Use of live oocyst vaccine in the control of turkey coccidiosis: Effect on performance and intestinal morphology

An experiment was conducted to determine the effects of different coccidiosis-preventing programs on performance and intestinal morphology of commercial turkeys. Three hundred fifteen1-d-old female commercial cross turkey poults (British United Turkeys, BUT Big 9) were distributed into 3 treatments with 5 replicates of 21 birds each. Three programs were evaluated from 1 to 70 d of age, where program 1 had no anticoccidial drug and no vaccination against coccidiosis; program 2 had an anticoccidial drug (maduramycin 1%, 5 ppm); and program 3 had a vaccination (commercial vaccine, 4 species of Eimeria). All the groups were challenged with a dose of oocysts sporulated (20,000/bird) of 2 species of Eimeria at 21 d of age. In the growing phase (d 0-28), BW, BW gain, and FCR were significantly greater in treated groups compared with control group. In the fattening phase, the performance was not affected by treatments. Treatments and coccidiosis challenge had no significant effects on intestinal villus height. These observations support other reports that confirm live oocyst vaccination can be used effectively as a preventive against avian coccidiosis in commercially reared turkeys.

Body Composition and Net Energy Requirements for Maintenance of Non-Castrated Water Buffaloes (Bubalus bubalis)

The research aimed to estimate body contents of protein and energy and net requirements of energy for maintenance of buffaloes, slaughtered at different stages of maturity. There were used 14 Mediterranean intact males with initial average body weight of 352.2 +/- 24.3 kg and average age of 24 months. The animais were randomly divided into four experimental groups. One group was designed to slaughter at the beginning of the experimental period (IS). The animals of another group were restricting fed, receiving, individually, levels of protein and energy 15% above maintenance (RF). The animals of the two remaining groups were individually fed ad libitum (SW450 and SW500) to reach weights corresponding to 100 and 110 percent of the mature weight of the buffalo cows (respectively 450 and 550 kg). The ration contained ground-corn cobs, soybean meal, urea, minerals, and signal-grass (Brachiaria decumbens) hay, with a concentrate: roughage ratio of 50: 50 and 13% of crude protein on a dry matter basis. To estimate changes in body composition inside the range of weights included in the trial, linear regression equations of log protein (kg), fat (kg) and energy (Mcal) as a function of log empty-body-weight (EBW), in kg, were fitted. Energy requirements for maintenance were obtained as estimated heat production at zero level of energy intake. Buffaloes submitted to fattening in feedlot presented early body fat deposition, and had with the same live weight lower protein content and higher fat content and energy per unit weight than european-zebu crossbred cattle.

Desempenho e características dos dejetos produzidos por cabritos em diferentes idades e alimentados com diferentes proporções entre volumoso e concentrado

This study was conducted to evaluate the performance and characteristics of manure produced by Saanen goats with 90, 120 and 150 days of age and fed three diets, diets 1 = 80 % roughage (R) and 20 % concentrate (C), diets 2 = 60 % R and 40 % C, diets 3 = 40 % R and 60 % C. Were evaluated 24 goats (divided into three groups according to diet ) during the fattening stage, making up the collection of waste at 90, 120 and 150 days of age to quantify the mass of manure produced each day, beyond the content of N, P, K, Ca, Mg, Na, Fe, Cu, Zn and Mn. The animals were weighed weekly and during the collection of waste is evaluated the digestibility of DM, CP and NDF, in addition to the estimate of feed conversion and rate of waste. The best results of feed conversion coefficient of waste and the apparent digestibilities of DM, CP and NDF occurred at the age of 150 days and in animals fed diets containing higher proportions of concentrate. Insofar as the increased age of the animal and level of concentrate in the diets were verified higher production of faeces. All nutrients were also affected, with higher concentrations occurred in the feces of animals at 150 days old and fed with diet 40% R and 60% C.
