Feeding management experiment was conducted during winter at Small Ruminants Training and Research Centre, UVAS, Pattoki on sixteen lactating Beetal goats divided into four groups four in each according to RCBD arrangement kept under tie stall intensive management for a period of thirteen weeks. Group A was given ad libitum roughages only (control), while groups B, C and D were given ad-libitum roughages and concentrate @ 0.5, 1.0 and 1.5 % of body weight, respectively. The data on daily DM1, milk production and composition, weight gain, blood bio-chemistry, feed efficiency and milk production economics was collected and analyzed. Concentrate ration prepared for feeding to goats was having 17.41, 83.26 and 71 % Crude protein, Dry matter and Total Digestible Nutrients, respectively.

The Beetal goats fed on Ti, T2, T3 and T4 consumed daily 1.144±0.005, 1.322±0.005, 1.467±0.005 and 1.604±0.005 kg dry matter, respectively. Statistically significant (P<0.0 1) differences between treatments were observed. Highest milk production per day (771.34±5.54 ml) was recorded in T2, followed by T4, T3 and Ti. Statistically significant (P<0.01) differences in milk production between treatments were noted. The fortnightly weight gain in goats was 1.17±0.16, 1.16±0.19, 1.37±0.17 and 1.62±0.17 kg in treatment 1, 2, 3 and 4, respectively. Statistically analyzed data showed non significant (P>0.05) differences between treatments. The milk analysis performed in the milk testing laboratory of Animal Product Technology Department and goats kept on treatments Ti, T2, T3 and T4 showed milk fat contents of 4.65±0.13, 4.29±0.13, 4.42±0.13 and 4.67±0.13. SNF % in goats was 6.36±0.30, 7.47±0.30, 7.05±0.30 and 6.46±0.30, respectively. Non significant (P>0.05) differences in fat and SNF contents between treatments were observed.

Blood sample were analyzed for "albumin, total protein, triglyceride, urea, blood
glucose and cholesterol in the WTO quality control laboratory UVAS, Lahore. The blood albumen contents were 2.56±0.20, 2.38±0.20, 2.89±0.20 and 3.01±0.20 g/dl in goats on treatment 1, 2, 3 and 4, respectively. Total Protein values were 8.25±0.19, 8.24±0.19, 8.11±0.19 and 7.80±0.19 g/dl and Triglyceride were 12.23±0.49, 15.00±0.49, 15.00±0.49 and 16.03±0.49 mg/dl in goats on treatment 1, 2, 3 and 4, respectively. Mean Urea level was 1.35±0.04, 1.32±0.04, 1.36±0.04 and 1.45±0.04 mg/dl, mean Glucose level was 23.42±1.82, 30.28±1.82, 59.59±1.82 and 61.52±1.82 mg/dl and Cholesterol level was
74.91±3.17, 93.66±3.17, 88.26±3.17 and 110.81±3.l7mg/di in treatment 1, 2, 3 and 4, respectively.

Feed efficiency was highest (0.59) in goats on Ti, followed by T2 (0.58), T3
(0.49) and T4 (0.46). The goats fed on T2 showed highest gross margin of RS. 9.17/litre of milk produced followed by Ti (RS. 8.98), T3 (RS. 7.51) and T4 (RS. 7.93).

CONCLUSIONS
It was concluded that different levels of concentrate supplementation improved the milk yield in lactating goats; however, the effect of supplementation on milk composition was non-significant. During winter season better performance of Beetal goats can be attained in terms of increased milk production, improved gross margin and more economically on 0.5 % concentrate supplementation in combination with roughage feeding.
