Abstract:
Goats are generally kept quite a lot and are livestock that have the potential to produce meat to meet protein of animal origin. This study aims to determine the difference between the body dimensions of local goats in Ladongi District, East Kolaka Regency with the research material of 165 Kacang goats and 121 Jawarandu goats. Peanut goats were divided into 3 age groups, namely (≤12 months, 13-24 months, >24 months) each with 87, 46, 32 heads, and Jawarandu goats were divided into 3 age groups (≤12 months, 13 months). -24 months, >24 months) each were 49, 33, 39 using a purposive sampling research method. Research parameters include the body measured includes body length, shoulder height, chest circumference, chest depth, hip height, hip width, and body weight. The data obtained were processed to obtain a correlation (r). The results showed that the age difference was very significant. The conclusion of the research variable that has the strongest correlation value in estimating body weight is chest circumferenceKeywords:

Four different treatments were used to compare the influence of furnishing feed and water (with and without neomycin) to baby chickens at different times. The experimental period was 9 weeks. Two assays differences were conducted according to the seasons — Winter and Summer. In the growing period there was observed statistically significant difference among the treatments as to body weight. Feed and water (Summer) furnished at the same time produced better body weight. From 0-63 days, no statistically significant differences were among the treatments groups as to body weight, feed efficiency, and percentage of mortality.

The experiment was carried out at the Animal Farm / Department of Animal Resources/ College of Agriculture, University of Baghdad, to study the effect of using different percentage of concentrate to roughage in fattening calves .Two equal groups of Holstein Frisian calves, with age about eight months and at average weight of 228.8±21.2&227.8±9.12 kg /hd respectively. The calves placed in two neighboring barn. The animals fed by 3% live weight in the first two weeks then the ratio was raised to 4% of the live weight to the end the experiment. The animal’s weights and some body measurements were recorded at the beginning of the experiment, then after two weeks until the end of experiment (body wt., Chest circumference, withers height, abdominal circumference, body length). The average daily gain in the first group was 0.957 kg/hd while the average daily gain was 0.970kg/hd in the second group. In the end of experiment the weight of calves in the first group were 1428 kg / Group, while the weight in the second group was 1430 kg / group.. The amount of roughage consumption in the first and second group 1594.4 and 1070.6 kg, While the amount of concentrate consumer in the first group 1064kg and the second group was 1549.8kg. It can be concluded from this study that the use of alfalfa hay to feed concentrate diet at the level of 60 : 40 from daily feeding in the fattening Holstein Frisian calves at the age of eight months is the best because it reduces the costs and to achieve the desired purpose.

In countries where the marketing of beef cattle is carried out by live weight, the need for weighing equipment in the market place causes substantial difficulties for developing countries, especially where cattle production involves rural households. A dataset consisting of 504 male Kamphaengsaen beef cattle was collected at Kasetsart University, Thailand, comprising 234 feedlot cattle (FL) and 270 grass-fed cattle (GF). Measurements were recorded for body weight (BW), heart girth (HG), withers height (WH), body length (BL), shoulder width (SW), hip width (HW), shin circumference (SC), and tail circumference (TC). The correlation as measured by the coefficient of determination, between BW and linear body measurements was highly (P < 0.0001) significant. All of the seven body measurements were modeled and the three body measurements that provided the best fit were HG, BL and TC accounting for 90% of the body weight in the feedlot animals and 87% in the grass-fed animals. The high values for coefficients of determination between the body weight and the linear body measurements of the Kamphaengsaen cattle in this study indicated that the variables or their combination could be used to estimate or predict the live body weight of these cattle. The prediction equations in the present study showed no significant (P = 0.99) difference (with means of live body weight of feedlot and grass-fed respectively in brackets) between actual live body weight (413.2521 ± 88.6010, 216.0667 ± 50.0380) and live body weight predicted with the equations from the present study (413.2307 ± 84.3010, 216.0536 ± 46.8750).

Abstract This study aims to compare three programs of feeding broiler conducted on 120 Ross 308 chicks at one day of age distributed to three treatments of 4 replicates by 10 birds each. T1 given 3 phase (starter, grower, finisher) rations during (1-14,15-28, 29-42) days respectively, T2 given a 2 phase (starter ration from 1-28 days and finisher ration from 29-42 days), T3 given a (1 phase) grower ration from 1-42 day. Feed and water have been given ad libitum. All chicks were reared in a semi-open house in pens with a dimension of 1.25 × 1.25 m. The results showed that there was an insignificant difference between treatments in live body weight, total and daily weight gain, Total and daily feed intake except 3-4, 5-6, 0-6 weeks, T3 was significantly less than T2 during the total period, protein intake was significantly different except at 1-2, 4-5 weeks, T3 was significantly higher than T1 in total period 0-6 week. There was an insignificant difference in feed or protein conversion ratio at all studying periods. There was an insignificant difference between treatments in all carcass traits. The difference between treatments in relative growth rate was less than 1%. The second treatment showed a small improvement in economic efficiency by about 2%.
