Plasma concentration of thyroid hormones in lambs fed poultry offal meal in replacement of soybean meal at two energy levels.
Journal - DTW. Deutsche tierärztliche Wochenschrift (GERMANY )
Sixty growing Najedi ram lambs (23.5 kg BW: 3 months old) were divided randomly to 6 equal groups. Each group was fed on different (isonitrogenous) diet, being either high energy (2.79 Mcal ME/kg DM) or low energy (2.15 Mcal Me/kg DM), supplemented with either 0.5 or 10% poultry offal meal (POM) in replacement of an equal amount of soybean meal (SBM). Feeding was ad libitum for 15 weeks experimental period. Thyroid hormones levels in plasma were determined during the last 7 weeks of the experiment and were related to feed intake and body weight during the same period. Lambs fed high-energy diets showed higher (P < 0.01) levels of both thyroxine (T4) and triiodothyronine (T3) compared to those fed low-energy diets leading to lower T4 to T3 ratios. There was more conversion of T4 to T3 for more utilization of food by the lambs fed the 10% POM diet of the high-energy content.

Effect of milking interval on secretion rate and composition of camel milk in late lactation.
Journal - The Journal of dairy research (ENGLAND )
The effect of milking interval on secretion rates of milk and milk constituents was studied in four milking camels during late lactation. An interval of 4 h produced the highest milk secretion rate compared with 8, 12 and 16 h intervals, and rates tended to decline with increasing milking intervals. Secretion rates of organic (lactose, SNF, fat and protein) and inorganic milk constituents (sodium, potassium, calcium and magnesium) generally followed similar patterns of decreasing secretion with increasing milking intervals. Many of the values for different intervals were significantly different.
