 (high iodine group; HI) mg of KI/day, respectively. The daily dose of KI (76.5% of iodine) was administered as salt dissolved in water for 8 weeks. Plasma contents of nonesterified fatty acids (NEFA), urea, glucose, insulin, free triiodothyronine (FT 3 ) and thyroxine (FT 4 ) were determined weekly. Iodine supplementation increased significantly the FT 3 hormone ( P 5 0.007) and FT 3 /FT 4 ratio ( P 5 0.001) and tended to influence the FT 4 hormone ( P 5 0.059). An iodine level 3 week of sampling interaction for NEFA ( P 5 0.013) evidenced a temporary concentration increase in supplemented groups. The 'Revised Quantitative Insulin Sensitivity Check Index' increased with KI supplementation ( P < 0.01). Blood urea nitrogen (BUN) and insulin were lowered ( P < 0.01) by iodine supplementation (groups LI and HI; P < 0.01). The glucose concentration evidenced an iodine level 3 week of sampling interaction ( P 5 0.025) due to an unexpected and temporary increase of its concentration in the CON group. Glucose concentration was decreased by KI supplementation only in LI group ( P , 0.05). In conclusion, the daily supplementation of low doses of KI can improve insulin sensitivity and decrease BUN in dairy goats.
